DIY high pressure washer coupling. Do-it-yourself compressor washing. The operating algorithm is as follows

Since I didn’t see the clutch cylinder, I didn’t understand much in the diagram either. Therefore, the following questions arose:

– cylinder diameter and piston stroke?;

– the ratio of the lever arms?, one arm, if I understood correctly, is 35 mm, and the second?;

– maximum pressure, which the compressor develops?

And also - Lefty, I didn’t understand about 160 atm and the sound volume. The volume should not depend on the initial pressure. It depends on the muzzle pressure, or in other words, on the air flow and on the design of the muffler. Those. or you have a bad one impact mechanism or muffler. If you fill a cylinder at 160 atm, then to what pressure do you fire, what is the energy and number of shots.

HP pump. I'm not an expert in hydrodynamics.

Therefore, I ask for help so as not to step on the notorious rake.

Sincerely, Vladimir

Connection tube too long - large dead space

It is not advisable to make the outlet hole on the side (in this design), see the previous paragraph.

Yes, I would also seal the HP cylinder

The rest can be seen from the picture

I almost forgot: there must be a bypass valve at the outlet (near the pressure gauge)

High pressure tank compressor!? Who knows what?

A couple of months ago I saw one of these at the market and held it in my hands. The seller asked for about $40, didn’t buy it, was greedy to take a “pig in a poke,” but now it’s gone. The compressor is not large, weighing about 8-10 kg (I don’t remember exactly), two-cylinder, V-shaped cylinder arrangement different diameters. The drive is connected to the crankshaft splines, compactly.

Operating pressure 150kg\cm2. Used to start a diesel engine. But, since the equipment is military, maybe we can try to squeeze out more? In general, additional information is needed:

1 Drive power;

2 Nominal crankshaft speed;

3 Possibility of upgrade?

Regards, Oleg

The compressor is not an AK150, but if so, it was also used in the T80 to pump cylinders up to 150 atm. 3-stage design, one cylinder with 1 stage, the second 2 stages. I'll try to find the exact specifications.

DIY high pressure washer

High pressure washer - convenient device, which allows you to easily wash your car, as well as other surfaces in your home. Thanks to the strong water pressure, such devices are able to clean even heavily soiled surfaces without the use of detergents.

Such devices are usually installed in car washes and cost a lot of money. The Karcher high pressure washer has deservedly gained popularity, but not everyone can buy it. Therefore, for use at home, you can make a car wash with your own hands. A homemade car wash is an excellent alternative to professional Karcher devices, which you can assemble yourself from available materials.

Industrial pressure washer

What is needed for making

To make a Karcher high pressure washer you need to find suitable materials. You can use scrap items or buy new ones at the store. So, to create a mini-wash you will need:

Water container. The container will contain water that is used for washing. The tank should have a capacity of about 5 liters, otherwise you will have to constantly refill the car wash near the water source. You should not choose a container that is too large, as washing will be very heavy. You can use an old one as a water reservoir. plastic canister or a bottle. When choosing a container, you need to make sure that there are no seams at the bottom of the tank.
Gun for irrigation hose. This attribute can be purchased at any store gardening tools. In addition, you can make a gun yourself.
Rubber hose with a length of 0.5 to 4 m.
Several hose connectors.
Sealant.
Using a simple set of equipment you can assemble a Karcher type sink. Also, a homemade car wash will require the use of a set of tools that can be found in any home: a sharp knife, a compressor or a car pump.

Making a high pressure washer from a canister

How the device works

A DIY high pressure washer will work on the same principle as conventional car washes. The water is supplied through a rubberized hose under high pressure. Air is pumped into a container with water by a car pump, which creates a overpressure. Water is pressurized to the outside and released when the trigger of the watering gun is pulled. Thanks to the strong water pressure, a car wash can clean any surface.

IN in this case the pump is used solely to pump air into the tank. You can replace the constant use of a pump by installing a pump that will allow you to increase the pressure manually. Also an alternative to automobile pumps are plunger pumps.

Types of high pressure washers

Plunger pumps – modern devices, which are classified as metering-type hydraulic devices. The plunger pump independently mixes water and detergents in selected proportions and supplies the mixture under high pressure. The disadvantage of installing such a pump is the excess final weight of the car wash.

How to assemble a car wash with your own hands

Initially, you need to prepare a water tank. To do this using sharp knife It is necessary to cut a hole in the lid of the canister, which will be narrower in diameter than the nipple. After this, a nipple is threaded through the inside of the lid.

Advice : If the hole is larger than required, the gaps must be additionally sealed.

Through the nipple in the lid, the pump will pump air into the tank, and will also fill with water and detergents.

Next, you need to prepare a system for connecting the canister to the watering gun. To do this, you need to cut a hole in the bottom of the canister close in diameter to the coupling. The coupling is attached from the inside of the canister; you can wind it using a piece of wire. After threading the hose connector, sealant must be applied around the circumference. A fitting is also attached to the coupling.

Approximate diagram of a homemade high pressure washer

After the sealant has dried, you can begin preparing the sink for use. To do this, plug the fitting with your finger and pour water into the canister. You can also add any detergents to the tank (specialized detergents for cars or household chemicals). The nipple must be connected to a car pump and gradually inflate the canister with air. While performing this action, you need to ensure that the canister does not inflate too much. If it was decided to install a plunger pump or pump, then they are attached to the fitting using connecting hoses.

Having completed these steps, a rubber hose is connected to the fitting, at the end of which a watering gun should be attached.

Setting up the operation of a homemade high pressure washer

Advice : You can check the correct assembly by pressing the trigger of the gun. If, as a result, water begins to flow from the gun with strong pressure, then the device is assembled correctly. If this does not happen, then the canister is leaking air and you need to check all connections again and, if necessary, treat them with sealant.

Thus, it’s easy to assemble a mini-wash with your own hands; just follow the suggested instructions and buy a minimum set of equipment. As a result, within an hour you can make car wash, which in terms of quality of work is no different from professional equipment in car dealerships.

Plunger water pump - distinctive features and use in everyday life

If you decide to do automobile business in the form of a car wash or simply decided to keep your personal car perfectly clean without resorting to maintenance services, then when developing a design for washing with your own hands, you cannot do without the use of high-pressure pumps. Most the best option in this case is the use of plunger models that provide required pressure in the system and different high performance and price.

What is a plunger pump. Operating principle

The main element of the pump is the plunger - a long cylinder-shaped displacer with a small diameter. Unlike the piston type, the seal is located inside the outer cylinder, in which the plunger moves, coming into contact with its walls. During the reverse stroke of the plunger, liquid is sucked into the working chamber through the inlet valve; during forward movement, the inlet valve closes and the liquid is pushed out through the outlet.

Rice. 1. Design and principle of operation of a plunger pump

Differences between plunger pumps and piston pumps

Many people confuse plunger and piston type pumps due to the similarity of the operating principle and design (a displacer moves in the working cylinder). However, there are significant differences that make plunger pumps indispensable devices in many areas.

The plunger has a cylindrical shape, which makes it possible to process its surface with maximum precision and high purity, which cannot be said about inner surface cylinders, the processing of which is technically and technologically difficult. This allows the plunger to be adjusted as accurately as possible to the surface geometry of the working cylinder, which has a positive effect on the output pressure indicators.
Unlike a piston with a short length of the working surface of the ejector, the plunger cylinder has an elongated shape, which makes it possible to place a large number of seals along its stroke and, accordingly, obtain a higher pressure at the outlet.
Seals in plunger types are located on inside working cylinder, which is technologically difficult to process with high cleanliness and precision, the plunger in contact with the seals, on the contrary, has a very high processing class - this factor also makes it possible to obtain very high pressure in plunger pumps.

In modern high-quality plunger pumps, manufacturing precision is very high - the working cylinder moves inside the outer one with a gap between the walls of about 2-3 microns, and the seals are placed with outside to the plunger at its inlet and outlet of the cylinder.

Unlike piston types, working surface which deform when in contact with liquid at high pressures, in plunger pumps the rigid and durable working cylinder does not change its shape at high pressures, which makes them indispensable when precise dosing of liquids is necessary.

Rice. 2 Internal structure of a plunger pump

Thanks to your design features plunger pumps make it possible to obtain an outlet pressure 3 times higher than piston pumps with the same working chamber dimensions.

Application area

Plunger models are special-purpose devices that create very high pressure, so they are practically not used in everyday life. The main areas of their use are the industrial sphere, they are used in the following industries:

IN chemical industry for pumping substances with high viscosity and their precise dosage in the manufacture of chemical compounds that do not react with metal.
For supplying measured quantities of water and other high-pressure liquids.
In the oil and gas industry when drilling wells.
In the energy industry in steam generators.
In mechanical engineering in the manufacture of hydraulically driven equipment with operating pressures up to 3000 bar, in the automotive industry in injection systems of diesel engines.
Water plunger pumps are widely used in service centers for car washing.

One non-traditional application for plunger pumps is water jetting and cutting materials. At a pressure of about 2000 bar. A jet of water can remove paintwork or rust without leaving any residue. The technology is widely used in cleaning reinforced concrete structures, the sides of ships and runways. A water jet with a pressure of 3500 bar allows you to obtain the highest degree of cleanliness of WJ-1 surfaces according to the international standard.

Rice. 3 Appearance of the plunger pump

Main characteristics of plunger pumps

Plunger pumps belong to the volumetric type, that is, when the volume of the working chamber increases, liquid enters the device, and when the volume decreases, it is pushed out.

Power consumption. The electricity consumed directly depends on the performance and pressure created; in this regard, plunger models have an advantage over other types due to their high efficiency of more than 90%.
Performance. It is determined by the volume of the pump’s working chamber and has a wide range from tenths of a liter per minute to ten thousand.
Operating pressure. The operating pressure of plunger types varies widely from hundreds to thousands of bar, the maximum value is about 3500 bar.
Models differ from each other in the number of plungers.

The operation of the pump is characterized by increased vibrations, which negatively affect its service life and operational characteristics. Engineering solution This problem was caused by the use in one unit of several plungers operating with a phase shift. The most common are three-plunger models with a stroke offset of the working cylinders of 120 degrees; the maximum number of plungers can reach 6. The implementation of this method is achieved by installing three eccentrics on the engine shaft that control the stroke of the plunger cylinders with a shift of 120 degrees.

Do-it-yourself plunger pump in a car wash device

In everyday life, you can use high-pressure plunger pumps for water when organizing car washes with your own hands.

Fig.4 Hydraulic diagram of a car wash

To do this you will need the following components:

High pressure plunger pump for water 100 - 200 bar. and productivity 15 l./min. Electric water pumps with an electric drive are quite difficult to find; usually an electric motor is connected to them.
Electric motor 2 - 3 kW. with a maximum rotation speed of about 2000 rpm.
Gearbox and V-belt drive for connecting the electric motor and pump. You can directly connect the pump and motor shafts using a soft coupling, which can level out the difference between the shafts and avoid damage in the event of jamming.
Hoses made of reinforced rubber or high-pressure plastic.
A gun with a nozzle and a handle that controls the water supply.
Water tank with recharge from the water main and a filter element at the outlet. The need for a separate tank for washing a car is due to the fact that car shampoos are added to it - this cannot be done when the pump is directly connected to the water main.
For ease of operation in the system, it is necessary to use a pump power adjustment paired with a discharge valve that releases excess water back into the tank.

Fig.5 Do-it-yourself car washing components

The main elements are mounted on a rigid frame, which is equipped with wheels and a handle for ease of movement.

Plunger pumps are quite expensive devices, widely used in industry to create high pressure of working fluids and their precise dosage. In everyday life, they can be used in systems designed for washing vehicles with your own hands.

How to make a high pressure washer with your own hands

What is a pressure washer?

Today, you no longer need energy and time to fight dried-on dirt and dust that has clogged up in secluded corners, because new models appear on the market every year high pressure washers. These devices are used for washing windows, cars, walls and doors of houses, barbecues and other objects that are difficult to clean with a rag or brush. Strong water pressure copes with this task much more effectively and saves money spent on washing the car at a service center; water consumption is also minimal. Therefore, having such a sink in your arsenal is useful for everyone.

Companies leading in the production of high pressure washers - German companies Bosch, Karcher (hence the second name for the sink - Karcher) and Elitech. The average price of these sinks on the market starts from 10,000 rubles. Inexpensive car washes cannot be used for more than one car per day, and the most expensive models are limited to seven cars.

Washing device

The main component of the sink (or Karcher) is the engine, which creates required pressure water. A pump or motor will do (you don’t have to buy a new one, take a working one from an old car), the motor is built into the body of the sink and must be connected to a power source. For the body of the sink (body), choose durable material, thick plastic or metal. Even if you purchase a wear-resistant case, it is better not to use the sink for more than three hours at a time. This will put the washer out of action soon.

Hose attachments are available to facilitate the cleaning process - brushes of varying hardness, soft rollers, standard sprayers. If you purchase a couple of attachments, you can expand the functions of your sink by using it as an automatic mop or steam cleaner (you need to equip the sink with a heater).

Internal pressure

The higher the pressure inside the housing, the stronger the stream of water gushing from the hose, which means the dirt comes off easier. Set the pressure carefully, because water can simply break a fragile car part or glass and leave dents. Manufacturers set the pressure at 150-170 bar, but 100 bar is enough to clean the car.

If the contamination cannot be cleaned with a jet of water, purchase a special nozzle for the hose, a turbo cutter. It will help wash tires, wheels, and remove dirt accumulated in the cracks. You can use the mini-wash both outside and inside the car. If you are using a turbo cutter, you will need a pressure of 160 bar.

Electric pump

Before purchasing and using a pump when designing a sink, read how to choose the right device.

The material of the pump determines its wear resistance. A bad option is a plastic pump; it will soon fail if you use it for more than 20 minutes at a time. Expensive but reliable pumps are made of brass because it does not corrode. These pumps are rarely found in commercial car washes.

How to use the mini-wash

To wash worked properly, follow these recommendations.

Be sure to check the operation of the washer before you start using it, this will save your time and health.
Clean and change the filter installed in the car wash after each use.
If the washer uses electricity to operate and the source is unstable, provide it with a battery.
Do not let children use the sink.
If repairs are necessary, do not hesitate to carry them out. Replace damaged sink components.
Update the device gaskets.
Protect your sink from temperature changes.

How to make a Karcher yourself

Although car washes have achieved widespread use, they come at a high price. So, if you want to do the sink yourself, you will be needed:

canister;
irrigation hose with gun;
pump;
union;
canister lid;
tubeless wheel fungus;
rubber gasket;
coupling.

These are the components of the future car wash. Materials that will come in handy during the manufacturing process:

First stage. Selection of components.

The required volume of the canister depends on you and the purposes for which you will use the washer: for passenger car A five-liter canister will suffice. Drivers carry a car wash in their luggage, so choose a body based on both volume and dimensions.

The irrigation hose must be strong and flexible and should not be twisted or broken. Hoses with nylon braid are considered durable. A hose consisting of several layers is more reliable. Don't skimp on this component. The only requirement for the gun is that it must hold tightly to the hose.

The pump can be foot-operated or automatic. We won't need the high power of this pump, so don't buy an expensive one. Using an automatic pump is much more convenient than a foot pump, since you do not have to constantly drag the pump from place to place and do unnecessary work with your foot. However decisive role The cost of the pump plays a role, the automatic one is three times more expensive.

Choose the fitting and coupling at your discretion, the main thing is that they are in close contact with each other. It is preferable to purchase both the fitting and the coupling from the same material (plastic or metal).

Second phase. Preparing the canister.

Drill a hole in the canister that is the right size for your coupling. Insert a coupling with a screwed-in fitting into this hole. Secure the structure with sealant so that the coupling does not pop out during operation, and the required pressure is maintained in the canister.

Third stage. Cover assembly.

The lid needs to be strong, solid and suitable for the canister. To prevent air from escaping from the canister, attach a rubber gasket to the bottom of the lid. Then make a hole in it and insert the tubeless tire fungus into it.

Fourth stage. Assembly of the structure. Additional functions.

Screw the lid on the canister tightly, connect the cord from the pump to the fungus, attach the free edge of the hose to the hole made in the canister using a fitting. The homemade sink is ready. The principle of operation of such a washer is simple: using a pump, air is pumped into a canister of water (the canister is not filled to the brim with water). Create pressure up to 0.3 bar or higher if your canister can handle it. Under the influence of pressure, water streams out of the gun when you press the handle.

If you will use the sink during the cold season, equip your sink with a special burner for heating the water. For these purposes, you will need a larger canister; it will lose mobility, but with the help hot water The car is cleaned of heavily dried dirt.

Provide a power source for the washer. If the washer runs on fuel (gasoline or diesel fuel), then there will be no problems with moving it. When planning an electric car wash, make sure you have a working and accessible source of electricity. In this case, you are unlikely to be able to freely transport the sink from place to place, but you will not have to spend money on expensive fuel.

Decide in advance what you are using the sink for. If you want to clean the windows of a house or the wheels of a car, then a compact, mobile washer on wheels and with a long hose will suit you. When using a sink on a production scale, you will not need its ability to move, so it is better to design a stationary sink. It connects directly to the water supply. If the need arises, set up automatic water supply to save money.

While you can save on water consumption, you cannot save on purchasing sink components. To prevent the item from becoming dirty after washing, purchase special filters. You don't need an expensive filter to purify the water to drinkable condition. A filter is needed to purify the water, at least from debris that will disable the sink.

You can even make money by designing a pressure washer if you open a car wash. The main thing is that the sink you make works. Using a car wash, you can clean bicycles, mopeds, cars, trucks and their components.

How to make a Karcher powered by a cigarette lighter

This sink design does not require any costs. Below are instructions for creating a more complex model:

windshield washer motor;
irrigation hose with gun;
cigarette lighter (motor power supply), cigarette lighter plug;
two hoses 3 meters long, one hose must fit freely into the other;
corrugated hose with a diameter of 25-30 millimeters;
switch;
M8 bolt, washer and nut;
two plastic canisters (volume 10 liters);
6 self-tapping screws;
two-wire electrical wire 5-7 meters long;
plastic sleeve;
power cable;
brush for washing a car.

First stage. Creating a hose.

We make a small hole in the bottom of one of the canisters. A thinner hose (up to 6 millimeters) and a two-core wire are placed inside a thick hose (diameter 10 millimeters or more). Then the hoses we have fastened are inserted into the opening of the canister. A plastic sleeve is inserted into the free end of the hose. Next, a thin hose is attached to the washer motor, and the wires are also connected to the motor.

Second phase. Creating a canister with a double bottom.

The second canister is cut approximately in the middle in order to subsequently make a second bottom with a shuttle out of it. The motor is fixed to the second bottom of the canister; for these purposes, a homemade clamp is used, which can be made from the remains of a cut canister. For this we need an M8 bolt and a little sealant.

The wires are also secured using self-tapping screws and sealant. Then they connect, again using self-tapping screws, the body of the structure: the second bottom and the hinged lid.

Third stage. Completion.

Using the power cord, the wires are connected to the cigarette lighter. A hole is made in the brush for the button, the switch is secured. The brush itself is mounted on the edge of the hose with a plastic sleeve. Use the attached diagrams in your work to better understand the text.

Do-it-yourself high-pressure washer: photo, device, pressure

How to make a high pressure washer with your own hands What is a high pressure washer? Today, you no longer need energy and time to fight dried dirt and dust that has clogged up in secluded corners, because

Application of foam for contactless car wash car provides better surface cleaning. The advantage of this washing method is also its “delicacy” - the foam will not damage the body. Therefore, many car enthusiasts strive to make a foaming agent for car washing with their own hands.

Principle of operation

Using high pressure, a jet of foam is supplied, which not only removes all contaminants from the surface, but also disinfects it. The internal structure of the unit allows you to create foam required density and apply it evenly to the car. Foam is formed in several stages:

A stream of water passes through a car shampoo suitable for a foam generator.
It mixes with the air stream and foam begins to form.
At high speed, the resulting substance is sent to a special foaming “tablet”.
Foam of the required density is already coming out of it.

The foaming agent allows you to clean very quickly, and it also significantly saves water. A small amount of water is sufficient for the jet; high pressure will ensure the required spray speed and surface area to be treated. Thus, a foaming agent and a high-pressure car wash very quickly take a leading position in the list of necessary tools for the garage, according to car enthusiasts.

How to assemble a foam concentrate

The foam production unit itself consists of several parts:

Compressed air cylinder.
Gun for application.
Mixer parts.

Professional foaming agent industrial production It is very expensive, so it makes sense to assemble a foam generator for car washing with your own hands.

It will be much more affordable in price, and the operating efficiency will remain the same. There are several ways to create a foam concentrate:

Production of a compact foam concentrate.
Creation of a traditional foam generator.
Making a foaming agent from a canister.

To make it using the first method, you need adjustable wrenches, grinder, and other tools, as well as the materials themselves for manufacturing: a tube 50 cm inch in diameter, a washcloth made of polyethylene strips, pipes, a hose. Part of the pipe is filled with a washcloth, which replaces the tablet and promotes the formation of foam. You need to put a filter on one end of the pipe, and a plug and tee on the other. It is on this part that the supply tap is installed compressed air. A fitting and a hose for foam are attached to the side where the filter is located. Such a foam generator will not last very long, but it will be cheap.

In the same way, you can make a foam nozzle with your own hands for washing a car. Sometimes motorists need a separate foam nozzle if it was not included in the purchased factory-made washing kit.

This DIY device will likely work much more efficiently than many commercially produced foam guns.

The second method will make it possible to make a unit that is close in design to an industrial one. To do this, you will need a compressor that will create a sufficient level of power. In addition, you will need to take a container with thick walls. This could be a garden sprayer.

Metal tubes must be screwed into the container from the sprayer. At one end you need to install a fitting and a check valve, and at the other - a container for connecting with a foaming tablet. The air supply for this foam concentrate must come from below. After finishing assembling the foam generator for a car wash with your own hands, you can use it.

You can use more than just a garden sprayer as a water container. The most reliable option is a propane tank, as it can withstand high pressure.

The third method of creating a foaming agent is to use a plastic canister. This allows you to make the necessary unit cheaply and quickly. You will need a long tube of small diameter, which must be filled with fishing line or something that replaces it. A fitting is installed at one end of the pipe, and a special adapter with two tubes is installed at the other. Hoses and taps through which water is supplied are attached to it. On one side, the foaming agent is attached to a container with washing liquid, on the other, a compressor.

All the described methods allow you to make a foaming agent for a car wash with your own hands.

You should not use a foaming agent or a high-pressure car wash for a very long period of time. This may cause damage.

Creating a car wash with your own hands

Thanks to a high-pressure car wash, you can easily clean your car from any dirt. The combination of strong water pressure and a special nozzle, which allows you to cover a larger volume, is liked by motorists. The versatility of such a unit also makes it attractive.

In many stores you can buy an industrial car wash, but the cost will be quite high. To save money, as well as for the pleasure of doing something yourself, many motorists prefer to do their own car wash. There are a large number of training videos in which you can find out all the information necessary to create it.

First you need to select the necessary parts. These include:

Pump.
Electric motor.
Clutch.
Water reservoir.
Pump performance regulator.

The pump must be selected very carefully. It will be the most expensive element in the entire structure, but it will last a long time. All important parts of the pump must be metal. In addition, it must be characterized by high performance and resistance to pressure of 150 atmospheres.

A single-phase electric motor with a power of 220 V can be used for a car wash. The connection will be secure and inexpensive. The higher the engine speed, the greater the level of performance. The electric motor will be connected to the pump by a coupling. It would be optimal to use a soft coupling, which can become a fuse if the pump is faulty.

The water reservoir must be large in size so that the pump can operate for a long time without interruption. Water supply tanks are often used. You can attach a mesh at the junction with the hose to prevent any debris from damaging the pump. The material of the container must be chosen carefully, as it must be durable. Thick metal or plastic will do.

To make a high-pressure car wash with your own hands, you must also purchase a regulator for the pump. It will help return some of the water to the reservoir if there is a risk of overloading the pump. All elements are fixed on a special frame. They also add hoses that can withstand high pressure, a brass pump and a spray gun.

The process of washing a car can be made more effective if you attach some kind of brush or other attachment to the water hose.

They will complement the list of car wash functions. If desired, you can turn the sink into a steam cleaner. This will also require a special nozzle for the hose, as well as a heater.

You cannot use the same sink for a long time, as it will quickly become unusable. The purpose for which the sink will be used affects its final dimensions. By appearance washing can be:

Compact.
Large stationary.

The second option is more difficult to use at home and requires a lot of space in the garage.

Knowing how to make a car wash with your own hands, every motorist will think about how to use it correctly.

There are several basic rules of use:

Regular inspection of connections and their tightening will help prevent mechanical damage that can occur from strong pressure.
Inspect the filters before use - cleaning them regularly will ensure an even supply of water.
Grounding the electrical circuit - not only the electric motor must be grounded, but also the plug itself. Then the device will be safe.
Washing should be carried out over the entire surface so as not to damage the paint that covers the car. If a drawing or sticker is applied to the car, then you should not direct a stream of water at this element, as it can lead to cracks in the coating or remove the sticker.
It is advisable to use a battery in case of a poor-quality source of electricity. This will protect the unit from short circuit
Avoid temperature changes - a sudden change in air temperature can lead to damage to the instrument.

When using, you must remember that washing the car is not allowed everywhere. Washing your car near ponds and lakes will result in a fine. This rule, however, does not apply to keeping headlights and glass clean.

You can use a high-pressure car wash not only outside the car, but also inside. This will allow you to clean the interior very quickly and efficiently. Wide choose nozzles and rollers will help you do even delicate cleaning in the car.

If you know how to make a foam generator and how to make a car wash with your own hands, you can save a lot of money. Experienced motorists have everything in their garages necessary materials and tools, so they will only have to spend money on a special car shampoo.

Washing a car with your own hands is a tedious and unpleasant task, and it takes a lot of time. This is especially felt in spring and autumn, when there is mud and slush all around. In order to wash the car yourself and well, you need to change clothes so as not to get dirty yourself. Of course, you can use the services of a stationary paid car wash. But, firstly, there is not always time for this, and secondly, it costs money. You can buy a mini-wash, but the prices for this product are quite high.

The easiest way to do your own washing is to use an air compressor.

A mini-wash with your own hands is simple and accessible to everyone, and there is more than one option for creating this mechanism. By doing it yourself and spending a minimum amount of money on purchasing parts, you will only get pleasure from washing your car.

What materials will be needed?

Scheme of a homemade mini-wash.

This mini-wash will work on the basis of a compressor; all the work can be done independently, that is, with your own hands.

You will need very few parts and materials, so creating it will not cost you much. It is very economical to use parts from old, unused equipment, for example, from a washing machine.

tire compressor;
a suitable capacity of at least 10 liters, you must take into account not only the ease of washing the machine, but also the subsequent ease of storage;
long hose (you can use an old one from a washing machine);
short hose (for example, from a sink faucet);
a fitting with a nipple (it is also not necessary to buy a new one, you can use the old one from the camera);
a brush (perhaps the only thing you will have to buy in the store);
faucet (one that is used to supply water to a washing machine, or any other that you find more convenient to use) is suitable;
rubber gaskets (for reliable sealing, you can also use FUM tape);
sealant.

First, connect the compressor to the fitting using a hose. A tap is attached to the brush, with which you will regulate the optimal amount of liquid throughput.

Accordingly, the tap is also connected to the hose. After connecting all the parts, you can start operating the device.

This is not the only option for creating a mini-wash. you can do it yourself and an automated version, which, of course, is more convenient. Such home washing can work from the car’s on-board network, for example, from a cigarette lighter or simply from an electrical network, but only through a rectifier with a 12-volt output.

Materials for making an automatic mini-wash

The high pressure pump from a car washer is perfect as a compressor for a car wash.

You may already have all the necessary materials. If not, then you can purchase them at the nearest car market or at a specialized auto parts store. An automated car wash is simple enough that any car enthusiast can decide to make it with his own hands.

Such a sink can be useful not only for common days, but also when traveling, when you won’t find paid stationary car washes on the road. Start manufacturing by selecting or purchasing parts, only after purchasing which you can proceed directly to the assembly process.

You also don’t need any special knowledge to create such a necessary thing as an automated mini-wash. Only necessary tools, Availability the necessary details and the desire to make the process of washing your car with your own hands more enjoyable.

First, you need to prepare the canisters; one of them will have to be cut in order to create a “second bottom” where the shuttle for winding the wire and power and the rotating lid will be located.
For cutting, you can use a knife or scissors, depending on the thickness of the canister walls.
Regular drinking water cans are ideal for this.
In the bottom of the whole canister you need to make a hole corresponding to the diameter of the large hose, that is, 10 mm, exactly under the inlet of the canister. On the opposite side you need to make a hole corresponding to the washer.
The washer is attached using a brass M8 bolt, respectively, with a nut and washer, to the outer surface of the bottom of the whole canister approximately in the middle. The motor is secured with a clamp, which can be easily made from a strip of plastic.
To install the hoses, plastic bushings are used. These can even be cases from ordinary felt-tip pens. After fastening, you need to connect the receiving tube from the motor to the bottom of the canister into the hole made in advance, from where water will flow to the motor.
The wires and thinner hose are inserted into the larger diameter hose. You need to insert it into the inlet of the canister and through the hole made in its bottom. For reliability, the hose is secured in the hole with a sleeve.
You need to install a switch or button on the brush; make a choice from these parts yourself. Choose what you find more convenient, because you will perform the entire manufacturing process with your own hands. A button or switch is glued inside the handle.

To decorate it, use a piece of corrugated hose; a diameter of 25 mm is suitable for this. It must be put on the brush handle in advance, that is, before assembly is carried out. Naturally, wires are connected to the switch.

High pressure washers have become widespread among private sector residents and car owners. This phenomenon is caused by the fact that the devices are used for various purposes: for cleaning paths in the garden, for cleaning terraces, and even for washing cars and houses. To become the owner of the unit in question, it is absolutely not necessary to send it to a specialized store and spend a large amount money. You can make a device from a compressor and some other components.

Advantages of homemade equipment

If there is no financial opportunity to purchase a device, or there is a desire to assemble high-pressure washing equipment with your own hands, the instructions given below will be of interest to you. Before you make a high-pressure washer, you should know about the advantages of the technology:

low financial expenses;
possibility of modernization;
functionality at the level of production technology;
fast production;
operational simplicity;
high efficiency;
no need for spare parts and no additional expenses.

Using the equipment, it is possible to effectively, quickly and efficiently wash away contaminants of any degree of complexity. You will be able to cleanse various surfaces car body. A homemade high-pressure washer, made and operated with your own hands, eliminates damage to the surfaces being treated. This quality favorably characterizes the cleansing technique in the eyes of the user.

We make equipment ourselves

First of all, you will need to choose a suitable pump for washing. It is planned to operate the equipment for commercial purposes - make a choice in favor industrial equipment. The main principle remains the choice of a plunger pump equipped with ceramic pistons. The crank mechanism increases the service life. The main parts of a high pressure washer are:

washing filter;
hoses;
additional nozzles;
water containers;
detergents;
sandblasting for washing;
durable wear-resistant body;
High pressure pump;
engine (gasoline or electric).

The principle diagram of how a homemade high-pressure washer works is as follows: water is transported to the container from a special container or water supply, and then pumped through a pump. The maximum load provides pressure up to 160 bar. Water is supplied via a hose to a gun with a nozzle. Let's look at the main stages of manufacturing a high-pressure washer:

The container is equipped with a pump, and the connections must be completely sealed and durable. Fixation involves the use of couplings.
On the other side of the tank you will need to fix a hose that will supply water.
The hose is equipped with a tip that directs the water stream.

An auto-loading valve, available in two variations, will need to be connected to the pump. The first type is represented by a closed valve. The system releases pressure after closing the gun, and then water is pumped from the outlet to the inlet. It is recommended not to operate the device for more than 3 minutes. The valve with inlet is convenient. The liquid is transported through the collector to the container or to the sewer immediately after the pressure is released (depending on the connection option for the sink).

There are two ways to connect the motor to the pump. If you have a motor with a full shaft, it can be connected directly to the pump. The motor shaft is placed on the front bearing, creating additional load. This technique shows the most economical results. If you make a sink with such an engine with your own hands, it will have a significant service life between repairs. This is caused by high starting loads. It happens that it is not possible to remove the pump shaft from the engine. In this regard, it is advisable to install a soft starter.

Another method of coupling the motor to the pump is provided, in which a clutch is used. It is used as a cushion that softens the shock during equipment startup. The coupling serves as a protection that prevents the shafts from being damaged. In order to reduce the load during startup, a soft start can be used. Thanks to this element it is possible to gradually increase the power in the system.

The sink is mounted on a frame. Installation of the electrical component, the gun with the nozzle, and the high-pressure hose is carried out sequentially. It is important that the equipment in question is installed in accordance with the parts manufacturer's recommendations.

Follow the established algorithm for assembling the device, take into account the load present when tightening the bolts. Also use anaerobic fixatives.

The sink must be connected to the water supply system using a hose. The connection hose must be at least 7 meters long. The length of the hose allows you to smooth out pressure drops in the water supply. Provide a filter for washing. It is recommended to use a hose with a check valve, which increases the operating pressure.

Debris accumulating in the filter element of the tank must be removed in a timely manner.
It is advisable to inspect the connections in a timely manner and tighten them if necessary.
Each electrical element of a homemade sink must be grounded, for which use a flexible three-core wire in double insulation. Also, use a plug with a grounding terminal for this purpose.
Connect the power outlet to the ground securely.
The strong jet pressure of the manufactured apparatus is not needed. Otherwise, the injection pump will be overloaded, which is likely to have a negative impact on the paintwork of the equipment. These actions will lead to moisture entering the electrical equipment, damage to the equipment and additional waste.
Select a water pressure that is suitable for removing major dirt from the surface being treated.

The product must be convenient to use, and therefore you should not resort to using large parts. If you live in an area where power is often cut off, it is advisable to provide alternative source power supply: equip the equipment with a rechargeable battery.

A device of our own production is capable of washing away contaminants of varying complexity from any surface, from any object. Even the most stubborn dirt stains will be removed without any streaks or residual dirt. The big advantage of the installation is the inability to damage the surface being treated during the cleaning process. Listen to the advice of experienced specialists - save time and money by creating useful household appliances with your own hands.

It is necessary to ensure that the car is clean so that accumulated contaminants containing aggressive chemical compounds do not destroy the paintwork and metal parts cars. To avoid wasting time and money visiting a car wash, you can design a high-pressure washer yourself.

1 How a high pressure washer works - design and other details

The advantage of a high-pressure washer is that the car body, engine compartment and bottom can be washed of dirt with a directed water jet. Such devices are installed on professional car washes and cost a lot of money. An excellent alternative to the device Karcher can become a homemade sink. The principle of operation of a high pressure washer is the same as that of a regular car wash.

First, air is pumped into the reservoir containing the water using a pump or pump. This creates excess pressure in the water container. Water is supplied outward through a rubberized hose when the trigger of the watering gun is pressed. A pump is needed to pump air into the tank. You can use a car or plunger pump. The convenience of the plunger is that it is a metered type hydraulic device. According to the selected proportions, the plunger unit mixes water and detergents, and then delivers the mixture under high pressure.

A homemade high pressure washer has a number of advantages:

the parts necessary for assembly can be purchased in stores or improvised materials can be used;
assembles quickly and easily;
easy to use at home;
it is possible to increase functionality by installing additional equipment;
the main advantage is low cost compared to professional analogues.

2 Selection of electrical elements - motor, pump and gearbox

The main element of the washer is the motor, which will supply a stream of water. You will need a powerful pump that could create a pressure of up to 150 atmospheres with a capacity of 15 liters per minute. During normal operation, it should use 80-90% of its rated power. It is advisable to select a pump with a power supply of 220 or 380 V. It can be made from a car compressor or a compressor from a refrigerator. It will cost less, but performance will be lower.

When selecting a unit that supplies water, you need to pay attention to the materials from which it is made. It should have a high strength ceramic or metal piston. To make the design more durable, the head must be made of brass or bronze alloys. For a homemade car wash, a low power motor of 200-200 watts is suitable. It is better to choose a single-phase motor: it is safer to connect and it is more economical.

A gearbox and a condenser can be included in the car wash design. Capacitor block increases the number of revolutions, which will increase productivity. Installing a gearbox in the form of a belt drive with one stage will make it possible to balance the load and speed between the pump and the motor. To connect the motor and pump, you must purchase a coupling that will ensure the safety of these units. It is better to buy a soft coupling, with which you can compensate for small deviations between the shafts.

3 Additional materials for a homemade sink

A necessary element is a container to hold the water that will be used for washing. It should have a volume of from 5 to 30 liters so that you do not have to fill it often. You can use a plastic canister or bottle as a container. You should pay attention that there are no seams on its bottom. At the inlet or outlet of the tank, you can install a filter in the form of a fine mesh, which will protect the pump from debris.

Hoses should be selected plastic or rubber with reinforcement, about 5 meters long and with an average diameter. Connections must be securely sealed. This is ensured with the help of clamps and sealant, which is applied at the joints. It is desirable that the design be dismountable and repairable, so threaded connections should be used whenever possible.

Water is supplied through the gun by pressing the trigger button. When choosing a pistol, make sure that the key operates smoothly, without jerking. To facilitate the washing process and create a stream of water of a certain shape, you need to purchase various attachments: rollers, brushes of different hardness, sprayers. All installation parts are mounted on a frame made of round and profile pipes. For ease of transportation, wheels can be attached to the lower tubes. You should also provide stops for fixing the installation and handles for moving.

If you need to wash your car at a low temperature, you can make your own foam generator. Using such a device, you can evenly apply fine-grained foam from the washing solution onto the car, which allows you to thoroughly wash the surface from dust and adhering dirt.

To obtain foam, water mixed with detergents, is sprayed by a stream of air that passes through installed channels, and then mixed with a foaming tablet in a special block. The flow is regulated using special plates.

4 Features of manufacturing and operation - assembly in 4 steps

Having prepared all the necessary components of the mini-wash, we combine them into a single structure:

First, we prepare a reservoir for connecting the pump and filling in the washing liquid. In the lid of the prepared container we make a hole for a nipple through which the pump will pump air and water with detergents will be poured. If there are gaps, they need to be treated with sealant.
Next, at the bottom of the container we prepare a hole for connecting a watering hose with a gun. We fasten the coupling from the inside and perform a thorough sealing.
When the tank is ready, we fix the main installation to it using soft connections. We seal all connections using a special sealant.
We draw from below watering hose with a gun and check the functionality of the car wash.

For safety reasons, the system must be grounded. To check, turn on the installation to the mains. In this case, you need to make sure that no water gets on the wires. If the assembly is done correctly, then after pressing the trigger, a powerful stream of water will begin to flow from the gun. If there is no pressure, it means the seal is broken, you need to check all connections.

In order for the installation to serve you for a long time, you need to follow a number of rules when using it:

Before each use of the car wash, check the connections for tightness.
You should not use high water pressure very often, as this puts a large load on the pump and leads to rapid wear.
For efficient work For mini-washes, it is advisable to use various attachments.
If filters are installed at the outlet of the tank, they must be cleaned of accumulated dirt and debris after using the unit.
To protect against voltage surges, the installation should be equipped with a battery.
