Homemade wheel wash. How to make a high pressure washer with your own hands? Device Specifications

In the modern world, every family has a car, and not just one. Whether domestic, whether foreign - they all require permanent care. Some spare part has deteriorated - you need to change it, a flat tire - pump it up, a window has broken - insert a new one. And, of course, be sure to wash the car. Washing your car is not just about keeping your car clean. If you do not wash it, you can earn a fine from employees of the state traffic safety inspectorate. If you do not wash, then under the mud stain, the paint will soon be erased and the body will begin to rust. If you do not wash the interior of the car, it may be fraught with various diseases respiratory tract and allergies.

Considering all the above nuances, the conclusion suggests itself: car washing is a mandatory procedure for any car.

Do-it-yourself homemade karcher - the best option for washing a car

Choosing a way to wash your favorite car is up to the car owner himself. Someone can pick up a rag and a bucket, someone can go to a car wash. But perfect option is to make a homemade karcher. It can be done by investing a certain amount of money, or it can be made from improvised means without investing money in it.

Of course, a home-made Karcher will differ from the branded one, but it will fulfill its main purpose.

Advantages of a home-made device: low price, compactness, the ability to flush out dirt from any gap, autonomy, does not require electrical power, you can always carry it with you.

Karcher?

There are many ways to do it.

First way. The main mechanism of the future Karcher is taken - the compressor. It can be taken from any equipment that is no longer used on the farm. The mechanism is attached to the fitting with a hose. A brush is taken, to which it is attached necessary in order to regulate the power of the water supply. A brush with a tap is also attached with a hose. When fastening, you will need to use rubber gaskets, FUM tape, hermetic glue. The hose, on the other hand, is fixed in a container into which more than ten liters of water can be poured. The simplest homemade karcher from the compressor is ready to use. You can make a more automated method that will connect to the mains or cigarette lighter in the car.

The second way. A canister is taken, where you can pour more than twenty liters of water. A compressor from the car is attached to the inlet brass nipple from the tire. The hose is attached to the gun (you can buy it at any garden store). The length of the hose is at least six meters. Diameter 16 mm. When fastening, rubber flaps, clamps and nuts are used.

The effectiveness of a homemade Karcher

The efficiency of the Karcher depends directly on the selected engine (compressor). It must supply a high pressure of water, otherwise the manufacture of a home sink will go cold. A homemade karcher should consist of a durable case made of metal or thick plastic.

The brush on the hose is selected different: from hard to soft. You can use rollers and sprayers.

In any case, using a homemade Karcher for more than three hours is undesirable. Since this can lead to its rapid failure.

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

– cylinder diameter and piston stroke?;

- the ratio of the lever arms ?, one shoulder if I understood correctly 35 mm, and the second ?;

- the maximum pressure that the compressor develops?

And yet -Lefty, I did not understand about 160 atm and the volume of the sound. 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 percussion 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 a specialist in hydrodynamics.

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

Sincerely, Vladimir

Connecting tube too long - large dead space

It is not advisable to make an outlet on the side (in such a design), see the previous paragraph.

Yes, I would also seal the HP cylinder

The rest can be seen from the picture.

I almost forgot: at the outlet (near the pressure gauge) a bypass valve is required

tank compressor high pressure!? Who knows what?

A couple of months ago I saw one at the market, held it in my hands. The seller asked for about $ 40, did not buy, 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 arrangement of cylinders of different diameters. The drive is brought to the splines of the crankshaft, compactly.

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

1 drive power;

2 Rated crankshaft speed;

3 Upgradable?

Regards, Oleg

The compressor is not an AK150, if so, it was also used in the T80 for pumping cylinders up to 150 atm. Design 3 step, one cylinder with 1 degree, the second 2 steps. I'll try to find the exact specifications.

High pressure pump


Do-it-yourself high-pressure pump Since I did not see the clutch cylinder, I also understood little in the diagram. Therefore, the following questions arose: – cylinder diameter and piston stroke?; -

DIY high pressure washer

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

Such devices are usually installed at car washes and cost a lot of money. The Karcher pressure washer 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 a great alternative to professional Karcher devices, which you can assemble yourself from improvised means.

Industrial pressure washer

What you need to make

To make a Karcher pressure washer, you need to find suitable materials. You can use improvised items or purchase new ones in the store. So, to create a minisink you will need:

  • Water tank. The container will hold water that is used for washing. The tank should have a capacity of about 5 liters, otherwise you will have to constantly replenish the car wash near the water source. You should not choose too large a container, as the sink will be very heavy. An old plastic canister or bottle can be used as a water reservoir. When choosing a tank, make sure that there are no seams on the bottom of the tank.
  • Pistol for irrigation hose. This attribute can be purchased at any store. garden tools. In addition, the gun can be made independently.
  • Rubber hose from 0.5 to 4 m long.
  • Several hose connectors.
  • Sealant.
  • Using a simple set of inventory, you can assemble a Karcher type sink. Also, a home-made sink 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 pressure washer from a canister

The principle of operation of the device

Do-it-yourself high-pressure washing will work on the principle of conventional car washes. The water in it is supplied through a rubberized hose under high pressure. Air is pumped into the water tank by a car pump, which creates a overpressure. Water under pressure is supplied to the outside and is supplied when the trigger of the watering gun is pressed. Thanks to the strong pressure of water, with the help of a car wash, you can clean any surface.

In this case, the pump is used exclusively for pumping air into the tank. Replace the constant use of the pump, you can install a pump that allows you to manually raise the pressure. Also, plunger pumps are an alternative to automobile pumps.

Types of high pressure washers

Plunger pumps - modern devices, which belong to the hydraulic dosing type devices. The plunger pump independently mixes water in the selected proportions, detergents and feeds the mixture under high pressure. The disadvantage of installing such a pump is the excessive 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 a sharp knife in the lid of the canister, it is necessary to cut a hole that will be narrower than the nipple in diameter. After that, 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 water and detergents will also be filled.

Next, you need to prepare a system for connecting the canister to the watering gun. To do this, in the lower part of the canister, you need to cut a hole close in diameter to the coupling. The clutch is attached from the inside of the canister, you can start it with 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 scheme for compiling a homemade pressure washer

After the sealant has dried, you can begin to prepare the sink for work. To do this, plugging the fitting with your finger, you need to pour water into the canister. Also, any detergents can be added to the tank (specialized detergents for cars or household chemicals). The nipple must be connected to a car pump and gradually pump up the canister with air. During 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.

After completing these steps, a rubber hose is connected to the fitting, at the end of which a watering gun must be attached.

Setting up a homemade high pressure washer

Advice : You can check the correct assembly by pressing the trigger of the gun. If, as a result, a strong pressure of water began to flow from the gun, then the device was 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 is easy to assemble a minisink with your own hands, just follow the proposed instructions and buy a minimum set of equipment. As a result, within an hour, you can make a car wash, which, in terms of the quality of work, does not differ slightly from professional equipment in car dealerships.

Plunger water pump - distinctive features and applications in everyday life

Whether you decide to go into the car wash business or simply decide to keep your personal vehicle in perfect cleanliness, without resorting to after-sales services, then when developing a design for washing with your own hands, you cannot do without the use of high-pressure pumps. The best option in this case is to use plunger models that provide the necessary pressure in the system and differ high performance and price.

What is a plunger pump. Operating principle

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

Rice. 1. The device and principle of operation of the plunger pump

Differences between plunger pumps and piston pumps

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

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

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

  1. Unlike piston types, working surface which are deformed when in contact with a liquid at high pressures, in plunger pumps, a rigid and durable working cylinder does not change its shape at high pressures, which makes them indispensable when it is necessary to accurately dose liquids.

Rice. 2 Internal organization plunger pump

Thanks to their design features plunger pumps allow you to get the outlet pressure 3 times more than piston pumps with the same dimensions of the working chamber.

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 sector, they are used in the following industries:

  • In the chemical industry for pumping highly viscous substances and their precise dosing in the manufacture of chemical compounds that do not react with metal.
  • For supplying metered amounts 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 equipment with a hydraulic drive with a working pressure of up to 3000 bar, in the automotive industry in injection systems for diesel engines.
  • Plunger water pumps are widely used in car wash service centers.

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

Rice. 3 Appearance plunger pump

Main characteristics of plunger pumps

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

  • Power consumption. The consumed electricity directly depends on the performance and the pressure created, in this regard, plunger models have an advantage over other types due to the high efficiency of more than 90%.
  • Performance. It is determined by the volume of the working chamber of the pump, has the widest range from tenths of a liter per minute to ten thousand.
  • Operating pressure. The working 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 adversely affect its service life and performance. An engineering solution to this problem was the use of several plungers operating with a phase shift in one unit. The most common three-plunger models with a displacement of the working cylinders of 120 degrees, maximum amount plungers can reach 6. The implementation of this method is achieved by installing three eccentrics on the motor 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 do-it-yourself car washes.

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 of 15 l./min. It is quite difficult to find electric water pumps with an electric drive, usually an electric motor is connected to them.
  • Electric motor 2 - 3 kW. with a maximum speed of about 2000 rpm.
  • Reducer and V-belt transmission for connecting the electric motor and pump. It is possible to directly connect the pump shaft and the motor shaft with a soft coupling, which can compensate for the difference in the shafts and avoid damage in case of jamming.
  • Reinforced rubber or high pressure plastic hoses.
  • A gun with a nozzle and a handle that controls the water supply.
  • Water tank with feed 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 by directly connecting the pump to the water main.
  • For the convenience of working in the system, it is necessary to use the pump power control in tandem with an unloading valve that poisons excess water back into the tank.

Fig. 5 Do-it-yourself car wash accessories

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 fluids and accurately dose them. In everyday life, they can be used in systems designed for do-it-yourself vehicle washing.

How to make a high pressure washer with your own hands

What is a pressure washer?

Today, you no longer need strength and time to fight dried-on dirt and dust that has clogged into nooks and crannies, because every year new models appear on the market. high pressure washers. These devices are used to wash windows, cars, walls and doors of houses, barbecues and other items that are difficult to clean with a rag or brush. A strong water pressure copes with this task much more efficiently and saves money spent on washing a car in a service, while water consumption is also minimal. Therefore, it is useful for everyone to have such a sink in their arsenal.

Companies leading in the production of pressure washers - German Bosch, Karcher (hence the second name of 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 that creates the necessary water pressure. A pump or a motor is suitable (it is not necessary to buy a new one, take a working one from an old car), the motor is built into the sink body and must be connected to a power source. For the sink body (body), choose a durable material, thick plastic or metal. Even if you get a durable case, it's best not to use the sink for more than three hours in a row. This will disable the sink in a short time.

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

Internal pressure

The higher the pressure inside the housing, the stronger the jet of water from the hose, which means that the dirt lags behind more easily. Set the pressure carefully, because water can simply break a fragile car part or glass, 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 a hose, a turbo cutter. It will help wash tires, wheels, remove dirt accumulated in the cracks. You can use the mini-sink both outside and inside the cabin. If you are using a turbo cutter, you will need 160 bar pressure.

Electric pump

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

The material of the pump determines the wear resistance. The unfortunate option is a plastic pump, which will soon fail if used 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 sink

To wash worked properly follow these guidelines.

  • Be sure to check the performance of the sink before using it, this will save your time and health.
  • The filter installed in the car wash should be cleaned and replaced after each use.
  • If the washer uses electricity in operation, and the source is unstable, supply it with a battery.
  • Do not let children use the sink.
  • If repairs are needed, don't hesitate to do so. Replace failed sink components.
  • Update your device pads.
  • Protect your sink from temperature fluctuations.

How to make a karcher yourself

Although car washes have achieved widespread use, their cost is high. So, if you want to do your own washing, you need:

  • canister;
  • irrigation hose with a gun;
  • pump;
  • union;
  • cover for the canister;
  • tubeless wheel fungus;
  • rubber gasket;
  • coupling.

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

First stage. The choice of components.

The required volume of the canister depends on you and the purpose for which you use the sink: for passenger car enough five-liter canister. Drivers carry a car wash in their luggage, and therefore choose a case both in terms of volume and dimensions.

The irrigation hose must be strong and flexible, it must not be twisted or broken. Nylon-braided hoses are considered durable. A hose consisting of several layers is more reliable. Don't skimp on this part. There is only one requirement for a pistol: it must be firmly attached to the hose.

The pump can be foot or automatic. The high power of this pump will not be useful to us, so do not buy an expensive one. Use automatic pump much more convenient than a foot pump, because you do not have to constantly drag the pump from place to place and do unnecessary work with your foot. However decisive role plays the cost of the pump, automatic is three times more expensive.

Choose the fitting and the 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. Canister preparation.

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

Third stage. Cover collection.

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 fungus of a tubeless tire into it.

Fourth stage. Construction collection. Additional functions.

Tighten the canister tightly with a lid, connect the cord from the pump to the fungus, attach the free end of the hose to the hole made in the canister using a fitting. Homemade sink is ready. The principle of operation of such a sink is simple: using a pump, air is pumped into a canister of water (while the canister is not filled with water to the brim). Pressure up to 0.3 bar or higher if your canister can handle it. Under the influence of pressure, water shoots out of the gun when the handle is pressed.

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

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

Decide in advance for what purpose you use the sink. 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 an industrial 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 necessary, set the automatic water supply to save.

If it is possible to save on water consumption, then it is impossible to save on the purchase of washing components. To prevent the item from becoming dirty after washing, purchase special filters. You do not need an expensive filter that purifies water to a drinking state. The filter is needed to purify water, at least from litter, which will disable the sink.

You can even earn money by designing a pressure washer if you open a car wash. The main thing is that the sink you made works. Using the 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 is cost-free. The following is an instruction for creating a more complex model:

  • windshield washer motor;
  • irrigation hose with a 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 screws;
  • two-core electrical wire 5-7 meters long;
  • plastic sleeve;
  • power cable;
  • car wash brush

First stage. Create a hose.

We make a small hole in the bottom of one of the canisters. Inside a thick hose (diameter 10 millimeters or more), a thinner hose (up to 6 millimeters) and a two-wire wire are placed. Then the hoses fastened by us are inserted into the opening of the canister. A plastic sleeve is threaded into the free end of the hose. Further, a thin hose is attached to the washer motor, the wires are also attached 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 out of it with a shuttle. The motor is fixed on the second bottom of the canister, for these purposes it is used homemade clamp, which can be made from the remains of a cut canister. To do this, we need an M8 bolt and some sealant.

The wires are also fixed with 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 fixed. 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 pressure washer with your own hands What is a pressure washer? Today, strength and time are no longer needed to fight dried-on dirt and dust that has clogged into nooks and crannies, because

Often there are situations when the car is very dirty as a result of driving through polluted areas, but there are no facilities nearby to wash it well. For example, you went to the forest for mushrooms or berries, to the lake. Running into a pond with a bucket to douse the car, simultaneously rubbing the dirt with an old rag, is not an option. For such purposes, you can make a small mini-sink from the simplest tools at hand. It will be very compact and will easily fit in the trunk of any car without eating up extra space.

To understand how to make such a device, watch this video:

Necessary materials for the manufacture of a mini-sink:
- foot pump;
- capacity;
- union;
- quick disconnect valve;
- lid;
- fungus from a tubeless wheel;
- hose;
- watering head;
- rubber gasket;
- glue;
- adapter sleeve;
- sealant.


To get started, we take a container prepared in advance. It can be an ordinary plastic canister with a volume of at least 10 liters. Ideally, you need to use a large capacity container made of thick plastic or metal.

A fungus from a tubeless wheel is built into the container lid, sealed with a rubber gasket on glue. The gasket can be omitted if the hole for the fungus is made very accurately, which allows it to hold tight and tight.


A hole is made at the bottom of the container, into which, with the help of an adapter and silicone sealant fitting is attached.

The watering head is equipped with a quick-release valve that allows you to connect a hose. Also, such a valve connects the hose to the tank.


It is best to use a watering head equipped with five modes of operation: 3 rain and 2 simple jets. This will make its use more functional.


Principle of operation.
Using a foot pump, we pump air into the container so that the pressure is no more than 0.1-0.2 atmospheres, this will be more than enough. This creates excess pressure inside plastic canister, the air presses on the water in the tank. Now it will be enough to open the valve of the watering head for the water to flow out. Just do not overdo it with pressure so that your container does not burst.

Do you know that if your car is used to a high-pressure car wash, you can also provide it with such luxury without special stations with your own hands?

High Pressure Car Wash Features

Why are most special stations equipped with this type of washing? This is primarily due to the fact that this device you can wash the body, bottom, suspension, without making much effort. The main positive feature of a high-pressure car wash is that the directed jet of liquid easily and effectively washes away dirt from the surface of the object. This jet arises as a result of the operation of a high-performance pump, and forms its special tip.

Such a device will be useful not only for, but also for various household needs. So the intention to acquire your own system will also solve many everyday tasks, especially if you have a plot with spacious house. At least the washing of street communications and paths will be many times faster. There are many stores that sell this type of product, but it is much more pleasant to make a high-pressure car wash with your own hands. Moreover, this process is not particularly complicated.

Do-it-yourself high-pressure car wash - basic elements

The first thing to do is to purchase all the parts that will be needed to assemble the device. The most important and expensive part of a car wash is the pump. It must be of high performance. In addition, such a pump must develop pressure up to 100-200 bar. When choosing this part of the system, it is very important to pay attention to what materials it is made of. Most best option the working part of the pump should look like this: the pistons are made of strong metals either from durable ceramics, the block heads are cast from brass, and the crank mechanism liners need to provide a large area of ​​\u200b\u200bsupport.

Sometimes, to save money, a car wash is assembled from a compressor, such a system is made by hand, of course, faster, and the compressor in this situation acts as a water pump.

One more important detail is an electric motor. For a home car wash, it is best to use an electric motor with a power of 220 watts, that is, single-phase. This type of connection is safe and saves a lot cash. Some designs of car washes suggest the presence of capacitors and a single-stage gearbox. These items may make the device easier to use and also increase its lifespan, but they are not required.

We collect additional items for a car wash

When creating a car wash with your own hands, you will also need a clutch. This element connects the pump and the electric motor. For high pressure washer the best option there will be a use of a "soft" coupling, as it is able to compensate for the misalignment of the shafts along the axis. In addition, this type of coupling plays the role of a fuse in case the pump or gearbox jams.

An important element in the design is the water tank. Indeed, in order for the pump to work uniformly and uninterruptedly, it must receive a certain amount of water. As a container, most often, a tank is used, which is connected to water supply network. At the outlet, a special fine mesh is installed in the tank, which acts as a filter. This is necessary so that dirt does not get into the pump and does not interfere with its operation. The washing effect can be greatly improved by adding detergent to the tank.

A necessary element is also a pump performance regulator. The regulator in most cases comes with an automatic unloading valve. This device is necessary in order to redirect water back into the tank in case of need, in order to avoid overloading the pump. Also, in the process of creating a do-it-yourself car wash, a frame is used as the basis for all the details. In addition to it, high-pressure hoses are necessary for operation, as well as a gun with a nozzle. After all the elements are fixed on the frame and connected to each other, the work on the car wash can be considered completed and you can start using this device.

Today, buying a pressure washer is not financially expensive. You can find a good household option from 5000 rubles. The only problem is choosing good manufacturer. The most in demand on the market are Bosch, Shtil, Karcher and some others. However, there are also a lot of those who, for some reason, prefer to assemble a car wash with their own hands, they are fundamentally not satisfied with ready-made solutions. Moreover, in most cases, the manufacture of such a homemade product is not a rational solution.

On the one hand, a home-made sink will show that your hands are growing from where you need to, but on the other hand, it’s easier and perhaps even cheaper to buy turnkey solution. This eliminates the need to search for information on how to assemble your own washing machine from a compressor or from a high pressure fuel pump from diesel engines. Plus, you will need to find a gun (again, you need to buy it separately) and some other important structural elements. However, no one can guarantee that homemade device will be reliable, and washing with it will be of high quality. As a hobby homemade apparatus can be considered, but hardly as an alternative to a factory wash.


» From the material presented by the author, you will learn how you can independently make a full-fledged mini-high-pressure washer that works from a 12 V screwdriver battery, you can also connect to a car battery through an extension cord with alligator clips.

All motorists are well aware of how the car constantly gets dirty, especially in spring and autumn, in summer after rain. As the saying goes, "I just left the car wash and then bang torrential rain," many have come across this. Every time you don’t run into a car wash, periodically it runs like that in a month, and without that money is needed for spare parts for gasoline, etc.

It is allowed to wash cars only at specially equipped stations if you are in the city, but you still need to look for a way to save your money, and for this reason the author came up with a portable, compact mini-wash. It consists of a high-pressure pump, 8 atmospheres at the outlet, a blow gun, a flexible hose, a 12V screwdriver battery, wires and a body made of a conventional plastic bucket, a container for water intake is also needed (bucket, canister, bottle)

The advantage of this sink: water intake from any container, low consumption, the ability to work autonomously without an electrical outlet, thanks to the battery.

And so, let's take a closer look at what exactly is needed to create a mini pressure washer?

materials

1. high pressure pump 8 atmospheres
2. 12V battery from a screwdriver
3. plastic paint bucket
4. wires
5. switch
6. contacts
7. solder
8. water tank
9. hose
10. jet from the Zhiguli carburetor
11. gum
12. bolts
13. nuts
14. washers
15. crocodiles

Tools

1. drill with cone drill
2. stationery knife
3. screwdriver
4. soldering iron
5. pliers

Step-by-step instructions for assembling a mini pressure washer with your own hands.

First, we check the operation of the pump (the author ordered it from China), we connect the hoses, there will be 2 of them, that is, one for water intake, and the second for feeding into the gun. We unscrew the blue clamp and put it on the hose.

Now we twist and the whole connection is tight, the hose has nowhere to go.

Connect the hose and secure with a clamp.

Now Attention! The blow gun in the kit has nozzles, but the holes in them are a little too big, in order to reduce the diameter of the outlet, the author does the following, namely, unscrews the nozzle.

Instead of a native nozzle, a jet from a Zhiguli carburetor is screwed in; it fits perfectly on the thread.

Everything is now much smaller in the gun opening, which will contribute to the creation of a strong compact jet.

Such a switch is also inexpensive and can be bought at any specialized store.

The master soldered wires with contacts to the battery of the screwdriver, doing this with the expectation that the solder did not interfere with the connection of the charger and the battery could be recharged.

The wires are fixed with electrical tape.

Also, the wires practically do not interfere and the battery can be freely connected to the screwdriver itself.

And together the circuit is connected through contacts (father + mother).

After that, the master proceeds to assemble all the details of the mini-sink in the body of a plastic bucket, for which he drills 4 holes in the wall of the bucket using a drill with a conical drill.

The pump is wall mounted.

Tightened with 4 bolts and nuts.

At the bottom of the bucket, a mount was also made for installing a screwdriver battery, for which an elastic band and a bolt with a nut were used.

A mount is also provided for the extension cord, and it is located under the bucket lid.

Then holes are again drilled in the bucket for the gasket and hose connections.

As you remember, there are 2 hoses, one for inlet and one for outlet.

Everything fits compactly in this plastic bucket, the only thing is that the container must be taken separately.
