How to make a pressure washer. How to make a high-pressure washer with your own hands How a pump for a high-pressure washer works

Cleanliness of the car is not only an aesthetic indicator, but also protects the product from negative factors external environment. After all, stuck and dried dirt may contain aggressive elements that damage the paintwork. Also, long-term and regular contamination of the body can lead to irreversible damage to the metal, including through corrosion on individual elements.

In this case, regular visits to a car wash or home care can help. water procedures. But in the second case you need to buy washing device or a car wash should be made with your own hands from available materials. Prices in stores generally start from 5 thousand rubles. The upper threshold may not stop at 20 thousand. Therefore, we will do it ourselves.

Pump and electrical part

The main part of any water supply unit is the pump. For our product we will need it to be powerful enough, capable of developing a pressure of at least 150 atmospheres. When selecting a finished pump, it is necessary to take into account the materials from which the working units are made.

Preference should be given to products with a high-strength metal or ceramic piston.

It is advisable to select an electric motor with a voltage of 220 V. Reliable starting is ensured by an additional capacitor unit. Higher rpm will provide greater productivity.

You need to know that the pump is too high-speed a large number rpm can lose power at maximum operating speeds and is subject to intense wear.

Consumers of 2-3 kW and rotation up to 2000 rpm are considered optimal.

Rotation transmission

Constructable sink high pressure with your own hands must be in chains necessary elements security to save important nodes. This link is the coupling connecting the pump and the motor.

It is advisable to install a coupling that can compensate for small axial misalignments between the shafts.

It is also possible to install a single-stage belt drive. Such a gearbox balances the speed and load between the engine and the pump. The gear ratio is selected based on the required output parameters for the rotation frequency.

Reservoir and performance regulator

The mini sink must be equipped with sufficient water capacity. A tank that can be additionally powered from a permanent water source is suitable: a water tap, a deep-water well, or a small water tower.

What to make a sink from

It is advisable to install coarse and medium filters at the entrance to the container. Thus, unnecessary debris will not get into the pump and will not interfere with the operation of the entire system.

You can add car shampoo or other approved car cosmetics to the main water container. The process will be more efficient.

The pump's capacity regulator is usually combined with an auto-unloading valve, which redirects unused pressure back to the tank, reducing the load on the pump.

External elements

All units are mounted on a frame made of profile or round curved pipes. Often a pair of wheels are attached to the down pipes to help transport the unit. Stops for fixation and a handle are also installed so that the entire structure can be moved.

Exterior view of a DIY car wash

For a high-pressure hose, you can use a plastic or rubberized reinforced hose. It is imperative to ensure the tightness of the connections using high-quality clamps or hydraulic sealing.

The structure must be dismountable and repairable. Therefore, it is advisable to use threaded connections where possible.

Also, in places of contact with water (fittings, valves), low-corrosion alloys should be used: brass and bronze.

Car wash scheme

Direct water supply is carried out through a gun with a nozzle installed in it. It bears a visual resemblance to the gas station gun. A stream of water is generated only after pressing the key. This method helps save prepared working fluid with consumable additives. You can simply buy a pistol at any hardware store.

Operating a DIY sink

Parts for assembling the sink

When operating, you must follow a few tips:

• periodically it is necessary to inspect the connecting nodes and tighten them wrench threaded connections;
• filters installed in the device need to be inspected before each connection so that the throughput is not reduced;
• the electrical part must be grounded to avoid accidents during operation; for this, a cable with three copper cores is used, and the plug must have a grounding terminal;
• during the washing process, you do not need to fix the jet for a long time at one point on the machine body so as not to damage strong pressure paintwork.

Foam generators for car washes

A device for high-quality contactless washing is called a foam generator. With its help, you can completely envelop the car with small bubbles of a washing suspension and carry out high-quality cleaning of the surface from dust, dirt and adhered small particles.

The process of foaming with a home foam generator

You can make a foam generator for washing with your own hands even in the garage. You need to be patient and have all the components and elements ready.

The principle of operation of the foam generator

The device performs two main functions during the car washing process:

1. formation of fine-cell foam from prepared reagents;
2. uniform application of foam to the desired surface of the vehicle.

Homemade foam generator

To perform this process, a stream of water mixed with car cosmetics (shampoo or other specialized drugs), is atomized using a stream of air passing through installed channels, and together form a coarse foam.

After this, the mixture is passed through a block with a foaming tablet. Now this mass can be applied to the surface.

Plates that regulate the flow and provide a fine spray jet distribute the working foam into all irregularities in the outer part of the body.

The difference between homemade equipment and professional equipment

The quality of work performed by a professional cleaner using a foam generator can be higher than when using a device made independently. For this there are several criteria that determine the final result.

The main parameter is the size of the foam formed. Important characteristic is a homogeneous structure and minimum diameter bubbles.

When using professional washes, specialized industrial shampoos are used.

Also, professional equipment allows you to pump up significantly higher fluid pressure than what can be achieved in a garage environment.

Due to this, the consumption of cleaning materials is reduced.

But with all these factors, the result of self-washing turns out to be quite worthy, especially since the final price for one session speaks in favor of a homemade device.

Making your own foam generator Making a foam generator will require the creators to stock up on a set of keys, an angle grinder, and a pre-purchased repair kit with spare parts professional installation

, consisting of a nozzle, a gun, a compressor, and a flushing hose.

How a car wash works In addition to the listed elements, you must take approximately 70 cm long. You will need to make a filter from it. To do this, fill the cavity with pieces of fishing line. It is advisable to use it different diameters, so foam will form more efficiently.

After filling, you will need to install metal filters on both sides to prevent pieces of fishing line from getting into the container with shampoo.

The principle of operation of the foam generator

Next, threaded plugs are placed on both ends of the pipe. Now a T-junction is screwed to one of the plugs. A compressor is screwed to such an adapter, and a hose from a reservoir with liquid is screwed onto the second thread. The free end of the tube with fishing line will be the exit for the foam. A hose for spraying the finished foam is attached to it through a fitting.

You need to know that the quality of the resulting foam depends on the quality of the filling in the tube with fishing line.

You can achieve the desired result by changing the packing in the tube with fishing line. It is also possible to empirically select required length such a pipe and the texture of the fishing line.

Over time, high-pressure washers, primarily used for cleaning cars, have become increasingly widespread in domestic markets. Using a similar device, you can wash both the body part and the bottom and engine compartment. The undoubted advantage of this device is that a precisely directed jet is used to remove dirt from the surface of the car without the use of a powerful water pump. Do-it-yourself high-pressure washing is a very profitable idea, allowing you to significantly save money spent on periodic washing of the car. If we take into account domestic weather conditions, when at any time of the year there is dirt on the roads in any of the states of aggregation, then such a wash will pay for itself very quickly.

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

Basic principles of creating a sink

The main functional element of the sink is a pump that meets a number of requirements. Thus, it must show high functional performance per unit of time and operate in normal mode at a pressure of about 100-200 bar. Many plunger pumps equipped with an electric drive have these characteristics. When choosing a pump for your future washing, special attention should be paid to the material that became the basis for its working part. The best option is to use ceramics or durable metal for the pump pistons. The best option for making a cylinder head is brass. Robust components ensure long life service life.

The most profitable would be to purchase a pump with a working capacity of approximately fifteen liters per minute and a pressure of up to two hundred bar.

It turns out that such a pump in normal operation will operate at 80-90% of its maximum power.

Selection of parts for washing

Scheme of a homemade mini-wash.

When choosing an electric motor, you should pay attention to models that have a power supply of about 220 or 308 volts. If the high-pressure washer is used at home, it is advisable to use a single-phase 220 volt connection, as it will not entail additional costs and meets all safety requirements. To ensure optimal starting of certain engines, it is advisable to use additional capacitor units. Thus, the performance of the pump directly depends on the number of engine revolutions: the higher the frequency, the greater the performance.

But it is worth considering that working in this mode may negatively affect its resources. You should not give preference to too fast models. The maximum permissible rotation speed in this case is up to two thousand revolutions with a power of two or three kilowatts.

A high-pressure washer of a certain design allows you to provide the required pump performance when using a single-stage gearbox operating using a V-belt drive. The parameters of the pulleys (driven and driven) determine their gear ratio. The characteristics of the distance between the axes of rotation also play an equally important role in the operation of gearboxes.

A coupling is usually used to secure the pump and motor. Most suitable option- a soft coupling that can compensate for minimal axial misalignment of the shafts and act as a safety element in case the gearbox or pump jams.

Very important structural element Any sink has a container for storing water. In order to ensure maximum pump performance, it is necessary to use a certain volume of liquid. To do this, it is possible to use a special liquid tank that can be recharged from the water supply network. It is imperative to install a filter element (this can be an ordinary fine mesh) at the outlet point from the tank, designed to clean the liquid from dirt particles and prevent blockages from entering the pump. To enhance the cleaning effect, you can add a special or regular detergent to the liquid.

Hydraulic diagram of a car wash.

A do-it-yourself car wash must have a pump performance regulator in its design. Typically, this device is connected to an automatic unloading valve, which can, in a critical situation, redirect the liquid back to the tank so that no harmful load is created on the pump.

In order to fix all the structural elements of the sink, a special frame is used. For its construction, you can use hollow curved pipes. To ensure ease of use, you can fix a pair of small support wheels in its lower part and place a stop to give the structure stability during use. One of the ends of the frame can be equipped with a special handle designed for transporting the sink around the yard or garage.

The main structural element of a homemade sink is a water container. To ensure maximum pump performance, a certain volume of liquid must be used.

One of essential elements, which make up a DIY sink, are high-pressure hoses. A standard, not too thick, reinforced rubber or plastic hose can act as a sleeve. It should be taken into account that all structural connections of hoses must be made in compliance with tightness conditions, on the one hand, and not be afraid of corrosion and can be easily disassembled, on the other. To equip the fasteners, you can use fittings or threaded bushings made of hard aluminum alloys or brass. For this purpose, it is possible to install bayonet mounts.

When building a sink with your own hands, you must also select a gun equipped with a nozzle. Thanks to its shape, an imitation of the shape of the working jet is obtained. Actually, appearance it resembles the gun used at gas stations. To start dispensing water from the nozzle, press the handle. This is a definite advantage, as it allows you to save a large amount of water: liquid is supplied only when it is needed, when you press the gun handle. Making a shut-off valve with your own hands is quite problematic; the simplest and most reliable option would be to purchase a ready-made tip.

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

When installing a high-pressure washer, you must take care to create a grounding connection. For this purpose, a three-core flexible wire equipped with double insulation and a plug equipped with a grounding terminal are often used. It is worth considering that the power outlet also needs reliable grounding using a circuit.

It is necessary to periodically inspect all connections and fastenings and tighten them if necessary. The filter element of the tank should be regularly cleaned of accumulated debris.

It is not advisable to use a high-pressure jet of water too often - this will cause unnecessary stress on the injection pump and cause damage. paint coating car. It is recommended to apply pressure that can contactlessly rid the machine of the main layer of dirt on the surface being treated, and then use a brush to manually remove the remaining dirt.

How does a high pressure washer work?

Thanks to devices operating at high pressure in the range of 120-150 bar, you can remove dirt from almost any surface. You should be prepared for the fact that a small layer of plaque will still remain after such treatment.

Manual homemade car wash.

Any sink must have a device that regulates the nozzle. By adjusting the position of the nozzle, you can change the pressure or shape of the jet. The nozzle can be equipped with foam generators and additional mud cutters.

If you wish, you can design a sink with your own hands that can be fed not only directly from the water supply, but also from a special reservoir - for example, a barrel of water. To improve the pressure in the sink, you can place the barrel on a slight elevation.

In case of a power outage or using the sink far from sockets, you can equip the device not only with a water tank, but also with a powerful battery.

The undoubted advantage of sinks of this type is greater water savings, in contrast to manual washing.

Washing device

Car wash device.

There should be a motor inside the high-pressure washer that causes the rotation and opening of other parts - a valve, washer or sprayer. The result of its work is the unwinding of the washer and the movement of water through the sprayer according to a forward-return trajectory, as a result of which water enters the sprayer valve. The result of the action of many mechanisms is the formation of powerful pressure and water supply.

It is advisable to choose a body for washing from impact-resistant plastic. The same requirements apply to the hose connecting to the sprayer, since it will have to interact with strong water pressure.

Regardless of how durable the materials from which the sink is made, it is highly recommended not to use it for more than two hours at a time. An operating cycle that is too long can lead to rapid wear of the component parts and reduce the service life of the device several times.

If you equip the sink with additional attachments, it will be able to perform the functions household appliances. When using additional attachments, the washer can be used both for washing a car and for cleaning roofs, facades and floors.

Main parts of a pressure washer

A DIY sink consists of the following elements:

Scheme of a homemade mini-wash.

• durable wear-resistant body;
• engine running on gasoline or electricity;
• high pressure pump;
• containers for water and detergents;
• additional nozzles;
• water filters;
• hoses.

The operating principle of a homemade car wash is extremely simple. Once connected, water from a water supply or a special container enters the sink container and is pumped through a pump. In maximum load mode, the washer operates at a pressure of about 160 bar. For comparison, a stream of water from a regular tap is supplied under a pressure of five bar.

Homemade car wash.

The next step is to supply water through a hose to the gun with a nozzle. It is advisable to equip a pistol special nozzle, allowing you to change the nature of the water flow - from a concentrated jet to spraying. The nature of the water supply should be determined based on how the surface will be cleaned. For example, to cover large area(veranda area or car body) the best option there will be a fan stream. In order to remove fragments of stubborn dirt, it is advisable to use a point water supply.

Add-ons can include a nozzle with a rotating nozzle, a rotating brush and much more. The main advantage of using nozzles is contactless surface cleaning, which significantly reduces the risk of damage to the paintwork of the car body or decorative surface facade tiles.

When choosing parts for washing, you should not strive to achieve maximum power. A sink used at home can function normally at an operating pressure of 100 bar. Moreover, for a person who has not previously encountered such equipment, it will be problematic to operate a washer operating under high pressure.

Additional washing functions

Washing power diagram.

When designing a sink with your own hands, you can provide another additional function - heating the water. It will be a good option when using a sink in the cold season. Heated water copes much better with old contaminants.

Water heating can be ensured by installing a special burner inside the housing. The installation of additional elements affects the dimensions of the entire structure - if you want to equip a sink additional function, you need to choose a slightly larger case for this.

Sinks that are not designed to heat water are more compact and maneuverable to use.

In order to make a high-pressure washer with your own hands, you should think about choosing a power source for it. If there are no problems with the electricity supply, you can design an electric washer. If the washer needs to be mobile, it is better for it to run on gasoline.

It is worth thinking about the mobility of the structure - the sink can be either stationary or mobile. Mobile sinks are convenient to use for cleaning hard to reach places car body. For their construction, a longer hose and several wheels are used. Stationary structures are more suitable for use on an industrial scale and can be connected exclusively to the water supply.

Some craftsmen have come up with a way to attach a water stop system to the sink - when the user stops holding the gun handle, the water supply automatically stops. This innovation allows you to save a large amount of liquid.

When buying parts for washing, you should not save money - cheap models will not last long. It is very important not only to extend the service life of the sink, but also to preserve the surfaces being cleaned in proper form, to select high-quality water filters. There is a high probability that abrasive particles can penetrate into the pump with water, which can lead to destruction of the pump pump. The most profitable option is reusable filters.

Many people take on the task of creating a car wash with their own hands in order to make a profit - a car wash operating at high pressure can serve a considerable flow of cars. Many modern car washes work with such devices. What’s noteworthy is that such a car wash can be used to clean cars, as well as motorcycles, bicycles and components.

Step-by-step instructions for creating a sink

First of all, you should select the appropriate pump unit. If the sink will be used commercially, it is better to choose industrial units. Basic requirements: it must be a plunger pump equipped with ceramic pistons. The increase in service life is also accompanied by the presence of a crank mechanism.

An auto-priming valve must be connected to the pump. It is produced in two variations. The first type is a closed valve on the pump. After the gun closes, the system releases pressure and water begins to be pumped from the outlet to the inlet. It is advisable not to use such a device for more than three minutes. A valve with a bypass is more convenient to use. When the pressure is released, the liquid will flow through the collector directly into the container or directly into the sewer - depending on the type of connection of the sink.

AROS mini washing station.

There are two ways to connect the motor and pump to each other. If a motor with a full shaft is available, it can be directly coupled to the pump. In this case, the motor shaft will be located on the front bearing and create additional load on it. This will be the simplest and economical option. It should be taken into account that a do-it-yourself car wash with such an engine will have a short service life between repairs due to high starting loads. A situation may arise when it is not possible to remove the pump shaft from the engine. To avoid the development of such situations, it is advisable to install a soft start device in the sink.

Another option for coupling the motor and pump is to use a coupling. The clutch will act as a cushion, softening the shock that occurs during start-up. The coupling acts as protection against shaft misalignment. In order to reduce the starting load, you can use a smooth release mechanism: thanks to it, the power in the system will increase gradually.

The next step is for the sink to be mounted on the frame. The following steps are carried out sequentially with your own hands - installation of electrics, a gun with a nozzle and a high-pressure hose. It is very important that the pressure washer is installed according to the parts manufacturer's recommendations. It is necessary that the assembly sequence be strictly observed, the load exerted on the screws being tightened be taken into account, anaerobic clamps be used, and the like.

It is required that the sink be connected to the water supply with a hose that is at least seven meters long. This is the optimal length to smooth out pressure surges in the water supply system. If a do-it-yourself sink will be fed from a water tank (the capacity should not be less than thirty liters), it is advisable to use a hose with check valve. This part can increase the working pressure.

Today, washing a car is no longer a lengthy and labor-intensive task. A high pressure washer helps you get the job done much faster and more efficiently. In addition, these devices can be used for washing windows, doors and walls of houses, barbecues - in a word, objects that are not easy to clean with a brush and (or) rag. Water supplied under strong pressure copes well with these tasks and helps save time. But such a device is not cheap. Good wash costs from 150 USD. e., and the possibilities budget models very limited. The way out is to use a high-pressure washer with your own hands. Having such a device at your dacha is very useful.

Structure:

• The main part of the device is an electric motor that creates water pressure. A pump, not necessarily a new one, is suitable for this purpose.
• The motor is inserted into the device body and connected to the power supply.
• The housing must be made of durable material. For example, made of metal or thick-walled plastic.

Important! Even in this case, there is a limit on the time of continuous use of the sink. Do not use it for more than 3 hours at a time. The washer will fail in no time.

• If you buy several brush attachments, you can turn your homemade device into multifunctional device. In particular, by equipping the design with a water heater, you can use it as a steam mop or steam cleaner. The turbo mill helps to wash tires and remove dirt from even the most difficult areas.

Internal pressure

The higher the pressure inside the housing, the more powerful the water jet from the hose. This means that contaminants are washed away better. But the pressure must be set carefully, since water under pressure can simply break a car glass or leave dents on the body:

• The pressure on industrial devices is 150-170 bar.
• For a DIY wash, 100 bar is quite enough.
• When using a turbo cutter, higher pressure is required - about 160 bar.

Electric pump pump

From the right choice pump depends on how well your high-pressure washer, assembled by yourself, will work. The material used to make the pump determines its wear resistance:

• The most budget and unsuccessful option is plastic construction. The time of continuous operation of the sink in this case does not exceed 20 minutes.
• More expensive, but reliable pumps are brass. They are not afraid of corrosion.

Rules for the safe operation of mini-washes:

• Before using, check the device for functionality.
• After each use of the device, thoroughly clean the filter.
• If power outages occur frequently, equip the device with a battery.
• Keep children away from using the car wash.
• If you notice that some part is out of order, do not hesitate to repair it. Replace it with a valid one as soon as possible.
• Do not allow the air temperature in the room in which the device is located to fluctuate.

Making your own mini-sink

To make a car wash with your own hands, prepare in advance:

• Pump.
• Canister with a lid.
• Irrigation hose with a “gun”.
• Union.
• Coupling coupling.
• Rubber gasket.

These are parts for a future car wash. From Supplies you will need drills and sealant.

Important! Before you make a high-pressure washer, the question arises: what size canister should you choose? Practice shows that for ordinary passenger car A 5 liter canister is quite enough. This is quite enough for washing a car, and such a unit can easily fit in the trunk.

Some tips for choosing components:

• There are two requirements for an irrigation hose: strength and flexibility. The best option- These are products with braided nylon. Multilayer hoses are more durable and reliable. You shouldn't skimp on them.
• The pump can be used foot or automatic. The latter option is much more convenient, since you don’t have to carry the pump from place to place and use your foot at the same time. The limiting factor is cost: an automatic pump costs three times as much.
• There are no special requirements for the fitting and coupling. The main thing is that they are in strong contact with each other.

Important! It is desirable that they be made of the same material - plastic or metal.

• To connect the device to the water supply, you will need a long (5-7 m) hose. This is enough to smooth out the pressure. If the water source is a container of at least 30 liters, it is recommended to use a hose with a check valve to increase the operating pressure.

Body preparation:

• Drill a hole in the body (canister) that is sized to fit the coupling.
• Insert the coupling with the fitting into the hole.

Important! Don't forget to secure the coupling with sealant. This is necessary so that high pressure is maintained inside the canister and the coupling does not pop out during operation of the device.

• Now it's time to work on the lid. The lid will need to be made of hard and durable material. Attach a rubber gasket to its bottom. Make a hole in it and mount the fungus from a tubeless tire.

Final assembly:

1. Attach the cord from the pump to the “fungus”.
2. Attach the free edge of the hose with the fitting to the hole previously made in the housing.

The sink is ready! The principle of operation is this. The pump pumps water and air into the canister (no need to fill to the brim!). You press the handle of the “gun” and a stream of water hits under pressure.

Important! If you are going to use the car wash in cold weather, it is advisable to equip it with a water heater.

Can be used as a source of energy for the device.

A high pressure washer is a highly efficient unit used for professional cleaning of cars - paintwork, engine compartment, rims, other elements.

The device is necessary to create high pressure, strong water pressure, which ensures cleaning of surfaces and structures.

This type of tool is used by service technicians, but a homemade high-pressure car wash with your own hands will cope with the task just as well.

What parts are needed to assemble a car wash?

Setting up a mini-wash is a simple process. The work begins with the selection of parts for subsequent assembly of the structure. The working part must be assembled from high-quality, proven materials. The components, with the exception of the pump, do not have to be new. But the serviceability is first checked to avoid breakdowns.

1. The pump or motor that creates water pressure is the main part. When choosing, pay attention to performance and the ability to create pressure. For infrequent use, at home, a pressure of 100 bar is sufficient. When installing additional equipment, nozzles require up to 160 bar. Average figures vary between 100–200 units.
2. The electric motor is the power source of the system. At self-assembly It is recommended to choose single-phase devices with a potential of 220V. They are safer and more accessible.
3. Coupling – necessary to connect the pump and the power plant. It is preferable to have models that can perform the functions of a fuse and balance the misalignment of the shafts along the axis.
4. Housing, water container – ensures a uniform supply of water masses. Tanks made of durable plastic or metal are used.
5. The frame is the basis for securely fastening the elements. Often additional wheels are installed at the bottom for mobility and ease of use.
6. A gun with a nozzle and hoses are required to supply water. The hose chosen is high-quality, reinforced.
7. Nozzles - used to change the nature of the water flow. There are many models used to solve specific problems.

You should not skimp on the quality of parts - this will affect the performance of the device.

To homemade sink high pressure was assembled correctly with your own hands, other components will also be required.

Additional items:

• filter element - a fine mesh that prevents the entry of dirt and debris particles;
• capacitor, single-stage gearbox - optional components, but they make it easier to start, improve the quality of work, and productivity;
• – can be used as a pump, base for a car wash, greatly simplifying assembly;
• performance regulator, unloading valve - parts that ensure safety and efficient operation;
• clamps or hydraulic sealing - will make the connections airtight;
• elements in contact with water are selected from corrosion-resistant alloys.

Having completed the collection of spare parts, you can begin fastening the elements and installing them on the frame. It is important to maintain the ability to repair equipment by more often using threaded connections.

During the assembly process of a car wash, there are several important points that determine the safety of further operation and the absence of malfunctions.

The frame is the basis of the entire structure:

• it is planned to manufacture a system with optimal sizes what are they selected for? suitable pipes– round, curved;
• in addition to the wheels, it is advisable to install clamps at the bottom;
• handle - makes transportation easier.

Grounding – safety element:

• a three-core wire is selected;
• you will need a plug with a grounding terminal;
• The socket is grounded.

After preparation, several main steps are performed:

1. Electrical equipment is installed on the frame, including a motor, pump, and other structural elements.
2. A gun with a nozzle is attached, supplying water after pressing a special button. Such devices are used by professionals, but they can also be easily purchased in a store.
3. A high-pressure hose is being installed.

After completing the assembly, connect to the water supply. A 7 m long hose is suitable for this.

How to avoid unexpected device breakdowns

When thinking about how to make a car wash with your own hands, it is advisable to ensure optimal operation, preventing the need for subsequent restoration.

Important points installation usage:

• before starting, all connections and fastenings are checked;
• the filter element needs to be regularly cleaned to remove dirt;
• You should not use equipment frequently full power;
• Installing a battery will protect the device from power surges.

If you assemble the device yourself, subsequent restoration and replacement of rubber rings and seals will not cause any difficulties.

A car wash is used to remove debris, dirt from the car body and other parts. A foam generator allows you to maximize the quality of cleaning. It's also easy to make yourself.

A small amount of tools is selected:

• roulette;
• knife;
• Bulgarian;
• wrenches;
• pliers.

When thinking about how to make a foam generator for a car wash with your own hands, you should choose and suitable materials, parts for assembly.

Basic moments:

1. A pipe with a length of at least 50 cm is required. It is filled with polyethylene sponge for subsequent foam formation.
2. A filter is installed in the form of a mesh to prevent filler from getting into other units.
3. One edge of the pipe must be plugged and a tee must be installed to subsequently secure the foam concentrate tap.
4. Using a fitting, connect the pipe and hose intended for foam.
5. A valve is connected to the other end, providing a flow of compressed air masses.

The characteristics of the foam that will be obtained as a result of the operation of such an installation are determined by the length of the pipe used. The density of filling the surface with a washcloth requires attention. For filling car cosmetics, a container that can withstand the pressure exerted by the system is suitable.

A car wash and a foam generator are useful units that simplify the process of car care. They can easily cope with loads in home use, perfectly replacing factory tools.

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. - an excellent alternative to professional ones, which you can assemble yourself from improvised means.

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:

How the device works

It will work on the principle of conventional car washes. The water is supplied through a rubberized hose under high pressure. Air is pumped into a container of water by a car pump, which creates excess pressure in the tank. 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 this case, the pump is used exclusively 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.

Plunger pumps - modern devices, which belong to hydraulic devices of the metering type. The plunger pump independently mixes water in the selected proportions, detergents and delivers 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 a sharp knife, you need to cut a hole in the lid of the canister, which will be narrower in diameter than the nipple. After that, after inner side The lid is threaded through the nipple.

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 that is 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.

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 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.

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.
