The cleanliness of the car is not only an aesthetic indicator, but also protects the product from negative environmental factors. Indeed, in the stuck and dried dirt may contain aggressive elements that damage the paintwork. Also, long-term and regular pollution of the body can lead to irreversible damage to the metal, up to through corrosion on individual elements.

In this case, it saves regular visits to car wash or home water treatments. But in the second case, it is necessary to buy a washing device or a car wash should be made by hand from improvised means. Prices in stores mostly start with 5 thousand rubles. The upper threshold can not stop at 20 thousand. Therefore, we will do independently.

Making washing at home

Pump and electrical part

The main part of any water supply unit is a pump. For our product, it will need a powerful enough, capable of developing pressure at least up to 150 atmospheres. Selecting the finished pump, it is necessary to consider the materials from which the working units are made.

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

In this case, the head of the block is recommended to select from brass or bronze alloys. This design is more durable. Its resource between repairs is quite high. A speed of 15 l / min will be sufficient for the pump.

It is desirable to select the electric motor with a voltage of 220 V. Reliable start-up is provided with an additional capacitor unit. Higher speeds for greater productivity.

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

Consumers of 2-3 kW and rotation up to 2000 r / min are considered optimal.

Rotation gear

Constructed high-pressure washing with their own hands must have the necessary safety elements in the chain to save important components. Such a link is a coupling connecting the pump and the engine.

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

You can also install a belt drive with one stage. This gearbox will balance the speed and load between the engine and the pump. The gear ratio is selected based on the required output parameters for the frequency of rotations.

Tank and Performance Controller

Mini sink should be equipped with a sufficient capacity for water. Suitable tank, which can additionally be powered from a permanent water source: a water tap, a deep-water well or a small water tower.

What to do from washing

At the entrance to the tank it is desirable to install coarse and medium filters. So, unnecessary litter will not fall 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 tank. The process will be more efficient.

The performance regulator is usually combined with a pump with a discharge valve that redirects unused pressure back to the tank, reducing the load on the pump.

External elements

All units are mounted on a frame made of shaped or round curved pipes. Often a pair of wheels is attached to the lower tubes to help transport the unit. Fixation stops and a handle are also installed so that the entire structure can be moved.

The appearance of washing your own car wash

For high pressure hoses, you can use plastic or rubberized reinforced hose. It is imperative to ensure the tightness of the connections with the help of quality clamps or hydraulic termination.

The design should be collapsible and maintainable. Therefore, it is desirable 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 has a visual resemblance to a gun at a gas station. A jet of water is formed only after pressing the key. This method helps to save the prepared working fluid with consumable additives. You can simply buy a gun at any hardware store.

The operation of the wash, made by hand

Parts for washing assembly

When operating, you must follow a few tips:

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

Car Wash Generators

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

The process of foaming home foam generator

Foamer for washing their own hands can be made even in the garage. You need to be patient and blanks of all nodes and elements.

The principle of operation of the foam generator

The device performs two main functions in the process of washing a car:

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

Homemade foam generator

To perform this process, a jet of water mixed with car cosmetics (shampoo or other specialized preparations) is sprayed with the help of a stream of air passing through the established channels, and together form a coarse foam.

After that, 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 thin spray jet, distribute the working foam in all the irregularities of the outer part of the body.

The difference between homemade equipment and professional

The quality of professional washing with the help of a foam generator can be higher than when using a device made by yourself. There are several criteria for this that determine the final result.

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

When using professional sinks apply specialized industrial shampoos.

Also, professional equipment allows you to pump a significantly greater fluid pressure than that which can be achieved in garage conditions. Due to this, the consumption of detergent 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.

Independent manufacture of foam generator

Making the foam generator will require the creators to stock up on a set of keys, a grinder, a pre-purchased repair kit with spare parts for a professional installation, consisting of a nozzle, a pistol, a compressor, and a flushing hose.

The principle of the car wash

In addition to these elements, you must take an inch pipe about 70 cm long. From it you need to make a filter. To do this, fill the cavity with pieces of fishing line. It is desirable to apply it of different diameter, it will be more efficient to form foam.

After packing, you need to install metal filters on both sides in order to avoid pieces of fishing line in the container with shampoo.

The principle of operation of the foam generator

Next on both ends of the pipe are threaded plugs. Now a T-shaped transition is screwed to one of the plugs. The compressor is screwed to such a transition, and the hose from the tank with liquid is screwed to the second thread. The free end of the tube with fishing line will be the outlet for the foam. To it through the fitting is attached a hose for spraying the finished foam.

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

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