A modern driver does not have to worry about having to deal with dirt that has become clogged in the corners or stains that have firmly eaten into the surface of the car. New models of car washes are produced annually, and the scope of their use is not limited to car washing. It can also be cleaning windows, washing barbecues, doors and walls, and other objects that cannot be tidy with a regular brush or rag. Such tasks are within the power of the powerful pressure of water, but the cost of a decent apparatus starts from 10 thousand rubles, so a do-it-yourself high pressure washer began to be in demand.

The design of any washing machine is represented by the following functional units:

1. The engine is an indispensable foundation for the stable operation of the pump. The electric option is more common, but self-contained units can also be found. In the latter case, the engine can run on diesel or gasoline.
2. The key purpose of the pump is to pump water from an appropriate reservoir or centralized network. To use the latter, you will need additional hoses.
3. The pump is responsible for pumping fluid pressure, the durability of which directly depends on the material used in its manufacture. Plastic options are the last thing that should grab your attention, as long-term use (more than 20 minutes per session) will quickly disable it. Brass is the most reliable material due to its lack of tendency to corrosive processes. Purchased sinks are rarely equipped with this option, so you have every chance of making a unique and ultra-efficient machine yourself.
4. The motor fuse is responsible for monitoring the operation of the unit. When a critical point of water pressure is identified, the rotation of the engine is blocked. An example of this kind of situation is the accumulation of liquid inside due to a blocked hose during the operation of the sink.
5. Filters are the main protective elements that protect the device from mechanical damage due to the ingress of sand and other large foreign particles.

DIY washing

Let's consider how to make a high pressure washer with your own hands and what factors to consider before buying the constituent elements. The acquisition of structural parts is the first step.

The pump will take the largest amount from your budget, but the importance of this element is difficult to overestimate. Focus on high performance options. The optimum is the development of pressure up to 100-200 bar. For the manufacture of pistons, ceramics or other durable materials must be used, brass for the head of the blocks, they must be made by casting. A wide area of ​​support should fall on the liners of the crank mechanism.

Do-it-yourself car wash from a compressor is the option that saves money.

Its self-production is simpler, the compressor is a successful and effective alternative to a water pump.

Choosing an electric motor

It is better to choose a single-phase electric motor when it comes to household use. Connecting to a 220 V network allows you to protect yourself from unnecessary problems and keep your finances intact.

Reducer and capacitors

A single stage gearbox and capacitors can be used to improve ease of operation. The aforementioned components of the structure are not mandatory, but they can increase the resource of the apparatus.

Do not forget to buy a coupling that will be used to connect the engine to the pump. The soft clutch is what should get your attention, as its function is to compensate for possible misalignments. It is also an alternative to a fuse if problems arise with the pump or gearbox.

Water tank

A specific volume of water ensures that the pump operates in a uniform mode, and an appropriate container is needed for water. This can be a canister or a tank for which it is necessary to provide a connection to the water supply network. Do not forget to place a filter mesh at the outlet, its functions will be limited to filtering the incoming water.

The addition of active detergent substances to the tank will significantly increase the washing efficiency.

Regulator

The regulator, which is responsible for pump performance, is often equipped with an automatic unloading valve that directs the water back in the event of dangerous circumstances for pump operation.

Other details

Use a frame as a base. Also come in handy is a nozzle gun that is fixed to the hose and high pressure hoses.

Car wash assembly is limited to fixing the listed elements on the frame and connecting them to each other.

Design options

Knowing the features of the technological process of assembly and packaging, it is worth thinking about the design features of the future device:

1. Consider in advance what kind of power source will be acceptable for you. Choosing a fuel, you do not have to worry about the possibilities of transporting and moving the device. When giving preference to electricity, provide uninterrupted access to the source. Free movement of the unit is unlikely to be possible, but spending on expensive gasoline will be excluded from the list of problems.
2. Before starting work, decide on the operational goals. The compact unit with a long hose is ideal for washing car wheels and windows at home. If you are aiming at a production scale, the ability of the device to move will not be so important, so the sink can be immediately made stationary and connected to the water supply.
3. If you intend to save money, set up the automatic water supply. You can afford to save on water, but don't do it for structural elements.

Operation and maintenance

A good car wash service is directly dependent on the following recommendations:

• change the filter after each use of the washer to maintain the flow rate at an optimal level;
• before activating the unit, make sure that it is working properly;
• exclude children's access to such equipment;
• purchase a battery if the power source is unstable;
• elements that are out of order, change immediately;
• ground the electrical part with a cable with three copper conductors;
• the plug must have a grounding terminal;
• do not use the device for more than 3 hours in a row, even if you made it from the most durable materials;
• do not fix the jet in one zone on the surface of the car for too long, otherwise you risk damaging the paintwork;
• despite the pressure inside the case of 150-170 bar in the case of store versions, with self-production, 100 bar will be enough;
• if stains are not removed under a pressure of 100 bar, it is better to get additional brushes or a turbo milling cutter in the form of a hose nozzle.

conclusions

There is nothing complicated in making a car wash yourself. Study the device and how it works, turn on your imagination, plan the necessary purchases and start assembling. Remember to check the fasteners periodically and tighten them if necessary, as they may loosen during use.

The cleanliness of the car must be monitored so that the accumulated dirt containing aggressive chemical compounds does not destroy the paintwork and metal parts of the car. In order not to waste time and money visiting a car wash, you can design a pressure washer yourself.

1 How the pressure washer works - construction and other details

The advantage of a pressure washer is that the car body, engine compartment and bottom can be cleaned from dirt with a directed water jet. Such devices are installed in 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 pressure washer is the same as that of a conventional car wash.

First, air is pumped into the reservoir in which the water is located using a pump or pump. This creates excess pressure in a container with water. Through a rubberized hose, water is supplied outside when the trigger of the spray gun is pulled. A pump is needed to pump air into the reservoir. You can use an automobile or plunger pump. The convenience of the plunger is that it belongs to the dosed-type hydraulic apparatus. According to the selected proportions, the plunger unit mixes water and detergents and then delivers the mixture under high pressure.

A homemade pressure washer has several advantages:

• parts necessary for assembly can be purchased in stores or adapted materials at hand;
• 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 counterparts.

2 Selection of electrical components - motor, pump and gearbox

The main element of the sink is the engine, which will supply a jet of water. You will need a powerful pump that could create pressure 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 desirable to select a pump with a power supply of 220 or 380 V. It can be made from an automobile compressor or a compressor from a refrigerator. It will be cheaper, but the performance will be lower.

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

The design of the car wash can include a reducer and a capacitor. The condensing unit increases the number of revolutions, which will increase the productivity. Installing the 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, it is necessary to purchase a coupling that will ensure the safety of these components. It is better to buy a soft coupling, with which it will be possible to compensate for small deviations between the shafts.

3 Additional materials for homemade washing

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

Hoses should be selected from plastic or rubber with reinforcement, about 5 meters long and an average diameter. The connections must be securely sealed. This is achieved with clamps and a sealant applied to the joints. It is desirable that the structure is collapsible and maintainable, therefore, threaded connections should be used whenever possible.

Water is supplied through the gun by pressing the start key. When choosing a pistol, pay attention that the key works smoothly, without jerking. To facilitate the washing process and create a jet of water of a certain shape, you need to purchase various nozzles: rollers, brushes of different hardness, sprayers. All parts of the unit are mounted on a frame made of round and shaped pipes. For ease of transportation, wheels can be attached to the down pipes. You should also provide stops for fixing the unit and handles for moving.

If you need to wash your car at a low temperature, you can make a foam generator with your own hands. With the help of such a device, you can evenly apply fine-grained foam from the cleaning solution to the car, which allows you to qualitatively wash the surface from dust and adhering dirt.

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

4 Features of manufacturing and operation - assembly in 4 steps

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

1. First, we prepare a tank for connecting the pump and filling the washing liquid. In the lid of the prepared container, we make a hole for the nipple through which the pump will pump air, and water with detergents will be poured. If there are gaps, they must be sealed with a sealant.
2. Next, from the bottom of the container, we prepare an opening for connecting a garden hose with a gun. We fasten the connecting sleeve from the inside and perform a thorough sealing.
3. When the tank is ready, we fix the basic installation to it with the help of soft joints. We seal all joints using a special sealant.
4. From below we run a watering hose with a gun and check the performance of the car wash.

For safety reasons, the system must be grounded. To check, turn on the installation to the power grid. In this case, you need to ensure that no water gets on the wires. If the assembly is done correctly, then after pressing the trigger, a powerful jet of water will begin to beat from the pistol. If there is no pressure, then the seal is broken, you need to check all the connections.

In order for the installation to serve you for a long time, you need to follow a number of rules during its operation:

• Before each use of the car wash, check the tightness of the connections.
• It is not necessary to use very often a strong water pressure, as this puts a heavy load on the pump and leads to rapid wear.
• For efficient operation of a mini-sink, 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.

Car cleanliness is not only an aesthetic indicator, but also protects the product from negative environmental factors. After all, adhered and dried dirt can contain aggressive elements that damage the paintwork. Also, long-term and regular contamination of the body can lead to irreversible damage to the metal, up to perforating corrosion on individual elements.

In this case, a regular visit to a car wash or home water procedures saves. But in the second case, you need to buy a washing device or a car wash should be made with your own hands from improvised means. Prices in stores generally start at 5,000 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 a pump. For our product, it will need a powerful enough, capable of developing a pressure of at least 150 atmospheres. When choosing a ready-made 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 start is ensured by an additional capacitor unit. Higher rpm will provide more productivity.

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

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

Rotation transmission

A do-it-yourself high-pressure washer designed must have the necessary safety elements in the chain to preserve important components. This link is the coupling that connects 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 belt drive with one stage. This gearbox balances the speed and load between the motor and the pump. The gear ratio is selected based on the required output parameters in terms of rotation frequency.

Tank and capacity regulator

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

What to make a sink

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

Car shampoo or other approved car cosmetics can be added to the main water tank. The process will be more efficient.

The capacity regulator is usually combined with an auto-unloading valve on the pump, which redirects the 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 bent pipes. Often, a pair of wheels are attached to the lower pipes to help transport the unit. Also, stops for fixing and a handle are installed so that the entire structure can be moved.

The appearance of a do-it-yourself 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 joints using high-quality clamps or hydraulic sealing.

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

Also, in places of contact with water (fittings, valves), low-corrosion alloys must 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 a pistol at a gas station. A jet of water is formed only after pressing the button. This method helps to save prepared working fluid with consumable additives. The gun can simply be bought at any hardware store.

Do-it-yourself sink operation

Sink assembly parts

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;
• filters installed in the device need to be inspected before each connection so that the throughput does not decrease;
• the electrical part must be grounded to avoid accidents during operation, for this, a cable with three copper conductors is used, and the plug must have a grounding terminal;
• during the washing process, it is not necessary to fix the jet at one point on the machine body for a long time, so as not to damage the paintwork with a strong pressure.

Foam generators for car wash

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

Foaming process with a home foam generator

A DIY foam generator can be made even in the garage. You need to be patient and prepare all the nodes and elements.

The principle of operation of the foam generator

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

1. formation of fine-cellular 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 preparations) is sprayed using an air stream passing through the installed channels, and together they form a coarse foam.

The mixture is then passed through a foaming tablet block. Now this mass can be applied to the surface.

The flow control plates provide a fine spray jet to distribute the working foam to all the unevenness of the exterior of the body.

The difference between homemade equipment and professional

The quality of work of a professional wash with a foam generator can be higher than when using a device made by yourself. For this, there are several criteria 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 bubble diameter.

When using professional washes, specialized industrial shampoos are used.

Also, professional equipment allows you to pump significantly more fluid pressure than that which can be achieved in a garage. This reduces the consumption of cleaning materials.

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

Self-made foam generator

The manufacture of a 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.

How a car wash works

In addition to the listed elements, it is necessary to take an inch pipe with a length of about 70 cm. 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 of different diameters, so the foam will form more efficiently.

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

The principle of operation of the foam generator

Further, threaded plugs are placed on both ends of the pipe. Now a T-shaped transition is screwed to one of the plugs. A compressor is screwed to such a transition, and a hose from a liquid reservoir is screwed onto the second thread. The free end of the line will be the foam outlet. A hose for spraying ready-made foam is attached to it through a fitting.

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 fishing line. It is also allowed to empirically select the required length of such a pipe and the texture of the fishing line.

Today it is no longer necessary to waste time and effort to deal with dried-on dirt and clogged dust. Every year new modifications of pressure washers appear on the market. These devices wash not only cars, but also windows, walls and doors of houses, all kinds of household items that are difficult to clean with a brush and rag. Strong water pressure will cope with this task much more efficiently. The presence of such a device at home will save money that will be spent on washing the car in the service, while the water consumption will be minimal.

Internal washing device

The main parts are the engine and the pump, they create the right water pressure. It is recommended to use a single-phase electric motor with a potential of 220 V, it is easily accessible and safe.

To make the case, they choose a strong material, metal or durable plastic. But even when using a wear-resistant housing, it is not recommended to use the sink for more than three hours in a row. This will lead to quick breakdown.

A large variety of hose nozzles are available to facilitate cleaning - different hardness brushes, standard spray guns and soft rollers... If you buy a pair of these nozzles, you can significantly increase the functions of the sink, use it as a steam cleaner (you need a heater) or an automatic mop.

Internal pressure

The more pressure is created inside the housing, the stronger the stream of water from the hose will be, which means that the dirt will lag behind faster. The pressure must be set carefully, high pressure water can dent the vehicle or damage fragile parts. Manufacturers recommend setting the pressure in the range of 150-170 bar, 100 bar is enough to clean the machine.

If you cannot clean it with a jet of water, purchase a hose attachment, a turbo cutter. With its help, you can wash discs, tires and remove accumulated dirt in the cracks. To use a turbo milling cutter you need 160 bar.

Electric pump pump

Before buying a pump for designing a sink, you need to choose the right device like that. What material the pump will be made of will determine its durability.

The plastic pump will soon fail. Such a pump it is not recommended to use more than 20 minutes at a time... Reliable, but expensive, they are made of brass, as this material does not corrode.

How to use the mini sink

In order for the sink to work for a long time without breakdowns, you should adhere to the following rules:

1. Before using it, be sure to check the functionality of the sink.
2. Be sure to change the filter after each use.
3. If the electricity source is unstable, install a battery in the sink.
4. Replace damaged parts promptly if necessary.
5. Protect against voltage surges.

Subject to all the rules, your sink will last a long time.

Homemade sink

If you set out to make a do-it-yourself sink, you will need the following materials:

The choice of the volume of the canister depends on the purpose for which the homemade pressure washer will be used. A five-liter canister is quite enough for a car.

Choose a hose that is flexible and durable, it should not break. The most suitable option would be a nylon braided hose consisting of several layers. You cannot save on this component.

The pump can be used both by foot and electric... It is more convenient to use an electric pump, you will not need to do unnecessary physical footwork. However, the cost of such a pump will be several times more expensive.

Coupling and union select at your discretion, the main thing is that they have a tight connection with each other.

Make a hole in the canister to fit the size of the sleeve. Next, insert the connecting sleeve into the hole and screw the union. In order to maintain the required pressure in the canister, all structural parts are connected with a sealant.

The lid on the canister must be firm and sturdy... For higher tightness, put a rubber gasket on the bottom of the lid. Then drill a hole in it and insert the tubeless mushroom.

The canister is tightly twisted with a lid, and a cord from the pump is connected to the pre-cut mushroom. The hose is attached to the hole in the canister with a nipple. The device is ready!

The principle of operation of such a device is simple: with the help of a pump, air is supplied into the canister (it is not necessary to fill the canister with water to the brim). The created pressure will displace the water when you press the gun handle.

If the homemade device will be used in cold weather, it should be equipped with a heating element. For such a sink, a canister with a large volume is required, it will lose its mobility, but with the help of hot water, the dirt will be cleaned much faster and more efficiently.

In the modern world, every family has a car, and not just one. Whether domestic or foreign - they all require constant care. Any spare part has gone bad - you need to change it, a flat tire - pump up, a window is broken - insert a new one. And, of course, you should definitely wash your car. Car wash is not only necessary to keep the car clean. If you do not wash it, you can earn a fine from employees of the state traffic safety inspection. If not washed, the paint will soon wear off under the mud stain and the body will begin to rust. If you do not wash the interior of the car, it can be fraught with various respiratory diseases and allergies.

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

Homemade karcher with your own hands - the best option for washing a car

The choice of the way to wash your favorite car is the business of the car owner himself. Someone can pick up a rag and a bucket, someone can go to a car wash. But the ideal option is to make a homemade karcher. It can be done by investing a certain amount of money, or it can be done from improvised funds without investing money on it.

Of course, a homemade karcher will differ from a branded one, but it will fulfill its main purpose.

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

Karcher?

There are many ways to do it.

The first way. The main mechanism of the future Karcher is taken - the compressor. It can be taken from any technique that is no longer used on the farm. The mechanism is connected to the fitting using a hose. A brush is taken, to which it is attached is necessary in order to regulate the power of the water supply. A brush with a faucet is also attached with a hose. When fastening, you will need to use rubber gaskets, FUM tape, and hermetic glue. The hose on the other side 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. A more automated method could be made that would connect to the mains or cigarette lighter in the car.

Second way. A canister is taken into which more than twenty liters of water can be poured. A compressor from the car is connected to the inlet brass nipple from the tire. The hose attaches to the gun (you can purchase it at any garden store). The length of the hoses is at least six meters. Diameter 16 mm. For fasteners, 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). He must supply a high pressure of water, otherwise the manufacture of a home sink will run a cold. A homemade karcher should consist of a sturdy body made of metal or thick plastic.

The brush for the hose is different: from hard to soft. Rollers and sprayers can be used.

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