In fact, buying a car wash for a car is not the most expensive task. Now the prices for various washing devices are quite low. For example, from 5 thousand rubles you will find a good device. Here, difficulties may arise with how to choose a device and which model to give preference to.

The developments of the firm Bosch, Stihl, Karcher, Huter and other brands are relevant. But there are some car owners who do not want to spend money on ready-made solutions. They need to make everything with their own hands.

For me, a homemade car wash is something controversial. On the one hand, it shows your ability to create effective and useful gadgets. On the other hand, it is much easier to buy a factory sink, rather than trying to mold something from a high-pressure fuel pump (fuel pump, if that), look for a suitable pistol, pump and other spare parts for the future washing complex.

But since you want to do it yourself, I'll tell you a little about whether it is possible to assemble a sink and how well such a household or stationary homemade product will work.

Main components

Since we do everything from improvised means, problems can arise with such a parameter as reliability. I believe that any sink or foam generator should be assembled in accordance with GOST and other requirements. If you violate all the recommendations, and sculpt the structure from the first available spare parts, it is better not to start.

If you are ready to act consistently and competently, then something sensible may work out. Homemade car washes are not a myth at all. A lot of people, including my friends, collected them. They work well. Although my foamer works just as well. Yes, I bought it and I'm not ashamed of it.

So, since we are talking about homemade sinks, let's see what components they are assembled from.

1. Pump or pump. Finding a pump will be the first priority. Since the sink is a water supply device, there is no way without a pump. Moreover, so that the water comes out through the nozzle under high pressure, capable of removing dirt from the surface of the machine, we select the pump at 150 bar. Some take more, but this is unnecessary. Otherwise, paint will fly off along with the dirt. The block head must be made of brass or bronze. Such materials are the least susceptible to corrosion, and therefore the device will last a long time. The flow rate of 15 liters of water per minute is enough to clean the car thoroughly.
2. Electrical engine. The next in line will be a 220V electric motor. In addition to it, a condensing unit is needed so that the sink starts without problems. The higher the RPM, the better the performance. Pumps that are too fast and produce high RPM will wear out quickly. Don't take them. A consumption of 2-3 kW and a rotation speed of no more than 2000 rpm is considered optimal.
3. Clutch. It is needed to connect the pump to the motor. Still others set the belt drive to one stage. With the help of this gearbox, the revolutions and loads of the engine with a pump are balanced. The gear ratio must be selected based on the required output parameters.
4. Capacity for water. Use a tank that you can supply from a constant water supply. It can be an ordinary crane or a well, for example. If the water is dirty, put a filter at the inlet. The main tank will be used to add the car wash shampoo.
5. Performance regulator. A special valve must regulate the operating parameters and, if necessary, redirect the unused water pressure into the container. This reduces the load on the pump.

We figured out the main elements. But there is also a hose, nozzles and other components that are part of a homemade sink. Or think about which one to choose among ready-made and store-sold sinks.

External units of a car wash

External components are mounted on a frame, which is best done by hand, or you can choose a suitable ready-made structure. Usually the frame is made on the basis of a shaped or curved pipe. You can install wheels from below so that the sink is not stationary, but mobile. Stops, handles and latches will assist in moving the device.

• Hose. If you figured out the water intake, you need an element through which the liquid will begin to flow to the machine. Choose reinforced rubberized hoses or plastic products. Just make sure that the hose is durable and has airtight connections to the water intake. If necessary, you should be able to quickly repair the hose, change it.
• Connections. Areas where the elements are connected to each other and in contact with water are best connected with fasteners made of corrosion-resistant materials. For example, bronze or brass.
• Gun and nozzle. You can take a ready-made sandblast or another suitable gun that has a nozzle. Outwardly, they resemble pistols at gas stations. The jet of water should only come out when you press the button. Better to take a ready-made pistol and not take a steam bath. My advice to you.

We do everything sequentially and carefully, connecting the elements tightly together. In fact, picking up parts and creating a full-fledged sink out of them is not an impossible task.

But you still need a hole cutter, a whole bunch of different components. It is far from the fact that they will be at hand or fit in size, type of material, and so on. Someone makes sinks from NSh 10 (gear pump) and rejoices at the result. Others twist and twist something, but as a result they go to the store and buy a foaming agent, connecting it with the purchased branded sink. Although a foam generator can be made from a compressor and auxiliary mechanisms, I would prefer the finished product.

In some cases, it is better to think about which sink from a leading manufacturer to take to wash your car, than to unsuccessfully try to assemble a sink from scrap materials for several days.

I am not at all opposed to doing useful things with my own hands. But in terms of washing, there are many pitfalls. As for me, it is better to spend more money and less time on a proven factory Karcher car wash, for example, than less money and more time on a homemade device. It is still unknown how this homemade product will work, and what surprises it will give out during operation.

The rating of factory washes clearly demonstrates the segment leaders. Will you be able to achieve similar characteristics with such devices, making a sink with your own hands? Unlikely. Can you save money? Probably yes.

You decide. I voiced my opinion. By the way, I suddenly realized that it was high time to wash the car. Therefore, I went to put my horse in order, which is what I wish for you.

Washing the car with a rag and a bucket is fine, but it is a somewhat outdated method. Have you seen at least once that a car was cleaned in such an old-fashioned way at car washes? If so, don't go back there anymore. They obviously economize on quality and neglect their employees. So, in this article we will talk about how to do a car wash with your own hands. The thing is very interesting and useful.

Features of high pressure car wash

We can say that such equipment is not a luxury. Today it is already a necessity. The fact is that this is the only way to thoroughly wash the engine compartment, the underbody and the body of the car. But most importantly, this requires little or no effort. All that is required of you is 20 minutes of attention.

The main components of a car wash

Although we will assemble the equipment ourselves, that is, in our workshop, we will need purchased parts, which, unfortunately, are often not possible to find in our garage. The first thing we need is a high performance pump. It must generate a pressure between 100 and 200 bar. Such equipment will be quite efficient and will be perfect for realizing our goals. At the stage of choosing a pump, you need to pay attention to what material it is made of. For example, the piston group is metal or ceramic alloy, and the block heads are brass. Of course, you can go the alternative way and use a compressor instead of a high-pressure pump. It will be cheaper, but the system will be less productive.

Motor selection

We cannot do without a good engine. It makes sense to dwell on a low-power single-phase motor. By the way, you can find it in your garage or remove it from an old washing machine or similar equipment. In general, a power of 200-300 watts is quite enough. A single-phase motor is an order of magnitude safer than a three-phase motor in terms of connection and somewhat more economical, so we will focus on it. But whether a condenser and a reducer will be provided in your car wash is up to you. Such equipment can extend the life of the system, but will significantly complicate the design. In addition, these elements are not required at all, everything will work fine without them. In any case, a do-it-yourself car wash is not so difficult. Let's get down to the practical part.

DIY high pressure car wash

Before proceeding directly to the assembly, you need to acquire additional elements. We need a coupling to connect the pump and the electric motor to each other. It is best to take a so-called soft coupling, which will compensate for the slight deviation of the shafts from alignment.

Another important element is a water tank. In this case, a plastic tank is the ideal solution. It is easier to carry than metal, and in terms of durability, it is not inferior to the latter. It needs to be connected to the water supply network so that there is always water in our tank. At the outlet from the tank, we install a fine mesh that acts as a filter. It will protect the pump from damage by foreign bodies. Well, now let's see how a high-pressure car wash is going to do it yourself.

Assembling the structure

In general, there is nothing complicated here. By the way, it is advisable to install a performance regulator. This element is optional. The fact is that an automatic unloading valve is supplied with it, which in which case relieves pressure and relieves the load from the pump. The regulator is needed in order to change the pressure in the system. Therefore, you can set it to maximum - and the jet will be very powerful - and to minimum - in a weak mode of operation.

A metal frame is used as a single base for all assembled parts and assemblies. An electric motor, a pump and a gun with a nozzle are fixed on it. All this is connected to each other using high pressure hoses. Pay attention to the quality of the connections, as they will be subjected to serious stress during operation. After the structure is assembled, the mini car wash is ready to go. Check it out. If everything is in order, then you can use. In case of insufficient pressure, we check the tightness of the connections and the operation of the pump.

Homemade car wash and its features

We have already figured out that it will be much cheaper to buy all the parts and assemble them on our own and get ready-made equipment. But I would like to note that a homemade car wash has a number of features. Firstly, its repair is greatly simplified. In particular, we are talking about replacing failed units. Secondly, you can use any attachment. If you need to get a concentrated jet, one type is suitable, if a diffused one, another.

Many make mistakes at the stage of connecting the sink to the central water supply. The point is that the length of the hose should not exceed 7 meters. This will eliminate possible pressure surges. If you neglect this requirement, then nothing good will happen. In the case when a mini-car wash is powered by a tank, you need to carefully select its volume. It is advisable to take a container of at least 30 liters and equip it with a check valve so that during operation it is possible to build up pressure. If you frequently wash a heavily soiled car at low temperatures, you will need a homemade car wash foam generator. The price of purchased equipment is about 5-9 thousand rubles. Agree, the amount is rather big. It can be made from a conventional plastic sprayer, which is then connected to the sink.

Need to take into account

In general, we figured out how to make a car wash. There is nothing complicated, as you can see. But there are a few simple rules that will help extend the life of such equipment. It is periodically necessary to check the reliability of connections, including threaded ones. If they are loose, do not forget to tighten. Since there is a filter element in the tank in the form of a mesh, it will gradually clog up. If it is not cleaned, it will eventually reduce the flow of water to the pump. Remember to periodically inspect the filter and replace or clean if necessary. Well, when assembling the structure, use the popular drawings of car washes, one of which you can find in this article. They will help you navigate what's what, and carry out the installation correctly.

Conclusion

Do-it-yourself car wash is not difficult. Much longer you can sit and think: "Shouldn't I make a sink myself?" If in the end we take it and start, then the assembly work will end in a few hours. In any case, it makes sense to remember that the paintwork of your car is not permanent and must be carefully monitored. By the way, many car enthusiasts do not recommend using car washes with a pump that generates a pressure of more than 200 bar. If such equipment is used at full capacity, then there is a possibility of damage to the paintwork of the car. And the load on the engine and working parts of the units increases significantly. Even if it becomes necessary to create a high head, use it in short-term modes. Basically, this is all there is to say about how to build a car wash.

Today, any car owner is puzzled by the question of its cleanliness. Moreover, we are talking not only about driving into a car wash and washing the car, but also about how to keep it clean on your own every day. In this case, you can count on a high pressure washer, which will help you easily keep your car clean.

Principle of operation

If we talk about the principle of work, then any sink or mini-sink has two main elements around which the work is built - a pump and an electric motor. The force of impact of the water jet will depend on the power and performance of these components., which is used for hydrodynamic cleaning of various surfaces. Note that excessive load on the engine can cause the sink to fail or overheat. To prevent this, a forced-type cooling mechanism is usually installed.

As a rule, we are talking about a pair of fans. The first one blows the motor stator, and the second one is mounted on the shaft and releases hot air from the housing. If the temperature rises above the critical mark, then the device is turned off due to the temperature sensor. A pump with a cylinder block and a group of pistons is also responsible for the force of the water jet.

That is, to put it simply, the liquid is transported with the help of tubes to the internal circuit, where, under the action of the pump, its speed and pressure increase. After that, the water leaves the device through a special valve, which is called a pistol because of its shape. The pressure in this type of sink is about 100 atmospheres, although everything will depend on the specific device.

Device

Now it will be superfluous to consider the washing device and understand what constituent elements it consists of. The design of any pressure washer will consist of 5 main and a lot of auxiliary elements. If we talk about the main ones, then we are talking about:

• motor;
• pump;
• pump;
• fuse;
• filters.

Now let's say a little more about them. The motor forms the basis of the entire structure. It is thanks to its presence that the pump operation can be achieved, which can be called stable. The electric option will be the most common, although stand-alone solutions exist. If we talk about autonomous options, then either diesel or gasoline will be fuel for them. If we talk about a pumping unit, then its main purpose will be to pump water from a special tank or from a centralized network. If we are talking about a centralized version, then the sink must be equipped with special hoses.

The pump is directly responsible for the increase in pressure. Wear resistance is an important criterion for this part. It should be said here that this parameter will depend on the material from which it is made. Most often these days it is made of plastic. This option is not very high quality, since if you use the device for more than 20 minutes, then its failure is almost guaranteed. There are brass solutions that will be more reliable. It should be said that the models on the market, as a rule, are equipped with plastic options. For this reason, a self-made model can be significantly more reliable.

The motor fuse is responsible for monitoring the operation of the entire pump. As soon as the water level reaches a critical level, the rotation of the engine becomes impossible. This is usually the case when the liquid enters in, but does not come out due to the fact that the hose is blocked, and the sink of the type in question continues to work. The filter is the main element of protection, which protects the sink from mechanical problems due to the ingress of sand or other foreign particles of considerable size through the nozzle.

Selection of the required materials

Now you should start selecting the necessary materials to make the type of sink in question with your own hands. You will first need to select and purchase a number of parts. The purchase of the pump will take most of the cost for the purchase of the components. But this element can be called, perhaps, the most important in this device. The emphasis should be on models that have high performance. Specifically for a pressure washer, the best solutions will be those that can develop a pressure of 110-190 bar. Durable solutions such as ceramic should be used to create pistons. For block heads - brass. And a large bearing area should fall on the special liners of the crank-connecting rod type.

The next point is the selection of an electric motor. It is better to take a single-phase option if the operation of the sink will be carried out in a domestic environment. Connecting to the mains will improve the efficiency of such equipment. You will also need to have on hand capacitors and a single-stage type gearbox. This is not to say that a homemade car wash cannot do without these components, but if you want to extend its service life, then these details will definitely not be superfluous.

An element such as a clutch will also be needed. Its main purpose will be to connect the motor to the pump. It must be soft because it must compensate for various kinds of discrepancies. In addition, it can be used instead of a fuse, if suddenly there are some problems with the gearbox or pumping equipment. Another necessary element, without which neither a sink, which is made of a compressor, nor a solution from a high-pressure fuel pump, can do is a water tank. A certain water volume will ensure the operation of the pumping equipment in a uniform mode.

The capacity can be represented by a tank or a canister, which in this case will not be so important. The main thing is that it is connected to the water supply network. In addition, it must be equipped with a mesh filter, which must ensure the purification of the water that enters the tank. In addition, if some detergent active substances are added to the tank, this will significantly increase the efficiency of the equipment.

Another rather important detail is the regulator, the main function of which is to regulate the performance of the pumping equipment. Often, such a part is equipped with an automatic unloading valve that directs the water along the return path when some unfavorable factors arise during the operation of the pump. In addition, we need a base for a pressure washer. You can use a regular frame or a plastic bucket for this purpose. It will not be superfluous and a gun with a nozzle, which will be fixed on the hose, as well as sleeves that are designed to work with high pressure.

You will also need to have some tools on hand:

• pliers;
• screwdriver;
• soldering iron;
• drill with a cone-type drill;
• office knife.

Procedure

Now let's proceed directly to the assembly of the type of sink in question. First, it will not be superfluous to check the performance of the pumping equipment. To do this, we attach two hoses to it. The first will serve to obtain water, and the second will supply it to the pistol. We unscrew the special clamp, then put it on the hose. After that, screw everything up and check the tightness of the connections. We take a blow gun, which is also connected with a hose to the structure and secured with a clamp.

It often happens that the blow gun has nozzles in the kit that are a little unsuitable for connecting to a structure. To solve this problem, you can unscrew the nozzle and screw in the carburetor jet, which will fit perfectly in the thread. Many people use a jet from a carburetor from a Zhiguli car. This solution is necessary to reduce the hole in the gun, which allows you to create a more powerful compact jet.

Now we should deal with the electrical part. First, connect the activation / deactivation toggle switch to the wire. This solution can be purchased at any store that sells electrical parts. If suddenly, for some reason, you want to make such a device mobile, then we take a screwdriver battery and solder the wiring to it along with the contacts so that the solder does not interfere with the charging connection in any way, and the battery can be recharged if desired. Now we fix the wires with electrical tape. Now we attach the wires themselves to the pump. At the same time, we connect the circuit using contacts.

If you want, you can also make an extension cord with wires of various lengths. Such a device will not be superfluous if there is a desire to use the car wash by connecting it to the car battery. Now the assembly of the device parts starts in a housing made of a plastic bucket. To do this, we punch 4 holes in its wall using the drill mentioned above. We attach the pump to the side of the bucket and tighten it with 4 screws and nuts.

How to make a pressure washer

Over time, pressure washers, mainly used for cleaning cars, have become more widespread in the domestic markets. Using such a 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. A very profitable idea is a high-pressure washer with your own hands, which allows you to significantly save money spent on periodic washing of the car. If we take into account the 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 off very quickly.

The easiest way to do your own wash 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. So, it should show high functional performance in one unit of time and work normally at a pressure of about 100-200 bar. Many electrically driven plunger pumps 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 if ceramics or durable metal will be used for the pump pistons. The best option for making a cylinder head is brass. Robust components guarantee a long service life.

The most profitable would be to purchase a pump with a working capacity of about 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 capacity.

Selection of parts for washing

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

But it should be borne in mind that working in this mode can negatively affect its resources. Do not give preference to models that are too fast. The maximum permissible rotational 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 reducer, which operates using a V-belt drive. Their gear ratio depends on the parameters of the pulleys (driven and driving). The characteristics of the distance between the axes of rotation play an equally important role in the activity of gearboxes.

To ensure the fixation of the pump and the motor, a clutch is usually used. The most suitable option is a soft coupling that can compensate for the minimum axial misalignment of the shafts and act as a safety element in the event of a gearbox or pump jamming.

A very important structural element of any sink is a water storage tank. In order to ensure the maximum pump performance, it is necessary to use a certain volume of liquid. For this, it is possible to use a special liquid tank capable of making up from the water supply network. It is imperative to install a filter element at the outlet from the tank (this can be an ordinary small network), 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 conventional detergent to the liquid.

A do-it-yourself car wash should have a pump performance regulator in its design. Usually, this device has a connection with an automatic unloader valve, capable of redirecting the liquid back to the tank in an emergency, 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 at the bottom of it and make an emphasis to give the structure stability during use. One end of the frame can be equipped with a special handle for transporting the sink around the yard or garage.

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

One of the most important elements that make up a hand-made sink are high-pressure hoses. A standard, not too thick, reinforced rubber or plastic hose can act as a sleeve. It should be borne in mind that all structural connections of the hoses must be made in compliance with the tightness conditions, on the one hand, and not be afraid of corrosion and 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 bayonets.

When constructing a sink with your own hands, you must also pick up a gun equipped with a nozzle. Thanks to its shape, an imitation of the shape of the working jet is obtained. Actually, in appearance it resembles a pistol used at gas stations. In order to start supplying water from the nozzle, press the handle. This is an undoubted advantage, since it saves a large amount of water: the liquid is supplied only when it is needed, by pressing the pistol grip. It is quite problematic to make a shut-off valve with your own hands; the most simple and reliable option would be to purchase a ready-made tip.

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

When performing high pressure, care must be taken to establish grounding. For this purpose, a three-core, double-insulated flexible wire and a plug supplemented with a grounding terminal are often used. It should be borne in mind that the power outlet also needs reliable grounding using a circuit.

Periodically, it is necessary to inspect all connections and fasteners and tighten them if necessary. The filter element of the tank should be cleaned of accumulated debris on a regular basis.

It is undesirable to use too often a jet of water with a strong pressure - this will overload the injection pump and damage the paintwork of the car. It is recommended to apply pressure that can contactlessly rid the machine of the main layer of dirt on the surface to be treated, and manually remove the remaining dirt with a brush.

How the pressure washer works

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

Any sink must have a device that regulates the nozzle. By adjusting the position of the nozzle, you can change the pressure or the 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 system, but also from a special reservoir - for example, a barrel of water. To improve the pressure in the sink, you can put the barrel on a slight elevation.

In the event of a power outage or the use of a sink away from outlets, 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 a large water saving, in contrast to manual sinks.

Back to the table of contents

Washing device

There must be an engine inside the pressure washer that causes the remaining parts to rotate and open - a valve, washer or sprayer. The result of its work is the unwinding of the washer and the movement of water along the sprayer according to the forward-return trajectory, as a result of which the water enters the sprayer valve. The result of the action of many mechanisms is the formation of a powerful pressure and water supply.

It is advisable to choose the body for the sink made of impact-resistant plastic. The same requirements apply to the hose connected to the atomizer, as it will have to interact with a strong water pressure.

No matter how durable the materials of which the sink is made, it is highly discouraged to use it for more than two hours in a row. Too long operating cycle can lead to rapid wear of the constituent parts and shorten the service life of the device several times.

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

Main parts of the pressure washer

A DIY sink consists of the following elements:

• durable, wear-resistant housing;
• an engine powered by gasoline or electricity;
• a pump operating at high pressure;
• containers for water and detergents;
• additional attachments;
• water filters;
• hoses.

The principle of operation of a homemade sink is extremely simple. From a water supply system or a special container, after connecting, water enters the sink container and is pumped out using a pump. At maximum load, the washer operates at a pressure of about 160 bar. For comparison, a stream of water from a conventional tap is supplied under a pressure of five bar.

The next step is to supply water through a hose to the nozzle gun. It is advisable to equip the gun with a special nozzle that allows 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 a large area (porch or car body), a fan jet would be the best option. In order to remove fragments of stubborn dirt, it is advisable to use the point version of the water supply.

Additional options include a rotating nozzle, rotating brush and much more. The main advantage of using nozzles is non-contact cleaning of the surface, which significantly reduces the risk of damage to the paintwork of the car body or the decorative surface of the facade tiles.

When choosing parts for your sink, do not chase after maximum power. A household sink can function normally at an operating pressure of 100 bar. Moreover, for a person who has not previously encountered such a technique, it will be problematic to control a high pressure washer.

The use of foam for non-contact car wash provides better surface cleaning. The advantage of this method of washing is also "delicacy" - the foam will not damage the body. Therefore, many motorists strive to make a foam concentrate for car washing with their own hands.

Principle of operation

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

1. The jet of water passes through a car shampoo suitable for a foam generator.
2. It mixes with the air stream and foam begins to form.
3. At high speed, the resulting substance is directed to a special foaming "tablet".
4. Foam of the required density is already coming out of it.

The foaming agent allows cleaning very quickly, besides, it significantly saves water. For a jet, a small amount of water is enough, high pressure will provide the desired spray rate and surface area to be treated. Thus, the foam concentrate and high pressure car wash very quickly occupy a leading position in the list of tools necessary for a garage, according to motorists.

How to collect the foaming agent

The foam unit itself consists of several parts:

1. Compressed air cylinder.
2. Application gun.
3. Mixer parts.

A professional industrial foam concentrate is very expensive, so it makes sense to assemble a foam generator for car washing with your own hands.

At a price it will be much more affordable, besides, the work efficiency will remain the same. There are several ways to create a foaming agent:

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

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

Do-it-yourself foam nozzle for car washing is done in the same way. Sometimes motorists need a separate foam nozzle, if it was not in the purchased set for a factory-made wash.

Such a self-made device is likely to work much more efficiently than many commercial foam guns.

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

Metal tubes must be screwed into the container from the sprayer. At one end, a fitting and a non-return valve must be installed, and at the other end, a container for connection with a foaming tablet. The air supply for this foaming agent must come from the bottom. After completing the assembly of a foam generator for a car wash with your own hands, you can use it.

You can use more than just a garden spray as a water container. The most reliable option would be a propane cylinder, as it can withstand high pressure.

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

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

It is impossible to use a foaming agent or a high pressure car wash for a very long time in a row. This could lead to damage.

DIY car wash creation

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

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

First you need to find the right parts. These include:

1. Pump.
2. Electric motor.
3. Clutch.
4. Water tank.
5. Pump performance regulator.

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

Single-phase 220V electric motor can be used for car wash. The connection will be secure and inexpensive. The higher the engine speed, the greater the level of performance. The electric motor will be connected to the pump by a coupling. It is best to use a soft clutch, which can act as a fuse if the pump fails.

The water tank must be voluminous so that the pump can work for a long time without interruption. Plumbing tanks are often used. At the junction with the hose, you can attach a mesh so that no debris will ruin the pump. The material of the container must be chosen carefully, as it must be durable. Thick metal or plastic will do.

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

Washing your car can be made more efficient by attaching a brush or other attachment to the water hose.

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

It is impossible to work for a long time with the help of one and the same sink, since it, thus, will quickly become unusable. The purpose for which the sink will be used affects its final dimensions. In appearance, the sink can be:

1. Compact.
2. Large stationary.

The second option is more difficult to use at home and requires a fair amount of garage space.

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

There are several basic rules for use:

1. Regular inspection of the connections and their tightening will help prevent mechanical damage caused by strong pressure.
2. Inspection of filters before use - regular cleaning will ensure an even flow of water.
3. Electrical grounding - not only the motor must be grounded, but the plug itself. Then the device will be safe.
4. Washing should be carried out over the entire surface so as not to damage the paint that covers the car. If there is a drawing or decal on the machine, do not direct a jet of water at this element, as it can lead to cracks in the coating or peel off the decal.
5. It is advisable to use a battery in case of a poor-quality source of electricity. This will save the unit from a short circuit.
6. Avoid temperature fluctuations - sudden changes in air temperature can damage the instrument.

When using it, it must be remembered that it is not allowed to wash the car everywhere. Washing a car near bodies of water and lakes can result in a fine. This rule, however, does not apply to keeping headlights and glass clean.

You can use a high pressure car wash not only outside the car, but also inside. This will allow you to clean the interior very quickly and efficiently. A wide selection of attachments and rollers will help you to do even delicate cleaning in the car.

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