How to make a high pressure washer with your own hands? How to make a high-pressure car wash with your own hands? Pump for homemade high pressure washer

A high-pressure washer is a convenient device that 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 are modern devices that belong to metering-type hydraulic devices. The plunger pump independently mixes water and detergents in selected proportions and supplies 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 this, a nipple is threaded through the inside of the lid.

Advice : If the hole is larger than required, the gaps must be additionally sealed.

Through the nipple in the lid, the pump will pump air into the tank, and 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 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 (specialized car washes or household chemicals) to the tank. The nipple must be connected to a 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.

Today, there is no longer any need to waste time and effort dealing with dried-on dirt and clogged dust. Every year new modifications of high 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 effectively. Having such a device at home will save money that would be spent on washing the car at a service center, while water consumption will be minimal.

Internal structure of the sink

The main parts are the engine and the pump; they create the required 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, choose a strong material, metal or durable plastic. But even when using a wear-resistant case, it is not recommended to use the sink for more than three hours at a time. This will lead to rapid failure.

There are a wide variety of hose attachments available, they serve to facilitate cleaning - different hardness brushes, standard sprayers and soft rollers. If you buy a couple of such attachments, you can significantly increase the functions of the sink, use it as a steam cleaner (a heater is required) or an automatic mop.

Internal pressure

The more pressure is created inside the housing, the stronger the stream of water gushing from the hose will be, which means that the dirt will fall away faster. Pressure must be set carefully, high pressure water can cause dents in 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 can’t clean it with a stream of water, purchase a hose attachment or a turbo cutter. With its help, you can wash wheels, tires and remove accumulated dirt in the cracks. To use a turbo cutter you will need 160 bar.

Electric pump

Before purchasing a pump to design a sink, you need to choose the right device. The material the pump is made of will determine its durability.

A 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, since this material does not corrode.

How to use the mini-wash

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

1. Before starting use, be sure to check the operation of the washer.
2. Be sure to change the filter after each use.
3. If the power source is unstable, install a battery on the sink.
4. If necessary, promptly replace damaged parts.
5. Install surge protection.

If you follow all the rules, your sink will last a long time.

Homemade sink

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

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

Choose a flexible and durable hose; it should not break. The most suitable option would be a hose with nylon braid and consisting of several layers. You cannot skimp on this component.

The pump can be used either foot or electric. It is more convenient to use an electric pump; you will not have to do unnecessary physical work with your legs. However, the cost of such a pump will be several times more expensive.

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

Make a hole in the canister that matches the size of the coupling. Next, insert the coupling into the hole and screw in the fitting. To ensure that the required pressure is maintained in the canister, all structural parts are connected with sealant.

The lid on the canister must be solid and durable.. For better sealing, place a rubber gasket on the bottom of the lid. Then drill a hole in it and insert the tubeless tire fungus.

The canister is tightly screwed on with the lid, and the cord from the pump is connected to the pre-embedded fungus. The hose is attached to the hole in the canister using a fitting. The device is ready!

The principle of operation of such a device is simple: using a pump, air is supplied to the canister (there is no need to fill the canister with water to the brim). The created pressure will displace 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 wash you will need a canister with a large volume; it will lose its mobility, but with the help of hot water the dirt will be cleaned much faster and more efficiently.

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. A good car wash costs from 150 USD. That is, and the capabilities of budget models are 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 a 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

The correct choice of pump determines how well your DIY high-pressure washer will work. The material used to make the pump determines its wear resistance:

• The most budget-friendly and unsuccessful option is a plastic design. 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. Supplies you will need are drills and sealant.

Important! Before you make a high-pressure washer, the question arises: what size canister should you choose? Practice shows that a 5 liter canister is sufficient for a regular passenger car. 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 is products with nylon braid. 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.

In the modern world, every family has a car, and not just one. Whether domestic or foreign, they all require constant care. A spare part has gone bad - you need to replace it, a tire has a flat - you need to pump it up, a window breaks - you need to put in a new one. And, of course, you definitely need to wash your car. Car washing is needed not only to keep the car clean. If you don't wash it, you can earn a fine from employees of the state road safety inspection. If you don’t wash it, the paint underneath the dirt stain will soon wear off and the body will begin to rust. If you do not wash the interior of your car, this can lead to various respiratory diseases and allergies.

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

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

Choosing a method for washing your favorite car is up to the car owner himself. Someone can pick up a rag and a bucket, someone can go to a car wash. But 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 means without investing in it.

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

Advantages of a homemade device: low price, compactness, ability to wash dirt out of any crevice, autonomy, does not require electrical power, you can always take it with you.

Karcher?

There are many ways to do it.

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

Second way. Take a canister into which you can pour more than twenty liters of water. A compressor from the car is connected to the inlet brass nipple from the tire. The hose is attached to a gun (you can purchase it at any garden store). The hose length is at least six meters. Diameter 16 mm. For fastening, rubber flaps, clamps and nuts are used.

The effectiveness of a homemade Karcher

The efficiency of a Karcher depends directly on the selected engine (compressor). It must supply high water pressure, otherwise the production of a home sink will run haywire. A homemade Karcher must consist of a durable body made of metal or thick plastic.

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

In any case, it is not advisable to use a homemade Karcher for more than three hours. Since this can lead to its early failure.

Washing your car with a rag and a bucket is, of course, good, but it is a somewhat outdated method. Have you ever seen a car being cleaned in car washes in this old-fashioned way? If yes, then don't go back there again. They clearly skimp 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 a high pressure car wash

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

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 should create a pressure of 100 to 200 bar. Such equipment will be quite productive and will be perfect for achieving our goals. When choosing a pump, you need to pay attention to what material it is made of. For example, the piston group is metal or a ceramic alloy, and the block heads are brass. Of course, you can take an alternative route and use a compressor instead of a high-pressure pump. It will be cheaper, but the system will be less productive.

Motor selection

We can't do without a good engine. It makes sense to choose a single-phase motor of low power. 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 sufficient. 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 your car wash will have a condenser and gearbox is up to you to decide. Such equipment can extend the service life of the system, but will significantly complicate the design. In addition, these elements are not at all mandatory; everything will work fine without them. In any case, doing a car wash yourself is not that difficult. Let's move on to the practical part.

DIY high pressure car wash

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

Another important element is the water container. 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 container. At the outlet of 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 to assemble a high-pressure car wash with your own hands.

Assembly of 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 it comes complete with an automatic unloading valve, which, if something happens, relieves pressure and takes the load off the pump. A regulator is necessary 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 operating mode.

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 attached to it. All this is connected to each other using high-pressure hoses. Pay attention to the quality of the connections, as they will be subject to serious stress during operation. After the structure is assembled, the mini-car wash is ready for use. Check it out. If everything is in order, then you can use it. 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 yourself 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 significantly simplified. In particular, we are talking about replacing failed components. Secondly, you can use any attachment. If you need to get a concentrated stream, one type will do, if you need a diffuse stream, another type will do.

Many people make mistakes at the stage of connecting the sink to the central water supply. The fact 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 operates from 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 often 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 not small. It can be made from a regular plastic sprayer, which is then connected to the sink.

Need to take into account

In general, we have figured out how to make a car wash. As you can see, there is nothing complicated. 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, don't forget to tighten them. Since the tank has a filter element in the form of a mesh, it will gradually become clogged. If you do not clean it, it will eventually reduce the flow of water to the pump. Remember to periodically inspect the filter and change or clean it if necessary. Well, when assembling the structure, use popular drawings of car washes, one of which you can find in this article. They will help you figure out what's what and carry out the installation correctly.

Conclusion

Do-it-yourself car wash is not difficult. You can sit and think much longer: “Shouldn’t I do the sink myself?” If you finally take it and start, the assembly work will be completed in a few hours. In any case, it makes sense to remember that your car's paintwork does not last forever and needs to be carefully maintained. By the way, many car enthusiasts do not recommend using car washes with a pump that creates a pressure of more than 200 bar. If such equipment is used at full capacity, there is a possibility of damaging the car’s paintwork. And the load on the engine and working parts of the units increases significantly. Even if there is a need to create high pressure, use it in short-term modes. In principle, this is all that can be said about how to build a car wash.
