How to make a sink out of a compressor. How to make a pressure washer

In order for the car owner to be able to wash his car at a convenient time at home, he will need to use a high-pressure washer.

This equipment is produced under the Karcher brand, it has a high performance, as a result, the washing result is practically the same as if the car was sent for service. The high cost of such washing equipment will pay off over time. However, if you know how to make Karcher with your own hands for washing, then you will save a lot of money and stay in the black.

Requirements for a homemade Karcher

A properly assembled home-made Karcher practically does not differ from the branded one in terms of its technical characteristics. The main thing is to take into account the requirements, which are presented to the unit:

It will not be difficult for a craftsman to make a Karcher with his own hands. To create a mini pressure washer you will need:

Algorithm for making a mini-sink

When assembling a structure, it is very important to follow the sequence of connecting parts. In strict sequence are installed:

The principle of operation of this device made independently is as follows: the pump is turned on, then the water goes into the hose from the canister, then the trigger of the gun is pressed, the water is supplied by pressure in a thin stream. You can also use a nipple for cars designed for tubeless tires, as well as a pointed knife.

The algorithm of work is as follows:

Safety precautions when using the sink

When using homemade washing safety rules must be observed, which will also extend the period of its operation.

Be sure to take into account the limit of the cycle of operation of the device. So, if you purchase a ready-made device, then the instructions contain information about how long it can work. The cycle can be 20, 30 minutes long or hourly, it all depends on the performance of the device. And if you do not comply with the specified time period in the work plan, the device will overheat and break.

A homemade device is best used for no longer than twenty minutes. And you can also calculate the time of use yourself, it all depends on the amount of tank assembly material and its quality. The more plastic is present in the structure, the shorter the cycle will be.

It is not recommended to fill the tank with technical or river water, since they contain a large number of elements undesirable for the device, which negatively affect the quality of its operation. To the tank no small particles or chemical elements, as well as to protect it from mechanical damage, it is recommended to install an additional filter for water purification.

It is also extremely important to ground all electrical equipment with a three-wire insulated flexible wire and a plug with a grounding terminal. The entire structure and filter must be cleaned periodically.

That at home, to successfully wash a car, many people prefer to purchase expensive Karcher equipment. But you can save a lot, assemble its analogue with your own hands. How to do this was mentioned above.

» From the material presented by the author, you will learn how you can independently make a full-fledged mini-high-pressure washer that works from a 12 V screwdriver battery, you can also connect to a car battery through an extension cord with alligator clips.

All motorists are well aware of how the car constantly gets dirty, especially in spring and autumn, in summer after rain. As the saying goes, "I just left the car wash and then bang torrential rain," many have come across this. Every time you don’t run into a car wash, periodically it runs like that in a month, and without that money is needed for spare parts for gasoline, etc.

It is allowed to wash cars only at specially equipped stations if you are in the city, but you still need to look for a way to save your money, and for this reason the author came up with a portable, compact mini-wash. It consists of a high-pressure pump, 8 atmospheres at the outlet, a blow gun, a flexible hose, a 12V screwdriver battery, wires and a body made of an ordinary plastic bucket, you also need a container for taking water (bucket, canister, bottle)

The advantage of this sink: water intake from any container, low consumption, the ability to work autonomously without an electrical outlet, thanks to the battery.

And so, let's take a closer look at what exactly is needed to create a mini pressure washer?

materials

1. high pressure pump 8 atmospheres
2. 12V battery from a screwdriver
3. plastic paint bucket
4. wires
5. switch
6. contacts
7. solder
8. water tank
9. hose
10. jet from the Zhiguli carburetor
11. gum
12. bolts
13. nuts
14. washers
15. crocodiles

Instruments

1. drill with cone drill
2. stationery knife
3. screwdriver
4. soldering iron
5. pliers

Step-by-step instructions for assembling a mini pressure washer with your own hands.

First, we check the operation of the pump (the author ordered it from China), we connect the hoses, there will be 2 of them, that is, one for water intake, and the second for feeding into the gun. We unscrew the blue clamp and put it on the hose.

Now we twist and the whole connection is tight, the hose has nowhere to go.

Connect the hose and secure with a clamp.

Instead of a native nozzle, a jet from a Zhiguli carburetor is screwed in; it fits perfectly on the thread.

Everything is now much smaller in the gun opening, which will contribute to the creation of a strong compact jet.

Such a switch is also inexpensive and can be bought at any specialized store.

The master soldered wires with contacts to the battery of the screwdriver, doing this with the expectation that the solder did not interfere with the connection of the charger and the battery could be recharged.

The wires are fixed with electrical tape.

Also, the wires practically do not interfere and the battery can be freely connected to the screwdriver itself.

And together the circuit is connected through contacts (father + mother).

After that, the master proceeds to assemble all the details of the mini-sink in the body of a plastic bucket, for which he drills 4 holes in the wall of the bucket using a drill with a conical drill.

The pump is wall mounted.

Tightened with 4 bolts and nuts.

At the bottom of the bucket, a mount was also made for installing a screwdriver battery, for which an elastic band and a bolt with a nut were used.

A mount is also provided for the extension cord, and it is located under the bucket lid.

Then holes are again drilled in the bucket for the gasket and hose connections.

As you remember, there are 2 hoses, one for inlet and one for outlet.

Everything fits compactly in this plastic bucket, the only thing is that the container must be taken separately.

Today, you no longer need 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 utensils that are difficult to clean with a brush and a rag. Strong water pressure is much more effective to cope with this task. The presence of such a device at home will save money that will be spent on washing the car in the service, while water consumption will be minimal.

Internal washing device

The main parts are the engine and the pump, they create the necessary 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 a sink for more than three hours in a row. This will lead to a quick breakdown.

A wide variety of nozzles for hoses are available, they serve to facilitate cleaning - different stiffness brushes, standard sprayers 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 (requires a heater) or an automatic mop.

Internal pressure

The more pressure is created inside the body, the stronger the jet of water from the hose will be, which means that the dirt will fall behind faster. Pressure must be set carefully, high pressure water may 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 a jet of water fails to clean, purchase a nozzle for a hose, a turbo cutter. With its help, you can wash discs, tires and remove accumulated dirt in the cracks. To use a turbo cutter, you need 160 bar.

Electric pump

Before buying a pump for designing a sink, you need to choose the right device. The material from which the pump is made 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 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, the following rules should be followed:

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

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

Homemade car wash

If you set out to make a sink with your own hands, you will need the following materials:

Canister volume selection depends on the purpose for which a home-made pressure washer will be used. A five-liter canister is enough for a car.

Choose a hose that is flexible and durable, it should not break. The most suitable option would be a hose with a nylon braid and consisting of several layers. You can't skimp on this part.

The pump can be used both foot and electric. It is more convenient to use an electric pump, you will not have to do unnecessary physical work with your foot. 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.

In the canister, make a hole suitable for the size of the coupling. Next, insert the coupling into the hole and screw in the fitting. In order to maintain the desired pressure in the canister, all structural details are connected to the sealant.

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

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

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

If a home-made 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.

Despite the wide range of services, it is not always possible to wash your car at a car wash. Sometimes you do not need to urgently wash the car, you just need to wash the lights and windows or polluted places after parking the car under the trees. Sometimes only a wet rag is enough for this, but sometimes a bucket of water is not enough. Those who have worked with Karcher portable mini sinks know that the water consumption when washing a car is much lower. The secret of the master offers the design of a portable sink, let's call it low pressure. But this washing will allow, in the absence of running water, to bring the self-washing of the car closer to a civilized method and to drastically reduce water consumption.

How to make a homemade karcher for a car

The design of the sink is extremely simple, to create it you will need a plastic container with a tight screw cap with a capacity of 4 - 20 liters (canisters for storing gasoline are very suitable), a watering gun, a set of quick-release hose connectors (3/4 threaded fitting, two connectors for the diameter of the hose , adapter 3/4 - 1/2), automotive nipple for tubeless tires and a piece of hose 1.5 - 2.5 meters long. From the tool you need a knife with a sharp end, silicone sealant and a car pump or compressor.

The principle of operation of a mini sink. A hose with a watering gun is connected to the bottom of the water tank. A car nipple - a fungus - is built into the filler neck. We fill the container with water 3/4 - 4/5 of the volume, tighten the lid and pump the container with air. An overpressure is created in the system under the influence of which water will flow out when the trigger of the gun is pressed.

The assembly diagram of a mini sink with careful execution should not cause difficulties

1. With the sharp end of the knife, slowly and carefully form a hole in the lid of the container, slightly smaller than the diameter of the nipple.

2. Insert the nipple from the inside. Tests have shown that the nipple becomes tight and does not need additional sealing.

Hole for nipple Nipple inserted into cap

3. At the bottom, even without protrusions or a seam of the canister, we slowly and carefully make a hole for the coupling.

4. Using a wire from the inside of the canister, we wind the coupling into the hole.

5. We apply silicone sealant to the junction and screw the fitting to the coupling. We are waiting for the sealant to harden.

6. We twist the lid. We are waiting for the sealant to harden. We connect the pump. We plug the fitting with our finger and increase the pressure in the container, if everything is done carefully, the container will keep the pressure.

7. We equip the hose with connectors. We connect one end of the hose to the canister, and the other to the watering gun.

8. Fill the canister 3/4 - 4/5 with water and pump air inside. We do not pump the canister strongly, it expands under pressure (becomes more round). Don't get carried away with increasing pressure. When using large volume canisters, it will be necessary to provide clamps to prevent excessive inflation of the container.

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

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

Basic principles for 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 per unit of time and work in normal mode at a pressure of about 100-200 bar. Many electrically driven plunger pumps have these characteristics. When choosing a pump for your future sink, special attention should be paid to the material that has become the basis for its working part. The best option is if ceramic or durable metal is used for the pump pistons. The best option for the manufacture of the cylinder head is brass. Durable components are the key to 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 power.

The choice of parts for washing

Scheme of a homemade mini-wash.

When choosing an electric motor, you should pay attention to models that have a power supply of about 220 or 308 volts. In the event that the pressure washer will be used at home, it is advisable to use a single-phase 220 volt connection, as it will not entail additional costs and meets all safety requirements. To ensure optimal starting of certain motors, it is desirable to use additional capacitor banks. So, the performance of the pump 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 too high-speed models. The maximum allowable speed in this case is up to two thousand revolutions at a power of two or three kilowatts.

A high-pressure washer of a certain design makes it possible to provide the necessary pump performance when using a single-stage gearbox operating with a V-belt drive. Their gear ratio depends on the parameters of the pulleys (slave and driver). An equally important role in the activity of gearboxes is played by the characteristics of the distance between the axes of rotation.

A coupling is usually used to ensure the fixation of the pump and motor. 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 case the gearbox or pump is jammed.

A very important structural element of any sink is a water storage tank. In order to ensure the maximum performance of the pump, it is necessary to use a certain volume of liquid. To do this, it is possible to use a special liquid tank capable of replenishing from the water supply network. Be sure to install a filter element at the outlet from the tank (it can be an ordinary small network), designed to clean the liquid from dirt particles and prevent blockages from entering the pump. To enhance the washing effect, a special or conventional detergent can be added to the liquid.

Hydraulic scheme of a car wash.

Do-it-yourself car wash should have a pump performance regulator in its design. Usually this device is connected to an automatic unloader valve capable of redirecting the liquid back to the tank in an emergency so that no harmful load is placed 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 the convenience of its use, you can fix a pair of small support wheels in its lower part and make an emphasis to give stability to the structure during use. One of the ends of the frame can be equipped with a special handle designed to transport the sink around the yard or garage.

The main structural element of a homemade sink is a water tank. In order to ensure maximum pump performance, a certain volume of liquid must be used.

One of the most important elements that make up a do-it-yourself sink is 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 hoses must be made in compliance with the conditions of tightness, on the one hand, and not be afraid of corrosion and easy to disassemble, 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 building 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 the water supply from the nozzle, press the handle. This is a definite plus, as it allows you to save a large amount of water: the liquid is supplied only when it is needed, when you press the pistol grip. It is quite problematic to make a shut-off valve with your own hands; the simplest and most reliable option would be to purchase a ready-made tip.

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

When installing a high pressure washer, care must be taken to create grounding. For this purpose, a three-core flexible wire equipped with double insulation is often used, and a plug supplemented with a ground terminal. 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. Regularly clean the filter element of the tank from accumulating debris.

It is undesirable to use a jet of water with high pressure too often - this causes excessive load on the injection pump and damages the car's paintwork. It is recommended to apply pressure that can contactlessly remove the main layer of dirt on the surface to be treated, and manually remove the remaining dirt with a brush.

The principle of operation of a pressure washer

Thanks to the devices operating at high pressure in the range of 120-150 bar, dirt can be removed from almost any surface. It is worth being prepared for the fact that a small layer of plaque will still remain after such processing.

Handmade car wash.

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

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

In case of a power outage or 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 kind is the great water savings, in contrast to manual washing.

Washing device

Car wash device.

Inside the high pressure washer, there should be a motor that provokes the rotation and opening of the remaining parts - the valve, washer or sprayer. The result of its work is the untwisting of the washer and the movement of water along the sprayer according to the forward-return trajectory, as a result of which water enters the sprayer valve. The result of the action of many mechanisms is the formation of a powerful pressure and water supply.

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

No matter how durable the sink materials are, it is highly recommended not to use it for more than two consecutive hours. Too long a cycle of work can lead to rapid wear of the component parts and shorten the life of the device several times.

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

The main parts of a pressure washer

A do-it-yourself sink consists of the following elements:

Scheme of a homemade mini-wash.

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

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

Homemade car wash.

The next step is to supply water through a hose to a gun with a nozzle. 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 spray. The nature of the water supply should be determined based on how the surface will be cleaned. For example, to cover a large area (veranda area or car body), a fan jet would be the best option. In order to remove fragments of stubborn dirt, it is advisable to use a point version of the water supply.

The role of additions can be a nozzle with a rotary nozzle, a 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 tile.

When choosing parts for washing, you should not chase after achieving maximum power. A sink used at home can function normally at an operating pressure of 100 bar. Moreover, for a person who has not previously encountered such a technique, it will be problematic to manage a high-pressure washer.

Additional washing functions

Wash power diagram.

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

Water heating can be ensured by installing a special burner inside the housing. The installation of additional elements affects the dimensions of the entire structure - if there is a desire to provide the sink with an additional function, it is necessary to choose a slightly larger body for this.

Sinks that are not designed for heating water are more compact and maneuverable in use.

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

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

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

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

Many take on the creation of a do-it-yourself car wash for profit - a car wash that operates at high pressure is able to serve a considerable stream of cars. Many modern car washes work with such devices. Remarkably, such a car wash can be used both for cleaning cars and for motorcycles, bicycles and components.

Step-by-step instructions for creating a sink

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

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

Washing mini-post AROS.

There are two ways to connect the motor and pump to each other. If a full shaft motor is available, it can be directly coupled to the pump. In this case, the motor shaft will be located on the front bearing and create an additional load on it. This will be the easiest and most economical option. It should be borne in mind that a do-it-yourself sink with a similar engine will have a short overhaul period due to high starting loads. A situation may arise when it is not possible to remove the pump shaft from the engine. To avoid the development of such situations, it is advisable to install a soft starter in the sink.

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

The next step is to mount the sink on the frame. The following actions are sequentially performed with their own hands - installation of electricians, a gun with a nozzle and a high-pressure hose. It is very important that the pressure washer is installed in accordance with the recommendations of the parts manufacturers. It is necessary that the assembly sequence is strictly observed, the load exerted on the bolts being screwed is taken into account, anaerobic clamps and the like are used.

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