Homemade minisink. How to make a high pressure washer with your own hands. Homemade mini-sink project

In the current world a large number of people have cars for personal use. But given so many cars on the roads, not every one of their owners has a garage to use where they can store useful things for their iron horse. It is far from a secret that a car requires personal care, it is especially pleasant to drive a clean car. To wash the car, it is not necessary to constantly stand in line for washing, or to buy a washing machine. In order to save money and time, you can make a mini-sink with your own hands, it will fit in the trunk, and you can use it anywhere.

Materials and tools:
- Plastic canister with two necks
- hose from washing machine 2 m long
- Watering gun on the hose
- quick-detachable fitting
- Tubeless tire valve
- Rubber gasket
- Coupling
- Screwdriver and drills
- Rubber adhesive or sealant
- Car compressor

Step one. Mounting the air inlet.
Having collected all the materials and preparing the tools, you can get to work. First of all, the author removes the lid from one neck (responsible for draining). Picking up a drill with a thick drill, he makes a hole in the center of the lid.

Note: when the sink is ready, when using the canister, you will need to lay it on its side, with the filling hole down (so that the water comes out under pressure). Therefore, the cover of this outlet is left for the junction with the hose.

The valve for the wheels is pressed into the hole of the drilled cover. Now you need to let the sealant dry.

Step two. Water outlet installation.
In this step, it's time to prepare the second lid. It is removed, and the drill is taken up again, only now the pen drill is already used. A hole is made in the cover in size corresponding to the diameter of the coupling.

A coupling is inserted into the hole prepared in the cover.

For better fixing on the cover, the coupling joint, as in the previous step, is poured with silicone sealant, after which this cover also needs to be dried.

Fastening is no longer needed, only a nut is needed, the reverse side of the coupling is attached to it. The connection is also secured with a sealant.

After drying all the connections, you can put the cover back in place.

Step three. Watering gun to hose connections.
The idea to use a hose from a washing machine came to the author for a reason, such a hose has the ability to withstand high water pressure. The cut off part of the hose is threaded into the union nut.

The hose section is fixed in a quick-detachable fitting using a special fastener.

The main fitting and its nut are twisted.

Now you can connect the fitting to the watering gun on the boom.

Step four. Connecting the hose to the canister.
In order to prevent air from escaping when pressurized water is supplied in the future, the author inserted rubber gasket right size into the second hose nut.

The nut is screwed onto the quick-release fitting.

On this, the assembly of a homemade mini-sink is ready!

Step five. Washing test in operation.
Water is poured into the canister.

In fact, buying a car wash 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. There may be difficulties with how to choose a device and which model to give preference to.

Relevant are the developments of Bosch, Stihl, Karcher, Huter and other brands. But there are car owners who do not want to spend money on ready-made solutions. They need to make everything by hand.

For me, a homemade car wash is something controversial. On the one hand, it shows your ability to create efficient and useful gadgets. On the other hand, it is much easier to buy a factory car wash, and not try to mold something from a high-pressure fuel pump (a fuel pump, if anything), look for a suitable gun, pump and other spare parts for a 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 spare parts that come across, it’s better not to start.

If you are ready to act consistently and competently, then maybe something sensible will work out. Homemade sinks are not a myth at all. A lot of people, including my friends, collected them. They work well. Although my foaming agent works no worse. 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. The first task will be to find a pump. Since the sink is a water supply device, there is no way without a pump. Moreover, in order for the water to exit 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 it's overkill. Otherwise, the paint will come 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. Feeding at a rate of 15 liters of water per minute is enough to wash the car with high quality.
2. Electrical engine. The next in line will be a 220V electric motor. In addition to it, a capacitor unit is needed so that the sink starts without problems. The higher the RPM, the better the performance. Too fast pumps, giving out a huge speed, 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. Coupling. It is needed to connect the pump to the engine. Some others install a belt drive in one step. With the help of this gearbox, the speed and load of the engine with the pump are balanced. The gear ratio must be selected based on the required output parameters.
4. Water tank. Use a tank that you can power from a constant source of water. 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 serve to add washing shampoo for auto.
5. performance regulator. A special valve must regulate the operating parameters and, if necessary, redirect the unused water pressure to the tank. This reduces the load on the pump.

Understood the basic 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 sold in stores sinks.

External car wash units

External components are mounted on a frame, which is better to do it yourself or choose the right one. finished structure. Usually the frame is made on the basis of a profile or curved pipe. You can install wheels from below so that the sink is not stationary, but mobile. Stops, handles and clamps will help 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 the hose is durable and has tight connections to the water intake. If necessary, you should be able to quickly repair the hose, change it.
• Connections. Areas where the elements are interconnected and in contact with water are best combined with fasteners made of corrosion-resistant materials. For example, bronze or brass.
• Pistol and nozzle. You can take a ready-made sandblaster 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. It is better to take a ready-made gun and not bathe. My advice to you.

We do everything consistently and accurately, connecting the elements tightly to each other. In fact, picking up the details and creating a full-fledged sink from them is not an impossible task.

But you still need a hole cutter, a whole bunch of different components. It is far from a 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 enjoys the result. Others twist and turn something, but as a result they go to the store and buy a foaming agent, combining it with a purchased branded sink. Although the 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 improvised 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. I think it's better to spend more money and less time at a trusted Karcher factory car wash, for example, than less money and more time for 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 leaders of the segment. Can you achieve similar characteristics with such devices by doing your own washing? Unlikely. Can you save? 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 you.

Today, you no longer need strength and time to fight dried-on dirt and dust that has clogged into nooks and crannies, because every year new models appear on the market. high pressure washers. These devices are used to wash windows, cars, walls and doors of houses, barbecues and other items that are difficult to clean with a rag or brush. A strong water pressure copes with this task much more efficiently and saves money spent on washing a car in a service, while water consumption is also minimal. Therefore, it is useful for everyone to have such a sink in their arsenal.

The leading companies in the production of high pressure washers are the German companies Bosch, Karcher (hence the second name of the sink - Karcher) and Elitech. The average price of these sinks on the market starts from 10,000 rubles. Inexpensive car washes cannot be used for more than one car per day, and the most expensive models are limited to seven cars.

Washing device

The main component of the sink (or Karcher) is the engine that creates the necessary water pressure. A pump or a motor is suitable (it is not necessary to buy a new one, take a working one from an old car), the motor is built into the sink body and must be connected to a power source. For the sink body (body), choose a durable material, thick plastic or metal. Even if you get a durable case, it's best not to use the sink for more than three hours in a row. This will disable the sink in a short time.
Hose attachments are available to facilitate the cleaning process - brushes of various hardness, soft rollers, standard sprayers. With the purchase of a pair of attachments, you can expand the functions of your sink, using it as an automatic mop or steam cleaner (it is required to equip the sink with a heater).

Internal pressure

The higher the pressure inside the housing, the stronger the jet of water from the hose, which means that the dirt lags behind more easily. Set the pressure carefully, because water can simply break a fragile car part or glass, leave dents. Manufacturers set the pressure at 150-170 bar, but 100 bar is enough to clean the car.
If the contamination cannot be cleaned with a jet of water, purchase a special nozzle for a hose, a turbo cutter. It will help wash tires, wheels, remove dirt accumulated in the cracks. You can use the mini-sink both outside and inside the cabin. If you are using a turbo cutter, you will need 160 bar pressure.

Electric pump

Before purchasing and using a pump in a sink design, read how to choose the right device.
The material of the pump determines the wear resistance. The unfortunate option is a plastic pump, which will soon fail if used for more than 20 minutes at a time. Expensive, but reliable pumps are made of brass, because it does not corrode. These pumps are rarely found in commercial car washes.

How to use the mini sink

To wash worked properly follow these guidelines.

• Be sure to check the performance of the sink before using it, this will save your time and health.
• The filter installed in the car wash should be cleaned and replaced after each use.
• If the washer uses electricity in operation, and the source is unstable, supply it with a battery.
• Do not let children use the sink.
• If repairs are needed, don't hesitate to do so. Replace failed sink components.
• Update your device pads.
• Protect your sink from temperature fluctuations.

How to make a karcher yourself

Although car washes have achieved wide application, their price is great. So, if you want to do your own washing, you need:

• canister;
• irrigation hose with a gun;
• pump;
• Union;
• cover for the canister;
• tubeless wheel fungus;
• rubber gasket;
• coupling.

These are the components of the future car wash. Materials that come in handy during the manufacturing process:

• drill;
• sealant.

First stage. The choice of components.

The required volume of the canister depends on you and the purpose for which you use the sink: for passenger car enough five-liter canister. Drivers carry a car wash in their luggage, and therefore choose a case both in terms of volume and dimensions.
The irrigation hose must be strong and flexible, it must not be twisted or broken. Nylon-braided hoses are considered durable. A hose consisting of several layers is more reliable. Don't skimp on this part. There is only one requirement for a pistol: it must be firmly attached to the hose.

The pump can be foot or automatic. The high power of this pump will not be useful to us, so do not buy an expensive one. Using an automatic pump is much more convenient than using a foot pump, since you do not have to constantly drag the pump from place to place and do unnecessary work with your foot. but decisive role plays the cost of the pump, automatic is three times more expensive.
Choose the fitting and the coupling at your discretion, the main thing is that they are in close contact with each other. It is preferable to purchase both the fitting and the coupling from the same material (plastic or metal).

Second phase. Canister preparation.

Drill a hole in the canister that fits your coupling. Insert a coupling with a screwed fitting into this hole. Secure the structure with a sealant so that the coupling does not pop out during operation, and the desired pressure is maintained in the canister.

Third stage. Cover collection.

The lid needs to be strong, solid and suitable for the canister. To prevent air from escaping from the canister, attach a rubber gasket to the bottom of the lid. Then make a hole in it and insert the fungus of a tubeless tire into it.

Fourth stage. Construction collection. Additional functions.

Tighten the canister tightly with a lid, connect the cord from the pump to the fungus, attach the free end of the hose to the hole made in the canister using a fitting. Homemade sink is ready. The principle of operation of such a sink is simple: using a pump, air is pumped into a canister of water (while the canister is not filled with water to the brim). Pressure up to 0.3 bar or higher if your canister can handle it. Under the influence of pressure, water shoots out of the gun when the handle is pressed.
If you will use the sink during the cold season, equip your sink with a special burner for heating water. For these purposes, you will need a more voluminous canister, it will lose mobility, but with the help of hot water the car is cleaned of heavily dried dirt.

Provide a power source for the sink. If the sink runs on fuel (gasoline or diesel fuel), then there will be no problems with moving. When planning an electric car wash, take care of a serviceable and affordable source of electricity. In this case, you are unlikely to be able to freely transport the sink from place to place, but you do not have to spend money on expensive fuel.
Decide in advance for what purpose you use the sink. If you want to clean the windows of a house or the wheels of a car, then a compact, mobile washer on wheels and with a long hose will suit you. When using a sink on an industrial scale, you will not need its ability to move, so it is better to design a stationary sink. It connects directly to the water supply. If necessary, set the automatic water supply to save.
If it is possible to save on water consumption, then it is impossible to save on the purchase of washing components. To prevent the item from becoming dirty after washing, purchase special filters. You do not need an expensive filter that purifies water to a drinking state. The filter is needed to purify water, at least from litter, which will disable the sink.

You can even earn money by designing a pressure washer if you open a car wash. The main thing is that the sink you made works. Using the car wash, you can clean bicycles, mopeds, cars, trucks and their components.

How to make a karcher powered by a cigarette lighter

This sink design is cost-free. The following is an instruction for creating a more complex model:
US you will need:

• windshield washer motor;
• irrigation hose with a gun;
• cigarette lighter (motor power supply), cigarette lighter plug;
• two hoses 3 meters long, one hose must fit freely into the other;
• corrugated hose with a diameter of 25-30 millimeters;
• switch;
• M8 bolt, washer and nut;
• two plastic canisters (volume 10 liters);
• 6 screws;
• two-core electric wire 5-7 meters long;
• plastic sleeve;
• power cable;
• car wash brush

Additional materials:

• sealant;
• drill.

First stage. Create a hose.

We make a small hole in the bottom of one of the canisters. Inside a thick hose (diameter 10 millimeters or more), a thinner hose (up to 6 millimeters) and a two-wire wire are placed. Then the hoses fastened by us are inserted into the opening of the canister. A plastic sleeve is threaded into the free end of the hose. Further, a thin hose is attached to the washer motor, the wires are also attached to the motor.

Second phase. Creating a canister with a double bottom.

The second canister is cut approximately in the middle in order to subsequently make a second bottom out of it with a shuttle. The motor is fixed on the second bottom of the canister, for these purposes it is used homemade clamp, which can be made from the remains of a cut canister. To do this, we need an M8 bolt and some sealant.
The wires are also fixed with self-tapping screws and sealant. Then they connect, again using self-tapping screws, the body of the structure: the second bottom and the hinged lid.

Third stage. Completion.

Using the power cord, the wires are connected to the cigarette lighter. A hole is made in the brush for the button, the switch is fixed. The brush itself is mounted on the edge of the hose with a plastic sleeve. Use the attached diagrams in your work to better understand the text.

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 plastic container with a tight screw cap with a capacity of 4 - 20 liters (canisters for storing gasoline are very suitable), watering gun, a set of quick-release hose connectors (3/4 threaded fitting, two connectors for the diameter of the hose, a 3/4 - 1/2 adapter) , an 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.

Sealant applied

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.

Connectors installed

A do-it-yourself pressure washer can be created from inexpensive parts. Such units are widely used. With the help of the device, you can wash the terrace of a house or cottage, wash a car and do many other operations that require the presence of high pressure water. Anyone who has the simplest tool skills can do a wash. By appearance homemade unit looks like a portable suitcase small size or polisher. Its body is made of silumin or plastic.

How does a car wash work?

An electric motor is installed inside the unit, the shaft of which is connected to a plunger inclined washer. The plunger during movement describe a reciprocating trajectory. On the upper and lower sections of this curve, the valves open alternately: suction and high pressure. Through these devices, water enters the hose, and then into the sprayer. What kind specifications at a similar sink?

To determine the required power of such a device, you need to know how often you plan to use it. With a high frequency of work with such a sink, its power should be increased - the performance of the device increases along with an increase in the pressure of the water jet. The efficiency of the entire device is 75-85% dependent on the flow rate of the liquid. The required amount must be supplied to the unit, otherwise the sink may fail.

The temperature of the water used must be within the operating range applied in the pump device. Usually this indicator has a spread within 55 degrees. Creating such a sink does not take much time, saves money and finances. The advantages of creating such a homemade unit are as follows:

1. There are no components of increased complexity in the device.
2. It's simple to use.
3. The efficiency of such a unit is on par with samples purchased on the construction market.
4. Low probability of damage to any treated surface.
5. Possibility of carrying out self-repair of the device if necessary.

What does a homemade mini-sink consist of?

You can make a sink from such details as:

1. High pressure pump.
2. Electrical engine.
3. A special coupling that connects the first two positions.
4. Tank for water and detergents.
5. Main frame.
6. A pistol equipped with a nozzle.
7. High pressure hoses.
8. Various nozzles.

Such a unit works according to the following principle: after the unit is connected to the water supply network, the water passes into the container, where it is pumped. Then it is fed to the hoses and through them is sent to a gun with a nozzle, through which any surface is cleaned, for example, the hood of a car.

What parts are needed to assemble such a device?

First you need to buy a pump. This is the main detail homemade units of a similar type. He must have enough high performance at a pressure of 0.1-0.2 kilobar. Special attention must be given to the material from which it is made. It is necessary to choose a model in which the head on the cylinder block is made of brass, and the pistons of the pump itself are made of high-strength steel or ceramics. The duration of the created sink depends on this.

The other main part of the unit is Electrical engine. With an increase in its speed, the performance of the washing pump also increases. For such devices, electric motors with a power of 2-3 kW are best suited at a shaft speed of 1.5-2 thousand revolutions per minute. To ensure the reliability of starting the engine, it can be equipped with starting capacitors.

The coupling must be soft: if the pump or electric motor is jammed, it will play the role of a fuse.

The water tank can be selected from 5 to 22 liters. At the outlet of this vessel, it is desirable to put a filter. Usually this role is played by a fine mesh. It traps unwanted particles that enter the water and prevents them from entering the pump.

The frame is the base on which all elements of the sink are attached. Most often it is made from curved pipes. On it you can fix the emphasis and wheels, which will make it possible to move the sink. The frame has handles for carrying it around the work site.

For hoses, plastic and rubber sleeves with reinforcement inside are best suited. Their thickness is selected with an average diameter. All their connections in the unit must be tight and made of a material that is not afraid of corrosion.

A pistol with a nozzle must be chosen so that its trigger works smoothly, without jerking. Tips are bought ready-made. The sink can be equipped with several nozzles that will create the desired jet shape.

How to properly operate a homemade sink?

In order for the unit to work for a long time without breakdowns, it is necessary to follow the recommendations of the following nature:

1. Before work, you should always check all connections and fasteners for reliability.
2. If there is a filter device at the outlet of the water tank, then it must be cleaned every day after work from particles and dirt.
3. It is not necessary to frequently use the washer in the maximum power mode, as this dramatically increases the load on the pump and can cause it to fail.
4. To protect the sink from power surges, you can equip it with a battery.
5. In the working position of the apparatus, the gun must always be in the operator's hand.
6. It is better not to allow children to wash: this can lead to an accident.
7. Water jets must not be directed at people or animals.
8. This machine must not be used at temperatures below zero degrees Celsius.

If you need repairs, you can do it yourself. But this is the case if the design of the sink is known. Most often, wear occurs on the seal in the pump itself. This can lead to a sharp drop in its performance. In this case, it is necessary to disassemble the pumping device and replace all gaskets.

In some designs of such devices there is a pressure regulator. When its seals (rubber rings) are worn out, the water pressure decreases and the density of the liquid jet decreases.

To fix this problem, you just need to change the seals in the pressure regulator.

Technological process of device assembly

Tools needed for work: tape measure, electric drill, hacksaw, spanners, bolts, nuts, washers.

The main point in creating the structure is the grounding device. To make it, you need to use a flexible cable with three cores. It must be double insulated. Then it must be connected to a plug with a grounding terminal. After that, you can connect the device to the main ground loop.

Then proceed to the installation of the sink on the frame. The sequence of operations is as follows:

1. Install an electric motor with a starting device. This is done using bolts inserted into the corresponding holes on the frame.
2. Install the electrical cable.
3. They put the pump and mount the coupling on the motor shaft.
4. The nozzle gun is attached to one of the high pressure hoses that extends from the pump outlet.
5. Attach the water tank to the frame. Make sure that all connections are tight.
6. Finish the installation by installing all high pressure hoses.

Now comes the stage of checking the operation of the device. To do this, the sink must be connected to the main water supply using a hose, which should be 7-8 meters long. Open the faucet and draw water into the tank. After that, turn on the electric motor. The pump should pump water through the hoses to the gun. They press its trigger and see if the density of the outgoing liquid jet satisfies or not. If everything is in order, then you can, using nozzles, get different types cleaning jets various surfaces. If the water does not come out in the volume that was supposed to be obtained, then you need to check all fasteners and seals and then repeat the check again.

It is possible to use a car wash for cleaning dirt from a car and other similar operations, provided that the operating rules are followed.

A homemade sink, if properly handled, can last a long time.
