How to make a car wash from an ohm 830 pump. Do-it-yourself high pressure washer. The choice of parts for washing

If there are drainage systems on public roads, then somewhere deep in the project. If they worked as expected, then there would be less problems with dirt or not at all. As, for example, in agrarian Holland. And the chernozem is greasy and the clay is sticky, and the cars are clean. Although it may not be a matter of drainage, the problem remains and it needs to be solved somehow. A huge amount of dirt and silicon dissolved in clay sticks to cars every day, and in order to get smeared, it is not at all necessary to make a tour of the collective farms of the Oryol region. It is enough to travel in a large city for several hours after the rain, and you won’t go to the garage without a car wash. The service is not as cheap as we would like, but you need to wash it. Therefore, counting how much it costs to use the services of a car wash, a crazy thought comes to buy a mini-wash high pressure, and even better, that is, cheaper, make a mini-sink with your own hands.

What should be a car wash

There is no need to talk about the advantages of a mini-wash over a bucket wash. The high-pressure jet will perfectly remove dirt from fender liner, bumpers, rims, and a good foaming nozzle will complete the job. The body will be clean and tidy until the next rain or trip out of town. It is possible to assemble a sink with your own hands, only you first need to know what indicators the design should have in order to have at least some sense from it. You need to come to terms with the fact that you won’t be able to build a Karcher 7-series, but you need to strive for this if you really want to save 7-8 thousand on a workable reliable unit. When planning the design of a home-made sink, you need to focus on the best branded models, so we will become equal to them.

Do-it-yourself minisink. Looking for easy ways

The main figure in the washing machine is the compressor, which makes a high-pressure washer out of a garden hose with a nozzle. The engine for the drive is the tenth thing. The main and most difficult task is to decide on the compressor and its type. You can go the easy way, as many do. Assemble the device according to the principle of a portable foam concentrate. For some reason, the famous Monsoon can serve as an example. The device is schematically a cylinder or any container, and in the case of Monsoon, a plastic cylinder into which air is pumped using any portable compressor. A blowing agent is not a high-pressure apparatus by definition, so wanting 180 bar output from it is pointless. Firstly, you still need to look for such a household compressor so that you can pump up a lot of pressure, and secondly, find such a cylinder so that it does not shatter to pieces.

Video on how to choose a pressure washer

Now about the price of the enterprise. Monsoon costs about 2.5 thousand rubles, and this is only a foam generator. It includes a cylinder, a hose, valves and adapters, seals, sprayers. The foam generator operates at a pressure of up to 5 atm maximum and cannot be called a high pressure washer. It can create a good foam (which then needs to be washed off somehow), with its help it is convenient to wash the engine compartment and disks of a simple configuration. You can increase the pressure, but to reasonable limits. The manufacturer of Monsoon carefully hints that it is not worth raising the pressure above 4 atm, and this is indicated by the restrictive valve. The configuration is normal, as for a foam generator, it works from the Aggressor pump, so you can’t jump above the ceiling. From this we can conclude.

You can assemble a pengenerator with your own hands, and this will not require mind-boggling costs:

• a plastic canister is needed, the more the better;
• flexible hoses, low pressure can be used;
• wheel inflation compressor, Berkut R20, Aggressor;
• fittings, gaskets, sealants clamps in place.

To give the device mobility, you can use a car compressor that runs on the cigarette lighter. For example, K50 at 12 volts can provide legal 2 atmospheres. You can inflate them with a nipple fitting from a tubeless tire. Thus, cheaply and cheerfully, you can assemble a foam generator with your own hands. But this unit is still far from a high-pressure washer.

Important features of the pressure washer

Device performance is not the best important indicator, but if a home-made mini-sink will draw water not from a water supply system, but from its own autonomous tank, then it is advisable to save water. On average, when washing a car using a bucket-rag method, 40-60 liters of water are consumed. Less will not work. From here you need to calculate the approximate volume of an autonomous cylinder. Branded sinks consume from 5 to 15 liters per minute. That is, if in a home-made sink the capacity of the cylinder is 25 liters, then water must be added every two minutes.

Pressure is a sore point. In sinks of the middle price range, Karcher or Stihl, high-pressure axial pumps are installed. Buying such a unit, in principle, is possible. Only it will cost from 40% of the cost of the entire mini-wash. Therefore, the profitability of the invention of the bicycle is rather unsteady. You can not accelerate to such pressure, but take the path of least resistance. Take the pump from the fuel system of any car, you just need to consider that it will not work for a long time. Gasoline is its only lubricant, and water is a lubricant of dubious quality, so it will die after the first major wash, and its repair is impossible. In this case, we will lower the pressure even more and install a 12-volt pump from the glass washer of any car.

Even with such a weak pump, we must not forget about the filters. Each model of a branded mini-wash for a car is equipped with an introductory filter. Firstly, because a rather large fraction can float in the water and it will damage the pump. And if it doesn’t hurt, it will clog the foam nozzle or spray nozzle. Secondly, it can get on the paintwork and leave a new scratch. The filter is necessary, but it is better to abandon replaceable cartridges in favor of a filter that can be washed.

Nozzles and additional nozzles offered by well-known brands are relevant only if serious pressure can be achieved. If the pressure of a home-made mini-wash is at the level of 1-2 atm, then only one spray nozzle will be enough to prepare the surface. There is no point in using foam nozzles, since such a device itself by and large is a foam generator.

Today, any car owner is puzzled by the question of its cleanliness. And it's not just about going to the car wash and washing the car, but also about how to keep it clean on your own daily. In this case, you can count on a pressure washer, which will help you easily keep your car clean.

Principle of operation

If we talk about the principle of operation, then any sink or mini-wash has two main elements around which the work is built - a pump and an electric motor. From the power and performance of these constituent parts will depend on the impact force of the water jet, which is used for hydrodynamic cleaning various surfaces. Note that excessive load on the engine can cause the washer 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 blows the motor stator, and the second is mounted on the shaft and ejects hot air from the housing. If the temperature rises above a critical level, the device turns off due to the temperature sensor. A pump with a cylinder block and a group of pistons is also responsible for the power 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 gun because of its shape. The pressure in this type of washer is about 100 atmospheres, although everything will depend on the specific device.

Device

Now it will be useful 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;
• pomp;
• fuse;
• filters.

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

The pump is directly responsible for increasing the pressure. An important criterion for this part is wear resistance. 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, because 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 controlling the operation of the entire pump. As soon as the water level reaches a critical point, the rotation of the engine becomes impossible. This is usually observed in the case when the liquid enters, but does not come out due to the fact that the hose is blocked, and the type of sink in question continues to work. The filter is the main protection element that protects the sink from the occurrence of mechanical problems due to sand or other foreign particles of considerable size entering through the nozzle.

Selection of necessary materials

Now let's start selecting necessary materials to make the type of sink in question with your own hands. First you need to select and purchase a number of parts. Purchasing a pump will take most amounts for the purchase of 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 pressure washer the best solutions there will be those that can develop pressure up to 110-190 bar. To create pistons, you should use durable solutions such as ceramic. For block heads - brass. And a large bearing area should fall on the special liners of the crank type system.

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 living conditions. Connecting to the mains will increase the efficiency of such equipment. You will also need to have capacitors and a single-stage type gearbox on hand. This is not to say that a home-made sink cannot do without these components, but if you want to extend its operational life, then these details will definitely not be superfluous.

You will also need an element such as a clutch. Its main purpose will be to connect the motor to the pump. It should be soft for the reason that it should compensate for various kinds of mismatches. In addition, it can be used instead of a fuse if there are any 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, is a water tank. A certain water volume will ensure the operation of pumping equipment in a uniform mode.

The container 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 strainer, which should ensure the purification of water that enters the tank. In addition, if some washing 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 pumping equipment. Often such a part is equipped with an automatic unloading valve that directs water along the return path when some unfavorable factors occur during the operation of the pump. In addition, for a pressure washer, we need a base. You can use a regular frame or a plastic bucket for this purpose. It will not be superfluous and a gun with a nozzle that 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;
• stationery 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, attach two hoses to it. The first will serve to receive water, and the second will supply it to the gun. We unscrew the special clamp, and then put it on the hose. After that, you should tighten everything and check the tightness of the connections. We take a blow gun, which is also attached to the structure with a hose and secured with a clamp.

It often happens that the blow gun comes with nozzles that are slightly unsuitable for connecting to the 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 gotta do electrical part. First you need to connect the activation / deactivation toggle switch to the wire. You can buy such a solution 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 wires 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 to the pump. At the same time, we connect the circuit using contacts.

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

A high-pressure washer is a highly efficient unit used for professional cleaning of cars - paintwork, engine compartment, rims, and other elements.

The device is necessary to create high pressure, strong water pressure, which ensures the cleaning of surfaces and structures.

Such a tool is used by masters in services, but a do-it-yourself home-made high-pressure car wash will cope with the task just as well.

What parts are required to assemble a car wash?

The device of a mini-sink is a simple process. Work begins with the selection of parts for the subsequent assembly of the structure. The working part must be assembled from high-quality, proven materials. Accessories, with the exception of the pump, do not have to be new. But first check the serviceability to avoid breakdowns.

1. The pump or motor that provides the creation of water pressure is the main part. When choosing, attention is paid to performance, the ability to create pressure. For infrequent use, at home, a pressure of 100 bar is sufficient. When installing additional equipment, nozzles required up to 160 bar. Average indicators vary between 100-200 units.
2. The electric motor is the power source of the system. At self assembly it is recommended to choose single-phase devices with a potential of 220V. They are safer and more affordable.
3. Coupling - necessary to connect the pump and the power plant. It is preferable to have models that can act as a fuse and balance the misalignment of the shafts along the axis.
4. Housing, water tank - provides a uniform supply of water masses. Tanks made of durable plastic or metal are used.
5. The frame is the basis for the secure fastening of the elements. Often, additional wheels are installed at the bottom for mobility and ease of use.
6. Gun with nozzle, hoses - required for water supply. The hose is chosen high-quality, reinforced.
7. Nozzles - used to change the nature of the water flow. There are many models that are used to solve specific problems.

It is not worth saving on the quality of parts - this will affect the performance of the device.

In order for a do-it-yourself home-made high-pressure washer to be assembled correctly, other components will be required.

Additional items:

• filter element - a fine mesh that prevents the ingress of particles of dirt, debris;
• capacitor, single-stage gearbox - optional components, but they make it easier to start, improve the quality of work, productivity;
• – can be used as a pump, base for a car wash, greatly simplifying the assembly;
• performance regulator, unloading valve - parts that ensure safety and efficiency of operation;
• clamps or hydraulic termination - will make the connections airtight;
• elements in contact with water are selected from corrosion-resistant alloys.

After completing the collection of spare parts, you can begin to fasten the elements and install them on the frame. It is important to maintain the possibility of repairing equipment, more often using threaded connections.

In the process of assembling a car wash, there are several important points that determine the safety of further operation and the absence of malfunctions.

The frame is the basis of the whole structure:

• it is planned to manufacture a system with optimal dimensions for which suitable pipes are selected - round, curved;
• in addition to the wheels in the lower part, it is desirable to install clamps;
• handle for easy transport.

Grounding - safety element:

• a three-core wire is selected;
• a plug with a grounding terminal is required;
• socket is grounded.

After preparation, several main stages are carried out:

1. Electrical equipment is installed on the frame, including an engine, a pump, and other structural elements.
2. A gun with a nozzle is attached, which supplies water after pressing a special button. Such devices are used by professionals, but they are easy to purchase in the store.
3. A high-pressure hose is being installed.

After completing the assembly, they connect to the water supply. A 7 m hose is suitable for this.

How to avoid unexpected device breakdowns

When thinking about how to make a car wash with your own hands, it is desirable to ensure optimal operation, preventing the need for subsequent restoration.

Important Points installation usage:

• before starting, all connections, fastenings are checked;
• the filter element needs regular cleaning from contaminants;
• do not often use the equipment at full power;
• installing a rechargeable battery will protect the device from power surges.

With self-assembly of the device, subsequent restoration, replacement of rubber rings, seals will not cause difficulties.

A car wash is used to remove debris, dirt from a car body and other parts. The foam generator allows you to maximize the quality of cleaning. It's also easy to make your own.

A small number of tools are selected:

• roulette;
• knife;
• Bulgarian;
• wrenches;
• pliers.

Thinking about how to make a foam generator for a car wash with your own hands, you should pick up and suitable materials, parts for assembly.

Basic moments:

1. A pipe is required, at least 50 cm long. It is filled with a polyethylene washcloth for the subsequent formation of foam.
2. A filter is installed in the form of a grid to prevent the filler from entering other nodes.
3. One end of the pipe must be plugged, a tee must be installed for the subsequent fixing of the foam concentrate tap.
4. Using a fitting, they connect the pipe and the hose intended for foam.
5. A valve is connected to the other end, providing a flow of compressed air masses.

The characteristics of the foam that will result from the operation of such an installation is determined by the length of the pipe used. Attention requires the density of filling the plane with a washcloth. For filling auto cosmetics, a container that can withstand the pressure exerted by the system is suitable.

A car wash and a foam generator are useful units that simplify the process of car care. They easily cope with loads in home use, perfectly replacing the factory tool.

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 a home-made unit is similar to a small portable suitcase or floor 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?

For determining required power 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. It must be supplied to the unit required amount otherwise the washer may be damaged.

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 if necessary self repair devices.

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 of home-made units of this type. It should have a sufficiently 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 the electric motor. 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 of jets for cleaning 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.

High pressure washer - convenient fixture, which allows you to easily wash the car, as well as other surfaces in everyday life. thanks to the strong pressure of water, such devices are able to clean even heavily soiled surfaces without the use of detergents.

Such devices are usually installed at car washes and cost a lot of money. The Karcher pressure washer deservedly gained popularity, but not everyone can buy it. Therefore, for use at home, you can make a car wash with your own hands. - a great alternative to professional ones, which you can assemble yourself from improvised means.

To make a Karcher pressure washer, you need to find the right materials. You can use improvised items or purchase new ones in the store. So, to create a minisink you will need:

The principle of operation of the device

Will work on the principle of conventional car washes. The water in it is supplied through a rubberized hose under high pressure. Air is pumped into the water tank by a car pump, which creates excess pressure in the tank. Water under pressure is supplied to the outside and is supplied when the trigger of the watering gun is pressed. Thanks to the strong pressure of water, with the help of a car wash, you can clean any surface.

In this case, the pump is used exclusively for pumping air into the tank. Replace the constant use of the pump, you can install a pump that allows you to manually raise the pressure. Also, plunger pumps are an alternative to automobile pumps.

Plunger pumps - modern devices, which belong to the hydraulic dosing type devices. The plunger pump independently mixes water in the selected proportions, detergents and feeds the mixture under high pressure. The disadvantage of installing such a pump is the excessive 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 in the lid of the canister, it is necessary to cut a hole that will be narrower than the nipple in diameter. After that, 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 water and detergents will also be filled.

Next, you need to prepare a system for connecting the canister to the watering gun. To do this, in the lower part of the canister, you need to cut a hole close in diameter to the coupling. The clutch is attached from the inside of the canister, you can start it with 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 to prepare the sink for work. To do this, plugging the fitting with your finger, you need to pour water into the canister. Also, any detergents can be added to the tank (specialized detergents for cars or household chemicals). The nipple must be connected to car pump and gradually pump up the canister with air. During 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.

After completing these steps, a rubber hose is connected to the fitting, at the end of which a watering gun must be attached.

Advice : You can check the correct assembly by pressing the trigger of the gun. If, as a result, a strong pressure of water began to flow from the gun, then the device was 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.
