Do-it-yourself high pressure washer. Homemade homemade car wash Is it possible to make a pressure washer yourself

Very high popularity Lately got devices high pressure (AVD), most often they are used in car washes. With the help of AVD, you can quickly and efficiently wash the car body, engine compartment, such hard-to-reach places like the bottom and fenders. But the use of such units is not limited to the car: they are successfully used in agriculture, metallurgy, public utilities, etc.

The basic principle of cleaning is a directed jet of high pressure water. Coming out of a special nozzle (nozzle), it is able to effectively clean the most severe contaminants and eliminate complex blockages in pipelines.

Therefore, the "heart" of the AED- (or pump) high pressure.

Having carefully studied this article, you can easily assemble a fairly professional high-pressure apparatus on your own without much effort by purchasing components for assembly on our website.

Consider how you can assemble a medium-sized high-pressure apparatus for washing cars, cleaning pipelines with a diameter of up to 150-200mm, pumping sludge from wells and settling tanks, washing facades, and hydrosandblasting.

Price pressure washers consists of two main components: a pump (pump) and a drive (, an internal combustion engine, a hydraulic drive). This is the most expensive part in creating an AED.

Choice pumps(pump) high pressure. We will only touch on models with a crank mechanism.

It is necessary to rely on three main parameters: working pressure, productivity (water consumption) and shaft rotation speed. In order to cope with the above tasks, we need with a capacity of 900 to 1250 liters per hour and an operating pressure of 180 to 250 bar. Low speeds on the pump shaft have priority over high ones, as this increases the life of the pump. An important role is played by the width of the connecting rods on the shaft, however, with competent operation(sufficient level and timely oil change, prevention of overheating) - this parameter can be neglected.

electric motor. It is necessary to determine the power of the electric motor (or other drive). Many manufacturers of high pressure pumps are willing to publish information about this in the characteristics of their products. For example, let's take a capacity of 900 liters per hour and a working pressure of 200 bar. An approximate calculation, without delving into exact formulas, will be as follows: the product of productivity (l / min) and pressure (in bar) is divided by 550. We get the power value. Connecting the electric motor to the network is necessary through a contactor or a special starter. All equipment must be grounded.

by the most in a simple way connection of the pump and the motor is "shaft to shaft". With this method of mating, the motor has only one rear bearing, and the pump is bolted to the front cover of the motor. You can use other types of connections, using a flexible (elastic) coupling and flange, gearbox, belt drive using pulleys.

On the resulting "monoblock", at will and possibilities, you can "hang" pressure, switches "", thermal valve, damper, pressure gauge, cleaning filter and much more.

Frame.

If the device is to be used permanently, then there is no need for a frame. But then you will need to find a reliable place to mount the electric motor.

If AVD is supposed to be moved from place to place, then it will be required frame from metal pipes or profile, for mobility it can be equipped with wheels and an emphasis, as well as handles for easy transportation.

The quantity and quality of the water supplied to the high pressure pump is important.

Storage capacity. The best way to solve this issue is a storage tank that has auto-fill from water supply network using a conventional float valve. It is necessary that the container is not completely sealed, but excludes the possibility of dirt or particles getting into it, so as not to damage the seals or the ceramic inserts of the pistons (plungers). To do this, a filter is installed at the inlet to the tank and the necessary valve is arranged from above. Washing solution adding directly to the container is not recommended. For this, it is best to use sprayers, foam injectors.

Most high-pressure pumps are capable of taking water on their own (self-priming), but you should not place the pump above 0.5 meters and use a regular one to supply garden hose. For these purposes, you need to purchase a rigid hose (pressure-suction). The inner diameter of the hose for a pump with a capacity of 900 liters per hour must be at least 15 mm with a length of 3-5 meters.

Ordinary "soft" hoses are only suitable for use directly from a pressurized water supply network. But do not forget that in such networks there are problems with the water supply necessary for the pump. This can adversely affect the operation of the pump and shorten the life of the internal seals ().

Regulator. When installing a pressure regulator the best way connection will use a bypass channel with its circuit in a storage tank. In this case, when the gun is closed, the water will circulate through the container, and not inside the pump.

High pressure hose or - the length is selected as needed, several short hoses and a special connector can be used. So that the hose does not wear out prematurely, because. usually uncoated concrete floors in washing rooms, it is worth using a special spiral protection made of polypropylene.

For sewer cleaning hoses and (nozzles) are used.

, nozzles, nozzles- everything can be purchased specific tasks that you set to complete current tasks.

Important Tips:

Watch the threaded connections - they should not leak and be securely fastened.

Do not try to unscrew the hose, if it is under pressure - turn off AVD and take the pressure off!

Clean the filter regularly, even if it is "visually clean".

Do not use gun on-off switch unnecessarily - frequent operation wears out the gun regulator and valve!

Basically, for proper use AVD just read the instruction manual! Your device will serve you for a long time and will require regular replacement of wear parts in the pump - cuffs, valves, pressure regulator and scheduled oil changes.

Today, car washing is no longer a long and laborious task. A pressure washer helps you get the job done much faster and more efficiently. In addition, these devices can be used to clean windows, doors and walls of houses, barbecues - in a word, items that are not easy to clean with a brush and (or) rag. Water, which is supplied under strong pressure, does an excellent job of these tasks and helps save time. But such a device is not cheap. A good car wash costs from $150. That is, the possibilities of budget models are very limited. The way out is a do-it-yourself high-pressure washer. It is very useful to have such a device in the country.

Structure:

The main part of the device is an electric motor that creates a pressure of water. For this purpose, a pump is suitable, not necessarily a new one.
The motor is inserted into the body of the device and connected to the power supply.
The body must be made of durable material. For example, metal or thick-walled plastic.

Important! Even in this case, there is a limit on the time of continuous use of the sink. Do not use it for more than 3 consecutive hours. The sink will fail in the shortest possible time.

If you buy several brush heads, you can turn your own hand-made device into a multifunctional device. In particular, by equipping the structure with a water heater, you can use it as a steam mop or steam cleaner. The turbo cutter helps to wash tires, clean even the most difficult areas from dirt.

Internal pressure

The higher the pressure inside the housing, the more powerful the water jet from the hose. And this means that pollution is washed better. But the pressure must be set carefully, because water under pressure can simply break the car glass or leave dents on the body:

Pressure on industrial devices is 150-170 bar.
For a do-it-yourself sink, 100 bar is quite enough.
When using a turbo cutter, it is required more pressure- about 160 bar.

Electric pump pump

From right choice the pump depends on how well your self-assembled high-pressure washer will work. The material of manufacture of the pump determines its wear resistance:

The most budgetary and unsuccessful option is a plastic construction. The time of continuous operation of the sink in this case does not exceed 20 minutes.
More expensive, but reliable pumps are brass. They are not afraid of corrosion.

Rules for the safe operation of mini-sinks:

Before starting operation, check the device for operability.
After each use of the device, clean the filter thoroughly.
If power outages occur frequently, equip the appliance with a battery.
Do not allow children to use the car wash.
If you notice that some part is out of order, do not hesitate to repair. Replace it with a valid one as soon as possible.
Avoid fluctuations in air temperature in the room in which the device is located.

Self-made mini-sink

In order to make a car wash with your own hands, prepare in advance:

Pump.
Canister with lid.
Hose for watering with a "pistol".
Union.
Coupling.
Rubber gasket.

These are parts for a future car wash. From Supplies you will need drills and sealant.

Important! Before you make a high pressure washer, the question arises: what volume canister to choose? Practice shows that for the usual passenger car a 5 liter canister is enough. For washing the car, this is quite enough, and in the trunk such a unit will fit easily.

A few tips for choosing accessories:

There are two requirements for an irrigation hose: strength and flexibility. The best option- These are products with a braid of nylon. Multi-layer hoses are more durable and reliable. You should not save on them.
The pump can be used by foot or automatic. The latter option is much more convenient, since you do not have to carry the pump from place to place and at the same time wield your foot. The limiting factor is the cost: automatic pump costs three times as much.
Special requirements for fitting and coupling No. The main thing is that they are firmly in contact with each other.

Important! It is desirable that they are made of the same material - plastic or metal.

To connect the device to the water supply, you will need a long (5-7 m) hose. This is enough to smooth out the pressure. If the water source is a container of at least 30 liters, it is recommended to use a hose with check valve to increase the operating pressure.

Hull preparation:

Drill a hole in the housing (canister) that fits the coupling in size.
Insert the socket with the fitting into the hole.

Important! Do not forget to secure the coupling with sealant. This is necessary so that high pressure is maintained inside the canister, and the coupling does not pop out during operation of the device.

Now it's time to do the lid. The lid will need a hard and durable material. Fasten a rubber gasket to its bottom. Make a hole in it and mount the fungus from the tubeless tire.

Final build:

Attach the cord from the pump to the “fungus”.
Attach the free end of the hose with the fitting to the hole previously made in the body.

The sink is ready! The principle of action is as follows. The pump pumps water and air into the canister (no need to fill to the brim!). You press the handle of the “pistol”, and a jet of water beats under pressure.

Important! If you are going to use the car wash in cold weather, it is advisable to equip it with a water heater.

It can be used as an energy source for the device.

High pressure washers are widely used among residents of the private sector and car owners. This phenomenon is caused by the fact that the devices are used for various purposes: for cleaning paths in the backyard, when cleaning terraces, and even for washing cars and houses. To become the owner of the unit in question, it is not necessary to send it to a specialized store and spend a large amount of money. You can make an apparatus from a compressor and some other components.

Advantages of homemade equipment

If there is no financial opportunity to purchase a device, or there is a desire to assemble equipment for a high-pressure washer with your own hands, the instructions below will be of interest to you. Before you make a pressure washer, you should know about the advantages of technology:

low financial waste;
the possibility of modernization;
functionality at the level of production equipment;
fast production;
operational simplicity;
high efficiency;
no spare parts needed and no extra costs.

With the help of the equipment, it is possible to effectively, quickly and efficiently wash off pollution of any degree of complexity. You will be able to clean various surfaces car body. A home-made high-pressure washer, made and operated with your own hands, eliminates damage to the treated surfaces. This quality favorably characterizes the cleaning technique in the eyes of the user.

We make our own equipment

First of all, you need to choose a suitable pump for washing. It is planned to operate the equipment for commercial purposes - make a choice in favor of industrial equipment. The basic principle remains the choice of a plunger pump equipped with ceramic pistons. The crank mechanism increases the service life. The main parts of a pressure washer are:

washing filter;
hoses;
additional nozzles;
water containers;
detergents;
sandblaster for washing;
durable wear-resistant housing;
High pressure pump;
engine (petrol or electric).

Schematic diagram of work homemade car wash high pressure is as follows: water is transported to the container from a special container or water pipe, after which it is pumped through a pump. The maximum load provides pressure up to 160 bar. Water is supplied through a hose to a gun with a nozzle. Consider the main steps in the manufacture of a pressure washer:

The tank is equipped with a pump, and the connections must be completely tight and durable. Fixation involves the use of couplings.
On the other side of the tank, you will need to fix the hose with which water will be supplied.
The hose is equipped with a tip that directs the water jet.

An autoloading valve, produced in two variations, will need to be connected to the pump. The first type is represented by a closed valve. The system depressurizes after the gun is closed and then the water is pumped from the outlet to the inlet. It is recommended not to operate the device longer than 3 minutes. The valve with a supply differs in convenience. The liquid is transported through the collector to the tank or to the sewer immediately after the pressure is released (depending on the connection option of the sink).

There are two ways to connect the motor to the pump. In the presence of a motor with a full shaft, docking with the pump directly is possible. The motor shaft is placed on the front bearing, which creates an additional load. This technique shows the most economical results. If you make a sink with such an engine with your own hands, then it will have a significant overhaul period of operation. This is caused by high starting loads. It happens that it is not possible to remove the pump shaft from the engine. In this regard, it is advisable to install the device soft start.

Another method of coupling the motor to the pump is envisaged, which uses a clutch. It is used as a cushion, which softens the impact during the start-up of the equipment. The coupling serves as a protection that prevents the violation of the bearing of the shafts. In order to reduce the load during start-up, a soft start is allowed. Thanks to this element, it is possible to gradually increase the power in the system.

The sink is mounted on a frame. The installation of the electrical component, the gun with the nozzle, and the high-pressure hose is carried out sequentially. It is important that the equipment in question be installed according to the recommendations of the part manufacturers.

Follow the established algorithm for assembling the device, take into account the load present during the tightening of the bolts. Also use anaerobic fixatives.

The sink must be connected to the water supply system with a hose. The connecting hose must be at least 7 meters long. The length of the hose allows you to smooth out pressure drops in the water supply. Consider a sink filter. It is recommended to use a hose with a non-return valve, which increases the working pressure.

Debris accumulating in the filter element of the tank must be removed in a timely manner.
It is advisable to inspect the connections in time, tighten if necessary.
Every electrical element homemade sink must be grounded, for which use a flexible three-wire wire in double insulation. Also use a grounding plug for this purpose.
Connect the power outlet to earth ground securely.
The strong pressure of the jet produced by the apparatus is not needed. Otherwise pressure pump overloaded, which subsequently with a high probability will adversely affect the paintwork of the equipment. These actions will lead to moisture ingress into electrical equipment, damage to equipment and additional waste.
Choose a water pressure that is suitable for removing basic dirt from the surface to be treated.

The product must be necessarily convenient during operation, and therefore you should not resort to using big parts. If you live in an area where power is often cut off, it is advisable to provide alternative source power supply: equip the technique with a rechargeable battery.

The device of its own production is able to wash off pollution of varying complexity from any surface, from any object. Even the most stubborn stains of dirt will be removed without any streaks or residual dirt. The big advantage of the installation is the impossibility of damaging the treated surface during the cleaning process. Listen to the advice of experienced professionals - save time and money by creating useful home appliances with your own hands.

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 suitable 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 a overpressure. 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. To replace the constant use of the pump, you can install a pump that allows you to manually increase 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 and detergents in selected proportions and delivers 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, through inside cover is threaded with a nipple.

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 a 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.

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 having 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
- Automobile 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 fill 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 it is being used drill bit. 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 lid, the joint of the coupling, as in the previous step, is watered silicone sealant, after which this cover also needs to be dried.

Fastening is no longer needed, only a nut is needed, it is attached back side couplings. 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 great pressure water. 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 water is supplied under pressure in the future, the author inserted a rubber gasket right size into the second hose nut.
