Homemade nozzle for washing a car. DIY mini high pressure washer. Additional washing functions

Washing high pressure is a highly effective unit used for professional cleaning of cars - paintwork, engine compartment, rims, other elements.

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

This tool is used by service professionals, but homemade car wash high pressure with your own hands will cope with the task just as well.

What parts are needed to assemble a car wash?

Setting up a mini-wash is a simple process. The work begins with the selection of parts for subsequent assembly of the structure. The working part must be assembled from high-quality, proven materials. The components, with the exception of the pump, do not have to be new. But the serviceability is first checked to avoid breakdowns.

A pump or motor that creates water pressure - main detail. When choosing, pay attention to performance and the ability to create pressure. For infrequent use, at home, a pressure of 100 bar is sufficient. When installing additional equipment, nozzles, up to 160 bar is required. Average figures vary between 100–200 units.
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 accessible.
Coupling – necessary to connect the pump and the power plant. It is preferable to have models that can perform the functions of a fuse and balance the misalignment of the shafts along the axis.
Housing, water container – ensures a uniform supply of water masses. Tanks made of durable plastic or metal are used.
The frame is the basis for securely fastening the elements. Often additional wheels are installed at the bottom for mobility and ease of use.
A gun with a nozzle and hoses are required to supply water. The hose chosen is high-quality, reinforced.
Nozzles - used to change the nature of the water flow. There are many models used to solve specific problems.

You should not skimp on the quality of parts - this will affect the performance of the device.

To homemade sink high pressure was assembled correctly with your own hands, other components will also be required.

Additional items:

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

Having completed the collection of spare parts, you can begin fastening the elements and installing them on the frame. It is important to maintain the ability to repair equipment by more often using threaded connections.

During the assembly process of 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 entire structure:

it is planned to manufacture a system with optimal sizes, for which suitable pipes are selected - round, curved;
in addition to the wheels, it is advisable to install clamps at the bottom;
handle - makes transportation easier.

Grounding – safety element:

a three-core wire is selected;
you will need a plug with a grounding terminal;
The socket is grounded.

After preparation, several main steps are performed:

Electrical equipment is installed on the frame, including a motor, pump, and other structural elements.
A gun with a nozzle is attached, supplying water after pressing a special button. Such devices are used by professionals, but they can also be easily purchased in a store.
A high-pressure hose is being installed.

After completing the assembly, connect to the water supply. A 7 m long 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 advisable to ensure optimal operation, preventing the need for subsequent restoration.

Important points installation usage:

before starting, all connections and fastenings are checked;
the filter element needs to be regularly cleaned from contaminants;
You should not often use the equipment at full power;
Installing a battery will protect the device from power surges.

If you assemble the device yourself, subsequent restoration and replacement of rubber rings and seals will not cause any difficulties.

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

A small amount of tools is selected:

roulette;
knife;
Bulgarian;
wrenches;
pliers.

When thinking about how to make a foam generator for a car wash with your own hands, you should choose and suitable materials, parts for assembly.

Highlights:

A pipe with a length of at least 50 cm is required. It is filled with polyethylene sponge for subsequent foam formation.
A filter is installed in the form of a mesh to prevent filler from getting into other units.
One edge of the pipe must be plugged and a tee must be installed to subsequently secure the foam concentrate tap.
Using a fitting, connect the pipe and hose intended for foam.
A valve is connected to the other end, providing a flow of compressed air masses.

The characteristics of the foam that will be obtained as a result of the operation of such an installation are determined by the length of the pipe used. The density of filling the surface with a washcloth requires attention. For filling car 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 can easily cope with loads in conditions home use, perfectly replacing the factory tool.

Many car enthusiasts today prefer high-pressure washers to a regular rag when washing their cars. The fact is that washing provides more gentle cleaning of the paintwork. There is no need to wash the car with a sponge or cloth. A directed jet of water not only removes dust from the body, but also removes fairly strong dirt. Considering that there is plenty of dirt on our roads at any time of the year, we can safely talk about saving money when operating such devices.

Unfortunately, good car washes they are not cheap. Not all car enthusiasts can afford to buy them. Therefore, creating your own high-pressure washer seems to be quite an interesting option.

How to choose a mini washer?

All mini-washes should be divided into 2 groups: professional and household.

Professional car washes

Professional devices are characterized by increased reliability and excellent performance. But they are not available to everyone, as they are very expensive. And there is no need to talk about their compactness. The average weight of such devices is close to 100 kg. Even though they are mounted on wheels, they are not at all easy to move. The main advantage of professional AEDs lies in their characteristics:

Professional car washes can work without interruption for a long time.

Despite the attractive functionality, such devices are a specific product, and ordinary car enthusiasts almost never buy them. To ordinary people household mini-washers are sufficient.

Household AEDs

Household mini-washers can be used not only for washing car bodies, but also for solving the following problems:

Clearing clogged drains.
Cleaning garden tools.
Cleaning local area from construction waste.
Cleaning garden paths.
Cleaning walls, house facades and fences.

All household high-pressure car washes are divided into subgroups according to the following criteria: water temperature, type of power supply, power.

Household mini-washers can receive heated water from outside or heat it themselves. Unheated devices are slightly less expensive than heated devices.

Depending on the type of power supply, household high-pressure car washes come in petrol and electric.

Devices with gasoline engines are considered close to professional car washes. That's why they cost accordingly. The cheapest gas-powered car wash will cost the buyer $600. The most expensive one sells for $5,000. It is not surprising that they are not popular in our country.

Domestic high pressure car washes with electric motor – the choice of a simple car enthusiast. Based on their power, such devices can be divided into 3 groups:

Choosing a mini-wash

When choosing a household AED, The following parameters should be taken into account:

Performance.
Pressure.
Pump material.

Plastic pumps do not last long and are installed in inexpensive, low-performance devices that can be used to wash a bicycle, motorcycle or garden cart. It is not enough to wash a car. More precisely, with the help of such a car wash you can wash your car, but it will take a lot of time due to its low productivity.

The car can be easily washed using AED with brass or silumin pump. These are middle class household appliances. Their performance and pressure are sufficient to wash any passenger car. Essentially this is best choice for household use.

Of course, if a car enthusiast has extra money, he can buy a household high-pressure car wash upper class, but for the average car enthusiast this is a luxury.

If you don’t have the money to buy an AED or simply don’t want to part with a large sum, then you can make a high-pressure car wash with your own hands.

First you need to prepare the necessary details. First of all, choose a pump. It must meet the following requirements:

To secure the pump in the housing of a homemade AED, you will need a coupling. It is best to choose a soft model, as it will compensate for the misalignment of the shafts along the axes.

Let's not forget about water containers. This could be a large canister or barrel. It is advisable that the container has water supply. Be sure to install a filter at the outlet of the container. It will protect the pump from sand and other contaminants.

High pressure hose with a gun equipped with a nozzle that creates a working jet.

We hide the pump in a separate container and connect it through fittings to the main container with water and a hose with a gun. At the outlet of the pump we install a regulator with a closed By - pass.

Water container and pump container can be installed on a frame made of lightweight hollow pipes. For ease of use, the frame itself can be placed on support wheels.

All that remains is to supply power to the pump, which will begin pumping water from the main container through a hose with a gun.

Assembling a mini-wash with your own hands, do not forget to ground the device. Before starting, make sure that all electrical components of the washer are properly isolated from water.

During operation homemade apparatus The AED should regularly check the security of all fasteners and tighten them if necessary. Try not to load the device to the maximum, as this will lead to rapid wear of the pump. In addition, excessive pressure can easily damage paint coating body

As you can see, making a homemade Karcher is not difficult. But although such a device will be mobile, it can still be used only where there is electrical network at 220 volts. What if you need to wash your car while on the road? To do this, you can make a mini Karcher powered by a cigarette lighter.

To create it we will need:

We make a hole in the lid of the canister and insert the fungus from the wheel into it. The entire structure is reliably sealed.

We also make a hole in the bottom of the canister and install a fitting to which we attach a hose with a gun at the end. We connect the hose from the compressor to the fungus in the lid.

The simplest sink is ready for use. All that remains is to pour water into the canister, close the lid and turn on the compressor. It will provide the necessary pressure of the water jet at the outlet of the gun.

Of course, this mini Karcher cannot boast of high pressure, but it is quite enough to knock down road dust or wash away detergent from the car body while parked.

A device such as a high pressure washer has received widespread in a modern economy. With its help, you can wash a car, terrace, house, etc. At the same time, it is quite possible to build a sink yourself, without having any special skills.

The high pressure washer is presented in the form of a cleaning apparatus with which you can clean different surfaces supplied with high pressure water.

Externally, a household mini-wash is a compact, small in size apparatus. The case is made of plastic or silumin (materials that are quite resistant to mechanical stress).

Area of use of the device: cleaning various surfaces (car body, furniture, asphalt, tiles and much more).

How a high pressure washer works.

Inside the device is inclined the washer rotates under the influence of an electric motor. The plunger located on the washer moves along a forward-return path. At the top and bottom points of the trajectory, their movements open respectively suction valve and high pressure valve. He is responsible for supplying water through the hose to the sprayer, forming a set.

Device Specifications

The power of the device is determined depending on the planned frequency of use of the sink: the more often we want to use the device, the more powerful the device we need. There is a direct relationship between the washing power and its productivity: increasing the power entails increase jet pressure.
Water pressure and flow indicators are one of the most important characteristics. The level of efficiency of the device depends on them by approximately 80%. Important: for fruitful work The required amount of water must be supplied to the sink, determined on the basis of its technical characteristics. For example, water consumption the device is equal to 360 l/hour, and the water supply is only able to supply 200 l/hour, this can lead to damage to the sink.
In no case should the water temperature indicator cannot be exceeded, because the built-in pump is designed for a certain temperature. Usually the indicator varies within 50 degrees (for semi-professional and household devices).

Homemade mini-wash project

The proposed mini-wash project includes next set main elements:

pump;
electric motor;
coupling for connecting the first two positions;
container for water and detergents;
frame;
gun with nozzle;
high pressure hoses;
nozzles

The operating principle of the manufactured sink is very simple. After connections to water supply water enters the container, where it is pumped using a pump.

Preparing material and tools

To make a mini-sink you will have to acquire the following components.

The pump is one of the main components of the sink. The device performance should be quite high(developed pressure range: 100−200 bar). When choosing a pump for a mini-wash, you should also pay attention to the material it is made of. It is desirable that the cylinder head be made of brass, pump pistons are made of ceramic or durable metal. The period of operation of such a pump will undoubtedly please you.

A high pressure washer cannot be imagined without an electric motor. Obviously, with increasing engine speed pump performance also increases, and therefore the device as a whole. However, don't go overboard. The best option electric motor power - from 2 to 3 kW, rotation speed - 1500−2000 rpm. To ensure reliable start motor, you can use an additional capacitor bank.

The coupling connects the pump to the motor. The so-called soft coupling - the most acceptable option. It plays the role of a fuse in case the pump or motor jams, and can also compensate for minor axial misalignment of the shafts.

The optimal volume of the water tank is from 4 to 20 liters. It is recommended to install a special filter (fine mesh) at the outlet of the tank, which can trap particles of dirt and debris, preventing them from entering the pump.

The basis for fastening the sink elements is the frame. Traditional material its manufacture - curved pipes. Wheels and a stop are often attached to the frame so that the mini-wash can rest on them during operation. The handle on the frame will provide moving the device across the territory.

A pistol with a nozzle performs a rather serious function - shapes water jet. When you press the handle, liquid is supplied, this allows you to save water. It is better to buy the tip ready-made so as not to “rack your brains” over the design of the shut-off valve.

The device is usually equipped with a nozzle (or several), which creates a jet that is most convenient for washing various surfaces. As a tool in the process of construction device, you will need a knife, scissors, and sealant.

Do-it-yourself mini-sink assembly technology

One of the most important nuances when assembling the sink it is creating grounding. For these purposes, use a flexible three-core wire (double insulated) and a plug with a grounding terminal. At the same time, through the circuit The socket is also grounded.

The next step is to mount the sink on the frame, i.e. we sequentially do the following:

We install electrical equipment.
We mount the gun with the nozzle.
We install high pressure hoses.

When equipping a water tank with a pump, make sure that all connections are durable and airtight. It is also very important that the device is installed in accordance with the recommendations of the parts manufacturers.

Connecting a high pressure washer to the main water supply using a hose (acceptable hose length is at least seven meters).

Features of operation and repair

In order to prevent breakdown and further repair of your mini-wash, you should listen to the following simple recommendations:

do not allow children to play with the device;
When using the washer, hold the gun firmly in your hands;
do not direct the water jet at animals or people;
Do not use the device at temperatures below 0 °C.

If, however, your device needs repair, you can also do it yourself, provided that you know the design of the device.

So, what could go wrong??

The most common case is seal wear in the pumping mechanism, which leads to a significant decrease in its performance. In this case, the seals must be replaced.
Rubber rings can also wear out. in the regulator design pressure (if installed). A “symptom” of such a problem may be a decrease in the pressure and density of the jet.

Setting up a high-pressure washer with your own hands will not take you much time, and besides, will save your money. Other advantages of such a homemade device include:

absence of complex device components;
ease of use;
operating efficiency comparable to purchased devices;
very low probability of damage to the treated surface.

The benefits of a mini-wash in everyday life are undeniable. Given that proper use The device saves your time and money, providing you and your family with cleanliness and comfort.

The attachment to the compressor allows you to wash parts under high pressure. Let's take a closer look at it. This washing gun consists of a main element - an air blow gun. Its cost was around 200 rubles. All plumbing fittings cost around 200 rubles. For clarity, the gun is divided into two parts: the plumbing part and the gun itself. We put aside the plumbing part of the car wash to take a closer look at the second unit.

Gun car wash

Let's look at the gun itself. There is a Euro air entrance here. WITH reverse side there was a nozzle screwed in that blew out air. After it was unscrewed, it became clear that there was a ten thread there. The pitch of one turn is one.

Plumbing part

The plumbing part is a little more complicated. Two Christmas trees were used. The first one has an internal diameter of 1/2 inch. The second one has the same outer diameter parameters. A nozzle with an internal diameter of about 6 millimeters.

The mechanism of operation of the washing gun

Water enters through a quick release and a plastic tap. It rests against the tee and comes out through the nozzle. It is advisable to use a longer nozzle. In this case, its length is 20 millimeters. It is advisable to make it 50 millimeters long. You should not make it too narrow, as the throughput will be reduced.
The air that passes through the gun increases the force with which the water hits. Adjustment occurs using a lever on the handle.

Pros and cons

The positive thing about this device is its low price. The total cost with all parts was 400 rubles. That is, within this amount you can assemble your own reliable gun for washing parts. Second positive point- ease of manufacture. It is very easy to make it with your own hands.

There is another plus. If you have a compressor that is idle, you can make such a washing gun and wash various parts.
cons. The first and most important disadvantage is that in addition to water, air is also supplied to the nozzle, which reduces its performance.
In standard devices, only high-pressure water is supplied through the nozzles. But here the air reduces the impact force and the result is not the effect that we would like to have. The second disadvantage is the performance of the compressor. It will be easier for professionals to buy a Karcher than to fool around with a compressor. Although the compressor is more multifunctional. It can be used as a blower with this attack to wash parts. Its other function is a spray gun. Beginners often use a regular household compressor, which has low performance. Due to this, the power of the gun is reduced, since a household compressor has low productivity, about 200 - 300 liters per minute. This power is not enough to fully work without interruptions. Therefore, this is also a significant drawback of a device that you can make yourself.

A DIY pressure washer can be created using inexpensive parts. Such units have become widespread. Using the device, you can wash the terrace of your house or cottage, wash your car, and do many other operations that require the presence of high-pressure water. Anyone who has the simplest skills in using a tool can do a wash. By appearance homemade unit looks like a portable suitcase small sizes or floor polisher. Its body is made of silumin or plastic.

How does this type of washing work?

An electric motor is installed inside the unit, the shaft of which is connected to a plunger swash plate. When moving, the plunger describes a reciprocating trajectory. At 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. Which technical specifications at a similar sink?

To determine required power For such a device, you need to know how often you plan to use it. With a high frequency of work with such a washer, its power must 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 depends 75-85% on fluid flow. It must be supplied to the unit required quantity, otherwise the washer may fail.

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

The device does not contain highly complex components.
It's easy to use.
The efficiency of such a unit is on par with samples purchased on the construction market.
Low probability of damage to any treated surface.
Possibility of carrying out if necessary self-repair devices.

What does a homemade mini-wash consist of?

You can make a sink from such parts as:

High pressure pump.
Electric motor.
A special coupling that connects the first two positions.
Tank for water and detergents.
Main frame.
A gun equipped with a nozzle.
High pressure hoses.
Various attachments.

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

What parts are needed to assemble such a device?

First you need to buy a pump. This is the main detail of homemade units of this type. It should have fairly high performance at a pressure of 0.1-0.2 kilobar. Special attention it is necessary to pay attention to the material from which it is made. You need 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 operation of the created sink depends on this.

The other main part of the unit is the electric motor. As its speed increases, the performance of the washing pump also increases. For similar devices Electric motors with a power of 2-3 kW at a shaft speed of 1.5-2 thousand revolutions per minute are best suited. To ensure reliable engine starting, it can be equipped with starting capacitors.

The coupling must be soft: if the pump or electric motor jams, it will act as a fuse.

The water tank can be selected from 5 to 22 liters. It is advisable to install a filter at the outlet of this vessel. Usually this role is performed by a fine mesh. It traps unwanted particles in the water and prevents them from entering the pump.

The frame is the base on which all the elements of the sink are attached. Most often it is made from curved pipes. You can attach a stop and wheels to it, 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 hoses with reinforcement inside are best suited. Their thickness is selected to the average diameter. All their connections in the unit must be sealed and made of material that is not afraid of corrosion.

A pistol with a nozzle must be selected so that its trigger operates 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 operate for a long time without breakdowns, the following recommendations must be followed:

Before work, you should always check all connections and fastenings for reliability.
If there is a filter device at the outlet of the water tank, then it must be cleaned of particles and dirt every day after work.
There is no need to frequently use the washer in maximum power mode, as this sharply increases the load on the pump and can cause its failure.
To protect the washer from power surges, you can equip it with a battery.
When the device is in working position, the gun must always be in the operator’s hand.
It is better not to allow children near the sink: this can lead to an accident.
Water jets should not be directed at people or animals.
This device must not be used in temperatures below zero degrees Celsius.

If repairs are needed, you can do it yourself. But this is only if the design of the sink is known. Most often, the seal wears out 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.

Some designs of such devices have a pressure regulator. When its seals (rubber rings) wear out, the water pressure decreases and the density of the liquid stream decreases.

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

Technological process of device assembly

Tools required for work: tape measure, electric drill, hacksaw, wrenches, bolts, nuts, washers.

The main point when creating a 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 this, you can connect the device to the main ground loop.

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

Install an electric motor with a starting device. This is done using bolts inserted into the corresponding holes on the frame.
Install the electrical cable.
Place the pump and mount the coupling on the motor shaft.
The gun with the nozzle is attached to one of the high-pressure hoses, which extends from the pump outlet.
Attach a water tank to the frame. It is necessary to ensure that all connections are tight.
Complete 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 tap and draw water into the tank. After this, the electric motor is turned on. The pump should pump water through the hoses to the gun. They press its trigger and see whether the density of the emerging stream of liquid is satisfactory or not. If everything is in order, then using the attachments you can get different types jets for cleaning various surfaces. If the water does not come out in the volume that was expected, then you need to check all the fasteners and seals and then repeat the check again.

You can use the car wash to clean dirt from your car and other similar operations, provided you follow the operating rules.

Homemade car wash proper operation it can last for a long time.
