Such a device as a high pressure washer, has become widespread in the modern economy. It can be used to wash a car, a terrace, a house, etc. At the same time, it is quite possible to build a sink by yourself, without having any special skills.

High pressure washer представлена в виде уборочного аппарата, с помощью которого можно осуществлять чистку разных поверхностей, подаваемой под высоким давлением водой.

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

Use area of ​​the device: cleaning different surfaces (car body, furniture, asphalt, tile and much more).

The principle of the high pressure washer.

Inclined inside the device the puck rotates under the action of an electric motor. Located on the plunger washer moving along a forward-return path. At the top and bottom of the trajectory of their movement are opened, respectively suction valve and high pressure valve. He is responsible for the flow of water through the hose to the sprayer, forming a set.

Technical characteristics of the device

1. The power of the device is determined depending on the planned frequency of use of washing: the more we want to use the device, the more powerful the device we need. There is a direct relationship between the power of the car wash and its performance: an increase in power entails increase jet pressure.
2. Pressure and flow rates are among the most important characteristics. Approximately 80% of the efficiency level of the device depends on them. Important: for fruitful work, the right amount of water should be supplied to the sink, determined on the basis of its technical characteristics. For example, water flow the device is equal to 360 l / h, and the water supply is able to supply only 200 l / h, this can lead to breakage of the sink.
3. The water temperature indicator is by no means cannot exceed, because the built-in pump is designed for a specific temperature. Typically, the indicator varies within 50 degrees (for semi-professional and household appliances).

Draft homemade mini-wash

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

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

The principle of operation of the manufactured washing is very simple. After water connections Water enters the container where it is pumped through with a pump.

Next, water is fed through a hose to the gun with a nozzle. If the gun is equipped special nozzle, you can change the nature of the flow of water, which is determined depending on the surface to be cleaned.

Cooking material and tools

For the manufacture of mini-car wash you have to get following components.

The pump is one of the main components of the sink. The performance of the device must be high enough (pressure range: 100−200 bar). Choosing a pump for a mini-wash, you should pay attention to the material of its manufacture. It is desirable that the cylinder head was made of brass, Pump pistons are made of ceramic or durable metal. The period of operation of such a pump, of course, will please you.

Мойку высокого давления нельзя представить без электродвигателя. Очевидно, с increaseм частоты оборотов двигателя increases and pump performance which means the device as a whole. However, you should not “overdo it”. The optimal variant of the power of the electric motor is from 2 to 3 kW, the rotational speed is 1500−2000 revolutions per minute. To provide safe start Motor can use an additional block of capacitors.

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

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

The basis for fixing the washing elements is the frame. The traditional material of its manufacture - curved pipes. Often the wheels and the support are attached to the frame so that the mini-sink can rely on them in the process. The handle on the frame will provide device movement by territory.

I recommend using high pressure hoses. reinforced hose medium thickness (plastic or rubber). Remember, hose connections must be tight, non-corrosive and easy to disassemble.

A rather serious function is performed by a nozzle gun - forms the shape water jet. By pressing the handle, the liquid is supplied, it saves water. The tip is better to buy in finished form, so as not to "puzzle over" the design of the gate valve.

Аппарат обычно доукомплектовывают насадкой (или несколькими), которая формирует струю, максимально удобную для мытья different surfaces. В качестве инструмента in the process of construction the device you need a knife, scissors, sealant.

Assembly technology mini-wash their own hands

One of the most important nuances when assembling a car wash is grounding creation. For these purposes, use flexible three-core wire (double insulated) and a plug with a grounding terminal. At the same time through the contour grounded and outlet.

The next step is to mount the car wash on the frame, that is, consistently perform the following:

1. We mount the electrician.
2. We mount the gun with a nozzle.
3. We carry out installation of a high pressure hose.

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 mounted in compliance with the recommendations of manufacturers of parts.

We connect high pressure washer to the main water supply with a hose (acceptable length of the sleeves - at least seven meters).

Features of operation and repair

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

• Do not forget check reliability fasteners and connections;
• if there is a filter element in the water tank, regularly clean it of dirt accumulated during operation;
• Try not to use maximum power too often. Permanent work in this mode significantly increases the load on the built-in pump;
• recommend additionally equip battery washing - insurance against voltage surges.

Note also several recommendations regarding safety measures in the process of using a mini-wash:

• Do not allow children to play with the device;
• in the process of using the sink firmly hold the gun in your hands;
• Do not direct water to animals or people;
• Do not use the device at temperatures below 0 ° C.

If, nevertheless, your device needs to be repaired, you can also carry it out yourself, provided that you know the design of the device.

So, what can break?

1. 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 should be replaced.
2. Rubber rings can also wear out. in the design of the regulator pressure (if installed). A "symptom" of such a problem may be a decrease in the pressure and density of the jet.

The high-pressure washing device doesn’t take much time with your own hands; besides, save your money. Among other advantages of such a homemade device:

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

The benefits of a mini-washing in the home are beyond doubt. Provided proper use the device saves your time and money, ensuring you and your family cleanliness and comfort.
