In this article, we will discuss and review the illustration of some main parts of a pressure washer. Their details about working would also be provided.
Main Components Overview
The first illustration of the main part is a pump. Since the sink is a water supply device, there is no way without a pump. Moreover, for the water to exit through the nozzle under high pressure, we select the pump at 150 bar. Some take more, but it’s enough. Otherwise, the paint will come off along with the dirt. The blockhead must be made of brass or bronze. Such materials are the least susceptible to corrosion, and therefore the device will last for a long time. Feeding at a rate of 15 liters of water per minute is enough to wash the car with high quality.
The next in line will be a 220V electric motor. In addition to it, a capacitor unit is needed so that the sink starts without problems. The higher the RPM, the better the performance. Too fast pumps, giving out a huge speed, will wear out quickly. Consumption of 2-3 kW and a rotation speed of no more than 2000 rpm is considered optimal.
Use a tank that you can power from a constant source of water. It can be an ordinary crane or a well, for example. If the water is dirty, put a filter at the inlet. The main tank will serve to add washing detergent for the car.
A special valve must regulate the operating parameters and, if necessary, redirect the unused water to the tank. This reduces the load on the pump. Understood the basic elements. But there is also a hose, nozzles and other components that are part of a homemade sink.
External mounted Components
External components are mounted on a frame, which is better to do it yourself or choose a suitable finished design. Usually, the frame is made on the basis of a profile or curved pipe. You can install wheels from below so that the sink is not stationary, but mobile. Stops, handles, and clamps will help in moving the device.
If you figured out the water intake, you need an element through which the liquid will begin to flow to the machine. Choose reinforced rubberized hoses or plastic products. Just make sure the hose is durable and has tight connections to the water intake. If necessary, you should be able to quickly repair the hose and change it. Moreover, the material of the outlet and inlet hoses should be such that it would not corrode for years.
Areas where the elements are interconnected and in contact with water are best combined with fasteners. They are mostly made of corrosion-resistant materials. For example, bronze or brass.
Pistol and nozzle
You can take a ready-made sandblaster or another suitable gun that has a nozzle. Apparently, they resemble pistols at gas stations. The jet of water should only come out when you press the button. It is better to take a ready-made gun.
