The working principle of the cleaning machine is to complete a suction and discharge process through the power driven pump to the water, and to transport a certain amount of water to the high pressure pipeline, so that it can reach the high pressure nozzle with great energy. The aperture of the high-pressure nozzle is much smaller than the diameter of the high-pressure pipe, so when the water reaches the high-pressure nozzle to flow out of the nozzle hole, it must be accelerated. Only in this way, through the nozzle hole accelerated condensation of water can form a jet. When the jet from the high pressure washer hits the cleaning object, it is called jet operation. When the impact force of high-pressure water jet is greater than the dirt and surface adhesion of the object, the high-pressure water jet will peel off the dirt and wash away, so as to achieve the purpose of cleaning the object.
The working principle of the high pressure washer is that the motor drives the three-cylinder piston pump to form a high pressure water flow, which plays a washing role on the surface of the cleaned objects through the plate machine spray gun. It is characterized by independent design, novel and compact structure, light weight, flexible and convenient operation, easy maintenance, stable and reliable performance, strong cleaning power, water saving and energy saving.
High pressure washer is generally divided into 2 kinds, there are hot water and cold water, but generally we commonly use hot water high pressure washer pressure is not higher than 250bar, hot water high pressure washer is mainly used to clean up difficult to wash dirt, hot water high pressure washer is used to heat, when the water through the expansion tube, the pressure of the expansion tube will be relatively large, If the capacity of the expansion pipe does not increase, the pressure of the hot water pressure washer will not increase.
If the pressure on the expansion pipe increases, so will the cost. Therefore, the working pressure of the hot water high pressure washer will be about 200bar. When the pressure is large, the high pressure cold water washer will generally be used to achieve the cleaning effect by its working pressure. When it is necessary to clean oil and various stubborn stains, the hot water high pressure washer or saturated steam washer will be used.
