How does a pressure washer work?

High pressure washer is a machine that flushes the surface of objects by making the high pressure plunger pump produce high pressure water through the power device. It can peel off dirt, wash away, to achieve the purpose of cleaning the surface of the object. Because it is the use of high pressure water column to clean up dirt, unless it is very stubborn oil stains need to add a little cleaner, otherwise the foam generated by strong water pressure is enough to take away the general dirt, so high pressure cleaning is also recognized as one of the most scientific, economic, environmental protection cleaning ways.

High pressure cleaning machines are generally divided into 2 kinds, there are hot water and cold water, but generally we commonly used hot water high pressure cleaning machine pressure is not higher than 250bar, hot water high pressure cleaning machine is mainly used to clean up the dirt difficult to wash, hot water high pressure cleaning machine is used to heat the expansion tube, 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. But if the pressure on the expansion tube increases, so does the cost; Therefore, the working pressure of the hot water pressure washer will be about 200BAR. When you want to use large pressure, you will generally use high pressure cold water cleaning machine to achieve the cleaning effect by its working pressure. When you need to clean oil and various stubborn stains, you need to use hot water high pressure cleaning machine or saturated steam cleaning machine.
