A high-pressure cleaning machine is a machine that uses a high-pressure plunger pump to produce high-pressure water to flush the surface of the object. It can peel away the dirt, and wash away, to clean the surface of the object. Because it is the use of a high-pressure water column to clean dirt, so high-pressure cleaning is also recognized as one of the most scientific, economical, and environmentally protected cleaning ways.
It can be divided into cold water high-pressure cleaning machine, hot water high-pressure cleaning machine, motor driven high-pressure cleaning machine, gasoline engine driven high-pressure cleaning machine, etc
The hot water washer adds a heating device that uses a combustion cylinder or an electric heating device to heat the water. However, the price of hot water cleaning machine is high and the operation cost is high (because of to use of diesel or electricity to heat the water), so many professional customers will choose a hot water cleaning machine.
According to the drive engine divide, motor drives high-pressure cleaning machines, gasoline engine drive high-pressure cleaning machines， and diesel oil drive cleaning machines are three categories. As the name suggests, these three cleaning machines are equipped with high- pressure pumps. The difference is that they are connected to the motor, gasoline engine， or diesel engine to drive the high-pressure pump to operate. The advantage of gasoline-powered high-pressure cleaners and diesel-powered cleaners is that they can work in the field without power.
According to the use of the points, household, commercial，and industrial use of three categories. First, in the household high-pressure cleaning machine, the general pressure, flow，and life are relatively low (generally less than 100 hours), the pursuit of portable, flexible movement, simple operation. Second, commercial high-pressure cleaning machine, higher requirements on parameters, and the frequency of use, long use time, so the general life is longer. Third, the industrial high-pressure cleaning machine, in addition to the general requirements, there will often be some special requirements, water cutting is a good example.
