A high-pressure cleaning machine is a cleaning equipment that uses a power device to generate high-pressure water from a high-pressure plunger pump to flush the surface of an object. The impact force of the water is greater than the adhesion between dirt and the surface of the object. The high-pressure water will peel off and wash away the dirt, achieving the purpose of cleaning the surface of the object. Because the high pressure water column is used to clean the dirt, it is necessary to add a little detergent unless it is very stubborn oil stains. Otherwise, the foam generated by strong water pressure is enough to take away the general dirt. Therefore, high pressure cleaning is also recognized as one of the most scientific, economic and environmentally friendly cleaning methods in the world. According to the outlet water temperature, high-pressure cleaning machines are divided into two categories: cold water high-pressure cleaning machines and hot water high-pressure cleaning machines. The biggest difference between the two is that a heating device is added to the hot water cleaning machine, which usually uses a combustion cylinder to heat the water. Using hot water to clean can quickly remove a large amount of dirt and oil stains that are not easily rinsed with cold water, greatly improving cleaning efficiency. However, often due to the high price and operating cost of hot water cleaning machines (due to the use of diesel), most users may choose ordinary cold water high-pressure cleaning machines; Of course, in order to improve cleaning efficiency and effectiveness, many professional customers will choose hot water cleaning machines. According to the driving engine, there are three major categories: electric motor driven high-pressure cleaning machines, gasoline engine driven high-pressure cleaning machines, and diesel driven cleaning machines. As the name suggests, these three cleaning machines are all equipped with high-pressure pumps, but the difference is that they are respectively connected to an electric motor, gasoline engine, or diesel engine to drive the high-pressure pump operation

Hot water high-pressure cleaning machine operation. The advantage of gasoline engine driven high-pressure cleaning machines and diesel engine driven cleaning machines is that they can operate in the field without the need for power. Classified by purpose, there are three major categories: household, commercial, and industrial use. Firstly, household high-pressure cleaning machines generally have lower pressure, flow rate, and lifespan (usually less than 100 hours), pursuing portability, flexible movement, and simple operation. Secondly, commercial high-pressure cleaning machines have higher requirements for parameters, are frequently used, and have a longer lifespan. Thirdly, in addition to general requirements, industrial high-pressure cleaning machines often have some special requirements, and water cutting is a good example.
