There are four influencing factors in the cleaning process of high-pressure cleaning machine: pollutants, medium, substrate and cleaning force. So what is the effect of high pressure cleaning machine?
（1） The hydraulic parameters also have a great influence on the cleaning effect.
（2） The working parameters of high-pressure water jet produced by high-pressure cleaning machine directly affect the cleaning effect.
（3） The material properties of the object to be cleaned also affect the cleaning effect.
（4） The degree of grinding and cavitation also plays an important role in the cleaning effect.
（5） High pressure water jet has its own cleaning function, the velocity obtained through the nozzle, the impact force on the object to be cleaned by kinetic energy conversion, and the sum of the joint forces generated by the fluid interface flow on the object to be cleaned, etc.
From this point of view, in fact, there are many factors affecting the cleaning effect of high-pressure cleaning machine, but it does not directly affect our work efficiency. As long as we can grasp the crux of the problem, the cleaning effect will be improved a lot.
