The higher the pressure of the high-pressure cleaner, the higher the performance of the component and the tightness of the device, and the corresponding increase is required. As a result, the cost is increased. Once the pressure is too high, when the jet is sprayed onto the surface of the cleaning object, it is likely to cause splashing of water, which will cause adverse effects on the cleaning work. As a result, the water pressure will be offset and the water will be atomized. As a result, the cleaning efficiency is not only reduced, but also the cleaning effect is not ideal. The pressure required for high-pressure cleaning should be comprehensively considered according to the specific requirements of the work and the nature of the dirt on the surface of the cleaning object and the degree of cleaning. The required pressure is scientific and reasonable. Nowadays, when the high pressure washer machine motor is cleaned, the required pressure is determined by the experimenta...
