Why is there no pressure in the cleaning machine?

Release time：2019-03-26

　　As people’s quality of life continues to improve, the demands on the quality of industrial cleaning are steadily increasing. With the rapid development of China’s industrial sector and high-pressure cleaning equipment—particularly in heavy-industry applications—it is common for high-pressure washers to experience severely reduced or even zero water pressure after a period of operation, especially under harsh operating conditions. So, what causes a lack of pressure in a pressure washer?

　　If air is present in the inlet water filter of the high-pressure washer, it must be completely purged to ensure that the outlet water pressure meets the specified standard. Additionally, if leaks occur in the high- and low-pressure water seals or the inlet and outlet check valves, resulting in reduced operating pressure, these components should be replaced promptly.

　　Internal malfunctions in the high-pressure pump, such as wear of consumable parts, can lead to reduced water flow; blockages in the equipment’s internal piping can also restrict water flow, resulting in excessively low operating pressure. Insufficient inlet water flow to the equipment further reduces water flow, thereby lowering the outlet pressure. To resolve the issue of reduced outlet pressure, it is essential to ensure a sufficient and steady supply of inlet water flow.
