High pressure cleaning machine does not absorb water how to return a responsibility?

Time: July 9, 2020 14:22 source: unknown author: admin

In the long-term operation of the high-pressure cleaning machine, some work faults are inevitable. When the high-pressure cleaning machine fails, the operator should carefully find out the causes according to different fault phenomena and solve the problem in time. Here we mainly introduce how the high pressure cleaning machine does not absorb water.

 High pressure cleaning machine

1. After the high-pressure cleaning machine is started, the water is unstable, or sometimes not

1. Air is drawn into high-pressure water pump or water inlet pipe. At this time, we only need to trigger the high-pressure water gun to reduce the working pressure of the high-pressure cleaner and run for a period of time until a stable pressure is generated.

2. Insufficient water supply. At this time, please check whether the water pressure is sufficient. Some high-pressure cleaners have no self-priming function. At this point, a booster pump can be added to solve the problem.

3. If the water supply filter is blocked, just clean the water supply filter.

II. The high pressure cleaning machine cannot reach the rated pressure of the equipment

When the high-pressure cleaning machine is running, there is a certain working pressure, which does not reach the rated pressure of the equipment, or the pressure is only kept in a certain range and cannot be increased. In this case, first check whether the diameter of the high-pressure nozzle matches, and if not, match with the replacement high-pressure nozzle. Next, check that the pressure regulator is adjusted to the correct position. If the pressure can not be eliminated in both cases, then check whether the internal sealing components (O-ring, water seal) of high-pressure pump are intact and whether the piston is damaged. If the piston is damaged, repair is required.

3. After a period of normal operation, the pressure of the high-pressure cleaner will decrease

1. Check whether the high pressure nozzle is seriously worn. If the wear is serious, replace the high pressure nozzle. The high-pressure nozzle of small pressure equipment is basically not worn, because the high-pressure nozzle we equipped is basically heat-treated, but it is difficult to ensure the high-pressure nozzle of large-scale pressure equipment.

2. Check whether the inlet filter is blocked. If the inlet filter is clogged, remove the filter and flush with water. If the external water filter is not blocked by clean water, please replace it frequently.

3. Check the sealing parts in the pressure regulating valve, relief valve and high-pressure water pump, such as whether the O-rings of the pressure regulating valve and relief valve are worn, whether the spring and valve seat are worn, whether the surface is worn, whether the O-ring in the pump is worn, whether the water seal is damaged, whether the check valve is worn or filled with foreign matters.
