High pressure cleaning machine is a common cleaning equipment in the cleaning industry, which mainly works by spraying high-pressure water flow through a high-pressure pump. The high-pressure pump is very important in the high-pressure cleaning machine. People who frequently operate the high-pressure cleaning machine may encounter the reason why the high-pressure pump does not produce water. Today, let's learn about the reason?

1. The suction stroke of a high-pressure water pump is relatively large, for example, when placed in a deep water area. When using a high-pressure cleaning machine, we first need to refer to the instruction manual to determine the suction stroke before operating the high-pressure cleaning machine.

2. The rotational speed of the water pump is relatively low. The principle of the water pump itself is that the tightening nut between the impeller and the pump shaft becomes loose or the pump shaft deforms and bends, which can reduce the rotational speed of the impeller of the high-pressure pump, resulting in insufficient power and inability to suction water.

3. The resistance in the water inlet pipe is relatively high, so when using a high-pressure pump cleaning machine for cleaning, we need to ensure that the length and bending of the pipeline are within the operating area.

4. The impeller of the high-pressure pump is severely worn, causing it to be unable to absorb water.

5. The presence of air in the inlet pipe and pump body can cause the inability to absorb water.

The high-pressure pump cleaning machine does not produce water due to these reasons. Regular maintenance and observation of equipment operation are necessary to avoid delaying the cleaning work.
