Causes and solutions of horizontal multistage pump water pressure

In the process of using the horizontal multistage pump, due to the blockage of the inlet, the internal leakage of the pump, the lack of speed and so on, the water pressure is caused by the situation, which affects the normal operation of the pump, and the next Xiaobian will explain to you how to do about the horizontal multistage pump water pressure.

Horizontal multi-stage pump water pressure solution:

1. Remove the blockage

If the pump inlet is blocked, it needs to be cleaned in time, for the blocked debris in the pipeline, you can use tools to remove it, for the pump inlet filter is blocked, you can remove the filter for cleaning or replacement.

2, Replace the impeller or maintain

If the multistage pump blade is seriously damaged, a new impeller needs to be replaced, or the impeller is repaired, in addition, regular maintenance and maintenance of the pump can also extend its service life and reduce the frequency of repair and replacement.

3, Eliminate the internal leakage of the pump

If there is a leak in the multistage pump, it is necessary to find the source of the leak and eliminate it in time, and it may be necessary to replace the seal, check and repair the pump shaft bending and other problems.

4, Improve the pump speed

Increasing the speed of the horizontal multistage pump can effectively improve the water flow and water pressure, but it should be noted that increasing the speed of the pump will also increase energy consumption and noise.

5, Check the impeller and pump shell of the pump

The clearance between the impeller and the pump shell of the horizontal multistage pump is too large or the impeller is damaged, which will lead to the pressure reduction. Ensure that the clearance between the impeller and the pump shell meets the design requirements, and replace the impeller or repair the damage of the impeller in time.

6. Adjust the axial clearance

Horizontal multistage pump in the use of the process, the axial clearance is too large will also lead to a drop in the outlet pressure, can be the axial clearance for appropriate adjustment to ensure normal work.
