Horizontal multistage pump low water pressure?

Category: Water pump knowledge

2023-12-05

In the process of using the horizontal multistage pump, the low water pressure is caused by the blockage of the inlet, the leakage inside the pump, the insufficient speed and so on, which affects the normal operation of the pump. Next, Hunan Sanchang Pump Industry will explain to you what to do with the low water pressure of the horizontal multistage pump.

　　

 

Solution for low water pressure of horizontal multistage pump:

　　1. Remove 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, you can remove the filter for cleaning or replacement.

　　2. Replace the impeller or maintenance

If the pump blades are seriously damaged, it is necessary to replace the new impeller or repair the impeller. In addition, regular maintenance and maintenance of the pump can also extend its service life and reduce the frequency of maintenance and replacement.

　　3. Eliminate internal leakage of pump

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

　　4. Increase the pump speed

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

　　5. Check the impeller and pump casing of the pump

The gap between the impeller and the pump casing of the pump is too large or the impeller is damaged, which will cause the pressure to decrease. Ensure that the gap between the impeller and the pump casing meets the design requirements, and replace the impeller or repair the damage of the impeller in time.

　　6. Adjust the axial clearance

During the use of horizontal multi-stage pumps, too large axial clearance will also cause the outlet pressure to drop. Appropriate adjustments can be made to the axial clearance to ensure normal operation.

To sum up, the above is the relevant content of Hunan Sanchang Pump Industry's introduction to users about how to deal with low water pressure of horizontal multi-stage pumps. I hope it will be helpful to you after reading this article. I will continue to pay attention to our website and update your pump knowledge and common faults every day.
