What are the reasons for the insufficient flow of the sewage pump in the integrated pumping station?

2020-04-22
New technology products are emerging, and the maintenance methods are different. However, when you use the integrated prefabricated pumping stations, there will appear some common faults because of different reasons.

What are the reasons for the insufficient flow of the sewage pump in the integrated pumping station? How to eliminate these faults?

Analysis of the reasons for the insufficient flow of the sewage pump in the integrated pumping station:
1. The suction pipe diameter is too small
The integrated prefabricated pumping stations is used mostly for the suction and removal of sewage, so the matching combination of various components in the prefabricated pumping station is also very important. If the configuration performance is insufficient, it will cause various failures or work. In the integrated prefabricated pumping station, if the suction pipe diameter is too small, it will lead to insufficient flow, and the water intake cannot reach the standard. In this case, we only need to change the water inlet pipe and configure a water inlet pipe with a reasonable diameter. 

2. Impeller flow channel is blocked
In the case of impeller flow channel obstruction, we only need to do one step, that is, clean the impeller and discharge the obstruction.


 
3. The head is too high
In many cases, the set pump head is too high, it will also lead to insufficient pump flow, then in this case, you need to open the outlet valve.

4. The speed is too high
Speed is too high, the solution is to restore the rated speed.

5. Impeller is worn or corroded seriously
When the impeller is damaged or corroded seriously and cannot be repaired, the direct method is to replace the impeller.

6. The installed total head is too high or the stream head exceeds the regulations
In this case, you should reduce the head and lower the installation position of the pump to solve.
