Repair Method For Loose Impeller Of Submersible Pump

Oct 09, 2024

1, The reason for the loose impeller of the submersible pump
Loose impellers of submersible pumps can lead to a decrease in pump efficiency or malfunction, which may be caused by the following reasons:

1. The submersible pump is subjected to significant impact during operation, causing the impeller and shaft to loosen.

2. Long term use or aging of submersible pumps can cause the impeller to loosen due to excessive clearance between the impeller and shaft.

3. Due to quality issues with submersible pumps, the clearance between the impeller and shaft is not appropriate.

2, Repair method
1. Disassemble the submersible pump

Firstly, it is necessary to stop the operation of the submersible pump and remove the cables. Then, disassemble the submersible pump and remove the impeller for inspection.

2. Clean the impeller and shaft

Clean the impeller and shaft, and remove any oil and sediment from them.

3. Repair the fit between the impeller and the shaft

If the clearance between the impeller and the shaft is too large, glue or silicone can be used to fill it. However, it should be noted that the filling process should ensure that the fit between the impeller and the shaft is aligned. After filling, it is necessary to wait for a period of time for curing.

4. Reinstall

Reassemble the impeller and shaft, and then install the submersible pump back into the water tank.

5. Testing

Restart the submersible pump and conduct testing to ensure stable fit between the impeller and shaft, and that the pump can operate normally.

In short, if the impeller of a submersible pump becomes loose and causes a decrease in pump efficiency or inability to operate, the above methods can be used for repair. But pay attention to safety and operate with caution.
