Reasons And Solutions For The Impeller Of Submersible Pump Not Rotating

Oct 31, 2024

1, Water inlet blockage

The blockage of the inlet of the submersible pump is one of the main reasons for the inability of the submersible pump impeller to rotate normally. During the use of submersible pumps, it is inevitable that impurities will be sucked in, which will block the inlet and reduce the inlet flow rate, thereby preventing the pump impeller from rotating normally. The solution to this problem is to first stop the operation of the submersible pump and then clean the impurities at the inlet.

2, Motor malfunction

The motor failure of the submersible pump is also an important reason for the inability of the pump impeller to rotate normally. During the use of a submersible pump, if there is a motor malfunction or circuit problem, the submersible pump may not function properly. The solution to this problem is to first check whether the circuit and motor of the submersible pump are normal. If they are not normal, they need to be repaired or replaced.

3, The pump impeller bearing is damaged

Damaged pump impeller bearings are also one of the reasons why submersible pump impellers cannot rotate normally. In the process of using a submersible pump, if it is frequently overloaded, it will accelerate the wear of the impeller bearings, causing the impeller to rotate flexibly or completely unable to rotate. The solution to this problem is to replace the pump impeller bearing.

4, Other reasons

In addition to the above three points, there are other reasons that may also cause the submersible pump impeller to fail to rotate properly, such as pump blade wear, pump shaft bending, etc. If the pump blades are severely worn, new pump blades need to be replaced; If the pump shaft is bent, it needs to be repaired or replaced.

In summary, there are many reasons why the impeller of a submersible pump cannot rotate normally, and the solutions are also different. When repairing a submersible pump, it is necessary to make a judgment based on the specific situation and take corresponding solutions.
