Submersible pump fault detection

Submersible pump fault detection

If the submersible pump you are using is insufficient for fluid delivery, there may be more than one reason for this situation. The outlet valve may be closed or the discharge pipe may be damaged. In addition, the strainer forming the suction port connection may be clogged, all of which may cause submersible pump failure. If the submersible pump head is insufficient, this may indicate that the well water level is low. As we mentioned above, submersible pumps are designed not to be exposed to external factors, but the necessary preliminary safety and precautions should be taken against a possible leakage. Let’s continue with submersible pump failures. In addition to the ones mentioned above, we can list a few of the submersible pump malfunctions as follows;
• Pump or check valve may be clogged. In this case, you have to remove the pump from the well and repair it.
• It is possible that the pump is operating at very low speed. You may need to check for undervoltage or unbalance.
• There may be a leak in the installation. It requires a good review in all respects.
• Shaft or coupling may be broken. Check the pump out of the well or replace the shaft or coupling if necessary.
• The pressure switch may be faulty or its settings may be incorrect.
• Pump impellers may be clogged, in this case it is recommended to take the pump out of the well and check it.
• If the thermal protection system is activated, then you may need to clean the suction strainer, pump elements or check valve because the pump may be blocked.
• If the pump is noisy and this indicates an unusual situation, then the possibility of clogged pump elements should be considered.
