First of all, we need to understand the common faults and causes of submersible sewage pumps.
For example, if a submersible sewage pump fails to start or operates erratically, it may be caused by power connection problems, motor failure, damaged cables, etc.
In addition, insufficient flow and head of the submersible sewage pump may be caused by impeller wear, seal aging, etc. To address these problems, we can take the following measures to repair them:
Check the power connection: During the maintenance process, first check whether the power connection is firm and whether the cable is damaged. If there is a problem, it should be repaired or replaced immediately to ensure stable power supply.
Check for motor failure: If the submersible pump fails to start or runs erratically, you need to check for motor failure. You can check whether there is any damage or abnormality inside the motor through visual inspection, touch, etc. If there is a problem, the motor needs to be replaced or repaired.
Check the cables: The condition of the cables is critical to the proper operation of the submersible pump. It is necessary to check whether the insulation layer, shielding layer and conductor part of the cable are intact. If it is damaged or aged, it should be replaced or repaired immediately to avoid overloading or overheating of the motor due to cable problems.
Check the seals: The seals of the submersible pump may wear or age after long-term use, resulting in a decrease in sealing performance. To avoid leakage or seepage problems, seals should be replaced regularly to ensure they have good sealing performance.
Check the impeller: The impeller is one of the important parts of the submersible pump, and its wear may affect the flow and head of the submersible pump. The impeller needs to be checked for wear, deformation or loss. If there is any problem, it needs to be replaced or repaired.
Check the bearings: The bearings of the submersible pump may be worn or damaged after long-term use, causing abnormal operation. The lubrication of the bearings needs to be checked, and if there is any problem, it needs to be replaced or repaired.
