What needs to be done for dirty water submersible pump?

The dirty water submersible pump is a key link to ensure the long-term stable operation of the equipment, and must be carried out persistently. Operators need to pay close attention to the operating status of sewage submersible pumps, especially the current, voltage, vibration and noise of the pump body, which can intuitively reflect whether the equipment is in the normal working range.

It is very important to regularly clean the grilles and debris in the sump or pump pit to prevent foreign objects such as garbage and fibers from clogging the impeller or winding the pump shaft, thereby causing damage to the sewage submersible pump or even jamming and stopping the pump. At the same time, be sure to pay attention to and remove ropes, plastic bags and other entanglements wrapped around the outside of the pump body. It is essential to check the integrity of the power cable and control cable. Any wear, aging or rupture must be handled immediately to prevent leakage accidents. The inspection of the sealing system should not be ignored. It is necessary to observe whether there are signs of leakage in the mechanical seal or oil chamber, and ensure that the oil volume in the sealing oil chamber is sufficient and there is no obvious emulsification. This is the key line of defense to prevent water from entering the motor and damaging the windings. The running sound and temperature of the bearing also need to be monitored regularly. Abnormal temperature rise or abnormal noise is often a precursor to failure.

In addition, checking whether the anti-corrosion coating on the surface of the pump body is intact and repairing the damaged parts in time can effectively slow down the corrosion rate. After each maintenance work is completed, detailed inspection results and treatment measures should be recorded. It is particularly important that before any cleaning, inspection or maintenance of the sewage submersible pump, the power-off and tag-out procedures must be strictly implemented to confirm that the equipment is completely stopped and reliably isolated from the power supply before operation to ensure personal safety.

After the maintenance is completed, the power-on test run should be carried out as required, and the pump should be carefully observed to see whether it starts smoothly, runs smoothly, and whether the flow pressure is normal. Confirm that the dirty water submersible pump has returned to a good state before it can be put back into daily drainage tasks. Adhering to standardized maintenance can significantly improve equipment efficiency and life.
