After long-term operation, the Sewage pump needs effective maintenance to ensure its stable performance and extend its service life. Here are some key maintenance measures:
First, regular inspection is essential. The appearance of the Sewage pump should be checked for corrosion, wear or cracks. At the same time, check whether the cable is damaged, aged or the joint is loose. For example, if the cable sheath is found to be worn, it should be wrapped or replaced in time to prevent leakage accidents.
Inspection of the inside of the pump body is also very important. Disassemble the pump body and check the wear of the impeller, sleeve, seal and other parts. If the impeller is severely worn, it will affect the pumping efficiency and needs to be replaced in time. For parts with less wear, they can be repaired or polished.
Regular cleaning is one of the key steps in maintenance. Sewage often contains impurities and sediments, which will clog the pump body and pipelines over a long period of time. It is necessary to clean the dirt and debris in the pump casing, impeller and flow channel to ensure smooth water flow. For example, you can use a high-pressure water gun to rinse or chemical cleaning agents to remove stubborn dirt.
The maintenance of mechanical seals cannot be ignored. Check the wear of the sealing surface. If there is leakage, the seal should be replaced in time. At the same time, ensure that the seal is well lubricated to reduce friction and wear.
Bearing maintenance is also crucial. Regularly add or replace the appropriate amount of lubricating oil to reduce bearing wear, reduce operating noise, and improve operating stability. If abnormal noise or overheating of the bearing is found, the machine should be stopped immediately for inspection.
Motor maintenance is equally important. Check whether the motor wiring is firm and measure the insulation resistance of the motor to ensure that the motor is operating normally and there is no risk of leakage.
In addition, regular testing of the performance of the Sewage pump is also part of maintenance. By measuring parameters such as flow, head and power, and comparing them with the initial performance data, the operating status of the pump can be judged. If the performance decreases significantly, the cause should be found and repaired or adjusted.
During the maintenance process, records should also be kept, including the time, content, and parts replaced, so as to track the maintenance history of the equipment and provide a reference for subsequent maintenance and repairs.
In short, the maintenance of the Sewage pump after long-term operation needs to be comprehensive, detailed and regular. Only in this way can we ensure that the sewage pump is always in good operating condition and provide reliable support for sewage treatment work.
