What are the maintenance and care measures for sewage pump

Best Practices for Daily Inspection and Operation Monitoring of Sewage Pumps
In the management of sewage pumps, daily inspection and operation monitoring are the core links to ensure the efficient operation of equipment. It is crucial to establish a standardized inspection process, focusing on the operating parameters, vibration noise and leakage of the equipment. Monitor the current, voltage and bearing temperature of the motor daily to ensure that the current fluctuation is controlled within ±10% of the rated value and the bearing temperature is maintained between 60℃ and 80℃. According to statistics from a municipal pumping station, bearing overheating problems found in daily inspections account for 65% of fault warnings. Timely handling of these problems can effectively avoid sudden equipment shutdowns. In addition, regularly use a vibration analyzer to detect the vibration value of the pump body. When the vibration in the vertical or horizontal direction exceeds 4.5mm/s, the rotor imbalance or poor alignment should be checked immediately.
The importance of regular maintenance and component replacement
The regular maintenance of sewage pumps should follow the principle of "prevention first" and establish a scientific maintenance cycle. The leakage of the mechanical seal should be checked every month. If the leakage exceeds 5 drops/minute, it needs to be replaced immediately. When replacing the mechanical seal, special attention should be paid to the fit of the dynamic and static rings to ensure that the end face runout is less than 0.01mm. A pump station failed to replace the worn mechanical seal in time, resulting in sewage leakage and equipment short circuit, which directly caused economic losses of 200,000 yuan.
Key measures for pipeline system maintenance
The impact of the sewage pump pipeline system on equipment performance cannot be ignored. The sealing of the suction pipe and the discharge pipe should be checked every month to ensure that there is no leakage. A pump station caused air to enter due to loose suction pipe joints, causing cavitation, which shortened the service life of the impeller to 1/3 of the normal value. At the same time, regularly clean the sediment and debris in the pipeline to prevent blockage. It is recommended to perform backwashing operations every six months, using high-pressure water flow to remove pipe wall attachments and keep the pipeline unobstructed.
