How should sewage pumps be maintained?

Regular cleaning: Regularly clean the outer surface of the pump and the surrounding environment, remove debris and dust around the pump, and ensure that the pump is well ventilated.
Check the liquid level: Check the liquid level at the inlet and outlet of the pump regularly to ensure that the water inlet of the pump is not blocked and the water outlet does not leak.
Check electrical components: Regularly check electrical components such as motors, wires, terminal blocks, etc. to ensure that electrical connections are firm to prevent leakage and fire.
Lubricating components: Regularly add lubricating oil to the bearings, seals and other lubricating components of the pump to maintain the normal operation and sealing performance of the components.
Check the mechanical seal: Regularly check the mechanical seal components of the pump, such as shaft seals, sealing rings, etc., to ensure that the seals are not damaged or leaking.
Clean the filter: Clean the water inlet filter of the pump regularly to prevent the filter from becoming clogged and affecting the normal operation of the pump.
Check the pump body: Regularly check the pump body, impeller and other components to ensure there are no wear, cracks or deformations.
Pay attention to vibration and noise: Check the operating status of the pump regularly, observe whether there is abnormal vibration and noise, and troubleshoot in time.
Regular maintenance plan: Develop a regular maintenance plan, carry out maintenance and upkeep work according to the plan, and ensure that every maintenance link is implemented.
Record maintenance status: Regularly record the maintenance status and operating parameters of the pump, and establish maintenance files to provide reference for subsequent maintenance work.
