In order to extend the service life of submersible non-clogging sewage pump, it is very important to do a good job in its maintenance work. How to maintain and maintain the submersible non-clogging sewage pump in daily life? The following is a submersible non-clogging sewage pump maintenance introduction. Submersible non-clogging sewage pump maintenance 1. Pump should be managed and used by special staff, and regularly check the electric pump windings and the insulation resistance between the chassis is normal. 2. Each use, especially for more viscous thicker slurry, the pump should be placed in clean water running for a few minutes to prevent deposits left in the pump to ensure the pump clean. 3. If not for a long time when the electric pump should be removed from the water pump, do not long-term immersion in the water to reduce the motor stator winding damp opportunity to increase the service life of the pump. 4. In the normal state of the pump every 300-500 hours after use should be filled or replace the oil in the oil chamber (10-? 30 No. oil) to maintain a good mechanical seal lubrication, improve the mechanical seal life. 5. After the pump is disassembled and repaired, the housing components must be inspected by 0.2MPa airtight test to ensure the motor seal is reliable. 6. The sealing ring between the impeller and the pump body has sealing function. If the sealing damage will directly affect the performance of the pump, it should be replaced if necessary.
