In order to extend the life of QW submersible sewage pump, QW submersible sewage pump to do the maintenance and repair work is essential, then how to QW submersible sewage pump maintenance and care it? The following describes the QW submersible sewage pump maintenance and repair methods. QW submersible sewage pump maintenance and maintenance 1, electric pump should be managed and used by 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 for a few minutes to prevent deposits left in the pump to ensure the pump clean. 3, If the pump is not used for a long time, it 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 300-500 hours after each 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, pump disassembly and maintenance, the chassis assembly must be 0.2MPa tightness test to ensure that the motor seal is reliable. 6, seal ring between the impeller and the pump body has a sealing function, such as seal damage will directly affect the performance of the pump, if necessary, should be replaced.
