1. Non clogging submersible sewage pump should be managed and used, and regularly check the insulation resistance between the electric pump winding and casing is normal.
2. Each use, especially for thick sticky medium, the electric pump should be put into the water for a few minutes to prevent the pump from leaving the sediment, to ensure the clean water submersible sewage pump.
3. Non clogging sewage pump such as long time should not remove the pump from the water, not long-term immersion in water, in order to reduce the chance of motor stator winding is damp, increase pump service life, to the place where the paint off the paint spraying, to avoid corrosion.
4. In the conventional state sewage pump every 300-500 hours after the filling or replacement of oil room in the oil (10-30 oil), the mechanical seal to maintain a good state of lubrication, improve the service life of mechanical seals.
5. Submersible non clogging sewage pump disassembly, maintenance, chassis components must be by 0.2MPa airtight test, to ensure reliable sealing motor, pump testing should be by clicking on the way to ensure normal and then start the motor.
6. Replace the sealing rings: after used for a long time in water medium, impeller and the seal the gap between the ring may be enlarged, resulting in a decline in the pump flow and efficiency, should turn off the gates, lift the pump and remove the bottom cover and remove sealing ring, according to the impeller mouth ring actual size with sealing ring gaps in general about 0.5mm.
7. Small sewage submersible pump can be used to move the way, the diameter of more than 100mm submersible sewage pump is recommended to use the coupling type installation, so that after the maintenance and detection.
