1. Pay attention to the bearing temperature of submersible pump sewage pump, should not exceed the outside temperature of 35 degrees, but the maximum should not be greater than 75 degrees.
2. Cup filled with internal calcium grease, can guarantee the normal lubrication of bearings.
3. Submersible pump sewage pump in the first month of work, or running 100 hours, replace the motor bearing cup butter, later every 2000 hours after the replacement time.
4. Regular inspection of flexible coupling, pay attention to motor bearing temperature rise.
5. In the process of moving, such as the discovery of noise or unusual sound, should immediately stop the inspection.
6. Submersible pump sewage pump every 2000 hours should be periodic inspection, impeller, pump body pump (or cover) between the clearance friction loss can not be too large, clearance of the maximum value shall not be more than 1.5 mm, such as more than replaceable impeller or cover.
7. Submersible pump sewage pump work 6 hours, should check the seal, according to the degree of wear to be repaired or replaced, otherwise it will cause damage to the pump shaft and bearing.
