1.Check the self-priming sewage pump pipeline and contact loose appearance. By hand or something tumbling self-priming pump, sewage pump is not sensitive to it.
2.As far as possible to control the flow and head of self priming pump in the range of signs, in order to ensure that the maximum efficiency point of the pump in operation, to achieve the maximum energy saving effect.
3.Since the suction pump in the work process, bearing temperature can not exceed the ambient temperature of 35C, the maximum temperature shall not exceed 80C.
4.Such as the discovery of the abnormal movement of self priming pump should be immediately stopped to check the reasons for.
5.Self-priming sewage pump intermittent use, first closed valve, pressure gauge, and intermittent motor.
6.Self suction sewage pump in a long time to use in the winter season, after stopping the pump body, lower drain plug unscrew medium on the net. Avoid cracking. (if the water is used to clean the pump chamber clean)
7.Listen carefully to work is not static motor disorder, due to the work room of large noise, by using a screwdriver or listen to stick things on both ends of the motor assisted, pro listen, if often listen to, not only can find adverse vibration motor and its driving equipment, even the number of internal bearing oil can distinguish, then timely add bearing oil, disposal or replacement of bearings and the corresponding motor bearing, avoid dry grinding and blocking, go round, sweeping burn.
