1. The self-priming pump is lubricated with high-quality calcium-based butter and No. 10 oil according to the working condition of the pump. If the pump is lubricated with grease, the grease should be regularly added to the bearing housing. If the pump is lubricated with oil, if it is used. If the oil level is insufficient, it will be added.
2. Check whether the liquid in the pump casing is higher than the upper edge of the impeller. If it is insufficient, the liquid can be injected directly into the pump body from the filling port on the pump casing, and should not be started in the case of insufficient liquid storage. Otherwise the pump will not work properly and the mechanical seal will be damaged.
3. Check if the rotating parts of the ZX type clean water self-priming pump are stuck with magnetic collision.
4. Check the nut of the pump body and the nuts at the joints for looseness.
5. Check the coaxiality and parallelism of the pump shaft and the motor shaft.
6. Check the inlet pipe for leaks. If there is a leak, you must try to eliminate it.
7. Open the valve of the suction line. Open the (not fully open) outlet control valve.
