Water pump parts are mainly water pump impeller, water pump mechanical seal, shaft sleeve, pump shaft, pump bearing body, shaft coupler, bearing, bearing gland, flat cross ring, rotor, shaft coupler, pump body, oil chamber, sealing and so on.
Before the pump is started, the pump and the inlet pipe are filled with water, after the pump is running, under the action of centrifugal force produced by the high-speed rotation of the impeller, the water in the impeller channel is thrown around and pressed into the worm shell, the inlet of the impeller forms a vacuum, and the water in the pool is sucked in to replenish the space along the suction pipe under the pressure of the outside atmosphere. Following the inhalation of water and impeller thrown out by the worm shell and into the outlet pipe.
It can be seen that, if the centrifugal pump impeller rotates continuously, the water can be sucked continuously, water pressure, water can be constantly raised from the low to the high or far away. In summary, centrifugal pumps are due to the role of centrifugal force generated by the high-speed rotation of the impeller, the water will be lifted to a high place.

Precautions:
1, if the pump has any minor faults remember not to let it work. If the pump shaft packing finish wear and tear to be added in time, if you continue to use the pump will leak. This brings the direct impact of the motor to increase energy consumption and will damage the impeller.
2, if the pump in the process of using a strong vibration this time must stop to check what is the reason, otherwise the same will cause damage to the pump.
3, when the pump bottom valve leakage, some people will use dry soil into the pump inlet pipe, water to the bottom valve, this practice is really not desirable. Because when the dry soil into the inlet pipe when the pump starts to work these dry soil will enter the pump, then it will damage the pump impeller and bearings, this shortens the life of the pump. When the bottom valve leaks must be taken to the repair, if very serious then need to replace the new one.
4, the pump must pay attention to maintenance after use, for example, when the pump is used up to put the water in the pump clean, it is best to be able to remove the water pipe and then rinse with water.
5, the water pump on the tape should also be removed, and then rinsed with water in the light after drying, do not put the tape in a dark and damp place. The tape of the water pump must not be stained with oil, not to mention the tape coated with something sticky.
