[0002] A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the liquid energy. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. There are centrifugal pumps, axial flow pumps and mixed flow pumps. Self-priming centrifugal pumps are a type of centrifugal pump. They have high sealing performance and large suction range, and their self-priming capacity can reach more than 9m water column.

[0003] Existing water pumps such as (application number: CN202410501822.1) disclose a high-sealing large-suction-range water pump, which belongs to the field of water pump technology. In order to solve the technical problem that the operation of filling the pump multiple times when the existing self-priming centrifugal pump needs to be used for a long time interval is cumbersome and inconvenient to use, the water pump drives the motor to rotate at a lower speed for a period of time, so that the first flow hole and the second flow hole overlap, fill the pump casing, and then rotate the drive motor at a higher speed, so that the impeller drives the water to form a stable conveyance. At this time, the driving gear also rotates at a high speed, so that the second flow hole is blocked, and part of the water flowing in the water outlet can enter the water storage tank, and the particles and impurities in the water are filtered by the filter plate. However, the water pump has the problems of complex design and excessive waste of materials. Utility Model Content
