Abstract

The invention discloses a self-priming water pump with a filter device. The self-priming water pump comprises a water pump body, wherein a water inlet is formed in one side of the water pump body, and a water outlet is formed in the top of the water pump body; the filter device is arranged on one side of the water inlet and comprises a filter cover, and a sealing ring is arranged in the filter cover; a filter, a filter cup and a water outlet connecting piece are successively arranged at the bottom of the filter cover, and a buckling groove and a buckling hook are respectively arranged the bottom of the filter and the top of the filter cup and are matched with each other. As the self-priming water pump is provided with the filter cup, in the process that a worker cleans the filter, sand cannot drop out from the surface of the filter to enter an impeller again so as to damage a sealing piece, and the service life of the water pump is prolonged. The filter cup with a simple structure can effectively prevent sand from entering the impeller and protect the sealing of the water pump, and the service life of the self-priming water pump is prolonged.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a self-priming water pump with a filtering device. Background technique [0002] At present, there are many types of water pumps on the market, especially self-priming water pumps. If the sucked water contains too many impurities, such as sand particles, the impeller will be blocked, and the sealing device of the impeller is ceramic, and the small sand particles are particularly It is easy to damage the ceramics and cause the water pump to leak.
