Novel front guard plate sealing structure

The utility model relates to the technical field of water pump sealing, and provides a novel front guard plate sealing structure which comprises a pump shell with a cavity and an impeller rotationally arranged in the pump shell, a front guard plate is arranged in the pump shell, an axial gap is formed between the impeller and the front guard plate, a plurality of through holes are formed in the front guard plate, and the front guard plate and the pump shell form a sealing water cavity. The through hole is communicated with the axial gap and the sealing water cavity, and a flushing water pipe is arranged at the sealing water cavity of the shell in a penetrating mode and used for supplying water to the sealing water cavity. The problem that the impeller and the front protective plate are abnormally abraded due to the fact that impurities between the impeller and the front protective plate are not easy to clean in the prior art is solved. 本实用新型涉及水泵密封技术领域，提出了一种新型的前护板密封结构，包括具有空腔的泵壳和转动设于泵壳内的叶轮，泵壳内设有前护板，叶轮和前护板具有轴向间隙
