A water inlet anti-blocking submersible axial flow pump

Abstract

The invention relates to the technical field of anti-clogging water inlet of a submersible axial flow pump, and discloses an anti-blocking water inlet submersible axial flow pump, which includes a pump body, the right side of the pump body is connected with a water outlet port, the pump The bottom of the body is connected with a water inlet nozzle, and the water inlet nozzle includes a pipe body, and a pipe hole is opened at the bottom of the pipe body, and an annular sealing chamber is opened in the pipe body, and the inner wall of the annular sealing chamber is fixedly connected at an equal angle. There are six electromagnets, and the inner side wall of the annular sealing cavity is movably inserted with six inserting rods at equal angles. The outer circular surface of the inserting rods is fixedly sleeved with a fixed ring, and the fixed ring is connected with the annular sealing cavity. A first spring is fixedly connected between the adjacent sides, and an iron block is fixedly connected at the far-away end of the insertion rod. The invention solves the problems that most existing submersible axial flow pumps are easy to block the outlet filter screens of water inlet pipes, and some submersible axial flow pumps with the function of automatically cleaning the filter screens have poor cleaning effect.

Description

technical field [0001] The invention relates to the technical field of anti-clogging water inlet of a submersible axial flow pump, in particular to an anti-blocking water inlet submersible axial flow pump. Background technique [0002] The submersible axial flow pump has the characteristics of large flow and high head, and is widely used in urban water supply and drainage, irrigation, drainage and other fields. The filter screen is used to filter out the impurities in the water, but as the working time increases, the impurities on the filter screen will gradually accumulate, gradually blocking the flow of water to the pump, reducing the pump water volume, and even causing the axial flow pump to malfunction Work. [0003] An improved submersible axial flow pump is disclosed in the Chinese utility model patent with the authorized notification number CN208749593U. In this submersible axial flow pump, the pump body is connected to the coarse filter by connecting the first sprin...
