Abstract

The invention discloses an impeller assembly of a guide type sewage pump. The impeller assembly has a cutting function, adopts a closed and open combined structure integrally, and has the advantages of leakage prevention and high efficiency. The impeller assembly is characterized by comprising an impeller, an upper cover plate, a lower cover plate and a plurality of main blades connected between the upper cover plate and the lower cover plate, wherein a shaft sleeve is arranged at the center of the upper cover plate, an impeller wear ring is arranged at the center of the lower cover plate, each main blade comprises an inner end and an outer end, and a cutter is arranged on the inner end of each main blade. The impeller assembly of the guide type sewage pump is suitable for the technical field of sewage pumps.

Description

technical field [0001] The invention belongs to the technical field of sewage pumps, in particular to an impeller assembly of a guided sewage pump. Background technique [0002] The impeller is the main part of the sewage pump and is installed on the pump shaft of the sewage pump. The existing impeller structure mainly includes the following types. Closed impeller: it is composed of blades, front and rear cover plates, and is suitable for conveying clean water, solution and other viscosities. Smaller particle-free cleaning liquids; [0003] The front semi-open impeller is composed of the rear cover and blades, and the rear semi-open impeller is composed of the front cover and blades, which are suitable for conveying clear water and liquids similar to clear water, but the impellers of these two structures have low efficiency; [0004] Open impeller, with only blades and blade ribs, without front and rear cover plates, is used to transport liquids with high viscosity and slur...
