Blower inlet casing device for immersible pump

Abstract

The invention provides a blower inlet casing device for an immersible pump. The blower inlet casing device comprises a blower inlet casing body and a base, wherein the blower inlet casing body is assembled on the base; the interior of the blower inlet casing is of a cavity structure; a main shaft is arranged in the cavity of the blower inlet casing; a plurality of guide blades uniformly arranged around the axis are arranged on the main shaft; the tail end of each guide blade is fixed on a guide disk; each guide blade comprises a first edgefold, a buffer part and a second edgefold; the first edgefolds are connected with the main shaft; the second edgefolds are connected with the guide disk; and each buffer part is located between the corresponding first edgefold and the corresponding secondedgefold. The invention aims to provide the blower inlet casing device for the immersible pump, by use of which, the energy loss of water flow is reduced, the lift of the pump is increased and the service life of the pump is prolonged.

Description

technical field [0001] The invention relates to the field of submersible pumps, in particular to a diversion shell device of a submersible pump. Background technique [0002] Most of the submersible pumps rely on the guide shell device installed on it to guide and transport the water flow. The lift of the pump has a great relationship with the energy loss of the water flow. The guide vanes in the prior art mostly use a single Curvature form, such a form cannot meet the flow law of water flow, resulting in a large hydraulic loss of the fluid in the flow channel, which eventually leads to a decrease in the lift of the pump, and due to different operating environments, a lot of sand and stones may enter the pump body, seriously affecting The life of the pump greatly reduces the working efficiency. Contents of the invention [0003] The problem to be solved by the present invention is to provide a submersible pump diverter casing device that reduces the energy loss of water f...
