Blower inlet casing device for immersible pump

Abstract

The invention provides a submersible pump diversion casing device, which comprises a diversion casing body and a base. The diversion casing body is assembled on the base. The interior of the diversion casing body is set as a cavity structure. The main shaft is provided with a plurality of guide vanes uniformly surrounding along the axial center, the end of each guide vane is fixed on the deflector plate, each guide vane includes a first folded edge, a buffer part and a second folded edge, the second One fold is connected to the main shaft, the second fold is connected to the deflector, and the buffer part is located between the first fold and the second fold. 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 flow, increases the lift of the pump, and improves the service life of the pump.

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.
