Problems solved by technology

[0002] In the existing stainless steel multi-stage centrifugal pump, the pump shaft fixing structure is provided at the center of the water inlet and outlet. The smooth technical requirements of the fluid at the suction inlet of the pump are inconsistent with the flow velocity between the internal impeller, which affects the efficiency of the whole pump
Moreover, there is a boss at the inlet and outlet of the water body, which makes the inflow liquid flow smooth.

Abstract

The invention belongs to the technical field of water pump tools, and particularly relates to an inflow and outflow water body of pump shaft locating-free inflow and outflow water body structure. The inflow and outflow water body of the pump shaft locating-free inflow and outflow water body structure comprises a main body, a first seam allowance and a second seam allowance are formed in the upper end face of the main body and are simultaneously formed through one-time clamping and machining, a water inflow guide blade is arranged above the first seam allowance and is matched with the first seam allowance, the second seam allowance is connected with an outer cylinder matched with the second seam allowance, and the water inflow guide blade is arranged in the outer cylinder. The water body has the advantages that coaxiality of a pump shaft can be guaranteed, and inflow water at a water inlet of a pump flows smoothly.

Description

technical field [0001] The invention belongs to the technical field of water pump appliances, and in particular relates to a structure for entering and exiting a water body without positioning of a pump shaft. Background technique [0002] In the existing stainless steel multi-stage centrifugal pump, the pump shaft fixing structure is provided at the center of the water inlet and outlet. The smooth technical requirements of the fluid at the suction inlet of the pump are inconsistent with the flow velocity between the internal impeller, which affects the efficiency of the whole pump. Moreover, there is a boss at the entrance of the water body, which makes the water inlet liquid flow smooth and smooth. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems, and to provide a water inlet and outlet water structure with no positioning of the pump shaft, which can not only ensure the coaxiality of the pump shaf...
