Inflow and outflow water body of pump shaft locating-free inflow and outflow water body structure

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.
