Abstract

Change the clearance between the outer edge of the impeller and the draft tube to get a good performance, simulated by the commercial software CFX of CFD. The paper numerically calculates the flow of stamping and welding multistage centrifugal pumps, forecasts its properties, studies the changes which impact its performance in space, gets the reasonable scope of space for stamping and welding multistage centrifugal pumps. It provides a theoretical basis for the design of stamping and welding multistage centrifugal pumps, improves the performance of the centrifugal pump in practical application, increases the operating efficiency of the pump.
