Study on the Clearance of Impeller and Draft-Tube on Stamping and Welding Multistage Centrifugal Pump

Abstract:

Based on the Renault-averaged Navier-Stokes equations and a standard turbulence model, the different clearance of the outer edge on the impeller and the draft-tube is simulated by the commercial software CFX, in order to achieve optimal performance. The velocity distributions and pressure distributions within the stamping and welding multistage centrifugal pumps are analyzed. The reasonable clearance value which impact on its performance and properties have been discovered. This paper is helpful to improve the design theory of stamping and welding multistage centrifugal pumps.
