Abstract This program is a design for the single-stage and single-suction centrifugal pump based on the parameters of IS100-80-160 pump. Using traditional design methods designed the centrifugal single-stage single-suction cantilever centrifugal pump,during which some of the parameters is determined by use of the Matlab toolbox, Excel, to achieve direct and rapid results. The design of the main components, a cylindrical blade design selected way to determine the parameters of the core components of the impeller, a flow channel for in-spection, calibration of the impeller axial plane projection of the contour curve, then the design of the impeller the vortex chamber, according to the need to select a conical suction chamber, in order to determine the pressing, extruding chamber determines the structure of the pump cover and pump body and checking the pump cavitation resistance. Completed shaft design and strength check of each of the major components for the main pump selec-tion and calculation of common parts. With Solidworks modeling, and draw the pump as-sembly diagrams and impeller, pump casing, pump parts diagram of major components. Using Fluent,the fluid simulation software complete the two-dimensional flow field simu-lation, get the diagram speed of the pump chamber and pressure distribution.
Keywords： centrifugal pumps, single stage single suction, strength check, fluid si-mulation
