Design and Analysis of Impeller Angle Change

In this study, dynamic analysis of an impeller with load on each paddle was performed by using FEM. The commercial finite element package ANSYS version 14.5 was used for the solution of the problem. An impeller is a rotating component of a pump, made of gun metal which transfers energy from the motor that drives the pump to the fluid being pumped by accelerating the fluid outwards from the center of rotation. The velocity achieved by the impeller transfers into pressure when the outward movement of the fluid is confined by the pump casing. Impellers are usually short cylinders with an open inlet (called an eye) to accept incoming fluid, vanes to push the fluid radially, and a splined, keyed or threaded bore to accept a drive-shaft. The optimization of impeller angle of 350, 400 and 450, taking into consideration of forces acting on each paddle of the impeller, the deformation, strain and stress are tabulated. And here we are studying about the impeller as well as developing our skills in software like Creo and Ansys.
