Design and Analysis of Impeller for Centrifugal Pump

Mechanical Engineering

The aim of this paper is to design the impeller for a centrifugal caustic slurry pump to increase its power and efficiency, and showing the advantage of designing parameters (six blade turbine ,design changes from impeller) comparing with the old material of a TURBINE. An investigation in to usage of new materials is required. In the present work impeller was designed with two different materials. The investigation can be done by using SOLIDWORKS and ANSYS software. The SOLIDWORKS is used for modeling the impeller and analysis is done in ANSYS. ANSYS is used for determining the variation of heat flux and directional deformation across profile of the impeller. Several attempt has been made to investigate the effect of temperature, pressure and induced stresses on the impeller. By identify the true design feature, the extended service life and long term stability is assured is defined. A thermal analysis has been carried out to investigate the heat flux and direction heat flux of the impeller is defined. An attempt is also made to suggest the best material for an impeller of a turbine by comparing the results obtained for two different materials inconel alloy 783 and inconel alloy 740 for centrifugal force is to made it. Based on the results best material is recommended for the impeller of a turbocharger.
