Modeling And Performance Analysis of A Centrifugal Impeller of Water Pump

Abstract

An impeller is a rotating component equipped with vanes or blades used in centrifugal pumps. Flow deflection at the impeller vanes allows mechanical power (energy at the vanes) to be converted into pump power output. Impeller of a centrifugal pump, usually made of iron, steel, bronze, brass, aluminum or plastic, 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. A significant improvement is required for impeller design to resist corrosion, Erosion & weight less. The present work is to design, performance of centrifugal impeller made of Poly-phenylene Sulphide (PPS) and Cast Iron materials and compared the results. Centrifugal impeller is modeled in Solid works, and that model is imported in Ansys-Software, using Ansys-Software we investigated Static and Dynamic behavior of impeller and found that the impeller with Polyphenylene Sulphide (PPS) material is best compared to Cast Iron.
