Optimization of Centrifugal Pump Impeller Outlet Vane Angle by Using Modal Analysis

Hydraulic machine are used in daily life for industrial, farming and much more wide applications. When it is used for various applications that time various working conditions of body itself affect on performance of pump as well as the life of the pump. When we minimize the pumps vibration then it will directly or indirectly improve the performance and life of machine. For that purpose vibration of pump body minimization is very important. In this paper vibration of pump minimize by changing the centrifugal pump impeller outlet vane angle. Initially published two paper shows designing the pump impeller with new angle system, CATIA part analysis in ANSYS workbench which finds out 6 mode of natural frequency of vibration. Here it is shown experimental Result and FFT analysis result of new pumping systems. Which shown Vibration minimize, Performance increasing and mathematically shown life improvement
