Vibration Analysis Of And Experimentation Of Centrifugal Pump Impeller

Impeller is a rotating components of a centrifugal pump. In that the excessive vibration is a good indicator that indicates some damaging phenomenon occurring within an impeller. Mostly machinery problems result from the interaction between an exciting force, associated structural and hydraulic resonance frequencies. When exciting force is stronger at natural frequency the amplitude of vibration becomes maximum. Hence the main objective of this is to carryout vibration analysis and experimentation on various materials to find out alternate suitable material and to minimize the vibration and to improve the performance of pump impeller. To find out the natural frequency of a impeller modal analysis was carried out. Cad model generation was done in CATIA V5, meshing in HYPER MESH and ANSYS is for post processing. Re-analysis and experimentation was done using different material to check the vibration response on the impeller.
