Vibration Analysis of Mixed Flow Pump Impeller Blade Designed Using Mean Stream Line Method

Abstract:

Mixed flow pumps applications have been exploited in a large number of diversified fields of engineering. They find applications as an important component in waste water treatment systems, power stations, irrigation systems etc. User requirements make these pumps to work very close to the functioning requirements and therefore under these conditions the vibrations are bound to occur in different moving components of the pump. It would be difficult to analyse the pump vibrations, considering the pump as a single system. Analysing vibrations in different moving components of the pump will not only be easier but also will aid in reducing the vibrations at the microscopic level. As a subject of the present paper, the mixed flow pump impeller blade has been designed using sparingly used yet accurate mean stream line theory. Modal analysis of the pump blade has been carried out at different modes of frequency. Total deformation for different modes of frequencies has also been determined. Stainless steel has been used as the construction material of the impeller blade.
