Analysis on the Cavitation Behaviour of a Semi-Closed Impeller operated Centrifugal Pump with varying Axial Clearance
Machines that cater the everyday needs of mankind tend to be of inevitable and the researches that focus on improvements on such unique machinery are never ending. One among such machines is a pump that is ineludible for household, industrial, and automobile applications. Centrifugal pump is one such category. The type of impeller being used in centrifugal pump and also the contour of the casing adapted plays a hefty role in its performance. In an attempt to modify the contour of the casing and combine it with a semi-closed impeller, this research work has progressed in design and experimental analysis. A semi-closed impeller type centrifugal pump was designed with a tailor-made annular casing and the axial clearance of the pump was made the key parameter in the experimental analysis. This research work is hence an experimental analysis that would possibly conclude an optimum axial clearance that would maximize the performance
of the centrifugal pump. Performance plots were recorded for three axial clearance cases and a comparison has been conferred from the cases.
