Abstract

For the axial pumps, the inlet bend of 90° affect widely the prerotation, losses and the pump performance as well. A stabilzing plate has been placed in the entrance bend, in the plane of curvature, to minimize these effects. Experimental investigations have been carried out for the pumping head, power and cavitation characteristics. It has been found that the stabilizing plate improves the pump performance at normal and higher flow rates. At partial discharges, the results showed that the pump performance is lower due to supplementary losses due to plate. The cavitation ability has been found to be improved at normal and higher flow rates.
