Abstract
In order to predict pump erosion practically, severe erosion is systematically and precisely observed in a typical centrifugal pump of specific speed Ns = 150(m, m3/min, rpm) in various test conditions in relation to types of cavitation, by means of erosion-depth measurements, noise detections, and cavitation-pressure pulse measurements through the paint method as well as the pressure-sensitive film method. The severe erosion directly result from the vortex cavitation, and the erosion rates are closely related to the size and the occurrence frequency of the vortex cavitation.
