INVESTIGATION ON PERFORMANCE CONVERSION OF CENTRIFUGAL OIL PUMPS USED IN CHINA

摘要

A series of performance tests with different specific speeds (40, 50, 80, 90 and 130) were carried out on centrifugal oil pumps used in China's oil industry under different conditions of liquid viscosities (1-300mm~2/s) and pump rotating speeds (1000-3000rpm). The effect of viscosity on centrifugal oil pump performance and cavitations characteristic has been investigated. By considering the effects of flow rate viscosity and pump design parametric such as impeller outlet diameter and outlet width on the pump cavitations characteristics, a new performance and cavitations conversion correction factor diagram was plotted.
