The hydraulic characteristics of a centrifugal oil pump for pumping viscous liquid at different specific speeds are studied experimentally.The relationship of conversion factor with performance characteristics,rotating speed and oil viscosity is investigated.According to the affinity law proposed by KSB,the performance diagram of flow rate,head and efficiency is plotted at five different specific speeds.The typical calculated examples show that the calculated results with the diagram methods are consistent with the experiments.
