Abstract:In this paper the pump features of a single screw pump for transferring liquids with different viscosity are experimentally studied. The test results show that the pump features are changed with different viscosity of liquid. In the conditions of the experimental viscosity regions and the same pressure, flow rate increases, axial power decreases and pump efficiency rises with a rise in viscosity. The pump feature curves have been analyzed. The influencing factors of liquid viscosity on the pump features and the pump cavitation features are discussed. The cavitation feature curves in different medium are analyzed. It proved that the single screw pump should be prevented from working in the condition of cavitation.
Keywords:Screw pumps  Viscosity  Experiments  Characteristic curve  Pumping units
