Title: Influence of Pump Impeller Diameter on the Hydraulic Characteristics of Low Head Pump System
Abstract: The hydraulic loss of conduit in both vertical pump system and bulb tubular pump system were calculated using the numerical simulation,and the influence of pump impeller diameter on hydraulic loss of conduit was analyzed.Based on the similitude rules of impeller pump,the relationship between pump impeller diameter and nD value and the influence of pump selection and design were analyzed.It is could be concluded that the larger pump impeller diameter may obviously increase the efficiency of both conduit and pump system;increasing pump diameter and decreasing its rotational speed is consistent with reducing nD value.It is suitable to pump system with low head to choose lower nD value,so as a hydraulic model of axial flow pump with the better hydraulic characteristics could be obtained.
