Abstract: ic drive pump has gotten great achievement and has been widely used磅,段后回车换行 1 次字号 8 in some special fields. Currently, the researches on ic drive pump have focused on hydraulic design, bearing, axial force in China, and a new ic drive pump with low flow and high head have been developed overseas. However, low efficiency and large size are mon disadvantages for the ic drive pump. In order to study the performance of high-speed ic drive pump, FLUENT is used to simulate the inner flow field of ic drive pumps with different rotate speeds, and get velocity and pressure distributions of inner flow field. According to analysis the changes of velocity and pressure to ensure the stable operation of pump and avoid cavitation. Based on the analysis of velocity and pressure, this paper presents the pump efficiency of ic drive pumps with different rotated speeds by calculating the power loss in impeller and volute, hydraulic loss, volumetric loss, mechanical loss and discussing the different reasons of power loss between the ic drive pumps with different rotated speeds. In addition, the ic drive pumps are tested in a closed testing system. Pressure
