摘　　要：屏蔽式电动泵主要是由屏蔽电机部分和泵部分组成。其中屏蔽电机内部是由水循环冷却润滑的。电机转子尺寸大,转速偏高,内部流道复杂。本文使用Fluent软件计算电机内部关键部分的流场分布情况,后期使用Ensight流场后处理软件,对计算出的流场的数据进行可视化处理。了解电机内关键部位流场的速度压力分布规律,并形象展示中部叶轮的增压效果,流场的速度梯度等规律。A kind of canned pump is composed of the motor and the pump section. The canned motor is lubricated and cooled by high pressure water. The rotor in the motor is big and the rotor＇s velocity is high. The water channel inside the motor is complicated. In this article, the software Fluent is used to calculate the fluid field of the key parts in the motor. Then post-processing software Ensight is used to visualize the result of the FEM analysis. The velocity and pressure of the fluid fields in the motor＇s key parts can be studied thoroughly. A video and pictures are created to illustrate the function of the middle impeller and the gratitude of the fluid fields.
