Effect of Spiral Tube Arrangement on Temperature Field of Canned Motor for Nuclear Pump
The maximum temperature of main components of a canned motor is the key factor affecting the safe and stable operation of the canned motor.Especially for a canned motor with built-in spiral tube, the arrangement of spiral tube will have a great influence on the temperature field of the canned motor....

| description | The maximum temperature of main components of a canned motor is the key factor affecting the safe and stable operation of the canned motor.Especially for a canned motor with built-in spiral tube, the arrangement of spiral tube will have a great influence on the temperature field of the canned motor.In this paper, the physical model of cooling canned motor with built-in spiral tube was established and its internal spiral tube was arranged into two ways of staggered and parallel.Then, the temperature fields of the canned motor under two different arrangements were numerically simulated and contrastively analyzed by the finite volume method based on the CFD principle.The temperature distribution of the motor casing and the primary and secondary water shows the characteristics of low temperature in the upper part and high temperature in the lower part.The heat transfer of cooling water in the arrangement of staggered of double-layer spiral tubes is greather than that in the arrangement of parallel, and the overall average temperature of the canned motor is higher. It provides a reference for the selection of the layout of the built-in heat exchanger arrangement of the canned motor. |
