Optimization Analysis of Cooling Structure for Meshing Rotor of Mixer Based on Creo Parametric Software

采用Creo Parametric软件建立密炼机啮合型转子的热分析模型,对转子的冷却结构进行优化分析。结果表明:“分体式+螺旋管道”冷却结构对转子有很好的冷却效果,分体式冷却结构可使转子的主体及凸棱冷却更均匀,螺旋管道冷却结构可以增大冷却水流面积和流速,冷却效果较好;与单螺旋冷却结构转子相比,双螺旋冷却结构转子的凸棱壁厚度和温度场分布更均匀,凸棱顶部最高温度较低。

The thermal analysis model for the meshing rotor of the mixer was established based on Creo Parametric software,and the cooling structure of the rotor was optimized.The results showed that the“split type+spiral pipe”cooling structure had a good cooling effect on the rotor,the split type cooling structure could make main body and convex of the rotor more evenly cooled,and the spiral pipe structure could increase the cooling water flow area and flow rate,with a good cooling effect.Compared with the rotor with single spiral cooling structure,the convex wall thickness and temperature distributions of the rotor with double spiral cooling structure were more uniform,and the convex top maximum temperature was lower.
