一种水环真空泵叶轮的结构设计与分析
Structure Design and Analysis of an Impeller for Water Ring Vacuum-pump

根据6500 m3/min巨型水环真空泵的总体设计思想,对叶轮给出了具体设计。通过理论和经验方法计算出叶轮的总体尺寸,保证所设计叶轮能够满足排量要求。对该叶轮进行三维建模、强度刚度分析以及模态分析,确认工作时强度刚度是否足够。接下来,通过计算分析对叶轮的一些尺寸参数进行了优化,使叶轮在满足工作需要的条件下质量尽可能的减轻,进而降低了生产成本。通过上述设计分析,既完成了该叶轮的设计,又使叶轮设计在一定程度上摆脱对经验的依赖。
According to the overall design idea of 6 500 m3/min displacement giant water ring vacuum-pump, we carried on the specific design of the impeller. Theoretical and experiential methods were used to design the total size of the impeller in order to satisfy the requirement of displacement. The model was built with ANSYS software and the strength, stiffness and modal analyses were conducted so as to confirm whether the strength and stiffness is enough. Then size optimization was performed for the impeller to reduce the weight and production cost while the work conditions were satisfied. The proposed design and analysis can relieve the dependence of experience on impeller design
