| 中文摘要: |
| 通过对叶轮结构及其模具的分析，从模具定位方式，叠片方法入手，对叶轮离心浇注模进行了改进设计，增加了定位套和定位压圈，减少原来的叶片隔板，使叶片均匀分布。保证了叶轮叶片与叶轮轴套同心，从而减少了叶轮整体的初始动平衡量，达到减小风机自振动振幅。 |
| 英文摘要: |
| Through the analysis of impeller structure and mould, the centrifugal casting mould of impeller was improved from the mold positioning and lamination method. A locating sleeve and a positioning ring set were added, the original blade diaphragm was reduced so that the blades were evenly distributed. The concentricity of impeller sleeve with the impeller was ensured and the initial dynamic balance amount of the impeller was reduced, which made the vibration amplitude of the fan be reduced. |
