摘要
阐述了叶轮单体进行动平衡校正的必要性,分析了采用磨削去除叶轮不平衡量的缺点,简介了叶轮的平衡校正原理,通过对叶轮不平衡量进行环带换算,并利用数控铣床进行铣削的研究,总结出提高叶轮表面平衡去重质量和效率的一种有效的方法。
The paper specifies the necessary of transient equilibrium adjustment for single impeller and analyzes the disadvantage of adopting grinding method to erase unbalanced quantity of impeller. Furthermore, the balanced adjustment principle of impeller is also introduced in this paper. An effective method for improving the mass and efficiency in impeller surface balance is concluded, which is based on the annulus conversion with impeller unbalanced quantity and the research on milling by using numerical control machine.
