摘　　要：水轮机转轮泵板发生裂纹需对其进行更换改造时,是否需要进行静平衡试验,观点不一。文章分析了泵板改造前静不平衡的影响因素、泵板改造前后的区别,结合实例从泵板质量偏差、泵板与转轮同心度偏差等方面计算了泵板改造后对静不平衡的影响因素以及占比情况,通过定量分析及实际案例实施,找到了泵板改造静不平衡分析的方法、步骤、适用条件,解决了泵板更换改造对静平衡影响大小分析不充分的问题。对后续相关改造分析具有参考价值。When cracks occur on the pump plate of the turbine runner and it needs to be replaced,there are different views on whether static balance test is required.This paper analyzes the influencing factors of static imbalance before and after the pump plate transformation,and the differences between the pump plate transformation and the pump plate transformation.Combined with examples,the paper calculates the influencing factors and the proportion of static imbalance after the pump plate transformation from the aspects of pump plate quality deviation,pump plate and runner concentricity deviation.Through quantitative analysis and actual case implementation,the paper finds out the method,steps and applicable conditions of static imbalance analysis for the pump plate transformation,The problem of insufficient analysis of the influence of pump plate replacement and reconstruction on static balance is solved.It has a good reference significance for the subsequent relevant transformation analysis.
