| 摘 要： | 通过对一台600 MW汽轮发电机组进行现场动平衡试验,介绍了转子动平衡影响系数法、处理多次加重后影响系数的一般性原则和剔除不合理数据的方法.在进行详细的数据分析后发现,有临近转子配重调整时计算所获得的影响系数偏差较大,应予剔除.机组运行工况改变导致的振动数据变化也会造成计算结果存在较大偏差,在计算时应充分考虑.试验结果...

| Abstract: | This article firstly describes influence coefficient method used in rotor dynamic balance.And then how to deal with coefficients acquired from several weight calibrations and test runs and method of how to eliminate unreliable data are discussed in detail with a practical rotor dynamic balance test on a 600 MW generator.Detailed data analyzing shows that coefficients with weights adjusting on neighboring rotor would introduce great deviation,and should be rejected,it also shows that vibration data changing caused by operating mode variations can also introduce great deviation,and should be fully considered.Result of practical test shows that applying this method can improve balance accuracy greatly. |
