汽轮发电机组轴系调整对轮中心的快速计算方法

Fast algorithm for aligning couplings of steam turbo unit shafting

针对具有多轴、多支承特点的现代大型电厂的汽轮发电机组大修时， 轴系对轮找中心计算的复杂性及紧迫性， 利用Ｍｉｃｒｏｓｏｆｔ Ｅｘｃｅｌ 的函数运算功能， 以表格形式编制“汽轮发电机组轴系对轮找中心快速计算方法软件”， 这个软件能综合考虑多个对轮调整时的相互影响， 能根据各对轮中心的初始偏差及计算人所设定的偏差要求值快速计算并决定一个既适合现场实际， 又能符合设计偏差要求的对轮中心调整方案。

In view of the complicacy and urgency of aligning calculation of shaft couplings during overhaul of modern steam turbines,a software for such calculation is developed based on Microsoft Excel.Comprehensively considering the interaction of couplings under regulation,the software can,according to the initial central deviation of each coupling and the deviation demands,fast work out a coupling aligning plan which not only suits the practical situation on site but also meets the designed deviation demands.
