离心压缩机组冷态找正数据的分析与精确计算

Analysis and Accurate Calculation of Cold Alignment Data for Centrifugal Compressor Unit

针对在安装引进的离心压缩机组中发现的原机组冷态找正数据与实测值不符的情况，介绍了其试验的方法，并提出了一种行之有效的精确计算方法。用该方法计算了该压缩机组的冷态找正数据，并与实测数据作了比较。从而证明该计算方法的可行性及正确性。

Against the situation that the cold alignment data doesn't meet the actual measured value of primary unit mounted in the imported centrifugal compressor unit. its test method is introduced and accurate calculating method is raised. Cold alignment data for the compressor unit is calculated by this method, and compaired with practically measured data, thus, practicability and correctness Of this calculating method are proved.
