摘要
卧式机组找中心是水轮机检修工作中常见的一项工作。在涉及到定子、轴承座更换时都需要找中心,确定机组轴线,最为基准,方便进行之后的设备安装工作。机组找中心又是一项十分重要和细致的工作,需要把数据控制在±0.02mm,往往需要耗费大量的时间。因此为了在保证测量准确度的情况下提高机组找中心的效率,有效缩短检修工期,采用多种方法分析及处理该问题。
Finding a center for a horizontal unit is a common task in the maintenance of water turbines.When it comes to the replacement of the stator and bearing base,it is necessary to look for the center to determine the axis of the unit,which is the most datum for the convenience of subsequent equipment installation.Locating the center of a unit is an important and detailed work,which needs to control the data at 0.02mm,which often takes a lot of time.Therefore,in order to improve the efficiency of unit center finding and shorten the maintenance period effectively under the condition of ensuring the accuracy of measurement,a variety of methods are used to analyze and deal with this problem.
