机组盘车是水轮发电机组安装非常重要的、非常关键的一个工序。通过对盘车数据的整理及分析,能确定盘车数据是否真实可用,及时发现盘车过程中的错误;根据盘车数据的计算结果,为机组轴线调整、机组找中心、导轴瓦调整瓦隙的分配提供了依据。通过应用最小二乘法对盘车数据进行分析,可以最接近的得到盘车测量点对应的旋转部件典型部位的轴心偏离机组旋转中心的大小和方位。依据计算结果对轴线调整的方位和大小、导轴瓦瓦隙计算与调整提供了依据。
Unit crank is a very important and crucial part of turbine generator installation. According to the calculation results of the data of the carriages, it can be used to adjust the axis of the unit, find the center of the unit, and adjust the width of the guide bush to make sure that the data of the carriages is real and available. Provided a basis for the allocation. By using the least squares method to analyze the data of the turning car, the axis of the typical part of the rotating part corresponding to the measuring point of the turning car can be closest to the size and orientation of the rotation center of the generating set. According to the results of calculation, the orientation and size of the axis adjustment and the calculation and adjustment of the guide bush’s backlash are provided.
