水轮发电机组轴线常通过盘车方法使机组转子转动,以检查轴线的曲折情况。各机件制作上的误差有:推力头与轴的垂直误差;镜板、卡环的平行误差;发电机和水轮机轴法兰盘倾斜误差;大轴的弯曲和在推力头与镜板所加的绝缘垫厚度误差;以及安装
Turbine generator axis often through the crank method to rotate the unit rotor to check the twists and turns of the axis. The error of the production of the parts are: thrust head and shaft vertical error; mirror plate, clasp parallel to the error; generator and turbine shaft flange tilt error; large axis bending and the thrust head and mirror plate plus Insulation pad thickness error; and installation
