悬式水轮发电机组盘车检查轴线时,如果回转磨擦面支承是刚性的,磨擦面也是刚性的,盘车时转动部分又不受不平衡径向力的干扰,则转动一圈所测数值应完全符合正弦曲线规律,x、y方位两只表所测摆度值的大小、方向也应一致。当盘车两圈后所测四组数据的大小、方向均应一致。在实际工作中,常出现盘车摆度值不成 Suspension hydro-generator set crankshaft inspection axis, if the rotary friction surface support is rigid, the friction surface is also rigid, turning when turning the wheel unbalanced radial force interference, the measured value of a revolution Should be fully consistent with the law of sinusoidal, x, y azimuth two tables measured value of the size of the swing, the direction should be the same. When the car lap measured after two sets of data size, direction should be the same. In actual work, it often happens that the value of the drive can not be adjusted
