竖轴水轮发电机,以盘车方式测量其大轴各部的净摆度值,实质是测量大轴与镜板摩擦面的垂直误差。这个误差若是太大,必给水轮发电机的运行带来种种不利。因此,测量、计算和处理大轴的摆度,对于竖轴水轮发电机的安装和检修,是项很重要的工作。测量大轴摆度的方法和计算大轴摆度的公式,早已成为定论。但是,随着水轮发电机的日趋大型化,其推力轴承与上导轴承之 Vertical axis hydroelectric generator, with the pan method to measure the net value of the various parts of the major axis of the swing value, the essence is to measure the vertical axis and mirror plate friction surface vertical error. If this error is too large, it will bring various disadvantages to the operation of the hydroelectric generator. Therefore, measuring, calculating and handling the swing of a large shaft is a very important task for the installation and maintenance of a vertical shaft hydroelectric generator. The method of measuring large-axis yaw and the formula for calculating the large-axis swing have long been the subject of conclusion. However, with the increasing size of hydroelectric generators, the thrust bearing and the upper guide bearing thereof
