在天生桥电站安装的一台容量为3000kw的机组时,盘车中发现机组摆度大,按计算绝缘垫最大刮磨量达0.13mm。当时采用的刮磨办法是选用合适重块包砂纸进行人工推磨,尽管推磨中考虑用力均匀,但仍难避免在始末位置有偏重现象。镜板直径800毫米,其厚度仅为45毫米,在推力头与镜板
In Tianshengqiao Power Station installed a capacity of 3000kw units, found in the crankset unit swing, according to the calculation of the maximum amount of insulation pad scraping amounted to 0.13mm. Scraping method used at the time was selected by the appropriate weight of sandpaper for manual grinding, even though the push into the uniform force, but still difficult to avoid in the end position of the phenomenon of bias. Mirror plate diameter of 800 mm, its thickness is only 45 mm, the thrust head and mirror plate
