大型同步电机主轴弯曲的火焰矫正

Flame-rectifying Technique for the Bending of the Main Shaft of Large Synchronous Motor

在泗阳第二抽水站主机泵的安装过程中出现电机主轴弯曲、摆度严重超标等问题,经过多次反复的烘烤、冷却、锤击,顺利地解决了上述问题。本文介绍了操作方法,分析了矫正的原理。

The flame-rectifying technique is designed to solve the problem as to the bending of the main shaft and large cone-degree. The problem has been settled successfully by repeated baking, cooling and hammering. This paper describes the rectifying method and analyses its principle.
