摘　　要：结合实例,分析了国产引进型600MW机组低发对轮中心状况变化的影响因素,以及低发对轮中心状况变化对机组轴系振动的影响,工程实践证明,对轮中心状况的变化是导致国产引进型600MW机组低压转子和发电机转子轴系振动不稳定的重要原因之一,对同类型机组的中心调整有一定的参考意义。In this paper, influence factors of center conditions of low-fat on the wheel of 600MW turbine generator were analyzed, as well as influence of center conditions of low-fat on the wheel on shaft vibration. Engineering practice shows that the change of the wheel center is one of the important reasons of vibration instability of domestic imported 600MW unit low pressure rotor and the generator rotor shaft. The paper has some reference value for center adjustment of the similar generator.
