| 摘 要： | 汽轮机大修后在启动过程中的振动故障要仔细分析，避免误判断。对于因为轴封动静碰磨而产生的机组振动，通过在低转速下的磨轴封的措施是可行的，但是必须采用适当的转速，监视机组在启动过程中的振动，防止发生大轴弯曲。

| Abstract: | After overhaul vibration fault of 200MW turbine occurring during the start-up process should be analyzed caref ully to avoid incorrect diagnosis.The vibration caused by the impact wear betwee n the moving and static gland seal could be eliminated by means of abrading the gland seal at lower rotating speed.However,the proper speed and vibration monito ring measures were necessary to prevent the shaft from bending. |
