摘　　要：台山电厂600MW汽轮机6瓦多次出现瓦温过高异常,危及汽轮机安全运行,降低了机组可靠性。通过技术人员分析,认为造成瓦温高的原因有轴系稳定性、轴瓦自位能力和轴颈表面损伤等原因,随后对6瓦的检修工艺进行了针对性改进,形成了一套较为可行的检修措施,从而使6瓦检修后的可靠性提高。For the exceptional high temperature of No.6 bearing pad of the 600MW unit in Taishan Power Generation Company Ltd.,it has been concluded that the reasons attribute to shafting system stability,bearing pad self-aligning ability and journal impairment etc.Then,correspondingly improvment for No.6 bearing pad maintenance process has been done,and feasible maintenance measures taken for increasing reliability of No.6 bearing.
