摘要
为解决1号轴承瓦温偏高问题,通过调整轴系的负荷分配,使推力盘平行度误差增大,造成推力瓦块磨损故障,推力瓦块每运行6个月即报废。通过恢复轴系设计参数,使问题得以解决,故障原因分析及处理过程可为同类型机组提供参考。
For imported 350 MW turbine engine thrust pad wear fault,through analysis and the disintegration of the diagnosis results.In order to solve the No. 1 bearing pad temperature,shaft load distribution caused by thrust disk parallelism error increase is adjusted.The problem can be solved by restoring the shaft design parameters. The cause analysis and treatment is a reference for the same type of unit.
