某超临界600MW汽轮机汽流激振故障分析与处理
摘要
某超临界600MW汽轮机组存在1、2号轴振波动故障
对其进行了试验诊断
查明机组振动故障原因是由于调节阀开启顺序设计不合理所致。采取改变调节阀开启顺序的措施后
振动故障得以消除。
Abstract
Directing against the vibration fluctuating trouble existing on shafts no.1 and no.2 of one supercritical 600 MW steam turbine unit
test and diagnosis have been carried out.It is found out that the cause of said vibration trouble on said unit was due to unreasonable designed open sequence of the govenor valve.After adopting measures for improving the open sequence of said govenor valve
