摘要
某350 MW超临界汽轮机启动及带负荷过程中出现汽轮机挂闸后转速上升、转速1000转6瓦振动大、转速2000转4瓦温度高温差大、机组真空低保护跳闸等一系列问题。经分析处理均得到妥善解决。
While a 350MW supercritical turbine started and loaded,the turbine switched on and rise of the rotating speed;the six bush vibrated when the rotating speed reached 1000rpm,the four bush's temperature and the differential temperature were high when the rotating speed reached 2000rpm,the turbine vacuum was low,the safeguard tripped.The article analyzed the reasons,the problem was solved and it's worthy of reference by the other of same turbine unit.
