摘要
介绍了美国GE公司生产的大型9FA燃气机组冷态启动时的振动爬升问题,即热瞬变振动现象。针对热瞬变振动现象,分析了其产生的机理,并采用有效方法解决了振动问题,可供同类型机组参考。
The unstable vibration problem which is called thermal transient vibration behavior in cold starting occurred in the heavy-duty 9FA gas turbine is introduced. The principle of the unstable vibration is analyzed and corrected by effective method, which offers a reference for other units of the same type.
