摘要
通过几起东方汽轮机厂生产的亚临界参数300 MW、600 MW汽轮机低频振动故障实例,分析了高中压转子振动特性及稳定性问题,提出了运行、检修和设计中防范低频振动应注意的问题和措施。
Based on several low-frequency vibration faults occurred in subcritical turbine of 300 MW and 600 MW which is made by Dong Fang Steam Turbine Works,this paper analyzes the vibration characteristics and stability problem of HP ＆amp; IP rotor,then puts forward the cautions and some measures to prevent the low-frequency vibration in operation,overhaul and design.
