摘要
介绍了汽轮发电机组汽流激振产生的机理、振动特征及处理措施,最后结合一台300MW机组高中压转子低频振动实例对汽流激振的处理过程进行了详细的论述,并对消振工作进行了总结,为今后类似问题的处理提供依据和帮助。
This essay presents the mechanism,features and dealing of steam-induced vibration of turbo-unit,and then describes the dealing process of steam-induced vibration.By combining with a case of HP-IP rotor's low-frequency vibration of one 300MW unit,it comes to a conclusion on the work done for damping,which is useful for further dealing of the similar fault.
