摘要
Abstract
The layout features of the unit shafting and their effects on shafting vibration and evaluation index were introduced for 1 000 M W ultra supercritical units with Simens technology. Based on the vibration diagnosis and treatment for more than 10 units, some typical vibration faults were summarized, such as the vibration fluctuation of the high pressure (HP) rotor, abnormal vibration increasing of No.3 bearing pedestal and big vibration of the exciter rotor during its critical range of speeds. The vibration characteristics, the causes of faults and countenneasures were analyzed. Three applications were analyzed. The vibration fault identification method, control measures and applications can provide a reference for vibration diagnoses and treatments of the same type units.关键词
