摘　　要：介绍过去几年对某汽轮机、发电机、凝结水泵驱动电机和脱硫增压风机振动问题处理过程的案例分析,说明振动故障诊断和治理技术的实际应用及效果。这些故障涉及轴承失效、发电机动态匝间短路、结构共振和不稳定质量不平衡。每个案例分析中均给出诊断结论的评述以供参考。In this paper, the case analysis on the vibration problems and their trouble-shooting for some steam turbines, geuerators, the driving motor of condensate water pumps and raw gas booster fans conducted in the past few years are presented. The analysis illuslrates the actual application and effects of vibration fault diagnosis and control techniques. These faults involve bearing failure, gcnerator dynamic inter-turn short eireuit, structure resonance and unstable mass unbalance. In each ease, the comments on the conclusion of diagnosis are put forward for referenee.
