摘　　要：某电厂1号汽轮发电机组自投产后发电机轴承座振动偏大,且处于爬升状态。通过现场详细、全面的测试,诊断其故障原因在于发电机台板和基础间可能存在脱空,利用检修机会对发电机进行了一次现场动平衡工作,使发电机轴承座振动得到了一定改善。最后,给出了进一步改善发电机轴承座振动的具体措施。The generator bearing housing vibration of one power plant No. I unit has been exceeded standard since put into operation and has been in state of gradually climbing. Through exhaustive and comprehensive field test, diagnosing the feasible cause of the malfunction is that there is interval between the generator platen and the base, and then implementing once field dynamic balancing during the overhaul. The generator bearing housing vibration has been certainly improvement. Finally, the further specific measurement has been given, which is used to improve the generator bearing housing vibration.
