摘要
针对发电机组轴向振动产生的原因进行了分析和检测,发现了内冷水导管堵塞引起的转子局部热变形是造成轴向振动过大的原因。根据分析和检测的结果,采取了相应的消除措施,有效降低了机组系统的轴向振动。
After analyzing and testing, the reasons of axial vibration of generator set were found out: the thermal deformation occurred in a local part of the rotor due to the blockage in the internal cooling water tube caused the abnormal axial vibration. According to the results of the analysis and testing, relevant countermeasures were adopted and the axial vibration of the generator set was reduced effectively.
