| 中文摘要: |
| 大型旋转机械如汽轮发电机组，在新机组启动调试或大修后开机运行时，往往会发生动静碰摩故障。文章针对某电厂1号汽轮机组运行中出现的异常振动进行了数据采集与分析，结合该机组实际运行工况，确定故障原因是机组发生了局部动静碰摩。在采取了优化调节阀开启顺序的措施后消除了异常振动，提高了轴系稳定性。 |
| 英文摘要: |
| Static and dynamic rubbing faults often arise when large rotating machinery, such as a steam turbine generator unit, is installed and tested or repaired. The authors of the paper collected and analyzed the data on the abnormal vibration which occurred when the No. 1 steam turbine of a certain power plant worked, and found that it was caused by the local static and dynamic rubbing. The abnormal vibration was eliminated and the stability of the shafting was improved after the optimization of the opening sequence of the regulating valves. |
