摘　　要：文章对某电厂6台汽轮机"交流润滑油泵与备用泵切换时油压过低致使机组跳机"的共性故障进行分析,通过特定实验排查和解决问题,并总结故障要点,为汽机厂设计优化及电厂汽机调试提供了重要参考.In this paper, the common problem of six steam turbines in a power plant are analyzed, when the AC lubricating oil pump is switched to the spare pump, the oil pressure is to low to causes the turbine to jump, and the common faults are invistgated and solved through the special experiments, which provides important reference for the design optimization of the turbine plants and the commissioning of the power plants.
