摘　　要：顶轴油系统是汽轮机润滑油系统中的重要子系统,在汽轮机启停过程中起着减小盘车力矩、保护汽轮机转子和轴瓦的重要作用。基于电厂330 MW汽轮机顶轴油系统调试中母管压力低问题,阐述了汽轮机顶轴油系统概况,分析了顶轴油母管压力低故障的原因和处理过程,以期为其他顶轴油系统故障处理提供借鉴。The jacking oil system is an important subsystem of steam turbine lubricating oil system,which plays an role in jacking rotor,reducing turning moment,protecting rotor and bearing bush during the process of turbine starting and stopping.Based on the low pressure of the parent pipe in the test of the jacking oil system of the 330 MW turbine in some power plant,the jacking oil system of steam turbine is described.The cause and treatment process of the low pressure of the jacking oil master pipe is analyzed,which hopes to provide theoretical reference for the other faults of the jacking oil system.
