大型旋转机械状态监测是确保大型生产装置安全、高效运行的重要手段。本文以102-JT转子故障诊断为例,根据故障本身的性质,通过振动分析和对比分析以及对转子机器的全面深入了解和认识,对机器故障的可诊断性积累了经验,进一步完善了故障库。 Large rotating machinery condition monitoring is to ensure that large-scale production safety and efficient operation of an important means. In this paper, 102-JT rotor fault diagnosis is taken as an example. According to the nature of the fault, through vibration analysis and comparative analysis and comprehensive understanding of the rotor machine, we accumulate experience on the diagnostics of the machine fault and further improve the fault library .
