摘　　要：空分装置氮产品压缩机在正常运行过程中异常跳车。从机组运行参数、轴承系统静电腐蚀、转子轴向力等方面进行了分析,最终认为,汽轮机侧联轴器膜片安装错误,导致转子轴向力额外增大,造成推力轴承瓦块承载力大幅增大,最终轴瓦巴氏合金损坏,机组联锁跳车。The nitrogen product compressor of the air separation unit trips abnormally during normal operation.This article analyzes the causes of damage to the main thrust bearing pads of the steam turbine from the aspects of unit operating parameters,static corrosion of the bearing system,and axial force of the rotor.The most accurate conclusion is that the installation of the coupling diaphragm on the steam turbine side is incorrect,resulting in an additional increase in axial force of the rotor and a significant increase in the bearing capacity of the thrust bearing pads,The final bearing pad babbitt alloy was damaged,and the unit was interlocked and tripped.
