摘要
针对某公司由于离心压缩机组本特利3500轴位移及轴振动信号受干扰,造成离心压缩机组停车;西门子PCS7-400DCS控制系统重要模拟量信号受干扰,造成净化和合成工段非正常停车两起事件,分析了西门子PCS7-400DCS系统干扰信号产生的原因,提出了离心机组3500轴振动位移监测系统与西门子PCS7-400DCS控制系统信号稳定运行的对策并予以实施。
For a company due to the centrifugal compressor unit Bentley 3500 axis displacement and shaft vibration signals were disturbed, causing the centrifugal compressor unit to stop;Siemens PCS7-400 DCS control system important analog signals were disturbed, resulting in two events in the purification and synthesis section abnormal shutdown The reasons for the interference signal of Siemens PCS7-400 DCS system were analyzed, and the countermeasures for the stable operation of the signal of the centrifugal unit 3500 axis vibration displacement monitoring system and Siemens PCS7-400 DCS control system were put forward and implemented.
