随着设备状态监测及诊断技术的推广应用,在单机设备上突破传统的定期计划预检修方式,即采用状态监测维修(预知维修)不仅成为可能,而且正变为现实。但对石油化工等流程工业来讲,一个生产装置、一条生产线运行一定周期后,往往要同步停车大检修;即使大部分设备延长了检修周期,并不一定能延长石化企业整个生产线设备的运转时间,因此经济效益不很显著。本文拟在总结应用振动分析法对大型机组监测诊断,延长运行周期的实践基础上,探讨石化企业维修决策的特殊性,如何应用监测诊断技术“预知”石油化工生产线中哪
With the popularization and application of equipment condition monitoring and diagnosis technology, it is not only possible but also becoming a reality to break through the traditional scheduled plan pre-inspection mode on stand-alone equipment, that is, using condition monitoring and maintenance (predictive maintenance). However, in the case of the petrochemical industry and other process industries, a production plant and a production line often require frequent overhaul after a certain period of operation. Even if most of the equipment is extended overhaul intervals, it may not be able to extend the operation time of the entire production line of petrochemical plants , So the economic benefits are not significant. This paper intends to summarize the application of vibration analysis of large unit monitoring and diagnosis, to extend the operational cycle based on the practice of petrochemical enterprises to explore the specificity of decision-making maintenance, how to use monitoring and diagnosis technology, “predict” which petrochemical production line
