摘要
以某汽油脱硫装置闭锁料斗单元的31台程控球阀为例,开展以可靠性为中心的维修(RCM)分析.通过故障模式与影响分析,识别程控球阀的主要失效模式,分析失效原因,确定故障的影响及其风险等级,并给出合适的故障识别方法,提出合理的维修时间和维修类型,改善了程控球阀运行状况,降低故障率.优化后的方案提升了程控球阀的运行可靠性,减少了闭锁料斗单元非计划停运次数.
Abstract
Taking 31 programmable ball valves in the locking hopper unit of a certain gasoline desulfurization unit as an example,a reliability centered maintenance(RCM)analysis is conducted.Through fault mode and impact analysis,the main failure modes of programmable ball valves are identified,the causes of failure are analyzed,the impact and risk level of faults are determined,and appropriate fault identification methods are provided,reasonable maintenance time and types are proposed.The operating condition of programmable ball valves is improved,the failure rate is reduced.The optimized strategy has improved the operational reliability of the programmable ball valve and reduced unplanned shutdowns of the locking hopper unit.
