摘要: 基于以可靠性为中心的维护(RCM)方法,以往复式酸气压缩机的结构信息、监检测数据及运行历史故障记录为依据,开展关键部件故障模式及风险等级评估,并根据评估结果提出维修策略,以减少故障频次,降低维修成本。针对气阀损坏、接头脱落和硫化氢泄漏等主要故障问题,从经济、环境、安全和维修维护四个维度确定风险等级,其中密封垫片、排气阀和吸气阀故障被评定为中等风险,建议采用定期更换的维修策略;其余部件均为低风险,推荐采用定期维护与振动状态监测相结合的运行策略。同时,基于风险降低原则和逻辑决断方法,制定出相应的检查和维护策略。该评估方法可对压缩机的经济性、环保性、安全性与可维护性进行综合权衡,实现整体性能最优,为构建经济高效的维修策略提供重要参考。

Abstract: Based on the Reliability-Centered Maintenance (RCM) methodology, fault mode analysis and risk level evaluation of key components are carried out on the basis of structural information, monitoring data and historical fault records of reciprocating acid gas compressors. Maintenance strategies are proposed in accordance with the assessment results to reduce failure frequency and cut maintenance costs. For major failures such as valve damage, joint detachment and hydrogen sulfide leakage, risk levels are determined from four dimensions covering economy, environment, safety and maintenance. Among these, failures of the sealing gaskets, discharge valves and suction valves are rated as medium risk, for which a periodic replacement maintenance strategy is recommended. All other components are classified as low risk, and an operational strategy combining routine maintenance with vibration condition monitoring is proposed. Meanwhile, corresponding inspection and maintenance strategies are formulated based on the risk reduction principle and logical decision analysis method. This assessment method enables a comprehensive trade-off among the compressor's economic performance, environmental protection, safety level and maintainability, thereby achieving optimal overall performance. It provides an important reference for developing cost-effective maintenance strategies.
