摘　　要：通过对部分石化企业近4年安全仪表系统相关的非计划停工情况统计分析,发现传感器、执行器设置不当是安全仪表系统误动作引起装置非计划停工的主要因素,提出了一种基于风险的降低安全仪表系统误动作的方法,应用表明,能够有效降低泵非计划停工,减少经济损失。Through statistical analysis on non-planned shutdown related to safety instrument system of the some petrochemical enterprises in recent 4 years, it is found that the improper setting of sensor and actuator is the main factor causing non-planned shutdown of the device due to the malfunction of the safety instrument system. As a result, a risk-based method for reducing the malfunction of safety instrument system is proposed. The application indicates that the non-planned shutdown of the pump could be reduced effectively and the economic losses also could be mitigated.
