3 处理经过及防范措施

六台故障保持原状态阀门，在工艺人员监护下能维持生产，只有64FV15-01阀需要想办法打开。在这紧急情况下，仪表人员凭着多年的仪表维护经验，用信号发生器直接连到64FV15-01阀门定位器上。代替DCS输出信号，按照生产需要加阀位信号，控制阀门开度，维持装置正常生产。待生产装置停车时，对故障AO卡件进行更换，重新调整设置，DCS控制系统恢复正常。图2为生产装置仪表维护人员用信号发生器加阀位信号。

4 经验教训

1）员工责任心强于不强，业务能力高于不高结果是完全不一样的。正是由于值班员能采取有效措施维持生产，为下一步抢修赢得了时间，从而避免了非计划停车。

2）应急反应迅速，要进一步总结经验、举一反三，完善应急预案，加强演练，进一步提高车间应急组织能力。

3）加强典型宣传，加强员工工作责任心教育，加强员工应急响应能力培养，保证装置生产。

4）加强员工操作技能培训，扩大骨干、拔尖技能人才的培养和队伍建设，提高员工发现问题和解决问题能力。
