01.DCS日常维护

DCS维护无论就化工厂、钢厂、冶金厂、电厂等等生产企业来说都有那么几分神秘无论DCS出多么微小或多么紧急的事情都只能等那么几个人到了才能动、才能处理。

在仪表维护人心里DCS维护是个高大上的神圣职业，那么DCS日常维护包括哪些内容呢？

DCS 的维护可分为：日常维护;预防性维护和故障维护，日常维护和预防维护是在系统未发生故障所进行的维护。故障维护发生在故障产生之后,往往 已造成系统部分功能失灵并对生产造成不良影响;相反,预防性维护是在系统正常运行时,对系统进行有计划的定期维护,及时掌握系统运行状态、消除系统故障隐 患、保证系统长期稳定可靠地运行,形成定期维护的概念。实践证明,定期维护能够有效地防止DCS 突发故障的产生,形成可观的间接经济效益。

DCS 系统的日常维护

系统的日常维护是DCS系统稳定高效运行的基础，主要的维护工作有以下几点：

1） 完善DCS系统管理制度。

2） 保证空调设备稳定运行,保证室温变化小于±5℃/h ,避免由于温度、湿度急剧变化导致在系统设备上的凝露。

3） 尽量避免电磁场对系统的干扰,避免移动运行中的操作站、显示器等,避免拉动或碰伤设备连接电缆和通讯电缆等。

4） 注意防尘，现场与控制室合理隔离，并定时清扫，保持清洁，防止粉尘对元件运行及散热产生不良影响;

5） 严禁使用非正版软件和安装与系统无关软件。

6） 做好控制子目录文件的备份,各自控回路的PID 参数、调节器正反作用等系统数据记录工作。

7） 检查控制主机、显示器、鼠标、键盘等硬件是否完好,实时监控工作是否正常。

8） 查看故障诊断画面,是否有故障提示。
