新一代可编程控制器LC700在汽油装置上的应用

The Use of New Programming Controller LC700 in Gasoline Equipment

天津大港油田炼达集团溶剂厂汽油装置DCS改造项目以Smar公司用于现场总线系统的新一代可编程控制器LC70 0为主要采集和控制部件 ,完成对现场温度、压力、液位、流量等物理量的精确采集和控制 ,克服过去采用的以仪表为主的测量和控制带来的不精确 ,不灵敏 ,手动操作等弊端 ,实现整个装置测量 (计量 )与控制的完全自动化 ,既保证了产品的质量 。

New programming controller LC700 of SMAR Company is used as main collecting and controlling equipment in gasoline equipment DCS project of Tianjin Dagang oil field Lianda company impregnate factory to accomplish accurately collecting and controlling of temperature,pressure,time,flow.To overcome imprecise,no sensitive and manual operation for eliminating meters,so the measurement and control of the equipment are automatically completely to assure product quality and depress cost.
