摘要
在石油化工生产过程中,为了满足特殊工艺的要求,分程控制系统得到越来越广泛的应用。本文对分程控制系统的工作原理进行了介绍,并对如何采用阀门定位器实现"硬分程",在DCS中通过组态实现"软分程"进行了分析。
In the petroleum chemical industry production process, in order to meet the requirement of special technology, split control system is more and more widely applied, In this papersplit control system working principle were introduced, and how to use the valve control valve to realize＂hard split＂, adopted in the DCS configuration to achieve a＂soft split＇were analyzed.
