PLC在化浆蒸煮系统中的应用

Application of the PLC in the Paper Making Control System

本文介绍了化浆蒸煮过程控制系统的组成以及ＧＥ系列可编程控制器在控制系统中的应用

In This paper, a computer control system designed for raw material boiling and paper making process is introduced. Moreover, GE series programmable logic controllers applied in this system is discussed. Keyword: raw material boiling process;total distributed system;control tabled removing stasis. Hepatic CCO activity and serous GPT content were chosen as criteria in the study. The rats were divided into four groups, namely control, model, preventing and treating. The results showed that drugs for promoting blood circulation and removing stasis had comparatively marked hepatic fibrosis fighting effects, especially, the hepatic fibrosis preventing effect.
