描述

在該系統(tǒng)中，每臺泵的需要流量不同，除節(jié)機、一段壓力篩、二段壓力篩、洗節(jié)機、洗渣機、除砂器等整套設備的體積不大，但進出裝置的物料卻很多，傳統(tǒng)情況下，需要由專人看管，隨時調(diào)整漿泵進出口閥門，同時還需兼顧其它設備正常工作的壓力。由于漿泵進口閥門需要關(guān)小，造成漿泵超負荷運行，且磨蝕頻率高，用電負荷大。由于手工操作，造成產(chǎn)品質(zhì)量波動大，從而造成質(zhì)量事故的概率高?，F(xiàn)利用DCS系統(tǒng)，每一物料都需要通過嚴格的PID控制，否則就會造成裝置的堵塞，另外，由于裝置的體積小，慣性小，控制的范圍要求得也小，對控制系統(tǒng)的設計存在一定的難度。如圖2為除節(jié)機的流程圖，從該圖中可以看出，控制該裝置的正常運行，需要5套PID調(diào)節(jié)回路來成功實現(xiàn)對壓力除節(jié)機的控制。
通過DCS系統(tǒng)的操作員站，由于整個系統(tǒng)實現(xiàn)了自控運行，操作人員的主要責任就是監(jiān)控、查詢及發(fā)送相應的指令。通過操作員站及所安裝的監(jiān)控系統(tǒng)，一個人即可完成過去由多人完成的工作，大大提高了效率。
