Siemens RLU222現(xiàn)貨 in stock! 歡迎來電咨詢~??！

　　燕山石化公司合成橡膠凝聚裝置的儀表控制系統(tǒng)原由常規(guī)儀表構(gòu)成，且全是其他裝置更換下來的舊表，故障率較高。為了提高自動化水平，增強儀表控制系統(tǒng)的可靠性，我們對其進行了改造，淘汰了控制室內(nèi)的所有常規(guī)儀表，改用DCS。
　浙大中控公司的SUPCON JX-300X DCS充分利用了最新信號處理技術(shù)、高速網(wǎng)絡(luò)通信技術(shù)、可靠成熟的先進控制算法，使其兼具了高速可靠的數(shù)據(jù)輸入輸出運算、過程控制和PLC聯(lián)鎖邏輯控制功能，獲得了廣泛的應(yīng)用，特別是其性能價格比優(yōu)于同等規(guī)模的常規(guī)儀表系統(tǒng)，成了我們儀表改造首選的產(chǎn)品。
　　二 工藝流程簡介
　　凝聚裝置采用水蒸氣蒸餾、濕法脫氣的原理，脫去膠液中的溶劑油。現(xiàn)有兩條生產(chǎn)線，每條線包括膠罐系統(tǒng)、凝聚釜系統(tǒng)、尾氣回收系統(tǒng)。每條生產(chǎn)線有4個膠罐，根據(jù)膠液熔融指數(shù)的不同，不同膠罐中的膠液按相應(yīng)的比例混配，保證膠液熔融指數(shù)合格。合格的膠液送至凝聚釜，根據(jù)水蒸氣蒸餾、濕法脫氣的原理，采用等壓不等溫的雙釜水析凝聚技術(shù)，把溶劑油和膠分離。凝聚釜分離出來的溶劑油尾氣由尾氣回收系統(tǒng)回收再利用。
　　三 DCS配置
　　JX-300X DCS由一個多功能站、一個操作站、一個控制站和過程控制網(wǎng)絡(luò)組成，系統(tǒng)結(jié)構(gòu)如圖1。
護工具。操作站是操作人員完成生產(chǎn)過程監(jiān)控管理任務(wù)的平臺。
　　多功能站和操作站的硬件組成是完全一樣的，包括工控PC機、CRT、鼠標、鍵盤、網(wǎng)卡、專用操作員鍵盤、操作臺等。
　　控制站完成整個工業(yè)過程的實時監(jiān)控功能，由主控制卡、數(shù)據(jù)轉(zhuǎn)發(fā)卡、I/O卡件、供電單元等組成。控制站的各種卡件均可冗余配置，為了增加系統(tǒng)的可靠性，我們對控制站的主控制卡、數(shù)據(jù)轉(zhuǎn)發(fā)卡進行了冗余配置，控制回路的I/O卡件也采用冗余配置。表1列出了控制站的硬件，表2為系統(tǒng)的I/O信號及卡件配備表。
