描述

IC697CMM711

隨著自動(dòng)化水平的提高，DCS控制系統(tǒng)(集散控制系統(tǒng))逐漸代替了常規(guī)儀表，其優(yōu)越性已被廣大操作人員所接受。但發(fā)生故障時(shí)，會(huì)造成裝置停車甚至事故，各種故障如何及早發(fā)現(xiàn)及恰當(dāng)處理就顯得非常重要。我公司合成氨工藝使用多套浙大中控JX-300DCS進(jìn)行控制，控制穩(wěn)定可靠，針對(duì)存在的一些問題，根據(jù)多年維護(hù)經(jīng)驗(yàn)，我們總結(jié)出了一套行之有效的故障判別及處理方法。
? ? 1、查看監(jiān)控畫面的數(shù)據(jù)
? ? 出現(xiàn)以下情況時(shí)，說明控制系統(tǒng)發(fā)生問題，應(yīng)立即通知微機(jī)維修人員維修，同時(shí)操作工到現(xiàn)場(chǎng)進(jìn)行處理。
? ? (1)經(jīng)常變化的數(shù)據(jù)長(zhǎng)時(shí)間不變，且?guī)讉€(gè)數(shù)據(jù)或所有數(shù)據(jù)都不變。
? ? (2)控制分組畫面中，手動(dòng)自動(dòng)無法切換，或手動(dòng)輸入數(shù)據(jù)后，一經(jīng)確認(rèn)，又恢復(fù)為原來的數(shù)據(jù)，修改不過來。
? ? (3)趨勢(shì)圖畫面中，幾條趨勢(shì)都為直線不變。
? ? (4)監(jiān)控畫面中，多個(gè)數(shù)據(jù)同時(shí)波動(dòng)較大。
? ? 判斷波動(dòng)數(shù)據(jù)是否為工藝上相關(guān)參數(shù)，若是相關(guān)參數(shù)則通知儀表及微機(jī)人員檢查，看是否某調(diào)節(jié)系統(tǒng)波動(dòng)引起相關(guān)參數(shù)變化，同時(shí)將相關(guān)調(diào)節(jié)系統(tǒng)打到手動(dòng)狀態(tài)，必要時(shí)到現(xiàn)場(chǎng)進(jìn)行調(diào)節(jié)。如水溶液全循環(huán)裝置中，尿素合成塔壓力正常時(shí)為l9．67MPa，如果突然大范圍波動(dòng)，此時(shí)勢(shì)必引起下游的中壓系統(tǒng)、低壓系統(tǒng)壓力波動(dòng)，這種情況是由于幾個(gè)相關(guān)參數(shù)中某一參數(shù)波動(dòng)引起其他參數(shù)變化，并不是控制系統(tǒng)本身故障。
? ? 若波動(dòng)數(shù)據(jù)工藝上彼此并無直接影響，則可能為微機(jī)某卡件發(fā)生故障，立即將相關(guān)自調(diào)系統(tǒng)打到手動(dòng)調(diào)節(jié)，必要時(shí)到現(xiàn)場(chǎng)進(jìn)行調(diào)節(jié)，同時(shí)，通知微機(jī)及儀表人員檢查。

選擇深圳長(zhǎng)欣，選擇放心，售后無憂大量現(xiàn)貨，當(dāng)天順豐發(fā)貨！
主營(yíng)：本特利，英維思，伍德沃德，?？怂共_、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂，ACSO，力士樂等各大品牌的DCS系統(tǒng)配件，機(jī)器人系統(tǒng)配件，大型伺服系統(tǒng)備件。

先介紹幾點(diǎn)經(jīng)驗(yàn)。
1、先通讀一遍“系統(tǒng)手冊(cè)”（不管能不能看懂，先了解個(gè)大概，以便學(xué)習(xí)編程時(shí)查找）；
2、由位控邏輯入手，逐漸增加定時(shí)、計(jì)數(shù)等條件，把或、與、非關(guān)系理順；
3、進(jìn)而練習(xí)整數(shù)運(yùn)算、實(shí)數(shù)運(yùn)算、類型轉(zhuǎn)換；
4、量程轉(zhuǎn)換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解（最好是有個(gè)物理回路驗(yàn)證，比如變頻器+電機(jī)+測(cè)速傳感器）；
5、循環(huán)、順序、跳轉(zhuǎn)等程序控制（盡量避免跳轉(zhuǎn)，非跳不可時(shí)也是跳的越近越好）；
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機(jī)器人配件DSQC系列和Motorola MVME系列，GE 卡件 模塊 驅(qū)動(dòng)器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌，由于PLC的基本框架大同小異，學(xué)會(huì)一種至于其它的學(xué)習(xí)起來也就簡(jiǎn)單了。
