根據多年維護經驗,我們總結出了一套行之有效的故障判別及處理方法。
1、查看監控畫面的數據
出現以下情況時,說明控制系統發生問題,應立即通知微機維修人員維修,同時操作工到現場進行處理。
(1) 經常變化的數據長時間不變,且幾個數據或所有數據都不變。
(2) 控制分組畫面中,手動自動無法切換,或手動輸入數據后,一經確認,又恢復為原來的數據,修改不過來。
(3) 趨勢圖畫面中,幾條趨勢都為直線不變。
(4) 監控畫面中,多個數據同時波動較大。

判斷波動數據是否為工藝上相關參數,若是相關參數則通知儀表及微機人員檢查,看是否某調節系統波動引起相關參數變化,同時將相關調節系統打到手動狀態,必要時到現場進行調節。如水溶液全循環裝置中,尿素合成塔壓力正常時為l9.67MPa,如果突然大范圍波動,此時勢必引起下游的中壓系統、低壓系統壓力波動,這種情況是由于幾個相關參數中某一參數波動引起其他參數變化,并不是控制系統本身故障。
若波動數據工藝上彼此并無直接影響,則可能為微機某卡件發生故障,立即將相關自調系統打到手動調節,必要時到現場進行調節,同時,通知微機及儀表人員檢查。
當發現多個自調系統失靈,監控畫面上自調閥閥位在全開或全關位置,立即檢查儀表氣源壓力,若氣源壓力小于0.4MPa,則不正常,檢查氣源管道有無堵塞或漏氣現象;若氣源壓力小于0.2MPa,立即進行緊急停車。將監控畫面上的自調系統全部打到手動,將調節閥閥位調到安全位置,通知儀表工檢查氣源,同時到現場進行操作,關閉調節閥兩端的截止閥,用旁路閥操作。
