氧氮氫分析儀的常見故障及解決方法儀器啟動時顯示,。沒有水流,。系統(tǒng)分析電流切斷,,分析停止,。這是水流探測器不正常,水泵不工作,,管道堵塞,。將儀器的右面板取下,,觀察水流探測器,,用手?jǐn)D壓補水塑料水瓶,,發(fā)現(xiàn)水流正常,,顯示正常,,證明水流探測器正常,,管道暢通,。啟動循環(huán)水泵,,但分析儀顯示沒有水流,,此時可判定水泵不正常。打開水泵轉(zhuǎn)子密封口,,啟動泵發(fā)現(xiàn)電機正常運轉(zhuǎn),,此時關(guān)閉進水,,拆下水泵,,發(fā)現(xiàn)葉輪脫落,。經(jīng)了解,,判定是由于外部冷卻水停水,,儀器內(nèi)循環(huán)水溫過高(水溫應(yīng)≤70℃),,致使葉輪(葉輪材料PVC)熱脹并脫軸,。用粘合劑粘合葉輪后再粘于葉輪軸上,,待粘合劑凝固后試車,,儀器運行正常。上海禹重實業(yè)有限公司為您提供分析儀,,期待您的光臨,!廣東氧氮氫分析儀

氧氮氫分析儀的常見故障及解決方法供電正常,、通訊正常,點擊確認(rèn)鍵后分析儀不工作,。這是沒有水流,,爐子溫度太高或儀器通道電壓不正常,。如沒有水流,,爐子溫度太高這些信息會顯示在顯示器畫面上,,但沒有信息顯示說明這兩項正常,。接下來檢查儀器通道零位電壓,,如果比±3V高出1V以上,,可能是因為氣瓶空了,,或者是空氣進入到分析儀中,。檢查并更換化學(xué)試劑,如果有空氣進入熱導(dǎo)池里,,熱導(dǎo)池的電壓就會<-6V,,此時打開右面的門,堵住爐子氣體進口,,10s后,,熱導(dǎo)池電壓值必然升高。經(jīng)過逐一排查,,**終確認(rèn)堿石棉有問題,,更換后儀器正常。山西氧氮氫分析儀哪家好
