氧氮?dú)浞治鰞x的常見故障及解決方法儀器啟動(dòng)時(shí)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(cè)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(cè)器,，用手?jǐn)D壓補(bǔ)水塑料水瓶,，發(fā)現(xiàn)水流正常，顯示正常,，證明水流探測(cè)器正常,，管道暢通。啟動(dòng)循環(huán)水泵,，但分析儀顯示沒有水流，此時(shí)可判定水泵不正常,。打開水泵轉(zhuǎn)子密封口,，啟動(dòng)泵發(fā)現(xiàn)電機(jī)正常運(yùn)轉(zhuǎn)，此時(shí)關(guān)閉進(jìn)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(yùn)行正常,。分析儀,，就選上海禹重實(shí)業(yè)有限公司，用戶的信賴之選,。
