氧氮?dú)浞治鰞x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(bǔ)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(jī)正常運(yùn)轉(zhuǎn)，此時關(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。浦東新區(qū)LECO分析儀供應(yīng)商
