氧氮氫分析儀的常見故障及解決方法：氧和氮空白值超過20。這是由于氣流小，不能將爐子中的空氣驅(qū)趕出去?？烧{(diào)節(jié)氣體流量，調(diào)節(jié)載氣壓力在0.2~0.4MPa。接通儀器載氣，放一個石墨坩堝在下電極上，打開主電源開關(guān)，點擊軟件上的關(guān)爐按鈕，關(guān)閉爐子并等待10s。調(diào)節(jié)流量調(diào)節(jié)器，直到流量計a顯示為30L／h，打開爐子。調(diào)節(jié)調(diào)節(jié)器直到流量計b顯示為50L／h，再次關(guān)閉爐子。如果以上設(shè)置不穩(wěn)定，則增加流量至100L／h，反復(fù)調(diào)節(jié)直至儀器穩(wěn)定。試樣加載過程中完全密閉，消除大氣的中可能帶來的雜質(zhì)的污染。專業(yè)元素分析儀

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(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，儀器運行正常。
