氧氮?dú)浞治鰞x的常見故障及解決方法：氧和氮空白值超過(guò)20,。這是由于氣流小,，不能將爐子中的空氣驅(qū)趕出去。可調(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(gè)石墨坩堝在下電極上,，打開主電源開關(guān)，點(diǎn)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(jì)a顯示為30L／h,，打開爐子,。調(diào)節(jié)調(diào)節(jié)器直到流量計(jì)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(guò)程中完全密閉,，消除大氣的中可能帶來(lái)的雜質(zhì)的污染。專業(yè)元素分析儀

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(méi)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(méi)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(guò)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,。
