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趕出去??烧{節(jié)氣體流量,調節(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,點擊軟件上的關爐按鈕,關閉爐子并等待10s。調節(jié)流量調節(jié)器,直到流量計a顯示為30L/h,打開爐子。調節(jié)調節(jié)器直到流量計b顯示為50L/h,再次關閉爐子。如果以上設置不穩(wěn)定,則增加流量至100L/h,反復調節(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,用手擠壓補水塑料水瓶,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。打開水泵轉子密封口,啟動泵發(fā)現(xiàn)電機正常運轉,此時關閉進水,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≤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。
