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，發現水流正常，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，啟動泵發現電機正常運轉，此時關閉進水，拆下水泵，發現葉輪脫落。經了解，判定是由于外部冷卻水停水，儀器內循環水溫過高（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。分析儀，就選上海禹重實業有限公司，用戶的信賴之選。
