氧氮氢分析仪的常见故障及解决方法供电正常、通讯正常，点击确认键后分析仪不工作。这是没有水流，炉子温度太高或仪器通道电压不正常。如没有水流，炉子温度太高这些信息会显示在显示器画面上，但没有信息显示说明这两项正常。接下来检查仪器通道零位电压，如果比±3V高出1V以上，可能是因为气瓶空了，或者是空气进入到分析仪中。检查并更换化学试剂，如果有空气进入热导池里，热导池的电压就会＜-6V，此时打开右面的门，堵住炉子气体进口，10s后，热导池电压值必然升高。经过逐一排查，**终确认碱石棉有问题，更换后仪器正常。江苏美国LECO分析仪采购分析仪，就选上海禹重实业有限公司，让您满意，欢迎新老客户来电！

氧氮氢分析仪的常见故障及解决方法仪器启动时显示。没有水流。系统分析电流切断，分析停止。这是水流探测器不正常，水泵不工作，管道堵塞。将仪器的右面板取下，观察水流探测器，用手挤压补水塑料水瓶，发现水流正常，显示正常，证明水流探测器正常，管道畅通。启动循环水泵，但分析仪显示没有水流，此时可判定水泵不正常。打开水泵转子密封口，启动泵发现电机正常运转，此时关闭进水，拆下水泵，发现叶轮脱落。经了解，判定是由于外部冷却水停水，仪器内循环水温过高（水温应≤70℃），致使叶轮（叶轮材料PVC）热胀并脱轴。用粘合剂粘合叶轮后再粘于叶轮轴上，待粘合剂凝固后试车，仪器运行正常。分析仪，就选上海禹重实业有限公司，让您满意，欢迎您的来电！广东进口分析仪采购
