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。 安徽元素分析仪哪家好减少了繁琐的额外数据处理。

Sample Preparation

Sampling and sample preparation is an important issue because traditional methods used to obtain samples for oxygen and nitrogen determination are different from those recommended for hydrogen, especially when sampling molten metal. The main difference in steel sampling procedures for oxygen/nitrogen and hydrogen is due to the mobilityof hydrogen. Special precautions must be used when sampling for hydrogen. From molten steel and iron, a sample must be quickly quenched in cold water and chilled in a refrigerant such as liquefied nitrogen or a mixture of acetone and solid carbon dioxide in order to reduce losses of hydrogen from diffusion. Losses of oxygen and nitrogen from diffusion are not a problem. A sample that is taken for hydrogen and

chilled in a refrigerant can also be used for oxygen and nitrogen determination. However, a sample that is typically taken for oxygen and/or nitrogen determination is not suitable for hydrogen determination due to hydrogen loss (diffusion). Surface contamination must be removed by filing or light grinding, using care not to overheat the sample.

Software Features & Benefits

Cornerstone brand software is divided into four main sections—Analysis, Diagnostics, Settings, and Instrument—for simplified navigation and organization. Toolbars, sliders, and drop-down menus makeit easy to set parameters for calibration and data processing. The software also includes real-time ambient monitors, with fully animated system diagrams. Advanced diagnostic features include a thorough digital on-board manual, maintenance animations, photo illustrations, and screen captures that quickly provide the direction needed without having to refer to multiple manuals. also Cornerstone supports extended data archiving and flexible reporting capabilities. 氧氮氢分析仪选哪家？给你推荐上海禹重科技！
