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。 北京美国LECO分析仪咨询报价新型气路管道减少气路连接阀，使得漏气，断路故障更少。

Determine the instrument blank.

a. Login a minimum of 3 Blank replicates.

b. Press the Analyze button on the instrument screen. After a short delay, the loading head slide-block will open.

c. Press the Analyze button on the instrument screen again, the loading head slide-block will close and the lower electrode will open.

d. Clean the upper and lower electrode manually, or, if applicable, remove thecrucible and press the analyze button to clean with the automatic cleaner.

e. Firmly place a graphite crucible on the lower electrode tip.

f. Press the Analyze button on the instrument screen, the lower electrode will close and the analysis sequence will start and endautomatically.

g. Repeat steps 2b through 2f a minimum of three times.

h. Set the blank following the procedure outlined in the operator's instruction manual.

Procedure - Solid Samples

Prepare the instrument as outlined in the operator's instruction manual.

Determine the instrument blank.

Login a minimum of 3 Blank replicates.

Press the Analyze button on the instrument screen. After a short delay, the loading head slide-block will open. Place a 502-344 Nickel Basket into the loading head.

Note: samples using automation should be placed in the appropriate autoloader position before starting the

analysis sequence. Once the sequence has started, the automatic analysis will start and end automatically.
