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(zhuǎn)子密封口，啟動泵發(fā)現(xiàn)電機正常運轉(zhuǎn)，此時關(guān)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。 為可專利的Cornerstone 氧氮氧分析軟件采用觸摸屏界面使用戶達到分析控制、15法設定、在線診斷、數(shù)據(jù)報告。北京元素分析儀廠家供應

Instrument calibration/drift correction

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

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

h. Press the Analyze button on the instrument screen, the lower electrode will close and the analysis sequence will start and end automatically.

i. Repeat steps 3b through 3h a minimum of three times for each calibration/drift standard used.

. Calibrate/drift following the procedure outlined in the operator's instruction manual.

Procedure - Solid Samples

Determine the instrument blank.

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

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

Instrument calibration/drift correction.

Login a minimum of 3 Standard replicates.

Weigh approximately *** grams of a calibration/drift standard, enter the mass and standard identification into appropriate replicate fields.

Note: LECO Reference Materia***o not require preparation.See preparation statement on the reference material certificate.

Sample Preparation

Sampling and sample preparation of refractory metals such as titanium and zirconium is somewhat different from that of steel. Unlike steel samples, hydrogen is not as mobile in this group of materials; therefore, storage in liquid nitrogen or dry ice is not required. However, it is important to keep the sample cool when cutting or sectioning. Sample preparation for oxygen and nitrogen determination has beendifferent from that of hydrogen determination.
