href="http://www.tianhualian.com.cn/ParentList-432788.html" target="_blank">氧化鋯分析儀</a>又稱(chēng)作氧化鋯氧分析儀、氧化鋯氧量計、氧化鋯氧量表等，方便鍋爐操作人員及時(shí)調整鍋爐，提高熱效率，減少排放減低污染，延長(cháng)鍋爐使用壽命。<br /> </div><div>　　一般來(lái)說(shuō)，氧化鋯分析儀和氧化鋯探頭要成套使用，成套使用的好處是廠(chǎng)家已經(jīng)對此匹配調試，可以提高準確性，同時(shí)排除不同廠(chǎng)家的氧化鋯分析儀和氧化鋯探頭不匹配導致的損壞等<br /> </div><div>　　現在我們就教你一招解決氧化鋯分析儀的常見(jiàn)故障<br /> </div><div>　　故障現象一：氧量顯示偏高<br /> </div><div>　　原因1：氧化鋯鋯管破裂漏氣。處理方法：檢查更換鋯管。<br /> </div><div>　　原因2：鋯管產(chǎn)生小裂紋，導致電極部分短路滲透。處理方法：檢查更換。<br /> </div><div>　　原因3：鋯管老化。處理方法：測量鋯管內阻，方法是在儀表規定的工作溫度下，用數字萬(wàn)用表檢測兩電極引線(xiàn)間的阻值，一支新的鋯管內阻應小于50歐姆，如果鋯管內阻大于100歐姆時(shí)，可適當提高爐溫繼續使用。若儀表誤差過(guò)大，超出允許誤差范圍時(shí)，應更換鋯管。</div><p align="center"><img

)造成氧化鋯鋯管內阻過(guò)高。處理方法：檢查校正爐溫。<br /> </div><div>　　故障現象二：氧量值偏低。<br /> </div><div>　　原因1：氧化鋯探頭過(guò)濾器堵塞、導致氣阻增大，影響被測氣體中氧分子的擴散速度。處理方法：反向吹掃、清洗過(guò)濾器，如果不能疏通，則更換過(guò)濾器。<br /> </div><div>　　原因2：存在可燃氣體。氧化鋯固體電解質(zhì)工作在600~850度高溫下將發(fā)生燃燒反應而耗氧，故導致儀表示值偏低。處理方法：應調整工況除去可燃氣體，或者在樣氣中加裝凈化器除去可燃氣體組分。<br /> </div><div>　　原因3：爐溫過(guò)高。處理方法：檢查校正爐溫。<br /> </div><div>　　原因4：量程電勢偏高。處理方法：利用給定電勢差校正量程電勢。</div> </div> <div id="wmcsddy" class="ly_PrevNext"> <ul> <li>上一篇：<a href="/Article-2424074.html">電磁流量計五個(gè)步驟解決零點(diǎn)不穩定現象</a></li> <li>下一篇：<a
