馬弗爐的常見故障與解決辦法榮豐科儀建議1、熱電偶開路：關(guān)閉供電電源。打開馬弗爐后蓋。(1)檢查熱電偶末端接線柱與熱電偶引線連接的螺母是否旋緊，要保證兩者接觸良好。(2)檢查熱電偶傳感器本身是否出現(xiàn)開路狀況。(可用儀表測試，例如萬用表)(3)檢查熱電偶末端引線與線路板之間的接插件、接線端子、轉(zhuǎn)接器等是否出現(xiàn)開路或者虛開現(xiàn)象。有時重新插拔一次便可恢復(fù)正常，這是由于安裝工藝或者端子長時間處于較高溫度下而出現(xiàn)的一層氧化層所致。(4)強(qiáng)干擾信號所致，此種情況少見。2、熱電偶接反：關(guān)閉供電電源，打開馬弗爐后蓋，檢查熱電偶末端的極性和控制器熱電偶輸入端口的極性經(jīng)過線路連接后是否一致。(可用目測法和儀表測試法)3、通信中斷：檢查控制器外部的線路接口是否脫落或接觸不良(如九針串口、航空插頭等連接處)，要保證其連接可靠接觸良好。4、觸摸功能無效：(1)檢查顯示器排線是否接觸良好。打開控制器外殼，檢查顯示屏與控制板之間的顯示排線是否老化或者接觸不良。有時將顯示排線兩端的接口處重新插拔一次便可恢復(fù)正常。(2)顯示排線問題或者顯示屏問題。與廠家更換。5、顯示屏無顯示(黑屏)：(1)檢查控制器的供電接口是否脫落或者松動。。</p><p> 實驗室馬弗爐說明使用本儀器前請仔細(xì)閱讀以下注意事項：當(dāng)馬弗爐初次次使用或長期停用后再次使用時，必須進(jìn)行烘爐干燥：在20～200℃打開爐門烘2-3h，200～600℃關(guān)門烘2-3h。實驗前，溫控器應(yīng)避免震動，放置位置與電爐不宜太近，防止過熱使電子元件不能正常工作。搬動溫控器時應(yīng)將電源開關(guān)置“關(guān)”。使用前，將溫控器調(diào)至所需工作溫度，打開啟動編碼使馬弗爐通電，此時電流表有讀數(shù)產(chǎn)生，溫控表實測溫度值逐漸上升，表示馬弗爐、溫控器均在正常工作。實驗室馬弗爐描述(一)工作環(huán)境要求無易燃易爆物品和腐蝕性氣體，禁止向爐膛內(nèi)直接灌注各種液體及熔解金屬，經(jīng)常保持爐膛內(nèi)的清潔。(二)使用時爐膛溫度不得超過比較高爐溫，也不得在額定溫度下長時間工作。實驗過程中，使用人不得離開，隨時注意溫度的變，如發(fā)現(xiàn)異常情況，應(yīng)立即斷電，并由專業(yè)人員檢修。(三)使用時爐門要輕關(guān)輕開，以防損壞機(jī)件。坩堝鉗放取樣品時要輕拿輕放，以全和避免損壞爐膛。(四)溫度超過600度后不要打開爐門。等爐膛內(nèi)溫度自然冷卻后再打開爐門。(五)實驗完畢后，樣品退出加熱并關(guān)掉電源，在爐膛內(nèi)放取樣品時，應(yīng)先微開爐門，待樣品稍冷卻后再小心夾取樣品，防止?fàn)C傷。。800℃的馬弗爐屬于常規(guī)產(chǎn)品。馬弗爐較大范圍用于陶瓷、冶金、電子、玻璃、化工、機(jī)械、耐火材料、特種材料、建材等領(lǐng)域的生產(chǎn)及實驗。</p><div
