產(chǎn)品詳情
一批投資少、技術(shù)含量低的雜牌軍以大量低質(zhì)、低價的設(shè)備擠占市場,不僅影響了干燥設(shè)備的整體形象,更引起了國內(nèi)干燥設(shè)備價格的內(nèi)訌,從而使干燥業(yè)的整體競爭能力難以得到發(fā)揮。與干燥設(shè)備行業(yè)的現(xiàn)狀形成反差的是,目前,我國有幾十所高校、科研單位從事干燥技術(shù)的開發(fā)研究,但大部分科研成果沒有轉(zhuǎn)化為現(xiàn)實生產(chǎn)力。專家認為,日益激烈的競爭要求干燥設(shè)備行業(yè)必須主動與科研院所合作,通過技術(shù)進步、自主創(chuàng)新來提升產(chǎn)品的附加值。
不同規(guī)格的薄膜泵流量差別大,從小于1升/分鐘到數(shù)百升/分鐘。由于薄膜泵具有自吸能力,儀器儀表行業(yè)常用的微型薄膜泵也稱為微型真空泵、微型采樣泵。近年來技術(shù)的微型真空泵生產(chǎn)商在電機、隔膜材質(zhì)上取得了突破性的進展,薄膜泵的使用在發(fā)達得到了很大發(fā)展,正逐步占領(lǐng)其它泵的一些領(lǐng)域。相信隨著技術(shù)的進步,薄膜泵在我國的運用必將日益廣泛。目前國內(nèi)低端的微型真空泵多為國貨,進口品牌不占優(yōu)勢。高端微型真空泵主要有進口的KNTHOMAS等品牌和成都氣海品牌。
介紹了圓塊式石墨換熱器的特性及石墨原材料對石墨制化工設(shè)備的影響。結(jié)合PVC生產(chǎn)工藝闡述了石墨制化工設(shè)備在PVC行業(yè)的使用情況。通過傳熱計算,對圓塊式與列管式石墨換熱器的換熱效果進行了對比。[中圖分類號]TQ325.3;TQ51.5[文獻標(biāo)識碼]B[文章編號]19-7937(27)2-3-3石墨換熱器廣泛應(yīng)用于電石乙炔法PVC生產(chǎn)中與HC1氣體或鹽酸相關(guān)的工藝過程。主要設(shè)備有:氯氫處理工段用氯化氫冷卻器,混合冷凍脫水用二級石墨冷卻器,預(yù)熱器及合成氣冷卻器,鹽酸冷卻器,乙烯氧氯化法工藝精餾工段中EDC冷卻器等。
介質(zhì)粘度較大(大于65~1mm2/s)時,可考慮選用轉(zhuǎn)子泵或往復(fù)泵(齒輪泵、.螺桿泵)介質(zhì)含氣量75%,流量較小且粘度小于37.4mm2/s時,可選用旋渦泵。對啟動頻繁或灌泵不便的場合,應(yīng)選用具有自吸性能的泵,如自吸式離心泵、自吸式旋渦泵、氣動。知道泵選型的基本依據(jù)泵選型依據(jù),應(yīng)根據(jù)工藝流程,給排水要求,從五個方面加以考慮,既液體輸送量、裝置揚程、液體性質(zhì)、管路布置以及操作運轉(zhuǎn)條件等流量是選泵的重要性能數(shù)據(jù)之一,它直接關(guān)系到整個裝置的的生產(chǎn)能力和輸送能力。
