style="text-indent:25px">愛德華真空泵有哪些特點？在較寬的壓力范圍內(nèi)有較大的抽速；轉(zhuǎn)子具有良好的幾何對稱性，故振動小，運轉(zhuǎn)平穩(wěn)。轉(zhuǎn)子間及轉(zhuǎn)子和殼體間均有間隙，不用潤滑，摩擦損失小，可較大降低驅(qū)動功率，從而可實現(xiàn)較高轉(zhuǎn)速；泵腔內(nèi)無需用油密封和潤滑，可減少油蒸氣對真空系統(tǒng)的污染；泵腔內(nèi)無壓縮，無排氣閥。結(jié)構(gòu)簡單、緊湊，對被抽氣體中的灰塵和水蒸汽不敏感；壓縮比較低，對氫氣抽氣效果差；轉(zhuǎn)子表面為形狀較為復雜的曲線柱面，加工和檢查比較困難。氦質(zhì)譜檢漏儀真空泵供貨費用愛德華真空泵的重心較高，在高速運轉(zhuǎn)時穩(wěn)定性差，故這種型式多用于小泵。</p><div

style="text-indent:25px">愛德華真空泵用來抽除密閉容器的氣體的基本設備之一。它可以單獨使用，也可作為增壓泵、擴散泵、分子泵的前級泵使用。該型泵普遍應用于冶金、機械、電子、化工、石油、醫(yī)藥等行業(yè)的真空冶煉、真空鍍膜、真空熱處理，真空干燥等工藝過程中。旋片式愛德華真空泵具有結(jié)構(gòu)緊湊，體積小，重量輕，噪音低，振動小等優(yōu)點。所以，它適用于作擴散泵的前級泵，而且更適用于精密儀器配套和實驗室使用。例如：質(zhì)譜儀器，冰箱流水線，真空冷凍干燥機等。</p><p style="text-indent:25px">德華真空泵油的極限全壓力和極限分壓力：由皮拉尼計或熱偶真空計測出愛德華真空泵一切物質(zhì)（氣體）產(chǎn)生壓強的總和。國外目前注重全壓強的測試指標。極限分壓力：用**緊縮式真空計（麥氏計）測得的泵的極限空氣分壓力，雙級旋片泵分壓力應為≤6×10-5kPa。極限全壓力與極限分壓力差值請求不大于一個數(shù)量級。二者之間的差值越大，愛德華真空泵油中含有的揮發(fā)成分就越多，油品的性質(zhì)就越差。愛德華真空泵油的光滑性，摩擦面的磨擦磨損、外表疲倦磨損以及腐蝕磨損等，都與光滑條件有關。表現(xiàn)佳的愛德華真空泵油有利于抑止腐蝕磨損；能夠有效地減輕粘著磨損和外表疲倦磨損；流體光滑劑對摩擦面具有清洗作用，也可減輕磨擦磨損。降低摩擦阻力以節(jié)約能源，減少磨損，以延長機械壽命。愛德華真空泵的工作原理，愛德華真空泵基本上可以分為兩種類型，即氣體捕集泵和氣體傳輸泵。</p><div
