眾所(suo)周知，對于各種(zhong)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)性能(neng)，都有(you)規(gui)定(ding)的(de)(de)(de)測(ce)(ce)試方法(fa)來測(ce)(ce)試該性能(neng)的(de)(de)(de)性能(neng)，主要性能(neng)是極(ji)限(xian)壓(ya)(ya)力，流(liu)量(liang)和抽(chou)速(su)(su)。這(zhe)次，小(xiao)編打算討論螺(luo)(luo)桿真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)流(liu)量(liang)，例(li)如(ru)如(ru)何(he)控(kong)制(zhi)其流(liu)量(liang)，流(liu)量(liang)不足的(de)(de)(de)原因以及如(ru)何(he)消除此問題(ti)。相(xiang)信許多(duo)用戶(hu)對這(zhe)些(xie)問題(ti)感到困惑，不用擔心，請跟(gen)隨螺(luo)(luo)桿真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)廠家(jia)進行了解。 首先，讓我們簡單(dan)(dan)介紹一(yi)(yi)下真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)主要性能(neng)的(de)(de)(de)概念。 1.極(ji)限(xian)壓(ya)(ya)力。真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)與(yu)(yu)檢測(ce)(ce)容(rong)器相(xiang)連，放置(zhi)待測(ce)(ce)氣(qi)(qi)(qi)體(ti)(ti)后，連續長時間抽(chou)氣(qi)(qi)(qi)。當容(rong)器的(de)(de)(de)氣(qi)(qi)(qi)壓(ya)(ya)不再降低(di)并且壓(ya)(ya)力保(bao)(bao)持在一(yi)(yi)定(ding)值時，次級壓(ya)(ya)力就是泵(beng)(beng)(beng)(beng)的(de)(de)(de)極(ji)限(xian)壓(ya)(ya)力。 2.流(liu)量(liang)。在真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)吸入(ru)口，每單(dan)(dan)位時間的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)流(liu)量(liang)稱為泵(beng)(beng)(beng)(beng)的(de)(de)(de)流(liu)量(liang)。在真(zhen)(zhen)(zhen)空(kong)(kong)技術中，流(liu)量(liang)單(dan)(dan)位以壓(ya)(ya)力*體(ti)(ti)積/時間表(biao)示，即(ji)Pa.m3/s或Pa.m3/h。通常(chang)，泵(beng)(beng)(beng)(beng)會給出(chu)流(liu)量(liang)與(yu)(yu)入(ru)口壓(ya)(ya)力的(de)(de)(de)關系圖。 3.抽(chou)速(su)(su)。在真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)吸入(ru)口，每單(dan)(dan)位時間流(liu)動的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)量(liang)稱為泵(beng)(beng)(beng)(beng)的(de)(de)(de)抽(chou)氣(qi)(qi)(qi)速(su)(su)率。即(ji)，通過(guo)將流(liu)量(liang)QA(Pa.m3/s)除以測(ce)(ce)試罩中的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)A的(de)(de)(de)分壓(ya)(ya)pA而獲得(de)氣(qi)(qi)(qi)體(ti)(ti)A的(de)(de)(de)泵(beng)(beng)(beng)(beng)送速(su)(su)度sA(m3/s)。典型的(de)(de)(de)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)抽(chou)氣(qi)(qi)(qi)速(su)(su)率與(yu)(yu)氣(qi)(qi)(qi)體(ti)(ti)類(lei)型有(you)關。給定(ding)的(de)(de)(de)抽(chou)氣(qi)(qi)(qi)速(su)(su)率表(biao)示某種(zhong)氣(qi)(qi)(qi)體(ti)(ti)的(de)(de)(de)抽(chou)氣(qi)(qi)(qi)速(su)(su)率。如(ru)果(guo)沒有(you)特殊指示，則(ze)使(shi)(shi)用多(duo)指抽(chou)吸。 正確控(kong)制(zhi)螺(luo)(luo)桿真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)流(liu)量(liang)不僅可以為設備(bei)提供(gong)良(liang)好的(de)(de)(de)保(bao)(bao)護(hu)，還可以提高使(shi)(shi)用率。那么(me)，該怎么(me)做呢? 1，速(su)(su)度控(kong)制(zhi) 葉輪速(su)(su)度的(de)(de)(de)變(bian)(bian)化會改變(bian)(bian)螺(luo)(luo)桿真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)流(liu)量(liang)曲線(xian)(xian)，并且曲線(xian)(xian)的(de)(de)(de)特性不會改變(bian)(bian)。隨著速(su)(su)度降低(di)，曲線(xian)(xian)變(bian)(bian)平，揚程和流(liu)速(su)(su)降低(di)。 2，旁通閥調整 使(shi)(shi)用與(yu)(yu)泵(beng)(beng)(beng)(beng)并聯的(de)(de)(de)中間閥。實(shi)際效(xiao)果(guo)就...

水環真空泵一直非常關注粗糙真空的獲得，例如真空過濾，真空水轉移，真空蒸發等。它已廣泛用于工業生產的許多過程中。 為了節約能源，有必要盡可能地節約能源。我們如何使用水環真空泵來節能? 1. 水環真空泵對角安裝，以減小彎頭或蝸殼，使水口面向水池。 2.縮短水環真空泵管道，拆除1米長的鋼管，并在10小時內節省0.21千克柴油。 3.擴大水環真空泵的出口管直徑。例如，將15米長的4米長水管替換為15厘米長的管道，并節省10公斤柴油10小時。 4.如果可以保持進水?
