眾所周(zhou)知，對于各種真空泵(beng)的(de)(de)(de)性(xing)能(neng)(neng)(neng)，都(dou)有(you)規定(ding)(ding)的(de)(de)(de)測(ce)(ce)試方法來測(ce)(ce)試該(gai)性(xing)能(neng)(neng)(neng)的(de)(de)(de)性(xing)能(neng)(neng)(neng)，主(zhu)要性(xing)能(neng)(neng)(neng)是極限壓(ya)力，流(liu)(liu)(liu)(liu)量(liang)(liang)和(he)抽速(su)(su)。這次，小編(bian)打算討論螺桿真空泵(beng)的(de)(de)(de)流(liu)(liu)(liu)(liu)量(liang)(liang)，例(li)如如何(he)控(kong)制(zhi)其流(liu)(liu)(liu)(liu)量(liang)(liang)，流(liu)(liu)(liu)(liu)量(liang)(liang)不(bu)足的(de)(de)(de)原因(yin)以(yi)及如何(he)消除此問(wen)題。相信許多(duo)用(yong)(yong)戶對這些問(wen)題感到困惑，不(bu)用(yong)(yong)擔心，請跟隨螺桿真空泵(beng)廠(chang)家進行了解。 首先(xian)，讓我們簡(jian)單介紹(shao)一(yi)下真空泵(beng)主(zhu)要性(xing)能(neng)(neng)(neng)的(de)(de)(de)概念(nian)。 1.極限壓(ya)力。真空泵(beng)與(yu)檢測(ce)(ce)容(rong)器相連，放置待測(ce)(ce)氣(qi)(qi)(qi)體(ti)后，連續長時(shi)間(jian)抽氣(qi)(qi)(qi)。當容(rong)器的(de)(de)(de)氣(qi)(qi)(qi)壓(ya)不(bu)再降(jiang)低并且(qie)壓(ya)力保持在(zai)(zai)一(yi)定(ding)(ding)值時(shi)，次級壓(ya)力就是泵(beng)的(de)(de)(de)極限壓(ya)力。 2.流(liu)(liu)(liu)(liu)量(liang)(liang)。在(zai)(zai)真空泵(beng)的(de)(de)(de)吸(xi)入(ru)(ru)口(kou)，每單位時(shi)間(jian)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)流(liu)(liu)(liu)(liu)量(liang)(liang)稱為泵(beng)的(de)(de)(de)流(liu)(liu)(liu)(liu)量(liang)(liang)。在(zai)(zai)真空技(ji)術中，流(liu)(liu)(liu)(liu)量(liang)(liang)單位以(yi)壓(ya)力*體(ti)積/時(shi)間(jian)表示，即Pa.m3/s或(huo)Pa.m3/h。通常(chang)，泵(beng)會給(gei)出流(liu)(liu)(liu)(liu)量(liang)(liang)與(yu)入(ru)(ru)口(kou)壓(ya)力的(de)(de)(de)關(guan)系圖(tu)。 3.抽速(su)(su)。在(zai)(zai)真空泵(beng)的(de)(de)(de)吸(xi)入(ru)(ru)口(kou)，每單位時(shi)間(jian)流(liu)(liu)(liu)(liu)動的(de)(de)(de)氣(qi)(qi)(qi)體(ti)量(liang)(liang)稱為泵(beng)的(de)(de)(de)抽氣(qi)(qi)(qi)速(su)(su)率(lv)。即，通過將流(liu)(liu)(liu)(liu)量(liang)(liang)QA(Pa.m3/s)除以(yi)測(ce)(ce)試罩中的(de)(de)(de)氣(qi)(qi)(qi)體(ti)A的(de)(de)(de)分壓(ya)pA而獲得氣(qi)(qi)(qi)體(ti)A的(de)(de)(de)泵(beng)送速(su)(su)度(du)(du)sA(m3/s)。典(dian)型(xing)(xing)的(de)(de)(de)真空泵(beng)的(de)(de)(de)抽氣(qi)(qi)(qi)速(su)(su)率(lv)與(yu)氣(qi)(qi)(qi)體(ti)類型(xing)(xing)有(you)關(guan)。給(gei)定(ding)(ding)的(de)(de)(de)抽氣(qi)(qi)(qi)速(su)(su)率(lv)表示某種氣(qi)(qi)(qi)體(ti)的(de)(de)(de)抽氣(qi)(qi)(qi)速(su)(su)率(lv)。如果沒有(you)特(te)殊指示，則使用(yong)(yong)多(duo)指抽吸(xi)。 正(zheng)確控(kong)制(zhi)螺桿真空泵(beng)流(liu)(liu)(liu)(liu)量(liang)(liang)不(bu)僅可以(yi)為設備(bei)提供良好的(de)(de)(de)保護，還可以(yi)提高使用(yong)(yong)率(lv)。那么(me)，該(gai)怎么(me)做呢? 1，速(su)(su)度(du)(du)控(kong)制(zhi) 葉(xie)輪速(su)(su)度(du)(du)的(de)(de)(de)變(bian)化會改(gai)變(bian)螺桿真空泵(beng)的(de)(de)(de)流(liu)(liu)(liu)(liu)量(liang)(liang)曲(qu)線，并且(qie)曲(qu)線的(de)(de)(de)特(te)性(xing)不(bu)會改(gai)變(bian)。隨著(zhu)速(su)(su)度(du)(du)降(jiang)低，曲(qu)線變(bian)平(ping)，揚程和(he)流(liu)(liu)(liu)(liu)速(su)(su)降(jiang)低。 2，旁通閥調(diao)整 使用(yong)(yong)與(yu)泵(beng)并聯(lian)的(de)(de)(de)中間(jian)閥。實際效(xiao)果就...

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.如果可以保持進水清潔，則可以卸下水環?
