眾所周知，對于(yu)各種真(zhen)(zhen)空泵(beng)(beng)(beng)的(de)(de)性能(neng)(neng)，都(dou)有(you)(you)規定(ding)的(de)(de)測(ce)試(shi)方法來(lai)測(ce)試(shi)該(gai)性能(neng)(neng)的(de)(de)性能(neng)(neng)，主(zhu)(zhu)要(yao)性能(neng)(neng)是極限壓(ya)(ya)(ya)力(li)(li)(li)，流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)和(he)抽速(su)。這(zhe)次(ci)，小編打(da)算討論螺(luo)桿真(zhen)(zhen)空泵(beng)(beng)(beng)的(de)(de)流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)，例如如何(he)控(kong)制其流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)，流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)不足(zu)的(de)(de)原因以及如何(he)消除此問題(ti)。相信許多用(yong)(yong)戶對這(zhe)些問題(ti)感到困惑，不用(yong)(yong)擔(dan)心，請跟(gen)隨螺(luo)桿真(zhen)(zhen)空泵(beng)(beng)(beng)廠家進行了解。 首先，讓我們(men)簡單(dan)介紹一(yi)下真(zhen)(zhen)空泵(beng)(beng)(beng)主(zhu)(zhu)要(yao)性能(neng)(neng)的(de)(de)概念。 1.極限壓(ya)(ya)(ya)力(li)(li)(li)。真(zhen)(zhen)空泵(beng)(beng)(beng)與(yu)檢測(ce)容器相連，放置待測(ce)氣(qi)體后，連續(xu)長時間抽氣(qi)。當容器的(de)(de)氣(qi)壓(ya)(ya)(ya)不再降低并(bing)且壓(ya)(ya)(ya)力(li)(li)(li)保持在一(yi)定(ding)值時，次(ci)級壓(ya)(ya)(ya)力(li)(li)(li)就(jiu)是泵(beng)(beng)(beng)的(de)(de)極限壓(ya)(ya)(ya)力(li)(li)(li)。 2.流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)。在真(zhen)(zhen)空泵(beng)(beng)(beng)的(de)(de)吸入(ru)口(kou)，每單(dan)位時間的(de)(de)氣(qi)體流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)稱為(wei)泵(beng)(beng)(beng)的(de)(de)流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)。在真(zhen)(zhen)空技術中(zhong)，流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)單(dan)位以壓(ya)(ya)(ya)力(li)(li)(li)*體積(ji)/時間表示(shi)，即(ji)Pa.m3/s或(huo)Pa.m3/h。通(tong)(tong)常，泵(beng)(beng)(beng)會給出流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)與(yu)入(ru)口(kou)壓(ya)(ya)(ya)力(li)(li)(li)的(de)(de)關系圖(tu)。 3.抽速(su)。在真(zhen)(zhen)空泵(beng)(beng)(beng)的(de)(de)吸入(ru)口(kou)，每單(dan)位時間流(liu)(liu)(liu)(liu)動的(de)(de)氣(qi)體量(liang)(liang)(liang)(liang)稱為(wei)泵(beng)(beng)(beng)的(de)(de)抽氣(qi)速(su)率(lv)。即(ji)，通(tong)(tong)過(guo)將流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)QA(Pa.m3/s)除以測(ce)試(shi)罩中(zhong)的(de)(de)氣(qi)體A的(de)(de)分壓(ya)(ya)(ya)pA而獲(huo)得氣(qi)體A的(de)(de)泵(beng)(beng)(beng)送(song)速(su)度sA(m3/s)。典型的(de)(de)真(zhen)(zhen)空泵(beng)(beng)(beng)的(de)(de)抽氣(qi)速(su)率(lv)與(yu)氣(qi)體類型有(you)(you)關。給定(ding)的(de)(de)抽氣(qi)速(su)率(lv)表示(shi)某種氣(qi)體的(de)(de)抽氣(qi)速(su)率(lv)。如果沒有(you)(you)特殊指(zhi)示(shi)，則(ze)使用(yong)(yong)多指(zhi)抽吸。 正確控(kong)制螺(luo)桿真(zhen)(zhen)空泵(beng)(beng)(beng)流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)不僅可(ke)以為(wei)設備提供良好的(de)(de)保護，還可(ke)以提高(gao)使用(yong)(yong)率(lv)。那么，該(gai)怎么做呢? 1，速(su)度控(kong)制 葉輪速(su)度的(de)(de)變(bian)(bian)化會改變(bian)(bian)螺(luo)桿真(zhen)(zhen)空泵(beng)(beng)(beng)的(de)(de)流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)曲(qu)線，并(bing)且曲(qu)線的(de)(de)特性不會改變(bian)(bian)。隨著(zhu)速(su)度降低，曲(qu)線變(bian)(bian)平，揚程和(he)流(liu)(liu)(liu)(liu)速(su)降低。 2，旁通(tong)(tong)閥調整(zheng) 使用(yong)(yong)與(yu)泵(beng)(beng)(beng)并(bing)聯(lian)的(de)(de)中(zhong)間閥。實際(ji)效果就(jiu)...

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，則可以卸下水環真空泵?
