眾所周知，對于各種真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)性(xing)能(neng)，都有(you)規定的(de)測試(shi)(shi)方法來測試(shi)(shi)該性(xing)能(neng)的(de)性(xing)能(neng)，主要性(xing)能(neng)是極限壓(ya)(ya)(ya)(ya)力，流(liu)(liu)(liu)(liu)量和抽速(su)(su)。這(zhe)次(ci)，小編打(da)算討(tao)論螺(luo)桿(gan)(gan)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)流(liu)(liu)(liu)(liu)量，例如(ru)如(ru)何控制(zhi)(zhi)其流(liu)(liu)(liu)(liu)量，流(liu)(liu)(liu)(liu)量不(bu)(bu)足的(de)原(yuan)因以(yi)(yi)及如(ru)何消除此問題。相(xiang)(xiang)信許多(duo)用戶(hu)對這(zhe)些(xie)問題感到困(kun)惑，不(bu)(bu)用擔心，請跟(gen)隨(sui)螺(luo)桿(gan)(gan)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)廠家進行(xing)了解。 首(shou)先(xian)，讓(rang)我們簡單(dan)介紹一下真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)主要性(xing)能(neng)的(de)概念。 1.極限壓(ya)(ya)(ya)(ya)力。真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)與(yu)檢(jian)測容器相(xiang)(xiang)連(lian)，放(fang)置待測氣(qi)體(ti)(ti)后，連(lian)續(xu)長(chang)時(shi)間抽氣(qi)。當容器的(de)氣(qi)壓(ya)(ya)(ya)(ya)不(bu)(bu)再降低(di)(di)并(bing)且壓(ya)(ya)(ya)(ya)力保(bao)(bao)持在(zai)(zai)一定值時(shi)，次(ci)級壓(ya)(ya)(ya)(ya)力就(jiu)是泵(beng)(beng)(beng)的(de)極限壓(ya)(ya)(ya)(ya)力。 2.流(liu)(liu)(liu)(liu)量。在(zai)(zai)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)吸入口，每(mei)(mei)單(dan)位時(shi)間的(de)氣(qi)體(ti)(ti)流(liu)(liu)(liu)(liu)量稱(cheng)為泵(beng)(beng)(beng)的(de)流(liu)(liu)(liu)(liu)量。在(zai)(zai)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)技(ji)術中(zhong)(zhong)，流(liu)(liu)(liu)(liu)量單(dan)位以(yi)(yi)壓(ya)(ya)(ya)(ya)力*體(ti)(ti)積(ji)/時(shi)間表示(shi)，即Pa.m3/s或Pa.m3/h。通常(chang)，泵(beng)(beng)(beng)會給出流(liu)(liu)(liu)(liu)量與(yu)入口壓(ya)(ya)(ya)(ya)力的(de)關(guan)系(xi)圖。 3.抽速(su)(su)。在(zai)(zai)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)吸入口，每(mei)(mei)單(dan)位時(shi)間流(liu)(liu)(liu)(liu)動的(de)氣(qi)體(ti)(ti)量稱(cheng)為泵(beng)(beng)(beng)的(de)抽氣(qi)速(su)(su)率。即，通過將(jiang)流(liu)(liu)(liu)(liu)量QA(Pa.m3/s)除以(yi)(yi)測試(shi)(shi)罩中(zhong)(zhong)的(de)氣(qi)體(ti)(ti)A的(de)分(fen)壓(ya)(ya)(ya)(ya)pA而獲得(de)氣(qi)體(ti)(ti)A的(de)泵(beng)(beng)(beng)送速(su)(su)度sA(m3/s)。典型的(de)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)抽氣(qi)速(su)(su)率與(yu)氣(qi)體(ti)(ti)類型有(you)關(guan)。給定的(de)抽氣(qi)速(su)(su)率表示(shi)某種氣(qi)體(ti)(ti)的(de)抽氣(qi)速(su)(su)率。如(ru)果(guo)沒(mei)有(you)特(te)殊指示(shi)，則使用多(duo)指抽吸。 正確控制(zhi)(zhi)螺(luo)桿(gan)(gan)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)流(liu)(liu)(liu)(liu)量不(bu)(bu)僅可以(yi)(yi)為設備提(ti)(ti)供(gong)良好的(de)保(bao)(bao)護，還可以(yi)(yi)提(ti)(ti)高使用率。那么，該怎么做呢? 1，速(su)(su)度控制(zhi)(zhi) 葉輪(lun)速(su)(su)度的(de)變(bian)化(hua)會改變(bian)螺(luo)桿(gan)(gan)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)流(liu)(liu)(liu)(liu)量曲(qu)線，并(bing)且曲(qu)線的(de)特(te)性(xing)不(bu)(bu)會改變(bian)。隨(sui)著速(su)(su)度降低(di)(di)，曲(qu)線變(bian)平，揚程和流(liu)(liu)(liu)(liu)速(su)(su)降低(di)(di)。 2，旁(pang)通閥(fa)調整 使用與(yu)泵(beng)(beng)(beng)并(bing)聯(lian)的(de)中(zhong)(zhong)間閥(fa)。實(shi)際效(xiao)果(guo)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過濾器。 5.更換水環真空泵口環，調整軸向間隙，以防止葉輪口環和軸向間隙不合適。使用時，請?
