眾(zhong)所周(zhou)知，對(dui)于(yu)各種真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)性(xing)能(neng)(neng)，都有規(gui)定的(de)(de)測試方法來測試該(gai)性(xing)能(neng)(neng)的(de)(de)性(xing)能(neng)(neng)，主要性(xing)能(neng)(neng)是極(ji)限壓力，流(liu)(liu)量(liang)(liang)(liang)和抽速(su)。這次(ci)，小編打算討(tao)論(lun)螺(luo)桿(gan)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)流(liu)(liu)量(liang)(liang)(liang)，例(li)如(ru)(ru)如(ru)(ru)何控(kong)制其流(liu)(liu)量(liang)(liang)(liang)，流(liu)(liu)量(liang)(liang)(liang)不足的(de)(de)原(yuan)因以(yi)(yi)及如(ru)(ru)何消除(chu)此問(wen)題。相信許(xu)多用戶對(dui)這些(xie)問(wen)題感到困(kun)惑，不用擔心，請跟(gen)隨螺(luo)桿(gan)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)廠家進行了(le)解。 首先，讓我們簡單介紹一下真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)主要性(xing)能(neng)(neng)的(de)(de)概(gai)念(nian)。 1.極(ji)限壓力。真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)與(yu)(yu)檢測容(rong)器(qi)相連，放置(zhi)待(dai)測氣(qi)(qi)(qi)體(ti)(ti)(ti)后(hou)，連續長時間(jian)(jian)抽氣(qi)(qi)(qi)。當(dang)容(rong)器(qi)的(de)(de)氣(qi)(qi)(qi)壓不再(zai)降低并且壓力保持在一定值(zhi)時，次(ci)級壓力就是泵(beng)(beng)(beng)(beng)的(de)(de)極(ji)限壓力。 2.流(liu)(liu)量(liang)(liang)(liang)。在真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)吸(xi)入口(kou)，每單位(wei)時間(jian)(jian)的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)流(liu)(liu)量(liang)(liang)(liang)稱(cheng)為(wei)泵(beng)(beng)(beng)(beng)的(de)(de)流(liu)(liu)量(liang)(liang)(liang)。在真(zhen)(zhen)(zhen)空(kong)(kong)技術中，流(liu)(liu)量(liang)(liang)(liang)單位(wei)以(yi)(yi)壓力*體(ti)(ti)(ti)積/時間(jian)(jian)表(biao)示(shi)，即Pa.m3/s或Pa.m3/h。通(tong)常，泵(beng)(beng)(beng)(beng)會(hui)給出(chu)流(liu)(liu)量(liang)(liang)(liang)與(yu)(yu)入口(kou)壓力的(de)(de)關系圖。 3.抽速(su)。在真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)吸(xi)入口(kou)，每單位(wei)時間(jian)(jian)流(liu)(liu)動的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)量(liang)(liang)(liang)稱(cheng)為(wei)泵(beng)(beng)(beng)(beng)的(de)(de)抽氣(qi)(qi)(qi)速(su)率。即，通(tong)過將流(liu)(liu)量(liang)(liang)(liang)QA(Pa.m3/s)除(chu)以(yi)(yi)測試罩中的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)A的(de)(de)分(fen)壓pA而(er)獲得氣(qi)(qi)(qi)體(ti)(ti)(ti)A的(de)(de)泵(beng)(beng)(beng)(beng)送速(su)度(du)sA(m3/s)。典型的(de)(de)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)抽氣(qi)(qi)(qi)速(su)率與(yu)(yu)氣(qi)(qi)(qi)體(ti)(ti)(ti)類型有關。給定的(de)(de)抽氣(qi)(qi)(qi)速(su)率表(biao)示(shi)某種氣(qi)(qi)(qi)體(ti)(ti)(ti)的(de)(de)抽氣(qi)(qi)(qi)速(su)率。如(ru)(ru)果沒(mei)有特殊指(zhi)示(shi)，則使用多指(zhi)抽吸(xi)。 正確控(kong)制螺(luo)桿(gan)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)流(liu)(liu)量(liang)(liang)(liang)不僅(jin)可(ke)以(yi)(yi)為(wei)設(she)備提(ti)供良(liang)好的(de)(de)保護(hu)，還可(ke)以(yi)(yi)提(ti)高使用率。那么，該(gai)怎么做呢? 1，速(su)度(du)控(kong)制 葉輪(lun)速(su)度(du)的(de)(de)變(bian)化會(hui)改(gai)(gai)變(bian)螺(luo)桿(gan)真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)流(liu)(liu)量(liang)(liang)(liang)曲線，并且曲線的(de)(de)特性(xing)不會(hui)改(gai)(gai)變(bian)。隨著速(su)度(du)降低，曲線變(bian)平，揚程和流(liu)(liu)速(su)降低。 2，旁通(tong)閥調整 使用與(yu)(yu)泵(beng)(beng)(beng)(beng)并聯的(de)(de)中間(jian)(jian)閥。實際效果就...

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
