眾所周(zhou)知(zhi)，對于各種(zhong)真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)性能(neng)，都有規定(ding)的(de)(de)(de)(de)(de)(de)(de)測(ce)試方法(fa)來測(ce)試該性能(neng)的(de)(de)(de)(de)(de)(de)(de)性能(neng)，主要性能(neng)是極(ji)限壓力，流(liu)(liu)(liu)量(liang)(liang)和(he)抽(chou)(chou)速(su)。這(zhe)次，小編打算討論螺(luo)桿真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)，例(li)如如何(he)控制(zhi)其流(liu)(liu)(liu)量(liang)(liang)，流(liu)(liu)(liu)量(liang)(liang)不(bu)足(zu)的(de)(de)(de)(de)(de)(de)(de)原因以(yi)及如何(he)消除此問題。相信許(xu)多用戶對這(zhe)些問題感到困惑，不(bu)用擔(dan)心，請(qing)跟隨螺(luo)桿真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)廠(chang)家進(jin)行了解。 首先，讓我們簡單(dan)(dan)介紹一下真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)主要性能(neng)的(de)(de)(de)(de)(de)(de)(de)概念。 1.極(ji)限壓力。真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)與(yu)檢測(ce)容(rong)器(qi)相連，放置待測(ce)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)后，連續長時間(jian)抽(chou)(chou)氣(qi)(qi)(qi)(qi)(qi)(qi)。當容(rong)器(qi)的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)壓不(bu)再降(jiang)低并(bing)且壓力保持(chi)在(zai)(zai)一定(ding)值時，次級壓力就是泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)極(ji)限壓力。 2.流(liu)(liu)(liu)量(liang)(liang)。在(zai)(zai)真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)吸(xi)入口，每單(dan)(dan)位(wei)時間(jian)的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)流(liu)(liu)(liu)量(liang)(liang)稱為泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)。在(zai)(zai)真空(kong)(kong)(kong)(kong)(kong)技術中，流(liu)(liu)(liu)量(liang)(liang)單(dan)(dan)位(wei)以(yi)壓力*體(ti)積/時間(jian)表示(shi)，即Pa.m3/s或Pa.m3/h。通常，泵(beng)(beng)(beng)(beng)會(hui)給(gei)(gei)出流(liu)(liu)(liu)量(liang)(liang)與(yu)入口壓力的(de)(de)(de)(de)(de)(de)(de)關系圖。 3.抽(chou)(chou)速(su)。在(zai)(zai)真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)吸(xi)入口，每單(dan)(dan)位(wei)時間(jian)流(liu)(liu)(liu)動的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)量(liang)(liang)稱為泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)抽(chou)(chou)氣(qi)(qi)(qi)(qi)(qi)(qi)速(su)率(lv)。即，通過將流(liu)(liu)(liu)量(liang)(liang)QA(Pa.m3/s)除以(yi)測(ce)試罩中的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)A的(de)(de)(de)(de)(de)(de)(de)分壓pA而(er)獲得氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)A的(de)(de)(de)(de)(de)(de)(de)泵(beng)(beng)(beng)(beng)送速(su)度sA(m3/s)。典型(xing)的(de)(de)(de)(de)(de)(de)(de)真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)抽(chou)(chou)氣(qi)(qi)(qi)(qi)(qi)(qi)速(su)率(lv)與(yu)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)類型(xing)有關。給(gei)(gei)定(ding)的(de)(de)(de)(de)(de)(de)(de)抽(chou)(chou)氣(qi)(qi)(qi)(qi)(qi)(qi)速(su)率(lv)表示(shi)某種(zhong)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)的(de)(de)(de)(de)(de)(de)(de)抽(chou)(chou)氣(qi)(qi)(qi)(qi)(qi)(qi)速(su)率(lv)。如果沒有特殊指(zhi)示(shi)，則使用多指(zhi)抽(chou)(chou)吸(xi)。 正(zheng)確(que)控制(zhi)螺(luo)桿真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)流(liu)(liu)(liu)量(liang)(liang)不(bu)僅可以(yi)為設(she)備(bei)提供良好的(de)(de)(de)(de)(de)(de)(de)保護，還可以(yi)提高使用率(lv)。那么，該怎(zen)么做呢? 1，速(su)度控制(zhi) 葉輪速(su)度的(de)(de)(de)(de)(de)(de)(de)變(bian)化會(hui)改(gai)變(bian)螺(luo)桿真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)曲線(xian)，并(bing)且曲線(xian)的(de)(de)(de)(de)(de)(de)(de)特性不(bu)會(hui)改(gai)變(bian)。隨著速(su)度降(jiang)低，曲線(xian)變(bian)平，揚程和(he)流(liu)(liu)(liu)速(su)降(jiang)低。 2，旁通閥調整 使用與(yu)泵(beng)(beng)(beng)(beng)并(bing)聯的(de)(de)(de)(de)(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
