眾所(suo)周知，對于各(ge)種真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)性(xing)能，都有規定(ding)的(de)(de)(de)(de)(de)測(ce)(ce)試方法來測(ce)(ce)試該(gai)性(xing)能的(de)(de)(de)(de)(de)性(xing)能，主(zhu)要(yao)性(xing)能是極(ji)限壓(ya)力，流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)和抽(chou)速(su)。這次(ci)(ci)，小編(bian)打算討(tao)論(lun)螺(luo)(luo)桿(gan)(gan)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)，例如(ru)如(ru)何(he)控制(zhi)其流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)，流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)不(bu)(bu)(bu)足的(de)(de)(de)(de)(de)原因以(yi)及如(ru)何(he)消除此問題。相信(xin)許多用(yong)戶對這些問題感到(dao)困惑(huo)，不(bu)(bu)(bu)用(yong)擔(dan)心，請跟隨螺(luo)(luo)桿(gan)(gan)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)廠家進行了解。 首先，讓我們簡(jian)單介紹一下真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)主(zhu)要(yao)性(xing)能的(de)(de)(de)(de)(de)概念。 1.極(ji)限壓(ya)力。真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)與(yu)檢(jian)測(ce)(ce)容(rong)器相連，放(fang)置待測(ce)(ce)氣(qi)(qi)(qi)體(ti)(ti)(ti)后，連續(xu)長時間(jian)抽(chou)氣(qi)(qi)(qi)。當容(rong)器的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)壓(ya)不(bu)(bu)(bu)再降低并且壓(ya)力保持在(zai)(zai)一定(ding)值時，次(ci)(ci)級壓(ya)力就是泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)極(ji)限壓(ya)力。 2.流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)。在(zai)(zai)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)吸入口(kou)，每(mei)單位時間(jian)的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)稱為(wei)(wei)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)。在(zai)(zai)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)技術中(zhong)(zhong)，流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)單位以(yi)壓(ya)力*體(ti)(ti)(ti)積/時間(jian)表示(shi)(shi)，即Pa.m3/s或Pa.m3/h。通常，泵(beng)(beng)(beng)會給出(chu)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)與(yu)入口(kou)壓(ya)力的(de)(de)(de)(de)(de)關系圖。 3.抽(chou)速(su)。在(zai)(zai)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)吸入口(kou)，每(mei)單位時間(jian)流(liu)(liu)(liu)動(dong)的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)量(liang)(liang)(liang)(liang)(liang)稱為(wei)(wei)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)抽(chou)氣(qi)(qi)(qi)速(su)率(lv)(lv)。即，通過將(jiang)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)QA(Pa.m3/s)除以(yi)測(ce)(ce)試罩(zhao)中(zhong)(zhong)的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)A的(de)(de)(de)(de)(de)分(fen)壓(ya)pA而(er)獲(huo)得氣(qi)(qi)(qi)體(ti)(ti)(ti)A的(de)(de)(de)(de)(de)泵(beng)(beng)(beng)送速(su)度(du)sA(m3/s)。典型的(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)抽(chou)氣(qi)(qi)(qi)速(su)率(lv)(lv)與(yu)氣(qi)(qi)(qi)體(ti)(ti)(ti)類(lei)型有關。給定(ding)的(de)(de)(de)(de)(de)抽(chou)氣(qi)(qi)(qi)速(su)率(lv)(lv)表示(shi)(shi)某種氣(qi)(qi)(qi)體(ti)(ti)(ti)的(de)(de)(de)(de)(de)抽(chou)氣(qi)(qi)(qi)速(su)率(lv)(lv)。如(ru)果(guo)(guo)沒有特殊指(zhi)示(shi)(shi)，則使(shi)用(yong)多指(zhi)抽(chou)吸。 正確控制(zhi)螺(luo)(luo)桿(gan)(gan)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)不(bu)(bu)(bu)僅可以(yi)為(wei)(wei)設備(bei)提供良好的(de)(de)(de)(de)(de)保護，還可以(yi)提高使(shi)用(yong)率(lv)(lv)。那么，該(gai)怎么做呢? 1，速(su)度(du)控制(zhi) 葉輪速(su)度(du)的(de)(de)(de)(de)(de)變化會改變螺(luo)(luo)桿(gan)(gan)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)曲線(xian)，并且曲線(xian)的(de)(de)(de)(de)(de)特性(xing)不(bu)(bu)(bu)會改變。隨著速(su)度(du)降低，曲線(xian)變平，揚程和流(liu)(liu)(liu)速(su)降低。 2，旁通閥調整 使(shi)用(yong)與(yu)泵(beng)(beng)(beng)并聯的(de)(de)(de)(de)(de)中(zhong)(zhong)間(jian)閥。實際效果(guo)(guo)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，?
