眾(zhong)所(suo)周知，對于各種真(zhen)(zhen)空(kong)(kong)泵(beng)的(de)(de)(de)(de)(de)(de)性(xing)能，都有(you)(you)規定的(de)(de)(de)(de)(de)(de)測試(shi)(shi)方法來(lai)測試(shi)(shi)該(gai)性(xing)能的(de)(de)(de)(de)(de)(de)性(xing)能，主(zhu)要性(xing)能是(shi)極限壓(ya)(ya)(ya)力(li)(li)，流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)和抽(chou)速(su)(su)。這(zhe)次，小編打算(suan)討論螺桿(gan)(gan)真(zhen)(zhen)空(kong)(kong)泵(beng)的(de)(de)(de)(de)(de)(de)流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)，例如(ru)(ru)如(ru)(ru)何(he)控(kong)制(zhi)(zhi)其流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)，流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)不(bu)(bu)足的(de)(de)(de)(de)(de)(de)原因以及如(ru)(ru)何(he)消除(chu)此(ci)問題。相(xiang)信許多用(yong)戶對這(zhe)些問題感到困惑，不(bu)(bu)用(yong)擔心，請跟(gen)隨螺桿(gan)(gan)真(zhen)(zhen)空(kong)(kong)泵(beng)廠家進(jin)行了解。 首(shou)先，讓我們簡單(dan)介紹(shao)一下真(zhen)(zhen)空(kong)(kong)泵(beng)主(zhu)要性(xing)能的(de)(de)(de)(de)(de)(de)概念。 1.極限壓(ya)(ya)(ya)力(li)(li)。真(zhen)(zhen)空(kong)(kong)泵(beng)與(yu)檢測容器相(xiang)連，放置待測氣(qi)(qi)體(ti)(ti)后，連續(xu)長時(shi)(shi)間(jian)抽(chou)氣(qi)(qi)。當容器的(de)(de)(de)(de)(de)(de)氣(qi)(qi)壓(ya)(ya)(ya)不(bu)(bu)再降(jiang)低(di)并且壓(ya)(ya)(ya)力(li)(li)保持在(zai)一定值時(shi)(shi)，次級壓(ya)(ya)(ya)力(li)(li)就是(shi)泵(beng)的(de)(de)(de)(de)(de)(de)極限壓(ya)(ya)(ya)力(li)(li)。 2.流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)。在(zai)真(zhen)(zhen)空(kong)(kong)泵(beng)的(de)(de)(de)(de)(de)(de)吸入口(kou)，每單(dan)位時(shi)(shi)間(jian)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)稱為泵(beng)的(de)(de)(de)(de)(de)(de)流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)。在(zai)真(zhen)(zhen)空(kong)(kong)技術中，流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)單(dan)位以壓(ya)(ya)(ya)力(li)(li)*體(ti)(ti)積/時(shi)(shi)間(jian)表示，即Pa.m3/s或Pa.m3/h。通常，泵(beng)會給(gei)出流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)與(yu)入口(kou)壓(ya)(ya)(ya)力(li)(li)的(de)(de)(de)(de)(de)(de)關(guan)系(xi)圖。 3.抽(chou)速(su)(su)。在(zai)真(zhen)(zhen)空(kong)(kong)泵(beng)的(de)(de)(de)(de)(de)(de)吸入口(kou)，每單(dan)位時(shi)(shi)間(jian)流(liu)(liu)(liu)(liu)動的(de)(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)量(liang)(liang)(liang)(liang)稱為泵(beng)的(de)(de)(de)(de)(de)(de)抽(chou)氣(qi)(qi)速(su)(su)率(lv)(lv)。即，通過將流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)QA(Pa.m3/s)除(chu)以測試(shi)(shi)罩中的(de)(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)A的(de)(de)(de)(de)(de)(de)分壓(ya)(ya)(ya)pA而獲得氣(qi)(qi)體(ti)(ti)A的(de)(de)(de)(de)(de)(de)泵(beng)送速(su)(su)度(du)(du)sA(m3/s)。典型(xing)的(de)(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong)(kong)泵(beng)的(de)(de)(de)(de)(de)(de)抽(chou)氣(qi)(qi)速(su)(su)率(lv)(lv)與(yu)氣(qi)(qi)體(ti)(ti)類型(xing)有(you)(you)關(guan)。給(gei)定的(de)(de)(de)(de)(de)(de)抽(chou)氣(qi)(qi)速(su)(su)率(lv)(lv)表示某(mou)種氣(qi)(qi)體(ti)(ti)的(de)(de)(de)(de)(de)(de)抽(chou)氣(qi)(qi)速(su)(su)率(lv)(lv)。如(ru)(ru)果(guo)沒有(you)(you)特殊指示，則使(shi)用(yong)多指抽(chou)吸。 正(zheng)確控(kong)制(zhi)(zhi)螺桿(gan)(gan)真(zhen)(zhen)空(kong)(kong)泵(beng)流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)不(bu)(bu)僅可以為設備提供良好(hao)的(de)(de)(de)(de)(de)(de)保護，還可以提高使(shi)用(yong)率(lv)(lv)。那么(me)，該(gai)怎么(me)做呢(ni)? 1，速(su)(su)度(du)(du)控(kong)制(zhi)(zhi) 葉輪(lun)速(su)(su)度(du)(du)的(de)(de)(de)(de)(de)(de)變(bian)化會改變(bian)螺桿(gan)(gan)真(zhen)(zhen)空(kong)(kong)泵(beng)的(de)(de)(de)(de)(de)(de)流(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)曲線(xian)，并且曲線(xian)的(de)(de)(de)(de)(de)(de)特性(xing)不(bu)(bu)會改變(bian)。隨著速(su)(su)度(du)(du)降(jiang)低(di)，曲線(xian)變(bian)平，揚程和流(liu)(liu)(liu)(liu)速(su)(su)降(jiang)低(di)。 2，旁(pang)通閥調整 使(shi)用(yong)與(yu)泵(beng)并聯的(de)(de)(de)(de)(de)(de)中間(jian)閥。實際(ji)效果(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，調整軸向間隙，以防止葉輪口環和軸向間隙不合適。使用時，請根據水環真空泵的出廠說明進行調整。注意要求，避免不當操作損壞設備 6.應及時清洗水環真空泵設備管路堵塞：異物殘留在進水管，葉輪或導流殼的流路中，會降低水環真空泵的?
