眾所(suo)周知，對于各種真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)性(xing)能(neng)，都有(you)(you)規定(ding)的(de)(de)(de)(de)(de)(de)(de)測(ce)(ce)試方法(fa)來測(ce)(ce)試該性(xing)能(neng)的(de)(de)(de)(de)(de)(de)(de)性(xing)能(neng)，主要性(xing)能(neng)是(shi)極限(xian)壓(ya)(ya)(ya)(ya)(ya)力(li)，流(liu)(liu)(liu)量(liang)(liang)(liang)和抽(chou)(chou)速(su)(su)(su)。這次，小編打算討論螺桿(gan)真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)(liang)，例如如何(he)(he)控(kong)制(zhi)其流(liu)(liu)(liu)量(liang)(liang)(liang)，流(liu)(liu)(liu)量(liang)(liang)(liang)不足的(de)(de)(de)(de)(de)(de)(de)原因以(yi)(yi)及如何(he)(he)消(xiao)除此問題(ti)。相信(xin)許(xu)多(duo)用戶對這些問題(ti)感到困惑，不用擔心，請跟隨(sui)螺桿(gan)真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)廠家進(jin)行了解。 首先，讓我們簡(jian)單介紹一下真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)主要性(xing)能(neng)的(de)(de)(de)(de)(de)(de)(de)概念。 1.極限(xian)壓(ya)(ya)(ya)(ya)(ya)力(li)。真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)與檢測(ce)(ce)容器相連，放置待測(ce)(ce)氣(qi)(qi)(qi)(qi)體(ti)后，連續(xu)長(chang)時間(jian)(jian)抽(chou)(chou)氣(qi)(qi)(qi)(qi)。當容器的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)壓(ya)(ya)(ya)(ya)(ya)不再降低并且壓(ya)(ya)(ya)(ya)(ya)力(li)保持在一定(ding)值時，次級(ji)壓(ya)(ya)(ya)(ya)(ya)力(li)就(jiu)是(shi)泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)極限(xian)壓(ya)(ya)(ya)(ya)(ya)力(li)。 2.流(liu)(liu)(liu)量(liang)(liang)(liang)。在真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)吸(xi)入(ru)口(kou)，每單位(wei)時間(jian)(jian)的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)流(liu)(liu)(liu)量(liang)(liang)(liang)稱為泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)(liang)。在真(zhen)(zhen)空(kong)(kong)技術中，流(liu)(liu)(liu)量(liang)(liang)(liang)單位(wei)以(yi)(yi)壓(ya)(ya)(ya)(ya)(ya)力(li)*體(ti)積/時間(jian)(jian)表示(shi)(shi)，即Pa.m3/s或Pa.m3/h。通(tong)常，泵(beng)(beng)會給出流(liu)(liu)(liu)量(liang)(liang)(liang)與入(ru)口(kou)壓(ya)(ya)(ya)(ya)(ya)力(li)的(de)(de)(de)(de)(de)(de)(de)關(guan)系圖。 3.抽(chou)(chou)速(su)(su)(su)。在真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)吸(xi)入(ru)口(kou)，每單位(wei)時間(jian)(jian)流(liu)(liu)(liu)動的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)量(liang)(liang)(liang)稱為泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)抽(chou)(chou)氣(qi)(qi)(qi)(qi)速(su)(su)(su)率。即，通(tong)過將流(liu)(liu)(liu)量(liang)(liang)(liang)QA(Pa.m3/s)除以(yi)(yi)測(ce)(ce)試罩中的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)A的(de)(de)(de)(de)(de)(de)(de)分壓(ya)(ya)(ya)(ya)(ya)pA而獲得(de)氣(qi)(qi)(qi)(qi)體(ti)A的(de)(de)(de)(de)(de)(de)(de)泵(beng)(beng)送速(su)(su)(su)度(du)sA(m3/s)。典型的(de)(de)(de)(de)(de)(de)(de)真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)抽(chou)(chou)氣(qi)(qi)(qi)(qi)速(su)(su)(su)率與氣(qi)(qi)(qi)(qi)體(ti)類型有(you)(you)關(guan)。給定(ding)的(de)(de)(de)(de)(de)(de)(de)抽(chou)(chou)氣(qi)(qi)(qi)(qi)速(su)(su)(su)率表示(shi)(shi)某種氣(qi)(qi)(qi)(qi)體(ti)的(de)(de)(de)(de)(de)(de)(de)抽(chou)(chou)氣(qi)(qi)(qi)(qi)速(su)(su)(su)率。如果(guo)沒有(you)(you)特(te)殊指示(shi)(shi)，則使(shi)用多(duo)指抽(chou)(chou)吸(xi)。 正確控(kong)制(zhi)螺桿(gan)真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)流(liu)(liu)(liu)量(liang)(liang)(liang)不僅可(ke)以(yi)(yi)為設備提供良(liang)好的(de)(de)(de)(de)(de)(de)(de)保護(hu)，還可(ke)以(yi)(yi)提高使(shi)用率。那么(me)，該怎(zen)么(me)做(zuo)呢? 1，速(su)(su)(su)度(du)控(kong)制(zhi) 葉輪速(su)(su)(su)度(du)的(de)(de)(de)(de)(de)(de)(de)變(bian)化會改變(bian)螺桿(gan)真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)(de)(de)(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)(liang)曲(qu)(qu)(qu)線，并且曲(qu)(qu)(qu)線的(de)(de)(de)(de)(de)(de)(de)特(te)性(xing)不會改變(bian)。隨(sui)著速(su)(su)(su)度(du)降低，曲(qu)(qu)(qu)線變(bian)平，揚程和流(liu)(liu)(liu)速(su)(su)(su)降低。 2，旁通(tong)閥調整 使(shi)用與泵(beng)(beng)并聯的(de)(de)(de)(de)(de)(de)(de)中間(jian)(jian)閥。實際效(xiao)果(guo)就(jiu)...

離(li)心泵有(you)很多不同的(de)(de)類(lei)型，對于不同液(ye)(ye)體(ti)需要(yao)(yao)選(xuan)(xuan)擇(ze)(ze)(ze)不同的(de)(de)離(li)心泵，液(ye)(ye)體(ti)粘(zhan)度(du)不大(da)、流量(liang)(liang)較大(da)、揚(yang)程不高時(shi)，宜選(xuan)(xuan)用(yong)(yong)往(wang)復(fu)泵；液(ye)(ye)體(ti)粘(zhan)度(du)較大(da)、流量(liang)(liang)較小、揚(yang)程不高或含有(you)氣泡(pao)時(shi)，可選(xuan)(xuan)用(yong)(yong)旋渦泵；液(ye)(ye)體(ti)粘(zhan)度(du)較大(da)、流量(liang)(liang)較小、揚(yang)程較高時(shi)，宜選(xuan)(xuan)用(yong)(yong)轉子(zi)泵。 理(li)解類(lei)型的(de)(de)選(xuan)(xuan)擇(ze)(ze)(ze)是最基本(ben)的(de)(de)，只有(you)正確選(xuan)(xuan)擇(ze)(ze)(ze)才能(neng)使得正常運轉，但是我(wo)們在使用(yong)(yong)中經常會(hui)遇到突然(ran)泄漏(lou)的(de)(de)問題，這又是哪(na)些原(yuan)因造成的(de)(de)呢？下(xia)面就來分析一(yi)(yi)下(xia)。 1、抽(chou)空(kong)、氣蝕(shi)或較長時(shi)間憋壓，導(dao)致密(mi)封破壞； 2、對泵實際輸出量(liang)(liang)偏小，大(da)量(liang)(liang)介質(zhi)泵內循環(huan)，熱量(liang)(liang)積聚(ju)，引起(qi)介質(zhi)氣化(hua)，導(dao)致密(mi)封失效； 3、回流量(liang)(liang)偏大(da)，導(dao)致吸(xi)人管側容(rong)器(塔、釜、罐、池)底(di)部沉渣泛(fan)起(qi)，損壞密(mi)封； 4、對較長時(shi)間停運，重新(xin)起(qi)動時(shi)沒有(you)手動盤車，摩擦副(fu)因粘(zhan)連(lian)而扯壞密(mi)封面； 5、介質(zhi)中腐蝕(shi)性、聚(ju)合(he)性、結膠性物質(zhi)增多； 6、環(huan)境溫度(du)急劇變化(hua)； 7、工況頻(pin)繁變化(hua)或調(diao)整； 8、突然(ran)停電或故障停機等。 當遇到突然(ran)泄漏(lou)的(de)(de)問題，我(wo)們一(yi)(yi)定要(yao)(yao)正確分析，以采取(qu)對的(de)(de)措施，以免造成不要(yao)(yao)的(de)(de)損失。

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?
