眾所周知，對于各種真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)性(xing)(xing)(xing)能(neng)，都有規定(ding)的(de)(de)(de)(de)(de)測試(shi)方法來測試(shi)該性(xing)(xing)(xing)能(neng)的(de)(de)(de)(de)(de)性(xing)(xing)(xing)能(neng)，主要性(xing)(xing)(xing)能(neng)是極(ji)(ji)限(xian)(xian)壓(ya)(ya)(ya)力(li)(li)，流(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)和抽(chou)速(su)。這次(ci)，小編打(da)算討論螺桿真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)流(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)，例如(ru)如(ru)何控(kong)制其流(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)，流(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)不足的(de)(de)(de)(de)(de)原因以(yi)(yi)及如(ru)何消除此問題。相信許多(duo)(duo)用(yong)(yong)戶對這些問題感到困惑，不用(yong)(yong)擔(dan)心，請跟隨螺桿真(zhen)空(kong)(kong)泵(beng)(beng)(beng)廠家進行了解。 首先，讓我們簡單(dan)(dan)介(jie)紹(shao)一下真(zhen)空(kong)(kong)泵(beng)(beng)(beng)主要性(xing)(xing)(xing)能(neng)的(de)(de)(de)(de)(de)概念(nian)。 1.極(ji)(ji)限(xian)(xian)壓(ya)(ya)(ya)力(li)(li)。真(zhen)空(kong)(kong)泵(beng)(beng)(beng)與檢測容(rong)器(qi)相連，放置(zhi)待(dai)測氣(qi)體(ti)后，連續長時(shi)間抽(chou)氣(qi)。當(dang)容(rong)器(qi)的(de)(de)(de)(de)(de)氣(qi)壓(ya)(ya)(ya)不再降低(di)(di)并且壓(ya)(ya)(ya)力(li)(li)保(bao)持在(zai)一定(ding)值時(shi)，次(ci)級(ji)壓(ya)(ya)(ya)力(li)(li)就(jiu)是泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)極(ji)(ji)限(xian)(xian)壓(ya)(ya)(ya)力(li)(li)。 2.流(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)。在(zai)真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)吸(xi)入口，每(mei)單(dan)(dan)位(wei)時(shi)間的(de)(de)(de)(de)(de)氣(qi)體(ti)流(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)稱為泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)流(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)。在(zai)真(zhen)空(kong)(kong)技術(shu)中，流(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)單(dan)(dan)位(wei)以(yi)(yi)壓(ya)(ya)(ya)力(li)(li)*體(ti)積/時(shi)間表示(shi)(shi)，即(ji)Pa.m3/s或Pa.m3/h。通常，泵(beng)(beng)(beng)會給(gei)(gei)出流(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)與入口壓(ya)(ya)(ya)力(li)(li)的(de)(de)(de)(de)(de)關系圖。 3.抽(chou)速(su)。在(zai)真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)吸(xi)入口，每(mei)單(dan)(dan)位(wei)時(shi)間流(liu)(liu)(liu)(liu)(liu)動的(de)(de)(de)(de)(de)氣(qi)體(ti)量(liang)(liang)(liang)(liang)(liang)稱為泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)抽(chou)氣(qi)速(su)率。即(ji)，通過將流(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)QA(Pa.m3/s)除以(yi)(yi)測試(shi)罩中的(de)(de)(de)(de)(de)氣(qi)體(ti)A的(de)(de)(de)(de)(de)分壓(ya)(ya)(ya)pA而獲得氣(qi)體(ti)A的(de)(de)(de)(de)(de)泵(beng)(beng)(beng)送速(su)度(du)sA(m3/s)。典型(xing)的(de)(de)(de)(de)(de)真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)抽(chou)氣(qi)速(su)率與氣(qi)體(ti)類型(xing)有關。給(gei)(gei)定(ding)的(de)(de)(de)(de)(de)抽(chou)氣(qi)速(su)率表示(shi)(shi)某種氣(qi)體(ti)的(de)(de)(de)(de)(de)抽(chou)氣(qi)速(su)率。如(ru)果沒(mei)有特殊(shu)指(zhi)示(shi)(shi)，則使用(yong)(yong)多(duo)(duo)指(zhi)抽(chou)吸(xi)。 正確控(kong)制螺桿真(zhen)空(kong)(kong)泵(beng)(beng)(beng)流(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)不僅可以(yi)(yi)為設(she)備提(ti)供(gong)良好(hao)的(de)(de)(de)(de)(de)保(bao)護，還(huan)可以(yi)(yi)提(ti)高使用(yong)(yong)率。那么，該怎么做呢? 1，速(su)度(du)控(kong)制 葉輪速(su)度(du)的(de)(de)(de)(de)(de)變(bian)(bian)化會改變(bian)(bian)螺桿真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)流(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)(liang)曲(qu)(qu)線(xian)，并且曲(qu)(qu)線(xian)的(de)(de)(de)(de)(de)特性(xing)(xing)(xing)不會改變(bian)(bian)。隨著速(su)度(du)降低(di)(di)，曲(qu)(qu)線(xian)變(bian)(bian)平，揚程和流(liu)(liu)(liu)(liu)(liu)速(su)降低(di)(di)。 2，旁通閥調整 使用(yong)(yong)與泵(beng)(beng)(beng)并聯(lian)的(de)(de)(de)(de)(de)中間閥。實際效果就(jiu)...

離心(xin)(xin)泵(beng)(beng)(beng)有很多不(bu)同的(de)(de)(de)類(lei)型，對于不(bu)同液(ye)體需要(yao)選(xuan)擇(ze)不(bu)同的(de)(de)(de)離心(xin)(xin)泵(beng)(beng)(beng)，液(ye)體粘度不(bu)大(da)(da)、流量較(jiao)大(da)(da)、揚(yang)程(cheng)不(bu)高時(shi)，宜選(xuan)用(yong)往復泵(beng)(beng)(beng)；液(ye)體粘度較(jiao)大(da)(da)、流量較(jiao)小(xiao)(xiao)、揚(yang)程(cheng)不(bu)高或含(han)有氣泡時(shi)，可選(xuan)用(yong)旋渦泵(beng)(beng)(beng)；液(ye)體粘度較(jiao)大(da)(da)、流量較(jiao)小(xiao)(xiao)、揚(yang)程(cheng)較(jiao)高時(shi)，宜選(xuan)用(yong)轉(zhuan)子泵(beng)(beng)(beng)。 理(li)解(jie)類(lei)型的(de)(de)(de)選(xuan)擇(ze)是(shi)最基本的(de)(de)(de)，只有正確選(xuan)擇(ze)才能(neng)使(shi)(shi)得正常(chang)運(yun)(yun)轉(zhuan)，但(dan)是(shi)我(wo)們在使(shi)(shi)用(yong)中經常(chang)會(hui)遇到突然泄(xie)漏的(de)(de)(de)問題，這又是(shi)哪些(xie)原因造(zao)成的(de)(de)(de)呢？下(xia)面(mian)就來分析一下(xia)。 1、抽空(kong)、氣蝕或較(jiao)長時(shi)間憋壓，導(dao)致密封(feng)破壞； 2、對泵(beng)(beng)(beng)實際輸出量偏小(xiao)(xiao)，大(da)(da)量介(jie)質(zhi)泵(beng)(beng)(beng)內循環(huan)，熱(re)量積聚(ju)，引起介(jie)質(zhi)氣化，導(dao)致密封(feng)失(shi)效(xiao)； 3、回流量偏大(da)(da)，導(dao)致吸人管側容器(塔、釜、罐(guan)、池(chi))底部沉渣泛(fan)起，損(sun)壞密封(feng)； 4、對較(jiao)長時(shi)間停運(yun)(yun)，重新起動時(shi)沒有手動盤車，摩擦副因粘連而扯(che)壞密封(feng)面(mian)； 5、介(jie)質(zhi)中腐蝕性(xing)、聚(ju)合性(xing)、結(jie)膠性(xing)物(wu)質(zhi)增多； 6、環(huan)境溫度急劇變化； 7、工況(kuang)頻繁變化或調整； 8、突然停電或故(gu)障停機等。 當遇到突然泄(xie)漏的(de)(de)(de)問題，我(wo)們一定要(yao)正確分析，以采取對的(de)(de)(de)措施，以免(mian)造(zao)成不(bu)要(yao)的(de)(de)(de)損(sun)失(shi)。

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?
