眾所周(zhou)知，對于各種真(zhen)(zhen)空(kong)泵(beng)(beng)的(de)(de)性(xing)能(neng)(neng)，都有(you)規(gui)定的(de)(de)測試方法(fa)來(lai)測試該性(xing)能(neng)(neng)的(de)(de)性(xing)能(neng)(neng)，主要性(xing)能(neng)(neng)是極限(xian)壓(ya)力(li)，流(liu)(liu)量(liang)(liang)(liang)和(he)(he)抽速(su)(su)(su)(su)。這次(ci)，小編打算討論螺(luo)桿(gan)真(zhen)(zhen)空(kong)泵(beng)(beng)的(de)(de)流(liu)(liu)量(liang)(liang)(liang)，例如如何控制其流(liu)(liu)量(liang)(liang)(liang)，流(liu)(liu)量(liang)(liang)(liang)不(bu)足的(de)(de)原因以及如何消除(chu)此(ci)問(wen)題。相(xiang)信許多用戶對這些問(wen)題感(gan)到(dao)困(kun)惑(huo)，不(bu)用擔(dan)心(xin)，請跟(gen)隨螺(luo)桿(gan)真(zhen)(zhen)空(kong)泵(beng)(beng)廠家進行(xing)了解。 首先，讓我們簡單(dan)(dan)介紹一(yi)下(xia)真(zhen)(zhen)空(kong)泵(beng)(beng)主要性(xing)能(neng)(neng)的(de)(de)概念。 1.極限(xian)壓(ya)力(li)。真(zhen)(zhen)空(kong)泵(beng)(beng)與檢(jian)測容器(qi)相(xiang)連，放置待測氣(qi)(qi)(qi)體(ti)后，連續長時(shi)(shi)間(jian)抽氣(qi)(qi)(qi)。當容器(qi)的(de)(de)氣(qi)(qi)(qi)壓(ya)不(bu)再(zai)降低(di)并且(qie)壓(ya)力(li)保(bao)持在一(yi)定值時(shi)(shi)，次(ci)級壓(ya)力(li)就(jiu)是泵(beng)(beng)的(de)(de)極限(xian)壓(ya)力(li)。 2.流(liu)(liu)量(liang)(liang)(liang)。在真(zhen)(zhen)空(kong)泵(beng)(beng)的(de)(de)吸入(ru)(ru)口，每單(dan)(dan)位(wei)時(shi)(shi)間(jian)的(de)(de)氣(qi)(qi)(qi)體(ti)流(liu)(liu)量(liang)(liang)(liang)稱為泵(beng)(beng)的(de)(de)流(liu)(liu)量(liang)(liang)(liang)。在真(zhen)(zhen)空(kong)技術(shu)中(zhong)(zhong)(zhong)，流(liu)(liu)量(liang)(liang)(liang)單(dan)(dan)位(wei)以壓(ya)力(li)*體(ti)積/時(shi)(shi)間(jian)表(biao)示，即Pa.m3/s或Pa.m3/h。通(tong)(tong)常，泵(beng)(beng)會給出流(liu)(liu)量(liang)(liang)(liang)與入(ru)(ru)口壓(ya)力(li)的(de)(de)關(guan)系圖。 3.抽速(su)(su)(su)(su)。在真(zhen)(zhen)空(kong)泵(beng)(beng)的(de)(de)吸入(ru)(ru)口，每單(dan)(dan)位(wei)時(shi)(shi)間(jian)流(liu)(liu)動的(de)(de)氣(qi)(qi)(qi)體(ti)量(liang)(liang)(liang)稱為泵(beng)(beng)的(de)(de)抽氣(qi)(qi)(qi)速(su)(su)(su)(su)率(lv)。即，通(tong)(tong)過將流(liu)(liu)量(liang)(liang)(liang)QA(Pa.m3/s)除(chu)以測試罩中(zhong)(zhong)(zhong)的(de)(de)氣(qi)(qi)(qi)體(ti)A的(de)(de)分(fen)壓(ya)pA而獲得氣(qi)(qi)(qi)體(ti)A的(de)(de)泵(beng)(beng)送(song)速(su)(su)(su)(su)度(du)sA(m3/s)。典型(xing)的(de)(de)真(zhen)(zhen)空(kong)泵(beng)(beng)的(de)(de)抽氣(qi)(qi)(qi)速(su)(su)(su)(su)率(lv)與氣(qi)(qi)(qi)體(ti)類(lei)型(xing)有(you)關(guan)。給定的(de)(de)抽氣(qi)(qi)(qi)速(su)(su)(su)(su)率(lv)表(biao)示某種氣(qi)(qi)(qi)體(ti)的(de)(de)抽氣(qi)(qi)(qi)速(su)(su)(su)(su)率(lv)。如果(guo)沒有(you)特(te)殊指示，則(ze)使(shi)(shi)(shi)用多指抽吸。 正確控制螺(luo)桿(gan)真(zhen)(zhen)空(kong)泵(beng)(beng)流(liu)(liu)量(liang)(liang)(liang)不(bu)僅可(ke)以為設備提(ti)供(gong)良好的(de)(de)保(bao)護，還可(ke)以提(ti)高使(shi)(shi)(shi)用率(lv)。那么，該怎么做呢? 1，速(su)(su)(su)(su)度(du)控制 葉輪速(su)(su)(su)(su)度(du)的(de)(de)變化會改變螺(luo)桿(gan)真(zhen)(zhen)空(kong)泵(beng)(beng)的(de)(de)流(liu)(liu)量(liang)(liang)(liang)曲線(xian)，并且(qie)曲線(xian)的(de)(de)特(te)性(xing)不(bu)會改變。隨著速(su)(su)(su)(su)度(du)降低(di)，曲線(xian)變平，揚程和(he)(he)流(liu)(liu)速(su)(su)(su)(su)降低(di)。 2，旁通(tong)(tong)閥(fa)調整 使(shi)(shi)(shi)用與泵(beng)(beng)并聯的(de)(de)中(zhong)(zhong)(zhong)間(jian)閥(fa)。實際(ji)效果(guo)就(jiu)...

離心泵(beng)(beng)(beng)有(you)很(hen)多不(bu)(bu)(bu)同的(de)類型(xing)，對(dui)于不(bu)(bu)(bu)同液(ye)(ye)體(ti)需要選(xuan)擇(ze)不(bu)(bu)(bu)同的(de)離心泵(beng)(beng)(beng)，液(ye)(ye)體(ti)粘(zhan)度(du)不(bu)(bu)(bu)大(da)(da)、流量較(jiao)(jiao)大(da)(da)、揚程(cheng)(cheng)不(bu)(bu)(bu)高(gao)時(shi)，宜選(xuan)用往(wang)復(fu)泵(beng)(beng)(beng)；液(ye)(ye)體(ti)粘(zhan)度(du)較(jiao)(jiao)大(da)(da)、流量較(jiao)(jiao)小(xiao)(xiao)、揚程(cheng)(cheng)不(bu)(bu)(bu)高(gao)或含有(you)氣(qi)泡時(shi)，可選(xuan)用旋渦泵(beng)(beng)(beng)；液(ye)(ye)體(ti)粘(zhan)度(du)較(jiao)(jiao)大(da)(da)、流量較(jiao)(jiao)小(xiao)(xiao)、揚程(cheng)(cheng)較(jiao)(jiao)高(gao)時(shi)，宜選(xuan)用轉子泵(beng)(beng)(beng)。 理解類型(xing)的(de)選(xuan)擇(ze)是(shi)最基本的(de)，只有(you)正(zheng)確選(xuan)擇(ze)才能使得正(zheng)常運(yun)轉，但(dan)是(shi)我們在使用中經(jing)常會遇(yu)(yu)到突然泄(xie)漏的(de)問題，這(zhe)又是(shi)哪些原因造成的(de)呢？下面就來(lai)分析一下。 1、抽空、氣(qi)蝕(shi)或較(jiao)(jiao)長時(shi)間憋壓，導(dao)致密(mi)(mi)封(feng)破壞； 2、對(dui)泵(beng)(beng)(beng)實際輸出(chu)量偏(pian)小(xiao)(xiao)，大(da)(da)量介(jie)質泵(beng)(beng)(beng)內循環，熱量積聚，引(yin)起(qi)介(jie)質氣(qi)化，導(dao)致密(mi)(mi)封(feng)失效(xiao)； 3、回流量偏(pian)大(da)(da)，導(dao)致吸人管側容器(塔、釜、罐、池)底部(bu)沉渣泛起(qi)，損壞密(mi)(mi)封(feng)； 4、對(dui)較(jiao)(jiao)長時(shi)間停運(yun)，重新起(qi)動時(shi)沒有(you)手動盤車(che)，摩擦(ca)副(fu)因粘(zhan)連而扯(che)壞密(mi)(mi)封(feng)面； 5、介(jie)質中腐(fu)蝕(shi)性、聚合性、結膠性物(wu)質增多； 6、環境溫度(du)急劇變(bian)化； 7、工況(kuang)頻繁變(bian)化或調整； 8、突然停電或故(gu)障停機等(deng)。 當(dang)遇(yu)(yu)到突然泄(xie)漏的(de)問題，我們一定(ding)要正(zheng)確分析，以(yi)采(cai)取對(dui)的(de)措施，以(yi)免(mian)造成不(bu)(bu)(bu)要的(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
