眾所周(zhou)知，對(dui)于各種(zhong)真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)性(xing)能(neng)，都(dou)有規(gui)定(ding)(ding)的(de)(de)(de)(de)測試方法來測試該性(xing)能(neng)的(de)(de)(de)(de)性(xing)能(neng)，主要(yao)性(xing)能(neng)是極(ji)(ji)限(xian)壓(ya)(ya)力，流(liu)(liu)(liu)量(liang)(liang)和抽(chou)(chou)(chou)速(su)(su)(su)。這次，小編打算討論(lun)螺桿(gan)(gan)真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)，例如(ru)如(ru)何(he)控(kong)(kong)制(zhi)其流(liu)(liu)(liu)量(liang)(liang)，流(liu)(liu)(liu)量(liang)(liang)不(bu)足的(de)(de)(de)(de)原因以及如(ru)何(he)消除此問題。相信許多(duo)(duo)用戶對(dui)這些問題感到困惑，不(bu)用擔心，請(qing)跟隨(sui)螺桿(gan)(gan)真(zhen)空(kong)(kong)泵(beng)(beng)(beng)廠(chang)家進(jin)行了(le)解。 首先，讓我(wo)們簡(jian)單介(jie)紹一下真(zhen)空(kong)(kong)泵(beng)(beng)(beng)主要(yao)性(xing)能(neng)的(de)(de)(de)(de)概念。 1.極(ji)(ji)限(xian)壓(ya)(ya)力。真(zhen)空(kong)(kong)泵(beng)(beng)(beng)與(yu)檢測容(rong)器相連，放置(zhi)待測氣(qi)(qi)(qi)體(ti)(ti)后，連續(xu)長時(shi)(shi)間抽(chou)(chou)(chou)氣(qi)(qi)(qi)。當容(rong)器的(de)(de)(de)(de)氣(qi)(qi)(qi)壓(ya)(ya)不(bu)再降(jiang)(jiang)低并且壓(ya)(ya)力保(bao)持在(zai)一定(ding)(ding)值(zhi)時(shi)(shi)，次級壓(ya)(ya)力就(jiu)是泵(beng)(beng)(beng)的(de)(de)(de)(de)極(ji)(ji)限(xian)壓(ya)(ya)力。 2.流(liu)(liu)(liu)量(liang)(liang)。在(zai)真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)吸入口，每單位時(shi)(shi)間的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)流(liu)(liu)(liu)量(liang)(liang)稱為(wei)泵(beng)(beng)(beng)的(de)(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)。在(zai)真(zhen)空(kong)(kong)技術中，流(liu)(liu)(liu)量(liang)(liang)單位以壓(ya)(ya)力*體(ti)(ti)積/時(shi)(shi)間表(biao)示，即(ji)Pa.m3/s或(huo)Pa.m3/h。通常(chang)，泵(beng)(beng)(beng)會給出流(liu)(liu)(liu)量(liang)(liang)與(yu)入口壓(ya)(ya)力的(de)(de)(de)(de)關(guan)系(xi)圖。 3.抽(chou)(chou)(chou)速(su)(su)(su)。在(zai)真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)吸入口，每單位時(shi)(shi)間流(liu)(liu)(liu)動的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)量(liang)(liang)稱為(wei)泵(beng)(beng)(beng)的(de)(de)(de)(de)抽(chou)(chou)(chou)氣(qi)(qi)(qi)速(su)(su)(su)率。即(ji)，通過(guo)將流(liu)(liu)(liu)量(liang)(liang)QA(Pa.m3/s)除以測試罩中的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)A的(de)(de)(de)(de)分壓(ya)(ya)pA而獲得(de)氣(qi)(qi)(qi)體(ti)(ti)A的(de)(de)(de)(de)泵(beng)(beng)(beng)送速(su)(su)(su)度sA(m3/s)。典型(xing)的(de)(de)(de)(de)真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)抽(chou)(chou)(chou)氣(qi)(qi)(qi)速(su)(su)(su)率與(yu)氣(qi)(qi)(qi)體(ti)(ti)類型(xing)有關(guan)。給定(ding)(ding)的(de)(de)(de)(de)抽(chou)(chou)(chou)氣(qi)(qi)(qi)速(su)(su)(su)率表(biao)示某種(zhong)氣(qi)(qi)(qi)體(ti)(ti)的(de)(de)(de)(de)抽(chou)(chou)(chou)氣(qi)(qi)(qi)速(su)(su)(su)率。如(ru)果沒(mei)有特殊指示，則使用多(duo)(duo)指抽(chou)(chou)(chou)吸。 正確(que)控(kong)(kong)制(zhi)螺桿(gan)(gan)真(zhen)空(kong)(kong)泵(beng)(beng)(beng)流(liu)(liu)(liu)量(liang)(liang)不(bu)僅可(ke)以為(wei)設備提供良好(hao)的(de)(de)(de)(de)保(bao)護，還可(ke)以提高使用率。那么(me)，該怎么(me)做呢? 1，速(su)(su)(su)度控(kong)(kong)制(zhi) 葉輪速(su)(su)(su)度的(de)(de)(de)(de)變(bian)化會改變(bian)螺桿(gan)(gan)真(zhen)空(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)流(liu)(liu)(liu)量(liang)(liang)曲線，并且曲線的(de)(de)(de)(de)特性(xing)不(bu)會改變(bian)。隨(sui)著速(su)(su)(su)度降(jiang)(jiang)低，曲線變(bian)平，揚程和流(liu)(liu)(liu)速(su)(su)(su)降(jiang)(jiang)低。 2，旁(pang)通閥調整 使用與(yu)泵(beng)(beng)(beng)并聯的(de)(de)(de)(de)中間閥。實(shi)際效(xiao)果就(jiu)...

為(wei)化工(gong)與制(zhi)藥(yao)工(gong)藝(yi)應用(yong)(yong)選擇合適的(de)真(zhen)(zhen)(zhen)空(kong)技術往往并非(fei)易事。首(shou)先(xian)，真(zhen)(zhen)(zhen)空(kong)系(xi)統(tong)必須(xu)在工(gong)作(zuo)(zuo)壓(ya)力下提供所(suo)需(xu)泵(beng)(beng)(beng)(beng)速(su)，確保所(suo)需(xu)抽真(zhen)(zhen)(zhen)空(kong)時(shi)(shi)間(jian)(jian)。其次，它不能對工(gong)藝(yi)氣(qi)(qi)(qi)體(ti)(ti)(ti)敏感(gan)，在用(yong)(yong)于(yu)(yu)(yu) CIP(在位清(qing)洗)清(qing)洗和氣(qi)(qi)(qi)體(ti)(ti)(ti)回(hui)收時(shi)(shi)必須(xu)滿足所(suo)有(you)(you)要(yao)求(qiu)。此外，在確定要(yao)使用(yong)(yong)哪種(zhong)(zhong)(zhong)真(zhen)(zhen)(zhen)空(kong)技術時(shi)(shi)，穩定性和經濟效(xiao)率(lv)也起著重要(yao)作(zuo)(zuo)用(yong)(yong)。 在本文中(zhong)，我(wo)們(men)將講述化工(gong)與制(zhi)藥(yao)加工(gong)技術中(zhong)最常用(yong)(yong)的(de)三(san)種(zhong)(zhong)(zhong)真(zhen)(zhen)(zhen)空(kong)技術。 水(shui)(shui)(shui)(shui)環真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng), 干式螺桿真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng), 油(you)(you)潤滑旋片真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)。 水(shui)(shui)(shui)(shui)環真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng) 水(shui)(shui)(shui)(shui)環真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)適用(yong)(yong)于(yu)(yu)(yu)多(duo)(duo)種(zhong)(zhong)(zhong)應用(yong)(yong)。它們(men)屬于(yu)(yu)(yu)旋轉(zhuan)正排(pai)量泵(beng)(beng)(beng)(beng)，葉(xie)輪偏心(xin)(xin)放置在圓柱形(xing)外殼(ke)中(zhong)(圖 2)。一般用(yong)(yong)水(shui)(shui)(shui)(shui)充當工(gong)作(zuo)(zuo)液。葉(xie)輪旋轉(zhuan)時(shi)(shi)，會(hui)在密封各葉(xie)片空(kong)間(jian)(jian)的(de)外殼(ke)內形(xing)成(cheng)水(shui)(shui)(shui)(shui)環。氣(qi)(qi)(qi)體(ti)(ti)(ti)在中(zhong)心(xin)(xin)、各葉(xie)片和液體(ti)(ti)(ti)環間(jian)(jian)形(xing)成(cheng)的(de)空(kong)間(jian)(jian)中(zhong)輸送。由于(yu)(yu)(yu)葉(xie)輪安裝(zhuang)于(yu)(yu)(yu)偏心(xin)(xin)位置，這部分(fen)空(kong)間(jian)(jian)的(de)體(ti)(ti)(ti)積會(hui)增(zeng)大(da)，從而經進氣(qi)(qi)(qi)口吸入介(jie)(jie)質(zhi)。當葉(xie)輪繼續(xu)旋轉(zhuan)時(shi)(shi)，空(kong)間(jian)(jian)體(ti)(ti)(ti)積減少，氣(qi)(qi)(qi)體(ti)(ti)(ti)介(jie)(jie)質(zhi)被壓(ya)縮，然(ran)后通過排(pai)氣(qi)(qi)(qi)口被再次排(pai)出。水(shui)(shui)(shui)(shui)環真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)既可作(zuo)(zuo)為(wei)單一的(de)連續(xu)流系(xi)統(tong)運行(xing)，也可作(zuo)(zuo)為(wei)部分(fen)或(huo)(huo)(huo)全循環系(xi)統(tong)運行(xing)。 多(duo)(duo)年來，經實踐證明，這些真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)在化學工(gong)藝(yi)中(zhong)是堅固耐用(yong)(yong)、質(zhi)量可靠的(de)真(zhen)(zhen)(zhen)空(kong)發生器。壓(ya)縮室內的(de)工(gong)作(zuo)(zuo)液不斷耗(hao)散(san)壓(ya)縮熱，因此真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)的(de)運行(xing)幾(ji)乎是等溫(wen)(wen)的(de)。這意味著工(gong)藝(yi)氣(qi)(qi)(qi)體(ti)(ti)(ti)不會(hui)明顯升(sheng)溫(wen)(wen)，真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)在相(xiang)對較低的(de)溫(wen)(wen)度下運行(xing)。這將顯著降低不必要(yao)的(de)反(fan)應或(huo)(huo)(huo)爆炸的(de)風險。低工(gong)作(zuo)(zuo)溫(wen)(wen)度還有(you)(you)利于(yu)(yu)(yu)蒸汽(qi)和氣(qi)(qi)(qi)體(ti)(ti)(ti)的(de)冷凝(ning)，提升(sheng)真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)的(de)額定泵(beng)(beng)(beng)(beng)速(su)。 一般用(yong)(yong)水(shui)(shui)(shui)(shui)來作(zuo)(zuo)為(wei)水(shui)(shui)(shui)(shui)環。在實際(ji)應用(yong)(yong)中(zhong)，還經常使用(yong)(yong)乙二(er)醇、礦物油(you)(you)或(huo)(huo)(huo)有(you)(you)機溶(rong)劑。真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)的(de)極...

離(li)心(xin)(xin)泵(beng)(beng)有(you)很多不同(tong)的(de)(de)類型，對于不同(tong)液(ye)(ye)體(ti)(ti)需要選擇(ze)(ze)不同(tong)的(de)(de)離(li)心(xin)(xin)泵(beng)(beng)，液(ye)(ye)體(ti)(ti)粘度不大(da)(da)、流(liu)量(liang)較(jiao)(jiao)大(da)(da)、揚(yang)程(cheng)不高時(shi)，宜選用(yong)往復泵(beng)(beng)；液(ye)(ye)體(ti)(ti)粘度較(jiao)(jiao)大(da)(da)、流(liu)量(liang)較(jiao)(jiao)小(xiao)、揚(yang)程(cheng)不高或(huo)(huo)含有(you)氣(qi)泡時(shi)，可選用(yong)旋渦泵(beng)(beng)；液(ye)(ye)體(ti)(ti)粘度較(jiao)(jiao)大(da)(da)、流(liu)量(liang)較(jiao)(jiao)小(xiao)、揚(yang)程(cheng)較(jiao)(jiao)高時(shi)，宜選用(yong)轉(zhuan)子泵(beng)(beng)。 理解類型的(de)(de)選擇(ze)(ze)是(shi)最基本的(de)(de)，只(zhi)有(you)正確選擇(ze)(ze)才能使得正常運轉(zhuan)，但是(shi)我(wo)們(men)在(zai)使用(yong)中(zhong)經常會遇到(dao)突(tu)然泄漏(lou)的(de)(de)問題，這又是(shi)哪些原因造成(cheng)的(de)(de)呢？下(xia)面(mian)就(jiu)來分析一(yi)下(xia)。 1、抽空、氣(qi)蝕或(huo)(huo)較(jiao)(jiao)長時(shi)間(jian)憋壓，導致密(mi)封破(po)壞(huai)(huai)； 2、對泵(beng)(beng)實際輸(shu)出量(liang)偏(pian)小(xiao)，大(da)(da)量(liang)介(jie)質泵(beng)(beng)內循(xun)環(huan)，熱(re)量(liang)積(ji)聚，引起(qi)(qi)介(jie)質氣(qi)化(hua)(hua)，導致密(mi)封失效(xiao)； 3、回流(liu)量(liang)偏(pian)大(da)(da)，導致吸人(ren)管側容器(塔、釜、罐、池(chi))底(di)部沉渣泛起(qi)(qi)，損壞(huai)(huai)密(mi)封； 4、對較(jiao)(jiao)長時(shi)間(jian)停(ting)運，重(zhong)新起(qi)(qi)動(dong)時(shi)沒(mei)有(you)手(shou)動(dong)盤(pan)車(che)，摩(mo)擦副因粘連而(er)扯壞(huai)(huai)密(mi)封面(mian)； 5、介(jie)質中(zhong)腐蝕性(xing)、聚合性(xing)、結(jie)膠性(xing)物質增多； 6、環(huan)境溫度急(ji)劇變化(hua)(hua)； 7、工況頻繁(fan)變化(hua)(hua)或(huo)(huo)調整(zheng)； 8、突(tu)然停(ting)電或(huo)(huo)故障停(ting)機(ji)等。 當(dang)遇到(dao)突(tu)然泄漏(lou)的(de)(de)問題，我(wo)們(men)一(yi)定要正確分析，以采取對的(de)(de)措施，以免造成(cheng)不要的(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泵?
