為化工(gong)(gong)與制藥(yao)工(gong)(gong)藝應用(yong)(yong)(yong)(yong)(yong)選擇合適的(de)(de)(de)(de)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)技術(shu)往往并非易(yi)事。首先，真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)系(xi)統必須(xu)在(zai)工(gong)(gong)作(zuo)壓力(li)下提供所需泵(beng)(beng)(beng)速，確保所需抽真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)時(shi)(shi)間。其次，它(ta)不能對工(gong)(gong)藝氣(qi)(qi)體(ti)(ti)(ti)敏感(gan)，在(zai)用(yong)(yong)(yong)(yong)(yong)于(yu) CIP(在(zai)位清(qing)洗(xi))清(qing)洗(xi)和氣(qi)(qi)體(ti)(ti)(ti)回收時(shi)(shi)必須(xu)滿(man)足所有要求。此外(wai)，在(zai)確定(ding)(ding)要使用(yong)(yong)(yong)(yong)(yong)哪種真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)技術(shu)時(shi)(shi)，穩定(ding)(ding)性和經濟效率也起著重要作(zuo)用(yong)(yong)(yong)(yong)(yong)。 在(zai)本文中(zhong)(zhong)，我(wo)們(men)將講述化工(gong)(gong)與制藥(yao)加(jia)工(gong)(gong)技術(shu)中(zhong)(zhong)最常用(yong)(yong)(yong)(yong)(yong)的(de)(de)(de)(de)三(san)種真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)技術(shu)。 水(shui)(shui)環(huan)(huan)(huan)(huan)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng), 干式螺(luo)桿真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng), 油潤滑旋片(pian)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)。 水(shui)(shui)環(huan)(huan)(huan)(huan)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng) 水(shui)(shui)環(huan)(huan)(huan)(huan)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)適用(yong)(yong)(yong)(yong)(yong)于(yu)多(duo)種應用(yong)(yong)(yong)(yong)(yong)。它(ta)們(men)屬于(yu)旋轉正排量泵(beng)(beng)(beng)，葉(xie)輪偏(pian)心(xin)放置在(zai)圓柱形(xing)外(wai)殼(ke)中(zhong)(zhong)(圖 2)。一(yi)般用(yong)(yong)(yong)(yong)(yong)水(shui)(shui)充當工(gong)(gong)作(zuo)液。葉(xie)輪旋轉時(shi)(shi)，會在(zai)密(mi)封各葉(xie)片(pian)空(kong)(kong)(kong)(kong)間的(de)(de)(de)(de)外(wai)殼(ke)內形(xing)成水(shui)(shui)環(huan)(huan)(huan)(huan)。氣(qi)(qi)體(ti)(ti)(ti)在(zai)中(zhong)(zhong)心(xin)、各葉(xie)片(pian)和液體(ti)(ti)(ti)環(huan)(huan)(huan)(huan)間形(xing)成的(de)(de)(de)(de)空(kong)(kong)(kong)(kong)間中(zhong)(zhong)輸送。由(you)于(yu)葉(xie)輪安裝(zhuang)于(yu)偏(pian)心(xin)位置，這部分空(kong)(kong)(kong)(kong)間的(de)(de)(de)(de)體(ti)(ti)(ti)積(ji)會增大，從(cong)而經進(jin)氣(qi)(qi)口(kou)吸入介質(zhi)。當葉(xie)輪繼續(xu)旋轉時(shi)(shi)，空(kong)(kong)(kong)(kong)間體(ti)(ti)(ti)積(ji)減少，氣(qi)(qi)體(ti)(ti)(ti)介質(zhi)被壓縮，然(ran)后(hou)通過(guo)排氣(qi)(qi)口(kou)被再次排出。水(shui)(shui)環(huan)(huan)(huan)(huan)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)既可(ke)作(zuo)為單一(yi)的(de)(de)(de)(de)連續(xu)流系(xi)統運行，也可(ke)作(zuo)為部分或(huo)全循環(huan)(huan)(huan)(huan)系(xi)統運行。 多(duo)年(nian)來，經實踐證(zheng)明，這些真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)在(zai)化學(xue)工(gong)(gong)藝中(zhong)(zhong)是堅固耐用(yong)(yong)(yong)(yong)(yong)、質(zhi)量可(ke)靠(kao)的(de)(de)(de)(de)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)發生器。壓縮室(shi)內的(de)(de)(de)(de)工(gong)(gong)作(zuo)液不斷(duan)耗散壓縮熱，因此真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)運行幾乎(hu)是等(deng)溫的(de)(de)(de)(de)。這意味著工(gong)(gong)藝氣(qi)(qi)體(ti)(ti)(ti)不會明顯升溫，真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)在(zai)相(xiang)對較低的(de)(de)(de)(de)溫度下運行。這將顯著降低不必要的(de)(de)(de)(de)反應或(huo)爆炸(zha)的(de)(de)(de)(de)風險。低工(gong)(gong)作(zuo)溫度還(huan)有利于(yu)蒸汽和氣(qi)(qi)體(ti)(ti)(ti)的(de)(de)(de)(de)冷凝，提升真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)額定(ding)(ding)泵(beng)(beng)(beng)速。 一(yi)般用(yong)(yong)(yong)(yong)(yong)水(shui)(shui)來作(zuo)為水(shui)(shui)環(huan)(huan)(huan)(huan)。在(zai)實際應用(yong)(yong)(yong)(yong)(yong)中(zhong)(zhong)，還(huan)經常使用(yong)(yong)(yong)(yong)(yong)乙(yi)二醇、礦物油或(huo)有機溶劑。真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)極...

離(li)心泵(beng)(beng)(beng)有很多不(bu)(bu)同的類(lei)(lei)型，對(dui)(dui)于不(bu)(bu)同液(ye)體(ti)需要(yao)選(xuan)(xuan)(xuan)擇(ze)不(bu)(bu)同的離(li)心泵(beng)(beng)(beng)，液(ye)體(ti)粘度不(bu)(bu)大(da)、流量(liang)(liang)較(jiao)大(da)、揚程不(bu)(bu)高時，宜選(xuan)(xuan)(xuan)用往(wang)復(fu)泵(beng)(beng)(beng)；液(ye)體(ti)粘度較(jiao)大(da)、流量(liang)(liang)較(jiao)小、揚程不(bu)(bu)高或(huo)(huo)含(han)有氣泡時，可選(xuan)(xuan)(xuan)用旋(xuan)渦泵(beng)(beng)(beng)；液(ye)體(ti)粘度較(jiao)大(da)、流量(liang)(liang)較(jiao)小、揚程較(jiao)高時，宜選(xuan)(xuan)(xuan)用轉(zhuan)子(zi)泵(beng)(beng)(beng)。 理解類(lei)(lei)型的選(xuan)(xuan)(xuan)擇(ze)是最基本的，只有正確選(xuan)(xuan)(xuan)擇(ze)才能(neng)使得正常運轉(zhuan)，但是我們(men)在使用中經常會遇到突然泄(xie)漏(lou)(lou)的問題(ti)，這又是哪些原因造成的呢(ni)？下面(mian)就來分析一(yi)下。 1、抽空、氣蝕(shi)或(huo)(huo)較(jiao)長時間憋壓，導(dao)(dao)致(zhi)密(mi)封(feng)(feng)破壞； 2、對(dui)(dui)泵(beng)(beng)(beng)實(shi)際(ji)輸出(chu)量(liang)(liang)偏(pian)小，大(da)量(liang)(liang)介(jie)質泵(beng)(beng)(beng)內循環，熱量(liang)(liang)積聚(ju)，引(yin)起(qi)介(jie)質氣化，導(dao)(dao)致(zhi)密(mi)封(feng)(feng)失效(xiao)； 3、回流量(liang)(liang)偏(pian)大(da)，導(dao)(dao)致(zhi)吸人管側容(rong)器(塔、釜、罐、池(chi))底部沉渣泛起(qi)，損(sun)壞密(mi)封(feng)(feng)； 4、對(dui)(dui)較(jiao)長時間停運，重新起(qi)動時沒(mei)有手(shou)動盤車(che)，摩擦副因粘連而(er)扯(che)壞密(mi)封(feng)(feng)面(mian)； 5、介(jie)質中腐蝕(shi)性、聚(ju)合性、結膠(jiao)性物(wu)質增多； 6、環境(jing)溫度急劇變(bian)化； 7、工況(kuang)頻繁(fan)變(bian)化或(huo)(huo)調整； 8、突然停電或(huo)(huo)故障停機等。 當遇到突然泄(xie)漏(lou)(lou)的問題(ti)，我們(men)一(yi)定要(yao)正確分析，以采取對(dui)(dui)的措施，以免造成不(bu)(bu)要(yao)的損(sun)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?
