為化工(gong)(gong)(gong)(gong)與制藥工(gong)(gong)(gong)(gong)藝(yi)應(ying)(ying)用(yong)(yong)選擇合適的(de)(de)(de)(de)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)技(ji)術(shu)(shu)往(wang)往(wang)并非易(yi)事。首(shou)先，真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)系統(tong)必須(xu)在(zai)工(gong)(gong)(gong)(gong)作(zuo)(zuo)壓(ya)力(li)下提供所需(xu)泵(beng)(beng)(beng)速，確保所需(xu)抽真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)時間。其次(ci)，它不能對工(gong)(gong)(gong)(gong)藝(yi)氣(qi)體(ti)敏感，在(zai)用(yong)(yong)于(yu)(yu) CIP(在(zai)位清(qing)洗(xi))清(qing)洗(xi)和(he)(he)氣(qi)體(ti)回收時必須(xu)滿足(zu)所有(you)要(yao)求。此外，在(zai)確定要(yao)使用(yong)(yong)哪種真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)技(ji)術(shu)(shu)時，穩定性和(he)(he)經濟(ji)效率也起(qi)著重要(yao)作(zuo)(zuo)用(yong)(yong)。 在(zai)本文中，我們(men)將講述化工(gong)(gong)(gong)(gong)與制藥加工(gong)(gong)(gong)(gong)技(ji)術(shu)(shu)中最(zui)常(chang)(chang)用(yong)(yong)的(de)(de)(de)(de)三種真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)技(ji)術(shu)(shu)。 水環(huan)(huan)(huan)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng), 干式螺桿真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng), 油潤滑(hua)旋(xuan)(xuan)片(pian)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)。 水環(huan)(huan)(huan)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng) 水環(huan)(huan)(huan)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)適用(yong)(yong)于(yu)(yu)多種應(ying)(ying)用(yong)(yong)。它們(men)屬于(yu)(yu)旋(xuan)(xuan)轉正(zheng)排量(liang)泵(beng)(beng)(beng)，葉輪(lun)偏心放(fang)置在(zai)圓柱形(xing)(xing)外殼中(圖 2)。一(yi)般(ban)用(yong)(yong)水充(chong)當工(gong)(gong)(gong)(gong)作(zuo)(zuo)液(ye)(ye)。葉輪(lun)旋(xuan)(xuan)轉時，會在(zai)密封(feng)各葉片(pian)空(kong)(kong)(kong)(kong)間的(de)(de)(de)(de)外殼內形(xing)(xing)成(cheng)水環(huan)(huan)(huan)。氣(qi)體(ti)在(zai)中心、各葉片(pian)和(he)(he)液(ye)(ye)體(ti)環(huan)(huan)(huan)間形(xing)(xing)成(cheng)的(de)(de)(de)(de)空(kong)(kong)(kong)(kong)間中輸送。由于(yu)(yu)葉輪(lun)安裝于(yu)(yu)偏心位置，這部分空(kong)(kong)(kong)(kong)間的(de)(de)(de)(de)體(ti)積(ji)會增大，從而經進氣(qi)口吸入介質(zhi)。當葉輪(lun)繼續旋(xuan)(xuan)轉時，空(kong)(kong)(kong)(kong)間體(ti)積(ji)減少，氣(qi)體(ti)介質(zhi)被壓(ya)縮(suo)(suo)，然后通過排氣(qi)口被再次(ci)排出。水環(huan)(huan)(huan)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)既可作(zuo)(zuo)為單一(yi)的(de)(de)(de)(de)連續流系統(tong)運行，也可作(zuo)(zuo)為部分或全循環(huan)(huan)(huan)系統(tong)運行。 多年來，經實(shi)踐證(zheng)明，這些真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)在(zai)化學工(gong)(gong)(gong)(gong)藝(yi)中是堅(jian)固耐用(yong)(yong)、質(zhi)量(liang)可靠的(de)(de)(de)(de)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)發(fa)生器。壓(ya)縮(suo)(suo)室內的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)作(zuo)(zuo)液(ye)(ye)不斷耗(hao)散壓(ya)縮(suo)(suo)熱，因此真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)運行幾乎是等溫的(de)(de)(de)(de)。這意味著工(gong)(gong)(gong)(gong)藝(yi)氣(qi)體(ti)不會明顯升(sheng)溫，真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)在(zai)相(xiang)對較低(di)(di)的(de)(de)(de)(de)溫度下運行。這將顯著降低(di)(di)不必要(yao)的(de)(de)(de)(de)反應(ying)(ying)或爆炸的(de)(de)(de)(de)風險。低(di)(di)工(gong)(gong)(gong)(gong)作(zuo)(zuo)溫度還(huan)有(you)利于(yu)(yu)蒸汽和(he)(he)氣(qi)體(ti)的(de)(de)(de)(de)冷凝，提升(sheng)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)額定泵(beng)(beng)(beng)速。 一(yi)般(ban)用(yong)(yong)水來作(zuo)(zuo)為水環(huan)(huan)(huan)。在(zai)實(shi)際(ji)應(ying)(ying)用(yong)(yong)中，還(huan)經常(chang)(chang)使用(yong)(yong)乙(yi)二醇、礦物油或有(you)機(ji)溶劑。真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)極...

離心(xin)(xin)泵(beng)(beng)有很(hen)多不(bu)同的類型，對(dui)于不(bu)同液(ye)(ye)體(ti)(ti)(ti)(ti)需要選(xuan)(xuan)(xuan)擇(ze)不(bu)同的離心(xin)(xin)泵(beng)(beng)，液(ye)(ye)體(ti)(ti)(ti)(ti)粘(zhan)(zhan)度(du)不(bu)大(da)(da)、流(liu)(liu)量較(jiao)(jiao)大(da)(da)、揚(yang)程不(bu)高時(shi)，宜選(xuan)(xuan)(xuan)用(yong)(yong)往(wang)復泵(beng)(beng)；液(ye)(ye)體(ti)(ti)(ti)(ti)粘(zhan)(zhan)度(du)較(jiao)(jiao)大(da)(da)、流(liu)(liu)量較(jiao)(jiao)小、揚(yang)程不(bu)高或含(han)有氣(qi)泡時(shi)，可選(xuan)(xuan)(xuan)用(yong)(yong)旋渦泵(beng)(beng)；液(ye)(ye)體(ti)(ti)(ti)(ti)粘(zhan)(zhan)度(du)較(jiao)(jiao)大(da)(da)、流(liu)(liu)量較(jiao)(jiao)小、揚(yang)程較(jiao)(jiao)高時(shi)，宜選(xuan)(xuan)(xuan)用(yong)(yong)轉子泵(beng)(beng)。 理解類型的選(xuan)(xuan)(xuan)擇(ze)是(shi)最(zui)基(ji)本(ben)的，只有正(zheng)確選(xuan)(xuan)(xuan)擇(ze)才能使得正(zheng)常(chang)運(yun)轉，但是(shi)我們在使用(yong)(yong)中經常(chang)會遇到突(tu)然泄漏的問題，這又(you)是(shi)哪些原因(yin)造成(cheng)的呢？下面(mian)就來分析一下。 1、抽空、氣(qi)蝕(shi)或較(jiao)(jiao)長時(shi)間憋(bie)壓，導致密(mi)封破壞(huai)(huai)； 2、對(dui)泵(beng)(beng)實(shi)際輸出量偏小，大(da)(da)量介質(zhi)泵(beng)(beng)內循環，熱量積聚，引起介質(zhi)氣(qi)化，導致密(mi)封失(shi)效； 3、回流(liu)(liu)量偏大(da)(da)，導致吸人(ren)管側(ce)容(rong)器(塔、釜、罐、池)底(di)部沉(chen)渣(zha)泛起，損壞(huai)(huai)密(mi)封； 4、對(dui)較(jiao)(jiao)長時(shi)間停運(yun)，重(zhong)新起動時(shi)沒(mei)有手動盤車，摩擦副(fu)因(yin)粘(zhan)(zhan)連而扯壞(huai)(huai)密(mi)封面(mian)； 5、介質(zhi)中腐蝕(shi)性、聚合性、結(jie)膠(jiao)性物(wu)質(zhi)增多； 6、環境溫度(du)急劇變化； 7、工況(kuang)頻繁(fan)變化或調整； 8、突(tu)然停電或故障(zhang)停機等。 當遇到突(tu)然泄漏的問題，我們一定要正(zheng)確分析，以采(cai)取對(dui)的措施，以免造成(cheng)不(bu)要的損失(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.如果可以保持進水清潔，則可以卸下?
