為(wei)化工(gong)(gong)(gong)(gong)與制藥(yao)工(gong)(gong)(gong)(gong)藝(yi)(yi)應(ying)用(yong)(yong)選擇合適(shi)的(de)(de)真(zhen)(zhen)(zhen)空技(ji)術往往并(bing)非易事。首先，真(zhen)(zhen)(zhen)空系統必須(xu)在(zai)(zai)(zai)工(gong)(gong)(gong)(gong)作(zuo)壓力下提供(gong)所需(xu)泵(beng)(beng)速(su)，確(que)保(bao)所需(xu)抽(chou)真(zhen)(zhen)(zhen)空時間(jian)(jian)。其次(ci)，它不能對工(gong)(gong)(gong)(gong)藝(yi)(yi)氣(qi)(qi)體(ti)敏感(gan)，在(zai)(zai)(zai)用(yong)(yong)于(yu) CIP(在(zai)(zai)(zai)位清洗)清洗和(he)(he)氣(qi)(qi)體(ti)回收(shou)時必須(xu)滿足所有(you)要求。此外(wai)，在(zai)(zai)(zai)確(que)定(ding)(ding)要使用(yong)(yong)哪種(zhong)真(zhen)(zhen)(zhen)空技(ji)術時，穩(wen)定(ding)(ding)性和(he)(he)經濟(ji)效率也(ye)起(qi)著重要作(zuo)用(yong)(yong)。 在(zai)(zai)(zai)本文(wen)中(zhong)(zhong)(zhong)，我們(men)將講述化工(gong)(gong)(gong)(gong)與制藥(yao)加(jia)工(gong)(gong)(gong)(gong)技(ji)術中(zhong)(zhong)(zhong)最常(chang)用(yong)(yong)的(de)(de)三種(zhong)真(zhen)(zhen)(zhen)空技(ji)術。 水(shui)(shui)環(huan)(huan)真(zhen)(zhen)(zhen)空泵(beng)(beng), 干式螺桿真(zhen)(zhen)(zhen)空泵(beng)(beng), 油潤滑旋(xuan)(xuan)片(pian)真(zhen)(zhen)(zhen)空泵(beng)(beng)。 水(shui)(shui)環(huan)(huan)真(zhen)(zhen)(zhen)空泵(beng)(beng) 水(shui)(shui)環(huan)(huan)真(zhen)(zhen)(zhen)空泵(beng)(beng)適(shi)用(yong)(yong)于(yu)多種(zhong)應(ying)用(yong)(yong)。它們(men)屬于(yu)旋(xuan)(xuan)轉正排(pai)量(liang)(liang)泵(beng)(beng)，葉(xie)(xie)輪(lun)偏(pian)心放置(zhi)(zhi)在(zai)(zai)(zai)圓柱形外(wai)殼中(zhong)(zhong)(zhong)(圖 2)。一(yi)般(ban)用(yong)(yong)水(shui)(shui)充(chong)當工(gong)(gong)(gong)(gong)作(zuo)液(ye)。葉(xie)(xie)輪(lun)旋(xuan)(xuan)轉時，會在(zai)(zai)(zai)密(mi)封各葉(xie)(xie)片(pian)空間(jian)(jian)的(de)(de)外(wai)殼內形成(cheng)(cheng)水(shui)(shui)環(huan)(huan)。氣(qi)(qi)體(ti)在(zai)(zai)(zai)中(zhong)(zhong)(zhong)心、各葉(xie)(xie)片(pian)和(he)(he)液(ye)體(ti)環(huan)(huan)間(jian)(jian)形成(cheng)(cheng)的(de)(de)空間(jian)(jian)中(zhong)(zhong)(zhong)輸送。由于(yu)葉(xie)(xie)輪(lun)安裝于(yu)偏(pian)心位置(zhi)(zhi)，這部(bu)分空間(jian)(jian)的(de)(de)體(ti)積(ji)會增(zeng)大，從而經進氣(qi)(qi)口吸(xi)入介(jie)質。當葉(xie)(xie)輪(lun)繼續(xu)旋(xuan)(xuan)轉時，空間(jian)(jian)體(ti)積(ji)減少，氣(qi)(qi)體(ti)介(jie)質被壓縮(suo)，然后通過排(pai)氣(qi)(qi)口被再次(ci)排(pai)出。水(shui)(shui)環(huan)(huan)真(zhen)(zhen)(zhen)空泵(beng)(beng)既可作(zuo)為(wei)單一(yi)的(de)(de)連(lian)續(xu)流系統運(yun)行，也(ye)可作(zuo)為(wei)部(bu)分或全循環(huan)(huan)系統運(yun)行。 多年來，經實踐證(zheng)明，這些真(zhen)(zhen)(zhen)空泵(beng)(beng)在(zai)(zai)(zai)化學工(gong)(gong)(gong)(gong)藝(yi)(yi)中(zhong)(zhong)(zhong)是堅固(gu)耐用(yong)(yong)、質量(liang)(liang)可靠的(de)(de)真(zhen)(zhen)(zhen)空發生器。壓縮(suo)室內的(de)(de)工(gong)(gong)(gong)(gong)作(zuo)液(ye)不斷耗散壓縮(suo)熱，因此真(zhen)(zhen)(zhen)空泵(beng)(beng)的(de)(de)運(yun)行幾乎是等溫(wen)的(de)(de)。這意味著工(gong)(gong)(gong)(gong)藝(yi)(yi)氣(qi)(qi)體(ti)不會明顯升溫(wen)，真(zhen)(zhen)(zhen)空泵(beng)(beng)在(zai)(zai)(zai)相對較低(di)(di)的(de)(de)溫(wen)度(du)下運(yun)行。這將顯著降低(di)(di)不必要的(de)(de)反應(ying)或爆炸的(de)(de)風險。低(di)(di)工(gong)(gong)(gong)(gong)作(zuo)溫(wen)度(du)還有(you)利(li)于(yu)蒸汽(qi)和(he)(he)氣(qi)(qi)體(ti)的(de)(de)冷凝，提升真(zhen)(zhen)(zhen)空泵(beng)(beng)的(de)(de)額(e)定(ding)(ding)泵(beng)(beng)速(su)。 一(yi)般(ban)用(yong)(yong)水(shui)(shui)來作(zuo)為(wei)水(shui)(shui)環(huan)(huan)。在(zai)(zai)(zai)實際應(ying)用(yong)(yong)中(zhong)(zhong)(zhong)，還經常(chang)使用(yong)(yong)乙二醇(chun)、礦物油或有(you)機(ji)溶劑。真(zhen)(zhen)(zhen)空泵(beng)(beng)的(de)(de)極...

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
