為化工(gong)(gong)與(yu)制藥工(gong)(gong)藝應用(yong)(yong)(yong)選擇合適(shi)的(de)(de)(de)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)技術(shu)(shu)往往并非(fei)易(yi)事。首(shou)先，真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)系(xi)(xi)統必須在工(gong)(gong)作壓(ya)力下(xia)提(ti)供(gong)所(suo)需泵(beng)速，確(que)保所(suo)需抽真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)時間(jian)(jian)。其次，它(ta)不能對工(gong)(gong)藝氣(qi)體(ti)敏感(gan)，在用(yong)(yong)(yong)于 CIP(在位清洗(xi))清洗(xi)和氣(qi)體(ti)回(hui)收時必須滿足所(suo)有(you)要求。此外，在確(que)定要使用(yong)(yong)(yong)哪(na)種真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)技術(shu)(shu)時，穩(wen)定性和經(jing)濟效率(lv)也起著重要作用(yong)(yong)(yong)。 在本文中(zhong)，我(wo)們將(jiang)講述(shu)化工(gong)(gong)與(yu)制藥加工(gong)(gong)技術(shu)(shu)中(zhong)最常用(yong)(yong)(yong)的(de)(de)(de)三種真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)技術(shu)(shu)。 水(shui)(shui)環(huan)(huan)(huan)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng), 干式螺(luo)桿(gan)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng), 油潤滑(hua)旋(xuan)片(pian)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)。 水(shui)(shui)環(huan)(huan)(huan)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng) 水(shui)(shui)環(huan)(huan)(huan)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)適(shi)用(yong)(yong)(yong)于多種應用(yong)(yong)(yong)。它(ta)們屬于旋(xuan)轉正排量泵(beng)，葉(xie)輪(lun)偏(pian)心放置在圓柱形外殼中(zhong)(圖 2)。一(yi)般(ban)用(yong)(yong)(yong)水(shui)(shui)充(chong)當工(gong)(gong)作液(ye)(ye)。葉(xie)輪(lun)旋(xuan)轉時，會(hui)在密封各葉(xie)片(pian)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)間(jian)(jian)的(de)(de)(de)外殼內(nei)形成水(shui)(shui)環(huan)(huan)(huan)。氣(qi)體(ti)在中(zhong)心、各葉(xie)片(pian)和液(ye)(ye)體(ti)環(huan)(huan)(huan)間(jian)(jian)形成的(de)(de)(de)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)間(jian)(jian)中(zhong)輸送。由于葉(xie)輪(lun)安裝于偏(pian)心位置，這(zhe)部分空(kong)(kong)(kong)(kong)(kong)(kong)(kong)間(jian)(jian)的(de)(de)(de)體(ti)積會(hui)增(zeng)大(da)，從而經(jing)進氣(qi)口吸入介質。當葉(xie)輪(lun)繼續旋(xuan)轉時，空(kong)(kong)(kong)(kong)(kong)(kong)(kong)間(jian)(jian)體(ti)積減(jian)少，氣(qi)體(ti)介質被壓(ya)縮，然后通過排氣(qi)口被再次排出。水(shui)(shui)環(huan)(huan)(huan)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)既可作為單一(yi)的(de)(de)(de)連續流系(xi)(xi)統運行(xing)，也可作為部分或(huo)全循環(huan)(huan)(huan)系(xi)(xi)統運行(xing)。 多年來(lai)，經(jing)實(shi)踐證明(ming)，這(zhe)些真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)在化學工(gong)(gong)藝中(zhong)是(shi)堅固(gu)耐用(yong)(yong)(yong)、質量可靠的(de)(de)(de)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)發生器(qi)。壓(ya)縮室內(nei)的(de)(de)(de)工(gong)(gong)作液(ye)(ye)不斷耗(hao)散壓(ya)縮熱，因此真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)的(de)(de)(de)運行(xing)幾乎是(shi)等溫的(de)(de)(de)。這(zhe)意味著工(gong)(gong)藝氣(qi)體(ti)不會(hui)明(ming)顯升溫，真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)在相對較低的(de)(de)(de)溫度下(xia)運行(xing)。這(zhe)將(jiang)顯著降低不必要的(de)(de)(de)反應或(huo)爆炸的(de)(de)(de)風險。低工(gong)(gong)作溫度還(huan)有(you)利于蒸(zheng)汽(qi)和氣(qi)體(ti)的(de)(de)(de)冷(leng)凝，提(ti)升真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)的(de)(de)(de)額定泵(beng)速。 一(yi)般(ban)用(yong)(yong)(yong)水(shui)(shui)來(lai)作為水(shui)(shui)環(huan)(huan)(huan)。在實(shi)際應用(yong)(yong)(yong)中(zhong)，還(huan)經(jing)常使用(yong)(yong)(yong)乙二醇、礦(kuang)物油或(huo)有(you)機溶劑。真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)的(de)(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，?
