為(wei)化(hua)(hua)工(gong)與(yu)制(zhi)藥工(gong)藝應(ying)用選擇合適的(de)(de)真(zhen)(zhen)空(kong)(kong)(kong)(kong)技術(shu)(shu)往往并非易事。首先,真(zhen)(zhen)空(kong)(kong)(kong)(kong)系(xi)統必須在(zai)工(gong)作(zuo)(zuo)壓(ya)力下(xia)提(ti)(ti)供(gong)所需泵(beng)(beng)速,確保所需抽真(zhen)(zhen)空(kong)(kong)(kong)(kong)時間(jian)。其次(ci),它(ta)不能對(dui)工(gong)藝氣(qi)體敏感,在(zai)用于(yu) CIP(在(zai)位清洗)清洗和氣(qi)體回(hui)收(shou)時必須滿足所有(you)要(yao)求。此外,在(zai)確定要(yao)使(shi)用哪(na)種真(zhen)(zhen)空(kong)(kong)(kong)(kong)技術(shu)(shu)時,穩定性和經(jing)(jing)濟效率也起著(zhu)重要(yao)作(zuo)(zuo)用。 在(zai)本(ben)文中,我們(men)將講述化(hua)(hua)工(gong)與(yu)制(zhi)藥加工(gong)技術(shu)(shu)中最(zui)常用的(de)(de)三種真(zhen)(zhen)空(kong)(kong)(kong)(kong)技術(shu)(shu)。 水(shui)(shui)環(huan)真(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng), 干式螺桿真(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng), 油潤滑旋片真(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)。 水(shui)(shui)環(huan)真(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng) 水(shui)(shui)環(huan)真(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)適用于(yu)多種應(ying)用。它(ta)們(men)屬于(yu)旋轉(zhuan)正(zheng)排(pai)量泵(beng)(beng),葉輪偏(pian)心(xin)放置在(zai)圓柱形(xing)外殼中(圖(tu) 2)。一般(ban)用水(shui)(shui)充當工(gong)作(zuo)(zuo)液(ye)。葉輪旋轉(zhuan)時,會(hui)在(zai)密封各葉片空(kong)(kong)(kong)(kong)間(jian)的(de)(de)外殼內形(xing)成(cheng)水(shui)(shui)環(huan)。氣(qi)體在(zai)中心(xin)、各葉片和液(ye)體環(huan)間(jian)形(xing)成(cheng)的(de)(de)空(kong)(kong)(kong)(kong)間(jian)中輸送(song)。由于(yu)葉輪安裝(zhuang)于(yu)偏(pian)心(xin)位置,這(zhe)部(bu)分空(kong)(kong)(kong)(kong)間(jian)的(de)(de)體積會(hui)增大(da),從而經(jing)(jing)進氣(qi)口吸入(ru)介質(zhi)。當葉輪繼續(xu)旋轉(zhuan)時,空(kong)(kong)(kong)(kong)間(jian)體積減(jian)少,氣(qi)體介質(zhi)被(bei)壓(ya)縮(suo),然后通過排(pai)氣(qi)口被(bei)再次(ci)排(pai)出。水(shui)(shui)環(huan)真(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)既可作(zuo)(zuo)為(wei)單一的(de)(de)連續(xu)流系(xi)統運(yun)行(xing),也可作(zuo)(zuo)為(wei)部(bu)分或(huo)全循(xun)環(huan)系(xi)統運(yun)行(xing)。 多年來,經(jing)(jing)實踐證明,這(zhe)些真(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)在(zai)化(hua)(hua)學工(gong)藝中是堅固(gu)耐用、質(zhi)量可靠的(de)(de)真(zhen)(zhen)空(kong)(kong)(kong)(kong)發生(sheng)器。壓(ya)縮(suo)室(shi)內的(de)(de)工(gong)作(zuo)(zuo)液(ye)不斷耗散壓(ya)縮(suo)熱,因此真(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)的(de)(de)運(yun)行(xing)幾乎是等溫的(de)(de)。這(zhe)意味(wei)著(zhu)工(gong)藝氣(qi)體不會(hui)明顯升溫,真(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)在(zai)相對(dui)較低的(de)(de)溫度(du)下(xia)運(yun)行(xing)。這(zhe)將顯著(zhu)降(jiang)低不必要(yao)的(de)(de)反(fan)應(ying)或(huo)爆炸的(de)(de)風險。低工(gong)作(zuo)(zuo)溫度(du)還有(you)利于(yu)蒸(zheng)汽和氣(qi)體的(de)(de)冷凝(ning),提(ti)(ti)升真(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)的(de)(de)額定泵(beng)(beng)速。 一般(ban)用水(shui)(shui)來作(zuo)(zuo)為(wei)水(shui)(shui)環(huan)。在(zai)實際應(ying)用中,還經(jing)(jing)常使(shi)用乙二醇、礦物油或(huo)有(you)機溶劑。真(zhen)(zhen)空(kong)(kong)(kong)(kong)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?
