眾所周知，對(dui)于(yu)各種真空泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)性(xing)(xing)能，都有規定的(de)(de)(de)(de)(de)(de)測試方法(fa)來測試該性(xing)(xing)能的(de)(de)(de)(de)(de)(de)性(xing)(xing)能，主要(yao)性(xing)(xing)能是極限(xian)壓(ya)(ya)(ya)(ya)力(li)，流(liu)量(liang)(liang)(liang)和抽速。這(zhe)次，小(xiao)編打(da)算(suan)討論螺(luo)(luo)桿真空泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)流(liu)量(liang)(liang)(liang)，例如如何(he)控制(zhi)(zhi)其流(liu)量(liang)(liang)(liang)，流(liu)量(liang)(liang)(liang)不足的(de)(de)(de)(de)(de)(de)原(yuan)因以(yi)及如何(he)消除此問題。相(xiang)信許(xu)多用戶對(dui)這(zhe)些問題感到困惑，不用擔(dan)心，請跟隨螺(luo)(luo)桿真空泵(beng)(beng)(beng)廠家進(jin)行了(le)解。 首(shou)先，讓我們簡單介紹一下(xia)真空泵(beng)(beng)(beng)主要(yao)性(xing)(xing)能的(de)(de)(de)(de)(de)(de)概(gai)念。 1.極限(xian)壓(ya)(ya)(ya)(ya)力(li)。真空泵(beng)(beng)(beng)與(yu)檢測容(rong)器相(xiang)連，放置待測氣(qi)(qi)(qi)(qi)體(ti)后，連續長時間(jian)(jian)抽氣(qi)(qi)(qi)(qi)。當(dang)容(rong)器的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)壓(ya)(ya)(ya)(ya)不再降(jiang)低(di)并(bing)(bing)且(qie)壓(ya)(ya)(ya)(ya)力(li)保持在(zai)一定值時，次級壓(ya)(ya)(ya)(ya)力(li)就(jiu)是泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)極限(xian)壓(ya)(ya)(ya)(ya)力(li)。 2.流(liu)量(liang)(liang)(liang)。在(zai)真空泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)吸入(ru)口，每單位時間(jian)(jian)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)流(liu)量(liang)(liang)(liang)稱為(wei)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)流(liu)量(liang)(liang)(liang)。在(zai)真空技術中，流(liu)量(liang)(liang)(liang)單位以(yi)壓(ya)(ya)(ya)(ya)力(li)*體(ti)積/時間(jian)(jian)表示，即Pa.m3/s或Pa.m3/h。通(tong)常，泵(beng)(beng)(beng)會(hui)給出(chu)流(liu)量(liang)(liang)(liang)與(yu)入(ru)口壓(ya)(ya)(ya)(ya)力(li)的(de)(de)(de)(de)(de)(de)關系(xi)圖。 3.抽速。在(zai)真空泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)吸入(ru)口，每單位時間(jian)(jian)流(liu)動(dong)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)量(liang)(liang)(liang)稱為(wei)泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)抽氣(qi)(qi)(qi)(qi)速率(lv)。即，通(tong)過將流(liu)量(liang)(liang)(liang)QA(Pa.m3/s)除以(yi)測試罩中的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)A的(de)(de)(de)(de)(de)(de)分壓(ya)(ya)(ya)(ya)pA而獲(huo)得氣(qi)(qi)(qi)(qi)體(ti)A的(de)(de)(de)(de)(de)(de)泵(beng)(beng)(beng)送速度sA(m3/s)。典型(xing)的(de)(de)(de)(de)(de)(de)真空泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)抽氣(qi)(qi)(qi)(qi)速率(lv)與(yu)氣(qi)(qi)(qi)(qi)體(ti)類型(xing)有關。給定的(de)(de)(de)(de)(de)(de)抽氣(qi)(qi)(qi)(qi)速率(lv)表示某種氣(qi)(qi)(qi)(qi)體(ti)的(de)(de)(de)(de)(de)(de)抽氣(qi)(qi)(qi)(qi)速率(lv)。如果(guo)沒(mei)有特殊指示，則使用多指抽吸。 正確控制(zhi)(zhi)螺(luo)(luo)桿真空泵(beng)(beng)(beng)流(liu)量(liang)(liang)(liang)不僅可以(yi)為(wei)設備提供(gong)良好(hao)的(de)(de)(de)(de)(de)(de)保護，還可以(yi)提高使用率(lv)。那(nei)么(me)，該怎么(me)做呢? 1，速度控制(zhi)(zhi) 葉(xie)輪速度的(de)(de)(de)(de)(de)(de)變(bian)(bian)化(hua)會(hui)改變(bian)(bian)螺(luo)(luo)桿真空泵(beng)(beng)(beng)的(de)(de)(de)(de)(de)(de)流(liu)量(liang)(liang)(liang)曲線，并(bing)(bing)且(qie)曲線的(de)(de)(de)(de)(de)(de)特性(xing)(xing)不會(hui)改變(bian)(bian)。隨著速度降(jiang)低(di)，曲線變(bian)(bian)平(ping)，揚程和流(liu)速降(jiang)低(di)。 2，旁通(tong)閥(fa)調(diao)整 使用與(yu)泵(beng)(beng)(beng)并(bing)(bing)聯的(de)(de)(de)(de)(de)(de)中間(jian)(jian)閥(fa)。實(shi)際效果(guo)就(jiu)...

為(wei)化(hua)工(gong)(gong)(gong)(gong)與(yu)制藥工(gong)(gong)(gong)(gong)藝應用(yong)(yong)選(xuan)擇合適的(de)(de)真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)技術往往并非易(yi)事。首先(xian)，真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)系統(tong)必(bi)須(xu)在(zai)工(gong)(gong)(gong)(gong)作(zuo)(zuo)壓(ya)(ya)力下提供所(suo)需(xu)泵(beng)(beng)(beng)速，確保所(suo)需(xu)抽真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)時間(jian)。其次(ci)，它不(bu)能對工(gong)(gong)(gong)(gong)藝氣體(ti)敏感，在(zai)用(yong)(yong)于(yu) CIP(在(zai)位清(qing)洗)清(qing)洗和(he)氣體(ti)回(hui)收時必(bi)須(xu)滿(man)足所(suo)有要求(qiu)。此外(wai)，在(zai)確定要使用(yong)(yong)哪種(zhong)(zhong)真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)技術時，穩定性(xing)和(he)經濟效率也(ye)(ye)起著(zhu)重要作(zuo)(zuo)用(yong)(yong)。 在(zai)本文中，我們(men)將(jiang)講述化(hua)工(gong)(gong)(gong)(gong)與(yu)制藥加工(gong)(gong)(gong)(gong)技術中最常用(yong)(yong)的(de)(de)三種(zhong)(zhong)真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)技術。 水(shui)(shui)環(huan)(huan)(huan)真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng), 干式螺(luo)桿(gan)真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng), 油潤滑(hua)旋片(pian)真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)。 水(shui)(shui)環(huan)(huan)(huan)真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng) 水(shui)(shui)環(huan)(huan)(huan)真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)適用(yong)(yong)于(yu)多種(zhong)(zhong)應用(yong)(yong)。它們(men)屬于(yu)旋轉(zhuan)(zhuan)正排(pai)(pai)(pai)量(liang)泵(beng)(beng)(beng)，葉輪偏心放置在(zai)圓(yuan)柱形外(wai)殼中(圖 2)。一(yi)(yi)般(ban)用(yong)(yong)水(shui)(shui)充當工(gong)(gong)(gong)(gong)作(zuo)(zuo)液(ye)。葉輪旋轉(zhuan)(zhuan)時，會在(zai)密封各葉片(pian)空(kong)(kong)(kong)(kong)(kong)(kong)間(jian)的(de)(de)外(wai)殼內(nei)形成水(shui)(shui)環(huan)(huan)(huan)。氣體(ti)在(zai)中心、各葉片(pian)和(he)液(ye)體(ti)環(huan)(huan)(huan)間(jian)形成的(de)(de)空(kong)(kong)(kong)(kong)(kong)(kong)間(jian)中輸送。由于(yu)葉輪安裝于(yu)偏心位置，這(zhe)部分(fen)空(kong)(kong)(kong)(kong)(kong)(kong)間(jian)的(de)(de)體(ti)積會增大，從而經進氣口(kou)吸入介質。當葉輪繼續旋轉(zhuan)(zhuan)時，空(kong)(kong)(kong)(kong)(kong)(kong)間(jian)體(ti)積減少，氣體(ti)介質被(bei)(bei)壓(ya)(ya)縮(suo)，然后通過排(pai)(pai)(pai)氣口(kou)被(bei)(bei)再次(ci)排(pai)(pai)(pai)出。水(shui)(shui)環(huan)(huan)(huan)真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)既可(ke)(ke)作(zuo)(zuo)為(wei)單一(yi)(yi)的(de)(de)連續流系統(tong)運(yun)行(xing)，也(ye)(ye)可(ke)(ke)作(zuo)(zuo)為(wei)部分(fen)或(huo)(huo)全循環(huan)(huan)(huan)系統(tong)運(yun)行(xing)。 多年來(lai)，經實踐(jian)證明，這(zhe)些真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)在(zai)化(hua)學工(gong)(gong)(gong)(gong)藝中是堅固(gu)耐用(yong)(yong)、質量(liang)可(ke)(ke)靠(kao)的(de)(de)真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)發生(sheng)器。壓(ya)(ya)縮(suo)室內(nei)的(de)(de)工(gong)(gong)(gong)(gong)作(zuo)(zuo)液(ye)不(bu)斷耗散(san)壓(ya)(ya)縮(suo)熱，因此真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)運(yun)行(xing)幾(ji)乎(hu)是等溫(wen)的(de)(de)。這(zhe)意味著(zhu)工(gong)(gong)(gong)(gong)藝氣體(ti)不(bu)會明顯(xian)升(sheng)溫(wen)，真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)在(zai)相(xiang)對較(jiao)低(di)的(de)(de)溫(wen)度(du)下運(yun)行(xing)。這(zhe)將(jiang)顯(xian)著(zhu)降低(di)不(bu)必(bi)要的(de)(de)反應或(huo)(huo)爆炸的(de)(de)風險。低(di)工(gong)(gong)(gong)(gong)作(zuo)(zuo)溫(wen)度(du)還(huan)有利于(yu)蒸汽(qi)和(he)氣體(ti)的(de)(de)冷凝，提升(sheng)真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)額(e)定泵(beng)(beng)(beng)速。 一(yi)(yi)般(ban)用(yong)(yong)水(shui)(shui)來(lai)作(zuo)(zuo)為(wei)水(shui)(shui)環(huan)(huan)(huan)。在(zai)實際(ji)應用(yong)(yong)中，還(huan)經常使用(yong)(yong)乙二醇(chun)、礦物油或(huo)(huo)有機溶劑(ji)。真(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)極(ji)...

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，請根據水環真空泵的出廠說明進行調整。注意要求，避免不當操作損壞設備 6.應及時清洗水環真空泵設備管路堵塞：異物殘留在進水管，葉輪或導流殼的流路中，會降低水環真空泵的出水量 7.防止吸入水環真空泵。當進入空氣中時
