結構緊(jin)湊，泵(beng)(beng)的(de)(de)(de)轉數較高，一般(ban)可與電動(dong)機直聯，無須減速(su)(su)裝置(zhi)。故用(yong)小的(de)(de)(de)結構尺寸，真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)生(sheng)產廠，可以(yi)獲得大的(de)(de)(de)排(pai)氣量，占(zhan)地(di)面積也小。隨著真(zhen)(zhen)(zhen)空(kong)(kong)(kong)技術在(zai)應(ying)(ying)用(yong)壓強范圍(wei)的(de)(de)(de)要求越來越寬，大多需要由幾(ji)種真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)組(zu)成真(zhen)(zhen)(zhen)空(kong)(kong)(kong)抽氣系統共同抽氣后才能滿足生(sheng)產和科學(xue)研究過程的(de)(de)(de)要求，真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)相(xiang)關下游應(ying)(ying)用(yong)行業保持(chi)快速(su)(su)增長，同時在(zai)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)應(ying)(ying)用(yong)領域(yu)不(bu)斷拓(tuo)展(zhan)等因素的(de)(de)(de)共同拉動(dong)下，我國真(zhen)(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)行業實現了持(chi)續穩定地(di)快速(su)(su)的(de)(de)(de)發(fa)展(zhan)。

真(zhen)空(kong)(kong)泵(beng)工(gong)(gong)(gong)作(zuo)時產生的振(zhen)動(dong)(dong)(dong)對工(gong)(gong)(gong)藝過程(cheng)及環(huan)境有無(wu)影響。若工(gong)(gong)(gong)藝過程(cheng)不(bu)允許，應選擇無(wu)振(zhen)動(dong)(dong)(dong)的泵(beng)或者采取(qu)防(fang)振(zhen)動(dong)(dong)(dong)措施。水環(huan)式真(zhen)空(kong)(kong)泵(beng)初(chu)用(yong)(yong)作(zuo)自吸水泵(beng)，而后(hou)逐(zhu)漸用(yong)(yong)于石(shi)油、化工(gong)(gong)(gong)、機械、礦山、輕(qing)工(gong)(gong)(gong)、醫i藥(yao)及食品等許多工(gong)(gong)(gong)業(ye)部門(men)。真(zhen)空(kong)(kong)泵(beng)相關下游應用(yong)(yong)行業(ye)保持(chi)快(kuai)(kuai)速增長，同時在真(zhen)空(kong)(kong)泵(beng)應用(yong)(yong)領域不(bu)斷拓展等因素的共同拉動(dong)(dong)(dong)下，我國真(zhen)空(kong)(kong)泵(beng)行業(ye)實現(xian)了持(chi)續穩定地(di)快(kuai)(kuai)速的發展。

了解被(bei)(bei)抽(chou)氣體成(cheng)分，氣體中(zhong)含(han)(han)不含(han)(han)可凝(ning)蒸氣，有無顆粒灰(hui)塵，有無腐蝕(shi)性等(deng)。選擇(ze)(ze)真空泵(beng)(beng)時，需(xu)要(yao)知道氣體成(cheng)分，針(zhen)對被(bei)(bei)抽(chou)氣體選擇(ze)(ze)相(xiang)應的(de)(de)泵(beng)(beng)。檢查確定達到要(yao)求的(de)(de)真空度所(suo)需(xu)要(yao)的(de)(de)時間、真空管(guan)道的(de)(de)流(liu)阻與泄(xie)漏。考慮達到要(yao)求真空度后在(zai)一(yi)定工藝要(yao)求條(tiao)件下維持真空需(xu)要(yao)的(de)(de)抽(chou)氣速率。

真(zhen)空(kong)泵(beng)是指利用機械、物理(li)、化學或物理(li)化學的(de)方法對被抽容器進行抽氣(qi)而(er)獲(huo)得真(zhen)空(kong)的(de)器件或設備。低溫泵(beng)：利用低溫表面捕集氣(qi)體(ti)的(de)真(zhen)空(kong)泵(beng)。
