通(tong)(tong)俗(su)來講，真空泵是用各種(zhong)方法在某一封(feng)閉空間(jian)中改(gai)善、產生和維持真空的裝置。在泵腔內(nei)形(xing)成通(tong)(tong)過(guo)旋轉產生體積的變化而將(jiang)氣(qi)(qi)體排出(chu)泵外，主要是在吸(xi)(xi)氣(qi)(qi)過(guo)程(cheng)中，吸(xi)(xi)氣(qi)(qi)腔體積增(zeng)大，真空度降低，將(jiang)容器內(nei)氣(qi)(qi)體吸(xi)(xi)入泵腔，在排氣(qi)(qi)過(guo)程(cheng)中體積變小，壓(ya)強增(zeng)大，最終通(tong)(tong)過(guo)油封(feng)將(jiang)吸(xi)(xi)入的氣(qi)(qi)體排出(chu)泵外。

按真空(kong)泵(beng)(beng)的工作(zuo)原理，真空(kong)泵(beng)(beng)基本上可以分為兩種類型(xing)，即氣(qi)體捕集泵(beng)(beng)和(he)氣(qi)體傳輸泵(beng)(beng)。

特點

(1)在較(jiao)寬的壓(ya)力(li)范(fan)圍內有較(jiao)大的抽速(su)；

(2)轉(zhuan)子(zi)(zi)(zi)具有(you)良好(hao)的(de)幾何對(dui)(dui)稱(cheng)性，故振動小，運轉(zhuan)平穩(wen)。轉(zhuan)子(zi)(zi)(zi)間及轉(zhuan)子(zi)(zi)(zi)和(he)殼(ke)體(ti)間均有(you)間隙，不(bu)用潤滑(hua)(hua)，摩擦損失小，可(ke)(ke)大大降低驅(qu)動功率，從而(er)可(ke)(ke)實(shi)現(xian)較(jiao)高轉(zhuan)速；(3)泵(beng)腔內(nei)無需(xu)用油密封(feng)和(he)潤滑(hua)(hua)，可(ke)(ke)減少油蒸氣(qi)對(dui)(dui)真(zhen)空系統的(de)污染(ran)；(4)泵(beng)腔內(nei)無壓縮(suo)，無排氣(qi)閥。結構簡單(dan)、緊湊，對(dui)(dui)被抽(chou)氣(qi)體(ti)中的(de)灰塵和(he)水蒸汽不(bu)敏感(gan)；(5)壓縮(suo)比較(jiao)低，對(dui)(dui)氫氣(qi)抽(chou)氣(qi)效果差；(6)轉(zhuan)子(zi)(zi)(zi)表面為(wei)形(xing)狀(zhuang)較(jiao)為(wei)復雜(za)的(de)曲線柱面，加工(gong)和(he)檢(jian)查比較(jiao)困難(nan)。

真空泵的種類和用途

根據(ju)使用(yong)(yong)(yong)(yong)的(de)(de)范圍和(he)抽(chou)(chou)(chou)氣(qi)(qi)效能(neng)(neng)(neng)可(ke)將(jiang)真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)分為(wei)三類： 　　(1)一(yi)般水(shui)(shui)(shui)泵(beng)(beng)(beng)(beng)(beng)(beng)，壓(ya)(ya)(ya)(ya)強可(ke)達(da)(da)到(dao)1.333~100kPa(10~760mmHg)為(wei)"粗"真(zhen)(zhen)(zhen)空(kong)。 　　(2)油(you)(you)(you)泵(beng)(beng)(beng)(beng)(beng)(beng)，壓(ya)(ya)(ya)(ya)強可(ke)達(da)(da)0.133~133.3Pa(0.001~1mmHg)為(wei)"次高(gao)"真(zhen)(zhen)(zhen)空(kong)。 　　(3)擴散泵(beng)(beng)(beng)(beng)(beng)(beng)，壓(ya)(ya)(ya)(ya)強可(ke)達(da)(da)0.133Pa以下，(10-3mmHg)為(wei)"高(gao)"真(zhen)(zhen)(zhen)空(kong)。 　　在(zai)有(you)(you)(you)機(ji)化學實驗(yan)室里常用(yong)(yong)(yong)(yong)的(de)(de)減(jian)壓(ya)(ya)(ya)(ya)泵(beng)(beng)(beng)(beng)(beng)(beng)有(you)(you)(you)水(shui)(shui)(shui)泵(beng)(beng)(beng)(beng)(beng)(beng)和(he)油(you)(you)(you)泵(beng)(beng)(beng)(beng)(beng)(beng)兩種，若(ruo)不要(yao)(yao)求(qiu)很低(di)的(de)(de)壓(ya)(ya)(ya)(ya)力(li)時(shi)(shi)，可(ke)用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)泵(beng)(beng)(beng)(beng)(beng)(beng)，如(ru)果水(shui)(shui)(shui)泵(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)構造好且水(shui)(shui)(shui)壓(ya)(ya)(ya)(ya)又高(gao)，抽(chou)(chou)(chou)空(kong)效率可(ke)達(da)(da)1067~3333Pa(8~25mmHg)。水(shui)(shui)(shui)泵(beng)(beng)(beng)(beng)(beng)(beng)所(suo)能(neng)(neng)(neng)抽(chou)(chou)(chou)到(dao)的(de)(de)低(di)壓(ya)(ya)(ya)(ya)力(li)理論(lun)上(shang)(shang)相當(dang)于(yu)當(dang)時(shi)(shi)水(shui)(shui)(shui)溫下的(de)(de)水(shui)(shui)(shui)蒸(zheng)氣(qi)(qi)壓(ya)(ya)(ya)(ya)力(li)。例如(ru)，水(shui)(shui)(shui)溫25℃、20℃、10℃時(shi)(shi)，水(shui)(shui)(shui)蒸(zheng)氣(qi)(qi)的(de)(de)壓(ya)(ya)(ya)(ya)力(li)分別(bie)為(wei)3192、2394、1197Pa(8-25mmHg)。用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)泵(beng)(beng)(beng)(beng)(beng)(beng)抽(chou)(chou)(chou)氣(qi)(qi)時(shi)(shi)，應在(zai)水(shui)(shui)(shui)泵(beng)(beng)(beng)(beng)(beng)(beng)前(qian)裝上(shang)(shang)安(an)全瓶，以防水(shui)(shui)(shui)壓(ya)(ya)(ya)(ya)下降(jiang)，水(shui)(shui)(shui)流倒吸(xi)(xi)(xi);停(ting)止抽(chou)(chou)(chou)氣(qi)(qi)前(qian)，應先放氣(qi)(qi)，然后關水(shui)(shui)(shui)泵(beng)(beng)(beng)(beng)(beng)(beng)。 　　若(ruo)要(yao)(yao)較低(di)的(de)(de)壓(ya)(ya)(ya)(ya)力(li)，那(nei)就(jiu)要(yao)(yao)用(yong)(yong)(yong)(yong)到(dao)油(you)(you)(you)泵(beng)(beng)(beng)(beng)(beng)(beng)了，好的(de)(de)油(you)(you)(you)泵(beng)(beng)(beng)(beng)(beng)(beng)能(neng)(neng)(neng)抽(chou)(chou)(chou)到(dao)133.3Pa(1mmHg)以下。油(you)(you)(you)泵(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)好壞決(jue)定(ding)于(yu)其機(ji)械結構和(he)油(you)(you)(you)的(de)(de)質(zhi)量，使用(yong)(yong)(yong)(yong)油(you)(you)(you)泵(beng)(beng)(beng)(beng)(beng)(beng)時(shi)(shi)必須把它保(bao)護好。如(ru)果蒸(zheng)餾(liu)(liu)揮發(fa)性較大(da)的(de)(de)有(you)(you)(you)機(ji)溶劑(ji)時(shi)(shi)，有(you)(you)(you)機(ji)溶劑(ji)會被油(you)(you)(you)吸(xi)(xi)(xi)收結果增加(jia)了蒸(zheng)氣(qi)(qi)壓(ya)(ya)(ya)(ya)，從而(er)(er)降(jiang)低(di)了抽(chou)(chou)(chou)空(kong)效能(neng)(neng)(neng)，如(ru)果是(shi)酸性氣(qi)(qi)體，那(nei)就(jiu)會腐蝕油(you)(you)(you)泵(beng)(beng)(beng)(beng)(beng)(beng)，如(ru)果是(shi)水(shui)(shui)(shui)蒸(zheng)氣(qi)(qi)就(jiu)會使油(you)(you)(you)成乳濁液而(er)(er)抽(chou)(chou)(chou)壞真(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)。因此使用(yong)(yong)(yong)(yong)油(you)(you)(you)泵(beng)(beng)(beng)(beng)(beng)(beng)時(shi)(shi)必須注意下列幾點： 　　在(zai)蒸(zheng)餾(liu)(liu)系統和(he)油(you)(you)(you)泵(beng)(beng)(beng)(beng)(beng)(beng)之(zhi)間，必須裝有(you)(you)(you)吸(xi)(xi)(xi)收裝置。 　　蒸(zheng)餾(liu)(liu)前(qian)必須用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)泵(beng)(beng)(beng)(beng)(beng)(beng)*抽(chou)(chou)(chou)去(qu)系統中有(you)(you)(you)機(ji)溶劑(ji)的(de)(de)蒸(zheng)氣(qi)(qi)。 　　如(ru)能(neng)(neng)(neng)用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)泵(beng)(beng)(beng)(beng)(beng)(beng)抽(chou)(chou)(chou)氣(qi)(qi)的(de)(de)，則盡量用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)泵(beng)(beng)(beng)(beng)(beng)(beng)，如(ru)蒸(zheng)餾(liu)(liu)物質(zhi)中含有(you)(you)(you)揮發(fa)性物質(zhi)，可(ke)先用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)泵(beng)(beng)(beng)(beng)(beng)(beng)減(jian)壓(ya)(ya)(ya)(ya)抽(chou)(chou)(chou)降(jiang)，然后改用(yong)(yong)(yong)(yong)油(you)(you)(you)泵(beng)(beng)(beng)(beng)(beng)(beng)。 　　減(jian)壓(ya)(ya)(ya)(ya)系統必須保(bao)持密不漏氣(qi)(qi)，所(suo)有(you)(you)(you)的(de)(de)橡(xiang)皮(pi)塞(sai)的(de)(de)大(da)小(xiao)和(he)孔道要(yao)(yao)合適，橡(xiang)皮(pi)管(guan)要(yao)(yao)用(yong)(yong)(yong)(yong)真(zhen)(zhen)(zhen)空(kong)用(yong)(yong)(yong)(yong)的(de)(de)橡(xiang)皮(pi)管(guan)。磨(mo)口玻璃涂上(shang)(shang)真(zhen)(zhen)(zhen)空(kong)油(you)(you)(you)脂。

原理是利用(yong)偏心轉子在(zai)泵(beng)腔內(nei)形成通(tong)過(guo)(guo)旋(xuan)轉產生體(ti)(ti)(ti)(ti)積的變(bian)化而將氣(qi)體(ti)(ti)(ti)(ti)排出泵(beng)外(wai)，主要是在(zai)吸氣(qi)過(guo)(guo)程(cheng)中(zhong)(zhong)，吸氣(qi)腔體(ti)(ti)(ti)(ti)積增大(da)，真空(kong)度降低(di)，將容器(qi)內(nei)氣(qi)體(ti)(ti)(ti)(ti)吸入泵(beng)腔，在(zai)排氣(qi)過(guo)(guo)程(cheng)中(zhong)(zhong)體(ti)(ti)(ti)(ti)積變(bian)小，壓強增大(da)，最終通(tong)過(guo)(guo)油封將吸入的氣(qi)體(ti)(ti)(ti)(ti)排出泵(beng)外(wai)。

使用真(zhen)空(kong)泵的注(zhu)意事項：

正常(chang)運傳前，真(zhen)(zhen)(zhen)空泵(beng)應(ying)先(xian)做一(yi)次(ci)試運轉，檢查(cha)真(zhen)(zhen)(zhen)空泵(beng)有(you)無(wu)異常(chang)振動及沖(chong)擊(ji)聲響。初次(ci)使用(yong)的(de)(de)(de)真(zhen)(zhen)(zhen)空泵(beng)還(huan)要測(ce)定(ding)真(zhen)(zhen)(zhen)空泵(beng)的(de)(de)(de)極(ji)限壓強，應(ying)符合技術(shu)規范。真(zhen)(zhen)(zhen)空泵(beng)在長期工作的(de)(de)(de)條件(jian)下(xia)，真(zhen)(zhen)(zhen)空泵(beng)溫不(bu)應(ying)超過70度。至于抽速的(de)(de)(de)測(ce)定(ding).由于比較復雜，一(yi)般不(bu)作檢查(cha)。

需要通冷卻(que)水的機(ji)械真空泵(beng).在開(kai)機(ji)前(qian)應先通冷卻(que)水，然后再啟動(dong)。冷卻(que)水的出口水溫不宜超過30度(du)。

次安裝真空泵(beng)時，應檢(jian)查(cha)電(dian)機(ji)是否(fou)正轉(zhuan)，也就是電(dian)機(ji)與真空泵(beng)內(nei)轉(zhuan)子轉(zhuan)向一致，一般電(dian)機(ji)上方(fang)(fang)標有(you)電(dian)機(ji)正常運轉(zhuan)方(fang)(fang)向。真空設備應安裝在清潔、干(gan)凈的環境里，不宜有(you)雜物、粉(fen)塵(chen)、水(shui)源，溫度過(guo)高的地方(fang)(fang)也不適(shi)合。
