工作原理及結構特點
JZJS型機組主(zhu)要是(shi)由(you)(you)兩大(da)部分(fen)組成。即泵(beng)(beng)部分(fen)(抽氣部分(fen))和(he)(he)電源控制部分(fen)。J乙JS三級(ji)(ji)機組的(de)泵(beng)(beng)部分(fen)是(shi)由(you)(you)兩臺(tai)羅茨(ci)(ci)真空(kong)泵(beng)(beng)和(he)(he)一臺(tai)雙(shuang)級(ji)(ji)水環式真空(kong)泵(beng)(beng)三級(ji)(ji)串聯而(er)成,其中(zhong)(zhong)雙(shuang)級(ji)(ji)水環泵(beng)(beng)叫做前級(ji)(ji)泵(beng)(beng),與(yu)被(bei)抽容器(qi)相聯的(de)羅茨(ci)(ci)真空(kong)泵(beng)(beng)叫做主(zhu)泵(beng)(beng)級(ji)(ji),與(yu)前級(ji)(ji)和(he)(he)主(zhu)泵(beng)(beng)級(ji)(ji)相聯的(de)一級(ji)(ji)羅茨(ci)(ci)真空(kong)泵(beng)(beng)叫做中(zhong)(zhong)間級(ji)(ji),如果去掉中(zhong)(zhong)間級(ji)(ji)羅茨(ci)(ci)真空(kong)泵(beng)(beng),就(jiu)構成JZJS二(er)級(ji)(ji)機組。三級(ji)(ji)機組的(de)極限真空(kong)可比二(er)級(ji)(ji)機組的(de)極限真空(kong)提(ti)高(gao)一個(ge)數量級(ji)(ji)而(er)進入25Pa或更(geng)高(gao)。
由(you)于普通型羅茨(ci)真空(kong)泵(beng)(beng)不(bu)能在大(da)氣下起(qi)動,故須在其排氣端預(yu)先抽(chou)成真空(kong),然后再起(qi)動,所以在羅茨(ci)真空(kong)泵(beng)(beng)出口須配備前(qian)級(ji)(ji)真空(kong)泵(beng)(beng)(簡稱前(qian)級(ji)(ji)泵(beng)(beng))作為(wei)預(yu)抽(chou)泵(beng)(beng)。對(dui)于ZJS三級(ji)(ji)機組而(er)言(yan),主(zhu)泵(beng)(beng)級(ji)(ji)的前(qian)級(ji)(ji)泵(beng)(beng)是中間(jian)(jian)級(ji)(ji),中間(jian)(jian)級(ji)(ji)的前(qian)級(ji)(ji)泵(beng)(beng)為(wei)雙級(ji)(ji)水(shui)環(huan)泵(beng)(beng)。對(dui)于JZJX二級(ji)(ji)機組而(er)言(yan),主(zhu)泵(beng)(beng)級(ji)(ji)的前(qian)級(ji)(ji)泵(beng)(beng)即為(wei)雙級(ji)(ji)水(shui)環(huan)泵(beng)(beng)。
各級(ji)(ji)真(zhen)空(kong)泵(beng)之間抽(chou)速(su)比(bi)(后級(ji)(ji)泵(beng)抽(chou)速(su)與前(qian)級(ji)(ji)泵(beng)抽(chou)速(su)相比(bi))要符合一(yi)定(ding)的(de)(de)比(bi)例。考慮到在高(gao)抽(chou)速(su)比(bi)下前(qian)級(ji)(ji)泵(beng)配用(yong)功率和抽(chou)排氣(qi)能(neng)力的(de)(de)不足對后級(ji)(ji)真(zhen)空(kong)泵(beng)的(de)(de)不利影響。一(yi)般抽(chou)速(su)比(bi)不宜大于(yu)3,而(er)以取抽(chou)速(su)比(bi)為2左右(you)為佳。
由于羅(luo)茨(ci)真(zhen)(zhen)空(kong)泵具有優良的抽氣特(te)性(在(zai)(zai)低壓下(xia)具有大(da)(da)的抽速(su)),且(qie)在(zai)(zai)羅(luo)茨(ci)真(zhen)(zhen)空(kong)泵的極(ji)限真(zhen)(zhen)空(kong)范圍(wei)內使用羅(luo)茨(ci)真(zhen)(zhen)空(kong)泵作為(wei)后級(ji)(ji)泵,總能(neng)比前(qian)級(ji)(ji)真(zhen)(zhen)空(kong)泵提高個數量級(ji)(ji)的真(zhen)(zhen)空(kong)度(如前(qian)級(ji)(ji)真(zhen)(zhen)空(kong)度為(wei)100Pa那未使用羅(luo)茨(ci)真(zhen)(zhen)空(kong)泵作后級(ji)(ji)泵,就可提高到10Pa,余類(lei)推(tui))。由于羅(luo)茨(ci)真(zhen)(zhen)空(kong)泵的轉(zhuan)子與轉(zhuan)子,轉(zhuan)子與泵腔均無機(ji)械接觸,無須潤滑(hua),故其(qi)功率損耗就明(ming)顯小于具有相同抽速(su)的其(qi)它(ta)類(lei)型機(ji)械真(zhen)(zhen)空(kong)泵。又由于JZJS型機(ji)組配備雙級(ji)(ji)水環泵作為(wei)其(qi)前(qian)級(ji)(ji)泵,所以(yi)對抽除具有定腐蝕(shi)性,含水蒸汽量大(da)(da)的工(gong)業流程特(te)別適宜。
