概述
JZJS系列羅(luo)茨(ci)-水(shui)(shui)環(huan)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)機(ji)組(zu),是以羅(luo)茨(ci)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng),(又名(ming)羅(luo)茨(ci)增(zeng)壓泵(beng))為(wei)(wei)主泵(beng),以雙級(ji)水(shui)(shui)環(huan)式(shi)(shi)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)為(wei)(wei)前(qian)級(ji)泵(beng)通過(guo)電(dian)接點真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)表(biao)電(dian)接點壓力表(biao)來實現羅(luo)茨(ci)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)水(shui)(shui)環(huan)式(shi)(shi)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)的(de)(de)自動(dong)啟閉,自動(dong)保(bao)護(hu)及(ji)整(zheng)套機(ji)組(zu)的(de)(de)安全保(bao)護(hu)的(de)(de)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)獲得設(she)備它(ta)除了具有一般羅(luo)茨(ci)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)機(ji)組(zu)的(de)(de)某些特點外,由(you)于采用水(shui)(shui)環(huan)式(shi)(shi)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)作為(wei)(wei)前(qian)級(ji)泵(beng),所以它(ta)特別適(shi)用于抽(chou)除含有較多水(shui)(shui)蒸汽及(ji)有一定腐蝕(shi)性氣體(ti)的(de)(de)工(gong)(gong)(gong)業(ye)流程中,例如干燥、脫水(shui)(shui)、蒸發、蒸餾、結晶等(deng)工(gong)(gong)(gong)藝流程由(you)于水(shui)(shui)環(huan)式(shi)(shi)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)的(de)(de)極限真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)遠比油封機(ji)械泵(beng)低,所以用水(shui)(shui)環(huan)式(shi)(shi)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)作前(qian)級(ji)泵(beng)的(de)(de)羅(luo)茨(ci)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)水(shui)(shui)環(huan)泵(beng)機(ji)組(zu)的(de)(de)極限真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong),比用油封機(ji)械泵(beng)作前(qian)級(ji)泵(beng)的(de)(de)羅(luo)茨(ci)真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)泵(beng)油封機(ji)械泵(beng)機(ji)組(zu)的(de)(de)極限真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)低。本型號三級(ji)機(ji)組(zu)的(de)(de)極限真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)為(wei)(wei)25Pa,二(er)級(ji)機(ji)組(zu)的(de)(de)極限真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)為(wei)(wei)400Pa,但(dan)這(zhe)樣的(de)(de)極限真(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)對(dui)上述工(gong)(gong)(gong)業(ye)流程的(de)(de)要求已完(wan)全可以滿足了。
工作原理及結構特點
JZJS型(xing)機(ji)組(zu)主要是(shi)由(you)兩大部分(fen)組(zu)成(cheng)。即泵(beng)(beng)(beng)部分(fen)(抽氣部分(fen))和電源控制部分(fen)。J乙JS三級(ji)(ji)機(ji)組(zu)的(de)泵(beng)(beng)(beng)部分(fen)是(shi)由(you)兩臺羅(luo)茨真(zhen)空(kong)泵(beng)(beng)(beng)和一(yi)臺雙級(ji)(ji)水(shui)環式真(zhen)空(kong)泵(beng)(beng)(beng)三級(ji)(ji)串聯(lian)而成(cheng),其中雙級(ji)(ji)水(shui)環泵(beng)(beng)(beng)叫做(zuo)前級(ji)(ji)泵(beng)(beng)(beng),與被抽容器相聯(lian)的(de)羅(luo)茨真(zhen)空(kong)泵(beng)(beng)(beng)叫做(zuo)主泵(beng)(beng)(beng)級(ji)(ji),與前級(ji)(ji)和主泵(beng)(beng)(beng)級(ji)(ji)相聯(lian)的(de)一(yi)級(ji)(ji)羅(luo)茨真(zhen)空(kong)泵(beng)(beng)(beng)叫做(zuo)中間級(ji)(ji),如果去掉中間級(ji)(ji)羅(luo)茨真(zhen)空(kong)泵(beng)(beng)(beng),就構成(cheng)JZJS二(er)級(ji)(ji)機(ji)組(zu)。三級(ji)(ji)機(ji)組(zu)的(de)極限真(zhen)空(kong)可比二(er)級(ji)(ji)機(ji)組(zu)的(de)極限真(zhen)空(kong)提高一(yi)個數量級(ji)(ji)而進入25Pa或更高。
由于(yu)普通型羅茨真空泵(beng)(beng)不能在(zai)大氣(qi)下起動(dong),故須在(zai)其排氣(qi)端預先抽成真空,然后再起動(dong),所以在(zai)羅茨真空泵(beng)(beng)出(chu)口須配備前(qian)(qian)級(ji)(ji)(ji)真空泵(beng)(beng)(簡稱前(qian)(qian)級(ji)(ji)(ji)泵(beng)(beng))作為(wei)預抽泵(beng)(beng)。對于(yu)ZJS三(san)級(ji)(ji)(ji)機組(zu)而(er)言(yan),主泵(beng)(beng)級(ji)(ji)(ji)的(de)前(qian)(qian)級(ji)(ji)(ji)泵(beng)(beng)是中間級(ji)(ji)(ji),中間級(ji)(ji)(ji)的(de)前(qian)(qian)級(ji)(ji)(ji)泵(beng)(beng)為(wei)雙級(ji)(ji)(ji)水環泵(beng)(beng)。對于(yu)JZJX二級(ji)(ji)(ji)機組(zu)而(er)言(yan),主泵(beng)(beng)級(ji)(ji)(ji)的(de)前(qian)(qian)級(ji)(ji)(ji)泵(beng)(beng)即為(wei)雙級(ji)(ji)(ji)水環泵(beng)(beng)。
各級真空泵(beng)之間抽速(su)(su)比(bi)(bi)(后級泵(beng)抽速(su)(su)與前(qian)級泵(beng)抽速(su)(su)相(xiang)比(bi)(bi))要符合一定(ding)的(de)比(bi)(bi)例。考慮(lv)到在高抽速(su)(su)比(bi)(bi)下前(qian)級泵(beng)配用功率和抽排氣能力的(de)不足對(dui)后級真空泵(beng)的(de)不利影響。一般(ban)抽速(su)(su)比(bi)(bi)不宜大于3,而以(yi)取抽速(su)(su)比(bi)(bi)為(wei)2左右為(wei)佳(jia)。
由(you)于羅(luo)茨真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)具有(you)(you)優(you)良的(de)(de)抽(chou)氣特性(在低壓下具有(you)(you)大的(de)(de)抽(chou)速),且在羅(luo)茨真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)極(ji)限真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)范圍內使用羅(luo)茨真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)作(zuo)為后級(ji)(ji)泵(beng)(beng)(beng),總能比(bi)前級(ji)(ji)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)提高(gao)個數(shu)量級(ji)(ji)的(de)(de)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)度(如前級(ji)(ji)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)度為100Pa那未使用羅(luo)茨真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)作(zuo)后級(ji)(ji)泵(beng)(beng)(beng),就可提高(gao)到10Pa,余(yu)類推)。由(you)于羅(luo)茨真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)轉子(zi)與(yu)轉子(zi),轉子(zi)與(yu)泵(beng)(beng)(beng)腔均無機(ji)械(xie)接觸(chu),無須潤滑(hua),故其(qi)功率損(sun)耗(hao)就明顯小(xiao)于具有(you)(you)相同(tong)抽(chou)速的(de)(de)其(qi)它類型機(ji)械(xie)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)。又由(you)于JZJS型機(ji)組(zu)配(pei)備(bei)雙級(ji)(ji)水(shui)環泵(beng)(beng)(beng)作(zuo)為其(qi)前級(ji)(ji)泵(beng)(beng)(beng),所以對(dui)抽(chou)除(chu)具有(you)(you)定腐蝕性,含水(shui)蒸汽(qi)量大的(de)(de)工業流程特別適(shi)宜。
