水(shui)(shui)環式(shi)(shi)(shi)(shi)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)已(yi)正(zheng)確組合(he)。由(you)于水(shui)(shui)環型真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)具有(you)(you)選(xuan)擇(ze)性泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)送(song)(song)功(gong)能(neng)，因(yin)(yin)此有(you)(you)時不能(neng)使用(yong)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)來滿(man)足(zu)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)送(song)(song)要(yao)求(qiu)。需要(yao)將多個泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)組合(he)在一起以相互補充，以滿(man)足(zu)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)送(song)(song)要(yao)求(qiu)。例(li)如(ru)，鈦(tai)可(ke)以提高泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)對氫氣(qi)(qi)(qi)的(de)(de)(de)(de)(de)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)浦速(su)(su)度(du)(du)，但(dan)(dan)不能(neng)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)浦氦氣(qi)(qi)(qi)，而(er)三(san)極(ji)濺(jian)射離子(zi)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)(或兩極(ji)非(fei)對稱陰極(ji)濺(jian)射離子(zi)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng))對于氬(ya)氣(qi)(qi)(qi)則(ze)具有(you)(you)一定的(de)(de)(de)(de)(de)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)浦速(su)(su)度(du)(du)。結(jie)合(he)起來，真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)設備將獲得更好的(de)(de)(de)(de)(de)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)度(du)(du)。另外，某些(xie)水(shui)(shui)環型真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)不能(neng)在大(da)氣(qi)(qi)(qi)壓(ya)(ya)(ya)(ya)(ya)下(xia)運行，需要(yao)預真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)。一些(xie)水(shui)(shui)環型真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)(de)(de)出口壓(ya)(ya)(ya)(ya)(ya)力(li)(li)(li)(li)(li)低于大(da)氣(qi)(qi)(qi)壓(ya)(ya)(ya)(ya)(ya)，并(bing)(bing)且需要(yao)前級(ji)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)，因(yin)(yin)此需要(yao)結(jie)合(he)使用(yong)。 5、要(yao)求(qiu)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)設備造成油(you)污(wu)染。如(ru)果設備嚴重要(yao)求(qiu)無(wu)油(you)，則(ze)應(ying)(ying)(ying)(ying)選(xuan)擇(ze)各種無(wu)油(you)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)，例(li)如(ru)...
