Isimiso Esiyisisekelo
Ukusebenza kokumpompa kochungechunge lwe-JRP Roots kwenziwe ngamarotha amabili anomumo ongu-'8' egumbini lokumpompa elizungeza izinhlangothi eziphambene. Ngesilinganiso sokushayela esingu-1: 1, ama-rotor amabili ahlala ezivalela ngaphandle kokuthintana kanye negumbi. Izikhala phakathi kwezingxenye ezinyakazayo zincane ngokwanele ukuvala ohlangothini lwe-exhaust kanye nohlangothi lokuthatha ekugelezeni kwe-visous nokugeleza kwamangqamuzana, ukuze kuzuzwe inhloso yokumpompa igesi ekamelweni.
Lapho ama-rotors ethola ku-1 no-2 ekamelweni, umthamo we-air inlet uzokwanda. Uma ama-rotor ethola ku-3 ekamelweni, ingxenye yevolumu yomoya izovinjelwa ngaphandle kwe-air inlet. Uma ama-rotor ethola ku-4, le volumu izovuleka ukuze ikhiphe. Lapho ama-rotor eqhubeka, umoya uzophuma nge-outlet yomoya. Ama-rotor azozungeza ngaphezu kwamakhore amabili kanye ngalinye lizungeza.
Umehluko wengcindezi phakathi kohlangothi lokungena kanye nohlangothi oluphumayo lwepompo yezimpande unomkhawulo. Iphampu yezimpande zochungechunge lwe-JRP isebenzisa i-valve yokudlula. Lapho inani lomehluko wengcindezi lifinyelela esibalweni esithile, i-valve yokudlula ivuleka ngokuzenzakalelayo.Omunye umthamo womoya osuka ohlangothini lokuphuma ugeleza uye ohlangothini olungemuva lohlangothi lokungena ngokusebenzisa i-valve ye-bypass ne-reverse passage, okunciphisa umthwalo wokusebenza wephampu yezimpande kanye nepompo yesiteji sangaphambili kakhulu esimweni somehluko omkhulu wengcindezi. Khonamanjalo, ngenxa yomsebenzi wokukhipha lapho kuvulwa i-valve yokudlula, yenza isiqiniseko sokuthi iphampu yevacuum yochungechunge lwe-JRP kanye nephampu yesiteji sangaphambili iqala ngesikhathi esifanayo ukugwema ukugcwala kwakho kokubili.
Iphampu yezimpande kufanele isetshenzwe njengeyunithi yepompo kanye nepompo yesiteji sangaphambili (njengepompo ye-vane ezungezayo, iphampu yevalve yesilayidi kanye nephampu yeringithoni ewuketshezi). Uma kudingeka ukuthi kufinyelele ku-vacuum degree ephakeme, amasethi amabili amaphampu ezimpande angaxhunywa ukuze asebenze njengeyunithi yephampu yezimpande zesiteji ezintathu.

Izici
1. Kukhona i-zero friction phakathi kwama-rotors, futhi phakathi kwe-rotor ne-pump chamber, ngakho-ke asikho isidingo samafutha okugcoba. Ngenxa yalokho, iphampu yethu ingagwema ukungcoliswa kukawoyela ohlelweni lwe-vacuum.
2. Isakhiwo esihlangene, futhi kulula ukusifaka sivundlile noma sime mpo.
3. Ibhalansi eguquguqukayo enhle, ukugijima okuzinzile, ukudlidliza okuncane nomsindo ophansi.
4. Ingakwazi ukupompa igesi engacondensable.
5. Iqale ngokushesha futhi ingafinyelela ingcindezi enkulu ngesikhathi esifushane.
6. Amandla amancane kanye nezindleko zokulungisa eziphansi zokusebenza.
7. Inani le-bypass kupompo yezimpande lingajabulela umphumela wokuvikela ukugcwala okuzenzakalelayo, ukuze umsebenzi uphephe futhi uthembeke.

Amabanga wohlelo lokusebenza
1. I-vacuum drying kanye nokukhulelwa
2. i-vacuum degass
3. Vacuum ngaphambi kokukhipha
4. ukuqeda igesi
5. ngezinqubo ze-vacuum distillation, i-vacuum concentration kanye ne-vacuum drying embonini yamakhemikhali, imithi, ukudla nesiphuzo, imboni elula kanye nemboni yendwangu.
