Basic Mabda'a
hawlgalka Maskhiin Roots taxane JRP dhibta laba '8' rotors qaabeeya ee ku listo qolkii qoqobada jiho ka soo hor jeedda. Iyada oo ratio drive ee 1: 1, laba rotors joogto xir Naftooda aan midba midka kale iyo qolkii oo gayeysiin kara. Farqiyada u dhexeeya qaybaha dhaqaajin karo waa cidhiidhi ah oo ku filan in la shaabadeeyo ka dhanka ah kooxda qaaca iyo kooxda qaadashada in socodka visous iyo socodka kelli, si ay si ay u gaaraan ujeedada shubaya gaas ee qolkii.
Marka rotors ka helaan at 1 iyo 2 ee qolkii, mugga tubada hawada u kordhin doonaa. Marka rotors ku helaan 3 qolladdii, qayb ka mid ah mugga hawada la xakameeyo soo baxay tan iyo gacanka hawada. Marka rotors ka helaan 4, mugga this furi doonaa inay ka hadlaan fekerkooda. Marka rotors sii, hawada u guto doonaa outlet hawada. Rotors rotors doonaa in ka badan laba coures isku bedbedeli doono kasta hal jeer.
Farqiga u dhaxeeya cadaadiska dhinaca tubada iyo kooxda outlet xididdadiisa bamka waa kooban. JRP xididdada taxane bamka wuxuu qaadanayaa ku biiyaha isku tallaalidda ah. Marka qiimaha kala duwan yihiin cadaadis gaaro qaabkii gaar ah, waalka isku tallaalidda furo mugga hawada automatically.Some dhankeeda outlet ku qubanayo in jihada dambe ee kooxda tubada dhex biiyaha isku tallaalidda iyo beddeli marinka, oo la yareeyo load ka hawl xididdadiisa bamka iyo bamka hore-yada si weyn in xaaladda farqiga cadaadis sare. Dhanka kale, ay sabab u tahay shaqo ee dajinta markii biiyaha isku tallaalidda ka furmay, waxa ay taasi loo hubiyo in bamka JRP taxane vacuum iyo hore-yada bamka bilowday isku mar si looga fogaado dollar ee labada iyaga ka mid ah.
The bamka xididdada waa in la wada shaqeeyeen sidii unit bamka la bamka hore-yada (sida qoqobada bamka Vane, simbiriirixan bamka waalka iyo dareere bamka giraanta). Haddii loo baahan yahay si ay u gaaraan in ay degree vacuum sare, laba nooc oo bambooyin xididada loogu xidhi karaa in ay ka shaqeeyaan sidii unit xididdada bamka saddex stage ah.

Astaamaha
1. Waxaa jira eber khilaaf u dhexeeya rotors, sidoo kale inta u dhaxaysa rotor iyo qolladdii bamka, sidaa darteed looma baahna oo saliid cabbeeyo. Sidaas awgeed, our bamka looga fogaado kartaa wasakhaynta saliid on nidaamka vacuum ah.
2. Dhismaha Compact, oo ay fududahay in si gudban ama vertical rakibi.
3. dheelitirka firfircoon Good, orodka deggan, gariirka yar iyo sanqadh yar yahay.
4. lisidda karaa gaaska non-condensable.
5. Quick bilaabay iyo gaari karo cadaadis darafkeeda in wakhti yar oo gaaban.
6. kharashka xoog iyo dayactirka hawlgalka hooseeyo Small.
7. Qiimaha isku tallaalidda on xididdada bamka ku raaxaysan karaan saamayn ilaalinta dollar ah si toos ah, sidaas darteed in howlgalka uu noqon doonaa mid ammaan ah oo lagu kalsoonaan karo.
