Midziyo inogona kudzinga gasi kubva mumudziyo wakavharwa kana kuchengetedza huwandu hwemamorekuru egasi mumudziyo ichidzikira inowanzonzi vacuum inowana michina kana vacuum pombi.Zvinoenderana nemusimboti wekushanda wevacuum pombi, pombi dzevacuum dzinogona kukamurwa kuita mhando mbiri, dzinoti pombi dzekufambisa gasi uye pombi dzekuteya gasi.
Mapombi ekufambisa gasi
Pombi yekufambisa gasi ipombi yevacuum inobvumira kusveta kunoramba kuchienderera uye kubuda kwemagasi nekuda kwekupomba.
1) Variable vhoriyamu vacuum pombi
Iyo inoshanduka vhoriyamu vacuum pombi ipombi yekutsvaira inoshandisa shanduko ye cyclic yevhoriyamu yekamuri yepombi kupedzisa kusveta nekuburitsa.Iyo gasi inomanikidzwa isati yabuda uye kune marudzi maviri emapombi: kudzorera uye kutenderera.
Iyo rotary vacuum pombi mutafura iri pamusoro inowanika zvakare mumhando dzinotevera:
Iwo maoiri-akavharirwa vacuum pombi ari patafura iri pamusoro anogona kukamurwazve kuita marudzi mashanu zvichienderana nemaitiro avo anotevera:
2) Momentum kutamisa pombi
Iri rudzi rwepombi rinotsamira pamhanyiro inotenderedza vanes kana majeti ekumhanya-mhanya kuendesa simba kune gasi kana gasi mamorekuru kuitira kuti gasi rirambe richitamiswa kubva mukupinda kuenda kunobuda pombi.Vanogona kugoverwa mumhando dzinotevera.
| Type | Tsanangudzo | Classification |
| Molecular vacuum pombi | Iyo pombi yevacuum inoshandisa rotor inotenderera ichimhanya zvakanyanya kuendesa simba kumamorekuru egasi kuamanikidza uye kuapedza. | Kudhonza molecular pombi:mamorekuru egasi anowedzera simba nekudhumhana nerotor ichifamba nekumhanya kwazvo uye inotumirwa kunobuditsa, uye naizvozvo ipombi yekufambisa. |
| Turbomolecular pombi:Mapombi ane slotted discs kana rotor ane vanes anotenderera pakati pe stator discs (kana stator blades).Rotor circumference ine high linear velocity.Iyi mhando yepombi inowanzoshanda mune imwe molecular flow state | ||
| Composite molecular pump: Iyo composite molecular vacuum pombi inosanganisa maviri marudzi emolekemu pombi munhevedzano, rudzi rweturbine uye rudzi rwekudhonza. | ||
| Jet vacuum pombi | Iyo pombi yekufambisa inomhanyisa inoshandisa yakakwira velocity jet inogadzirwa nekudonha kwekumanikidza kweVenturi kuendesa gasi kunzvimbo yekubuda uye inokodzera kushanda mune viscous uye shanduko yekuyerera mamiriro. | Liquid jet vacuum pombi:jet vacuum pombi dzine mvura (kazhinji mvura) senzira yekushanda |
| Gasi jet vacuum pombi:jet vacuum pombi dzinoshandisa asiri-condensable magasi sekushanda svikiro | ||
| vapor jet vacuum pombi:jet vacuum pombi dzinoshandisa mhute (mvura, mafuta kana mercury mhute zvichingodaro) sepakati pekushanda. | ||
| Diffusion pumps | Jet vacuum pombi ine yakaderera-pressure, yakakwirira-speed vapor stream (mhute yakaita seoiri kana mercury) senzira yekushanda.Iwo mamorekuru egasi anopararira mumhepo yemhepo uye anotumirwa kunobuda.Density yemamorekuru egasi mujeti inogara yakadzikira uye pombi inokodzera kushanda mune imwe molecular flow state. | Kuzvichenura pombi yekuparadzira:pombi yekuparadzira mafuta umo tsvina inoputika mumvura yepombi inoendeswa kunzvimbo yekubuda nemichina yakakosha isingadzoke kubhailer. |
| Fractionated diffusion pump:Iyi pombi ine chidimbu chechikamu kuitira kuti mhute yemvura inoshanda ine mhute yakaderera ipinde mumuromo webasa guru rekutsvaira, nepo mhute yemvura inoshanda ine mhute yakakwira ichipinda mumuromo webasa rakaderera, iri mafuta ane nhanho dzakawanda. pombi yekuparadzira | ||
| Diffusion jet pombi | Iyo imwe chete kana yakawanda-nhanho muromo ine hunhu hwepombi yekuparadzira uye imwe kana yakawanda-nhanho muromo ine maitiro ejet vacuum pombi munhevedzano kugadzira pombi yekufambisa.Pombi inosimudzira mafuta ndeyemhando iyi | Hapana |
| Ion kutamisa pombi | Iyo pombi yekumhanyisa inoendesa iyo ionised gasi kune yekubuda pasi pechiito chemagetsi kana munda wemagetsi. | Hapana |
Mapombi ekuteya gasi
Mhando yepombi iyi pombi yevacuum umo mamorekuru egasi anoshambadzirwa kana kupfupikiswa mukati mepombi, nokudaro kuderedza huwandu hwemamorekuru egasi mumudziyo uye nekuzadzisa chinangwa chekupomba, kune marudzi akati wandei.
Sezvo vacuum kunyorera mumunda wekugadzira uye kutsvagisa kwesainzi kunoda kuwanda kwakakura kwekumanikidza kwekushandisa, mazhinji acho anoda akati wandei mapombi ekugadzira vacuum yekupomba sisitimu yekupomba pamwe chete kuitira kuti isangane nezvinodiwa zvekugadzira uye maitiro ekutsvagisa kwesainzi. kune dzimwe nguva apo marudzi akasiyana-siyana emapombi ekuputira anoshandiswa pakupomba.Kuti ufambise izvi, zvinodikanwa kuti uzive zvakadzama kupatsanurwa kwemapombi aya.
