Pombi yeRoots inogadzira vacuum ichishandisa maviri anotenderedza anotenderera, ane rotor. Marotor aya anoteya gasi painopinza uye oitakura achiyambuka imba yepombi pasina kudzvanywa kwemukati. Uku kuenderera mberi, kumhanyisa-kumhanya kwemamorekuru egasi kunoderedza kudzvanywa, kuwana vacuums yakaderera se10⁻⁵ mbar nekutsigirwa kwakakodzera. Musika wepasi rose vacuum pombi kukura kwakasimba kunoratidza kukosha kwayo.
Mazhinji masekete akakosha anovimba neMidzi vacuum pombi, kusanganisira:
• Semiconductor Indasitiri: Yemaitiro akaita seyakaonda-firimu deposition uye etching.
• Chemical Indasitiri: Muzvikumbiro zvakadai se distillation uye kuomesa.
• Pharmaceutical Indasitiri: Yevacuum filtration uye nechando-kuomesa.
Kushanda Kwemukati Kwepombi Yekutsvaira Midzi
A Roots vacuum pombi inoshanda zviri nyore asi inoshanda zvakanyanya. Muchina waro wemukati unofambisa gasi kubva painopinza kuenda painobuda pasina kuimanikidza mukati mepombi kamuri. Iyi nzira inotsamira pakufamba kwakawiriraniswa kwezvikamu zvakakosha zvakati wandei zvinoshanda mukuwirirana kwakakwana.
Iyo ina-Nhanho Operating Cycle
Kupomba kunoitika mukutenderera, nhanho ina inodzokorodza zviuru zvenguva paminiti. Rotor dzemazuva ano dzinogona kutenderera nekumhanya kubva pa3,000 kusvika 6,000 RPM. Kumhanya kukuru uku kunoita kuti pombi ifambe mavhoriyamu makuru egasi nekukurumidza.
Kudya: Sezvo marotor maviri akakomberedzwa anotenderera akatarisana, homwe yenzvimbo inovhurika panopinzwa pombi. Gasi kubva mukamuri yekuvhaira inoyerera ichipinda ichi chinowedzera vhoriyamu.
Kuzviparadzanisa nevamwe: Iyo muromo werotor lobe inopfuura chiteshi chekupinda. Ichi chiito chinoteya huwandu hwegasi pakati pe rotor uye imba yepombi.
Transfer: Homwe yakavharirwa yegasi inobva yatsvairwa mukati meimba yakananga kunobuditsa. Chinhu chakakosha cheRoots vacuum pombi ndechekuti haidzvanyiriri gasi iri panguva yekufambisa. Kushanda uku kusingabatanidzi, kusina mafuta kunoita kuti isanzwe kune hupfu hushoma kana mhute yemvura.
Exhaust: Iyo rotor inoramba ichitendeuka, ichiisa pachena homwe yegesi kuchiteshi chekubuda. Iyo gasi inobva yawedzera kupinda mumutsara wekutsvaira, apo pombi inotsigira inoibvisa kubva muhurongwa. Kutenderera uku kunodzokorora, kuenderera mberi nekufambisa gasi kubva pakupinza kuenda kune yekubuda uye nekudzikisa kudzvanywa kwehurongwa.
Cherechedzo: Kunyange ichinyatsoshanda pamagasi mazhinji, kugona kwepombi yeRoots kwakadzikira pamagasi akareruka sehydrogen kana achienzaniswa nemamwe marudzi epombi.
Zvikamu Zvikuru uye Mabasa Azvo
Kuita kwakavimbika kwepombi yeRoots kunoenderana neashoma akakosha einjiniya akakwenenzverwa nepamusoro.
Rotor: Pombi ine marotor maviri akavharirana, ane lobed (kazhinji akaumbwa semufananidzo-sere). Chimiro, kana chimiro, cheaya lobes anokanganisa zvakananga kuita. Madhizaini akasiyana anopa kutengeserana pakati pekumhanya kwekupomba uye kugona. Helical rotors, semuenzaniso, inobatsira kuderedza kudzvanywa uye ruzha rwekuita.
| Rotor Profile Type | Kupomba Speed Advantage | Volume Utilization Rate |
|---|---|---|
| Novel elliptical | 1.5 nguva yakakwira kupfuura elliptical yepamusoro | High |
| Pamusoro elliptical | Standard performance | Inosvika 55% |
Dzimba (Casing): Uyu ndiwo muviri wekunze unovhara rotor. Yakavakwa kuti imirire misiyano yekumanikidza pakati pevacuum system nemhepo. Izvo zvinoshandiswa paimba uye rotor zvinoenderana nezvinodiwa zvechikumbiro zvekurarisa, simba uye mutengo.
| Material | Makomborero Anokosha | Common Applications |
|---|---|---|
| Cast Iron | Simba rakakwirira, kupfeka kwakanaka kuramba, kudhura-zvinobudirira. | General maindasitiri, makemikari, uye kugadzira chikafu. |
| Simbi isina ngura | Yakanakisa corrosion resistance, hutsanana zvinhu. | Pharmaceutical, semiconductor, uye mishonga yekurapa. |
| Aluminium Alloy | Chiremba, chakanaka chekushisa conductivity. | Aerospace, mota, uye inotakurika pombi masisitimu. |
Nguva Yemagiya: Inowanikwa kunze kwekamuri yekupomba, magiya enguva akakosha. Vanowiriranisa ma rotor maviri, vachiona kuti vanotenderera munzira dzakatarisana vasina kumbobata mumwe nemumwe kana imba. Uku kuwiriranisa kwakakosha pakusabatika kwepombi.
Shaft Seals: Zvisimbiso zvinodzivirira mweya kuti usapinda mukamuri yekutsvaira uye kumisa mafuta ekuzora kusvibisa maitiro. Kusarudzwa kwechisimbiso kunoenderana neinodiwa vacuum level uye kushandiswa.
| Chisimbiso Type | Mechanism | Best For |
|---|---|---|
| Labyrinth Seal | Inoshandisa nzira yakaoma kumisa kuyerera; hapana kuonana. | High-speed applications panodiwa zero kupfeka. |
| Mechanical Chisimbiso | Inoshandisa zviso zviviri zvakakwenenzverwa, zvakatakurwa muchirimo. | High-pressure, high-temperature, uye yakaderera-leakage zvinodiwa. |
| Magnetic Fluid Chisimbiso | Inoshandisa magineti fluid kugadzira chinovharira chakakwana. | High-vacuum application inoda zero leakage. |
Kukosha Kwezvichemo Zvakakwana
Izwi rekuti "clearance" rinoreva diki, akaverengerwa mukaha pakati pemarota uye pakati pemarota neimba. Aya mapeji ndiwo akavanzika ekubudirira kwepombi. Vanobvumira rotor kutenderera nekumhanya kwakanyanya pasina kukwesha, izvo zvinopa akawanda mabhenefiti:
Kurumidza kutanga
Kushandisa simba kwakaderera
High kupomba kumhanya
Kuderera kwekushanda nekugadzirisa mari
Nekudaro, izvi zvibvumirano zvinofanirwa kutariswa zvakakwana. Panguva yekushanda, pombi inogadzira kupisa. Kupisa uku kunoita kuti zvikamu zvesimbi zvikure, chirongwa chinozivikanwa sekuwedzera kwekupisa. Sezvo rotor uye dzimba dzichiwedzera, zvibvumirano pakati pavo zvinoderera.
Yambiro: Kana zvibvumirano zvikava diki zvakanyanya nekuda kwekuwedzera kwekupisa kana kusangana kwakashata, ma rotor anogona kusangana nemumwe kana imba. Izvi zvinotungamira mukukwesha, kukuvadzwa kwechikamu, kuwedzera mota mutoro, uye inogona kubata pombi. Sezvineiwo, kucheneswa kwakakurisa kunobvumira gasi kudonha kumashure kubva pakubuda kuenda kunopinza, izvo zvinoderedza zvakanyanya kushanda kwepombi.
Injiniya yakakodzera uye kusarudzwa kwezvinhu kunovimbisa kuti Roots vacuum pombi inochengetedza zvakakwana kubvumidzwa mukati meseji yekushandisa kwayo tembiricha, ichiunza yakavimbika uye inoshanda kuita.
Kugadziriswa Kwehurongwa: Kutsigira vs. Multi-Stage Pumps
Pombi yeRoots ine simba guru, asi haigone kushanda yega. Inoda imwe gadziriro yegadziriro kuti isvike pakukwanisa kwayo kuzere. Iyo pombi inofambisa gasi zvakanaka asi haiidzvanyiriri zvakakwana kuti ibudise yakananga mumhepo. Ichi chinogumira chinoda kushandiswa kwepombi yekutsigira kana kurongeka kwematanho akawanda.
Sei Kutsigira Pombi kuchidikanwa
Pombi yeRoots inoda pombi inotsigira kuti ibate kubuda kwayo. Pombi inotsigira inobatana nekubuda kwepombi yeMidzi. Inotora gasi rakatamiswa uye rinoimanikidza kumhepo yemhepo, kupedzisa nzira yekubuda nayo. Kudyidzana uku kunobvumira sisitimu kuti iwane zvakadzika vacuums zvinobudirira. Sarudzo yepombi inotsigira zvinoenderana neiyo chaiyo application uye inodiwa vacuum level.
Waizviziva Here? Iyo pombi inotsigira inonziwo pombi yekutanga nekuti inoita basa rekupedzisira rekubvisa gasi kubva muhurongwa.
Mhando dzakajairika dzemapombi ekutsigira dzinosanganisira:
Matanho maviri e rotary vane pombi
Mafuta-akavharwa mechanical pombi
Maviri-nhanho inotsvedza vharafu mechanical pombi
Liquid ring vacuum pombi
Iyo Multi-Stage Mapombi Anoshanda
Kune maapplication arikuda kuderera zvakanyanya, mainjiniya anobatanidza akawanda pombi munhevedzano. Izvi zvinogadzira akawanda-nhanho Roots Vacuum Pump system. Mukugadzirisa uku, kubuda kwepombi yekutanga kunodyisa mukupinda kwechipiri, zvichingodaro. Nhanho imwe neimwe inotevedzana inoderedza dzvinyiriro zvakare. Pombi yekupedzisira inotsigira ichiri kudikanwa kumagumo echeni kuti ibudise gasi kumhepo.
Aya masisitimu ane simba akakosha kune epamusoro-tech uye anoda maindasitiri. Zvikumbiro zvakakosha zvinosanganisira:
Semiconductor Manufacturing: Yemaitiro akaita seChemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), uye etching.
Aerospace: Muchadenga simulation makamuri uye chikamu chekuyedza.
New Energy: Yekugadzira solar panel nemabhatiri.
Iyo Roots vacuum pombi inokwenenzvera pakufambiswa kwegasi inomhanya pane kudzvanyirira mukati. Yayo yakapfava, isiri-yekubata dhizaini inogadzira ine simba booster kune yakachena, yakakwirira-kuburikidza maapplication. Mapombi emazuva ano ano batanidza mota dzinoshanda nesimba uye akangwara masensa, achisundidzira kuita basa zvakatonyanya kune anoda maindasitiri anoda akavimbika uye anoshanda vacuum masisitimu.
