Tšebeliso ea mochini oa turbocharger liner ke eng
Karolo e ka sehloohong ea turbocharger ea likoloi ke ho eketsa ho kenngoa ha enjene, ka hona ho eketsa matla a tlhahiso le torque ea enjene, e le hore koloi e fumane matla a eketsehileng. Haholo-holo, turbocharger e sebelisa matla a khase e tsoang ho enjene ho khanna compressor, 'me e hatella moea ka har'a phala e kenang, e eketsa sekhahla sa ho kenella, e nolofalletsang enjene ho chesa mafura a mangata, kahoo e eketsa tlhahiso ea matla.
Kamoo turbocharger e sebetsang kateng
Turbocharger e entsoe haholo ka likarolo tse peli: turbine le compressor. Ha enjene e sebetsa, khase ea mouoane e ntšoa ka phaephe ea mosi, e sutumelletsa turbine hore e bilike. Ho potoloha ha turbine ho khanna compressor le ho hatella moea ka har'a phala e kenang, ka tsela eo ho eketsa khatello ea ho kena le ho ntlafatsa ts'ebetso ea mollo le tlhahiso ea matla.
Melemo le bofokoli ba li-turbocharger
Melemo :
Keketseho ea matla a matla : Li-Turbocharger li khona ho eketsa ho kena ha moea, ho lumella enjene ho hlahisa matla a mangata le torque bakeng sa phallo e tšoanang.
Moruo o ntlafalitsoeng oa mafura : Lienjine tse nang le turbocharged li chesa hamolemo, hangata li boloka 3% -5% ea mafura, 'me li na le ts'epo e phahameng, litšoaneleho tse tsamaellanang le karabelo ea nakoana.
ikamahanya le bophahamo bo phahameng: turbocharger e ka etsa hore enjene e boloke matla a phahameng a matla sebakeng se phahameng, ho rarolla bothata ba oksijene e tšesaane sebakeng se phahameng.
Mathata :
Turbine hysteresis : ka lebaka la inertia ea turbine le ho jara ha lipakeng, ha khase ea ho tsoa e eketseha ka tšohanyetso, lebelo la turbine le ke ke la eketseha hang-hang, e leng se etsang hore ho be le hysteresis e hlahisoang ke matla.
phello ea lebelo le tlase ha e ntle: maemong a lebelo le tlase kapa sephethephethe, phello ea turbocharger ha e hlake, le ho feta enjene e lakatsehang ka tlhaho.
Li-turbocharger tsa likoloi li entsoe ka lisebelisoa tse fapaneng joalo ka mabili, li-bearings, likhetla le li-impellers. Hangata mabili a entsoe ka thepa ea superalloy, joalo ka Inconel, Waspaloy, joalo-joalo, ho fihlela litlhoko tsa mocheso o phahameng le khatello .
Hangata li-bearings li entsoe ka cermet le lisebelisoa tse ling ho ntlafatsa moaparo le ho hanyetsa kutu.
Bakeng sa karolo ea khetla, khetla ea compressor hangata ke motsoako oa aluminium kapa alloy ea magnesium ho fokotsa boima ba 'mele le ho ntlafatsa ts'ebetso, ha khetla ea turbine hangata e le tšepe e entsoeng ka tšepe.
The impeller le shaft haholo-holo li entsoe ka tšepe, haholo-holo compressor impeller hangata e sebelisa superalloy, e nang le mocheso o phahameng oa ho hanyetsa oxidation, matla le ho hanyetsa kutu.
Lisebelisoa tsa likarolo tse fapaneng le mesebetsi ea tsona
wheel hub : ts'ebeliso ea lisebelisoa tsa alloy tse phahameng tsa mocheso, joalo ka Inconel, Waspaloy, joalo-joalo, ho fihlela litlhoko tsa mocheso o phahameng le khatello.
Bearing : hangata e ne e sebelisoa ka tšepe ea ceramic le lisebelisoa tse ling ho ntlafatsa ts'ebetso ea 'mele le ho hanyetsa ho bola.
khetla:
Compressor shell: haholo alloy ea aluminium kapa alloy ea magnesium, ho fokotsa boima ba 'mele le ho ntlafatsa ts'ebetso.
turbine shell: hangata lintho tse entsoeng ka tšepe.
li-impellers and shafts : Haholo litšepe, haholo-holo li-compressor impellers hangata li sebelisa superalloy, alloy ena e na le khanyetso e ntle haholo ea mocheso o phahameng oa oxidation, matla le ho hanyetsa kutu.
Lintlha tse susumetsang tsa khetho ea thepa
Khetho ea lisebelisoa tsa turbocharger e shebana haholo le lintlha tse latelang:
Mocheso o phahameng le khatello e phahameng : mocheso o ka hare le khatello ea turbocharger e phahame, 'me hoa hlokahala ho khetha lisebelisoa tse nang le mocheso o phahameng o phahameng le ho hanyetsa khatello e phahameng.
wear resistance : likarolo tse hatelitsoeng li hloka ho ba le khanyetso e itseng ho ntlafatsa bophelo ba ts'ebeletso.
thepa ea mochini : lisebelisoa li hloka ho ba le matla a lekaneng le ho tiea ho fihlela litlhoko tsa ts'ebetso e potlakileng.
Haeba u batla ho tseba haholoanyane, tsoela pele ho bala lingoliloeng tse ling sebakeng sena sa marang-rang!
Ka kopo, re letsetse haeba u hloka lihlahisoa tse joalo.
Zhuo Meng Shanghai Auto Co., Ltd. e ikemiselitse ho rekisa likarolo tsa koloi tsa MG&750 lia amoheloa ho reka.
