Tšebeliso ea liner ea turbocharger ea koloi ke efe?
Mosebetsi o ka sehloohong oa turbocharger ea likoloi ke ho eketsa ho kenella ha enjene, ka hona ho eketsa matla a tlhahiso le torque ea enjene, e le hore koloi e fumane matla a mangata. Ka ho khetheha, turbocharger e sebelisa matla a khase ea mosi o tsoang enjeneng ho khanna compressor, 'me e hatella moea ka har'a phaephe ea ho kenella, e eketsa bongata ba ho kenella, e nolofalletsa enjene ho chesa mafura a mangata, ka hona e eketsa tlhahiso ea matla.
Mokhoa oa ho tjhaja turbocharger
Turbocharger e entsoe haholo-holo ka likarolo tse peli: turbine le compressor. Ha enjene e sebetsa, khase ea mosi e ntšoa ka phaephe ea mosi, e sutumelletsa turbine ho potoloha. Ho potoloha ha turbine ho khanna compressor le ho hatella moea ka phaepheng ea mosi, ka hona ho eketsa khatello ea mosi le ho ntlafatsa bokhoni ba ho tuka le tlhahiso ea matla.
Melemo le mathata a li-turbocharger
Melemo:
Keketseho ea tlhahiso ea matla: Li-turbocharger li khona ho eketsa ho kenella ha moea, li lumella enjene ho hlahisa matla le torque e eketsehileng bakeng sa ho falla ho tšoanang.
Moruo o ntlafetseng oa mafura: Lienjene tse nang le turbocharger li chesa hamolemo, hangata li boloka 3%-5% ea mafura, 'me li na le ts'epo e phahameng, litšobotsi tse ntle tsa ho bapisa le karabelo ea nakoana.
ikamahanya le bophahamo bo phahameng: turbocharger e ka etsa hore enjene e boloke matla a mangata a hlahisoang sebakeng se phahameng, ho rarolla bothata ba oksijene e tšesaane sebakeng se phahameng.
Mathata:
Hysteresis ea Turbine: ka lebaka la ho se sebetse hantle ha turbine le bearing e mahareng, ha khase ea mosi e eketseha ka tšohanyetso, lebelo la turbine le ke ke la eketseha hang-hang, e leng se fellang ka hysteresis ea tlhahiso ea matla.
Phello ea lebelo le tlase ha e ntle: tabeng ea lebelo le tlase kapa pherekano ea sephethephethe, phello ea turbocharger ha e bonahale, e betere le ho feta enjene e bululetsoeng ka tlhaho.
Li-turbocharger tsa likoloi li entsoe ka thepa e fapaneng e kang mabili, li-bearing, likhetla le li-impeller. Hangata mabili a etsoa ka thepa ea superalloy, joalo ka Inconel, Waspaloy, jj., ho fihlela litlhoko tsa mocheso o phahameng le khatello.
Hangata dibering di etswa ka cermet le thepa e nngwe ho ntlafatsa ho tsofala le ho hanyetsa ho bola.
Karolong ea khetla, khetla ea compressor boholo ba eona ke motsoako oa aluminium kapa motsoako oa magnesium ho fokotsa boima le ho ntlafatsa ts'ebetso, ha khetla ea turbine boholo ba eona e le tšepe e entsoeng ka .
Impeller le shaft li entsoe haholo-holo ka tšepe, haholo-holo compressor impeller hangata e sebelisa superalloy, e nang le khanyetso e ntle ea oxidation ea mocheso o phahameng, matla le khanyetso ea mafome.
Lisebelisoa tsa likarolo tse fapaneng le mesebetsi ea tsona
Sebaka sa lebili: tšebeliso ea thepa ea motsoako oa mocheso o phahameng, joalo ka Inconel, Waspaloy, jj., ho fihlela litlhoko tsa mocheso o phahameng le khatello.
bearing: hangata ho sebediswa ceramic ya tshepe le thepa e nngwe ho ntlafatsa ho tsofala le ho hanyetsa ho bola.
khetla:
Khetla ea compressor: boholo ba motsoako oa aluminium kapa motsoako oa magnesium, ho fokotsa boima le ho ntlafatsa ts'ebetso.
Khetla ea turbine : thepa ea tšepe e entsoeng haholo-holo.
li-impeller le li-shaft: boholo ba tšepe, haholo-holo li-impeller tsa compressor hangata li sebelisa superalloy, motsoako ona o na le khanyetso e ntle ea oxidation ea mocheso o phahameng, matla le khanyetso ea mafome.
Mabaka a susumetsang khetho ea thepa
Khetho ea thepa ea turbocharger e nahana haholo ka lintlha tse latelang:
Mocheso o phahameng le khatello e phahameng: mocheso o ka hare le khatello ea turbocharger li phahame, 'me ho hlokahala ho khetha thepa e nang le mocheso o motle o phahameng le khatello e phahameng.
Ho hanyetsa ho tsofala: likarolo tse hatelitsoeng li hloka ho ba le ho hanyetsa ho tsofala ho itseng ho ntlafatsa bophelo ba ts'ebeletso.
Thepa ea mechini: thepa e hloka ho ba le matla le ho tiea ho lekaneng ho fihlela litlhoko tsa ts'ebetso e potlakileng.
Haeba o batla ho tseba ho eketsehileng, tsoela pele ho bala lihlooho tse ling sebakeng sena sa marang-rang!
Ka kopo re letsetse haeba o hloka dihlahiswa tse jwalo.
Zhuo Meng Shanghai Auto Co., Ltd. e ikemiselitse ho rekisa likarolo tsa likoloi tsa MG&750 lia amoheleha ho reka.
