Umsebenzi we-turbocharger impeller

Umsebenzi we-i-turbocharger impeller ukusebenzisa amandla e-exhaust gas ukucindezela umoya owuthathayo, ukwandisa umthamo owuthathayo, futhi uthumele i-high-density mix gas egunjini lomlilo ukuze ivuthe ukuze kwandiswe amandla enjini okukhiphayo nokwandisa i-torque yenjini, ngaleyo ndlela kwandise amandla enjini. amandla.

Kungani i-impeller ye-turbocharger idinga ukulingana ngokuguqukayo? Ii-turbocharger empeleni umoyai-compressor okwandisa umthamo wokungena ngokucindezela umoya. Isebenzisa umthelela we-inertial we-exhaust gas ekhishwa injini ukushayelai-turbine ekamelweni le-turbine. I-turbine ishayela i-coaxial impeli, futhi i-impeller icindezela umoya othunyelwe yipayipi lokuhlunga umoya ukuze uwucindezele ku-cylinder. Lapho isivinini senjini sikhuphuka, isivinini sokukhipha igesi ephumayo kanye nesivinini se-turbine sikhuphuka ngokuhambisanayo, futhi i-impeller icindezela umoya owengeziwe ku-cylinder. Ukwanda komfutho womoya kanye nokuminyana kungashisa uphethiloli owengeziwe. Ukwenyuka okuhambisanayo kwevolumu kaphethiloli kanye nokulungiswa kwejubane lenjini kungakhuphula amandla enjini okukhiphayo.

Iinjini I-exhaust turbocharger manje isisetshenziswa kabanzi. I-turbocharger i-rotor shaft isetshenziswa endaweni yokusebenza enesivinini esikhulu, enesivinini esingama-10,000 kuya kokungaphezu kuka-200,000 amarevolution ngomzuzu. Ngaphansi kwalokhu kujikeleza kwesivinini esikhulu, ukulinganisa okunamandla kufanele kwenziwe. Ngomshini wokulinganisa oguqukayo we-turbocharger, ukutholwa kokulinganisa okunamandla kungafinyelelwa.

I-turbochargeri-impeller rotor shaft futhi umzimba ubhekisela kuma-forging anamandla anele okusebenza ukuze amelane ne-torque edluliswa umshini ohamba phambili kanye ne-torque enkulu kagesi kagesi yesekethe emfishane engazelelwe endaweni yokukhipha ijeneretha, futhi ibe nokuhamba kahle kazibuthe, okuthwala isigxobo sikazibuthe esikhulu. ijeneretha.

Ngokuthuthuka okuqhubekayo kobuchwepheshe be-automotive turbocharging, isivinini samanje sokusebenza somhlangano we-rotor we-turbocharger singafinyelela ku-60000r/min kuya ku-240000r/min. Njengomongoingxenyeye-supercharger, i-rotor ye-supercharger izodala ukudlidliza okukhulu nomsindo ngesikhathi sokuzungezisa ngesivinini esikhulu, okuzoholela ngokuqondile ekugqokeni kwe-bearing entantayo, i-thrust bear kanye nezingxenye zokuvala, ngaleyo ndlela yehlise impilo yesevisi ye-supercharger futhi ifihle izingozi ezifihliwe ukushayela okuphephile. Ngakho-ke, kuyadingeka ukwenza ukutholwa kokulinganisa okuguquguqukayo nokulungiswa kurotha ye-turbocharger.
