Lintlha tsa boithuto tsa turbocharger

Sistimi e tsamaisang rotor e ne e sebetsoa ha e ntse e le maemong a fapaneng. Teko e latelang e ile ea phethoa ho bonts'a bokhoni ba li-bearings tse nyane tsa thrust foil. Ho na le kamano e ntle pakeng tsa tekanyo le tlhahlobo. Linako tse khutšoane haholo tsa ho potlakisa rotor ho tloha phomolong ho ea ho lebelo le phahameng le tsona li ne li lekantsoe. Sebapali sa liteko tse tšoanang se sebelisitsoe ho bokella lipotoloho tse fetang 1000 tsa ho qala ho bonts'a bophelo ba ho beha le ho roala. Ho ipapisitsoe le tlhahlobo ena e atlehileng, ho lebelletsoe hore sepheo sa ho nts'etsapele li-turbocharger tse se nang oli le lienjineri tse nyane tsa turbojet tse sebetsang ka lebelo le phahameng le bophelo bo bolelele li tla finyelloa.

Litlhoko tsa ts'ebetso e phahameng, li-bearings tsa nako e telele bakeng sa sehlopha sena se secha sa mechine li matla. Li-bearings tse tloaelehileng tsa ho roala li qholotsoa haholo ke lebelo le boima ba mojaro bo hlokahalang. Ho phaella moo, ntle le haeba mokelikeli oa ts'ebetso o ka sebelisoa e le setlolo, tsamaiso ea ka ntle ea lubrication e tla batla e le joalo.

Ho felisa li-bearings tse tlotsitsoeng ka oli le tsamaiso ea phepelo e amanang le eona ho tla nolofatsa sistimi ea rotor, ho fokotsa boima ba sistimi, le ho ntlafatsa ts'ebetso, empa ho tla eketsa mocheso o ka hare, o tla hloka li-bearings tse khonang ho sebetsa ka mocheso o fihlang ho 650 ° C le ka lebelo le phahameng. meroalo. Ntle le ho pholoha lithempereichara le lebelo le feteletseng, li-bearings tse se nang oli le tsona li tla hloka ho amohela maemo a ts'oenyeho le ho thothomela a fumanehang lits'ebetsong tsa mehala.

Bokhoni ba ho sebelisa li-bearings tse lumellanang le lienjineri tse nyane tsa turbojet bo bonts'itsoe tlas'a maemo a fapaneng a mocheso, ho ts'oha, mojaro le lebelo. Liteko tse fihlang ho 150,000 rpm, ka mocheso o nang le mocheso o ka holimo ho 260 ° C, tlas'a khatello ea maikutlo ho 90g le li-rotor orientations tse kenyeletsang 90 deg pitch le roll, kaofela li ile tsa phethoa ka katleho. Tlas'a maemo ohle a lekiloeng, rotor e nang le foil e tšehetsoeng e ile ea lula e tsitsitse, ho sisinyeha ho ne ho le tlaase, 'me mocheso oa ho jara o tsitsitse. Ka kakaretso, lenaneo lena le fane ka semelo se hlokahalang ho theha turbojet e se nang oli ka botlalo kapa enjene ea turbofan e sebetsang hantle haholo.
