Umsebenzi we-turbocharger impeller

Umsebenzi weturbocharger impeller kukusebenzisa amandla erhasi yokukhupha ukucinezela umoya othathayo, ukwandisa umthamo wokuthatha, nokuthumela irhasi exubeneyo ephezulu kwigumbi lokutsha ukuze kutsha kunyuswe amandla emveliso ye-injini kunye nokwandisa i-torque ye-injini, ngaloo ndlela inyusa i-injini. amandla.

Kutheni le nto i-impeller ye-turbocharger kufuneka ilungelelaniswe ngokuguquguqukayo?Ii-turbocharger ngokwenene umoyaicompressor oko kwandisa umthamo wokungenisa ngokucinezela umoya.Isebenzisa impembelelo inertial yerhasi yokukhupha ekhutshwa yi-injini ukuqhubaiturbine kwigumbi le turbine.I-injini yomoya iqhuba i-coaxial impeller, kwaye i-impeller icinezela umoya othunyelwe ngumbhobho wokucoca umoya ukuwucinezela kwi-cylinder.Xa isantya se-injini sinyuka, isantya sokukhutshwa kwegesi ephumayo kunye nesantya se-injini yomoya sinyuka ngokuhambelanayo, kwaye i-impeller icinezela ngakumbi umoya kwi-cylinder.Ukunyuka koxinzelelo lomoya kunye nokuxinana kunokutshisa amafutha amaninzi.Ukunyuka okuhambelana nomthamo wamafutha kunye nokulungelelaniswa kwesantya se-injini kunokunyusa amandla emveliso ye-injini.

Iinjini i-exhaust turbocharger ngoku isetyenziswa ngokubanzi.I-turbocharger i-rotor shaft isetyenziswa kwindawo esebenza ngesantya esiphezulu, ngesantya esingama-10,000 ukuya ngaphezulu kwama-200,000 erevolutions ngomzuzu.Phantsi kolu jikelezo lwesantya esiphezulu, ulungelelwaniso oluguquguqukayo kufuneka lwenziwe.Ngomatshini wokulinganisa oguqukayo we-turbocharger, ubhaqo olusebenzayo lokulinganisa oluguquguqukayo lunokufezekiswa.

I-turbochargeri-impeller rotor shaft kunye nomzimba ubhekiselele kwi-forging enamandla aneleyo omatshini wokumelana ne-torque ehanjiswa yi-prime mover kunye ne-torque enkulu ye-electromagnetic yesekethe emfutshane ngequbuliso kwindawo yokukhupha ijenereyitha, kwaye ube ne-conductivity entle yemagnethi, engumthwali wepali yemagnethi ephambili. ijenereyitha.

Ngophuhliso oluqhubekayo lwe-automotive turbocharging technology, isantya sokusebenza sangoku sendibano ye-rotor ye-turbocharger sinokufikelela kwi-60000r / min ukuya kwi-240000r / min.Njengondoqoicandeloye-supercharger, i-rotor ye-supercharger iya kubangela ukungcangcazela okukhulu kunye nengxolo ngexesha lokujikeleza kwesantya esiphezulu, okuya kukhokelela ngokuthe ngqo ekunxityweni kweebheringi ezidadayo, ukuthwala i-thrust kunye nokutywinwa kwamalungu, oko kunciphisa ubomi benkonzo ye-supercharger kunye nokufihla iingozi ezifihliweyo. ukuqhuba ngokukhuselekileyo.Ngoko ke, kuyimfuneko ukwenza ukufumanisa ukulinganisa okuguquguqukayo kunye nokulungiswa kwi-rotor ye-turbocharger.
