Yintoni enokunceda i-liner ye-turbocharger yemoto?
Indima ephambili ye-turbocharger yeemoto kukunyusa intake yenjini, ngaloo ndlela kwandisa amandla okukhupha kunye ne-torque yenjini, ukuze isithuthi sifumane amandla angakumbi. Ngokukodwa, i-turbocharger isebenzisa amandla egesi yokukhupha umoya evela kwinjini ukuqhuba i-compressor, kwaye icinezela umoya ungene kumbhobho wokungenisa, inyusa uxinano lwe-intake, ivumela injini ukuba itshise amafutha angakumbi, ngaloo ndlela inyusa i-output yamandla.
Indlela esebenza ngayo i-turbocharger
I-Turbocharger yenziwe ngamacandelo amabini: i-turbine kunye ne-compressor. Xa injini isebenza, igesi yokukhupha umoya ikhutshwa ngepayipi yokukhupha umoya, ityhala i-turbine ukuba ijikeleze. Ukujikeleza kwe-turbine kuqhuba i-compressor kwaye kucinezele umoya ungene kwipayipi yokungenisa umoya, ngaloo ndlela kunyusa uxinzelelo lokungenisa umoya kwaye kuphucule ukusebenza kakuhle komlilo kunye nokukhupha amandla.
Iingenelo kunye nokungalungi kwee-turbochargers
Iingenelo:
Ukwanda kwamandla okukhupha umoya: IiTurbochargers ziyakwazi ukwandisa ukungena komoya, zivumela injini ukuba ivelise amandla kunye ne-torque engaphezulu ukuze ikwazi ukuhamba ngendlela efanayo.
Ukuphucula ukonga amafutha: Iinjini ezine-turbocharged zitsha ngcono, zihlala zigcina i-3%-5% yamafutha, kwaye zinokuthembeka okuphezulu, iimpawu ezifanelekileyo zokufanisa kunye nokuphendula okwethutyana.
ukuziqhelanisa nokuphakama okuphezulu: i-turbocharger ingenza injini igcine amandla aphezulu xa iphezulu, ukusombulula ingxaki yeoksijini encinci xa iphezulu.
Izinto ezingalunganga:
I-Turbine hysteresis : ngenxa yokungasebenzi kakuhle kwe-turbine kunye ne-intermediate bearing, xa igesi yokukhupha umoya isanda ngequbuliso, isantya se-turbine asiyi kunyuka ngoko nangoko, nto leyo ebangela i-power output hysteresis .
Isiphumo sesantya esiphantsi asilungile: kwimeko yesantya esiphantsi okanye ukuxinana kwezithuthi, isiphumo se-turbocharger asibonakali, singcono nangakumbi kunenjini ephefumlelwayo ngokwendalo.
Ii-turbochargers zeemoto zenziwe ngezinto ezahlukeneyo ezifana namavili, iibheringi, iigobolondo kunye nee-impellers. Amavili adla ngokwenziwa ngezinto ze-superalloy, ezifana ne-Inconel, i-Waspaloy, njl.njl., ukuhlangabezana neemfuno zobushushu obuphezulu kunye noxinzelelo.
Iibheringi zihlala zenziwe nge-cermet kunye nezinye izinto ukuphucula ukuguguleka kunye nokumelana nokugqwala.
Kwinxalenye yeqokobhe, iqokobhe lecompressor ikakhulu liyi-aluminium alloy okanye i-magnesium alloy ukunciphisa ubunzima kunye nokuphucula ukusebenza kakuhle, ngelixa iqokobhe le-turbine ikakhulu liyintsimbi etyhidiweyo.
I-impeller kunye ne-shaft zenziwe ngentsimbi, ingakumbi i-compressor impeller idla ngokusebenzisa i-superalloy, enokumelana okuhle kakhulu ne-oxidation kumaqondo obushushu aphezulu, amandla kunye nokumelana nokugqwala.
Izixhobo zamacandelo ahlukeneyo kunye nemisebenzi yazo
Ihabhu yevili: ukusetyenziswa kwezinto ze-alloy ezinobushushu obuphezulu, ezifana ne-Inconel, i-Waspaloy, njl.njl., ukuhlangabezana neemfuno zobushushu obuphezulu kunye noxinzelelo.
ibhereyitha: idla ngokusetyenziswa i-ceramic yesinyithi kunye nezinye izinto ukuphucula ukuguguleka kunye nokumelana nokugqwala.
iqokobhe:
Igobolondo le-compressor: ikakhulu i-aluminium alloy okanye i-magnesium alloy, ukunciphisa ubunzima kunye nokuphucula ukusebenza kakuhle.
Iqokobhe le-turbine: ikakhulu izinto zentsimbi ezixotyulweyo.
ii-impellers kunye nee-shafts: uninzi lwazo ziintsimbi, ingakumbi ii-compressor impellers zihlala zisebenzisa i-superalloy, le alloy inokumelana okuhle kakhulu ne-oxidation kumaqondo obushushu aphezulu, amandla kunye nokumelana nokugqwala.
Izinto ezichaphazela ukukhethwa kwezinto
Ukukhethwa kwezinto ze-turbocharger ikakhulu kuqwalasela ezi zinto zilandelayo:
Ubushushu obuphezulu kunye noxinzelelo oluphezulu : ubushushu bangaphakathi kunye noxinzelelo lwe-turbocharger buphezulu, kwaye kuyimfuneko ukukhetha izixhobo ezinobushushu obuphezulu obuhle kunye noxinzelelo oluphezulu .
Ukumelana nokuguguleka: iindawo ezixinezelekileyo kufuneka zibe nokumelana nokuguguleka okuthile ukuphucula ubomi benkonzo.
Iimpawu zoomatshini: izixhobo kufuneka zibe namandla aneleyo kunye nokuqina ukuze zihlangabezane neemfuno zokusebenza ngesantya esiphezulu.
