Kodi kugwiritsa ntchito liner ya turbocharger yagalimoto ndi kotani?
Ntchito yaikulu ya turbocharger yamagalimoto ndikuwonjezera mphamvu ya injini, motero kuwonjezera mphamvu yotulutsa ndi mphamvu ya injini, kuti galimotoyo ipeze mphamvu zambiri . Makamaka, turbocharger imagwiritsa ntchito mphamvu ya mpweya wochokera ku injini kuyendetsa compressor, ndikukanikiza mpweya mu chitoliro cholowetsa, ndikuwonjezera kuchuluka kwa mphamvu yolowera, zomwe zimathandiza injini kuyatsa mafuta ambiri, motero kuwonjezera mphamvu yotulutsa .
Momwe turbocharger imagwirira ntchito
Turbocharger imapangidwa makamaka ndi magawo awiri: turbine ndi compressor. Injini ikakhala ikugwira ntchito, mpweya wotulutsa utsi umatuluka kudzera mu chitoliro chotulutsa utsi, ndikukankhira turbine kuti izungulire. Kuzungulira kwa turbine kumayendetsa compressor ndikukanikiza mpweya kulowa mu chitoliro cholowetsa mpweya, motero kumawonjezera kuthamanga kwa mpweya ndikuwonjezera mphamvu yoyaka komanso kutulutsa mphamvu.
Ubwino ndi kuipa kwa ma turbocharger
Ubwino:
Kuchuluka kwa mphamvu yotulutsa : Ma turbocharger amatha kuwonjezera kuchuluka kwa mpweya womwe umabwera, zomwe zimathandiza injini kupanga mphamvu zambiri komanso mphamvu yochulukirapo kuti isunthike mofanana.
Kusunga bwino mafuta: Injini zokhala ndi turbocharged zimayaka bwino, nthawi zambiri zimasunga 3%-5% ya mafuta, ndipo zimakhala zodalirika kwambiri, zimagwirizana bwino komanso zimayankha mwachangu.
zolowera kutalika kwambiri: turbocharger ingapangitse injini kusunga mphamvu zambiri pamalo okwera, kuti ithetse vuto la mpweya wochepa pamalo okwera kwambiri.
Zoyipa:
Kuthamanga kwa turbine : chifukwa cha kufooka kwa turbine ndi pakati, pamene mpweya wotulutsa utsi ukuwonjezeka mwadzidzidzi, liwiro la turbine silidzawonjezeka nthawi yomweyo, zomwe zimapangitsa kuti mphamvu yotulutsa mphamvu ituluke .
Zotsatira za liwiro lotsika si zabwino: pankhani ya liwiro lotsika kapena kudzaza magalimoto, zotsatira za turbocharger sizowonekera, ngakhale bwino kuposa injini yopangidwa mwachilengedwe.
Ma turbocharger a magalimoto amapangidwa ndi zinthu zosiyanasiyana monga mawilo, mabearing, zipolopolo ndi ma impellers. Mawilo nthawi zambiri amapangidwa ndi zinthu zopangira superalloy, monga Inconel, Waspaloy, ndi zina zotero, kuti akwaniritse zofunikira pa kutentha kwambiri ndi kupanikizika.
Mabearings nthawi zambiri amapangidwa ndi cermet ndi zipangizo zina kuti awonjezere kukana kuwonongeka ndi dzimbiri.
Pa gawo la chipolopolo, chipolopolo cha compressor chimakhala ndi aluminiyamu kapena magnesium alloy kuti chichepetse kulemera ndikuwonjezera magwiridwe antchito, pomwe chipolopolo cha turbine chimakhala ndi chitsulo chopangidwa ndi .
Impeller ndi shaft zimapangidwa makamaka ndi chitsulo, makamaka compressor impeller nthawi zambiri imagwiritsa ntchito superalloy, yomwe imakhala ndi kukana kwabwino kwambiri kwa okosijeni kutentha kwambiri, mphamvu komanso kukana dzimbiri.
Zipangizo za ziwalo zosiyanasiyana ndi ntchito zawo
Chigawo cha mawilo: kugwiritsa ntchito zipangizo zoyeretsera kutentha kwambiri, monga Inconel, Waspaloy, ndi zina zotero, kuti zikwaniritse zofunikira za kutentha kwambiri ndi kupanikizika.
Chogwirira: nthawi zambiri amagwiritsa ntchito chitsulo cha ceramic ndi zinthu zina kuti awonjezere kukana kuwonongeka ndi dzimbiri.
chipolopolo:
Chipolopolo cha compressor: makamaka aluminiyamu kapena magnesium alloy, kuti muchepetse kulemera ndikuwonjezera magwiridwe antchito.
Chipolopolo cha turbine : makamaka zinthu zopangidwa ndi chitsulo chopangidwa ndi .
Ma impeller ndi ma shafts: makamaka zitsulo, makamaka ma compressor impeller nthawi zambiri amagwiritsa ntchito superalloy, alloy iyi ili ndi kukana kwabwino kwambiri kwa okosijeni kutentha kwambiri, mphamvu komanso kukana dzimbiri.
Zinthu zomwe zimakhudza kusankha zinthu
Kusankha zipangizo za turbocharger kumaganizira makamaka zinthu zotsatirazi:
Kutentha kwambiri ndi kupanikizika kwakukulu : kutentha kwamkati ndi kupanikizika kwa turbocharger kuli kokwera, ndipo ndikofunikira kusankha zipangizo zomwe zili ndi kutentha kwakukulu komanso kukana kupanikizika kwakukulu .
Kukana kuvala: ziwalo zopsinjika ziyenera kukhala ndi kukana kuvala kuti ziwongolere moyo wautumiki.
Kapangidwe ka makina: zipangizo ziyenera kukhala ndi mphamvu zokwanira komanso zolimba kuti zikwaniritse zosowa za ntchito yothamanga kwambiri.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&750 zolandiridwa kugula.
