Kodi kugwiritsa ntchito turbocharger liner ndi chiyani?
Ntchito yayikulu ya turbocharger yamagalimoto ndikuwonjezera kuchuluka kwa injini, potero kumawonjezera mphamvu yamagetsi ndi makokedwe a injini, kuti galimotoyo imapeza mphamvu zambiri. Mwachindunji, turbocharger imagwiritsa ntchito mphamvu ya gasi yotulutsa mpweya kuchokera ku injini kuyendetsa kompresa, ndikukankhira mpweya mu chitoliro cholowetsa, kukulitsa kachulukidwe, kupangitsa injini kuwotcha mafuta ochulukirapo, potero kumawonjezera mphamvu.
Momwe turbocharger imagwirira ntchito
Turbocharger imapangidwa makamaka ndi magawo awiri: turbine ndi kompresa. Pamene injini ikugwira ntchito, mpweya wotulutsa mpweya umatulutsidwa kudzera muzitsulo zotulutsa mpweya, ndikukankhira turbine kuti izungulire. Kuzungulira kwa turbine kumayendetsa kompresa ndikukanikizira mpweya mu chitoliro cholowetsa, motero kumawonjezera mphamvu yolowera ndikuwongolera kuyatsa bwino komanso kutulutsa mphamvu.
Ubwino ndi kuipa kwa turbocharger
Ubwino:
Kuchulukitsa kwamphamvu : Ma Turbocharger amatha kuchulukitsa mpweya, kulola injini kutulutsa mphamvu zambiri ndi torque pakusamuka komweko.
Kuchulukirachulukira kwamafuta amafuta : Injini zokhala ndi ma turbocharged zimawotcha bwino, nthawi zambiri zimapulumutsa 3% -5% yamafuta, ndipo zimakhala zodalirika kwambiri, zofananira bwino komanso kuyankha kwakanthawi.
sinthani kumtunda wautali: turbocharger imatha kupanga injini kukhalabe ndi mphamvu zambiri pamalo okwera, kuthana ndi vuto la okosijeni wochepa kwambiri pamalo okwera.
Kuipa :
Turbine hysteresis : chifukwa cha inertia ya turbine ndi kubereka kwapakati, pamene mpweya wotulutsa mpweya ukuwonjezeka mwadzidzidzi, liwiro la turbine silidzawonjezeka nthawi yomweyo, zomwe zimapangitsa kuti mphamvu iwonongeke.
Liwiro lotsika silili bwino: pakakhala liwiro lotsika kapena kupanikizana kwa magalimoto, zotsatira za turbocharger sizodziwikiratu, ngakhale zili bwino kuposa injini yofunidwa mwachilengedwe.
Ma turbocharger amagalimoto amapangidwa ndi zinthu zosiyanasiyana monga mawilo, mayendedwe, zipolopolo ndi ma impellers. Mawilo nthawi zambiri amapangidwa ndi zida za superalloy, monga Inconel, Waspaloy, etc., kuti akwaniritse zofunikira za kutentha kwambiri komanso kupanikizika .
Ma bearings nthawi zambiri amapangidwa ndi cermet ndi zida zina kuti apititse patsogolo kuvala komanso kukana dzimbiri.
Pagawo la chipolopolo, chipolopolo cha kompresa nthawi zambiri chimakhala aluminium alloy kapena aloyi ya magnesium kuti muchepetse kulemera komanso kuwongolera bwino, pomwe chipolopolo cha turbine nthawi zambiri chimakhala chitsulo.
Choyikapo ndi shaft chimapangidwa makamaka ndi chitsulo, makamaka chotengera cha kompresa nthawi zambiri chimagwiritsa ntchito superalloy, yomwe imakhala ndi kukana kwambiri kutentha kwa okosijeni, mphamvu komanso kukana dzimbiri.
Zida zamagulu osiyanasiyana ndi ntchito zawo
wheel hub : kugwiritsa ntchito zida za alloy zotentha kwambiri, monga Inconel, Waspaloy, ndi zina zambiri, kuti zikwaniritse zofunikira za kutentha kwambiri komanso kupanikizika.
kunyamula : Nthawi zambiri amagwiritsa ntchito zitsulo za ceramic ndi zinthu zina kuti zithandizire kuti zisawonongeke komanso kuti dzimbiri.
chipolopolo:
kompresa chipolopolo: makamaka aluminium alloy kapena magnesium alloy, kuti achepetse kulemera komanso kukonza bwino.
turbine chipolopolo: makamaka zitsulo zotayidwa.
zotulutsa ndi ma shafts : makamaka zitsulo, makamaka zopangira kompresa nthawi zambiri zimagwiritsa ntchito superalloy, alloy iyi imakhala ndi kukana kutentha kwambiri kwa okosijeni, mphamvu komanso kukana dzimbiri.
Zomwe zimakhudzidwa pakusankha zinthu
Kusankhidwa kwa zida za turbocharger makamaka kumaganizira izi:
Kutentha kwakukulu komanso kuthamanga kwambiri : kutentha kwa mkati ndi kuthamanga kwa turbocharger ndizokwera kwambiri, ndipo m'pofunika kusankha zipangizo zokhala ndi kutentha kwabwino komanso kukana kuthamanga kwambiri.
kukana kuvala: magawo omwe ali ndi nkhawa ayenera kukhala ndi kukana kovala kuti apititse patsogolo moyo wautumiki.
Makina amakina: zida zimafunika kukhala ndi mphamvu zokwanira komanso kulimba kuti zikwaniritse zofunikira zantchito yothamanga kwambiri.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. adadzipereka kugulitsa zida zamagalimoto za MG&750 zolandilidwa kugula.
