Menene amfanin injin turbocharger liner?
Babban aikin injin turbocharger shine ƙara yawan abin da injin ke amfani da shi, ta yadda zai ƙara ƙarfin fitarwa da ƙarfin injin, ta yadda abin hawa ya sami ƙarin ƙarfi. Musamman, turbocharger yana amfani da makamashin da ke fitar da iskar gas daga injin don fitar da kwampreso, kuma yana matsa iska a cikin bututun sha, yana kara yawan abin da ake amfani da shi, yana ba injin din damar ƙona mai da yawa, ta haka zai ƙara ƙarfin wutar lantarki.
Yadda turbocharger ke aiki
Turbocharger ya ƙunshi sassa biyu: injin turbine da kwampreso. Lokacin da injin ke aiki, ana fitar da iskar gas ta cikin bututun shaye-shaye, yana tura injin ɗin ya juya. Jujjuyawar injin turbine yana fitar da kwampreso kuma yana matsa iska a cikin bututun sha, wanda hakan zai kara matsa lamba da inganta ingantaccen konewa da fitarwar wutar lantarki.
Abũbuwan amfãni da rashin amfani na turbochargers
Abvantbuwan amfãni:
Ƙarfafa ƙarfin wutar lantarki: Turbochargers suna iya ƙara yawan shan iska, ƙyale injin ya samar da ƙarin ƙarfi da ƙarfi don ƙaura guda ɗaya.
Inganta tattalin arzikin man fetur: Injin da turbocharged ƙona mafi alhẽri, yawanci ceton 3% -5% na man fetur, da kuma da high AMINCI, mai kyau matching halaye da na wucin gadi mayar da martani .
Daidaita zuwa tsayi mai tsayi: turbocharger na iya sa injin ya kula da babban ƙarfin wutar lantarki a babban tsayi, don magance matsalar bakin ciki na iskar oxygen a tsayi mai tsayi.
Rashin hasara:
Turbine hysteresis : saboda rashin inertia na turbine da matsakaicin matsayi, lokacin da iskar gas ya karu ba zato ba tsammani, saurin turbine ba zai karu nan da nan ba, yana haifar da haɓakar wutar lantarki.
Ƙarƙashin saurin gudu ba shi da kyau: a cikin yanayin ƙananan gudu ko cunkoson ababen hawa, tasirin turbocharger ba a bayyane yake ba, har ma fiye da injin da ake so.
Ana yin caja na motoci da abubuwa daban-daban kamar ƙafafu, bearings, harsashi da abubuwan motsa jiki. Yawancin ƙafafun ana yin su ne da kayan superalloy, kamar Inconel, Waspaloy, da sauransu, don saduwa da buƙatun zafin jiki da matsa lamba.
Yawancin lokaci ana yin ƙugiya da cermet da sauran kayan don haɓaka juriya da lalata.
Don bangaren harsashi, kwampreso harsashi yawanci aluminum gami ko magnesium gami don rage nauyi da inganta yadda ya dace, yayin da harsashi turbine galibi simintin karfe ne.
The impeller da shaft aka yafi sanya daga karfe, musamman compressor impeller sau da yawa amfani da superalloy, wanda yana da kyau kwarai high zafin jiki hadawan abu da iskar shaka juriya, ƙarfi da kuma lalata juriya .
Kayayyakin sassa daban-daban da ayyukansu
Ƙaƙwalwar ƙafar ƙafa: yin amfani da kayan haɗin gwal mai zafi, irin su Inconel, Waspaloy, da dai sauransu, don saduwa da bukatun babban zafin jiki da matsa lamba.
Bearing: yawanci ana amfani da yumbu na ƙarfe da sauran kayan don inganta lalacewa da juriya na lalata.
harsashi:
Kwampreso harsashi: mafi yawa aluminum gami ko magnesium gami, don rage nauyi da kuma inganta yadda ya dace.
Turbine harsashi: yawanci simintin karfe abu.
impellers da shafts: mafi yawa karfe, musamman compressor impellers sau da yawa amfani superalloy, wannan gami yana da kyau kwarai high zafin jiki hadawan abu da iskar shaka juriya, ƙarfi da kuma lalata juriya.
Abubuwan da ke tasiri na zaɓin abu
Zaɓin kayan aikin turbocharger ya fi la'akari da waɗannan abubuwan:
Babban zafin jiki da matsa lamba: yanayin zafi na ciki da matsa lamba na turbocharger yana da girma, kuma wajibi ne a zabi kayan da ke da zafi mai kyau da tsayin daka.
Juriya na sawa: sassan da aka damu suna buƙatar samun juriya na lalacewa don inganta rayuwar sabis.
Kayan aikin injiniya: kayan suna buƙatar samun isasshen ƙarfi da ƙarfi don saduwa da buƙatun aiki mai sauri.
Idan kana son ƙarin sani, ci gaba da karanta sauran labaran kan wannan rukunin yanar gizon!
Da fatan za a kira mu idan kuna buƙatar irin waɗannan samfuran.
