Iyini i-gasket ye-exhaust manifold
Ama-gasket e-exhaust manifold ayizingxenye ezibalulekile ohlelweni lokukhipha umoya lwezimoto, ikakhulukazi enza imisebenzi yokuvala nokuvala ukushisa. Ngokuvamile akhiwa izingqimba eziningi zamapuleti ensimbi nezinto zokuvala umoya, ezifakwe phakathi kwe-exhaust manifold kanye nekhanda lesilinda ukuvimbela igesi yokukhipha umoya eshisa kakhulu ukuthi idluliselwe ngqo kwezinye izingxenye eziku-engine compartment, ngaleyo ndlela idlala indima yokuvikela.
Izici zesakhiwo
I-gasket ye-exhaust manifold isebenzisa isakhiwo esinezingqimba ezintathu: ungqimba olungaphezulu luyipuleti lensimbi elivalayo, ungqimba oluphakathi luyinto evalayo, kanti ungqimba olungezansi luyipuleti lensimbi elivalayo, okuqinisekisa ukuthi akukho sikhala phakathi kwesembozo esivalayo kanye nekhanda lesilinda, okunciphisa ngempumelelo izinga lokushisa lamanzi ohlangothini lokukhipha umoya lwejakethi lamanzi lesilinda futhi kunciphisa umthelela wokwehluka kwezinga lokushisa enjinini.
Ukubonakaliswa kwephutha
Uma i-gasket ye-exhaust manifold yonakele, izimpawu eziyinhloko yilezi:
Umsindo engxenyeni yenjini ukhuphukile
Ukuvuza ohlelweni lokukhipha umoya kuholela ekunciphiseni kwamandla
Kungase kube nephunga lokusha okungaphelele
Ukwehluleka kokufakwa kokushisa kungabangela ukushisa ngokweqile kwezingxenye ezizungezile
Imisebenzi eyinhloko yama-gasket e-exhaust manifold ihlanganisa:
Ivaliwe futhi ayivuzi
I-gasket itholakala phakathi kwe-exhaust manifold kanye nekhanda lesilinda, okwenza kube nokuvalwa okuqinile ngesakhiwo sepuleti lensimbi ukuvimbela ukuvuza kwe-exhaust nokuqinisekisa ukukhishwa kwenjini okuvamile.
Ukuvikelwa kokushisa
Izinto zokuvikela ezingezona ezensimbi (njengesakhiwo esinezingqimba ezintathu) ziyasetshenziswa ukuvimbela ngempumelelo ukuqhutshwa kokushisa komoya ophumayo oshisa kakhulu ezingxenyeni ezifana nekhanda lesilinda namapayipi amanzi, ukunciphisa umehluko wokushisa kwejakethi lamanzi lekhanda lesilinda, nokwandisa impilo yenkonzo yenjini.
Isakhiwo esisekelayo
Inokuqina okuphezulu, okungavimbela ukugoba kokuguquguquka, kugcine isembozo sokushisa sinamathele ngokuqinile ekhanda lesilinda, futhi kuthuthukise umphumela wokuvala.
Izimpawu eziyinhloko zokwehluleka kwe-exhaust manifold gasket umsindo okhuphukile, ukwehla kwamandla kanye nokuvuza komoya, njll. Izimpawu ezithile yilezi ezilandelayo:
Umsindo uyanda
Umonakalo we-gasket uzoholela ekwehleni kokusebenza kokuvala kwesistimu yokukhipha umoya, okubangela imisindo engavamile "yokuhogela" noma "yokukhukhumeza" lapho ukugeleza komoya kudlula esibonakalayo, ikakhulukazi okusobala kakhulu ngesikhathi sokusheshisa noma ukusheshisa okungazelelwe.
Ukwehla kwamandla kanye nokwenyuka kokusetshenziswa kukaphethiloli
Ukuvuza komoya kungaholela ekungalinganini kwesilinganiso sengxube (ingxube ayiqinile kakhulu), kanti i-ECU ayikwazi ukulawula ngokunembile isilinganiso somoya-uphethiloli, okubangela ukungahlaliseki okungazinzile, ukusheshisa okubuthakathaka kanye nezinye izimo, futhi ngesikhathi esifanayo, ukusetshenziswa kukaphethiloli nakho kuzokhula ngokufanele.
Ukuvuza komoya okungavamile kanye nokukhipha umoya
Umonakalo we-exhaust manifold gasket ungabangela ukuvuza komoya, okuholela ekunciphiseni kwengcindezi yokukhipha emuva futhi kuthinte amandla okukhipha injini. Ezimweni ezimbi kakhulu, umbala ongavamile wokukhipha (njengomusi omnyama) noma ukukhishwa okukhulu komoya kungenzeka.
Ukwehla kokusebenza kokuvikela ukushisa
Uma i-gasket inesakhiwo sokuvikela ukushisa, umonakalo wayo uzokwenza ukuthi ukushisa kokukhipha umoya kudluliselwe ekhanda lesilinda senjini, okwandisa umehluko wokushisa kwamanzi futhi mhlawumbe kuthinte isikhathi sokuphila kwenjini.
Kunconywa ukuthi uhlole ngokushesha isimo se-interface yepayipi lokukhipha umoya kanye ne-gasket uma uthola izimpawu ezingenhla. Uma kudingeka, shintsha izingxenye ezonakele ukuqinisekisa ukuvalwa nokusebenza kahle kwenjini.
Umgomo wokusebenza wama-gasket amaningi e-exhaust ufeza imisebenzi yawo ngezici ezintathu ezilandelayo:
Ivaliwe futhi ayivuzi
I-gasket ye-exhaust manifold ifakiwe phakathi kwe-exhaust manifold kanye ne-flange ye-exhaust port ye-cylinder head. Isebenzisa umklamo wokuvala onwebekayo, igcwalisa iphutha lokucubungula engxenyeni yokuxhuma ngokuguqulwa kwezinto ukuze kuvinjelwe ukuvuza kwegesi ye-exhaust enokushisa okuphezulu. Uma i-gasket yehluleka, izobangela ukuvuza komoya, okungaholela ekulimaleni kwezingxenye ezizungezile noma ekugugulekeni kokushisa okuphezulu.
Ukuvikelwa kokushisa
I-gasket ifakwe isakhiwo sesembozo sokushisa sangaphakathi (i-interlayer ye-non-metallic material), esihlukanisa ngempumelelo ukushisa okuqondile kokushisa okuphezulu kokukhipha umoya ekhanda lesilinda, sinciphise izinga lokushisa lamanzi ohlangothini lokukhipha umoya lwejakethi lamanzi lekhanda lesilinda, futhi sinciphise umehluko wokushisa phakathi kohlangothi lokungenisa kanye nohlangothi lokukhipha umoya, ngaleyo ndlela sandise impilo yenkonzo yenjini.
Ukusekelwa kwesakhiwo
I-gasket isebenzisa isakhiwo esihlanganisiwe sepuleti lensimbi esinezingqimba ezintathu (ungqimba olungaphezulu lokuvala, izingqimba ezimbili zokuvikela, kanye nengqimba yokusekela engezansi), okuqinisekisa ukuthi isembozo sokuvikela sinamathele eduze kwekhanda lesilinda ngemva kokufakwa futhi kugwenywe ukwakheka kwezikhala ezibangelwa ukudlidliza.
