.Isenzo se-nozzle yokupholisa i-piston
Vimbela ukushisisa kwepiston, isifutho sikawoyela wokugcoba
Umsebenzi oyinhloko we-piston cooling nozzle 1
Umsebenzi oyinhloko we-piston cooling nozzle ukuvimbela i-piston ekushiseni ngokweqile. Ngaphakathi kwepiston, izofafaza uwoyela wenjini, ukuze yehlise ngempumelelo izinga lokushisa lepiston, ivimbele ukushisa ngokweqile. Uma umbhobho wokupholisa i-piston unephutha, kuzoholela ekupholiseni okungekuhle kwepiston, okuzodala izinkinga njengokunwetshwa ngokweqile kwepiston, i-oyili yokugcoba i-carbonization, ukunamathela kwendawo eshelelayo kanye nokushiswa.
Umgomo wokusebenza kanye nesimo sohlelo lokusebenza lombhobho wokupholisa we-piston
Umbhobho wokupholisa we-piston usebenzisa ithuba lokupholisa uwoyela wenjini ukunciphisa izinga lokushisa lepiston ngokufaka i-atomizing futhi ufafaze uwoyela wenjini ngaphakathi kwepiston. Lo mklamo uqinisekisa ukuthi i-piston ingakwazi ukugcina ukusebenza okuvamile ngaphansi kwezinga lokushisa eliphezulu kanye nezimo zokusebenza eziphezulu zomthwalo, ngaleyo ndlela yandise impilo yesevisi yenjini. Ama-piston cooling nozzles asetshenziswa kakhulu ezinjinini zezimoto futhi ayizingxenye ezibalulekile zokuqinisekisa ukusebenza okujwayelekile kwezinjini.
Uhlolojikelele lwesimiso sokusebenza se-piston cooling nozzle
Umgomo wokusebenza wombhobho wokupholisa i-piston uphathelene kakhulu nokunikezwa nokulawulwa kukawoyela. Lapho injini isebenza, iphampu kawoyela ithumela iphampu kawoyela ku-nozzle, futhi yenza isifutho sikawoyela siye endaweni yepiston ngendlela yenkungu ngokusebenzisa umshini olawula ingcindezi ngaphakathi emlonyeni. Lesi sifutho siqinisekisa ukuthi amafutha ahlanganiswe ngokulinganayo ebusweni be-piston, okwenza ifilimu yokuzivikela ephumelelayo. Ngesikhathi esifanayo, ukusebenza kwe-fluidity nokusebenza kokudlulisa ukushisa kungathuthukisa umphumela wokudlulisa ukushisa futhi kuthuthukise ukusebenza kahle kokupholisa.
Imishini ethile yokusebenza ngaphansi kwezinhlobo ezahlukene zenjini
isimo semoto ebandayo:
Esimeni esibandayo, i-valve yebhodi lekhompyutha yenjini yokulawula i-solenoid valve inamandla, futhi i-solenoid valve ivula umzila kawoyela egumbini lokucindezela. Amafutha angena egunjini lokucindezela futhi, ngaphansi kwesenzo somfutho kawoyela kanye nomfutho wasentwasahlobo, aphushela i-plunger kwesokunxele, avimbe indlela kawoyela eya embotsheni yokupholisa ipiston. Ngalesi sikhathi, akukho ukucindezela kwamafutha esiteshini samafutha se-nozzle yokupholisa i-piston, futhi i-piston ngeke ipholiswe.
Isimo semoto eshisayo :
Esimweni semoto eshisayo, i-valve ye-solenoid ivaliwe, ivimbela umzila wamafutha ekamelweni lokucindezela. Amafutha angangena kuphela kubhobho lokupholisa le-piston, ngoba umfutho kawoyela mkhulu kunomfutho wasentwasahlobo, cindezela i-plunger kwesokudla, uvule umgudu kawoyela kumbhobho wokupholisa wepiston. Ngalesi sikhathi, umzila wamafutha we-piston cooling nozzle ugcwele amafutha, futhi i-piston ipholile.
I-Volvo diesel:
Izimbobo zokupholisa ze-piston zezinjini zikadizili zakwaVolvo zehlisa izinga lokushisa lepiston ngokufafaza uwoyela opholisayo. Iphampu kawoyela ithumela iphampu kawoyela ku-nozzle, futhi ngomshini wokulungisa ingcindezi ngaphakathi emlonyeni, amafutha afafazwa endaweni ye-piston ngendlela yenkungu, ukuze kuqinisekiswe ukuthi uwoyela umbozwe ngokulinganayo, enze ifilimu evikelayo, futhi ukuthuthukisa ukusebenza kahle kokupholisa.
