Isenzo se-piston cooling nozzle
Vimbela ukushisa ngokweqile kwepiston, isifutho sikawoyela sokugcoba
Umsebenzi oyinhloko we-piston cooling nozzle 1
Umsebenzi oyinhloko wombhobho wokupholisa we-piston ukuvimbela i-piston ekushiseni ngokweqile. Ngaphakathi kwe-piston, izofafaza uwoyela wenjini, ukuze yehlise izinga lokushisa le-piston ngempumelelo, ivimbele ukushisa ngokweqile. Uma umbhobho wokupholisa we-piston unephutha, kuzoholela ekupholiseni kabi kwe-piston, okuzobangela izinkinga ezifana nokwanda ngokweqile kwe-piston, ukugcoba uwoyela nge-carbonization, ukunamathela ebusweni obushelelayo kanye nokusha.
Isimiso sokusebenza kanye nesimo sokusebenza kwe-piston cooling nozzle
I-nozzle yokupholisa ye-piston isebenzisa umphumela wokupholisa kawoyela wenjini ukunciphisa izinga lokushisa le-piston ngokufaka i-atomize bese ifafaza uwoyela wenjini ngaphakathi kwe-piston. Lo mklamo uqinisekisa ukuthi i-piston ingagcina ukusebenza okuvamile ngaphansi kwezimo zokusebenza ezishisa kakhulu nezinomthwalo ophezulu, ngaleyo ndlela yandisa impilo yenjini. Ama-nozzle okupholisa e-piston asetshenziswa kabanzi ezinjinini zezimoto futhi ayizingxenye ezibalulekile ukuqinisekisa ukusebenza okuvamile kwezinjini.
Isifinyezo sesimiso sokusebenza se-nozzle yokupholisa ye-piston
Umgomo wokusebenza kwe-piston cooling nozzle ugxile kakhulu ekuhlinzekweni nasekulawulweni kwamafutha. Lapho injini isebenza, i-oil pump ithumela i-oil pump ku-nozzle, futhi yenza i-oil spray ebusweni be-piston ngesimo senkungu ngokusebenzisa indlela yokulawula ingcindezi ngaphakathi kwe-nozzle. Lesi spray siqinisekisa ukuthi amafutha ambozwe ngokulinganayo ebusweni be-piston, okwenza ifilimu evikelayo esebenzayo. Ngesikhathi esifanayo, ukugeleza kanye nokusebenza kokudlulisa ukushisa kwamafutha kungathuthukisa umphumela wokudlulisa ukushisa futhi kuthuthukise ukusebenza kahle kokupholisa.
Indlela yokusebenza ethile ngaphansi kwezinhlobo ezahlukene zenjini
isimo semoto ebandayo:
Uma kubanda, i-valve ye-solenoid yokulawula ibhodi lekhompyutha yenjini iyanikwa amandla, bese i-valve ye-solenoid ivula indlela yamafutha eya ekamelweni lokucindezela. Uwoyela ungena ekamelweni lokucindezela futhi, ngaphansi kwesenzo sokucindezela uwoyela kanye nokucindezela kwentwasahlobo, usunduza i-plunger ngakwesobunxele, uvimba indlela yamafutha eya embozweni yokupholisa i-piston. Ngalesi sikhathi, akukho ngcindezi yamafutha emzileni wamafutha we-nozzle yokupholisa i-piston, futhi i-piston ngeke ipholiswe.
Isimo semoto eshisayo:
Esimweni semoto esishisayo, i-solenoid valve ivaliwe, ivimba indlela kawoyela eya ekamelweni lokucindezela. Uwoyela ungangena kuphela embotsheni yokupholisa ye-piston, ngoba umfutho kawoyela mkhulu kunomfutho wentwasahlobo, cindezela i-plunger ngakwesokudla, uvule isiteshi samafutha embotsheni yokupholisa ye-piston. Ngalesi sikhathi, isiteshi samafutha sembotsheni yokupholisa ye-piston sigcwele uwoyela, bese i-piston ipholiswa.
I-Volvo diesel:
Ama-nozzle okupholisa e-piston ezinjini ze-Volvo diesel anciphisa izinga lokushisa kwe-piston ngokufutha uwoyela opholile. I-oil pump ithumela i-oil pump e-nozzle, futhi ngendlela yokulungisa ingcindezi ngaphakathi kwe-nozzle, uwoyela ufafazwa ebusweni be-piston ngesimo senkungu, ukuqinisekisa ukuthi uwoyela umbozwe ngokulinganayo, kwakha ifilimu evikelayo, futhi kuthuthukiswe ukusebenza kahle kokupholisa.
