Fuel Injector 107-1230 1071230 for Caterpillar 950f 950f II 960f Caterpillar 3114 Engine Caterpillar 3116 Engine

Umthelela wobubanzi be-nozzle, ingcindezi yomjovo kanye nezinga lokushisa elizungezile ezicini zesifutho enjinini kadizili(ingxenye 4)

Njengoba igrafu ikhombisa ubude bokungena kuMfanekiso 9 kanye noFigure 10 kusetshenziswa i-ambient ehlukene.

izinga lokushisa lika-0.12 mm kanye no-0.2 mm we-nozzle ububanzi likhuphuka njalo ngesikhathi esithathiwe futhi kokubili izinga lokushisa ubude bokungena akunikezi okuhluke kakhulu.Lokhu kungenxa yobubanzi obuphakathi kwamazinga okushisa abukho bukhulu kakhulu.Kodwa-ke, ingcindezi yomjovo inomthelela kubude bokungena kwesifutho, lapho ingcindezi yomjovo ehlukile engu-40 MPa, 70 MPa kanye ne-140 MPa enomfutho we-ambient ongu-1 MPa ngomfutho womoya.Njengomjovo ophakeme wokucindezela, ukungena okude ubude kuzothonya.Lokhu kungenxa yokuthi isifutho saphikiswa nengcindezi ye-ambient.

Umfanekiso 11 no-12 ubonisa amagrafu obude bokuhlukana anobubanzi obungu-0.12 mm no-0.2 mm wombhobho.Kunomphumela wokuguquguquka kwezinga lokushisa elingu-500 K, lapho ingcindezi yomjovo engu-140 MPa kanye nobubanzi benobhobho engu-0.2 mm ikhuphuka ngokuphawulekayo isuka ku-1 mm imile iye ku-2.3 mm.Lokhu mhlawumbe kungenxa yokuthi i-droplet ayizange ihlukane futhi iba yinde, lokhu kubizwa njengengxenye ye-ligament.Qhathanisa nezinga lokushisa elingu-700 K ku-140 MPa kanye nobude bokuhlukana obungu-0.2 mm bugeleza ngokungaguquki ngesikhathi.Ngakho-ke izinga lokushisa lithonya izinga lokushisa eliphakeme le-ambient elisetshenzisiwe, ubude obufushane bokuhlukana kwenzeka engxenyeni eyinhloko.

4. Isiphetho

Lolu cwaningo lubonise ukugeleza kokulingisa kukaphethiloli ogeleza kusifutho se-nozzle ngaphambi kokusha.Ukucindezela komjovo ophansi ekamelweni kuzophazamisa ukuhlukana kwesifutho sikaphethiloli sibe amaconsi amancane kakhulu ngaphambi kokuqala ukuthungela kukaphethiloli.Ukushintsha kwezinga lokushisa ekamelweni nakho kuthinta ubude bokungena kwesifutho.Emazingeni okushisa aphezulu e-ambient, isibaseli siyahwamuka kalula futhi sithungele isibaseli ngokwaso.Futhi, ububanzi bombhobho buphinde buthinte ubude bokwehlukana komlomo wesifutho njengoba kuthonywa ingcindezi ephezulu yomjovo lapho ubude bokuhlukana buba bufushane.
