Fuel Injector Nozzle Ejbr04501d R04501d A6640170121 for Ssangyong Korando Kyron Rexton Rodius Engine E-Xdi 200

Yakagadzirwa nemhando yepamusoro yesimbi inotakura, inotsvedza cylindrical clearance inongova 0.001mm-0.0025mm, inowanikwa nepamusoro-chaiyo machining kana kugaya sarudzo, uye akasiyana mafuta injector couplings haashanduke.Kana gaka racho rakakura zvakanyanya, kudzvanywa kwejekiseni kunodonha uye mhando yekupfapfaidza ichadzikira;Iyo gap idiki kwazvo, uye vharafu yetsono iri nyore kuita jam.Iyo annular cone (kudzvanywa-inotakura koni) iri pakati pevharuvhu yetsono iri mu annular mhango yemafuta emuviri wetsono yevharuvhu, uye basa rayo nderekumira neaxial thrust inogadzirwa nekumanikidza kwemafuta kuita kuti valve yetsono isimuke.Koni iri kumucheto kwezasi kwevharuvhu yetsono (sealing cone) inofanana nemuviri wevharuvhu yetsono kuvhara mukati memukati wejekiseni.

Chikamu chepamusoro chevhavhavha yetsono ine bendekete rakakomberedzwa, kana vheji yetsono yakavharwa, chinhambwe h pakati pepfudzi uye nechepazasi pekupedzisira chiso chemuviri wejekiseni ndiko kukwidziridzwa kwevhavhavha yetsono, uye saizi yayo inotaridza huwandu hwe. jekiseni remafuta, kazhinji H=0.4mm-0.5mm.Kune 1-2 yekuwana mapini 8 panosangana vheji yetsono muviri uye jekiseni kudzivirira tsono vharafu muviri kubva kutenderera kudzivirira kusarongeka kwegomba rekupinza mafuta.

Kana jekiseni riri kushanda, iyo yakakwira-kudzvanya dhiziri kubva papombi yejekiseni, kuburikidza nepombi yemafuta yakabatana muinopinza yemafuta pane injector muviri, uyezve mune annular mhango yemafuta pakati pemuviri wetsono, ichiita pakumanikidza. -inotakura koni yevharuvhu yetsono, ichigadzira axial inokwira kumusoro pavharuvhu yetsono, kana kusvetwa uku kuri kukuru kupfuura pre-kudzvanywa kwejekiseni regulator chitubu, vheji yetsono inosimuka pakarepo, inovhura gomba rejekiseni, uye yakakwirira- dhiziri mafuta edhiziri anobva apinzwa mukamuri rinopisa.Kana pombi yejekiseni yemafuta ichimira kugovera oiri, kudzvanywa kuri muchikamu chemafuta ekudzvanya kunodonha nekukurumidza, uye vharafu yetsono inodzokera panzvimbo nenguva pasi pekuita kwekumanikidza kunodzora chitubu, uye gomba rejekiseni rinovharwa kuti rimise mafuta. jekiseni.

Huwandu hushoma hwemafuta edhiziri anopinda mugomba reoiri yeanular yemuviri wevharuvhu inoyerera ichienda kune yekumanikidza inodzora chitubu kuburikidza nemukaha uripo pakati penzvimbo yekusangana kwevaviri vanojejekita, inopinda mupombi yekudzorera mafuta, uye inoyerera ichidzokera kune sefa, iyo iri. yaishandiswa kuzora vaviri vanobaya jekiseni remafuta.

Iyo yekuvhura dzvinyiriro (injection pressure) yevharuvhu yetsono inoenderana nekutakurwa kweiyo regulator chitubu.Injini dzakasiyana dzine akasiyana majekiseni ekumanikidza zvinodiwa, izvo zvinogona kugadziridzwa neiyo pressure regulating screw, iyo pressure inowedzera kana yaiswa mukati uye inodzikira kana yadzvanywa.
