Ikhwalithi Ephakeme I-Common Rail Diesel /Fuel Injector Nozzle DLLA145P014

Ukuqaqa kanye Nokuhlolwa Kwekhanda Lomjovo kanye Namakhono Okulungisa Ukugaya Okuxhunywa Kwevalve Yenaliti (ingxenye 1)

I-fuel injector ingenye yezingxenye ezibalulekile zenjini ye-diesel, futhi ukusebenza kwayo kuthinta ngokuqondile amandla, umnotho, ukwethembeka kanye nokukhipha injini ye-diesel.

Lapho injini kadizili isebenza ngesivinini esikhulu, uphethiloli ofakwe kusilinda ophuma kumjovo kaphethiloli kufanele uthunge ngokushesha ngangokunokwenzeka, futhi ushise ngokushesha ngesikhathi esingcono kakhulu, ukuze uguqule amandla ekhemikhali kaphethiloli abe amandla omshini. oshayela injini ngezinga eliphezulu.Ukufeza lokhu, i-injector kufanele ihlangabezane nezidingo ezilandelayo:

(1) Umjovo kaphethiloli kufanele ube nomfutho othile womjovo kanye nobubanzi.

Ingcindezi yomjovo we-injector isethwe yi-spring elawula ingcindezi, futhi ububanzi abuhlobene kuphela nokucindezela komjovo kanye nokucindezela kwangemuva kwegumbi elivuthayo, kodwa futhi kuhlobene nezici zesakhiwo ezifana nobubanzi bembobo ye-nozzle kanye umumo we-valve yenaliti.

(2) Kumelwe kube nendlela efanelekile yomjovo kanye ne-engeli yekhoni yomjovo ehambisana nokuma kwegumbi elivuthayo.

(3) Kumelwe kube nokusebenza okuhle kwe-atomization, okuwukuqinisekisa ukuthi uphethiloli ojovwe ungaxutshwa ngokushesha nangokulinganayo nomoya ukuze uthole ukusha okwanele.

(4) Isikhathi sokumisa umjovo kaphethiloli sicocekile, okusho ukuthi, ukunikezwa kukaphethiloli kunganqanyulwa ngokushesha futhi ngokuphelele ekupheleni komjovo kaphethiloli, futhi akukho ukuvuza kukaphethiloli okuvunyelwe.

(5) Kufanele ikwazi ukumelana nezimo ezinzima ezifana nokushisa okuphezulu nokucindezela okukhulu, ukuze isetshenziswe ngokuphepha isikhathi eside.Ngenxa yokuthi umjovo kaphethiloli ubhekene nezinga lokushisa eliphezulu kanye negesi enomfutho ophezulu, izinga lokushisa nokucindezela kushintsha ngokuzumayo, futhi ukugeleza kukaphethiloli ngesivinini esikhulu kuyaguga, ukungcola kukaphethiloli kuyaguga kanye negesi elimazayo (i-sulfur dioxide) ekhiqizwa kuphethiloli corrodes futhi iguge.

Ngakho-ke, ukuze ugcine i-injector kaphethiloli isesimweni esihle sokusebenza, kuyadingeka ukuqinisa ukuhlolwa nokugcinwa okuvamile kwezingxenye zegumbi lokushisa injini kanye nesistimu ye-fuel.
