DLLA152PN269 Yakajairika Rail Diesel / Fuel Injector BOSCH Injector Nozzle

Kuongorora uye Kutsiviwa kweInjector nozzle

Kubatanidzwa kwevharuvhu yetsono kunodaidzwawo kuti jekiseni nozzle coupling. Inoumbwa nevharuvhu yetsono uye muviri wetsono yevharuvhu kuti iite yakakwira-chaiyo coupling. Mushure mekugayiwa paviri, hazvichinjike. Mhosva huru yekusangana kwevharuvhu yetsono ndeyekuti gomba remuromo rakavharwa uye chisimbiso hachina kusimba.

1 Technical appraisal method

(1) Nzira yekucherechedza kunze. Iyo tekinoroji mamiriro eiyo mafuta injector musangano inogona zvakare kutongwa kubva kumhando yemafuta atomization. Mushure mekugadzirisa kudzvanywa kwejekiseni, kana paine makwapa emhute kana mitsara yemafuta ine ukobvu husina kuenzana mupfapfaidzo, inowanzova jekiseni remafuta. Iyo coupler yakapfeka zvakanyanya; apo mhute yemafuta inogoverwa zvisina kuenzana kana mutsara wepakati wemutsara wemafuta wakatsvedza, zvinoratidza kuti gomba remuromo harina kuchena; kana paine mafuta anodonha mushure mekupfapfaidza, zvinoreva kuti chisimbiso chevhavha yetsono haina kuvharwa zvakasimba.

(2) Kuisa chisimbiso bvunzo. Rongedza kudzvanywa kwejekiseni remafuta ejekiseni remafuta kuti ive 3-5MPa yakakwira kupfuura yakajairwa kudzvanywa, uye tarisa nguva yakapfuura apo mafuta anodonha kubva 20Pa kusvika 18Pa, izvo zvisingafanirwe kunge zvisingasviki 9-12s.

2 Chengetedzo yekutsiva

Kutsiviwa kwegungano rejekiseni kunofanira kuitwa nenzira inotevera uye nzira: (1) Bvisa chivharo chejekiseni uye lock nut, uye sunungura screwing screw. (2) Bvisa chitubu, chigaro chechitubu uye ejector pini mukutevedzana. (3) Tsungirira imba yejekiseni yemafuta pavhisi, sunungura chivharo chakasimba chejekiseni remafuta, uye bvisa jekiseni remafuta. (4) Chenesa zvidimbu zvakapatsanurwa mumafuta edhiziri akachena, uye tarisa kuti zvikamu zvacho hazvina kusimba here kana kuti kwete. Zvinotarisirwa kuti tsvimbo ye ejector isati yakakotama, bhora resimbi ye ejector rod harina kutenderera kana kusvunurwa, uye nzvimbo dzekusangana dzehoko dzakapfava uye dzisina mavara emarara. (5) Geza iyo itsva jekiseni jekiseni remafuta mumafuta edhiziri kuti ubvise mafuta anodzivirira ngura uye uite kuti nzira yemafuta, nozzle nekamuri yemafuta isavharwe. (6) Matanho egungano akapesana neaya edissembly. Paunenge uchiisa gungano rejekiseni, hazvibvumirwi zvachose kuita pasi pekumanikidzwa kwechirimo. (7) Simbisa chivharo zvinoenderana netorque yataurwa, wobva waisa tsvimbo yejector, chigaro chemuchirimo, uye kudzvanya kunoronga chitubu mugoko pamwe chete, wobva waisa screw pane inogadzirisa screw. Gadzirisa kudzvanywa kwemuyedzo we nozzle, wozokiya chivharo chakasimba mushure mekupasa bvunzo.
