DLLA154S082 Nyowani 100% Yakaedzwa Yakajairwa Rail Diesel / Fuel Injector BOSCH Injector Nozzle yeDongfeng

Iyo yekubvisa nzira yeinjector nozzle (Chikamu 4)

Iko kurongeka kweiyo huru yekupedzisira yakabatana pamusoro pemuviri wejekiseni yakakwirira kwazvo. Kana paine kukuvadzwa, kusaenzana, kana kuronda, ukobvu hweabrasive paste inoshandiswa inogona kutariswa zvichienderana nehuwandu hwekukuvadza.

Kukuya nzira: shandisa chimedu chegirazi rechando kana girazi rakatsetseka, riise pasi, shandisa abrasive paste, uye uibate nemaoko ako: tsikirira uye dzvanya kumucheto kuduku kweinjector muviri pamwe nesimba. Gaya kuita denderedzwa kana "8" chimiro nehupamhi hwe 60mm, uye kudzivirira girazi kuti risave risina kuenzana nekuda kwekukuya kwenguva refu. Mugumo mukuru wemuviri wakapfekwa zvisingaite.

Iro buri remuviri wejekiseni uye musoro mudiki wevharuvhu yetsono zvakare zvine zvakakwirira zvinodikanwa zvekushandira pamwe, uye general clearance ndeye 0.02-0.06mm. Kana buri remuviri wejekiseni riri diki zvakanyanya (aya mamiriro achawanikwa kana vharafu yetsono yasarudzwa), unogona kuunganidza vharafu yetsono mumuviri wejekiseni, wobva wadzvanya vharafu yetsono zvishoma kuti ugadzire musoro mudiki wejekiseni. vharafu yetsono inobuda kunze kwemuromo. Nozzle body ndege. Wobva waburitsa vharafu yetsono, vhara kumucheto kudiki kwemuviri wejekiseni nepakati pekuisa chidimbu, uye isa kamucheto kadiki kwevharuvhu yetsono mugomba diki remuviri wejekiseni. Ita izvi kakawanda kusvikira wasununguka zvishoma.

Kana buri remuviri wejekiseni rakakura, shandisa chidimbu chekumisikidza chepakati kuvhara chikamu chidiki chemuviri wejekiseni, woibaya ne120.° conical punch. Kuoma kweiyo percussion kunofanirwa kutariswa maererano nehukuru hwegomba, uye ipapo valve yetsono inofanira kuiswa mukati kusvikira yagona kutenderera.

Kana gomba remuromo riri diki, harifanirwe kugogodzwa kubva kunze kuenda mukati, zvikasadaro vharafu yetsono inomhanya kubva kumucheto, zvichikonzera kupora kwakashata panguva yekushandiswa. Pamusana pemamiriro akasiyana-siyana ekupfeka kwemisoro miduku yevhavhavha yetsono, hapana chikonzero chekushandisa punching yakakosha yekurova. Mushure mekunge vheji yetsono yagadziriswa, vheji yetsono uye muviri wejekiseni unofanirwa kunyatsocheneswa musati bvunzo dzisati dzaitwa.o refu, pulverization ichaitika nyore.
