Yemhando yepamusoro Diesel Injector Nozzle DLLA155P202 yeDiesel Fuel Jekiseni Zvikamu

Disassembly uye Kuongororwa kweInjector Musoro uye Kugadzira Kugadzirisa Unyanzvi hwejekiseni nozzle Kubatanidza (chikamu 4)

Zvinodiwa zvinofananidzwa pakati pegomba rejojo ​​yemuviri wejekiseni uye nemusoro mudiki wejekiseni nozzle zvakare zvakakwirira kwazvo, uye general clearance i 0.02-0.06mm.Gomba rejojo ​​yemuviri wejekiseni idiki zvakanyanya (aya mamiriro achawanikwa kana jekiseni rasarudzwa), unogona kuunganidza muromo wejekiseni mumuviri wejekiseni, wobva wadzvanya muromo wejekiseni zvishoma kuti ugadzire musoro mudiki. jekiseni rinobuda mujekiseni remuviri rakafuratira.Wobva waburitsa muromo wejekiseni, vhara kumucheto kudiki kwemuviri wejekiseni nechikamu chekumisikidza chepakati, wopinza kamucheto kadiki kejekiseni muburi diki remuviri wejekiseni.Ita izvi kakawanda kusvikira wasununguka zvishoma.

Kana gomba rejojo ​​remuviri wejekiseni rakakura, vhara chikamu chiduku chemuviri wejekiseni nechepakati pekuisa nzvimbo, uye urove ne 120 ° conical punch (Fig. 7, Fig. 8, Fig. 9).

Kuoma kweiyo percussion kunofanirwa kutariswa zvichienderana nehukuru hwegomba, uye ipapo muromo wejekiseni unofanirwa kuiswa mukati kusvika wagona kutenderera.Kana gomba remuromo riri diki, harifanirwe kugogodzwa kubva kunze kuenda mukati, kana zvisina kudaro muromo wejekiseni unomhanya kubva kumucheto, zvichikonzera kushata kweatomization panguva yekushandiswa.Nekuda kwekusiyana kwekupfeka kwemisoro midiki yejekiseni nozzle, hapana chikonzero chekushandisa yakakosha punching chishandiso chekubaya.

Mushure mekucheka, jekiseni muromo uye jekiseni nozzle muviri unofanirwa kunyatsocheneswa usati waongororwa.
