High Quality New Diesel Injector Nozzle DLLA144P2273 0433172273 0 433 172 273 Common Rail Injector Nozzle yeBosch Spare Parts

Fuel injector yekuongorora maitiro

Kuongororwa kwemusangano wevharuvhu yetsono kunosanganisira: kutarisa kwepamusoro kwekuona, kutsvedza kuongorora, kuvhara chisimbiso uye kuongorora kupfapfaidza, nezvimwe.

3.1 Iyo inotungamira cylindrical pamusoro pevharuvhu yetsono uye muviri wejekiseni haifanirwe kuve nekukuvadza kuri pachena kwekukwenya uye zvikwambo, uye yekuvharisa koni kumusoro kwapera.

3.2 Isa vharafu yetsono panzvimbo ye 45 °, dhonza valve yetsono kunze kwemuviri wevharuvhu neinenge 1/3, uye inogona kutsvedza zvishoma nezvishoma mumutumbi wevharuvhu pasi pekuita kwehuremu hwayo pasina chero chinhu chinonamatira.

3.3 Isai jekiseni remafuta rakaunganidzwa pane jekiseni remafuta, uye gadzirisa kudzvanya kwechitubu kwakakwira zvishoma pane yakajairwa kuvhura jekiseni remafuta ejekiseni remafuta (kazhinji 12~14MPa yakakwirira kupfuura 3~5MPa).Kana dzvinyiriro yeoiri ikakwira kusvika pa20MPa, yera nguva inotora kuti mafuta adzike kubva pa20MPa kuenda ku18MPa, kwete pasi pe9 ~ 12s.

Zvikasadaro, kuita chisimbiso kwakashata, uye hapafanirwe kunge paine madonhwe emafuta ari pachena akatenderedza gomba remhuno.Kana pasina mafuta injector tester, iyo yakagadziridzwa jekiseni yemafuta inogona kuiswa yakananga papombi jekiseni remafuta ejini yedhiziri yekuongororwa.

3.4 Gadzirisa kune yakataurwa mafuta jekiseni kumanikidzwa kwe12MPa, uye pombi yemafuta pakumhanya kwepombi kunosvika makumi matanhatu kusvika makumi manomwe nguva/min.Mafuta akapfapfaidzwa anofanirwa kuve akatsetseka uye akaenzana atomu, uye panofanira kuva neruzha uye nepakati kurira.Iko hakuna kudonha kwemafuta chiitiko, uye hapana chakakomba kuvuza kwakatenderedza gomba remhuno yemuviri wejekiseni.

Isa bepa jena 10 ~ 20cm kubva pamhuno pasi pejekitari, woyera chinhambwe h kubva pamuromo kusvika paruvara rweoiri uye dhayamita d yemavara emafuta.Wobva waverenga maererano neformula.

Tsvaga kona kubva kune trigonometric basa, uye kaviri kona ndiyo kona yemafuta jekiseni.Kana zvinodiwa zvisingakwanisi kuitwa kuburikidza nebasa riri pamusoro apa, jekiseni itsva yemafuta inofanira kutsiviwa.

Pakupedzisira, zvinotevera zvinofanira kucherechedzwa:

(1) Teerera kune iri pamusoro kodhi paunenge uchishandisa jekiseni remafuta kuti usashandise zvisizvo.Kana zvisina kudaro, izvo zvinodiwa hazvizowaniki, mafuta achave asina kupiswa kana kuti asina kupiswa, utsi hutema huchabudiswa kubva mukuneta, mafuta achaparadzwa, uye simba richakanganiswa.

(2) Kana uchigadzirisa kudzvanywa kwejekiseni remafuta, usamborega ganda kana zvigunwe zvichiuya pedyo neburi remuromo uye kubaiwa nejekiseni.Nekuda kwekuti mafuta edhiziri akakwira anopinda mukati meganda oyerera achipinda mutsinga dzeropa, zvinova zvine chepfu pamuviri wemunhu.Kunyanya kutarisisa kunofanirwa kubhadharwa kuti usambocherekedza mamiriro ejekiseni remafuta zvakanyanya kudzivirira kukuvadzwa kwemeso.
