I-New Injector Nozzle Dlla157p1424 0433171886 OE Me 226718 Me222914 for Fuel Injector 0445120048

1. Igebe elilinganayo lombhangqwana wevalvu yenaliti ngokuvamile liyi-2~4μm. Uma kucatshangelwa izinga langempela lokucubungula, igebe elifanelekile liyi-1 ~ 10μm ocwaningweni, ubude bendawo yokuvala ivalve yenaliti ngu-8.4mm, izinga lokungacacile kwevalvu yenaliti liziro, futhi izinga lokuthambekela linguziro. , setha ingcindezi yembobo yokungena ibe ngu-120MPa, lilingise futhi ubale izinga lokuvuza kukaphethiloli esikhaleni se-coupler ye-valve yenaliti ngaphansi kogqinsi oluhlukene lwefilimu kawoyela, njengoba ukushuba kwefilimu kawoyela kukhula, izinga lokuvuza le-coupler valve yenaliti liyakhula, futhi izinga lokuvuza liyakhula. Uma ubukhulu befilimu bungu-1μm, izinga lokuvuza lingu-0.025mL/s, futhi lapho ukujiya kwefilimu kuba ngu-10μm, izinga lokuvuza lingu-6.37mL/s, okuwukunyuka cishe izikhathi ezingu-25. Uma ifilimu kawoyela imncane, izinga lokuvuza liyashintsha ejikeni elinogqinsi lwefilimu, futhi lapho ifilimu kawoyela idlula u-6 μm, izinga lokuvuza lishintsha cishe ngokuhambisana nogqinsi lwefilimu.

2. Ubude bendawo yokuvala buyipharamitha ebalulekile yophawu lwevalve yenaliti. Ngokombono, lapho ubude bevalve yenaliti yokuvalwa kuvame ukungapheli, ukuvuza kwayo ngaphansi kwezimo ezimile kunguziro ngenxa yokungqubuzana kwe-viscous kwendawo yodonga. Ngokwenza, ngenxa yezidingo zokuklama zesakhiwo esihlangene se-injector, ubude bokuvalwa kokuhlanganiswa kwe-valve inaliti bunqunyelwe. Ngaphansi kobude obuhlukene bokuvalwa kwevalvu yenaliti enaliti, izici zokuvala zombhangqwana we-valve yenaliti, njengoba ubude bendawo yokuvalwa kwevalvu yenaliti bukhula, izinga lokuvuza lehla ngokushesha, kanye nezinga lokuvuza liyancipha.
