Fuel Injector Orifice Valve Plate 34# yeInjector 095000-5459 Engine Spare Parts

An orifice valve plate mudziyo unoshandiswa kuyera kuyerera kwechiyero, kudzikisa kumanikidzwa kana kudzoreredza kuyerera (mumakesi maviri ekupedzisira inowanzonzi restriction plate). A orifice valve plate iplate yakatetepa ine buri mairi, iyo inowanzoiswa mupombi. Kana mvura (ingave yemvura kana gasi) inopfuura nepaburi, pressure yayo inokwira zvishoma kumusoro kwegomba asi mvura painomanikidzwa kusanganidzana kuti ipfuure nepaburi, manyawi anowedzera uye mafambiro emvura anoderera. Kudzika kuzasi kwehova kuyerera kunosvika pakusangana kwakanyanya, vena contracta uko vheji inosvika pakureba kwayo uye kudzvanywa kunosvika kushoma kwayo. Kupfuura izvozvo, kuyerera kunowedzera, velocity inodonha uye kudzvinyirira kunowedzera. Nekuyera mutsauko mukudzvinyirirwa kwemvura pamatepi kumusoro nekudzika kweplate, mwero wekuyerera unogona kuwanikwa kubva kuBernoulli's equation uchishandisa coefficients akaiswa kubva mukutsvagisa kwakadzama.

Orifice valve plates anonyanya kushandiswa kuyera kuyerera kwemazinga mumapombi, kana mvura iri single-phase (panzvimbo yekuve musanganiswa wemagasi uye zvinwiwa, kana wezvinwiwa uye zvinyoro) uye yakanyatso kusanganiswa, kuyerera kunoenderera kwete kupuruzira. , iyo mvura inobata pombi yese (isingasanganisi silt kana gasi rakavharirwa), iyo inoyerera profiles yakaenzana uye yakagadziridzwa zvakanaka uye iyo fluid uye kuyerera mwero zvinosangana nemamwe mamiriro. Mumamiriro ezvinhu aya uye kana iyo orifice valve plate inovakwa uye yakaiswa zvinoenderana nemwero wakakodzera, mwero wekuyerera unogona kutariswa zviri nyore uchishandisa mafomula akadhindwa anoenderana netsvakiridzo yakakura uye yakaburitswa muindasitiri, yenyika uye nedzimwe nyika. Gorofu yevharuvhu inonzi calibrated orifice kana yakakwenenzverwa nekuyerera kwemvura kwakafanira uye mudziyo wekuyeresa kuyerera.
