Inyector ye-Diesel Common Rail Injector 20R8968 yombungu c9 injini yeCat Excavator Spare Parts

Uphando ngeMpembelelo yoMlomo wombhobho wesitofu Intshukumo yeNjini yeDizili kwiiMpawu zokuTofwa kumngxuma ngamnye (inxalenye yesi-3)

(3) Ukuhamba kwe-cavitation kwi-nozzle ye-nozzle kunempembelelo ebalulekileyo kwi-jet atomization ngaphandle komngxuma we-nozzle.I-Euler-Eulerian indlela yokulinganisa i-fluid emibini ye-cavitation flow ngaphakathi kwi-nozzle ye-injector ye-multi-hole kunye ne-Lagrang ye-nozzle outlet isungulwe.Imodeli edityanisiweyo yendlela yokulinganisa i-droplet yokutshiza ye-oyile yemihla ngemihla.Imodeli ngokungathanga ngqo idibanisa izisombululo zamanani ezibini ezahlukeneyo zesigaba esiqhubekayo kunye nesigaba esicacileyo, ukuhlalutya ngokufanelekileyo ulungelelwaniso phakathi kokuhamba kwangaphakathi kunye ne-atomization yamafutha.Ngokusebenzisa ibhentshi yovavanyo yeempawu zenaliti yamafutha kumngxuma ngamnye kunye nebhentshi yovavanyo lokutshiza ngokusekwe kwindlela ye-schlieren, iimpawu zenaliti yamafutha ezifana nesantya sokutofa kwepetroli kunye nomthamo wenaliti yomjikelo womngxuma ngamnye, kunye nesitshizi esikhulu esifana nokungena kokutshiza. umgama womngxuma ngamnye wafunyanwa ngokulandelelanayo.iimpawu, kwaye yaqinisekisa imodeli yokubala yamanani esekiweyo.Iziphumo zibonisa ukuba amaxabiso afanekisiweyo kunye novavanyo akwisivumelwano esihle, isantya sokutofa kunye nomgama wokungenwa wesitshizi wemingxuma esezantsi yombhobho mkhulu kunemingxunya engaphezulu, kwaye uphuhliso lwe-cavitation lwemingxuma yomlomo esezantsi ibuthathaka.
(4) Ngokusekwe kwithiyori yobuchwephesha bezinto eziphathekayo, i-elastic mechanics kunye ne-elasticity linear, i-nozzle ye-Injector ithathwa njenge-cantilever beam, ukuguqulwa kwentloko ye-injector ye-nozzle kubalwa ngokusebenzisa ithiyori yokuguqulwa kwe-goba ye-beam, kunye no-elasticity umbhobho wesitofu usekwe ngokusekelwe kuhlalutyo lwamandla omlomo wesitofu.
