I-Diesel Injector Fuel Injector 095000-6395 Denso Injector ye-Gmc, Isuzu

Ngokukhula kokuqina kodonga lwangaphakathi lombhobho, amandla embobo ngaphakathi ku-nozzle aba buthaka, ikakhulukazi endaweni yokuphuma ye-nozzle, ikakhulukazi ngoba ungqimba lwembobo ku-nozzle luhanjiswa phansi, ungqimba wembobo ithinteke ngobunzima bodonga, futhi i-cavitation iphukile futhi iwa.

Ngokukhula kokuqina kodonga lwangaphakathi lombhobho, amandla e-kinetic anesiphithiphithi ngaphakathi ku-nozzle ayanda, ikakhulukazi endaweni yokungena ye-nozzle, amandla e-kinetic makhulu, ikakhulukazi ngoba i-chamfer ebukhali emnyango we-nozzle. umlomo wombhobho uthuthukisa ukushuba kwesiphithiphithi emnyango wombhobho.

Ngaphansi kwesimo sokucindezela komjovo ophansi (30MPa), ukukhulisa ubuhwaqaqe bodonga lwangaphakathi lombhobho kunomphumela omncane esilinganisweni sokugeleza kwesisindo kanye nesivinini esimaphakathi sokukhipha umlomo wombhobho.Kodwa-ke, ngaphansi kwesimo sokucindezela okuphezulu komjovo (180MPa), ngokwanda kokuqina, izinga lokugeleza kwenqwaba ye-nozzle likhuphuka kancane, futhi isivinini esimaphakathi sokuphuma siyancipha kancane kancane, ikakhulukazi ngenxa yobulukhuni bodonga lwangaphakathi. umlomo wombhobho wandisa ukulahlekelwa phakathi nenqubo yokugeleza.Ngaphansi kwezimo zokucindezela kwendiza ephezulu, amandla anyakazayo ekuphumeni komlomo akhuphuka ngokushesha ngokunyuka kokuqina, kuyilapho ukushuba kwesiyaluyalu endaweni yokuphuma kukhuphuka kancane ngaphansi kwengcindezi ephansi yomjovo.

Ukuqina kwesiphithiphithi lapho kuphuma khona imbobo kuhambisana ne-axis engu-X ukusuka phansi kwembobo kuya odongeni olungaphezulu lwembobo okubonisa ukuthambekela kokuqala ngokuba mncane bese kukhuphuka, ukushuba kwesimo endaweni ephakathi nendawo okuncane kakhulu, kanye nokuqina kwe-turbulence endaweni engaphezulu yodonga lwe-cavitation layer ye-nozzle inkulu, futhi ukuhlukaniswa kwe-cavitation kuthuthukisa ukuphazamiseka kwe-turbulent endaweni yodonga ngaphezu kwe-nozzle outlet, okubuye kukhuthaze ukushuba kwe-turbulence.
