I-Diesel Injector Fuel Injector 095000-6395 Denso Injector yeGmc, Isuzu

Ngokunyuka koburhabaxa bodonga lwangaphakathi lombhobho, amandla omngxuma ngaphakathi kumbhobho ayancipha, ngakumbi kwindawo yokuphuma yombhobho, ngakumbi ngenxa yokuba umngxuma wombhobho uthunyelwa ezantsi, umaleko womngxuma. ichaphazeleke ngobunzima bodonga, kwaye i-cavitation iphukile kwaye yawa.

Ngokunyuka koburhabaxa bodonga lwangaphakathi lombhobho, amandla e-kinetic enesiphithiphithi ngaphakathi ngaphakathi komlomo ayanda, ngakumbi kwindawo yokungena emlonyeni, amandla e-kinetic yeyona inkulu, ngakumbi ngenxa yokuba i-chamfer ebukhali ekungeneni kwe-nozzle. umlomo wombhobho wongeza ubunzulu besiphithiphithi ekungeneni komlomo.

Phantsi kwemeko yoxinzelelo lwenaliti ephantsi (30MPa), ukwandisa uburhabaxa bodonga lwangaphakathi lombhobho kunefuthe elincinane kwisantya sokuhamba kobunzima kunye nesantya esiphakathi sombhobho wokuphuma.Nangona kunjalo, phantsi kwemeko yoxinzelelo oluphezulu lwenaliti (i-180MPa), ngokunyuka koburhabaxa, isantya sokuhamba kobunzima bokukhutshwa kombhobho sinyuka kancinci, kwaye isantya esiphakathi sokuphuma siyehla kancinci, ngakumbi ngenxa yoburhabaxa bodonga lwangaphakathi. umbhobho wandisa ilahleko ngexesha lenkqubo yokuhamba.Phantsi kweemeko zoxinzelelo oluphezulu lwejethi, amandla aphazamisayo ekuphumeni komlomo anyuka ngokukhawuleza ngokunyuka koburhabaxa, ngeli lixa isiphithiphithi soxinzelelo kwindawo yokukhupha sinyuka kancinci phantsi koxinzelelo lwenaliti ephantsi.

Ubukhulu besiphithiphithi ekuphumeni komlomo sisecaleni kwe-axis engu-X ukusuka kumzantsi womlomo ukuya kudonga olungaphezulu lombhobho obonisa intsingiselo yokuqala usiba mncinci uze unyuke, ukuqina kwesiphithiphithi kwindawo esembindini womlomo incinci, kunye ne-turbulence intensity in the top wall cavitation layer of the nozzle is big, kunye ne-fragmentation ye-cavitation iphakamisa ukuphazamiseka kwesiphithiphithi kwindawo yodonga ngaphezu kwe-nozzle outlet, leyo ikhuthaza ukunyanzeliswa kwe-turbulence.
