I-Diesel Fuel Injector entsha 28490086 ye-Jmc Transit Qingling

Izitofu zamafutha eziinjini zedizili ezinesantya esiphezulu esiphakathi nezincinci zineendidi ezimbini ngokubanzi: uhlobo lwepintle kunye nohlobo olunemingxuma. Iinaliti ze-axial zisetyenziswa kwi-vortex okanye kumagumbi okutsha kwangaphambili. Inani lemingxuma yokutofa yi-1, kwaye i-diameter yokuvula ingaphezulu kwe-1mm. Olu hlobo lwe-injector lusebenza ngokuthembekileyo, kwaye imingxuma yokujova ayilula ukuba ivalwe yi-carbon deposits, kodwa ukusebenza kakuhle kwe-thermal kuphantsi kwaye ukusetyenziswa kwepetroli kuphezulu. Iinjini zedizili zasekhaya eziyi-125 kunye neenjini zedizili eziyi-146 zolu didi. Izitofu ezinemingxuma emininzi zisetyenziswa kumagumbi okutsha ngokutofa ngokuthe ngqo. Iyakwazi ukutshiza izitshizi ezininzi nge taper encinci kunye noluhlu olude. Olu hlobo lwe-injector lunokusebenza okuphezulu kwe-thermal kwaye luyonga kakhulu amafutha. I-injector yamafutha ye-injini ye-diesel yasekhaya ye-135 inemingxuma emininzi ye-nozzle kunye nobubanzi be-0.35mm. Ivalve yenaliti edityanisiweyo yesitofu samafutha ichanekile noko, kwaye ukukhutshwa kwayo okuhambelanayo yi-0.002 ~ 0.004mm kuphela. Ukuba kukho ukungcola kwioli ye-diesel, ivalve yenaliti iya kuxinga. Ukongezelela, intloko ye-injector ye-fuel idibene ne-high-temperature kunye ne-high-pressure gas kwigumbi lokutshisa ixesha elide, ibangela ukuba i-valve yenaliti ikhule ngokuthe ngcembe kwaye iguqule, kwaye ichaphazele ukusebenza okuqhelekileyo kwe-locomotive. Xa i-injector isebenza, indawo yokutywina yomzimba wevalve yenaliti isoloko ichaphazeleka yivalve yenaliti, idityaniswa nenaliti eqhubekayo yokuphuma kweoyile yoxinzelelo oluphezulu ukusuka kule ndawo, umphezulu wecone uya kubonakala imikrwelo kunye namabala - kancinci kancinci ulahlekelwe ukutywina, kwaye uqalise ukuthontsiza ioli. Xa ubushushu bomatshini buphantsi, umbhobho wokukhupha umsi uya kukhupha umsi omhlophe, yaye xa ubushushu bomatshini buphakama, bujika bube ngumsi omnyama, yaye ngamanye amaxesha umbhobho wokukhupha umoya uya kukhupha izandi ezingaqhelekanga zokuqhushumba.
