Umgangatho oPhezulu omtsha weDizili Injector 28229873 33800-4A710 Common Rail Injector for Delphi Hyundai 2.5 CRDI Engine Spare Parts

Yenziwe ngentsimbi yentsimbi ephezulu, i-cylindrical clearance yayo i-0.001mm-0.0025mm kuphela, efunyenwe ngomatshini ochanekileyo okanye wokugaya, kunye nokudibanisa i-fuel injector couplings ayitshintshi. Ukuba umsantsa mkhulu kakhulu, uxinzelelo lwenaliti luya kuhla kwaye umgangatho wokutshiza uya kuhla; I-gap incinci kakhulu, kwaye ivalve yenaliti ilula ukuyijam. Ikhowuni ye-annular (i-cone ethwele uxinzelelo) embindini wevalve yenaliti ibekwe kwindawo ye-oyile ye-annular yomzimba wevalve yenaliti, kwaye umsebenzi wayo kukumelana ne-axial thrust eyenziwe luxinzelelo lweoyile ukwenza ivalve yenaliti inyuke. Ikhowuni ekumzantsi wevalve yenaliti (ikhowuni yokutywina) ihambelana nomzimba wevalve yenaliti ukutywina umngxuma ongaphakathi wesitofu.

Inxalenye ephezulu yevalve yenaliti inegxalaba le-convex, xa ivalve yenaliti ivaliwe, umgama h phakathi kwegxalaba kunye nobuso besiphelo esisezantsi somzimba we-injector kukuphakanyiswa okuphezulu kwevalve yenaliti, kwaye ubungakanani bayo bumisela inani inaliti yamafutha, ngokubanzi H=0.4mm-0.5mm. Kukho i-1-2 yokubeka izikhonkwane ezi-8 ekudibaneni komzimba wevalve yenaliti kunye ne-injector yokuthintela umzimba wevalve yenaliti ukuba ujikeleze ukuphepha ukungahambi kakuhle kwe-oyile yokungena.

Xa i-injector isebenza, idizili yoxinzelelo oluphezulu olusuka kwimpompo ye-injector, ngombhobho we-oyile ngokudibeneyo kwi-oyile yokungena kwindawo yokutofa emzimbeni, emva koko ingene kumngxuma oyile we-annular kumbindi wevalufa yenaliti, isebenza kuxinzelelo. -i-cone ethwele i-valve yenaliti, eyenza i-axial thrust ephezulu kwivalve yenaliti, xa oku kutyhala kukhulu kunoxinzelelo lwangaphambili lwe-spring yesilawuli se-injector; ivalve yenaliti inyuka ngokukhawuleza, ivule umngxuma wokutofa, kwaye i-high-pressure fuel fuel ifakwe ngokukhawuleza kwigumbi lokutsha. Xa ipompo yokutofa i-fuel iyeka ukubonelela ngeoyile, uxinzelelo kwipaseji ye-oyile yoxinzelelo oluphezulu lwehla ngokukhawuleza, kwaye ivalve yenaliti ibuyela kwindawo ngexesha phantsi kwesenzo soxinzelelo olulawula intwasahlobo, kwaye umngxuma wokutofa uvalwe ukumisa i-fuel. isitofu.

Isibambiso esincinci sedizili esingena kumngxunya we-oyile wonyaka womzimba wevalufa yenaliti uqukuqela ukuya kuxinzelelo olulawula ukuphela kwentwasahlobo ngomsantsa ophakathi kweendawo zokukhwelana zesibini sokutofa, singene kumbhobho wokubuyisela ioyile, kwaye uqukuqela ubuyela kwisihluzo, esetyenziselwa ukuthambisa isibini sokutofa amafutha.

Uxinzelelo lokuvula (uxinzelelo lwe-injection) lwe-valve yenaliti luxhomekeke ekulayisheni kwangaphambili kwentwasahlobo yokulawula. Ii-injini ezahlukeneyo zineemfuno ezahlukeneyo zoxinzelelo loxinzelelo lwenaliti, ezinokuthi zihlengahlengiswe sisikrufu sokulawula uxinzelelo, uxinzelelo luyenyuka xa lujijelwe ngaphakathi kwaye luyancipha xa lukhutshiwe.
