Umgangatho oPhezulu weValve yoLawulo lukaLoliwe oluPhakamileyo lweSeti iNdibano F00RJ01533 ye-Diesel Injector 0445120063

Indlela yokuhlola ivalufa yenaliti yesitofu
(1) Uvavanyo lokuqina kwentamo.Sebenzisa ioli edibeneyo okanye i-20 # ioli ye-diesel elula, kwaye usebenzise indlela yokunciphisa ukuphumeza kwibhentshi ekhethekileyo yovavanyo.Ngethuba lovavanyo, sebenzisa impompo yesandla ukuphakamisa uxinzelelo kwi-23 ~ 24 MPa kwaye ulinganise ixesha loxinzelelo lwehla ukusuka kwi-20 MPa ukuya kwi-18 MPa.Iziphumo zovavanyo kunye neemveliso eziqhelekileyo Ukuthelekisa, kufuneka kube phakathi koluhlu olufunekayo.2) Uvavanyo lokutywinwa kwesihlalo.Sebenzisa i-20 # ioli yedizili ekhanyayo kwibhentshi yovavanyo ene-accumulator yoxinzelelo, lungisa kuqala uxinzelelo lwenaliti yamafutha kuxinzelelo oluchaziweyo lwe-12.5 MPa, kwaye wandise uxinzelelo lwe-oyile nge-0.1 MPa rhoqo nge-3 ~ 5s ngokulinganayo de inaliti yamafutha iqale., ukujonga umgangatho wokutywinwa, ixabiso elincinci lokuvuza kweoli livumelekile, kwaye ububanzi bokuvuza kweoli alukho ngaphezu kwe-5mm (indawo yokuhlala ayigayi omnye komnye) okanye ububanzi buyi-3mm (indawo yokuhlala igalela omnye komnye. ).Kodwa hayi kwimilo engqukuva engqukuva.
(3) Uvavanyo lokutshiza.Sebenzisa i-20# ye-oyile yedizili ekhanyayo kwibhentshi yovavanyo, hlengahlengisa uxinzelelo lwenaliti yamafutha ukuya kwi-12.5 MPa, kwaye wenze uvavanyo lokutshiza ngama-40 ~ 80 amaxesha enaliti ngomzuzu.Umgangatho wokutshiza kufuneka uhlangabezane nezi mfuno zilandelayo: D. Isibaso esitshiziweyo kufuneka sibe neatomized.Akufunekanga kubekho amasuntswana e-oyile etshizayo kunye nokungalingani kwendawo yobukhulu obunokubonwa ngamehlo.2. Ukuqala nokuphela kwesitofu kufuneka kucace kwaye nesandi kufuneka sibe rhabaxa.3 Phambi kokuba inaliti iqale nasemva kokuba isitofu siphelile, akukho kuvuza kweoyile kuvumelekileyo kumngxuma wokutofa, kodwa ukufuma kuvumelekile.
(4) Ukutshiza ukujonga i-angle.Jonga ngeso lenyama, thelekisa i-angle yokutshiza phantsi koxinzelelo lwenaliti yamafutha esetyenziswa kwi-injini yedizili kunye nesampulu, kwaye ukutenxa phakathi komgca osembindini we-engile yokutshiza ye-injector yamafutha kunye nomgca osembindini we-injector yamafutha awukho mkhulu. ngaphezu kwe-4°30.I-engile yekhowuni yokutshiza ijongwa ngaphakathi kwe-100mm.
(5) Uvavanyo lokutyibilika.Coca ngononophelo kwaye uthambise iindawo ngeoli yedizili ehluziweyo.Xa ivalve yenaliti iku-45 ° ukuya kwindawo ethe tye, tsala ivalve yenaliti emzimbeni wenaliti nge-1/3 yobude bayo, yijike kuyo nayiphi na indawo kwaye uyiyeke.Ubunzima ngokwawo buslayida ngokukhululekileyo ngaphandle kwesithintelo.
