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 # i-oyile 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) okanye ububanzi yi-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 esitofu ngomzuzu. Umgangatho wokutshiza kufuneka uhlangabezane nezi mfuno zilandelayo: D. Isibaso esitshiziweyo kufuneka sibe neatom. 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 kokuphela kwesitofu, 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.
