Isitofu se-Diesel Fuel Injector 0445110668 Bosch for Cummins/Foton

Jonga kwaye uhlengahlengise isitofu samafutha

I-injector yamafutha kufuneka ihlolwe kumvavanyi okhethekileyo. Ukuthontsiza kombhobho kufuneka kuhlolwe xa kulungiswa i-injector. Uxinzelelo lwenaliti ye-injector luhlengahlengiswa ngokuqhelekileyo, kwaye ukukhangela umgangatho we-atomization ufanelekile. Lungisa ipompo yoxinzelelo lweoyile yomvavanyi ukuya kwi-1-2 MPa ephantsi kunoxinzelelo olumiselweyo lwenaliti, kwaye uyigcine ngaphezulu kwe-10s. Ngeli xesha i-oil nozzle kufuneka ingabi neoli. Ukuba kukho ukuvuza kwe-oyile kunye nesenzeko esimanzi, oko kuthetha ukuba ukutywinwa kwendawo yokutywinwa kweconical kubi kwaye kufuneka kudityaniswe nokusila okanye ukutshintshwa. Xa ulungelelanisa i-injector, indlela yokukhangela inani le-oyile yokubuya kukuqala ukulungelelanisa uxinzelelo lwe-injector ukuya kwi-8 ~ 10 MPa ephezulu kunoxinzelelo oluchaziweyo, kwaye emva koko ushukumise isibambo se-oyile yepompo, ukwenzela ukuba uxinzelelo lomhloli luphakame. ukuya kwi-4 ~ 5 MPa ngaphantsi kwexabiso loxinzelelo olungentla. Ngeli xesha, jonga ixesha elifunekayo xa uxinzelelo kwigeyiji yoxinzelelo lwehla ukuya kwi-2MPa. Ukuba ixesha lokuhla liphakathi kwe-10 kunye ne-20 imizuzwana, kufanelekile. Ukuba ixesha lifutshane kakhulu, oko kubonisa ukuba ucoceko phakathi kwevalve yenaliti kunye nomzimba wevalvu mkhulu kakhulu, okanye umzimba wevalve yenaliti kunye nesiphelo esisezantsi se-fuel body joint joint surface sealing ayingqongqo, kufuneka itshintshwe injini yedizili. ukuthembeka kwevalvu, ukuqina kuchaphazela ngqo ubomi benjini yedizili. Umonakalo wokuxinana komoya uya kuchaphazela umsebenzi wenjini yedizili. Ilahleko ebangelwa kukwaphuka kwevalve ingaphezulu lee kunexabiso levalve ngokwayo, kwaye isiphumo sibi kakhulu.
