IValve kaloliwe eqhelekileyo F00VC01015 ye-Diesel Injector 0445110059 yeNaliti yokutofa

"Isampulu yokuthelekisa" isakhiwo se-metallographic: isakhiwo se-metallographic yebhloko yentsimbi yokungcola yi-ferrite.

Misela umthombo wokuvala ukungcola kwesinyithi ngokuthelekisa isampuli.

"Isampulu yokuthelekisa" isakhiwo se-metallographic: isakhiwo se-metallographic yebhloko yentsimbi yokungcola yi-ferrite.

Ulwakhiwo lwe-metallographic "yesampuli yokuthelekisa" lulandelayo:

A.Ubume bemetallographic bomzimba wempompo yempompo yoxinzelelo oluphezuluα isisombululo esiqinileyo + i-silicon ye-acicular eutectic;

B. Isakhiwo se-metallographic ye-plunger, isakhiwo sayo se-metallographic yi-martensite + granular carbide;

C. Isakhiwo se-metallographic somkhono we-plunger, isakhiwo se-metallographic esiphezulu yi-martensite + igcinwe i-austenite;

D. Ulwakhiwo lwe-metallographic yeqokobhe lokutofa, elinepearlite egqabhukileyo + enkulu kunye ne-reticular ferrite.

E. Inaliti yevalve metallographic isakhiwo, isakhiwo sayo metallographic yi martensite + band

F. Isakhiwo se-metallographic somzimba wevalve yenaliti, isakhiwo sayo se-metallographic yi-martensite + granular carbide;

G. Isakhiwo se-metallographic setyhubhu ephezulu yoxinzelelo yi-ferrite.

Ngokuthelekisa oku ngasentla, ulwakhiwo lwe-metallographic lombhobho we-oyile woxinzelelo oluphezulu luhambelana nelo lokuvalwa kokungcola kwesinyithi, zombini ziyi-ferrite, ebonisa ukuba ukuvaleka kuvaliwe kumbhobho weoyile woxinzelelo oluphezulu, kwaye emva koko imisela umthombo wokuvaleka kokungcola kwesinyithi. Ekugqibeleni, kucetyiswa ukuba xa uqwalasela inkqubo yokubonelela nge-diesel fuel, ukuchithwa kunye nokucoca imibhobho yepetroli ephezulu esetyenzisiweyo kufuneka iqiniswe, kwaye iziphumo ezilungileyo zifunyenwe.

Ngophuhliso oluqhubekayo loqoqosho lwemarike kunye nokuqiniswa kokhuphiswano lwemarike, imveliso enokhuphiswano oluqinileyo kufuneka ibe nezalathisi zokusebenza ezigqwesileyo ukongeza kwimiba yexabiso, kwaye okona kubaluleke kakhulu, kufuneka ibe nezalathi ezithembekileyo ezibalaseleyo kunye namazinga asezantsi okusilela ekusetyenzisweni. Ke ngoko, ukuphuculwa kwenqanaba lokuthembeka kweemveliso yimfuneko yokhuphiswano lwentengiso kunye nenye yezinto ezifunekayo ukuze iimveliso zikhuphisane.
