Ikhwalithi Ephakeme I-Common Rail Diesel /Fuel Injector NozzleDLLA148P062

Ukuhlaziywa kokuthi kungani umlomo womjovo ubhajwe kuzijovo. (ingxenye 3)

2.3.2 Ukuqina kobuso bombhobho ngu-720HV1～780HV1, ukujiya kongqimba lwe-carburized ngu-0.6mm～0.8mm, futhi i-austenite egciniwe akumele idlule u-15%. Ubulukhuni bobuso benombolo yesitembu sensimbi yokuqala ye-HHM nozzle yi-HV0.2588, ephansi kakhulu kunezidingo zokuklama, ubukhulu bengqimba ye-carburized yi-0.6mm, izinga le-martensite liyi-2, futhi i-austenite egciniwe iyileveli 1; ubulukhuni bobuso benombolo yesitembu sokuqala se-HD nozzle buphansi ku-HV1615 Ngokwezidingo zokuklama ze-HV1720, ubukhulu bengqimba ye-carburized yi-0.86mm, izinga le-martensite liyizinga lesi-4, kanti izinga le-austenite eligcinwe liyizinga lesi-3. . Ubulukhuni bembobo yangaphakathi yamabhomu amabili abuzange buhlangabezane nezidingo zokuklama. Impahla ye-valve yenaliti i-W6Mo5Cr4V2, izinga likazwelonke lidinga ukuthi okuqukethwe kwe-C kube ngu-0.8% kuya ku-0.9%, futhi okuqukethwe kwe-V kube ngu-1.75% kuya ku-2.20%. Inombolo yesitembu sokuqala esilinganisiwe se-HD yokuqukethwe kwe-valve yenaliti engu-0.7%, okuqukethwe kwe-V kungu-1.09%, futhi okuqukethwe kwe-C no-V kuphansi kunezidingo ezijwayelekile zikazwelonke;

2.3.3 Okuqukethwe kwe-C kwenombolo yesitembu sokuqala se-HHM valvu yenaliti ngu-0.72%, okuqukethwe kwe-V kungu-1.19%, futhi okuqukethwe kwe-C no-V kungaphansi kunezidingo ezijwayelekile zikazwelonke. Ezinye izakhi ze-alloy zevalve yezinaliti ezimbili zingaphakathi kwebanga elidingwa yizinga likazwelonke. I-nozzle ye-nozzle ingu-18Cr2Ni4WA, okuqukethwe kwe-C kwenombolo yesitembu sokuqala se-HD nozzle ngu-0.20%, futhi izinga likazwelonke lidinga u-0.13% kuya ku-0.19%, futhi okuqukethwe kwezinye izingxenye ze-alloy ze-nozzle kungaphakathi kwebanga. edingekayo ngokwezinga likazwelonke. Zonke izakhi ze-alloying zenombolo yesitembu sensimbi sokuqala i-HHM nozzle zingaphakathi kwebanga elidingwa yindinganiso kazwelonke.
