Rail Rail Common F00VC01015 Mo te Diesel Injector 0445110059 mo te ngira werohanga

"Tauira whakataurite" te hanganga whakarewa: he ferrite te hanganga whakarewa o te paraka pokekore.

Whakatauhia te puna o te parai parakore whakarewa ma te whakataurite tauira.

"Tauira whakataurite" te hanganga whakarewa: he ferrite te hanganga whakarewa o te paraka pokekore.

Ko te hanganga metallographic o te "tauira whakatairite" e whai ake nei:

A.Ko te hanganga metallographic o te tinana papu o te papu teitei-pēhanga heα otinga totoka + acicular eutectic silicon;

B. Ko te hanganga whakarewa o te plunger, ko tona hanganga metallographic he martensite + granular carbide;

C. Ko te hanganga metallographic o te ringaringa plunger, ko te hanganga metallographic mata he martensite + pupuri austenite;

D. Ko te anga whakarewatanga o te anga injector, he pearlite wariu + nui me te ferrite reticular.

E. Ko te hanganga metallographic needle valve, he martensite + band tona hanganga metallographic

F. Ko te hanganga metallographic o te tinana takirere ngira, tona hanganga metallographic he martensite + granular carbide;

G. Ko te hanganga whakarewa o te ngongo pehanga teitei he ferrite.

Na roto i te whakataurite i runga ake nei, ko te hanganga metallographic o te putorino hinu pehanga teitei he rite ki tera o te aukati parakore whakarewa, he ferrite enei e rua, e whakaatu ana kua wehea te aukati mai i te paipa hinu pehanga teitei, katahi ka whakatau i te te puna o te aukati parakore whakarewa. Ka mutu, ko te whakaaro ko te wa e whirihora ana i te punaha whakangao hinu hinu, me kaha te whakakore me te horoi o nga paipa wahie pehanga teitei e whakamahia ana, me nga hua pai kua tutuki.

Na te whanaketanga tonu o te ohanga maakete me te kaha ake o te whakataetae maakete, ko te hua me te kaha whakataetae me whai tohu mahi pai hei taapiri atu ki nga utu utu, me te mea nui ake, me whai tohu tino pono me te iti o te reiti kore e whakamahia ana. Na reira, ko te whakapai ake i te taumata pono o nga hua ko te hiahia o te whakataetae maakete me tetahi o nga tikanga mo nga hua kia whakataetae.
