Cummins QSNT855 Cav Sib Tsoo
Porduct daim ntawv thov
NTA855 muaj ntau yam siv.Nws tuaj yeem nruab nrog cov khoom siv hluav taws xob.Piv txwv li, nws tuaj yeem nruab nrog lub tshuab hluav taws xob teeb rau cov nkoj.Nws tseem tuaj yeem nruab nrog tsheb.Yog hais tias nruab nrog tsheb, nws yog tsuas yog siv machinery, bulldozers, excavators, cranes, thiab lwm yam.
Advanced tsim thiab txhim khu kev qha kev ua tau zoo:
Lub tog raj kheej thaiv: ua los ntawm high-strength alloy cam khwb cia hlau, nrog zoo rigidity, tsis tshua muaj kev co thiab tsis muaj suab nrov.
Lub taub hau lub tog raj kheej: Plaub-valve tsim ib lub tog raj kheej, optimized huab cua / roj sib tov sib piv, zoo txhim kho combustion thiab emissions;ib lub taub hau ib lub tog raj kheej, kho yooj yim.
Camshaft: Tus qauv camshaft ib leeg tuaj yeem tswj tau lub valve thiab lub sijhawm txhaj tshuaj, thiab qhov ua kom zoo tshaj plaws cam profile tuaj yeem txo qhov cuam tshuam quab yuam thiab txhim kho kev ntseeg tau thiab kav ntev.
Crankshaft: Integral crankshaft ua los ntawm high-strength forged steel.Cov txheej txheem induction hardening ntawm fillet thiab phau ntawv journal tuaj yeem ua kom muaj zog dua lub zog ntawm lub crankshaft.
Piston: Siv cov cuab yeej siv thev naus laus zis tshiab tshaj plaws, kev tsim ntawm ω-puab lub taub hau thiab lub kaus mom-puab tiab tuaj yeem them nyiaj rau thermal expansion thiab contraction kom zoo.
Tam sim no peb coj NTA855-G1 ua piv txwv, txheeb xyuas qhov tshwj xeeb ntawm lub cav no
