KTA38 QSK38 Diesel Cav Cov Kab Mob Txhawb Nqa Kev Coj Cummins

SAE 4340 chromium-molybdenum hlau yog forged raws li tag nrho thiab undergoes carburnising quenching thiab tsawg-kub kev kho mob. Nws lub zog tensile tsis tsawg tshaj 1200MPA, thiab lub hardness tuaj yeem ncav cuag mus rau hrc 50 - 55. Qhov no yog 65% siab dua li ntawm lub nrag khawm hlau nkhaus. Cov khoom yoog xa mus rau lub cav lub siab-torque (tus nqi siab ntawm 1800n-m) thiab high-rpm (1500r \/ min) cov haujlwm ua haujlwm.

Nrog ntau-tav toppology tsim qauv, cov tuab ntawm cov key-cov kabmob thaj tsam yog nce rau 15 hli. Tom qab 1 {{0 0, {{{} lub sij hawm kev xeem qib siab (nrog ib qho kev co ntawm 200zz), qhov deformation tsis loj dua 0.03mm. Qhov no siv tau zoo rau crankshaft system nvh (suab nrov, kev co, thiab acoustic kev co harshness) teeb meem.

Sab nraub qaum ntawm lub bracket yog tsim nrog honeycomb kub dissipation qhov. Ua ke nrog cov saum npoo txhuas plating txheej txheem (nrog ib tuab ntawm 20μm), nws txhim kho cov cua sov dissipation efficiency los ntawm 40%. Nyob rau tib lub sijhawm, nws tuaj yeem tiv thaiv cov ntsev txau kom txog li 2, {3}}}}}}}}}}}} }es thiab ntug hiav txwv engineering.

Sab hauv cov kabmob sib tiv tauj nyob npoo npoo yog daim iav polished (nrog cov reepness ra tsis loj dua li {}}

Cov tshuab hluav taws xob tau tsim: Ciav rau QSK38 Series Diesel Generator teeb (650-1350 kw). Nws tuaj yeem lav qhov ruaj khov ntawm crankshaft system hauv 98% thauj khoom thiab txo cov tshuab hluav taws xob hloov pauv tau tshwm sim los ntawm kev co (hauv 0. 5%).

Cov kev siv tshuab: Siv rau hauv cov pob tseg tsuas nrog KTA38 cav, nws tuaj yeem tiv taus cov kev coj ua kom poob siab thiab ua kom tiav cov sijhawm hloov mus rau 2 xyoos lossis 8000 teev.

Marine Hwj Chim: sib phim nrog cov tub rog tsim hluav taws xob, dhau IP23 tiv thaiv daim ntawv pov thawj, yoog raws ib puag ncig thiab ntsev txau kho corrosion.

Economic Kev Txhim Kho: Los ntawm cov kev txhawb nqa cov txheej txheem txheej txheem thiab cov khoom hloov kho dua tshiab, {} Yuan (raws li 4, {3 teev} sijhawm ua haujlwm txhua xyoo).

Cov ntse ua tau zoo: cov ntaub ntawv qub yog ua ntej-thauj mus rau hauv Cummins Acite Depracket kev ntseeg siab hauv lub sijhawm. Tus pib qhov tseeb tus nqi ntawm cov lus ceeb toom tshaj tawm spn 5278-18 (cov kabmob overload) yog tsis tsawg dua 95%.
