Tsis ntev los no, cov kws tshaj lij kev lag luam tau tshaj tawm cov lus qhia muaj cai rau kev xaiv cov roj cav rau Cummins QSB6.7 series diesel xyaw uas nrov heev, sib txuas cov khoom siv thawj cov chaw tsim khoom tshwj xeeb nrog cov ntaub ntawv ua haujlwm. Lub cav no yog siv dav hauv kev tsim kho tshuab, tshuab tsim hluav taws xob, tsheb mining, thiab lwm yam kev siv, thiab kev xaiv roj cav ncaj qha cuam tshuam rau cov khoom siv lifespan thiab cov nqi khiav lag luam.
1. Daim Ntawv Pov Thawj Cov Khoom Siv Tseem Ceeb: Peb Cov Qauv Tseem Ceeb yog qhov tseem ceeb
Raws li Cummins phau ntawv qhia kev qhia thiab cov ntaub ntawv xov xwm, cov roj cav sib xws nrog QSB6.7 yuav tsum ua tau raws li peb daim ntawv pov thawj:
Qib Kev Ua Haujlwm: API CK- 4 qib roj zoo dua. Cov roj no tau sib xws nrog tom qab- cov kev kho mob xws li EGR (Exhaust Gas Recirculation) thiab SCR (Selective Catalytic Reduction), thiab muaj 30% zoo dua los tiv thaiv -oxidation thiab tiv thaiv- hnav kev ua tau zoo dua li cov roj qib CH-4. Cov cav qub qub tuaj yeem raug txo qis rau qib API CH-4, tab sis lub sijhawm hloov roj yuav tsum tau luv. Viscosity Matching: SAE 15W-40 qib viscosity raug pom zoo rau kev ua haujlwm ntawm -5℃thiab 40 degree. Nyob rau hauv ib cheeb tsam uas tsis kub (qis dua -5 degree), hloov mus rau 10W-30 viscosity los tiv thaiv khaub thuas pib hnav.
Factory Specifications: Yuav tsum ua raws li Cummins CES 20071/20072 thiab lwm yam qauv ntawm lub Hoobkas. Qee tus qauv siab - kawg yuav xav tau CES 20081 ntawv pov thawj.
2. Kev Ua Haujlwm Kev Kho Kom Zoo: Cov kev daws teeb meem tshwj xeeb rau cov xwm txheej tshwj xeeb
Cov kws tshaj lij muab cov lus pom zoo meej rau cov ntawv thov QSB6.7:
Kev Siv Tshuab (Excavators/Loaders): Siv Cummins Blue Supreme CK-4 15W-40 cav roj. Nws cov qauv ntau theem pom tuaj yeem cais cov impurities loj dua 10μm, ua rau nws haum rau cov chaw siv plua plav.
High -altitude generator sets: Siv ACEA E3/E5 certified oil for enhanced resistance to high-kub oxidation, haum rau kev khiav hauj lwm qhov siab tshaj 2000m.
Txias- thaj av mining tsheb: Siv 10W-30 qhov ntsuas kub qis nrog lub ncuav taw tes qis li -35 degree, kom ntseeg tau tias pib du.
3. Pitfall Avoidance Guide: Cov yuam kev no ua rau koj cov khoom puas tsuaj
Kev sib xyaw cov roj ntawm cov qib API sib txawv (piv txwv li, CH-4 thiab CK-4) raug txwv nruj, vim nws tuaj yeem ua rau sludge blockage.
Tsis tu ncua diesel cav roj tsis tuaj yeem siv rau qhov chaw ntawm cov roj tsheb ciav hlau; siab -siab cov kab tsheb ciav hlau yuav tsum muaj roj nrog kev huv dua.
Lub sijhawm hloov roj yuav tsum tsis txhob ncua ntev; nyob rau hauv hnyav- lub luag haujlwm hnyav, nws raug nquahu kom hloov txhua 200 teev.
4. Cov Khoom Siv Tseem Ceeb Guarantee: Cov Txheej Txheem Txheej Txheem Txhawb
Tam sim no, Cummins sib koom ua lag luam hauv Chongqing thiab Dongfeng tau tsim cov khoom siv dav dav. Blue Supreme series roj cav hauv 18L thiab 200L qhov ntau thiab tsawg tuaj yeem xa tuaj tsis pub dhau 15 hnub ua haujlwm. Peb kuj muab cov kev pabcuam kuaj roj, siv cov qauv ntsuas roj los kwv yees cov khoom hnav.
