I. Ua ntej-Kev Npaj Ua Haujlwm
1. Kev soj ntsuam ib puag ncig: Tshem tawm cov khib nyiab thiab pob zeb los ntawm thaj chaw ua haujlwm, kom ntseeg tau tias qhov kev nqes hav hauv av tsawg dua lossis sib npaug li 15 degree.
Cov Khoom Siv Ua Ntej-Kev tshuaj xyuas: Txheeb xyuas cov roj lubricating qib (roj dipstick yuav tsum nyob rau hauv min-max range), qhov xwm txheej ntawm fasteners, thiab rau cov xau hauv cov kab hydraulic.
2. Cov Khoom Siv Tiv Thaiv Tus Kheej: Hnav cov hnab looj tes tiv thaiv kev poob siab, tsom iav, thiab steel- nkawm khau kev nyab xeeb.
II. Pib- thiab ua haujlwm
1. Pib-up: Internal Combustion Cav: Qhib lub roj valve, maj mam rub txoj hlua pib mus rau qhov chaw tiv thaiv, ces rub nws rov qab sai. Kaw lub choke rau qhov pib txias.
Hluav taws xob lub cev muaj zog: Pib ncaj qha nrog lub hwj chim, khiav unloaded rau 2-3 feeb.
2. Kev ua haujlwm compact: Siv txoj kev "overlapping", nrog rau pem hauv ntej thiab nram qab log lem sib tshooj ntawm 1/3 ntawm lawv qhov dav.
Txhua txheej ntawm sau yuav tsum tsawg dua los yog sib npaug li 30 cm tuab kom tsis txhob sib sib zog nqus, xoob txheej.
Kev vibration zaus yuav tsum ua tau raws li kev tsim qauv (kev sib txawv Tsawg dua lossis sib npaug rau 3Hz), thiab qhov nruab nrab amplitude Tsawg dua lossis sib npaug li 0.4 hli.
III. Kev kaw thiab tu
1. Kev kaw: Tom qab lub cav tau idled rau 3-5 feeb, tua lub solenoid hloov thiab roj Circuit Court hloov.
2. Kev tu: ntxuav cov khoom siv txhua hnub thiab xyuas cov lim cua.
Hloov cov roj cav thiab lim txhua hli, thiab ntsuas qhov vibration zaus.
IV. Kev Tiv Thaiv Kev Nyab Xeeb
Tsis yog- cov neeg ua haujlwm ua haujlwm raug txwv tsis pub nyob hauv 3-meter vojvoog ntawm cov khoom siv.
Nres lub tshuab tam sim rau kev tshuaj xyuas yog tias muaj cov suab nrov txawv txav lossis kub nce.
Lub hydraulic rammer yuav tsum yog perpendicular mus rau qhov chaw ua hauj lwm; tsis txhob tilting nws ntau tshaj 5 degrees.
