Yog hais tias nyob rau hauv lub execrable qhov teeb meem los yog lub system khiav tsis tu ncua nyob rau hauv 24 teev los yog khiav nyob rau hauv plua plav thiab aquosity, lub ncua ncua sij hawm yog ib nrab ntawm daim ntawv 5, kuj deploy ib daim ntaub thaiv npog rau cov bearings.
Infuse lub lubrication maj mam thaum lub kiv cua khiav qis qis lossis jigger nrog tes.
Qhov ntau ntawm append lubrication yog ib feem peb mus rau ib nrab ntawm cov kabmob lossis cov kabmob hauv tsev cubage. Nimiety yog qhov tsis zoo.
daim ntawv 5 lube ntxiv lub sijhawm rau cov kabmob thiab cov kabmob tsev

qhib lub thawv bearing los pauv cov roj
Txawm li cas los xij, qhib lub hau npog npog los xyuas ib zaug txhua xyoo tsawg kawg. (Nrog bearings
Puas muaj qhov caws pliav thiab tawg hauv cov kabmob?
Puas yog cov kabmob brim khi nrog cov kabmob zoo? Puas yog qhov pub dawb txav ib txwm?
Lube ntxiv ntawm lub thawv bearing raws li cov roj qib kab qhov rais (saib NOTE mark
Nyob rau hauv nruab nrab ntawm ncej thiab bearing tsev, tag nrho cov bolts thiab gaskets yog nruj.
Infuse lub lubrication tshiab tom qab ntxuav cov bearings.
khiav kub
Qhov kub txog 40 ℃ ~ 70 ℃ ntawm cov kabmob nto yog ntuj, txwv tsis pub, thaum qhov kub siab tshaj 70 ℃, yuav tsum kuaj xyuas lub sijhawm.
Kev tu thiab xyuas ntawm cov ncej txuas
Tswj lub viav vias windage hauv kev thov nruj me ntsis
Hloov tus pin hnav hauv lub sijhawm.
Kev tu thiab xyuas ntawm lub pulley l thiab V-siv
V- siv
Qhov yuam kev yuav tsum nyob rau hauv qhov tso cai khi thaum lub log muaj qee qhov qhib.
Kev ua yuam kev loj loj cuam tshuam rau kev nkees, libration thiab lub neej ntuj tsim.
Loosen cov bolts nyob rau hauv lub hauv paus ntawm lub cev muaj zog, nruab cov hlua khi tom qab koj tau txais qhov chaw nqaim, yog tias koj muab khoom plig rau cov siv rau hauv cov qhov, cov hlua yuav tawg.
Txhawm rau txo lub neej hauv ntuj thaum cov hlua khi tau stained nrog roj lossis hmoov av, tshwj xeeb yog roj.
Ob lub axes yuav tsum sib npaug, txwv tsis pub, hnav yuav poob qis.
Thov kho qhov tsis sib xws tsawg dua 1/3 °. (Saib daim duab 17)
