Txhawm rau kom muaj kev nyab xeeb kev ua haujlwm, kev ua haujlwm zoo tshaj plaws, thiab lub neej ntev ntawm cov khoom sivchaw taws teeb tswj grab, cov neeg ua haujlwm yuav tsum ua raws li cov txheej txheem hauv qab no thiab kev tiv thaiv kev saib xyuas.
1. Kev teeb tsa thawj zaug thiab ua ntej-Kev soj ntsuam kev ua haujlwm
Kev Nyab Xeeb Kev Nyab Xeeb:Txhua tus neeg ua haujlwm yuav tsum ua raws li cov cai tiv thaiv kev sib tsoo thiab cov txheej txheem kev nyab xeeb rau kev nqa khoom.
Kev tshuaj xyuas thawj zaug:
Siv lub crane los nqa lubtej thaj chaw deb- tswj tuavthiab xyuas cov roj hydraulic, raws li qhia hauv daim duab qhia.
Hydraulic kua:Yog tias cov dej xau tshwm sim thaum thauj, rov qab tam sim ntawd. Ntawm qhov kub thiab txias, nws raug nquahu kom siv cov tshuaj tiv thaiv - hnav cov roj hydraulic nrog ib qhoISO VLP HLP VG46 viscosity qib.
Visual Check:Tshawb xyuas qhov chaw sab nraud ntawm qhov rub kom ntseeg tau tias tsis muaj kev puas tsuaj lossis cov roj xau.
Mechanical Check:Xyuas kom tseeb tias tag nrho cov bolts thiab cov khoom sib txuas yog nruj nruj.
Kev tshuaj ntsuam xyuas:
Tshawb xyuas lub qhov (socket), kab, thiab cov hlua khi hlua khi ua ntej siv. Xyuas kom lawv ua tau raws li cov kev cai thiab raug nruj kom raug.
Hloov cov khoom puas:Cov Cheebtsam yuav tsum tau hloov tam sim ntawd yog tias pom muaj kev puas tsuaj, suav nrog tab sis tsis txwv rau cov shackles deformed, tawg qhov sib tsoo, lossis puas, tawg, lossis hnav cov hlua khi hlua khi ntau dhau.
2. Kev sim ua haujlwm
Tsis muaj-Load Test:Ua qhov khoob -Load test kom paub meej tias txhua qhov kev sib hloov ua haujlwm tau yooj yim. Xyuas kom tseeb tias covchaw taws teeb tswj grabqhib thiab kaw kom raug thiab smoothly yam tsis muaj hesitation.
3. Cov lus qhia ua haujlwm
Kev Tiv Thaiv Kev Tiv Thaiv:Txhawm rau tiv thaiv kev puas tsuaj, tsis txhob cuam tshuam cov khoom siv, nqa cov khoom siv, lossis lub nkoj sab ntawm kev kub ceev.
Balance Ncej:Xyuas kom tus ncej sib npaug ntawm lub beam sab sauv viav vias dawb. Cov hlua khi hlua yuav tsum muaj peev xwm ua viav vias ywj pheej thiab tuav txoj haujlwm kab rov tav thaum ua haujlwm.
Qhov chaw:
Thaum positioning lubchaw taws teeb tswj tuav thoobhla cov khoom, ua kom nws ntsug li sai tau kom tso cai rau nruab nrab nqaj kom qis qis.
Tsis txhob tilting ntau dhau. Lub kaum sab xis loj ua rau lub zog tseem ceeb ntawm lub tog raj kheej piston pas nrig, uas tuaj yeem cuam tshuam nws cov hlab ntsha rov qab thiab ua rau muaj kev puas tsuaj.
4. Lubrication thiab tu
Lubrication Points:Tsis tu ncua lubricate tag nrho cov rotating ncej pins, hlua qhia pab kiag li lawm, thiab cov menyuam bearings raws li nram no:
Ua ntej siv txhua qhov:Lubricate ua ntej lub rub pib ua haujlwm.
Thaum ua haujlwm tas mus li:Lubricate tsawg kawg ib zaug txhua 24 teev ntawm kev ua haujlwm tas mus li.
Tom qab txhua qhov kev siv:Lubricate tom qab txhua lub sijhawm ua haujlwm.
Kev kaw thiab cia:
Ntxuav:Thaum cov chaw taws teeb tswj tuav raug tshem tawm ntawm kev pabcuam, ntxuav nws kom huv si kom tshem tawm cov khoom siv hauv nruab nrab ntawm lub nqaj lossis nyob hauv qhov khoob ntawm qhov sib hloov.
Txoj hauj lwm:Lub khob yuav tsum tau muab tso rau hauv ib qhokaw txoj hauj lwm.
Ntev - Lub Sij Hawm Cia:Yog tiaschaw taws teeb tswj grabyuav tsis siv rau ib lub sij hawm ntev, siv roj txaus los yog lubricating roj rau tag nrho cov ntsiab lus pob khawm kom tiv thaiv corrosion thiab seizing.
