Kev tu thiab kho cov cranes yog qhov tseem ceeb rau kev nyab xeeb thiab kev pabcuam lub neej ntawm cov khoom siv. Cov hauv qab no yog cov kev paub thiab cov lus qhia txog kev tu thiab kho crane:
1. Kev tshuaj xyuas txhua hnub
Hydraulic system: Xyuas seb cov roj hydraulic puas txaus, xyuas kom meej tias cov roj huv huv, thiab saib seb puas muaj cov pa tawm.
Hlau hlua thiab nuv: xyuas seb cov hlua hlau puas hnav los yog tawg, seb tus nuv puas tawg los yog deformed, thiab seb qhov kev sib txuas ntawm cov hlua khi puas ruaj khov.
Lubricated qhov chaw: Txhua qhov txav thiab tig, xws li rubeys, bearings, chains, thiab lwm yam, yuav tsum tau lubricated tsis tu ncua kom tsis txhob hnav thiab jamming.
Lub tshuab hluav taws xob: xyuas kom meej tias cov hluav taws xob hluav taws xob thiab lub tshuab hluav taws xob tsis muaj kev laus, luv luv, kev sib cuag tsis zoo thiab lwm yam teeb meem, thiab xyuas seb lub txee hluav taws xob puas muaj cov tsos mob ntawm overheating.
2. Kev tu ncua sij hawm
Lubrication txij nkawm: Raws li cov cuab yeej siv phau ntawv, tsis tu ncua hloov thiab ntxiv cov roj lubricating kom ntseeg tau tias kev ua haujlwm zoo ntawm cov iav, bearings thiab lwm yam khoom.
Kev hloov roj hydraulic: Cov roj hauv hydraulic feem ntau yog hloov txhua 6-12 lub hlis los tiv thaiv impurities los ntawm precipitating thiab cuam tshuam rau kev ua haujlwm ntawm lub cev.
Kev tshuaj xyuas lub tshuab nres: tsis tu ncua xyuas thiab hloov cov pawm nres kom ntseeg tau tias lub nres nres tuaj yeem ua haujlwm ib txwm muaj thaum muaj xwm txheej ceev.
Kev tshuaj xyuas cov qauv hlau: xyuas seb cov qauv tseem ceeb ntawm lub crane (xws li lub boom thiab lub ntsiab nqaj) puas muaj cov kab nrib pleb, deformation lossis corrosion, thiab kho lossis hloov yog tias tsim nyog.
3. Kev saib xyuas zoo
Hlau hlua thiab nuv: Yog tias cov hlua hlau pom tias hnav, corroded, los yog tawg, nws yuav tsum tau hloov tam sim ntawd. Thaum tus nuv yog deformed, tawg, los yog hnav tshaj qhov txwv, nws yuav tsum tau hloov raws sij hawm.
Kev saib xyuas cov khoom siv hluav taws xob: Yog tias cov khoom siv hluav taws xob xws li cov motors, relays, thiab controllers ua tsis tiav, cov kws tshaj lij hluav taws xob yuav tsum tau hloov thiab kho lawv kom ntseeg tau tias txhua yam khoom siv hluav taws xob ua haujlwm zoo.
Hydraulic system tu: Yog hais tias lub hoses, li qub, twj thiab lwm yam khoom ntawm hydraulic system puas los yog to, lawv yuav tsum tau hloov thiab kaw los ntawm cov tub txawg kom tsis txhob poob siab system.
Rotating thiab kis tau tus mob qhov chaw: Yog hais tias lub rotating bearings los yog kis tau tus mob gears tau pom tias yog hnyav hnyav, lawv yuav tsum tau hloov tam sim ntawd kom tsis txhob cuam tshuam cov kev khiav hauj lwm raug thiab stability ntawm cov khoom.
4. Kev tshuaj xyuas tsis tu ncua thiab calibration
Load test: Ua cov kev ntsuam xyuas tsis tu ncua txhawm rau txheeb xyuas seb lub peev xwm ntawm lub crane puas ua tau raws li cov qauv thiab xyuas kom muaj kev nyab xeeb.
Kev tshuaj xyuas cov cuab yeej kev nyab xeeb: suav nrog kev txwv kev hloov pauv, cov khoom siv tiv thaiv overload, khawm nres thaum muaj xwm ceev, thiab lwm yam, txhua yam yuav tsum tau kuaj xyuas tsis tu ncua thiab ntsuas kom ntseeg tau tias cov cuab yeej no tuaj yeem ua haujlwm hauv cov xwm txheej txaus ntshai.
5. Kev saib xyuas raws caij nyoog
Kev saib xyuas lub caij ntuj no: Thaum lub caij txias, cov roj hydraulic thiab cov roj lubricating tuaj yeem ua tuab dua vim qhov kub thiab txias. Cov roj lubricating uas kub qis yuav tsum tau siv, thiab cov khoom siv cua sov ntawm cov khoom siv yuav tsum tau kuaj xyuas seb nws puas zoo li qub.
Kev saib xyuas lub caij ntuj sov: Nyob rau lub caij kub kub, kev saib xyuas tshwj xeeb yuav tsum tau them rau cov cua kub dissipation ntawm hydraulic thiab hluav taws xob systems kom tsis txhob muaj kev puas tsuaj rau cov khoom siv vim overheating.
6. Cov ntaubntawv povthawj siv thiab taug qab
Cov ntaub ntawv khaws cia: Cov ntaub ntawv ntxaws ntxaws yuav tsum tau sau tseg rau txhua qhov kev saib xyuas thiab kho, suav nrog cov khoom hloov pauv, hom roj lubricating siv, kev tshuaj ntsuam xyuas, thiab lwm yam, rau kev taug qab yav tom ntej.
Cov ntaub ntawv tsis raug: Qhov laj thawj ntawm qhov ua txhaum, cov txheej txheem tuav thiab cov khoom seem siv yuav tsum tau sau tseg rau txhua qhov kev kho, thiab cov ntaub ntawv khaws cia keeb kwm ntawm cov cuab yeej yuav tsum tau tsim kom nkag siab zoo dua cov khoom siv.
7. Ua raws li cov neeg tsim khoom phau ntawv
Txhua tus qauv crane muaj qhov kev saib xyuas sib txawv. Nco ntsoov ua raws li cov lus qhia thiab kev saib xyuas phau ntawv qhia los ntawm cov chaw tsim khoom thiab ua haujlwm raws li kev pom zoo thiab kev saib xyuas lub voj voog.
Los ntawm kev tu thiab kev kho thiab kev ua haujlwm tsis tu ncua, kev pabcuam lub neej ntawm crane tuaj yeem txuas ntxiv tau zoo, kev ua haujlwm tau zoo tuaj yeem txhim kho, thiab kev nyab xeeb ntawm kev ua haujlwm tuaj yeem ua kom ntseeg tau.
