Phau Ntawv Qhia rau Rooj Sib Tham, Txhim Kho, Siv thiab txij nkawm ntawm Crane Hooks
Crane hooks yog cov tseem ceeb hauv kev nqa khoom. Lawv sib dhos, siv thiab kho ncaj qha cuam tshuam rau kev ua haujlwm kom nyab xeeb thiab ua haujlwm. Kab lus no yuav muab faib ua peb ntu, kev kawm txog cov txheej txheem txheem ntawm CRANE Hooks los pab cov neeg siv kev nyab xeeb thiab kev ua haujlwm zoo.
Ua ntej: Tus qauv sib dhos thiab kev teeb tsa ntawm Crane Hooks
Cov rooj sib dhos ntawm Crane Hooks yuav tsum nruj ua raws li ISO 4309, ASME B30.10) kom ntseeg tau tias lawv cov khoom siv thauj khoom thiab kev nyab xeeb. Cov ntsiab lus tseem ceeb hauv qab no yuav tsum tau sau tseg thaum lub sijhawm teeb tsa:
1. Kev tshuaj xyuas ua ntej ua ntej uas tus nuv tsis muaj cov kab nrib pleb, deformation lossis kev coj tsis zoo, thiab cov khoom tsis zoo, thiab cov khoom tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov khoom tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis huv, thiab cov tshuaj tiv thaiv tsis huv, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov tshuaj tiv thaiv tsis zoo, thiab cov khoom siv tsis zoo, thiab cov tshuaj tiv thaiv tsis huv, thiab cov tshuaj tiv thaiv hnyav
2. Qhov kev sib txuas yog: Siv lub zog ua kom nruj kom nruj cov bolts kom ntseeg tau tias tus nuv ntais ntawv swb rau eccentric chaw thau khoom eccentric.
3. Cov kev sim ntsuas: Tom qab kev teeb tsa, ua ib 1.25 zaug ntsuas ntsuas thauj khoom thiab saib rau 10 feeb ua ntej tso nws siv.
4. Kev ntsuas thiab Center
Cov kev sib dhos ua ke yuav ua tau zoo zam crane nrog kev sib tw ua rau muaj kev cuam tshuam thiab txhim kho cov cuab yeej kev ntseeg tau.
Thib ob: Cov ntsiab lus tseem ceeb rau kev siv crane hooks muaj kev nyab xeeb
Hauv kev ua haujlwm txhua hnub, kev siv tau tuaj yeem loj dua lub neej ntawm crane nuv thiab txo kev pheej hmoo ntawm cov xwm txheej. Saib xyuas tshwj xeeb yuav tsum tau them rau:
Overloading tau nruj me ntsis: tag nrho cov nra (suav nrog qhov hnyav
✔ Zam tag nrho rub: Tswj ntsug kom tiv thaiv kev nro tom qab los ntawm kev ua txhaum lossis tawg ntawm tus nuv.
✔ Kev Soj ntsuam kev tsis tu ncua: Kos rau cov khaub ncaws nuv ua ntej thiab tom qab txhua qhov siv (deformation ntawm ntau dua 10% xav tau hloov), kev sib hloov hloov pauv thiab cov xwm txheej ntawm kev nyab xeeb.
✔ Ib puag ncig kev hloov kho: tom qab ua haujlwm hauv qhov kub lossis kub thiab huab cua qhov chaw yuav tsum tau ntxuav thiab lubricated hauv lub sijhawm.
Raws li kev txheeb cais, kwv yees li 70% ntawm cov kev huam yuaj ntawm nuv tau tshwm sim los ntawm kev ua haujlwm tsis raug cai lossis tsis muaj kev soj ntsuam txhua hnub, yog li kev ntsuas nruj nrog kev siv cov kev qhia tshwj xeeb.
Peb: Kev Tshawb Fawb Kev Tshawb Fawb rau Crane Hooks
Txhawm rau kom muaj kev ua haujlwm ntev ruaj khov ntawm crane nuv, nws raug pom zoo kom siv txoj kev npaj kho hauv qab no:
- Kev Tu Niaj Hnub: Tshem tawm cov pob hluav taws thiab kuaj lubrication.
- Kev tshuaj xyuas txhua hli txhua hli: ua kev tshuaj ntsuam sib nqus (MPI sib nqus
- Kev Kho Dua Txhua Xyoo Overhaul: Disassemble thiab tshawb xyuas cov kabmob thiab cov ntsaws ruaj ruaj, thiab hloov cov khoom hnav yog tias tsim nyog.
- SCRAP Txuj Ci: Thaum tus nuv tau tawg, loj deformed, lossis lub book caj pas qhib ntxiv los ntawm 15%, nws yuav tsum tau hloov tam sim ntawd.
