Siv lub simulated load (feem ntau yog 125% ntawm qhov ntsuas ua haujlwm load) rau lub tshuab nqa siv calibrated load hlwb lossis ntsuas qhov hnyav.
Ntsuas deflections ntawm lub ntsiab truss thiab muab piv nrog rau qhov tseem ceeb theoretical.
Tswj System Test:
Txheeb xyuas tag nrho cov haujlwm ntawm tus neeg teb xov tooj lub cabin.
Kev ntsuas kev cuam tshuam thiab kev nyab xeeb raws tu qauv (xws li, gantry tsis tuaj yeem txav mus yog tias tsis muaj kev txhawb nqa).
Theem 8: Kev kho deg thiab pleev xim
Kev npaj nto:Tom qab FAT, tag nrho cov qauv yog ntxuav los ntawm xeb, zeb nplai, thiab cov kab mob uas siv cov abrasive blasting (piv txwv li, txhaj tshuaj blasting) mus rau cov qauv teev tseg (xws li Sa 2.5).
Kev kos duab:Ib txheej txheej xim txheej ntau ({0}} primer, intermediate coat, topcoat) yog siv raws li cov kev qhia tshwj xeeb, kom ntseeg tau tias cov zaj duab xis qhuav txaus (DFT).
Theem 9: Dismantling, Marking, thiab ntim
Systematic Dismantling:Lub BLM yog ua tib zoo dismantled nyob rau hauv qhov kev txiav txim rov qab ntawm qhov chaw erection. Qhov sib lawv liag yog npaj los txo qhov chaw rov ua dua lub sijhawm.
Component Marking:Txhua feem raug cim nrog tus lej cim cim sib raug rau kev teeb tsa dav dav thiab erection kos duab.
Ntim:
Hydraulic Cheebtsam thiab hluav taws xob vaj huam sib luag yog kaw los ntawm ya raws thiab hmoov av.
Machined nto thiab threads yog greased thiab tiv thaiv.
Cov tswv cuab ntawm cov qauv tau ntim thiab ruaj ntseg rau hiav txwv- tsim nyog / txoj kev- tsim nyog thauj.
Theem 10: Cov ntaub ntawv thiab xa tawm
Cov ntaub ntawv zaum kawg:Ib daim ntawv ua tiav tau npaj, suav nrog:
Raws li - ua cov duab kos
Vuam daim ntawv pov thawj
Cov ntaub ntawv pov thawj
Hydraulic Circuit Diagrams
Hluav taws xob schematics thiab PLC cov kev pab cuam
FAT Report
Phau Ntawv Qhia Kev Ua Haujlwm thiab Kev Kho
Kev xa:Cov khoom ntim tau ntim rau hauv cov tsheb thauj khoom lossis cov thawv thauj khoom thiab xa mus rau qhov project site.
4.0 Kev Tswj Xyuas Zoo thiab Kev Nyab Xeeb
Kev Tswj Xyuas Zoo:Kev tshuaj ntsuam xyuas thiab kuaj cov phiaj xwm (ITP) yuav ua raws txhua theem. Txhua qhov kev tshuaj xyuas yuav raug sau tseg.
Kev nyab xeeb:Txhua qhov kev tsim khoom thiab kev sib dhos yuav ua raws li cov txheej txheem kev nyab xeeb ntawm lub rooj cob qhia, suav nrog kev tso cai rau kev ua haujlwm kub, siv PPE, thiab LOTO (Lockout-Tagout) cov txheej txheem thaum kuaj hluav taws xob thiab hydraulic.
5.0 Cov ntsiab lus
Cov txheej txheem no ua kom ntseeg tau tias Counterweight Choj Launching Tshuab yog tsim los rau cov qauv siab tshaj plaws ntawm kev ua tau zoo, kev nyab xeeb, thiab kev ua tau zoo, muab kev txhim khu kev qha thiab kev daws teeb meem rau kev tsim kho choj.
Rhiav saib
Lub tuam txhab tau teeb tsa cov cuab yeej ntse tswj kev tswj hwm lub platform, thiab tau teeb tsa 310 teeb (teev) ntawm kev tuav thiab vuam robots. Tom qab ua tiav ntawm txoj kev npaj, yuav muaj ntau tshaj 500 teeb (sets), thiab cov khoom siv sib txuas sib txuas yuav ncav cuag 95% . 32 cov kab vuam tau muab tso rau hauv kev siv, 50 tau npaj los nruab, thiab automation tus nqi ntawm tag nrho cov khoom kab tau mus txog 85%.
