I. Cov xwm txheej rau kev ua haujlwm vuam
1.Operating neeg ua haujlwm
Muaj ob hom vuam cov neeg ua haujlwm: cov ua haujlwm thiab cov neeg ua haujlwm saib xyuas. Tus qub yuav tsum tau txais kev cob qhia txuj ci kev tshaj lij thiab tom kawg yuav tsum tau twv kev tshuaj xyuas steel thiab tau txais daim ntawv pov thawj cov kws tshaj lij ua ntej ua haujlwm. Cov khoom siv tiv thaiv kev nyab xeeb yuav tsum tau npaj thaum tsim kho thaum muaj kev nyab xeeb ntawm cov neeg ua haujlwm tsim nyog.
2. Pupperating cov cuab yeej
Tom qab cov neeg ua haujlwm tau npaj tiav lawm, lawv xav tau kev pab ntawm cov khoom siv. Qhov no suav nrog kev kos duab, grinders, nqa khoom, tsa cov khoom siv tiv thaiv cov neeg sawv cev, tiaj tus hau, weld gauges, thiab lwm yam.
Ii. Cov kauj ruam ntawm Vuam Kev Ua Haujlwm
Npaj ua ntej
(1) Nkag siab txog cov kev cai ntawm cov duab kos thiab xyuas kom meej qhov zoo ntawm cov cuab yeej.
(2) Yuav rov kuaj dua seb cov txheej txheem sib sau ua ke ntawm cov duab kos lossis cov khoom siv vuam ua kom tau raws li cov qauv ntawm cov duab kos thiab cov txheej txheem txheej txheem.
(3) Xyuas seb cov cuab yeej siv, cuab yeej thiab cov khoom siv fais fab uas yuav tsum tau ua rau kev ua haujlwm tiav.
(4) Mob siab rau ib puag ncig ntawm qhov chaw vuam:
① Cov chaw ua haujlwm kub heev: Thaum ib puag ncig ua haujlwm kub yog}}}}}}}}}}}}}}}}}}}}}}}}}} Cov lus qhia rau saum toj no rau siab tshaj 20 degree ua ntej kev tsim kho. Thaum qhov kub yog qis dua -10 degree, vuam kev ua haujlwm tsis tuaj yeem pom zoo. Kev tsim kho tsuas yog nqa tawm nruj me ntsis raws li kev tsim kho tom qab tsim cov phiaj xwm tshwj xeeb uas tuaj yeem ua kom cov vuam zoo.
② Cov av noo noo yuav tsum muaj ntau dua 90%.
Kev Siv Txheej Txheem
(1) Siv nqa cov khoom nqa los nqa cov khoom sib txuas nrog cov ntsiab lus rack thiab ua kom cov vuam txuas rau hauv cov chaw vuam kom ntau li ntau tau. Rau cov haujlwm nrog ob peb wedds, kab rov tav vuam thiab ntsug vuam siv tau rau kev sib txuas.
(2) Xyuas cov roj stains, xeb, noo noo thiab lwm yam sundries tsis pub dhau 20 hli ntawm cov khoom siv vuam vuam.
(3) Xaiv Vuam cov ntaub ntawv raws li cov txheej txheem vuam uas yuav tsum tau ua thiab kho cov kab hlau ua haujlwm.
(4) ua ntej vuam, nqa tawm cov khoom ua ntej raws li cov khoom siv welded thiab huab cua sov.
(5) Tus qauv loj welds nrog lub thickness ntau dua 40mm thiab cov ntaub ntawv ntawm Q235 thiab siab dua.
(6) Thaum ib puag ncig vuam kub yog qis dua 0 degree yuav tsum tau muab rhaub kom muaj ntau dua {degree, uas loj dua lossis sib npaug rau ob zaug. Lub thickness ntawm cov steel phaj tsis tsawg tshaj 100 hli. Vuam vuam tuaj yeem nqa tawm tom qab cov kauj ruam saum toj no; Thaum qhov tsawg kawg ntawm preheating kub ntawm lub hauv paus hlau yog siab tshaj 20 degree, ib tug siab dua preheating kub yuav tsum tau siv rau preheating.
(7) Thaum vuam cov xwm fab xwm fab yeeb nkab cov khoom sib xyaw rau cov diaphragm, cov vuam sib txuas yuav tsum yog kev tswj hwm nruj. VUAM Seem ntawm ARC hloov chaw vuam yuav tsum tau txuas ntxiv rau qee qhov kev ncua deb rau ob sab. Thaum vuam cov pob qij txha, ntsug thiab kab rov tav vuam kuj tseem siv tau rau cov pob qij txha.
(8) Kev ua raws li cov kev cai vuam ntawm cov txheej txheem ntawm kev siv vuam thiab tswj qhov kub ntawm kev hla kev ntxhov siab thiab deformation. Kev ntsuas xws li "C" clamps tuaj yeem siv rau cov kev sib dhos tag nrho vuam deformation. Thaum lub sij hawm vuam txheej txheem, nws yog ib qho tsim nyog los txuas ntxiv saib cov kab kev vuam thiab weld zoo thiab ua kom haum raws li qhov txawv txav. Lub thickness ntawm txhua weld yuav tsum tsis txhob muaj ntau dua 5 hli, thiab qhov dav ntawm txhua lub weld yuav tsum tsis txhob muaj ntau tshaj 15 hli. Thaum ib tus neeg sib tw yuav tsis tuaj yeem ua tau raws li cov kev xav tau ntawm Weld loj, Multi-Ple welding yog qhov yuav tsum tau ua, thiab cov interlayer kub yuav tsum tau tswj hwm nruj me ntsis. Tus interlayer kub yuav tsum tsis txhob qis dua qhov tsawg kawg nkaus preheating kub lossis siab dua 230 degree.
(9) Tom qab qhov chaw vuam tau ua tiav, siv lub ntsej muag tiaj tus, siv lub ntsej muag tiaj tus thiab txoj kev sib tsoo los ua cov txheej txheem burrs, vuam slag thiab welds welds nyob rau saum npoo ntawm cov steel ntu. Yog tias muaj qee yam tsis xws luag, lawv yuav tsum tau kho. Tom qab cov Welds tau ua tiav kiag li txias thiab ua tau kev sim ua tsis zoo, tsis yog kev sim ua kom muaj kev sib tw ntawm cov ntaub ntawv hauv kev nkag mus. Yog tias muaj cov kev tsis xws luag, cov pa roj arc gouging lossis ib qho grinder tuaj yeem siv los tshem tawm cov tsis xws luag thiab nqa tawm kev hloov vuam.
