Dab tsi yog qhov sib txawv ntawm ntub thiab qhuav underwater vuam?

Underwater vuam, raws li ib tug tseem ceeb thev naus laus zis engineering, offshore roj tsis raug, thiab muab faib ua ob pawg vuam: ntub dej underwater vuam thiab qhuav underwater vuam. Ob lub thev naus laus zis sib txawv ntau hauv kev ua haujlwm ib puag ncig, khoom siv, kev ua haujlwm vuam ua si, thiab kev siv cov xwm txheej. Kev nkag siab meej txog lawv qhov sib txawv yog qhov tseem ceeb rau kev xaiv cov qauv vuam tsim nyog hauv cov haujlwm ua haujlwm.
Tub ntxhais sib txawv hauv cov chaw ua haujlwm
Ntub Dej underwater vuam
Nyob rau hauv ntub dej hauv av, lub welder thiab chaw vuam yog kiag li raug dej ib puag ncig thaum ib puag ncig vuam ib puag ncig. Tsis muaj ib lub twj siv kev cais ntawm kev siv kev sib cais ntawm kev ua haujlwm sib cais thiab cov dej nyob ib puag ncig, thiab cov vuam arc ncaj qha hlawv hauv dej. Cov dej kub, siab, thiab txaus tus nqi hauv thaj chaw ua haujlwm yuav cuam tshuam ncaj qha rau cov txheej txheem vuam. Piv txwv li, hauv thaj chaw hiav txwv tsis muaj dej hiav txwv
Qhuav underwater vuam 
Qhuav underwater vuam tsim ib qhuav lossis semi -} qhov chaw ua haujlwm qhuav rau lub vuam. Ib qho chaw kaw (xws li lub nkoj siab lossis cov chaw nyob) tau teeb tsa ib ncig ntawm cov av vuam (xws li sim ua av {{2} Zoo li ib puag ncig vuam. Cov ntaub thaiv hluav taws tuaj yeem ua haujlwm sab hauv lub chamber lossis tswj cov vuam hlau remotely. Lub siab nyob rau hauv lub chamber feem ntau yog sib npaug nrog sab nraud dej siab kom zam dhau kev puas tsuaj rau lub chamber. Piv txwv li, hauv kev sib sib zog nqus - pas dej vuam ntawm ib qho tob ntawm lub chamber, lub siab sab hauv siab ntawm lub chamber yuav raug muab kho kom phim rau sab nraud dej siab.
Qhov sib txawv hauv cov khoom siv vuam thiab cov khoom siv
Ntub Dej underwater vuam
• Vuam lub zog hluav taws xob: Tshwj xeeb DC lub zog hluav taws xob nrog siab ruaj khov tam sim no yuav tsum tau tiv thaiv cov dej cuam tshuam ntawm arc. Cov zis tam sim no feem ntau yog 300-600, thiab lub voltage yog 20-40v, uas tuaj yeem tswj cov arc prolusion hauv dej.
• Cov khoom lag luam: Cov hluav taws xob dej yog siv. Cov txheej ntawm cov hluav taws xob no muaj cov khoom xyaw xws li flux thiab roj - generating tus neeg sawv cev. Thaum rhuab, cov nkev - generating cov pa roj (xws li cov pa roj carbon dioxide (xws li hydrogen) los ua cov yeeb yaj kiab roj ib ncig ntawm cov dej. Piv txwv li, E7018 Underwater hluav taws xob muaj cov txheej tuab uas tuaj yeem ua kom cov pas dej txias qeeb ntawm Molten.
• Welder cov khoom siv: cov kws kho tsiaj hnav ib lub kaus mom dhia dej, cov kaus mom ntoo thiab cov dej tsis muaj dej. Lub teeb vuam yog tsim los ua waterproof thiab anti -} Hluav Taws Xob Hluav Taws Xob los tiv thaiv txheej txheem tam sim no.
Qhuav underwater vuam
• Kaw cov chaw chamber: Qhov no yog cov cuab yeej tseem ceeb, suav nrog lub siab {}}}}}}}}}}}} pa twj, roj tswj li qub, thiab siab sensors. Lub chamber feem ntau yog ua los ntawm high- lub zog steel lossis titanium alloy los tiv thaiv dej siab. Piv txwv li, cov chav vuam qhuav los siv rau hauv cov pa roj teeb hluav taws xob tuaj yeem ua tiav qhov siab tiv thaiv txog li 50 - hiav txwv ib puag ncig hauv qab 500 meters.
• Cov khoom siv vuam: Cov hau kev vuam hlau zoo ib yam li cov av, xws li cov thaiv hlau arc vuam (smaw) thiab roj hlau arc vuam (GMAW). Lub zog vuam qhov chaw thiab teeb pom kev pab dej tshwj xeeb, tab sis lawv yuav tsum tau tshaj tawm cov kev ntsuas siab hauv lub chav.
• AUXILIARIA SYSTEMS: INVERSE Cov Tshuab (tswj cov chaw qhuav huv), kom tiv thaiv kev ua haujlwm (los pab cov chaw ua haujlwm tej thaj chaw deb) muaj nyob nrog.
Qhov sib txawv ntawm kev ua yeeb yam kev ua tau zoo thiab ua tau zoo

• Arc Stability: ARC tau yooj yim los cuam tshuam los ntawm dej ntws thiab dej vapor, ua rau muaj kev cuam tshuam tsis ruaj khov. Tus nqi ua kom txias ntawm lub pas dej Molten yog qhov ceev heev (txog 10-100 lub sij hawm uas yuav ua rau cov av hauv av weld.
• Weld tshuab hluav taws xob: lub zog ntawm lub weld feem ntau yog 70% -80% ntawm cov av av vuam, thiab cov kev cuam tshuam nyuaj yog qis dua. Piv txwv li, qhov kev cuam tshuam lub zog ntawm Weld hlau hauv cov hlau vuam ntawm cov hlau yog feem ntau 20-30J, uas yog qis dua 40-60J hauv cov av hauv av.
• Ntshiab Dision: Nws yog tus nquag ua rau tsis xws li ib yam li dej caw (tshwm sim los ntawm cov dej pheebsuab (tshwm sim los ntawm kev ua kom huv si Tus nqi tsim nyog ntawm ib qho -} ntev ntev ntev 60% -80%.
Qhuav underwater vuam
• Arc Stability: Lub arc hlawv nyob rau hauv ib qho chaw qhuav lossis inert rade nyob ze ntawm thaj av vuam. Tus nqi cua txias ntawm lub pas dej Molten yog qeeb, uas yog qhov zoo rau kev khiav dim ntawm cov roj thiab ntab ntawm slag.
• Weld tshuab cov khoom siv khoom: Weld lub zog thiab kev nruj heev nyob ze ntawm cov av vuam. Piv txwv li, lub zog tensile ntawm weld hauv cov vuam qhuav ntawm qis {}}} alllo allloy tuaj yeem ncav cuag 35-50j.
• Ntshiab qhov ntsuas: tus nqi tsis tshua muaj tsawg, thiab ib qho - lub sij hawm vuam tus nqi tuaj yeem ncav cuag 90% -95%. Cov khoom tsis xws luag yog feem ntau tshwm sim los ntawm kev teeb tsis raug, xws li overheating lossis nkag tsis txaus.
Qhov sib txawv hauv kev thov cov xwm txheej thiab tus nqi
Ntub Dej underwater vuam
• Daim ntawv thov tau txais: Haum rau ntiav dej (feem ntau tsis pub dhau 50 meters) thiab tsis yog} kev saib xyuas thaum muaj xwm ceev, thiab vuam ntawm cov choj hauv qab. Piv txwv li, thaum ib 20 {{4 4}}}}}} meter 'tob dej
• Tus nqi: Cov peev txheej kev tso peev yog tsawg (feem ntau cov khoom siv roj av thiab hluav taws xob tshwj xeeb), thiab kev tsim kho yog luv. Tus nqi ib lub ntsuas ntawm vuam feem ntau 500-1,000 Asmeskas las, uas yog haum rau cov haujlwm uas muaj peev nyiaj tsawg.
• Cov txiaj ntsig zoo thiab qhov tsis zoo: Qhov zoo yog hloov tau thiab teb sai; Qhov tsis zoo yog qhov ua tsis zoo vuam zoo thiab siab yuav tsum muaj rau cov neeg muaj kev txawj ntse (lawv yuav tsum tau ua ob qho tib si dhia dej).
Qhuav underwater vuam
• Daim ntawv thov tau txais: Haum rau kev nqus dej (ntau tshaj 50 meters) thiab kev sib txuas ntawm cov hluav taws xob ntawm ntug dej hiav txwv, thiab txij nkawm ntawm cov fais fab kev cog qoob loo, thiab kev txij nkawm ntawm cov fais fab ntoo cog qoob loo. Piv txwv li, cov vuam ntawm 300 {{4 4}} '' meter '{5}}' meter '{
• Tus nqi: Cov khoom lag luam yog loj heev (tus nqi ntawm cov txheej txheem vuam qhuav tuaj yeem ua haujlwm ntau lab nyiaj), thiab kev sim ua haujlwm zoo li Chamber thiab sim ntsuas). Tus nqi rau ib lub ntsuas ntawm vuam yog 5,000-20,000 Asmeskas las, uas tsuas yog siv nyob rau hauv high - tus nqi ntawm cov phiaj xwm.
• Cov txiaj ntsig zoo thiab qhov tsis zoo: Qhov kom zoo dua yog qhov ua tau zoo thiab ruaj khov, uas tuaj yeem ua kom tau raws cov qauv tsim kho nruj; Qhov tsis zoo yog qhov tsis zoo thiab siv sijhawm ntev.
Xaiv cov tswv yim rau kev siv cov ntawv engineering
Cov kws tshaj lij kev lag luam qhia tias kev xaiv ntawm ntub dej thiab qhuav hauv qab vuam yuav tsum yog raws li cov hauv qab no:
• Dej vuam: ntub dej vuam yog nyiam rau cov dej ntiav tsis pub dhau 50 meters, thiab vuam qhuav, thiab cov vuam qhuav kom pom zoo rau dej tob tshaj 50 meters.
• Cov Txheej Txheem Tseem Ceeb: cov cuab yeej tseem ceeb (xws li roj platforms thiab nuclear fais fab cuab yeej) uas xav tau kev ua haujlwm ntev yuav tsum siv vuam qhuav; Tsis - tseem ceeb txheej txheem lossis kev kho ib ntus tuaj yeem siv cov vuam ntub.
• Kev Siv Nyiaj thiab Kev Siv Condition: Wood VUAM Welding yog haum rau cov phiaj xwm nrog kev siv peev nyiaj thiab sai sai; Yog xaiv cov vuam qhuav yog qhov ua tau zoo yog thawj zaug kev txiav txim siab thiab cov peev nyiaj tau txaus.
• Xav tau cov kev xav tau zoo: yog tias tus Weld xav tau withstand siab, corrosion, lossis kev ua kom zoo nkauj (yuav tsum muaj vuam qhuav; Yog tias tsuas yog kev sib txuas ib ntus yog xav tau, cov vuam sib tw tuaj yeem ua kom tau raws li qhov yuav tsum tau ua.
Hauv kev xaus, ntub thiab qhuav underwater warding muaj lawv tus yam ntxwv thiab muaj cov xwm txheej muaj feem xyuam. Nrog rau kev txhim kho cov tub rog ua haujlwm, xws li siv tshuab war Nyob rau hauv yav tom ntej underwater engineering, ob lub thev naus laus zis yuav ua tiav txhua yam los muab kev txhawb nqa kev txhim kho rau kev txhim kho thiab kev saib xyuas hauv qab.
