Vuam underwater
Mar 13, 2016

Vuam underwater tau muab faib ua yam tseem ceeb uas yuav tau siv ntau xyoo: "ntub" vuam, uas yog ua li cas nyob hauv cov dej qhib; thiab "hyperbaric" vuam uas yog tog twg los yam "qhuav" hauv tus qhia tshwj xeeb uas ua lub tsev zoo siab enclosure, los yog qhib dej.
Vuam underwater yog ib tug pheej hmoo lawm xwb tab sis tsim nyog vuam. Muaj ntau ntau cov ships cov lug yuav underwater los ua ke los kho, xws li roj offshore rigs thiab cov tankers.

Vuam, yog koj cias kom dhos los yog kho cov co, thiab yog tus cawm ib yam li grouted los yog clamped work unsatisfactory nyob rau hauv ntau zaus.

Ntub vuam underwater

Nyob rau ntawm andquot; wetandquot; vuam underwater, MMA, los sis kev tuav arc vuam yog nug heev tshaj. Qhov no nws yog ib tug variation ntawm shielded hlau arc vuam, uas employs ib waterproof electrode. Rau lwm hom dab siv yog vuam txhuam thiab vuam arc flux-cored. Ob txoj kev no, nyob hauv lub hwj huam mov uas koomtxoos cov welding siv txuas nrog ntawm ib pawg cables thiab hoses.

Lub ntub vuam txoj kev no xwb mas yuav tsis haum cov steels, los yog kom muaj sib npaug, tshwj xeeb tshaj yog nyob ntau dua depths vim yog txoj kev uas yuav tshwm sim los hydrogen cracking.

Yav tom ntej, yuav muaj xav paub zog qhov chaw thiab revised electrode coatings thiaj li weld dua cov steels ntawm ntau dua depths.
Hyperbaric los sis qhuav underwater vuam

Kev siv hyperbaric los qhuav vuam yog kev vuam nyob siab siab ruaj, feem ntau underwater. Thaum hyperbaric vuam yuav tiv ntub dej hauv tus dej qhib, itand #39; s feem ntau ntau yam hauv tus qhia tshwj xeeb uas constructed hyperbaric chamber uas yog ib cheeb tsam uas qhuav. Hom vuam siv ua tib hom ua hauj lwm los ua ke thiab kho thaum ntub dej vuam, namely underwater pipelines, roj offshore rigs, barges thiab ships ntawm qhov ntau thiab tsawg tag nrho.

Hauv hyperbaric vuam, diver/kws cam hlau ua haujlwm tawm sab nraum lub chamber. Cov MMA electrodes tshwj xeeb yog positioned ua ntej los ntawm ib qhov chaw nres nkoj saj zawg zog, thiab tus kws cam hlau manipulates nws thaum nws tig los rau ntawm qhov rais hauv lub enclosure. Ib lub lag newer yog pob tshab tshab plaws Certificate uas koos thaj tsam weld, thiab dej yog evacuated uas siv roj hauv.

Thaum zoo welds yog tsim nyog, qhuav hyperbaric vuam no feem ntau cov kev xaiv. Ntau tswj tus mob puas tau nyob rau hauv ib cov enclosure uas qhuav, xws li cov ntaub ntawv rau ntawm uantej thiab tswg weld cua kub. Tswj tau kawm los tau ib txoj kev welding paub npaum li cas thiab ntau zoo welds mas yuav ntub dej welds tus tib yam.

Qhuav hyperbaric vuam xws li siv nyob rau hauv depths muaj tshaj 400 meters, tiam sis yog koj hom kev kawm tshwj xeeb yog tsim ntuj ib hnub ntawd cia vuam mus 2000 ' meter ' los yog ntau tshaj.
