Cov qauv yuav tsum muaj ntawm All-titanium Vessel

Tag nrho cov thawv titanium txhais tau hais tias cov khoom tseem ceeb, xws li lub plhaub, lub taub hau thiab lub receiver ua los ntawm titanium, qhov thib ob tuaj yeem ua los ntawm cov hlau tsis muaj titanium, piv txwv li, flange thiab nws cov bolts txuas tuaj yeem ua los ntawm cov hlau.
Tag nrho cov titanium thawv plhaub yam tsawg kawg nkaus thickness ntawm 2 hli, feem ntau yog ua kom tau raws li cov txheej txheem vuam nyob rau hauv kev tsim cov thickness yuav tsum tau thiab xyuas kom meej tias cov geometric dimensional tolerances ntawm cov yuav tsum tau ua kom tau raws li qhov kev tsim, tsheb thauj mus los thiab lifting txheej txheem ntawm qhov yuav tsum tau nruj nruj; nrog rau kev txuag titanium, txo cov nqi.
Tsim cov qauv kev xaiv
Raws li titanium ntawm qhov kub siab tshaj los yog sib npaug rau 200 degree, lub zog txhua yam ntawm qhov poob qis, thiab titanium lub modulus ntawm elasticity yog tsawg, yog li ntawd, tag nrho-titanium qauv nyob rau hauv qhov kub thiab txias, siab siab los yog nruab nrab siab thiab loj-scale khoom. daim ntawv thov tsis tsim nyog.
Qhov tso cai kub ntawm tag nrho cov titanium siab lub nkoj yuav tsum tsis pub tshaj 250 degree, thiab hais tias lub siab nyob rau hauv 0.5MPa, qhov kub yog qis dua 150 degree me me thiab nruab nrab lub thawv xaiv ntawm tag nrho cov titanium qauv yog ntau yig. Los ntawm cov nqi peev kev txiav txim siab suav cov thickness ntau dua 13 hli, kev siv cov titanium ntshiab yuav tsis raug nqi.

Cov qauv tsim nyog
Txawm hais tias tag nrho cov titanium ntim hauv cov qauv tsim thiab cov hlau tsis muaj steel zoo sib xws, tab sis vim qee cov khoom tshwj xeeb ntawm titanium nws tus kheej, yog li ntawd, nyob rau hauv kev tsim thiab kev ua thiab kev tsim ntawm nws cov uniqueness, yog li nyob rau hauv cov qauv tsim, yuav tsum tau them nyiaj mloog mus rau. cov ntsiab lus hauv qab no:
1) Hauv kev tsim cov qauv vuam, yuav tsum ua kom qhov vuam tau yooj yim rau kev khiav lag luam hydrogen arc vuam cov cuab yeej, thiab ua kom tag nrho cov nyob rau hauv qhov kub siab (ntau tshaj 400 degree) ntawm qhov sib koom ua ke welded cheeb tsam tuaj yeem tiv thaiv tau zoo.
Titanium, nyob rau hauv nws lub xeev molten, muaj peev xwm ntawm chemically combining nrog yuav luag txhua lub caij, yog li tshwj xeeb kev tiv thaiv yuav tsum tau coj thaum lub sij hawm vuam thiab kub ua. Txhawm rau ua kom muaj kev tiv thaiv zoo, cov duab ntawm cov qauv ntawm cov khoom yuav tsum yooj yim, thiab lub receiver qhib ntawm lub plhaub yuav tsum yog perpendicular mus rau lub axis ntawm lub plhaub kom ntau li ntau tau, kom cov kev tiv thaiv fixture yog ib qho yooj yim mus ua thiab kev tiv thaiv. cov nyhuv zoo dua.
2) nruj me ntsis zam cov vuam qauv ntawm cov hlau, titanium kev sib nrig sib fusion. Raws li cov hlau thiab lwm yam hlau fused rau titanium weld yuav tsim ib qho nyuaj thiab nkig nruab nrab ntawm cov hlau sib txuas, zoo heev txo cov weld plasticity, ntxiv rau kev tawg vuam thiab brazing, titanium thiab hlau tsis tuaj yeem welded.
3) Butt welded pob qij txha blunt ntug clearance yuav tsum tsim nyog. Tag nrho cov titanium siab txog ntsha pob tw welded pob qij txha yuav tsum me dua lub blunt ntug qhov sib txawv ntawm hlau, qhov no yog vim lub siab melting point ntawm titanium, tsis zoo thermal conductivity, tshav kub muaj peev xwm thiab kuj coefficient ntawm me me thiab welded molten pas dej ua ke ntawm hlau fluidity.
4) Titanium thawv tsim yuav tsum xyuas kom meej cov txheej txheem txuas ntxiv thiab kev hloov pauv ntawm cov pob qij txha, sim kom tsis txhob muaj kev ntxhov siab.
5) Kev khoov thiab flanging ntawm titanium qhov chaw yuav tsum tau txais qhov loj dua (piv nrog cov hlau) dabtsi yog khoov vojvoog, thiab thaum nthuav cov yeeb nkab, yuav tsum siv tus nqi me me.
6) Muaj cov ntshiab titanium nyob rau hauv ib co xov xwm nkig rau crevice corrosion, nyob rau hauv lub tsim, ua thiab cov xov xwm kev sib cuag nrog lub thawv, yuav tsum tau sim kom tsis txhob muaj cov tsos ntawm lub crevice thiab stagnant ntws cheeb tsam, nyob rau hauv lub crevice nrog crevice corrosion-resistant titanium alloy. (xws li titanium-palladium alloy) los yog txheej.
7) nyob rau hauv kev tsim, ua thiab conductive corrosive xov xwm nyob rau hauv kev sib cuag nrog lub thawv, xws li pom nyob rau hauv titanium thiab lwm yam hlau sib cuag tuaj yeem ua rau galvanic coupling corrosion, yuav tsum nyob rau hauv cov qauv ntawm kev ntsuas (xws li kev siv ib feem peb. cov khoom siv raws li kev hloov pauv txheej) lossis kev siv anodic tiv thaiv.
8) Hauv kev tsim cov cuab yeej ua rau corrosion, tus nqi ntws ntawm qhov nruab nrab corrosive yuav tsum qis dua qhov tseem ceeb ntawm tus nqi ntws, thiab sim kom tsis txhob muaj kev hloov pauv tam sim ntawd ntawm qhov ntws los yog kev taw qhia ntawm ntws; los yog nyob rau hauv qhov chaw uas muaj corrosion thiab abrasion los teeb baffles tiv thaiv.
① When the medium is corrosive or abrasive and ρv2>740kg/(m-s2) or the medium is not corrosive or abrasive, but ρv2>2355kg / (m-s2) (ρ yog qhov ceev ntawm qhov nruab nrab, kg / m3, v yog linear tshaj tawm ntawm cov khoom ntws, m / s), cov khoom nkag yuav tsum tau teeb tsa nrog baffle.
② Thaum lub corrosive nruab nrab raws li tangential rau hauv cov khoom siv, los yog cov yeeb nkab inlet yog tig rau ntawm phab ntsa, thiab qhov deb ntawm lawv yog tsawg tshaj li 2 npaug ntawm sab kab ntawm cov yeeb nkab, yuav tsum tau teem los tiv thaiv lub phaj.
