Yuav Ua Li Cas Kho Kev Tsim Khoom Tsis Zoo hauv Cov Nkoj Siab?

I. Sib Tsoo Kho – Haum rau me me qhov chaw tsis xws luag

Rau qhov tsis xws luag xws li cov kab nrib pleb, undercut, craters, khawb, lossis me me corrosion, yog tias lawv tsis cuam tshuam rau lub zog ntawm cov qauv thiab cov phab ntsa tuab tom qab sib tsoo raws li qhov yuav tsum tau muaj zog, kev sib tsoo tuaj yeem siv los tshem tawm lawv.

1. Siv lub kaum sab xis grinder lossis ntiv tes grinder txhawm rau txhawm rau qhov chaw tsis zoo. Kev sib tsoo contour yuav tsum muaj kev hloov pauv, nrog lub kaum ntse ntse tswj ntawm 1: 3 lossis siab dua kom tsis txhob tsim cov kaum ntse ntse.

2. Tom qab kev sib tsoo, kev ntsuam xyuas kev nkag siab (PT) lossis kev ntsuas qhov sib nqus (MT) yuav tsum tau ua kom paub tseeb tias cov kab nrib pleb thiab lwm yam tsis xws luag tau raug tshem tawm tag nrho.

3. Qhov sib tsoo qhov tob feem ntau yuav tsum tsis pub tshaj 5% ntawm cov khoom siv hauv paus thickness, thiab qhov txuas ntxiv ntawm cov vuam zoo thiab kev sib txuas rau cov khoom siv hauv paus yuav tsum tsis txhob raug puas tsuaj.

4. Txoj kev no tsis tas yuav tsum tau ua haujlwm kub, muaj kev pheej hmoo ntawm kev tsim kho tsawg, tsim nyog rau kev kho sai sai ntawm - qhov chaw kho mob, thiab yog txoj kev nyiam tsis yog - kev puas tsuaj.

II. Kho Vuam thiab Overlay Vuam - Rau qhov sib sib zog nqus los yog nkag mus rau qhov tsis xws luag
Thaum qhov tsis xws luag qhov tob yog qhov tseem ceeb, xws li kev nkag mus tsis tiav, tsis muaj fusion, porosity, slag inclusions, los yog sib sib zog nqus tawg, kho vuam los yog overlay vuam yog tsim nyog los kho cov khoom ncaj ncees.

1. Ua ntej, ua tib zoo tshem tawm qhov tsis xws luag siv carbon arc gouging lossis machining, kom ntseeg tau tias U-zoo li bevel nyob rau hauv qab. Tom qab tshem tawm, PT / MT kev kuaj pom tseeb tias tsis muaj qhov seem seem.

2. Preheating yuav tsum tau ua ntej vuam. Lub preheating kub nyob ntawm cov khoom thiab thickness, feem ntau 150-300 degree. Qhov kub ntawm qhov sib cuam tshuam yuav tsum tsis txhob qis dua qhov kub ntawm qhov preheating kom tsis txhob muaj qhov txias txias.

3. Siv cov khoom siv vuam uas zoo ib yam li lossis sib haum nrog cov khoom qub. Lub electrode txoj kab uas hla yuav tsum tsis txhob ntau tshaj Ø3.2mm los xyuas kom meej weld zoo.

4. Tom qab kho vuam, ua tib yam uas tsis yog- kuaj kev puas tsuaj (RT/UT/MT/PT) raws li qhov qub vuam. Tom qab-weld heat treatment tej zaum yuav tsim nyog los tshem tawm cov kev ntxhov siab uas seem.

Cov Lus Cim Tshwj Xeeb: Rau cov khoom siv uas muaj cov xov xwm tsis tshua muaj siab lossis muaj kev phom sij heev, cov thawv cryogenic, Cr-Mo steel ntim, thiab cov khoom siv ua rau muaj kev ntxhov siab, kev kho vuam yuav tsum nruj dua, thiab cov txheej txheem vuam yuav tsum tau ua raws li nruj me ntsis.

III. Kev Kho Kev Kho - Hais Txog Kev Puas Tsuaj Loj Hauv Ib Cheeb Tsam Thaum ib cheeb tsam loj nthuav tawm kev xeb, bulging, khoom deterioration, los yog rov kho tsis ua hauj lwm, patching yuav siv tau los hloov lub zog hauv zos- cov khoom siv bearing.

1. Qhov chaw tsis zoo yuav tsum raug tshem tawm tag nrho. Lub phaj phaj yuav tsum yog lub voj voog, elliptical, lossis duab plaub nrog lub kaum sab xis, nrog lub kaum sab xis ntawm tsis pub tsawg dua 100mm kom tsis txhob muaj kev ntxhov siab.

2. Cov khoom siv, tuab, thiab kev ua haujlwm ntawm lub phaj phaj yuav tsum ua raws li cov khoom siv hauv paus. Kev nthuav dav dawb thiab kev cog lus yuav tsum tau tso cai thaum lub sij hawm vuam los tiv thaiv kev ntxhov siab ntxiv.

3. Qhov ntev thaj yuav tsum tsis pub tsawg tshaj 300mm, thiab qhov kev ncua deb ntawm thaj tsam thiab nyob ib sab welds yuav tsum ntau tshaj peb npaug ntawm nominal phab ntsa thickness los yog ntau tshaj 100mm.

4. Thaum kho qhov tob tshaj li ib nrab ntawm phab ntsa thickness, yuav tsum tau rov ua dua raws li cov qauv xws li GB / T150.

Vim tias patching cuam tshuam nrog kev ua haujlwm vuam dav, nws yooj yim qhia cov vuam tsis xws luag thiab qhov seem seem, thiab tam sim no siv ceev faj, tsuas yog thaum tsim nyog kiag li.

IV. Component Hloov - Rau Irreversible Severe Defects
Thaum lub siab tseem ceeb-cov kabmob xws li lub tog raj kheej, lub taub hau, thiab cov nozzles nthuav tawm qhov tsis tuaj yeem tawg tawm, kev xeb hnyav, lossis rov kho tsis ua haujlwm, lawv yuav tsum tau hloov txiav txim siab.

1. Cov khoom siv hloov pauv yuav tsum ua tau raws li cov qauv tsim qauv, suav nrog cov khoom siv, cov lus qhia tshwj xeeb, thiab kev kho cua sov.

Thaum lub sij hawm installation, yuav tsum tau saib xyuas los tiv thaiv cov sealing nto thiab cov ntsiab lus sib txuas kom tsis txhob muaj kev puas tsuaj ntxiv.

2. Tom qab kev hloov pauv, tsis yog- kuaj kev puas tsuaj, kev sim siab, thiab kev sim ua haujlwm yuav tsum tau ua dua tshiab kom muaj kev nyab xeeb tag nrho.

Txoj kev no kim dua, tab sis nws tuaj yeem tshem tawm cov kev phom sij zais thiab tsim nyog rau cov xwm txheej uas yuav tsum muaj kev nyab xeeb siab.

V. Composite Materials thiab Mechanical Reinforcement - Kev Kho Mob Thaum Muaj Xwm Ceev

1. Kev kho cov khoom siv sib xyaw
Tsim nyog rau cov uas tsis yog - siab- cov cheeb tsam bearing lossis raws li kev ntsuas kub ceev ib ntus, xws li siv cov pa roj carbon fiber ntau + epoxy resin rau qhov sib txuas ntxiv.

Ua ntej kho, qhov sib txuas ntawm lub tank yuav tsum tau kho nrog kev tshem tawm cov xim, tshem tawm xeb, thiab degreasing kom ntseeg tau tias muaj zog sib khi.

Tom qab siv epoxy nplaum, nias thiab kho. Nws tuaj yeem muab tso rau hauv kev siv tom qab 48 teev ntawm chav tsev kub lossis 4 teev ntawm 80℃nrawm kho.

Txoj kev no tsis tas yuav qhib nplaim taws thiab tsim nyog rau kev sib khi sai sai hauv qhov chaw tawg thiab tawg, tab sis yuav tsum tsuas yog siv los ua txoj kev hloov pauv hloov.

2. Mechanical Reinforcement Siv thaum muaj xwm txheej ceev uas tsis tuaj yeem kaw lossis qhib nplaim taws, xws li siv segmented clamps ua ke nrog sealing nplaum kom ua tiav cov xaim xaim sealing.

T-bolts tau muab tso rau hauv qhov tawg thiab tig los kho nws, thiab tom qab ntawd nruj nreem nrog steel phaj thiab txiv ntseej kom ua tiav sai sai.

Lub sijhawm ua haujlwm yuav tsum tau tswj tsis pub dhau 30 feeb. Cov neeg ua haujlwm yuav tsum hnav lub tshuab ua pa kom muaj kev nyab xeeb.

VI. Kev tshuaj xyuas thiab kev lees paub Tom qab kho Tom qab txhua qhov kev kho tiav tiav, yuav tsum tau ua cov txheej txheem tshuaj xyuas nruj:

1. Kev tshuaj xyuas qhov muag: Paub meej tias qhov kev tsim cov vuam yog qhov zoo thiab tsis muaj qhov tsis xws luag xws li undercut, tawg, lossis porosity.

2. Tsis yog- kuaj kev puas tsuaj: Ua RT, UT, MT, lossis PT kuaj ntawm thaj chaw kho raws li tus qauv qub kom ntseeg tau tias tsis muaj kev puas tsuaj sab hauv tshaj li cov qauv.

3. Kev ntsuas siab: tshwj xeeb tshaj yog rau kev kho nrog qhov tob tshaj li ib nrab ntawm phab ntsa tuab, yuav tsum tau ua qhov kev ntsuas siab hydrostatic los yog pneumatic dua los xyuas qhov siab -cov kabmob muaj peev xwm.

4. Kev sim ua haujlwm: Txheeb xyuas qhov kev sib khi ua haujlwm, kev ua haujlwm siab, thiab qhov ntsuas kub kom ntseeg tau tias lawv zoo li qub.

Kev lees txais zaum kawg yuav tsum tau sau tseg thiab kos npe rau kev pom zoo, thiab suav nrog hauv cov khoom siv kev tswj xyuas cov ntaub ntawv.
