Yuav ua li cas thiaj nrhiav tau cov kab nrib pleb hauv lub nkoj siab?

I. Kev Tshawb Fawb Ua Ntej: Kev Tshuaj Xyuas Kev Pom Zoo (tseem siv tau rau pom cov kab nrib pleb)

Ua ntej kev sim kev tshaj lij, kev tshuaj xyuas sai tuaj yeem ua tau siv qhov muag liab qab lossis cov cuab yeej pabcuam txhawm rau txheeb xyuas qhov txawv txav.

1. Kev Tshuaj Xyuas Kev Pom Zoo: Siv qhov muag liab qab lossis 5-10x lub iav tsom iav kom pom qhov chaw muaj kev ntxhov siab xws li welds, nozzles, thiab qhov kawg ntawm kev hloov chaw. Cov kab nrib pleb feem ntau tshwm sim li nyias, elongated kab thiab tej zaum yuav nrog los ntawm xeb, to, los yog discoloration.

2. Txoj kev teeb pom kev zoo: ci lub teeb ci sib npaug rau lub nkoj nto, siv qhov sib piv ntawm lub teeb thiab duab ntxoov ntxoo kom pom cov qhov me me lossis cov kab nrib pleb.

3. Kev Ntsuas Rauj: Maj mam coj mus rau lub nkoj phab ntsa nrog rauj 0.5kg. Lub suab npub los yog qhov txawv txav ntawm qhov xav tau qhia tias tuaj yeem ua rau sab hauv delamination lossis tawg.

✅ Cov xwm txheej siv tau: Kev tshuaj xyuas niaj hnub, kev tshuaj xyuas kaw, lossis raws li kev ntsuas ua ntej ua ntej tsis yog - kev sim ua kom puas tsuaj.

II. Kev kuaj pom tseeb: Tsis yog-Kev Ntsuam Xyuas Kev Puas Tsuaj (NDT) Technology (Tsoom Fwv Teb Chaws thiab Cov Cwj Pwm)

Thaum tshawb pom qhov chaw tsis txaus ntseeg lossis thaum lub sijhawm tshuaj xyuas raws li cov txheej txheem, NDT thev naus laus zis yuav tsum tau siv rau kev ntsuam xyuas meej.

1. Sib Nqus Particle Test (MT) – Nyiam rau cov ntaub ntawv Ferromagnetic

Lub hauv paus ntsiab lus: Tom qab magnetization, ib qho hluav taws xob sib nqus yog tsim ntawm qhov tawg, nyiam cov khoom sib nqus rau kev loj hlob.

Qhov zoo: Siab rhiab heev rau saum npoo thiab ze ntawm - cov kab nrib pleb, tshwj xeeb tshaj yog haum rau cov pa roj carbon steel thiab qis - cov thawv hlau alloy.

Daim ntaub ntawv: Feem ntau siv rau kev ntxhov siab corrosion nrhiav kom pom nyob rau hauv siab -lub zog steel thiab heev tawg- cov ntaub ntawv rhiab heev; fluorescent magnetic particles yooj yim dua los txheeb xyuas hauv qab lub teeb dub.

2. Kev Ntsuam Xyuas Penetrant (PT) - General -Lub Hom Phiaj Qhib Qhov Ncauj Kev Tshawb Nrhiav

Lub hauv paus ntsiab lus: Penetrant nkag mus rau qhov tawg; Tom qab ntxuav, tus tsim tawm yog siv los qhia qhov tsis xws luag.

Qhov zoo: Muaj feem xyuam rau ntau yam hlau thiab tsis yog- cov khoom sib nqus; kev ua haujlwm yooj yim.

Txwv tsis pub: Tsis tuaj yeem ntes kaw cov kab nrib pleb lossis cov teeb meem sab hauv.

3. Ultrasonic Testing (UT) – A "X-ray Vision" rau Internally Buried Cracks

Lub hauv paus ntsiab lus: Siab - zaus suab nthwv dej cuam tshuam tawm cov kab nrib pleb, thiab qhov chaw thiab qhov tob yog txiav txim siab los ntawm cov teeb liab ncha.

Qhov zoo: Muaj zog nkag mus rau lub zog; muaj peev xwm txheeb xyuas cov kab nrib pleb hauv tuab - cov thawv ntim; kev ua haujlwm siab.

Kev pom zoo: Rau cov kab nrib pleb sab hauv, kev kuaj ultrasonic yog txoj kev nyiam.

4. Radiographic Testing (RT) – Direct Imaging of Internal Weld Defects

Lub hauv paus ntsiab lus: X-rays lossis gamma rays nkag mus rau hauv lub thawv; tus nqi nqus nws txawv ntawm qhov chaw tawg, tsim cov duab ntawm zaj duab xis.

Qhov zoo: Cov txiaj ntsig zoo; khaws cia mus tas li; haum rau weld zoo ntsuam xyuas.

Kev txwv: Cov khoom siv siab heev; kev tiv thaiv hluav taws xob nruj heev.

5. Cov thev naus laus zis tshiab txhim kho kev tshawb pom kev ua tau zoo

Ultrasonic Guided Wave Testing: Muaj peev xwm ncav cuag qhov kev ncua deb ntawm kaum ntawm meters, haum rau kev tshuaj xyuas sai ntawm cov ntim loj; tau ntse kuaj pitting tsis xws luag ntxaum tshaj 2 hli.

Phaseed Array Ultrasonic Testing: Electronic scanning + 3D duab; raug qhov chaw qaug zog tawg mus rau 0.5mm qib nrog qhov yuam kev tsawg dua 0.1mm.

Circumferential Guide Wave Positioning Model: Tshwj xeeb yog tsim los rau tsis yog -kev puas tsuaj ntawm cov kab nrib pleb hauv cov kav dej siab, ua kom muaj kev tshuaj xyuas cyclic.

III. Qhov Chaw Tshawb Fawb Tseem Ceeb: Txhim Kho Lub Hom Phiaj Tshuaj Ntsuam Xyuas
Cov cheeb tsam hauv qab no yog siab -kev pheej hmoo rau cov kab nrib pleb thiab yuav tsum suav nrog cov ntsiab lus uas yuav tsum tau soj ntsuam:

Welds thiab cua sov- thaj chaw cuam tshuam (tshwj xeeb yog thaj chaw uas yuav tsum tau kho ntau yam)

Nyob ib ncig ntawm nozzles thiab qhib

Hloov chaw ntawm lub kaus mom kawg thiab lub tog raj kheej

Kev ntxhov siab ntau qhov chaw xws li kev txhawb nqa thiab flanges

Cov cheeb tsam nyob rau hauv ntev - kev sib cuag nrog cov xov xwm corrosive los yog nyob rau hauv thermal cycling
IV. Cov Teeb Meem Ua Haujlwm Tsis Txaus Siab: Indirectly txheeb xyuas qhov muaj peev xwm tawg
Txawm hais tias cov kab nrib pleb tsis raug kuaj pom ncaj qha, cov xwm txheej hauv qab no qhia tias muaj peev xwm latent tsis xws luag:

Nquag kev nyab xeeb valve tripping lossis txawv txav siab hloov pauv

Periodic leakage ntawm flanges thiab welds

Qhov ntsuas kub tsis zoo hauv cheeb tsam nce ntxiv (kuaj nrog infrared thermal imagers)

Ua kom muaj kev vibration lossis suab nrov txawv txav
