Kev soj ntsuam sab nraud
Kuj tseem hu ua nyob rau hauv - kev tshuaj xyuas kev pabcuam, qhov tseem ceeb ntawm qhov kev tshuaj xyuas no suav nrog: kuaj xyuas qhov chaw sab nraud ntawm lub nkoj siab rau txhua qhov tshwm sim txawv txav xws li tawg, deformation, leaks, lossis overheating hauv zos; xyuas kom meej tias cov khoom siv kev nyab xeeb ua tiav, teb, thiab txhim khu kev qha; xyuas kom meej tias fastening bolts tsis zoo thiab tag nrho nruj; thiab tshuaj xyuas qhov tsis zoo ntawm lub hauv paus, xws li kev tawg lossis tilting, nrog rau kev puas tsuaj rau cov txheej txheem tiv thaiv -corrosion. Kev tshuaj xyuas sab nraud yog lub luag haujlwm ua los ntawm cov neeg ua haujlwm soj ntsuam, thiab nws tseem yog ib qho kev soj ntsuam xyuas cov khoom siv rau cov neeg ua haujlwm. Yog tias muaj ib qho xwm txheej ua rau muaj kev pheej hmoo rau kev nyab xeeb yuav raug tshawb pom- xws li tawg lossis deformation hauv siab-cov khoom sib txuas, lossis cov dej xau loj heev- yuav tsum tau nres tam sim ntawd, thiab cov neeg ua haujlwm cuam tshuam tau ceeb toom yam tsis muaj kev ncua.
Kev soj ntsuam sab hauv thiab sab nraud
Kev tshuaj xyuas sab hauv thiab sab nraud ntawm cov hlab ntsha siab yuav tsum tau ua tsuas yog tom qab lub nkoj tau raug tshem tawm ntawm qhov kev pabcuam thiab ua kom huv si sab hauv. Ntxiv nrog rau kev npog tag nrho cov khoom suav nrog hauv kev tshuaj xyuas sab nraud, qhov tseem ceeb ntawm qhov kev ntsuam xyuas no suav nrog kev tshuaj xyuas qhov chaw sab hauv thiab sab nraud kom pom cov cim ntawm corrosion lossis puas. Tag nrho cov welds, lub taub hau hloov chaw, thiab lwm qhov chaw uas muaj kev ntxhov siab yog tshuaj xyuas - siv ob lub qhov muag liab qab thiab lub iav tsom iav - txhawm rau kuaj pom muaj cov kab nrib pleb; Thaum tsim nyog, kev kuaj ultrasonic lossis radiographic yog ua haujlwm los ntsuas qhov kev ncaj ncees sab hauv ntawm cov welds. Phab ntsa thickness ntsuas kuj coj. Yog hais tias qhov ntsuas phab ntsa thickness poob qis dua lub nkoj qhov tsawg kawg nkaus tso cai thickness, yuav tsum tau ua kom muaj zog re- xam, thiab cov lus pom zoo rau kev txo qis los yog kho qhov ntsuas yuav tsum tau npaj. Rau cov hlab ntsha uas cov kev khiav hauj lwm tej yam kev mob yuav induce hloov nyob rau hauv lub metallographic qauv ntawm cov khoom, metallographic tsom xam yuav tsum tau ua raws li qhov tsim nyog. Tsis tas li ntawd, rau siab -siab thiab ultra- siab- cov hlab ntsha siab, qhov tseem ceeb fastening bolts yuav tsum tau kuaj xyuas cov kab nrib pleb uas siv txoj hauv kev xws li sib nqus particle lossis dye penetrant testing. Ua raws li kev tshuaj xyuas sab hauv thiab sab nraud, qhov ua rau ntawm ib qho kev kuaj pom tsis zoo yuav tsum tau txheeb xyuas, thiab cov lus pom zoo kho kom tsim nyog. Ib qho rov-kev tshuaj xyuas yuav tsum tau ua tom qab kev kho tiav lawm. Lub sijhawm tshuaj xyuas tus qauv rau kev tshuaj xyuas cov hlab ntsha sab hauv thiab sab nraud yog ib zaug txhua peb xyoos; Txawm li cas los xij, rau cov hlab ntsha uas muaj cov kab mob corrosive heev los yog muaj kuab lom heev, lub sijhawm tshuaj xyuas no yuav tsum tau luv. Ib yam li ntawd, lub sijhawm tshuaj xyuas yuav tsum raug txo qis rau cov nkoj uas muaj qhov tsis xws luag tau tshawb pom thaum lub sijhawm ua haujlwm, nrog rau cov hlab ntsha uas pom cov khoom siv tsis zoo los yog cov khoom uas muaj cov ntaub ntawv tsis muaj pov thawj rau cov txheej txheem tshwj xeeb.
Kev tshuaj ntsuam xyuas
Ntxiv nrog rau cov khoom soj ntsuam uas tau teev tseg saum toj no, kev tshuaj xyuas dav dav ntawm lub nkoj siab xav tau kev ua haujlwm ntawm kev ntsuas siab (feem ntau yog kev sim hydrostatic). Tsis yog-Kev kuaj kev puas tsuaj (NDT) yog ua los ntawm kev ua piv txwv rau cov welds tseem ceeb, lossis - qhov yuav tsum tau ua - ntawm txhua qhov vuam. Txawm li cas los xij, rau cov nkoj uas muaj - siab tsawg, tsis yog -flammable, tsis yog - tshuaj lom, thiab tsis yog -corrosive media- tsis muaj qhov tsis xws luag tau kuaj pom thiab kev ua haujlwm txaus tau sau tseg- tsis yog - kuaj kev puas tsuaj yuav raug zam. Lub voj voog tshuaj ntsuam xyuas dav dav rau cov thawv ntim khoom feem ntau ua tsawg kawg ib zaug txhua rau xyoo. Rau cov ntim khoom tsim tau zoo tuav cov cua lossis cov pa roj tsis zoo- muab cov kev paub ua haujlwm txaus tau sau tseg thiab ib lossis ob qhov kev tshuaj xyuas sab hauv thiab sab nraud tau lees paub qhov tsis muaj corrosion- lub voj voog tshuaj ntsuam xyuas yuav raug ncua kom tsim nyog.
