Raws li lub ntsiab lus tseem ceeb ntawm kev thauj khoom-cov kabmob thiab kho qhov system, qhov zoo ntawm cov hlau txhawb nqa ncaj qha cuam tshuam rau kev nyab xeeb thiab ruaj khov ntawm tag nrho cov qauv. Txhawm rau kom ntseeg tau tias kev ua tau zoo ntawm kev txhawb nqa thav duab nyob rau hauv cov qauv tsim, kev hloov pauv ib puag ncig, thiab kev siv lub sijhawm ntev -, tsim kom muaj txheej txheem tshuaj xyuas kev tshawb fawb thiab nruj yog qhov tseem ceeb heev. Kev tshuaj xyuas kev ua haujlwm nthuav tawm cov txheej txheem tsim khoom, kev teeb tsa, thiab kev pabcuam, ua haujlwm rau ob qho tib si los ntawm kev txheeb xyuas qhov kev tsim khoom zoo thiab kev tiv thaiv kev pheej hmoo; nws standardization tau dhau los ua kev pom zoo ntawm kev lag luam.
Cov txheej txheem tshuaj xyuas feem ntau pib nrog kev tshuaj xyuas cov khoom tuaj. Cov theem no tsom mus rau kev txheeb xyuas seb cov qib steel, cov khoom siv kho tshuab, thiab cov tshuaj muaj pes tsawg leeg ua tau raws li cov qauv tsim. Tensile, dabtsi yog khoov, thiab kev ntsuam xyuas cuam tshuam yog ua los ntawm cov qauv los ntsuas lawv lub zog, ductility, thiab toughness. Rau kev txhawb nqa thav duab nrog cov huab cua tshwj xeeb los yog kev tiv thaiv corrosion, txheej thickness, adhesion, thiab tsis kam mus rau ntsev tsuag, acids, thiab alkalis yuav tsum tau kuaj xyuas kom ntseeg tau tias cov kev tiv thaiv mus txog nws lub neej kev cia siab. Kev soj ntsuam cov khoom dhau los yog qhov yuav tsum tau ua ua ntej rau cov txheej txheem tom ntej.
Kev tsim cov txheej txheem tshuaj xyuas theem feem ntau tsom rau kev tsim kom raug thiab kev sib txuas zoo. Welded kev txhawb nqa yuav tsum tau tshuaj xyuas qhov tsis xws luag xws li tawg, porosity, thiab slag inclusions nyob rau hauv weld tsos, thiab tsis yog -kev kuaj kev puas tsuaj, xws li kev ntsuam xyuas ultrasonic los yog radiographic kuaj, yuav tsum tau ua raws li cov qauv txhawm rau txheeb xyuas qhov tsis xws luag sab hauv. Rau kev txhawb nqa bolted, qhov kam rau ua, nruj torque, thiab tiv thaiv - loosening ntsuas yuav tsum tau txheeb xyuas kom tsis txhob xoob thiab tsis ua hauj lwm vim kev sib dhos yuam kev lossis tsis txaus preload. Dimensional ntsuas npog cross-sectional dimension, length, angles, and flatness kom ntseeg tau tias muaj kev sib haum xeeb nrog cov duab kos thiab kom ua tau raws li kev sib dhos thiab thauj khoom- bearing yuav tsum.
Kev ntsuas kev ua tau zoo yuav tsum tau ua ua ntej cov khoom tiav tawm hauv lub hoobkas. Ntxiv rau qhov rov- tshuaj xyuas qhov loj me thiab qhov tshwm sim, simulated load tests tuaj yeem ua, siv qhov ntsuas lossis qhov kawg loads los soj ntsuam kev txhawb nqa deformation thiab kev ntxhov siab faib, xyuas seb nws cov load- bearing muaj peev xwm thiab nruj raws li cov qauv. Rau kev txhawb nqa siv rau seismic los yog cua tsis kam, dynamic teb kev ntsuam xyuas kuj yuav tsum tau soj ntsuam stability nyob rau hauv vibration los yog mem tes loads. Tag nrho cov ntaub ntawv xeem yuav tsum tau sau tag nrho raws li lub hauv paus rau kev traceability thiab ntawv pov thawj zoo.
Ntawm - qhov kev kuaj xyuas qhov chaw yog kab kawg ntawm kev tiv thaiv kom ntseeg tau tias qhov ua tau zoo ntawm kev txhawb nqa. Ua ntej kev teeb tsa, qhov flatness ntawm lub hauv paus, qhov chaw ntawm qhov chaw embedded, thiab qhov chaw qhov ntev ntawm qhov kev txhawb nqa yuav tsum raug txheeb xyuas kom tsis txhob muaj kev sib txawv ntawm kev tsim kho los ntawm kev ua kom tsis muaj zog ntawm txoj kev sib kis. Thaum lub sij hawm installation, kev tsim kho zoo ntawm kev sib txuas ntawm cov nodes yuav tsum tau saib xyuas, tshwj xeeb tshaj yog kev tiv thaiv cua txias ntawm cov chaw welded thiab kev tswj kom zoo ntawm qhov kawg bolt nruj. Tom qab kev teeb tsa, tag nrho cov kev kho geometric thiab kev kuaj xyuas kev thauj khoom yuav tsum tau ua kom paub meej tias lub cev muaj zog thiab kev ntxhov siab ntawm kev txhawb nqa hauv kev ua haujlwm raws li cov qauv tsim.
Kev tshuaj xyuas tsis tu ncua thaum lub sijhawm ua haujlwm pabcuam yog qhov tseem ceeb sib npaug. Lub voj voog soj ntsuam yuav tsum tau txiav txim siab raws li ib puag ncig thiab kev pabcuam lub neej txwv, tsom rau kev kuaj xyuas corrosion, txheej kev ncaj ncees, thiab kev qaug zog ntawm cov welds thiab connectors. Cov cheeb tsam uas muaj ntau deformation, tawg, los yog corrosion yuav tsum tau kho los yog hloov tam sim ntawd kom tsis txhob muaj deformation expansion thiab cascading tsis ua hauj lwm. Cov kev tshuaj ntsuam xyuas tuaj yeem ua ke nrog kev tshuaj xyuas qhov muag, tsis yog-kev kuaj kev puas tsuaj, thiab kev soj ntsuam kev ntxhov siab los tsim ib qho kev ntsuas kev noj qab haus huv.
Zuag qhia tag nrho, cov txheej txheem kev soj ntsuam xyuas hlau ua raws cov kab tseem ceeb los ntawm cov khoom siv rau kev tsim khoom, cov khoom tiav, kev teeb tsa, thiab kev pabcuam, nrog rau txhua kauj ruam sib cuam tshuam thiab raug tswj xyuas nruj. Nws tso siab rau cov cuab yeej ntsuas siab thiab cov txheej txheem, nrog rau kev tswj xyuas nruj thiab kev ua raws li tus qauv. Kev txhawb nqa kev tsim qauv thiab kev txawj ntse ntawm cov txheej txheem tshuaj xyuas yuav ua kom muaj kev cuam tshuam zoo rau kev siv cov kev txhawb nqa hlau txhim khu kev qha hauv ntau yam.
