Txawm tias feem ntau precisely fabricated welded steel ncej yuav underperform yog hais tias installation yog mishandled. Kev npaj qhov chaw kom zoo, theem, kev thauj mus los, thiab tom qab- kev tshuaj xyuas kev teeb tsa yog qhov tseem ceeb rau kev ua tiav cov qauv kev ncaj ncees uas tus tsim tsim tsim. Cov lus qhia no suav nrog cov txheej txheem kev teeb tsa, cov teeb meem tshwm sim, thiab qhov tseeb -cov ntaub ntawv tshawb fawb thoob ntiaj teb tau kos los ntawm peb 20+ xyoo ntawm kev tsim khoom ua haujlwm pabcuam Australian B2B kev ua lag luam.
Lub luag haujlwm tseem ceeb ntawm Vuam Zoo hauv Base Plate Performance
Ua ntej kev teeb tsa pib, nws yog ib qho tseem ceeb kom paub tseeb tias cov welded puag daim hlau ua tau raws li qhov tshwj xeeb. Lub hauv paus phaj yog qhov sib cuam tshuam ntawm cov ncej steel thiab lub hauv paus pob zeb-txhua qhov kev cuam tshuam ntawm qhov kev sib tshuam no cuam tshuam rau tag nrho cov qauv kev thauj mus los.
Qhov tseem ceeb hauv paus phaj weld soj ntsuam cov ntsiab lus suav nrog:
Weld caj pas thickness:Yuav tsum ua kom tau raws li lossis tshaj qhov tsawg kawg uas tau teev tseg hauv daim duab engineering. Hauv qab - caj pas welds txo cov peev xwm sib koom ua ke.
Hauv paus nkag:Rau tag nrho -kev nkag welds, xyuas kom tiav cov hauv paus fusion. Incomplete penetration tsim kev ntxhov siab concentration cov ntsiab lus uas ua rau qaug zog tawg.
Weld ntiv taw geometry:Kev hloov pauv ntawm cov ntiv taw ntiv taw (luv taws ntau dua lossis sib npaug li 1 hli) txo cov kev ntxhov siab ntau txog li 40% piv rau cov ntse ntse.
Qhov defects:Tsis muaj kab nrib pleb, porosity, lossis undercut tshaj 0.5mm qhov tob ntawm AS / NZS 1554.1 kev lees paub.
Kev Npaj ntawm qhov chaw thiab cov kev xav tau hauv lub hauv paus
Kev vam meej pib pib nrog lub hauv paus. Cov ntsiab lus tseem ceeb:
Pob zeb muaj zog:Yam tsawg kawg nkaus 25 MPa (feem ntau yog 32 MPa rau cov khoom siv hnyav). Cia 28-hnub kho ua ntej thav duab installation.
Nto flatness:Foundation nto yuav tsum tiaj tus nyob rau hauv ± 3 hli ib 'meter'. Siv cov uas tsis yog -shrink grout los them rau qhov me me qhov tsis sib xws.
Anchor bolt qhov chaw:Template- teem caij thauj tog rau nkoj bolts thaum lub pob zeb nchuav. Txheeb xyuas tus qauv ntsia liaj qhov rooj tiv thaiv ncej puag phaj qhov - kam rau ua ± 5mm nyob rau hauv txhua qhov kev taw qhia.
Dej ntws:Xyuas kom lub hauv paus slopes deb ntawm lub hauv paus ncej los tiv thaiv cov dej tsub zuj zuj, uas accelerates corrosion ntawm steel - pob zeb interface.
Txoj Kev Txhim Kho
Txoj Kev 1: Grout-Bedded Installation (pom zoo rau cov cuab yeej hnyav)
Tso lub thav duab rau ntawm daim hlau hloov tau (feem ntau 50 × 50mm steel shims) ntawm txhua qhov chaw thauj tog rau nkoj.
Theem tus ncej siv precision siab qib lossis laser qib. Lub hom phiaj: ± 1mm ib 'meter' nyob rau hauv ob qho tib si qhia.
Torque thauj tog rau nkoj bolts rau cov nqi teev (feem ntau 50-80% ntawm qhov kawg torque rau thawj qhov chaw).
Ncuav tsis yog -shrink cementitious grout (tsawg kawg 25 MPa) nyob rau hauv lub hauv paus phaj, ua kom tiav kev pab them nqi uas tsis muaj voids. Siv grout qhov yog lub hauv paus phaj siab tshaj 600mm nyob rau hauv txhua qhov ntev.
Tom qab grout kho (24-48 teev), siv qhov kawg torque rau thauj tog rau nkoj bolts nyob rau hauv lub hnub qub qauv sib lawv liag.
Txoj Kev 2: Direct Bearing Installation (Rau Lighter Frames)
Siv ib txheej ntawm epoxy mortar los yog qhuav - pob grout rau lub hauv paus nto.
Txo cov thav duab mus rau qhov chaw npaj, ua raws li cov khoom thauj tog rau nkoj.
Theem thiab kho tus ncej, ces torque bolts rau specification.
Kaw lub hauv paus phaj perimeter nrog silicone sealant kom tsis txhob ya raws nkag mus.
Case Study: Mining Equipment Base Frame Installation
Ib txoj haujlwm tsis ntev los no tau koom nrog kev tsim thiab txhim kho qhov hnyav -cov haujlwm welded steel puag ncej rau cov khoom siv ntxhia ua cov khoom hla ntawm thaj chaw Western Australian mine. Lub thav duab, fabricated los ntawm Q345 steel phaj (25mm cov tswv cuab tseem ceeb, 16mm gussets), ntsuas 4.2m × 2.8m × 1.5m thiab hnyav 3.2 tonnes.
Cov ntsiab lus tseem ceeb ntawm kev tsim khoom:
Robotic SAW welding rau cov txheej txheem tseem ceeb ntawm cov pob qij txha kom ntseeg tau tias muaj kev nkag mus zoo ib yam ntawm cov phaj tuab
Tshaj tawm -weld kev ntxhov siab nyem ntawm 600℃rau 2 teev kom txo qis kev ntxhov siab
Thaum kawg machining ntawm sab saum toj mounting nto kom ua tiav flatness ntawm 0.3mm hla tag nrho 4.2m ntev
AS/NZS 4680 kub-dip galvanizing rau 50+ xyoo tiv thaiv corrosion nyob rau hauv mine qhov hnyav ib puag ncig
Installation tshwm sim:Lub thav duab tau teeb tsa rau ntawm 32 MPa pob zeb pob zeb siv cov grout-txoj kev txaj. Tag nrho lub sij hawm installation: 6 teev (tsis suav nrog grout curing). Tom qab- kev teeb tsa NDT tau lees paub tias tsis muaj vuam degradation thaum thauj thiab teeb tsa. Lub thav duab tau ua haujlwm tas li rau 18 lub hlis uas tsis muaj teeb meem kev teeb tsa.
Tshaj tawm -Kev Tshawb Fawb Kev Tshawb Fawb
Txheeb xyuas tus ncej: ± 1mm / m hauv ob qho kev qhia
Xyuas tag nrho cov thauj tog rau nkoj bolt torques raws li specification
Tshawb xyuas grout rau voids los yog cracking
Txheeb xyuas qhov kev ncaj ncees ntawm cov phaj hauv qab - mus rau -Kem kev sib txuas (visual + MT yog tias tau teev tseg)
Paub meej tias HDG txheej kev ncaj ncees- tsis muaj kev puas tsuaj thaum lub sijhawm teeb tsa
Cov ntaub ntawv raws li - tsim qhov ntev thiab cov ntaub ntawv teeb tsa rau kev xa mus rau qhov project
Ntsiab Cai
Weld zoo ntawm lub hauv paus phaj kev sib txuas yog qhov tseem ceeb -xyuas caj pas tuab, hauv paus nkag, thiab ntiv taw geometry ua ntej kev teeb tsa
Grout-bedded installation yog pom zoo rau cov khoom hnyav thav ntawv; direct bearing suits cov kev siv sib dua
Lub hauv paus flatness nyob rau hauv ± 3mm / m thiab muab tso rau thauj tog rau nkoj bolts kom zoo tsis yog -kev sib tham ua ntej
Ncej -weld kev nyuaj siab nyem thiab zaum kawg machining kom ntev -lub sij hawm seem stability
Ib txwm ua tom qab- kev tshuaj ntsuam xyuas thiab cov ntaub ntawv raws li - tsim
