Taug qab kev photovoltaic bracket
Qhov kev taug qab hom photovoltaic bracket txav mus rau photovoltaic array nrog rau qhov hloov ntawm qhov teeb meem lub kaum sab xis ntawm lub hnub dhau los ntawm lub tshuab electromechanical lossis hydraulic kom lub hnub ci tuaj yeem ua tau ncaj qha rau cov vaj huam sib luag ntawm cov module, thiab cov photovoltaic array lub zog tsim muaj peev xwm yog txhim kho. Raws li tus naj npawb ntawm cov khoom taug qab, nws tuaj yeem muab faib ua ib-kab ib leeg taug qab cov kab ke sib txuas thiab ob-kab nruab zog.
1.Qhov ncaj qha-axis ib txoj kab ke nrhiav
Lub photovoltaic square array tuaj yeem taug qab lub hnub raws txoj kab tav toj nyob rau sab hnub tuaj-sab hnub poob kom tau txais ntau lub zog ntawm kev tsim hluav taws xob, uas tau siv dav hauv thaj chaw qis qis. Raws li qhov pom los yog tsis muaj lub kaum sab xis ntawm sab qaum teb mus rau sab qab teb, nws tuaj yeem muab faib ua hom tsis pub dhau kev soj qab taug qab thiab hom kev sib tw yam tsis muaj dab tsi nrog rau sab.
2.The oblique ib-axis nrhiav kev ua haujlwm
Lub mus txog qhov ntsuas raug teem rau qee lub kaum sab xis tig rau sab qab teb thaum tig mus rau sab hnub tuaj-sab hnub poob, thiab lub hnub ci azimuth kaum sab xis yog taug qab ncig qaij axis kom tau txais lub zog ntau dua, uas tsim nyog rau cov ntawv thov nyob hauv latitudes siab dua.
3.Dual-axis nrhiav kev ua haujlwm
Ob-axis kev sib hloov (txoj kab ntsug, kab rov tav) yog siv los taug qab lub hnub ci duab hluav taws xob hauv lub sijhawm tiag tiag kom paub meej tias lub hnub ci duab hluav taws xob yog qhov txiav txim siab rau lub module pawg nto rau txhua lub sijhawm, yog li kom tau txais lub zog ntau tshaj plaws, tsim rau siv nyob rau hauv ntau yam latitudes.
4. Sib piv ntawm ntau lub voj voog ua haujlwm hom
Sib piv ntawm photovoltaic bracket steel thiab txhuas thiab khoom siv zog
Lub laj kab feem ntau yog ua los ntawm Q235B steel thiab txhuas me me txuas ntxiv profile 6063 T6. Hais txog lub zog, 6063 T6 aluminium alloy yog li 68% -69% ntawm Q235 B steel. Yog li no, cov hlau feem ntau zoo rau txhuas lub cev nyob rau hauv cov cheeb tsam cua thiab qhov loj. Kev Profile.
Lub txim dab tsi
Lub deflection ntawm cov qauv yog cuam tshuam nrog cov duab thiab qhov loj me ntawm cov profile thiab elastic modulus (qhov ntsuas qhov tsis suav qhov khoom) thiab tsis cuam tshuam ncaj qha rau lub zog ntawm cov khoom.
Raws li cov xwm txheej qub, qhov deformation ntawm aluminium alloy profiles yog 2.9 npaug ntawm cov hlau, thiab qhov hnyav yog 35% ntawm cov hlau. Hais txog cov nqi, cov khoom siv aluminium yog 3 zaug ntawm cov hlau. Yog li no, feem ntau hauv cov cheeb tsam cua hlob, qhov nrug yog qhov loj me, tus nqi thiab lwm yam mob ntawm cov hlau zoo dua li aluminium alloy profiles.
Anti-corrosion
Tam sim no, lub ntsiab tiv thaiv kev xeb ntawm cov hlau yog 55-80μm galvanized steel thiab 5-10μm anodized aluminium alloy.
Aluminium alloy yog nyob rau thaj chaw passivation nyob rau hauv qhov chaw ib puag ncig, thiab cov zaj duab xis oxide tuab yog tsim rau saum npoo, uas tiv thaiv cov nplaim ntawm cov txhuas ua kom nrov tau los ntawm kev tiv toj ib puag ncig ntawm ib puag ncig, yog li nws muaj kev txhim kho zoo corrosion, thiab corrosion tus nqi nce nrog lub sijhawm. Thaum txu zuj zus.
Raws li qhov xwm txheej ib txwm (C1-C4 ib puag ncig), lub tuab ntawm galvanized 80μm tuaj yeem lav rau ntau tshaj 20 xyoo, tab sis qhov xeb xeb yuav ua kom nrawm hauv qhov chaw muaj huab cua ntau lossis chaw siab rau hiav txwv thiab txawm tias muaj dej hiav txwv. Saum toj no thiab yuav tsum tau saib xyuas tas li txhua xyoo.
Aluminium tseem zoo tshaj rau cov hlau ntau ntxiv yog hais txog kev tiv thaiv corrosion.
Sib piv ntawm lwm yam
(1) Txheeb Xyuas:
Muaj ntau hom kev kho saum npoo rau aluminium alloy profiles, xws li anodizing, tshuaj polishing, tshuaj pleev xim fluorocarbon, pleev xim rau xim electrophoretic, thiab lwm yam zoo nkauj tsos thiab tuaj yeem hloov mus rau ntau qhov chaw muaj zog corrosive.
Cov hlau feem ntau yog kub-dip galvanized, nto txau, thiab pleev xim. Cov tsos yog zuj zus tshaj li txhuas cov ntawv siv ntawm txhuas. Nws tseem yog qis dua rau aluminium profiles nyob rau hauv cov nqe lus ntawm kev tiv thaiv corrosion.
(2) Hla-ntu muaj ntau haiv neeg
Cov txheej txheem dav dav ntawm aluminium alloy profiles suav nrog extrusion, casting, khoov thiab stamping. Extrusion ntau lawm tam sim no tau tsim cov qauv kev tsim tawm ntau. Los ntawm kev qhib lub extrusion tuag, nws tuaj yeem ua tiav qhov tsim txhua yam kev hla ntu ntawm cov khoom siv, thiab cov khoom siv ceev yog qhov ceev heev.
Cov hlau feem ntau kuav los tiag, nrum, khoov, txhav, thiab lwm yam. Kev txiav txim siab yuav tsum tau muab kho los ntawm kev siv lub tshuab log, tab sis tom qab lub tshuab hloov, nws tuaj yeem tsim cov khoom lag luam zoo ib yam nkaus xwb, thiab qhov loj me tuaj yeem hloov kho, thiab cov duab ntoo khaub lig tuaj yeem hloov tsis tau, xws li C-zoo li hlau. , Z-puab hlau, thiab lwm seem. Tus txheej txheem dov ntau lawm kuj tsau thiab qhov ntau lawm kuj raug ceev.
Rov qab cov khoom siv
Kev saib xyuas tus nqi ntawm cov qauv vaj tsev steel nce ntxiv 3% txhua xyoo, thaum lub qauv aluminium txhawb yuav tsum tsis muaj kev saib xyuas thiab txij nkawm, thiab cov khoom siv aluminium tseem muaj 65% rov qab cov nqi tom qab 30 xyoo. Aluminium tus nqi yuav tsum nce ntxiv li 3% txhua xyoo. Tom qab 30 xyoo, nws yog pib ua ib pawg ntawm cov ntawv hlau uas tsis tas rov ua tus nqi.
Muaj kev sib piv ntawm kev ua tau zoo
(1) Aluminium alloy profiles yog lub teeb nyob rau hauv qhov hnyav, zoo nkauj nyob rau hauv tsos, thiab zoo heev nyob rau hauv anti-corrosion kev ua tau zoo. Lawv feem ntau siv rau hauv tsev cov hluav taws xob vov tsev uas yuav tsum tau thauj cov kabmob thiab muaj zog tiv thaiv ib puag ncig.
(2) Cov hlau muaj qhov siab ua kom siab thiab me me deflection thaum raug thauj. Nws feem ntau siv rau hauv cov chaw nres tsheb fais fab lossis qhov chaw nrog lub zog loj.
(3) Tus Nqi: Feem ntau, qhov pib qhov cua ceev qis yog 0.6kN / m2 thiab qhov luv tshaj 2m. Tus nqi ntawm aluminium alloy bracket yog 1.3-1.5 npaug dua li ntawm cov qauv sib tsoo steel. Hauv qhov nruab nrab me me, (xws li cov xim steel ru tsev), tus nqi sib txawv ntawm cov txhuas hlau pawg thiab cov qauv ntsuas hlau tsis sib thooj, thiab cov khoom siv aluminium alloy yuav sib zog ntau dua li cov hlau tsis sib haum hauv qhov hnyav, yog li nws haum rau tsev nres tsheb fais fab hauv tsev.
