Lub caij nplooj zeeg dhau los, ib tus ntawm peb cov kws tshaj lij ua haujlwm tau ya mus rau thaj chaw hnub ci hnub ci hauv tebchaws Philippines rau kev tshawb xyuas cov txheej txheem niaj hnub. Cov vaj huam sib luag tseem tab tom tsim, tab sis cov ceg txhawb nqa tau hais ib zaj dab neeg sib txawv. Pitting tau pib ntawm lub hauv paus daim hlau. Ob peb lub ntsia liaj qhov rooj sib txuas tau pom cov cim thaum ntxov ntawm galvanic hnav. EPC tus neeg cog lus tau ua raws li cov ntaub ntawv, tab sis ib puag ncig tsis tau.
Qhov kev mus ntsib ntawd tsis txawv. Ntawm Wuxi GRT Technology, peb tau pom ntau qhov haujlwm uas lub tshuab hluav taws xob txhawb nqa photovoltaic outlasted kev cia siab, thiab ob peb qhov twg corrosion los yog cov qauv qaug zog yuam kev hloov ntxov ntxov. Qhov sib txawv tsis tshua muaj nqis los rau ib qho khoom siv lossis txheej tuab. Nws yog ib txoj hauv kev txiav txim siab: xaiv cov khoom siv, kev ua qauv thauj khoom, nthuav dav, kev qhuab qhia kev teeb tsa, thiab kev tshaj tawm - kev kuaj xyuas. Hla ib qhov txuas, thiab 25-xyoo lav dhau los ua kev sib tw rau lub sijhawm.
Qhov no tsis yog phau ntawv theoretical. Nws yog cov ntsiab lus ntawm qhov peb tau kawm hauv av, hauv peb lub rooj cob qhia, thiab thoob plaws thaj chaw huab cua sib txawv. Yog tias koj tab tom tsim, qhia, lossis tswj lub hnub ci racking, ntawm no yog qhov ua tau txav lub koob rau ntev - lub sij hawm cia siab rau.
Lub Hidden Triggers: Yog vim li cas Mounts tsis ntev ua ntej Warranty tag
Corrosion thiab kev ua haujlwm tsis zoo tsis tshua tshaj tawm lawv tus kheej. Lawv pib me me, sib xyaw ua ke ntsiag to, thiab ntog tsuas yog thaum hloov cov nqi tshaj li kev tshuaj xyuas pob nyiaj siv.
Corrosion hauv PV kev txhawb nqa tshuab feem ntau ua raws li peb tus qauv:
- Atmospheric corrosion: Tsav los ntawm cov av noo, ntsev tsuag, thiab muaj kuab paug. Cov ntug dej hiav txwv thiab cov cheeb tsam chaw sov sov ua rau nws nrawm heev.
- Galvanic corrosion: tshwm sim thaum cov hlau tsis sib xws sib koom ib qho electrolyte (dej nag, condensation, los yog av noo). Aluminium rails bolted ncaj qha rau uncoated steel ncej yog ib qho tshwm sim.
- Crevice & pitting corrosion: Ncua dej hauv qab ntxhua khaub ncaws, hauv qhov ntsia liaj qhov rooj, lossis hauv qab cable ties tsim micro-ib puag ncig uas hla cov txheej tiv thaiv.
Lub cev qaug zog, ntawm qhov tod tes, feem ntau yog tsim los yog kev teeb tsa tsis sib haum:
- Underestimated dynamic cua loads
- Cov kua dej tsis zoo uas ntxiv cov khoom tuag los yog tsim cov hnab ntim dej khov hauv cov huab cua txias
- Tshaj -Torqued fasteners uas tawg cov txheej tiv thaiv los yog sawb xov
- Kev vibration los ntawm inverters lossis cov tshuab nyob ze hloov mus rau hauv cov ntsiab lus mounting
Peb tsis kho cov no raws li cov teeb meem cais. Hauv peb cov kev tshuaj xyuas engineering, peb qhia lawv ua ke. Lub bracket uas tuab txaus rau cua load tab sis tsis zoo kaw yuav corrode sai dua. Ib tug zoo kawg nkaus coated ceg uas yog anched rau hauv hloov av yuav qaug zog ntawm lub hauv paus. Kev tiv thaiv pib nrog pom qhov system ua ib qho kev sib txuas ntawm cov qauv.
Kev xaiv cov khoom tsis yog tsuas yog ib daim ntawv qhia tshwj xeeb xwb
Kub-dip galvanizing, anodized aluminium, magnesium-aluminium-zinc txheej, stainless hlau fasteners… cov kev xaiv yog paub. Tab sis txoj kev xaiv yog nyob ntawm qhov chaw, tsis yog lub catalog.
Ntawm Wuxi GRT Technology, peb faib cov cheeb tsam uas siv ISO 12944 cov qauv ua ntej peb tseem qhib cov ntaub ntawv CAD. Ib qhov chaw C3 hauv av hauv Central Europe muaj qhov sib txawv ntawm qhov sib txawv ntawm C5-M marine site nyob rau sab hnub tuaj Asia. Nov yog yuav ua li cas peb txhais qhov ntawd rau hauv specs:
- Txheej thickness tseem ceeb, tab sis kev pab them nqi tseem ceeb dua. Ib txheej 65μm galvanized tsis muaj txiaj ntsig yog tias qhov chaw vuam, ntu ntu, lossis cov qhov drilled tsis raug kho. Peb xav tau kev tshaj tawm -fabrication kov- cov txheej txheem siv zinc-nplua nuj primers pom zoo los ntawm cov khoom txheej txheej.
- Fasteners dictate lub neej ntev. Peb tau pom cov haujlwm ua tsis tiav vim tias carbon steel bolts tau siv nrog aluminium profiles. Txawm tias nrog sealant washers, capillary nkaus rub ya raws rau hauv xov. Peb lub hauv paus rau kev ua haujlwm ntawm ntug dej hiav txwv: A2 / A4 stainless lossis hnyav coated bolts nrog lub tes tsho cais.
- Aluminium vs. steel tsis yog qhov nyiam, nws yog kev suav. Aluminium resists atmospheric corrosion zoo tab sis qaug zog sai dua nyob rau hauv cyclic cua loads. Hlau nqa ntau dua li qub loads tab sis xav tau kev tiv thaiv corrosion. Peb feem ntau hybridize: steel lub ntsiab ob txhais ceg rau compressive zog, aluminium rails rau vaj huam sib luag interface thiab hnyav txo, nrog dielectric pads ntawm kev sib cuag cov ntsiab lus.
Peb tsis pom zoo "kho kom zoo dua" cov ntaub ntawv dig muag. Tshaj -Specing nce tus nqi yam tsis muaj txiaj ntsig zoo. Hauv qab - specing guarantees teb callbacks. Qhov nyiaj tshuav yog los ntawm ib puag ncig daim ntawv qhia + load simulation + tiag - ntiaj teb kev teeb tsa.
Tsim cov ntsiab lus uas txiav txim siab 25-Xyoo ciaj sia taus
