A transformer radiatorTej zaum yuav zoo li yooj yim, tab sis kev yuav khoom tsis raug tuaj yeem ncua kev hloov pauv, FAT thiab xa khoom.
Cov teeb meem tshwm sim tsis tshua pom nyob rau hauv cov lus hais: tsis muaj peev xwm ua kom txias tsis txaus, qhov chaw flange tsis raug, qhov sib txuas me me, cov coatings tsis zoo lossis cov vaj huam sib luag puas tom qab kev thauj mus los hauv hiav txwv.
Rau transformer manufacturers muab rau cov teb chaws Asia, xya daim tshev tseem ceeb tshaj plaws:
- Kev ua haujlwm txias
- Teeb duab compatibility
- Kev tswj cov dej paug
- Kev tiv thaiv corrosion
- Cov ntaub ntawv ua raws cai
- Lub sijhawm tsim khoom
- Shipping thiab them nqi nqe lus
Kev lees paub cov khoom no ua ntej kev tsim khoom feem ntau pheej yig dua li kev kho lub tshuab ua tiav.
1. Yuav Txias Performance, Tsis yog Radiator Loj
Thawj lo lus nug yuav tsum tsis yog, "Peb xav tau pes tsawg lub tshuab hluav taws xob?"
Lo lus nug tiag tiag yog:Lub tshuab hluav taws xob yuav tsum muaj cua sov ntau npaum li cas nyob rau hauv txoj haujlwm kev ua haujlwm?
Tus neeg muag khoom yuav tsum tau txais:
- Transformer poob
- ONAN lossis ONAF cua txias txoj kev
- Qhov siab tshaj plaws ambient kub
- Tso cai sab saum toj - roj kub nce
- Transformer roj hom
- Radiator mounting kev npaj
- Ntuj lossis yuam- huab cua yuav tsum
IEC 60076-2 txhais qhov kub thiab txias- qhov yuav tsum tau ua kom nce siab thiab ntsuas txoj hauv kev rau cov kua-immersed transformers.
Qhov no yog ib qho tseem ceeb nyob rau sab hnub tuaj Asia, qhov chaw kub ambient kub, av noo thiab txwv tsis pub huab cua tuaj yeem txo qhov kev nyab xeeb ntawm kev tsim cua txias tsis zoo.
Ib tug txhim khu kev qhafais fab transformer radiatoryuav tsum tau xaiv los ua ib feem ntawm qhov ua tiav transformer txias system, tsis yog ib qho kev sib cais steel.
2. Txias lub interface kos duab ua ntej ntau lawm
Lub tshuab hluav taws xob uas muaj vuam zoo heev tseem tsim kev rov ua haujlwm yog tias nws tsis tuaj yeem txuas rau lub tank transformer.
Ua ntej pom zoo rau daim duab, kos:
- Header center-rau-centre nrug
- Inlet thiab qhov hluav taws xob flange qhov ntev
- Bolt- qhov chaw
- Flange thickness thiab sealing ntsej muag
- Lub taub hau -pipe diameter
- Qhov cua thiab ntws tawm - qhov chaw ntsaws
- Ntxuam-frame thiab kev txhawb nqa brackets
- Tag nrho qhov ntev thiab qhov hnyav
IEC 60076-22-2: 2019 npog cov radiators tshem tau rau cov kua-immersed transformers, suav nrog kev sib hloov, kev pabcuam thiab cov kev xav tau kuaj.
Daim ntawv xaj yuav tsum tseem hais tias seb daim duab pom zoo, cov neeg siv khoom tshwj xeeb lossis tus qauv thoob ntiaj teb yuav tsum muaj qhov tseem ceeb yog tias xav tau tsis sib haum.
Txuas lub radiator teeb duab nrog lub transformer roj tank interface thaum ntxov tiv thaiv drilling, txiav los yog flange hloov kho thaum lub sij hawm kawg los ua ke.
3. Ua kom ntsuas qhov ntsuas qhov dej
Cov roj me me tuaj yeem nres kev sib dhos, ua rau cov txheej txheem ua kom puas thiab ncua FAT.
Qhov siab tshaj plaws - tej thaj chaw muaj kev pheej hmoo feem ntau suav nrog cov seams, lub ntsiab lus - mus rau -header welds, flange welds, header kawg daim hlau thiab qhov cua los yog qhov sib txuas.
Tsis txhob txais "100% kuaj" yam tsis muaj cov ntsiab lus. Nug:
- Qhov kev sim siab yog siv li cas?
- Nws khaws cia ntev npaum li cas?
- Puas yog txhua tus radiator kuaj?
- Puas yog lub ntsuas ntsuas ntsuas ntsuas?
- Puas yog lub tshuab hluav taws xob submerged hauv lub pas dej sim?
- Puas yog kho qhov chaw kuaj dua?
- Puas yog kev sim ua tiav ua ntej pleev xim?
Piv txwv li, kev tsim khoom yuav xav tau150 kPa rau 20 feeb, ua raws li kev soj ntsuam immersion. Kev khiav tawm npuas qhia txog qhov tsis xws luag uas yuav tsum tau kho thiab rov kuaj dua ua ntej kev kho deg.
Kev vam meejtransformer radiator manufacturersyuav tsum muab batch-linked test records es tsis yog tsuas txuas ib daim ntawv lo "dhau" xwb.
4. Muab cov txheej txheej rau qhov chaw tiag
Southeast Asia tsis yog ib puag ncig corrosion.
Ib txoj haujlwm hauv av hauv Thaib teb, thaj chaw muaj kev lag luam hauv Malaysia thiab chaw nres tsheb hauv ntug dej hiav txwv hauv Nyab Laj lossis Indonesia yuav xav tau kev tiv thaiv sib txawv.
Tus neeg yuav khoom yuav tsum qhia meej:
- Kev deb ntawm ntug dej hiav txwv
- Humidity thiab nag
- Ntsev lossis muaj kuab lom
- Yuav tsum tau kev pab lub neej
- Nto- qib kev npaj
- Tag nrho qhuav - zaj duab xis thickness
- Xim thiab UV tsis kam
TS EN ISO 12944-2 cais cov chaw muaj corrosive, thaum ISO 12944-5 txhawb kev xaiv xim.
Nyob ntawm qhov chaw, lub tshuab hluav taws xob yuav xav tau C3, C4 lossis C5 tiv thaiv. Kub-dip galvanizing lossis duplex system kuj tuaj yeem txiav txim siab qhov twg cov neeg siv khoom tshwj xeeb thiab cov qauv hluav taws xob tso cai rau nws.
Tshuaj xyuas tag nrho transformer radiator txheej txheej es tsis txhob pom zoo cov xim los ntawm cov xim los yog ntsev -tej teev ib leeg.
5. Cov ntaub ntawv Radiator cais los ntawm Transformer pom zoo
Cov chaw tsim khoom radiator thiab cov chaw tsim khoom siv hluav taws xob muaj cov luag haujlwm sib txawv.
Tus neeg muag khoom radiator yuav tsum tau muab:
- Pom zoo tsim cov duab kos
- Cov ntaub ntawv pov thawj
- Daim ntawv qhia qhov ntev
- Cov ntaub ntawv ntsuas kev ntsuas siab thiab cov dej xau
- Txheej tshuaj xyuas daim ntawv qhia
- Qhuav- zaj duab xis- nyeem ntawv tuab
- Ntim cov duab
Lub chaw tsim khoom ntawm transformer tseem yog lub luag haujlwm rau kev txheeb xyuas qhov kev ua haujlwm thermal ntawm qhov ua tiav transformer.
Rau kev quab yuam- cua txias, IEC 60076-22-6 npog cov kiv cua hluav taws xob siv nyob rau hauv transformer txias circuits.
Cov neeg yuav khoom yuav tsum tau tshawb xyuas qhov kev xav tau tshiab tshaj plaws los ntawm EVN hauv Nyab Laj, PLN hauv Indonesia, TNB hauv Malaysia lossis PEA thiab MEA hauv Thaib teb. Tsis txhob xav tias ib pob ntawv txaus siab rau txhua qhov khoom siv hluav taws xob lossis EPC tus neeg cog lus.
6. Ntsuas Lub Sijhawm Lead los ntawm Daim Ntawv Pom Zoo
Kev cog lus xa khoom tsis meej tshwj tsis yog nws qhov chaw pib tau txhais.
Kev tsim khoom yuav tsum pib tsuas yog tom qab lub flange kos duab, txheej txheej txheej txheem, kev soj ntsuam cov txheej txheem thiab kev soj ntsuam yuav tsum tau pom zoo.
Rau cov qauv radiator tej yaam num, ntau lawm yuav siv sij hawm ib ncig8-10 hnub, nyob ntawm seb muaj pes tsawg, tsim complexity, txheej thiab Hoobkas loading.
Lub sij hawm yuav tsum muaj xws li:
- Daim duab tshuaj xyuas
- Vuam thiab kuaj
- Kev kho saum npoo
- Kev soj ntsuam zaum kawg
- Export packing
- nkoj booking
Rau cov phiaj xwm hloov pauv sai, cov khoom xa tawm theem tuaj yeem tiv thaiv lub sijhawm sib dhos zoo dua li tos rau tag nrho cov kev txiav txim.
7. Npaj shipping thiab them nyiaj ua ntej ntim
Transformer radiators nyob hauv ntau qhov chaw ntim piv nrog lawv qhov hnyav.
IbFCL kev xa khoomfeem ntau txo qhov kev pheej hmoo. LCL tej zaum yuav haum me me lossis ceev kom muaj nuj nqis, tab sis kev hloov pauv ntxiv ua rau muaj feem cuam tshuam ntawm cov khoom khoov, txheej puas thiab cuam tshuam flanges.
Cov rooj vag muaj xws li Hai Phong lossis Cat Lai, Port Klang, Laem Chabang thiab Tanjung Priok.
Export packing yuav tsum muaj xws li:
- Rigid txhawb ncej
- Tiv thaiv flange ntsej muag
- Spacers ntawm lub tsev txhab nyiaj radiator
- Moisture barriers thiab desiccants
