Muaj pes tsawg leeg thiab Cov Khoom Profile ntawm C61400
C61400 yog wrought aluminium bronze ntawm Cu-Al-Fe system, feem ntau sau ua CuAl7Fe3. Cov ntsiab lus ntawm txhuas ua lub hauv paus ntawm cov alloy qhov corrosion kuj thiab lub zog, thaum cov hlau ntxiv refines lub grain qauv thiab tsa tsis kam hnav thiab cavitation puas. Nws yog muab raws li ASTM B150 rau pas nrig thiab bar, nyob rau hauv ASTM B171 rau phaj, ntawv thiab sawb, thiab kuj yog ua raws li raj thiab nyob rau hauv kev cai profiles.
| Element | Kev xav tau,% |
|---|---|
| Cu | Tseem tshuav, feem ntau txog 88 |
| Al | 6.0 - 8.0 |
| Fe | 1.5 - 3.5 |
| Mn | 1.0 max |
| Ni | 1.0 max |
| Zn | 1.0 max |
Cov kev txwv no ua raws li ASTM B150 thiab B171 cov kev cai rau qib. Aluminium ntau yam yog txhob txwm nqaim nqaim: hauv qab li ntawm 6% kev tiv thaiv aluminium oxide zaj duab xis yuav tsis ruaj khov, thiab siab dua 8% cov alloy hloov zuj zus thiab ua haujlwm tsawg dua nyob rau hauv cov xwm txheej wrought. Nyob rau hauv lub qhov rais specification cov khoom sib txuas ib tug tensile lub zog uas yog roughly ob zaug ntawm cov lag luam ntshiab tooj liab nrog ductility txaus rau kub sib sau thiab tiav machining.
Qhov no Alloy tiag khwv tau nws qhov chaw
Nws yog ib qho tsim nyog yuav tsum tau hais meej txog cov cuab yeej sib xyaw, vim tias txhuas bronze qee zaum tau piav qhia zoo li nws yog siab - tooj liab conductivity. Nws tsis yog. Nyob rau International Annealed Copper Standard, nyob rau hauv uas cov ntaub ntawv siv annealed tooj liab qauv yog txhais raws li 100% IACS, ib tug siab -conductivity busbar qib xws li C11000 mus txog 100 mus rau 101% IACS, thaum C61400 zaum roughly ib qho kev txiav txim ntawm magnitude qis. Cov hlau tsis raug xaiv los nqa cov kev lag luam tam sim no nyob rau qhov ntev.
Dab tsi C61400 muab es tsis txhob yog txhua yam thiab ib puag ncig kev ua tau zoo uas cov tooj liab ntshiab tsis tuaj yeem phim:
Lub zog thiab hardness:ob peb lub sij hawm lub zog thiab hardness ntawm annealed tooj liab, yog li ib tug tivthaiv muaj peev xwm nqa mechanical load, tiv thaiv deformation thiab tuav ib tug xov los yog ib tug machined feature.
Hnav thiab galling kuj:cov hlau- cov theem nplua nuj muab tus cwj pwm zoo hauv kev zawv zawg thiab kev sib cuag, qhov twg tooj liab ntshiab yuav khaws thiab txeeb.
Cavitation thiab erosion kuj:muaj nuj nqis nyob rau hauv lub twj tso kua mis impellers, valve trim thiab cheeb tsam ntawm turbulent flow.
Seawater thiab chloride kuj:zoo dua li feem ntau lwm cov wrought tooj liab alloys thiab deb zoo dua li cov tooj dag dawb, uas ua rau cov alloy haum rau cov ntug dej hiav txwv thiab sab nrauv.
Tsis yog-kev coj tus cwj pwm sib nqus thiab ua kom tsis muaj zog:muaj feem xyuam rau cov khoom siv nyob ze switchgear thiab rau cov cuab yeej uas ferrous qhov chaw raug txwv.
Cheebtsam nyob rau hauv Fais fab kis thiab Distribution Systems
Hauv kev sib txuas hluav taws xob, cov hlau alloy tau pom nyob qhov twg tam sim no - nqa cov khoom siv yuav tsum muaj sia nyob ntawm cov khoom siv hluav taws xob thiab kev ntxhov siab es tsis yog qhov tsawg tshaj plaws tus neeg xyuas pib hla - ntu tseem ceeb:
Switchgear thiab disconnector qhov chaw:tam sim no- nqa caj npab, pob khawm, ncej thiab tus pins uas yuav tsum tau muab cov hluav taws xob sib txuas nrog cov tshuab ua haujlwm ntev.
Tsheb thauj mus los kho vajtse thiab clamps:fittings uas clamp conductors tsis muaj galling, tuav lawv cov duab nyob rau hauv thermal cycling thiab tiv taus huab cua.
Hu rau blocks thiab terminal hardware:qhov chaw uas muaj kev rov ua dua ua - thiab - tawg ua haujlwm thiab hnav khaub ncaws.
Transformer thiab coj mus rhaub -Changer Cheebtsam:hnav-cov kabmob tiv taus, cov pas nrig thiab cov khoom siv hauv cov roj- cov khoom siv puv.
Earthing thiab grounding hardware:connectors, rods thiab clamps rau substation thiab ntauwd earthing, qhov twg av thiab atmospheric corrosion dominate.
Fais fab nroj tsuag auxiliary khoom:valve stems, rooj zaum, twj tso kua mis Cheebtsam thiab tshav kub exchanger qhov chaw raug rau cov dej txias.
Fabrication, Koom nrog thiab Mechanical Guidance
C61400 tau yooj yim machined nrog carbide tooling, thiab nws cov machinability txhim kho nyob rau hauv lub zog tempers. Kub ua hauj lwm yog nqa tawm nyob rau hauv ib tug kub qhov chaw uas lub alloy tseem ductile, nrog rau kev ua hauj lwm tiav los ntawm ib tug tsim nyog kho cua sov; kev sib sau txias yog txwv vim tias cov hlau ua haujlwm- hardens sai, yog li yuav tsum zam kom tsis txhob hnyav hnyav. Annealing restores ductility tab sis kuj txo lub zog, yog li qhov kev ua haujlwm kawg yuav tsum tau ua raws li qhov xav tau ntawm qhov ua tiav.
Kev sib koom ua ke yog ib txwm los ntawm kev sib tsoo, soldering nrog kev txhoj puab heev, lossis los ntawm kev siv tshuab fastening. Fusion welding yog ua tau tab sis xav kom ceev faj tswj: cov txhuas- nplua nuj oxide yog refractory, cov hlau ua cua sov tawm ntawm lub pas dej ua ke sai sai, thiab cov hlau- cov kabmob tuaj yeem hloov pauv los ntawm lub voj voog thermal. Qhov twg vuam tsis tuaj yeem zam tau, tsim nyog rau cov txheej txheem ntawm qhov tseeb ntu tuab thiab paub meej tias qhov sib koom ua ke khaws lub zog txaus thiab tiv thaiv corrosion.
Ob lub ntsiab lus tsim nyog tau txais kev saib xyuas vim tias lawv ua rau feem ntau ntawm kev ua tsis tiav. Thawj yog galvanic coupling: koom nrog txhuas bronze ncaj qha mus rau txhuas conductors los yog rau ib tug tsawg noble hlau tsim ib tug corrosion cell ntawm lub interface. Bimetallic connectors, tsim nyog nto thiab, nyob rau hauv faus kev pab cuam, ib tug haum qhwv los yog txheej tiv thaiv nws. Qhov thib ob yog kev sib cuag siab: bolts nyob rau hauv tam sim no - nqa cov pob qij txha yuav tsum tau nruj rau lub torque uas tau teev tseg, vim tias qhov siab me me ua rau muaj kev sib cuag thiab ua kom sov, thaum ntau dhau deforms lub hardware.
Xaiv thiab soj ntsuam cov ntsiab lus
Kev txiav txim tawm tsam UNS tus lej ntxiv rau qhov yuav tsum tau npau taws thiab cov khoom lag luam, vim tias cov khoom siv kho tshuab nyob ntawm kev kub ntxhov ntau dua li ntawm chemistry nyob rau hauv lub qhov rais specification.
Txheeb xyuas cov ntsiab lus ntawm aluminium thiab hlau los ntawm kev txheeb xyuas. Tawm - cov khoom siv tshuaj ntsuam xyuas tseem yuav zoo tab sis yuav tsis tsim cov oxide zaj duab xis los yog hardness.
Paub meej tias lub hardness thiab tensile zog ntawm ib tug qauv los ntawm tib lub tshav kub, tshwj xeeb tshaj yog nyob rau hauv qhov chaw yog load bearing.
Xyuas machined nto rau porosity, laps thiab inclusions, uas nyob rau hauv ib tug ntub ib puag ncig ua pitting pib qhov chaw.
Qhov twg cov khoom nqa tam sim no, paub meej tias nto tiav thiab flatness ntawm lub ntsej muag sib cuag, vim kev tiv thaiv kev tiv thaiv nyob ntawm qhov zoo ntawm qhov tsis zoo ntawm cov khoom siv ib leeg.
FAQ
Q: Puas yog C61400 yog siab -copper conductivity?
Tsis yog. Aluminium bronze muaj cov khoom siv hluav taws xob tsawg, kwv yees li qhov kev txiav txim ntawm qhov loj hauv qab 100% IACS kev siv ua tiav los ntawm siab -conductivity busbar tooj liab. Nws raug xaiv rau lub zog, hnav tsis kam thiab corrosion kuj nyob rau hauv tam sim no - nqa cov khoom siv, tsis yog kom txo qis tus neeg xyuas pib.
Q: Dab tsi yog qhov muaj pes tsawg leeg ntawm C61400?
Nws yog Cu-Al-Fe aluminium bronze nrog kwv yees li 6.0 txog 8.0% txhuas thiab 1.5 txog 3.5% hlau, nrog manganese, npib tsib xee thiab zinc txhua qhov txwv rau 1.0% siab tshaj plaws, thiab tooj liab raws li qhov sib npaug, ua raws li cov kev txwv ntawm ASTM B150 thiab B171.
Q: Vim li cas C61400 siv nyob rau hauv switchgear thiab substation hardware?
Vim tias cov khoom no yuav tsum nqa tam sim no thaum tseem tiv thaiv kev hnav, huab cua thiab chloride nres. Cheebtsam xws li clamp daim hlau, hu rau blocks thiab earthing hardware xav tau lub zog thiab galling kuj ntxiv rau suab hluav taws xob hu.
Q: C61400 puas tuaj yeem welded?
Nws tuaj yeem ua tau welded, tab sis cov txheej txheem xav tau vim yog lub refractory aluminium oxide zaj duab xis thiab cov cua kub ceev ntawm cov hlau. Brazing thiab mechanical fastening feem ntau yog nyiam; qhov twg welding yuav tsum tau, tsim nyog tus txheej txheem thiab xyuas cov khoom ntawm qhov sib koom ua ke.
Q: C61400 coj tus cwj pwm li cas hauv dej hiav txwv?
Zoo, muab cov xwm txheej ntws thiab dej chemistry tsim nyog. Cov hlau yog siv rau lub twj tso kua mis, valve thiab cov khoom siv hluav taws xob sib pauv hauv cov nroj tsuag marine thiab ntug dej hiav txwv. Raws li nrog rau lwm cov tooj liab alloys, cov xwm txheej tsis zoo, sulphide - bearing dej thiab tshaj tshaj tawm tuaj yeem txo qis kev ua haujlwm.
Q: Daim ntawv twg thiab qhov kub yuav tsum tau txiav txim?
Qws thiab bar rau ASTM B150 thiab phaj rau ASTM B171 yog cov ntaub ntawv wrought ntau, nrog rau kev npau taws xaiv rau qhov xav tau lub zog tiav. Qhia meej rau cov khoom siv, npau taws, qhov ntev thiab cov nyiaj siv ua haujlwm kom cov kev kho cua sov zaum kawg lossis ua haujlwm txias tawm hauv qhov raug.
