C61400 Aluminium Bronze yog dab tsi
C61400 yog wrought txhuas bronze nyob rau hauv uas cov alloying ntxiv ntxiv dag zog rau cov tooj liab matrix thiab tsim ib tug tawv, nws tus kheej - rov qab nto zaj duab xis. Aluminium nyob ib ncig ntawm 7% muab cov alloy nws lub zog, hardness thiab tsis kam mus rau ntws dej; hlau refines cov nplej thiab txhim kho hnav tsis kam; nickel txhim kho corrosion kuj nyob rau hauv dej hiav txwv; thiab manganese pab deoxidation thiab pab txhawb zog.
| Lub ntsiab | Kev xav tau,% | Lub luag haujlwm |

Nws lub cev lub cev muaj feem cuam tshuam rau cov nroj tsuag dej tsim: qhov ntom ntom yog li 7.9 g / cm³, qhov sib txawv yog kwv yees li 1040-1055 degree, thermal conductivity yog nyob ib ncig ntawm 50 W / (m·K), thiab hluav taws xob conductivity qis dua li ntawm cov tooj liab tsis muaj hlau, ntawm kwv yees li 12. Cov kev xav tau ntawm cov khoom siv sib txawv nrog cov khoom tsim thiab kev kub ntxhov thiab tau teeb tsa hauv ASTM cov lus qhia tshwj xeeb rau tooj liab-alloy phaj, ntawv, bar thiab raj.
Vim li cas cov alloy kav ntev hauv cov cuab yeej kho dej
Kev pabcuam lub neej yog qhov tshwm sim ntawm ntau lub tshuab ua haujlwm ib zaug, thiab txhua tus coj txawv txawv hauv C61400.
General corrosion.Aluminium bronze tsim ib daim nyias nyias, adherent aluminium oxide zaj duab xis uas hloov kho sai sai thaum puas, yog li cov hlau tsis sib xws hauv cov dej kho yog feem ntau qeeb heev.
Erosion thiab cavitation.Cov hlau muaj kev tiv thaiv zoo rau qhov nrawm nrawm los ntawm qhov siab - dej nrawm, cov khoom nkag thiab tawg ua npuas npuas, uas yog vim li cas nws thiaj li siv rau lub twj tso kua mis impellers, hnav rings thiab valve trim. Txawm li cas los xij, cavitation tsis kam yog qhov kawg, thiab cavitation hnyav hauv lub twj tso kua mis tsis zoo yuav tseem ua rau qhov chaw puas tsuaj.
Scaling thiab deposition.Hard dej deposits scale ntawm wetted nto. Scale nws tus kheej tsis yog txhoj puab heev rau cov hlau, tab sis nws txo cov clearances, cuam tshuam ntws thiab muaj peev xwm nkaum cov crevices uas localized nres pib, yog li scale tswj yog ib feem ntawm lub neej extension.
Mechanical loading.Lub zog nruab nrab thiab zoo toughness tso cai rau lub alloy nqa lub cyclic loads ntawm rotating thiab reciprocating Cheebtsam yam tsis muaj qaug zog tawg, muab hais tias kev ntxhov siab concentration thiab misalignment yog tswj.
Hnav.Lub alloy resists zawv zawg thiab abrasive hnav zoo, ua rau nws haum rau bushes, bearings thiab qhia qhov twg dej nqa zoo xuab zeb los yog precipitate.
Kub.Kev pabcuam kub hauv kev kho dej yog me me, thiab cov hlau alloy lub zog thiab lub zog tseem nyob ruaj khov ntawm qhov ntau, suav nrog qis - qhov kub thiab txias hauv lub caij ntuj no.
Dej Chemistry thiab cov yam ntxwv ua haujlwm uas txiav txim siab kev pabcuam lub neej
| Qhov xwm txheej | Qhov cuam tshuam rau C61400 | Tswv yim tswj |
|---|---|---|
| Chlorides | Tau txais txiaj ntsig zoo ntawm cov dej ib txwm muaj- qib kho; cov yeeb yaj kiab tiv thaiv yog stabilized los ntawm txhuas | Saib xyuas cov tshuaj chloride thiab tswj cov kev ua haujlwm uas xav tau |
| pH | ruaj khov tiv thaiv zaj duab xis nyob rau hauv nruab nrab thiab me me alkaline dej; muaj zog acidic los yog muaj zog alkaline tej yam kev mob accelerate nres | Kev noj tshuaj kom raug thiab pH tswj cov khoom siv |
| Ammonia thiab ammonium compounds | Copper alloys feem ntau yog rhiab rau ammonia; cov nyhuv yuav tsum tau txiav txim siab qhov twg ammonium - tshuaj kho raws li tshuaj | Xaiv cov kev kho mob uas sib xws nrog cov tooj liab alloys |
| Dissolved oxygen thiab gases | Cov pa oxygen txaus txhawb kev tsim cov yeeb yaj kiab; ntau aeration ua ke nrog siab tshaj tawm tsub kom impingement nres | Deaeration qhov tsim nyog thiab zam kev nkag mus hauv huab cua |
| Suspended solids thiab xuab zeb | Ua rau abrasive hnav thiab yaig ntawm qhov chaw siab tshaj | Strainers, teeb tsa thiab tswj kev tshaj tawm |
| Chlorination thiab oxidizing biocides | Feem ntau txais tau ntawm tus nqi noj ib txwm; residual oxidant yuav tsum tsis txhob ntau dhau | Tswj residual concentration thiab tiv tauj lub sij hawm |
| Dissolved ntsev thiab scale qub | Txhawb kom tsim kev tso nyiaj ntau dua li kev tawm tsam ncaj qha | softening, tiv thaiv - nplai dosing thiab tu ncua sij hawm |
| Ceev thiab turbulence | Lub zog muaj zog tshaj plaws ntawm kev yaig lub neej ntawm li qub, khoov thiab impellers | Qhov loj ntawm cov kav dej thiab cov twj tso kua mis kom ceev cov nrawm hauv zos tsis pub dhau qhov kev txwv tsim |
| Galvanic coupling | Copper alloys yog cathodic rau hlau thiab txhuas; coupling accelerates nres ntawm cov hlau tsis tshua muaj suab npe | Insulating pob qij txha, coatings thiab raug cov ntaub ntawv pairing |
Yuav Ua Li Cas Ntxiv Kev Pabcuam Lub Neej Hauv Kev Xyaum
Vim tias ntau lub tshuab ua ke ua ke, lub neej txuas ntxiv yog qhov kev pab cuam ntau dua li cov khoom siv hloov pauv.
Saib xyuas cov dej zoo li niaj zaus, suav nrog pH, chloride, yaj cov pa oxygen, cov oxidant residual thiab tshem tawm cov khib nyiab, thiab sau cov txiaj ntsig tiv thaiv kev tiv thaiv.
Xaiv cov tshuaj kho mob uas sib haum nrog tooj liab alloys, tshwj xeeb tshaj yog qhov twg ammonium lossis cov tshuaj chelating muaj zog tau thov.
Khaws qhov chaw tsis muaj nplai nrog kev npaj tu uas tsis tau qhab nia lossis embed cov khoom txawv teb chaws; Abrasive txoj kev yuav tsum tau zam ntawm sealing ntsej muag.
Tshawb xyuas cov impellers, hnav lub nplhaib, rooj zaum thiab cov lus qhia ntawm lub sijhawm ruaj khov, thiab cov ntaub ntawv tshem tawm kom tsis txhob raug ntsuas ntau dua li qhov kwv yees.
Txheeb xyuas qhov sib npaug, sib npaug thiab kev coj tus kheej, vim tias kev ua haujlwm tsis zoo ua rau muaj kev ua tsis tiav ntxov hauv cov nroj tsuag dej ntau dua li kev xeb.
Tshawb xyuas kev sib raug zoo nrog cov ntaub ntawv uas nyob ib sab ntawm cov qauv tsim, thiab siv cov khoom siv insulating los yog txheej txheej uas cov hlau tsis sib xws tsis tuaj yeem zam tau.

FAQ
Q: Dab tsi yog qhov kev pab cuam lub neej ntawm C61400 txhuas bronze hauv cov khoom kho dej?
Tsis muaj ib daim duab. Nyob rau hauv cov dej tswj tau zoo nrog cov kev nrawm nrawm thiab kev npaj kho, cov khoom xws li cov twj tso kua mis thiab lub valve trim niaj hnub ncav cuag lawv lub neej tsim tag nrho; Nyob rau hauv cov dej txhoj puab heev, ntawm qhov nrawm nrawm, lossis nrog cov nplais tsis zoo thiab kev tswj tshuaj, lub neej luv dua. Cov kev txiav txim siab yog dej chemistry, tshaj tawm, qhov kub thiab txias thiab kev xyaum ua haujlwm.
Q: Puas yog C61400 tiv taus dej hiav txwv?
Yog lawm. Aluminium - nplua nuj nto zaj duab xis muab txhuas bronze zoo tiv thaiv dej hiav txwv thiab rau ntau yam acidic thiab alkaline daws, uas yog vim li cas cov alloy yog siv rau marine thiab offshore Cheebtsam nrog rau cov khoom kho dej.
Q: Puas yog C61400 tiv thaiv cavitation thiab yaig?
Nws tiv taus ob qho tib si zoo dua li tooj dag los yog tooj dag, thiab qhov no yog ib qho ntawm cov laj thawj uas nws raug xaiv rau impellers, hnav rings thiab valve internals. Qhov kev tiv thaiv yog qhov kawg, yog li cov kev tshaj tawm hauv zos thiab cov twj tso kua mis ua haujlwm yuav tsum tseem nyob hauv qhov txwv tsim.
Q: Dab tsi yog qhov hluav taws xob conductivity ntawm C61400?
Nws yog qhov qis dua li cov tooj liab ntshiab, ntawm kwv yees li 12% IACS. Aluminium nyob rau hauv cov khoom sib tov scatters conduction electrons, yog li lub alloy yuav tsum tsis txhob xaiv qhov twg high hluav taws xob los yog thermal conductivity yog tswj yuav tsum tau.
Q: Yam tshuaj kho dej twg yuav tsum zam?
Cov khoom uas aggressively ammoniacal los yog muaj zog chelating ntawm tooj liab tuaj yeem ua kom nrawm nrawm. Cov neeg ua haujlwm kho mob yuav tsum raug kuaj xyuas kom muaj kev sib raug zoo nrog cov tooj liab alloys ua ntej lawv nkag mus rau hauv lub kaw lus uas muaj C61400 Cheebtsam.
Q: C61400 puas tuaj yeem welded thiab kho?
Cov hlau muaj kev ua tau zoo thiab tuaj yeem nrum, forged, kub dov thiab txias kos. Nws cov weldability yog nruab nrab: kev kho yog ua tau nrog cov txheej txheem tsim nyog thiab muab tub lim hlau, tab sis cov khoom siv hluav taws xob yuav tsum tau tswj kom tsis txhob muaj kev hloov pauv ntawm cov khoom ntawm cov khoom nyob ib puag ncig. Brazing thiab mechanical fixing feem ntau yog siv los hloov.
