Nkag siab li cas PSA hauv Nitrogen Cog Tsav Kev Txhim Kho ntawm Aluminium Tuag Casting Kev Lag Luam

Hauv cov toj roob hauv pes ntawm kev lag luam niaj hnub no, kev lag luam aluminium tuag casting tsim suav tsis txheeb cov khoom tseem ceeb los ntawm nws cov txheej txheem -los ntawm qhov tseeb cav qhov chaw hauv tsheb mus rau cov khoom siv hluav taws xob zoo. Aluminium tuag castings yog ubiquitous, txhaj tshuaj muaj zog rau hauv kev loj hlob ntawm ntau yam lag luam. Txawm li cas los xij, tom qab qhov kev tsim khoom zoo li no, cov txheej txheem txhuas tuag casting ntsib ntau yam teeb meem. Qhov tshwm sim ntawmPSA Nitrogen Generatorsyog zoo li lub teeb ci, coj ib qho kev hloov pauv rau kev lag luam.

Qhov "Invisible Killers" ntawm Aluminium Tuag Casting Kev Lag Luam

Hydrogen thiab oxygen yog ob "cov neeg tua tsis pom" hauv cov txheej txheem tuag casting. Thaum molten aluminium yog rhuab ntawm qhov kub siab, nws yooj yim reacts nrog dej vapor nyob rau hauv cov huab cua, thiab ib tug loj npaum li cas ntawm hydrogen dissolves rau hauv lub molten txhuas. When the molten aluminum cools and solidifies, the solubility of hydrogen drops sharply, and the trapped hydrogen forms dense pores inside the casting. Cov pores no zoo li zais lub sijhawm foob pob hauv qhov casting, ua kom tsis muaj zog ntawm cov cuab yeej ntawm cov casting, txo nws lub zog thiab toughness. Qhov no ua rau cov khoom muaj kev pheej hmoo ntawm kev tawg thiab deformation hauv kev siv tom ntej, cuam tshuam rau cov khoom zoo, kev pabcuam lub neej, ua rau tus nqi tsis zoo, thiab nce nqi ntau lawm.

Lub caij no, muaj cov pa oxygen kuj yog ib qho kev txhawj xeeb loj. Thaum kub kub, molten aluminium reacts sai nrog oxygen, tsim ib txheej ntawmaluminium oxide zaj duab xisntawm nws qhov chaw. Cov yeeb yaj kiab no tsis yog tsuas yog ua kom cov viscosity ntawm cov molten aluminium, cuam tshuam nws cov dej ntws thiab sau rau hauv pwm (ua rau muaj qhov tsis xws luag xws li misruns thiab qhov tsis sib xws) tab sis kuj, yog tias aluminium oxide zaj duab xis raug kaw hauv qhov casting, nws dhau los ua impurity sab hauv- txo qis casting zoo thiab cuam tshuam cov khoom muag thiab kev ua haujlwm.

Lub luag haujlwm ntawmPSA Nitrogen Generatorshauv Aluminium Tuag Casting

Melting Rauv Purification thiab Purification

Thaum lub sij hawm txhuas melting, siab -purity nitrogen (tsim los ntawmPSA Nitrogen Generators) yog txhaj rau hauv cov molten aluminium ntawm cov khoom siv ntxeem tau. Raws li nitrogen npuas nce nyob rau hauv molten aluminium:

Ntawm ib sab, cov npuas ua raws li me me "cov tshuaj ntxuav" - adsorbing impurities thiab yaj cov roj nyob rau saum npoo ntawm molten aluminium, thiab txhawb cov tshuaj tiv thaiv ntawm refining agents thiab molten aluminium. Qhov no zoo tshem tawm impurities thiab teeb meem gases, txohydrogen poresthiab impurity tsis xws luag.

Ntawm qhov tod tes, txij li thaum pib lub siab ntawm nitrogen npuas yog 0 (deb qis dua ib nrab siab ntawm hydrogen nyob rau hauv molten aluminium), hydrogen nyob rau hauv lub molten aluminium yuav tsis diffuse rau hauv npuas. Hloov chaw, nws yog nqa tawm ntawm molten aluminium los ntawm cov npuas, ua kom tau txais txiaj ntsig hydrogen tshem tawm.

Cov txheej txheem no yuav tsum muaj nitrogen purity siab (feem ntau 99.9% - 99.99%), uas ua kom lub purity ntawm molten aluminium thiab nteg lub hauv paus ruaj khov rau tom ntej tuag casting.

Atmosphere tiv thaiv thaum tuag Casting

Thaum lub sij hawm tuag casting txheej txheem, nitrogen yog tsis tu ncua txhaj rau hauv pwm kab noj hniav thiab molten txhuas txaus channel, tsim ib tug inert cua uas cais oxygen. Qhov no "cov txheej txheem tiv thaiv":

• Tiv thaiv molten aluminium los ntawm kev sib cuag nrog oxygen, tsis txhob oxidation cov tshuaj tiv thaiv thiab tsim ntawm aluminium oxide zaj duab xis.
• Txo cov viscosity ntawm molten aluminium, tso cai rau nws ntws ntau smoothly hauv pwm.
• Qhov no ua kom lub casting tiav thiab muaj ib tug du nto, zoo heev txhim kho casting zoo thiab yield.

Cov cuab yeej ntxuav thiab tu

Hauv kev ua haujlwm txhua hnub thiab kev saib xyuas cov khoom siv txhuas tuag casting, nitrogen (los ntawmPSA Nitrogen Generators) yog siv rau kev purging ntawm melting furnaces, tuag casting tshuab, thiab lwm yam. Qhov no zoo tshem tawm cov residual khib nyiab, impurities, thiab cov kab mob nyob rau hauv cov khoom, kom nws huv si. Cov txiaj ntsig muaj xws li:

• Tiv thaiv impurity tsub zuj zuj uas cuam tshuam rau cov cuab yeej ua haujlwm thiab kev ruaj ntseg.
• Extending khoom siv lub neej.
• Txo downtime vim tsis ua hauj lwm, kom ntseeg tau ntau lawm continuity.

Cov txiaj ntsig tseem ceeb coj los ntawmPSA Nitrogen Generators

Zoo Leap

Siv lub tsheb loj aluminium alloy qhov tuag casting tuam txhab ua piv txwv:

Ua ntej yuavPSA Nitrogen Generators, nws cov khoom tsis raug tus nqi yog 15% (tsuas yog vim hydrogen pores thiab oxide impurities).

Tom qab qhia txog nitrogen huab cua tswj nyob rau hauv melting thiab tuag casting, tus nqi defect poob mus rau hauv qab 5%.

Cov khoom tseem ceeb uas tsim tawm (piv txwv li, lub tog raj kheej lub tog raj kheej lub cav) tau txhim kho qhov zoo ntawm sab hauv- kev tshuaj xyuas pom tau tias txo qis hauv qhov pores thiab impurities. Cov khoom lag luam tau txais kev lees paub zoo los ntawm cov kws tsim tsheb, tso cai rau lub lag luam nkag mus rau cov khoom siv ntawm ntau lub siab -kawg hom tsheb.

Tus nqi txo

Los ntawm qhov kev xav ntawm tus nqi,PSA Nitrogen Generatorsnqa mus ntev - txuag nyiaj. Siv cov khoom siv hluav taws xob aluminium alloy casing tuag casting:

Yav dhau los, lub raj mis nitrogen raug nqi 20 yuan / lub raj mis, nrog 3,000 lub raj mis noj txhua hli (tag nrho: 60,000 yuan / hli, tsis suav nrog cov nqi tsheb thauj mus los / khaws cia).

Tom qab hloov mus rau -site nitrogen tiam, tus nqi ib cubic meter ntawm nitrogen yog ~ 0.5 yuan. Nrog 6,000 m³ noj txhua hli, tus nqi poob rau 3,000 yuan / hli-a95% txonyob rau hauv cov nqi, zoo heev txhim kho profitability.

Kev txhim kho kev ua haujlwm

PSA Nitrogen Generatorsmuab cov nitrogen hauv lub sijhawm tiag tiag, tsis txhob muaj kev pheej hmoo ntawm cov fwj tshuaj / kua nitrogen. Piv txwv li:

Kev tuag casting pwm accessory Hoobkas yav tas los kaw 2-3 zaug / hli vim ncua kev xa khoom nitrogen (ua rau kev tsim khoom qeeb).

Tom qab sawsPSA Nitrogen Generators, txhua hli cov zis tau nce 20%, thiab kev txiav txim tus nqi xa tawm tau nce los ntawm 80% mus rau 98%, txhawb kev lag luam kev sib tw.

Yav tom ntej Trends ntawm Aluminium Tuag Casting Kev Lag Luam

Kev txawj ntse txawj tej yam ntxiv

Nyob rau yav tom ntej,PSA Nitrogen Generatorsyuav hloov mus rau kev txawj ntse:

Nruab nrog sensors thiab ntse tswj systems, lawv yuav tiag -lub sij hawm saib xyuas tsis (molten aluminium kub, nitrogen purity / ntws, thiab lwm yam).

Lawv yuav hloov kho cov haujlwm ua haujlwm kom ua tiav cov khoom siv nitrogen zoo, txhim kho kev ua haujlwm thiab cov khoom lag luam zoo.

Kev koom ua ke nrog Cov Txheej Txheem Tshiab

Raws li cov txheej txheem tshiab (semi-cov khoom tuag casting, lub tshuab nqus tsev tuag casting) nce traction,PSA Nitrogen Generatorsyuav integrate nrog lawv:

Hauv semi-cov khoom tuag casting: Nitrogen yuav do thiab tiv thaiv ib nrab- cov khoom siv, ua kom zoo dua qub rau kev siv loj - nplai.

Kev txuag hluav taws xob ntsuab

Tawm tsam keeb kwm ntawm lub ntiaj teb ntsuab kev loj hlob,PSA Nitrogen Generatorsyuav optimize technology:

• Txais lub zog-txuag compressors thiab cov adsorbents siab heev kom txo tau lub zog siv.
• Ua tiav nitrogen rov qab thiab rov siv dua, ua kom muaj peev txheej rov ua dua tshiab thaum txiav cov nqi thiab txhawb kev txhim kho kom ruaj khov.

PSA Nitrogen Generatorstau dhau los ua cov cuab yeej tseem ceeb rau kev lag luam txhuas tuag casting los txhim kho qhov zoo, txo cov nqi, thiab txhim kho kev ua haujlwm zoo. Nyob rau hauv lub neej yav tom ntej, lawv yuav txuas ntxiv innovate, sib koom ua ke tob rau hauv txhua qhov txuas ntawm kev lag luam kev loj hlob. Aluminium tuag casting tuam txhab yuav tsum tuav qhov kev hloov pauv no kom tau txais kev sib tw hauv kev sib tw thiab ua tiav kev loj hlob leapfrog.
