Jiangsu HELIKE Fluid Technology Co., Ltd. yog lub koom haum ua lag luam ntawm Dongxu HydraulicsNws yog tshwj xeeb hauv kev tshawb fawb thiab kev tsim kho, tsim, tsim khoom thiab muag khoom ntawm aluminium phaj-fin heat exchangers.
Mechanism ntawm Vacuum Aluminium Brazing
Nqus aluminium brazing tshuab siv aluminium alloy nrog qis melting point tshaj aluminium li cov khoom siv brazing.Cov txheej txheem no heats lub vuam thiab solder saum lub melting point ntawm solder.Tab sis qis dua qhov kub ntawm lub hauv paus hlau, cov kua nplaum ua rau qhov sib txawv me me ntawm ob lub workpieces los ntawm infiltration thiab diffuses nrog lub hauv paus hlau, yog li paub txog ib txoj kev ntawm kev sib txuas ntawm cov workpieces rau welded.
Qhov zoo ntawmVacuumAluminiumBrazing
① Cov cua kub kub qis, yog li lub cev thiab tshuaj lom neeg ntawm lub hauv paus hlau yuav tsis cuam tshuam los yog muaj kev cuam tshuam me ntsis.
② Ntau txhiab welds ntawm complex qhov chaw tuaj yeem welded ib zaug.
③ Lub deformation ntawm cov khoom me me, thiab nws yooj yim los xyuas kom meej qhov loj ntawm lub rooj sib txoos.
④ Cov cua kub hauv lub tshuab nqus tsev yog qhov zoo rau tshem tawm cov roj thiab oxide zaj duab xis rau ntawm qhov chaw ua haujlwm, thiab qhov ci ntsa iab ntawm qhov chaw tom qab vuam yog siab.
⑤ Tsis tas yuav tsum muaj dej ntws, tsis tas yuav ntxuav tom qab vuam.
⑥ Brazing thiab quenching (lossis qee qhov kev kho cua sov) tuaj yeem ua tiav tib lub sijhawm.
Cov yam ntxwv thiab qhov nyuaj ntawm Aluminium Alloy Brazing txheej txheem
Vim yog lub cev thiab tshuaj lom neeg tshwj xeeb ntawm aluminium alloy, cov teeb meem thiab cov yam ntxwv yuav tshwm sim thaum lub sij hawm brazing txheej txheem:
Cov khoom siv tshuaj lom neeg ntawm txhuas yog cov nquag nquag, thiab nws txoj kev sib raug zoo nrog cov pa oxygen muaj zog heev.Nyob rau hauv cov huab cua ntawm chav tsev kub, kev sib xyaw ua ke ntawm txhuas thiab oxygen yuav tsim ib qhov ntom ntom AL2O3zaj duab xis nrog lub thickness txog li 0.1 μm.Cov oxide zaj duab xis yog ntom heev, thiab nws cov ntsiab lus melting yog siab li 2050 ° C, deb tshaj qhov kub melting ntawm aluminium alloy.Nyob rau tib lub sijhawm, nws tseem yuav cuam tshuam kev sib raug zoo ntawm cov hlau, thiab yooj yim tsim cov slag suav nrog thiab qhov pores.Yog li ntawd, kev kho ua ntej vuam ntawm aluminium alloys thiab kev tiv thaiv los yog txo cov oxide zaj duab xis tsim nyob rau hauv lub rhuab lub xeev yog ib qho tseem ceeb heev.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum muaj lub tshuab nqus tsev siab hauv qhov cub, txo qhov tsim ntawm oxide zaj duab xis los yog tshem tawm cov oxide zaj duab xis thaum lub sij hawm brazing txheej txheem, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem ntawm solder melting.
Lub melting kub ntawm aluminium-raws li solder tsuas yog 50-80 ° C txawv ntawm lub melting point ntawm lub ntsiab aluminium alloy, thiab qhov chaw ua hauj lwm yog me me.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum xaiv cov solder kom tsim nyog thiab txiav txim siab qhov sib txawv ntawm cov solder, thiab tib lub sijhawm, cov hlau thiab lub hauv paus hlau yuav tsum muaj qhov zoo wettability.
Kev xaiv kom raug ntawm brazing kub thiab tuav lub sij hawm yog ib qho tseem ceeb heev los tsim ib tug zoo brazed sib koom thiab txhim kho lub zog ntawm kev sib koom tes.
Qhov tseeb qhov tseeb ntawm cov khoom siv brazing yog siab: piv txwv li, qhov ntev ntawm kev ua haujlwm ntawm fin yog tswj ntawm ± 0.03mm raws li peb qhov kev paub, thiab kev sib dhos zoo / kev tshem tawm yuav tsum tau tswj nruj me ntsis.
