Jiangsu HELIKE Fluid Technology Co., Ltd. ndi kampani yothandizirana ndi Dongxu Hydraulics.Ndi apadera pa kafukufuku ndi chitukuko, mapangidwe, kupanga ndi malonda a aluminiyamu plate-fin heat exchangers.
Njira ya Vacuum Aluminium Brazing
Tekinoloje ya vacuum aluminium brazing imagwiritsa ntchito aloyi ya aluminiyamu yokhala ndi malo otsika osungunuka kuposa aluminiyumu ngati chowotcha.Njirayi imatenthetsa zitsulo ndi solder pamwamba pa malo osungunuka a solder.Koma m'munsi kuposa kusungunuka kutentha kwa m'munsi zitsulo solder madzi amadzaza pang'ono kusiyana pakati pa workpieces awiri ndi kulowerera ndi diffuses ndi m'munsi zitsulo, potero kuzindikira njira kulumikiza workpieces kuti welded.
Ubwino waVacuumAaluminiumBkugwetsa
①Kutentha kwa kutentha kumakhala kochepa, kotero kuti thupi ndi mankhwala azitsulo zazitsulo sizidzakhudzidwa kapena kukhala ndi zotsatira zochepa.
② Ma welds masauzande ambiri amatha kuwotcherera nthawi imodzi.
③Kusinthika kwa magawowo ndikochepa, ndipo ndikosavuta kuwonetsetsa kukula kwa msonkhano.
④Kutentha m'malo opanda vacuum ndikopindulitsa kuchotsa filimu yamafuta ndi okusayidi pamwamba pa chogwirira ntchito, komanso kuwala kwapazigawo pambuyo kuwotcherera kumakhala kwakukulu.
⑤Palibe flux yofunika, palibe chifukwa chotsuka mutatha kuwotcherera.
⑥ Kuwotcha ndi kuzimitsa (kapena kutentha) kumatha kuchitika nthawi imodzi.
Makhalidwe ndi Zovuta za Aluminium Alloy Brazing Process
Chifukwa cha mawonekedwe apadera a aluminium alloy aloyi komanso mawonekedwe ake, zovuta zingapo ndi mawonekedwe zidzabuka panthawi yowotcha:
The mankhwala katundu wa aluminiyamu ndi yogwira, ndipo kuyanjana kwake ndi mpweya ndi wamphamvu kwambiri.Mumlengalenga kutentha kwa firiji, kuphatikiza kwa aluminiyamu ndi okosijeni kumapanga AL wandiweyani2O3filimu yokhala ndi makulidwe mpaka 0.1 μm.Kanema wa oxide ndi wandiweyani kwambiri, ndipo malo ake osungunuka ndi okwera mpaka 2050 ° C, kupitirira kwambiri kutentha kwa aluminium alloy.Panthawi imodzimodziyo, zidzalepheretsanso mgwirizano wabwino pakati pa zitsulo, ndipo mosavuta kupanga slag inclusions ndi pores.Choncho, chithandizo cha zitsulo zotayidwa chisanachitike komanso kupewa kapena kuchepetsa mapangidwe a filimu ya oxide mu kutentha ndikofunika kwambiri.Choncho, m'pofunika kwambiri kukhalabe mkulu vakuyumu mu ng'anjo, kuchepetsa mapangidwe filimu okusayidi kapena kuchotsa filimu okusayidi pa ndondomeko brazing, makamaka mu ndondomeko gawo la solder kusungunuka.
Kutentha kosungunuka kwa solder yopangidwa ndi aluminiyamu ndi 50-80 ° C kokha kusiyana ndi malo osungunuka a aluminiyamu yaikulu, ndipo malo ogwiritsira ntchito ndi ochepa.Choncho, m'pofunika kusankha mwanzeru kusankha solder ndi kudziwa kusungunuka kwa solder, ndipo panthawi imodzimodziyo, solder ndi zitsulo zoyambira ziyenera kukhala ndi madzi abwino.
Kusankhidwa koyenera kwa kutentha kwa brazing ndi nthawi yogwira ndikofunikira kwambiri kuti mupange mgwirizano wabwino wa brazed ndikuwonjezera mphamvu ya mgwirizano.
Kulondola kwapang'onopang'ono kwa zigawo za brazing ndikwapamwamba: mwachitsanzo, kulolerana kwapakati pakukonza zipsepse kumayendetsedwa pa ± 0.03mm malinga ndi zomwe takumana nazo, komanso mawonekedwe a msonkhano / kuvomerezeka kuyeneranso kuyang'aniridwa mosamalitsa.
