Chiyambi cha njira yopangira RFMISO-vacuum brazing

1. Mfundo yofunika:

Vacuum brazing imagwiritsa ntchito mphamvu yotentha kuti itenthetse solder mpaka pamalo ake osungunuka ndikuyika pamwamba pazigawo zachitsulo kuti zilumikizidwe.M'malo opanda vacuum, solder yotentha imasungunuka ndikulowa m'malo olumikizana ndi zitsulo.Pamene kutentha kumachepa, solder imalimbitsa ndikupanga mgwirizano wamphamvu.Malo opanda vacuum amathandizira kuchepetsa kukhalapo kwa okosijeni ndi zonyansa zina, motero kumapereka mawonekedwe abwinoko.

2. Zida ndi njira:

Vacuum brazing nthawi zambiri imafuna kugwiritsa ntchito ng'anjo yopanda vacuum kapena zida za vacuum brazing kuti apereke malo oyenera kutentha ndi vacuum.Zida zounikira nthawi zambiri zimakhala ndi zinthu monga zotenthetsera, zipinda zotsekera, mapampu a vacuum, ndi makina owongolera kutentha.Mukamapanga vacuum brazing, zitsulo zimatsukidwa ndikukonzedwa, kenako zimakutidwa ndi zitsulo zodzaza ndi brazing.Kenaka, zigawozo zimayikidwa mu ng'anjo yowonongeka ndikutenthedwa kuti solder isungunuke ndikulowa pamalo okhudzana.Pomaliza, kutentha kumatsitsidwa, solder imalimbitsa ndipo kugwirizana kumapangidwa.

3. Solder:

Mu vacuum brazing, kusankha chitsulo choyenera cha filler ndikofunikira kuti mulumikizane bwino.Kusankhidwa kwa solder kumadalira zinthu monga zitsulo zomwe zimagwirizanitsidwa, zofunikira zogwiritsira ntchito komanso kutentha kwa ntchito.Ogulitsa wamba amaphatikizapo siliva, golide, mkuwa, nickel-based ndi ma alloys ena.Solder nthawi zambiri amagwiritsidwa ntchito ngati ufa, riboni kapena zokutira.

4. Malo ogwiritsira ntchito:

Tekinoloje ya vacuum brazing imagwiritsidwa ntchito kwambiri m'magawo ambiri.Amagwiritsidwa ntchito kwambiri muzamlengalenga, zida zamagetsi, zida zowonera, machubu a vacuum, masensa, zida zamankhwala ndi magawo amagetsi.Vuto la vacuum brazing limathandizira kulumikizidwa kwamphamvu kwambiri, kulimba kwambiri komanso kudalirika kwambiri pakutentha kwambiri komanso kutsika kwambiri, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafuna kulumikizana kwapamwamba.

5. Ubwino

Tekinoloje ya vacuum brazing ili ndi zabwino izi:

- Kulumikizana Kwamphamvu Kwambiri: Kupukuta kwa vacuum kumathandizira kulumikizana kwachitsulo kolimba ndi mphamvu yayikulu komanso kusindikiza.

- Kusintha kwa kutentha kwapansi: Kupukuta kwa vacuum kumachitika pa kutentha kochepa kusiyana ndi njira zina zowotcherera, kuchepetsa chiopsezo cha kuwonongeka kwa zinthu ndi madera omwe amakhudzidwa ndi kutentha.

- Kulumikizana kwabwino: Malo osungiramo vacuum amathandizira kuchepetsa kupezeka kwa okosijeni ndi zonyansa zina, kumapereka mawonekedwe abwinoko.

Nthawi zambiri, ukadaulo wa vacuum brazing ndi njira yolumikizira mwamphamvu kwambiri yomwe imalumikiza zida zachitsulo pamodzi pamalo opanda vacuum.Amagwiritsidwa ntchito kwambiri m'mafakitale ambiri, kupereka maulumikizidwe odalirika komanso khalidwe labwino kwambiri.
