Chiyambi cha njira yopangira zinthu za RFMISO—kupangira vacuum brazing

1. Mfundo yaikulu:

Kuphimba kwa vacuum kumagwiritsa ntchito mphamvu yotentha kutentha solder mpaka pamene ikusungunuka ndikuphimba pamwamba pa zigawo zachitsulo zomwe zikuyenera kulumikizidwa. Mu malo otseguka, solder yotenthedwa imasungunuka ndikulowa m'malo olumikizirana a zigawo zachitsulo. Pamene kutentha kumachepa, solder imalimba ndikupanga kulumikizana kwamphamvu. Malo otseguka amathandiza kuchepetsa kupezeka kwa mpweya ndi zinyalala zina, motero amapereka mawonekedwe abwino a brazing.

2. Zipangizo ndi njira:

Kuphimba kwa vacuum nthawi zambiri kumafuna kugwiritsa ntchito ng'anjo ya vacuum kapena zida zophimba vacuum kuti zipereke malo oyenera otenthetsera ndi vacuum. Ma uvuni a vacuum nthawi zambiri amakhala ndi zinthu monga zinthu zotenthetsera, zipinda za vacuum, mapampu a vacuum, ndi makina owongolera kutentha. Pochita vacuum brazing, zigawo zachitsulo zimatsukidwa kaye ndikukonzedwa, kenako zimapakidwa ndi chitsulo chodzaza brazing. Kenako, zigawozo zimayikidwa mu uvuni wa vacuum ndikutenthedwa kuti solder isungunuke ndikulowa m'malo olumikizirana. Pomaliza, kutentha kumatsika, solder imalimba ndipo kulumikizana kumapangidwa.

3. Wogulitsa:

Pakuyika vacuum brazing, kusankha chitsulo choyenera chodzaza ndikofunikira kwambiri kuti pakhale kulumikizana kwabwino. Kusankha solder kumadalira zinthu monga zipangizo zachitsulo zomwe ziyenera kulumikizidwa, zofunikira pakugwiritsa ntchito komanso kutentha kwa ntchito. Zosolder zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo siliva, golide, mkuwa, nickel ndi zina zotero. Solder nthawi zambiri imagwiritsidwa ntchito ngati ufa, riboni kapena chophimba.

4. Madera ogwiritsira ntchito:

Ukadaulo wa vacuum brazing umagwiritsidwa ntchito kwambiri m'magawo ambiri. Umagwiritsidwa ntchito kwambiri mu ndege, zida zamagetsi, zida zowunikira, machubu a vacuum, masensa, zida zachipatala ndi malo amphamvu. Vacuum brazing imalola kulumikizana kwamphamvu kwambiri, kolimba kwambiri komanso kodalirika kwambiri kutentha kwambiri komanso kupsinjika kochepa kwambiri, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito mapulogalamu omwe amafunikira kulumikizana kwapamwamba kwambiri.

5. Ubwino

Ukadaulo wa vacuum brazing uli ndi ubwino wotsatira:

- Kulumikizana Kwamphamvu Kwambiri: Kuphimba kwa vacuum kumathandiza kulumikizana kwachitsulo kolimba ndi mphamvu zambiri komanso kutseka.

- Kukonza kutentha kochepa: Kuphimba vacuum nthawi zambiri kumachitika kutentha kotsika kuposa njira zina zowotcherera, zomwe zimachepetsa chiopsezo cha kusintha kwa zinthu ndi madera omwe amakhudzidwa ndi kutentha.

- Ubwino wolumikizira: Malo osungira mpweya amathandiza kuchepetsa kupezeka kwa mpweya ndi zinyalala zina, zomwe zimapangitsa kuti brazing ikhale yabwino kwambiri.

Kawirikawiri, ukadaulo wopangira vacuum brazing ndi njira yolumikizira yamphamvu kwambiri yomwe imalumikiza zitsulo pamodzi pamalo opanda vacuum. Imagwiritsidwa ntchito kwambiri m'mafakitale ambiri, kupereka kulumikizana kodalirika komanso mtundu wabwino kwambiri wolumikizira.
