Chitofu cha vacuum ndi chipangizo chotenthetsera pansi pa vacuum, chomwe chimatha kutentha mitundu yambiri ya zinthu zogwirira ntchito, koma ogwiritsa ntchito ambiri sakudziwa zambiri za icho, sadziwa cholinga chake ndi ntchito yake, ndipo sadziwa chomwe chimagwiritsidwa ntchito. Tiyeni tiphunzire kuchokera ku ntchito yake pansipa.
Zitsulo zotsukira mpweya zimagwiritsidwa ntchito makamaka pochiza kutentha kwa chitsulo, kuyatsa ceramic, kusungunula vacuum, kuchotsa gasi ndi kuyika zinthu zamagetsi zotsukira mpweya, kuphimba zitsulo, ndi kutseka zitsulo za ceramic.
Ntchito:
1. Chotsukira cha vacuum chingagwiritsidwe ntchito pozimitsa vacuum (kutenthetsa, kuphimba), yomwe ndi njira yothandizira kukwaniritsa magwiridwe antchito omwe amayembekezeredwa mwa kutentha ndi kuziziritsa zipangizo kapena zigawo mu vacuum motsatira malamulo a ndondomekoyi. Kuphatikiza kuzimitsa gasi ndi kuzimitsa mafuta, ubwino wake ndi wakuti imatha kuteteza chitsulo ku okosijeni pansi pa vacuum, ndikupeza mphamvu yabwino yozimitsa kapena kuziziritsa nthawi yomweyo.
2. Kuthira vacuum brazing ndi njira yothira ma weldment pomwe gulu la ma weldment limatenthedwa kufika kutentha pamwamba pa malo osungunuka a chitsulo chodzaza koma pansi pa malo osungunuka a chitsulo choyambira mu mkhalidwe wa vacuum state, ndipo ma weld amapangidwa mwa kunyowetsa ndi kuyendetsa chitsulo choyambira pogwiritsa ntchito chitsulo chodzaza (kutentha kwa brazing kumasiyana malinga ndi zipangizo zosiyanasiyana).
3. Chotsukira cha vacuum chingagwiritsidwe ntchito pochotsa vacuum, kutanthauza njira yotenthetsera zinthu za ufa wachitsulo pansi pa vacuum kuti ufa wachitsulo woyandikana nawo upse upse m'zigawo zina kudzera mu kumatira ndi kufalikira.
4. Kuyika maginito mu vacuum kumagwiritsidwa ntchito makamaka pa kuyika maginito mu zipangizo zachitsulo.
Zitofu zotsukira mpweya zili ndi mitundu yosiyanasiyana, ndipo zimasiyana malinga ndi kukula kwa malo, kunyamula ng'anjo, mphamvu yotenthetsera, ndi zina zotero, kotero zitha kugwiritsidwa ntchito m'magawo omwe ali ndi zofunikira zosiyanasiyana pazinthu izi.
