Gucisha mu itanura rya vacuum nuburyo bushya bwo gushakisha butagira flux mubihe bya vacuum.Kuberako guswera biri mubidukikije, ingaruka mbi zumwuka kumurimo wakazi zirashobora kuvaho neza, bityo brazing irashobora gukorwa neza udakoresheje flux.Ikoreshwa cyane cyane mugukata ibyuma hamwe nuruvange bigoye kurigata, nka aluminiyumu, aluminiyumu, titanium, superalloy, ibinure byangiritse hamwe nubutaka.Igice gifatanye kirasa kandi cyinshi, hamwe nibikoresho byiza bya mashini hamwe no kurwanya ruswa.Ibikoresho byo kumena Vacuum mubusanzwe ntibikoreshwa mugusudira inshinge ibyuma bya karubone nicyuma gito.
Ibikoresho byo gusya mu itanura rya vacuum bigizwe ahanini nitanura rya vacuum na sisitemu ya vacuum.Hariho ubwoko bubiri bwa vacuum brazing Itanura: Amashyiga ashyushye hamwe numuriro ukonje.Ubwoko bubiri bw'itanura burashobora gushyukwa na gaze karemano cyangwa gushyushya amashanyarazi.Birashobora gushushanywa mu itanura ryubatswe ku ruhande, itanura ryashyizwe hejuru cyangwa itanura ryashyizwe hejuru (ubwoko bwa Kang), kandi sisitemu ya vacuum irashobora kuba rusange.
Sisitemu ya Vacuum ikubiyemo cyane cyane vacuum, umuyoboro wa vacuum, valve vacuum, nibindi. Igice cya vacuum mubusanzwe kigizwe na rotary vane yamashanyarazi na pompe ikwirakwiza amavuta.Gukoresha imashini imwe irashobora kubona munsi ya 1.35 degree Icyuho cya 10-1pa urwego.Kugirango ubone icyuho kinini, pompe yo gukwirakwiza amavuta igomba gukoreshwa icyarimwe, ishobora kugera kuri 1.35 muriki gihe degree Impamyabumenyi ya Vacuum ya 10-4Pa.Umuvuduko wa gaze muri sisitemu upimwa hamwe na vacuum.
Gucisha mu itanura rya vacuum ni ugukongeza mu itanura cyangwa mucyumba cyo gukuramo umwuka ukuramo umwuka.Birakwiriye cyane cyane gushakisha ingingo nini kandi zikomeza.Irakwiriye kandi guhuza ibyuma bimwe bidasanzwe, harimo titanium, zirconium, niobium, molybdenum na tantalum.Ariko, vacuum brazing nayo ifite ibibi bikurikira:
① Mubihe bya vacuum, ibyuma biroroshye guhindagurika, kubwibyo gushakisha vacuum ntibigomba gukoreshwa mubyuma fatizo no kugurisha gusudira ibintu bihindagurika.Nibiba ngombwa, ingamba zifatika zijyanye ningamba zigomba gufatwa.
Azing Gukata Vacuum byunvikana hejuru yubuso, ubwiza bwiteranirizo hamwe no kwihanganira ibice byasenyutse, kandi bifite ibisabwa byinshi mubidukikije ndetse nurwego rwabakozi.
Equipment Ibikoresho bya Vacuum biragoye, hamwe nishoramari rimwe rimwe nigiciro kinini cyo kubungabunga.
None, nigute washyira mubikorwa uburyo bwo gushakisha mu itanura rya vacuum?Iyo gukonjesha bikozwe mu itanura rya vacuum, shyira gusudira hamwe no gusudira mu itanura (cyangwa mu gikoresho cya brazing), funga umuryango w’itanura (cyangwa ufunge igifuniko cya kontineri), hanyuma ubanze ucyure mbere yo gushyushya.Tangira pompe ya mashini ubanza, hinduranya valve nyuma ya dogere ya vacuum igeze kuri 1.35pa, funga inzira itaziguye hagati ya pompe ya mashini nitanura ryaka, kora umuyoboro uhujwe nitanura ryaka ukoresheje pompe ikwirakwizwa, kora mugihe gito na wishingikirije kuri pompe ya mashini na pompe ya diffuzione, pompa itanura ryaka kurwego rusabwa, hanyuma utangire gushyushya amashanyarazi.
Mugihe cyose cyizamuka ryubushyuhe nubushyuhe, ishami rya vacuum rizakora ubudahwema kugirango hagumane urugero rwa vacuum mu itanura, kuzimya umwuka uva mumasoko atandukanye ya sisitemu ya vacuum hamwe nitanura ryaka, kurekura gaze numwuka wamazi wamamajwe nitanura. urukuta, imiterere no gusudira, hamwe no guhindagurika kwicyuma na oxyde, kugirango bigabanye umwuka wukuri.Hariho ubwoko bubiri bwa brazing ya vacuum: gushakisha hejuru ya vacuum hamwe na vacuum igice (vacuum yo hagati).Gukoresha vacuum nyinshi birakwiriye cyane gusya ibyuma fatizo oxyde igoye kubora (nka nikel base superalloy).Igice cya vacuum igice cyakoreshejwe mugihe icyuma fatizo cyangwa ugurisha bihindagurika munsi yubushyuhe bukabije hamwe nubushyuhe bukabije.
Mugihe hagomba gufatwa ingamba zidasanzwe kugirango habeho isuku nyinshi, uburyo bwo kweza vacuum bwakoreshwa mbere yo gukama hydrogène yumye.Mu buryo nk'ubwo, gukoresha hydrogène yumye cyangwa uburyo bwo kweza gazi mbere yo kuvoma vacuum bizafasha kubona ibisubizo byiza muri brazing vacuum.
