Bite ho ingaruka zo gusudira ya vacuum brazing itanura

Uburyo bwo gushakisha 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, ubushyuhe bwo hejuru cyane, ibishishwa byangiritse hamwe nubutaka.Igice gifatanye kirasa kandi kiroroshye, 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 bwitanura burashobora gushyukwa na gaze karemano cyangwa gushyushya amashanyarazi, kandi birashobora gushushanywa mumatanura yometse kuruhande, itanura ryubatswe munsi cyangwa itanura ryashyizwe hejuru (ubwoko bwa Kang).Sisitemu ya vacuum irashobora gukoreshwa muri rusange.

Sisitemu ya Vacuum ikubiyemo ahanini vacuum, umuyoboro wa vacuum, valve vacuum, nibindi. Igice cya Vacuum mubusanzwe kigizwe na rotary vane yamashanyarazi na pompe ikwirakwiza amavuta.Imashini ya mashini yonyine irashobora kubona munsi ya 1.35 degree Urwego rwa Vacuum rwa 10-1pa.Kugirango ubone icyuho kinini, pompe yo gukwirakwiza amavuta igomba gukoreshwa icyarimwe.Muri iki gihe, irashobora kugera kuri 1.35 degree Urwego rwa Vacuum rwa 10-4Pa.Umuvuduko wa gaze muri sisitemu upimwa hamwe na vacuum.

Gucana mu itanura rya vacuum ni ugukongeza mu itanura cyangwa mucyumba cyogeramo umwuka ukuramo umwuka.Irakwiriye cyane cyane gusya ingingo nini kandi zikomeza, kandi ikwiriye no guhuza ibyuma bimwe na bimwe bidasanzwe, nka titanium, zirconium, niobium, molybdenum na tantalum.Ifite intera nini ya porogaramu.Ariko, vacuum brazing nayo ifite ibibi bikurikira:

Metal Icyuma cyoroshye guhindagurika munsi ya vacuum, ntabwo rero gikwiye gukoresha vacuum brazing kumyuma fatizo nicyuma cyuzuza ibintu bihindagurika.Niba ari ngombwa gukoresha, ingamba zifatika zijyanye ningamba zizafatwa.

Azing Gukata Vacuum byunvikana hejuru yubuso, ubwiza bwinteko hamwe no kwihanganira ibice byasenyutse, kandi bisaba urwego rwo hejuru rwibikorwa byabakozi ndetse nababikora.

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, gusudira gusudira bigomba gushyirwa mu itanura (cyangwa mu cyombo gikonjesha), urugi rw'itanura rugafungwa (cyangwa igipfundikizo cy'ubwato bufunga), kandi kibanzirizwa mbere mbere. gushyushya.Banza utangire pompe ya mashini, 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, wishingikirize kuri pompe ya mashini na ikwirakwizwa rya pompe kugirango ikore mugihe gito, pompa itanura ryaka kurwego rusabwa, hanyuma utangire ingufu mubushuhe.

Mugihe cyose cyubushyuhe bwo kuzamuka no gushyuha, igice cya vacuum kizakomeza gukora kugirango kigumane urugero rwa vacuum mu itanura, guhagarika umwuka uva mumasoko atandukanye ya sisitemu ya vacuum hamwe nitanura ryaka, kurekura gaze hamwe nicyuka cyamamaza kuri Urukuta rw'itanura, guhuza no gusudira, guhindagurika kw'ibyuma na oxyde, n'ibindi, kugirango bigabanye umwuka wukuri.Hariho ubwoko bubiri bwa vacuum brazing: hejuru ya vacuum brazing 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 icyuma cyuzuza gihindagurika 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 gukingura bizafasha kubona ibisubizo byiza muri brazing vacuum.
