Ingaruka zo gusudira z'itanura rikoresha icyuma gifunga umwuka ni izihe?

Gushyira icyuma mu itanura ry'ibikoresho byo mu bwoko bwa "vacuum flavor" ni uburyo bushya bwo gushyira icyuma mu buryo budasanzwe hatabayeho flux mu gihe cy'ibikoresho byo mu bwoko bwa "vacuum flavor". Kubera ko icyuma gishyirwa mu buryo budafite flux, ingaruka mbi z'umwuka ku gikoresho cyo gukora zishobora gukurwaho neza, bityo icyuma gishyirwa mu buryo buboneye hatabayeho gukoresha flux. Gikoreshwa cyane cyane mu byuma byo gushyiramo icyuma n'ibindi bikoresho bigoye gushyiramo flux, nka aluminiyumu, titanium alloy, superalloy, refractory alloy na ceramics. Igice cyometseho icyuma kirabagirana kandi gifite ubunini, gifite imiterere myiza ya mekanike kandi kirwanya ingese. Ibikoresho byo gushyiramo icyuma mu buryo busanzwe ntibikoreshwa mu gusudira urushinge rw'icyuma cya karuboni n'icyuma gito.

Ibikoresho byo gushyushya mu itanura rikoresha umwuka ushyushye bigizwe ahanini n'itanura rikoresha umwuka ushyushye n'uburyo bwo gushyushya. Hari ubwoko bubiri bw'amatanura akoresha umwuka ushyushye: Amatanura ashyushye n'amatanura akonje. Ubwoko bubiri bw'amatanura bushobora gushyushywa na gaze karemano cyangwa ubushyuhe bw'amashanyarazi. Bishobora gushushanywa mu itanura rishyirwa ku ruhande, itanuru rishyizwe hasi cyangwa itanuru rishyizwe hejuru (ubwoko bwa Kang), kandi uburyo bwo gushyushya bushobora kuba rusange.

Sisitemu yo gusohora amavuta irimo ahanini icyuma gisohora amavuta, umuyoboro wa vacuum, valve ya vacuum, nibindi. Igice cy’icyuma gisohora amavuta gikunze kuba kigizwe na pompe ihindura imashini ikora vene na pompe ihindura amavuta. Pompe ikoreshwa rimwe ishobora kubona dogere iri munsi ya 1.35 × dogere ya vacuum ya 10-1pa. Kugira ngo pompe ihinduke cyane, pompe ihindura amavuta igomba gukoreshwa icyarimwe, ishobora kugera kuri 1.35 kuri icyo gihe × dogere ya vacuum ya 10-4Pa. Umuvuduko wa gaze muri sisitemu upimwa hakoreshejwe agapimisho k’icyuma gisohora amavuta.

Gushyira icyuma mu itanura ridafite umwuka ni ugushyira icyuma mu itanura cyangwa mu cyumba gikoresha umwuka urimo umwuka uvamo. Bikwiriye cyane cyane gushyirisha mu ngingo nini kandi zihoraho. Bikwiriye kandi guhuza ibyuma bimwe na bimwe byihariye, birimo titaniyumu, zirconium, niobium, molybdenum na tantalum. Ariko, gushyirisha mu buryo budafite umwuka bifite ingaruka mbi zikurikira:

① Mu gihe cy’imyanda ivamo umwuka, icyuma cyoroshye guhindagurika, bityo icyuma gikoreshwa mu gusudira .... Iyo bibaye ngombwa, hagomba gufatwa ingamba zijyanye n’ibyo.

② Gukoresha icyuma gifunga ibyuma bivamo umwuka (vacuum brazing) bireba ubukana bw'ubuso, ubwiza bw'aho bihurira ndetse n'uburyo ibice byacyo byihanganira icyuma gifunga ibyuma, kandi bifite ibisabwa byinshi ku bijyanye n'aho bikorera ndetse n'urwego rw'abahanga mu gukora.

③ Ibikoresho byo mu bwoko bwa vacuum biragoye, bifite ishoramari rinini rimwe gusa kandi ikiguzi cyo kubungabunga kiri hejuru.

None se, ni gute washyira mu bikorwa inzira yo gukurura mu itanura ridafite umwuka? Iyo gukurura mu itanura ridafite umwuka, shyiramo ubushuhe bukoresheje ubushuhe mu itanura (cyangwa mu gikoresho cyo gukurura), funga umuryango w'itanura (cyangwa funga umupfundikizo w'icyuma cyo gukurura), hanyuma ushyiremo ubushuhe mbere yo gushyushya. Tangira ipompo ya mechanical mbere, hindura valve yo kuyobora nyuma y'uko igipimo cy'ubushuhe kigeze kuri 1.35pa, funga inzira itaziguye hagati ya pompe ya mechanical n'itanura ridafite umwuka, kora umuyoboro uhujwe n'itanura ridafite umwuka unyuze muri pompe yo gukurura, kora mu gihe gito wishingikirije pompe ya mechanical na pompe yo gukurura, pompe itanura ridafite umwuka uhagije, hanyuma utangire gushyushya amashanyarazi.

Mu gihe cyose cy’izamuka ry’ubushyuhe n’ubushyuhe, icyuma gikoresha umwuka kigomba gukora buri gihe kugira ngo gikomeze kugira uburebure bw’umwuka mu itanura, gikureho umwuka uva mu itanura, gikureho umwuka uva mu itanura, irekurwa rya gaze n’umwuka w’amazi winjira mu rukuta rw’itanura, ibikoresho n’ubushyuhe, hamwe no guhindagurika kw’icyuma na okiside, kugira ngo bigabanye igabanuka ry’umwuka nyaryo. Hari ubwoko bubiri bwo gushyushya umwuka: gushyushya umwuka mwinshi n’igice cy’umwuka (igice cy’umwuka). Gushyushya umwuka mwinshi birakwiriye cyane mu gushyushya icyuma cy’ibanze gifite okiside igoye kubora (nk’urugero nk’icyuma gishyushya nikeli). Gushyushya umwuka igice bikoreshwa mu bihe aho icyuma cy’ibanze cyangwa solder bihindagurika bitewe n’ubushyuhe n’ikirere cy’umwuka mwinshi.

Iyo hagomba gufatwa ingamba zidasanzwe kugira ngo habeho isuku nyinshi, hagomba gukoreshwa uburyo bwo gusukura imvange mbere yo gusiga imvange y'amazi. Mu buryo nk'ubwo, gukoresha uburyo bwo gusukura imvange y'amazi cyangwa imvange y'amazi mbere yo gusiga imvange y'amazi bizafasha kubona umusaruro mwiza mu gusiga imvange y'amazi.
