Uburyo bwo gukora HL Cryogenics bukurikiza aya mahame yose y'igihugu.
Impamvu z'Ubwubatsi zishingiye ku bisabwa mu gutanga icyemezo
Impamyabushobozi si urutonde rw'ibintu bitagira icyo bigamije—zishingiye ku mahame shingiro y'ubuhanga agira ingaruka ku mikorere n'umutekano wa sisitemu. Tekereza uburyo butatu bw'ingenzi bwo kohereza ubushyuhe: gukwirakwiza, gukwirakwiza umuriro, n'imirasire. Mu buryoUmuyoboro urinda ubushyuhe mu cyumacyangwa umuyoboro ushyushye, icyuma gifunga ubushyuhe kiri hagati y’imiyoboro y’imbere n’iy’inyuma gikuraho burundu uburyo ubushyuhe buhindagurika, kikagabanya ubushyuhe buva ku kigero kirenga 90% ugereranije n’imiyoboro isanzwe ishyushya. Uku kugabanuka gukomeye k’ubushyuhe buvamo kugabanuka kw’umuvuduko wo kubira, kugabanuka kw’ikiguzi cyo gukora, no kugabanuka k’ubushyuhe mu buryo buhoraho.
Ariko, gukomeza iyo vacuum uko igihe kigenda gihita ni ikibazo. Ndetse no kuva imyuka idafite ubushobozi bwo kuyisukura cyangwa kuyisohora mu bikoresho by’imbere bishobora kwangiza imikorere yayo buhoro buhoro. Niho duhera.Sisitemu yo gupompa ikoresha umwuka ushyushyeBigaragara. Bitandukanye na sisitemu za "passive vacuum" zigenda zigabanuka uko igihe kigenda gihita, sisitemu yacu ihora ikura imyuka idafite aho ihuriye n’ingufu mu gice cy’amazi, igakomeza gukora neza mu gihe cyose cy’imikorere ya sisitemu. Ubu buryo bufatika bwo gucunga "vacuum cleaner" ni ikintu cy’ingenzi gitandukanya ibigo by’ubugenzuzi - niyo mpamvu sisitemu zacu zihora zitsinda ibizamini bikomeye by’imikorere y’igihe kirekire.
Guhitamo ibikoresho ni ikindi gice aho ibisabwa mu byemezo bituma habaho ubuhanga mu by’ubuhanga. Mu bushyuhe bukabije, ibyuma byinshi bisanzwe biracika intege kandi bishobora kwangirika. Dushyiraho ibyuma bitagira umugese nka 304L na 316L ku miyoboro yacu y’imbere kuko bigumana imbaraga no kudakira ingese ndetse no kuri -269°C. Amakoti yacu yo hanze atoranywa hashingiwe ku miterere y’ibidukikije byihariye—inyubako zo ku nkombe zishobora gusaba uburinzi buhanitse bw’ingese, mu gihe inyubako zo mu butayu zishobora gushyira imbere ubudahangarwa bw’imirasire y’izuba.
Kugabanuka k'ubushyuhe ni ikindi kintu cy'ingenzi cyo kwitaho. Iyo sisitemu yo kwimura ikoresheje ubushyuhe bukabije ikonje kuva ku bushyuhe bw'ikirere kugeza ku bushyuhe bwo gukora, imiyoboro igabanuka cyane. Iyo ingingo zo kwaguka, imiterere, cyangwa ibice byoroshye bidakozwe neza, uku kugabanuka gushobora gutera imihangayiko yangiza.Umuyoboro w'amazi ushyushye ukoresha amashanyaraziibicuruzwa byakozwe mu buryo bwihariye kugira ngo bihuze n'iyi mikorere, bitanga uburyo bworoshye bwo kwitandukanya n'ubushyuhe ndetse no koroshya imikorere ya mekanike mu guteranya kumwe.
