Ukwelashwa kokushisa kwe-vacuumkuyinqubo eyinhloko yokuthuthukisa izakhiwo ezingokomzimba nezomshini zezingxenye zensimbi.Kubandakanya ukushisa insimbi ekamelweni elivaliwe ekushiseni okuphezulu ngenkathi kugcinwa ukucindezela okuphansi, okubangela ukuba ama-molecule egesi aphume futhi enze inqubo yokushisa efanayo.Elinye lamathuluzi abalulekile asetshenziswa ekwelapheni ukushisa kwe-vacuum isithando somlilo se-vacuum, esingalawula ngokunembile izinga lokushisa, umkhathi nokucindezela kule nqubo.
Ukuqina kwe-vacuum kuyindlela evamile esetshenziswa abakhiqizi ukukhulisa amandla nobulukhuni bezingxenye zensimbi.Ngokushisisa insimbi emazingeni okushisa aphezulu esithandweni se-vacuum, iba nenguquko ebizwa ngokuthi i-austenitization, eyenza i-microstructure efanayo futhi ithuthukise izakhiwo zemishini.Le nqubo ijwayele ukusetshenziselwa ukuqinisa izinto ezifana nensimbi, i-titanium nama-superalloys asetshenziswa kakhulu ekusetshenzisweni kokucindezeleka okuphezulu.
Ukwelashwa kokushisa kwe-vacuum kubalulekile hhayi ekwenzeni ukuqina kuphela, kodwa nakwezinye izinqubo ezimbalwa ezifana nokubhula, ukucwilisa kanye nokudonsa.Inikeza izinzuzo ezimbalwa kunezindlela zokwelashwa ezivamile zokushisa, okuhlanganisa ikhwalithi ephezulu nokuphindaphindeka, ukuhlanekezela okuncishisiwe, kanye nekhono lokusebenzisa ama-alloys asebenza kahle njengalawo atholakala ku-aerospace kanye nezimboni zezokwelapha.Unalokhu engqondweni, kuyacaca ukuthi ukwelashwa kokushisa kwe-vacuum kuyinqubo ebalulekile ezimbonini eziningi, ukuletha ukusebenza kwengxenye okuthuthukisiwe ngokusebenza kahle okukhulu nokuthembeka.
Lapho ukhetha i-aisithando somlilo se-vacuum, izici eziningana kufanele zicatshangelwe, njengohlobo lwesithando somlilo (inqwaba noma eqhubekayo), izinga lokushisa eliphezulu kanye nosayizi wegumbi lomlilo.Ukukhetha isithando somlilo esifanele kuzoncika ekusetshenzisweni okuqondile kanye nohlobo lwezinto ezicutshungulwayo.Isithando somlilo esilungile singasindisa amandla, sithuthukise ikhwalithi yomkhiqizo futhi sinciphise izindleko zokucubungula, kuyilapho isithando somlilo esingalungile singathinta kakhulu ikhwalithi yomkhiqizo wokugcina.
Ngamafuphi, ukwelashwa kokushisa kwe-vacuum kuyinqubo ebalulekile yokuthuthukisa ukusebenza kwezingxenye zensimbi.Ukukhetha isithando somlilo esifanele kubalulekile empumelelweni yenqubo yakho, ukwandisa ukwelashwa kokushisa nokuqinisekisa ikhwalithi yomkhiqizo.I-Aerospace, yezimoto, yezokwelapha, nezinye izimboni eziningi zithembele ekwelashweni kokushisa kwe-vacuum, ngakho ukuthola umhlinzeki othembekile wale nqubo kubalulekile.
