icyuma kitagira ibyuma ni ubwoko bwa valve ikozwe mubikoresho byuma bidafite ingese, kubera ko irwanya ruswa nziza, imbaraga zubushyuhe bwo hejuru hamwe na okiside, ikoreshwa cyane muri peteroli, imiti, metallurgie, ubwubatsi nizindi nganda. Uru rupapuro ruzasesengura guhitamo ibikoresho nibikorwa biranga ibyuma bitagira umwanda.
Icya mbere, guhitamo ibikoresho
Ibikoresho byibyuma bitagira umwanda nibyuma cyane cyane ibyuma bya austenitike, ibyuma bya ferritic ibyuma na austenitis ferritic duplex ibyuma bitagira umuyonga.
1. Icyuma cya Austenitike: Icyuma cya Austenitike kitagira ibyuma birimo chromium, nikel nibindi bintu, hamwe no kurwanya ruswa hamwe nubushyuhe bwo hejuru, bikwiranye nubushyuhe bwinshi, umuvuduko mwinshi hamwe nibitangazamakuru byangirika. Ibyuma bisanzwe bya austenitis bitagira ibyuma 304, 316 nibindi.
2. Ibyuma bidafite ibyuma bya ferritike: ferritic stainless ibyuma birimo chromium, nikel, molybdenum nibindi bintu, hamwe nimbaraga nyinshi, kurwanya okiside hamwe no kwihanganira kwambara, bikwiranye nubushyuhe bwinshi, umuvuduko mwinshi hamwe na okiside mugihe giciriritse. Ibyuma bisanzwe bya ferritic 410, 420 nibindi.
3. Austenitike ferritic duplex ibyuma bidafite ibyuma: Austenitic ferritic duplex ibyuma bitagira ibyuma bifite ibyiciro bibiri bya austenitike na ferritic, bihuza kwangirika kwangirika kwicyuma cya austenitis hamwe nimbaraga nyinshi zicyuma cya ferritic, kandi gikwiranye nakazi gakomeye. Ibisanzwe duplex idafite ibyuma 2205, 2507 nibindi.
Icya kabiri, ibiranga imikorere
Imikorere iranga ibyuma bitagira umwanda bigaragarira cyane cyane mubice bikurikira:
1. Kurwanya ruswa nziza cyane: ibyuma bitagira umwanda bifite ibyuma birwanya ruswa kandi birashobora kurwanya ruswa yibitangazamakuru bitandukanye, bikagabanya ibiciro byo gufata neza ibikoresho no kubisimbuza.
2. Ubushyuhe bwo hejuru: icyuma kitagira umuyonga gifite imbaraga zubushyuhe bwo hejuru, kirashobora kugumana imiterere yubukanishi ahantu h’ubushyuhe bwo hejuru, bukwiranye nubushyuhe bwinshi, akazi gakomeye.
3. Kurwanya Oxidation: icyuma kitagira umuyonga gifite imbaraga zo kurwanya okiside, gishobora kurwanya kwangirika kwitangazamakuru rya okiside no kuzamura ubuzima bwa serivisi ya valve.
4. Kwambara kwambara: Ibyuma bitagira umuyonga bifite ibyuma birwanya kwambara, bishobora kugabanya kwambara kwa valve mugihe cyo gukoresha no kugabanya ibiciro byo gufata neza ibikoresho no kubisimbuza.
5. Imikorere myiza yo gufunga: ibyuma bitagira umuyonga bifata imiterere yo gufunga neza, bifite imikorere myiza yo gufunga, bigabanya ibyago byo kumeneka, kandi bikarinda umutekano nubwizerwe bwibikorwa byibikoresho.
Muncamake, icyuma kitagira umuyonga muguhitamo ibikoresho, cyane cyane ukurikije uko akazi gakorwa kugirango uhitemo ibyuma bya austenitike bitagira ibyuma, ibyuma bya ferritic cyangwa ibyuma bya austenitis ferritic duplex ibyuma bitagira umuyonga. Kubireba imikorere iranga ibyuma bitagira umwanda, bifite imbaraga zo kurwanya ruswa, imbaraga zubushyuhe bwo hejuru, kurwanya okiside, kwambara no gukora neza, kandi bikoreshwa cyane mubikorwa bitandukanye byinganda.
