Umuyoboro wa Safiro wo kurinda Thermocouple - Ubushyuhe bwinshi mu bidukikije bikomeye

Ibisobanuro bigufi:

Imiyoboro ya safiro, ikozwe muri okiside ya aluminiyumu imwe (Al₂O₃), ni ibice bikora neza cyane bikoreshwa cyane mu nganda zitandukanye. Uruvange rwabyo rudasanzwe rwo kwirinda ubushyuhe, imbaraga za mekanike, kudahungabana kwa shimi, no kubona urumuri byatumye biba ingenzi mu bidukikije bikabije. Imwe mu miyoboro y'agaciro kandi ikoreshwa cyane ni mu kurinda thermocouples—ibikoresho bipima ubushyuhe akenshi bikora mu bihe bikomeye, ubushyuhe bwinshi, cyangwa byangiza. Iyi nkuru itanga incamake yimbitse y'imiterere ya safiro tube, imiterere y'ingenzi, imiyoboro y'ingenzi, cyane cyane uruhare rwabyo mu kurinda thermocouple.

Intangiriro

Kuki imiyoboro ya Safira itanga imikorere myiza cyane?

Imiyoboro ya safiro izwiho ubushobozi bwo kubungabunga imiterere n'imikorere yayo mu gihe cy'umuvuduko ukabije w'umubiri n'imiti. Mu buryo bw'umuvuduko mwinshi, ikoreshwa nk'imiyoboro yo kubikamo ibintu ndetse n'amadirishya yo kureba, itanga ahantu heza kandi hatarangwa n'amazi yo gusesengura amazi n'imyuka. Bitewe n'imbaraga zayo nyinshi zo gukanda no kudakora neza, imiyoboro ya safiro ikwiriye kandi ahantu hafite ingaruka zikomeye ku mashini cyangwa ubushyuhe bwinshi.

Izi mashini zidasanzwe mu bushobozi bwazo bwo gukora ku bushyuhe bugera kuri 2000°C zidakonjesha cyangwa ngo zihinduke. Bitandukanye n'ibindi bikoresho byinshi bya ceramic cyangwa ikirahure, safiro igumana imiterere yayo n'ubushobozi bwayo bwo gukora ndetse no mu bushyuhe buri hejuru. Iyi mikorere ni ingenzi mu ikoreshwa aho ingano zihamye zigomba gukoreshwa mu gufunga, gukingira, cyangwa guhuza—nk'uko bimeze mu micungire y'ibikoresho bya thermocouple.

Umucyo wazo mu buryo bwagutse—kuva kuri ultraviolet (0.3 μm) kugeza ku isura igaragara kugeza kuri infrared (5 μm)—zongeraho urundi rwego rw'imikorere. Iyi miterere yemerera imiyoboro ya safiro gukora nk'ibice by'imiterere gusa, ahubwo no gushyigikira sisitemu z'urumuri zihujwe zo kugenzura mu gihe nyacyo no gupima hakoreshejwe laser.

Imiyoboro ya Safiro mu Burinzi bwa Thermocouple

Thermocouples ni ibikoresho by'ingenzi bipima ubushyuhe bikoreshwa mu nganda zitandukanye kuva ku byuma bikoresha ikirere no mu byuma kugeza ku gukora semiconductor no gutunganya imiti. Ariko, thermocouples ni ibikoresho bishobora kwangirika vuba iyo bihuye n'imyuka ikora nabi, ibidukikije bya plasma, cyangwa ibihe by'ubushyuhe/ubukonje byihuse. Kugira ngo birinde ibi bibazo, imiyoboro ya safiro ikora nk'ibikoresho byiza byo kurinda thermocouples.

Uburyo ubushyuhe bwa safiro butuma ubushyuhe bwihuta kandi neza bugera kuri thermocouple iri mu muyoboro, bigatuma ubushyuhe bukurikiranwa mu buryo bwihuse kandi burambye mu gihe cy’igihe runaka, bikingira sensor ibintu byangiza, kwangirika kw’ibikoresho, no guhungabana k’ubushyuhe. Uku kuringaniza kw’ubushyuhe n’uburyo butwara ibintu bituma imiyoboro ya safiro iba ikwiriye cyane mu kurinda thermocouple mu bidukikije bibi.

Byongeye kandi, kudakora neza kwa shimi ya safiro birinda kwanduza ibidukikije. Ibi ni ingenzi cyane mu bikorwa bifite isuku nyinshi nko gutunganya wafer ya semiconductor, sisitemu zo gusukura ibyuma mu buvuzi, cyangwa ibyumba bishyushya bifite isuku nyinshi. Kuba nta reaction hagati ya safiro n'ibinyabutabire bikomeye nka fluorine plasma, aside hydrochloric, cyangwa ibyuma bishongeshejwe bituma sisitemu ikora neza kandi igapima neza.

Byongeye kandi, imiyoboro ya safiro irakomera cyane kwangirika kandi ntiyononekara iyo imaze igihe kinini ihuye n'uduce dukoresha ingufu nyinshi cyangwa imirasire ikomeye ya UV / IR. Uku gukomera kwongera igihe cyo kubaho kwa sensor za thermocouple, bigabanya ikiguzi cyo kubungabunga no kudakora neza kwa sisitemu.

Imikoreshereze yagutse y'imiyoboro ya Safiro

Nubwo kurinda thermocouple ari imwe mu mikoreshereze idasanzwe, imiyoboro ya safiro ikoreshwa cyane mu zindi nzego z’ikoranabuhanga rigezweho n’inganda. Muri zo harimo:

Gutunganya Plasma: Imiyoboro ya safiro ikora nk'aho ifungira mu buryo bwo gukata no gushyiramo plasma, aho ubushobozi bwayo bwo kurwanya ibinyabutabire bubuza ko uduce duto twangirika.
Amatara ashyushye cyane: Ubushobozi bwazo bwo kubona neza no kudakoresha ubushyuhe butuma ziba amabahasha meza yo gukoresha amatara ya UV, aboneka, n'ay'urumuri rwa IR.
Gutunganya Amazi no Gutera Gazi: Imiyoboro ya safiro ikoreshwa mu buryo aho hakenewe kugenzura neza amazi cyangwa imyuka iri mu muvuduko mwinshi.
Ibikoresho by'ubuvuzi n'imitiBitewe n’ubushobozi bwazo bwo kudakora neza, imiyoboro ya safiro ifite umutekano wo kuyikoresha mu bikoresho byasizwe imiti cyangwa bishobora guterwa.
Isesengura rya Spectroscopy n'Amaso: Umucyo wazo w’amatara utuma habaho guhuza neza muri sisitemu za spectroscopy kugira ngo hamenyekane ibinyabutabire cyangwa ibya biyoloji.

Muri izi nzego zose, imiyoboro ya safiro itanga imbaraga zidasanzwe mu byuma no kurwanya imiti, bigatuma ikora neza mu gihe cy’akazi gakomeye.

Ibiranga by'ingenzi by'imiyoboro ya Safiro

Imiyoboro ya safiro ifite uruvange rudasanzwe rw'ibintu byiza:

Ingano nini y'ihererekanyamakuru ry'urumuri: Kuva kuri 0.3 μm (UV) kugeza kuri 5 μm (IR), ikwiriye gukoreshwa muri sisitemu za laser, kugenzura urumuri, no gupima ahantu hakorerwa.
Ubukomere Bukabije: Iyo ubukana bwa Mohs ari 9, safiro ntishobora gushwaragurika, irutwa gusa na diyama.
Ahantu hashongesha cyane: Safira igumana imiterere yayo kugeza kuri 2030°C.
Ubushobozi budasanzwe bwo gutwara ubushyuhe: Yohereza ubushyuhe neza, ni ingenzi mu gukoresha thermocouple.
Guhagarara kw'ibinyabutabire: Irwanya aside, alkali, n'ibyuma bishongeshejwe, uretse umunyu ushyushye wa caustic.
Ubushyuhe bwinshi bw'amashanyarazi: Ni byiza cyane mu gukingira amashanyarazi hakoreshejwe ikoranabuhanga n'amashanyarazi menshi.
Ihindagurika ry'ibipimo: Igumana ubuziranenge mu gihe cy'ubushyuhe cyangwa umutwaro wa mekanike.

Ibyiza byo gukoresha imiyoboro ya Safira kuri Thermocouples

Guhuza imiyoboro ya safiro mu nteko za thermocouple bitanga inyungu nyinshi:

Uburyo bwo kunoza uburyo bwo gupima ibyuma bipima amashanyarazi: Uburyo ubushyuhe butwara butera inkunga yo kumenya ubushyuhe bwihuse.
Igihe kirekire cyo gukoresha sensor: Kurwanya ingese no kwangirika birinda thermocouple y'imbere.
Kugabanya igihe cyo kuruhuka: Inshuro nke zo gucika intege kwa sensor no gukenera kongera gukoresha uburyo bwo kuyikosora.
Ubuziranenge bwa sisitemu: Kudakora neza kw'ibinyabutabire birinda kwanduzanya, ni ingenzi mu bikorwa byo gusukura.
Imikorere myinshi: Ihuza uburinzi bw'ubushyuhe n'ubukonje bw'urumuri kugira ngo ikoreshwe mu buryo bubiri mu kumenya no kugenzura.
