Thermocouples ni inkingi ikomeye yo kugenzura ubushyuhe mu nganda nyinshi—kuva mu gushonga ibyuma kugeza ku gukora imiti. Nyamara, imikorere yazo n'igihe zimara bishingiye ku kintu kimwe cy'ingenzi: umuyoboro wo kurinda. Mu nganda zikomeye, imiyoboro gakondo yo kurinda thermocouple (ikozwe mu byuma, alumina, cyangwa silicon carbide) ikunze kunanirwa kwihanganira ubushyuhe bukabije, ibikoresho byangiza, cyangwa uduce duto two kwangiza. Ibi bituma thermocouple ihora isimburwa, amakuru atari yo y'ubushyuhe, ndetse n'igihe gito cyo kuyikora.
Niba urambiwe kubangamira ubwizigirwa bwa thermocouple,Imiyoboro yo kurinda Silicon Nitride iboheshejwe na Silicon Carbide (NSiC)ni igisubizo gihindura umukino ukeneye. Yakozwe kugira ngo irinde thermocouples mu bihe bigoye cyane, imiyoboro ya NSiSC igenzura ubushyuhe mu buryo buhoraho kandi bunoze, mu gihe yongera igihe cyo gukoresha ibikoresho byawe byo gupima.
Impamvu Silicon Nitride ifatanye na Silicon Carbide igaragara cyane mu kurinda thermocouple
Imiyoboro yo kurinda thermocouple isaba uburinganire bwihariye bw'imiterere: kurwanya ubushyuhe, kurwanya ingese, imbaraga za mekanike, no gutwara ubushyuhe. NSiC irakomeye muri izi nzego zose, irusha ibikoresho gakondo muri buri gipimo cy'ingenzi:
1. Ubudahangarwa bw'ubushyuhe bukabije ku buryo bwo kumva ibintu bidasubirwaho
Imashini zikoresha thermocouple mu nganda nko gukora ibirahuri cyangwa gucukura ibyuma zikora mu bushyuhe burenga 1,500°C. Imashini zirinda thermocouple za NSiC zibikora byoroshye—zifite ubushyuhe buhoraho bugera kuri 1,600°C (2,912°F) kandi zirwanya 1,700°C mu gihe gito. Bitandukanye n'imashini zikoresha ibyuma zikora ogisijeni cyangwa zishonga, cyangwa imashini za alumina zicika bitewe n'ubushyuhe, NSiC igumana imiterere yayo ndetse no mu gihe cy'ihindagurika ryihuse ry'ubushyuhe. Ibi bivuze ko thermocouple yawe iguma irinzwe, kandi amakuru y'ubushyuhe bwawe agakomeza kuba ay'ukuri—uko ubushyuhe bwaba bungana kose.
2. Ubudahangarwa Bukomeye bwo Kurwanya Itangazamakuru Rirwanya Iterabwoba
Inganda zikunze gushyira thermocouples mu byuma bishongeshejwe (aluminium, zinc, umuringa), aside/alkaline, cyangwa imyuka ihumanya (dioxide de sulfure, chlorine). Imiterere ya NSiC ifite nitride nyinshi kandi ifatanye n’ibintu biyirinda. Bitandukanye n’imiyoboro ya silicon carbide, ikunda gushonga mu bidukikije bifite ubushyuhe bwinshi, imiterere yihariye ya NSiC yongera ubushobozi bwo kudashonga—bituma thermocouple yawe iguma irinzwe kwangirika mu gihe cy’imyaka myinshi. Ibi ni ingenzi cyane mu bikorwa nko gutunganya imiti, gutwika imyanda, no gukora ibikoresho bya bateri.
3. Imbaraga zidasanzwe za mekanike zo kwihanganira kwangirika n'ingaruka
Imashini zikoresha thermocouple mu nganda za sima, mu bigo by'amashanyarazi, cyangwa mu nganda zitunganya amabuye y'agaciro zihura n'ibibazo bihoraho: ivumbi rikabije, uduce duto duguruka, n'ingaruka za mekanike. Imashini zirinda thermocouple za NSiC zubatswe kugira ngo zirwanye ibi bibazo, zifite imbaraga zo kuzunguruka zirenga MPa 300 n'ubukana bwa Vickers (HV10) bwa ≥ 1,800. Ibi bituma ziramba inshuro 3-5 kurusha imashini zisanzwe, bigabanya gukenera kuzisimbuza kenshi. Ku bikorwa byawe, ibi bivuze ko igihe cyo gukora kigabanuka, amafaranga make yo kuzisana agabanuka, ndetse n'imikorere myiza ya thermocouple.
4. Uburyo bwiza bwo gutwara ubushyuhe kugira ngo usome vuba kandi neza
Agaciro ka thermocouple gashingiye ku bushobozi bwayo bwo gusubiza vuba impinduka z'ubushyuhe. Uburyo bwo gutwara ubushyuhe bwa NSiC (60–80 W/(m·K)) buri hejuru cyane ugereranije n’ubw’imiyoboro ya alumina cyangwa ibyuma, bigatuma ubushyuhe bwihuta buva muri iyo nzira bujya mu ihuriro rya thermocouple. Ibi bituma thermocouple yawe itanga amakuru nyayo kandi nyayo—ni ingenzi mu kubungabunga uburyo bwo kugenzura no kunoza ubwiza bw’ibicuruzwa. Byongeye kandi, ingano nto y’ubushyuhe bwa NSiC (3.5–4.5 × 10⁻⁶/°C) igabanya ubushyuhe, ikarinda ko ibipimo byangirika.
5. Igihe cyo Kuramba Gihendutse ku Giciro Gito cy'Ubwishingizi
Nubwo imiyoboro yo kurinda thermocouple ya NSiC ishobora kugira ishoramari ryinshi rya mbere ugereranije n’uburyo busanzwe, igihe cyayo kirekire cyo gukora (imyaka 2-5 mu bihe bikomeye) no kudakenera gusana bitanga ubwizigame bunini bw’igihe kirekire. Mu kugabanya inshuro zo gusimbuza thermocouple n’igihe cyo gukora, NSiC igabanya ikiguzi cyose cyo gutunga (TCO) kandi yongera inyungu ku ishoramari ryawe (ROI). Ku nganda zishaka kunoza imikorere, iyi ni amahitamo meza kandi ahamye y’ejo hazaza.
