Ezinqubweni zezimboni ezishisa kakhulu, ukulinganisa izinga lokushisa okunembile nokuthembekile kuyitshe elibalulekile lokulawula ikhwalithi yomkhiqizo, ukuphepha kokusebenza, kanye nokusebenza kahle kwamandla.Amashubhu okuvikela i-thermocouple e-silicon carbide (NB SiC) eboshwe yi-NitrideZivelele njengesixazululo esingcono kakhulu, zisebenzisa izinzuzo ezihambisanayo ze-silicon nitride kanye ne-silicon carbide ukuze ziphumelele ezindaweni ezinzima kakhulu. Ngaphandle kokusebenza kwazo okuhle kakhulu, amakhono ethu okwenza ngokwezifiso aqinisekisa ukuthi ahlanganiswa kalula nezinhlelo ezahlukene zezimboni, okwenza kube ukukhetha okuthandwayo kwabakhiqizi bomhlaba wonke.
Ukusetshenziswa kwamashubhu okuvikela e-NB SiC thermocouple kusabalala ezimbonini eziningi ezifunwa kakhulu, kuqhutshwa yizakhiwo zawo ezivelele—ukuqina kokushisa okuphezulu kuze kufike ku-1500°C, ukumelana okuhle kakhulu nokushaqeka kokushisa, kanye nokumelana nokugqwala okunamandla. Ekucutshungulweni kwensimbi okungeyona i-ferrous, kubalulekile ekulinganisweni kokushisa kuma-aluminium, i-zinc, ithusi, kanye nama-magnesium melting furnaces. Ngokungafani nezinto zendabuko, i-NB SiC ayingcolisi izinsimbi ezincibilikisiwe, iqinisekisa ubumsulwa bemikhiqizo yokugcina ngenkathi igcina ukuzinza kwesikhathi eside. Embonini yensimbi neyensimbi, la mashubhu asebenza ngokuthembekile kuma-blast furnaces kanye nezinqubo zokugoqa ezishisayo, ebekezelela ukukhuhla okuvela othulini olunejubane eliphezulu kanye ne-scoria.
Imikhakha ye-petrochemical kanye neyamakhemikhali izuza kakhulu ekungangeni kwayo kwamakhemikhali, okumelana nokuguguleka kwama-asidi aqinile, ama-alkali, kanye namagesi anobuthi kuma-gasifier amalahle kanye nemikhumbi yokusabela. Isebenza kahle kakhulu futhi ezitshalweni ezisebenzisa imfucuza ibe amandla kanye nasezindaweni zokushisa, ibekezelela izindawo eziyinkimbinkimbi zegesi yomoya oshisayo equkethe i-sulfur nama-chloride. Ngaphezu kwalokho, ezimbonini zobumba, ingilazi, kanye nokwelashwa kokushisa, i-coefficient yabo yokukhulisa ukushisa ephansi (4.7×10⁻⁶/°C ku-1200°C) ivumela ukusebenza okuzinzile ngesikhathi sokushisa okusheshayo kanye nokupholisa, okuqinisekisa ukufundwa okunembile kokushisa.
Amashubhu ethu okuvikela e-NB SiC thermocouple anikeza ukwenza ngokwezifiso okuphelele ukuze kuhlangatshezwane nezidingo zephrojekthi ezihlukile. Ngokuphathelene nobukhulu, sinikeza ububanzi bangaphandle obuguquguqukayo (8mm kuya ku-50mm) kanye nobubanzi bangaphakathi (8mm kuya ku-26mm), obunobude obungenziwa ngokwezifiso obufika ku-1500mm noma ngaphezulu ngokusekelwe emidwebweni. Ukwenza ngokwezifiso kwesakhiwo kufaka phakathi ukubumba okungaboni okukodwa ukuze kuqiniswe ukuqina kanye nezinketho ezahlukene zokufaka—njengezintambo ze-M12×1.5 noma ze-M20×1.5, ama-flange aqinile noma ashukumayo, kanye nemiklamo enemiphetho—ukuze ivumelane kalula nemishini ekhona.
Ukwakheka kwezinto kungalungiswa futhi, ngokuqukethwe kwe-SiC okusukela ku-60% kuya ku-80% kanye nokuqukethwe kwe-Si₃N₄ kusuka ku-20% kuya ku-40%, kulinganisa ukusebenza kanye nezindleko zokugqwala noma izinga lokushisa elithile. Siphinde sinikeze ukwelashwa kwendawo ukuze sinciphise ukugoba (kuze kufike ku-<1% ukugoba kwendawo) futhi sithuthukise ukumelana nokugqwala, kanye nokupakisha okwenziwe ngokwezifiso kokuthutha ibanga elide. Sisekelwa ukulawulwa kwekhwalithi okuqinile kanye nokulethwa okusheshayo (ukuthunyelwa okuphuthumayo kwamahora angu-48 kuyatholakala), siqinisekisa ukusebenza okuqhubekayo kanye nokunikezwa ngesikhathi esifanele.
Khetha amashubhu okuvikela i-thermocouple e-silicon carbide aboshwe yi-nitride ukuze ulinganise izinga lokushisa elithembekile ezindaweni ezinzima. Ubuchwepheshe bethu bokwenza ngokwezifiso buqinisekisa ukulingana okuphelele nezidingo zakho zomkhakha, kunciphisa izindleko zokulungisa kanye nesikhathi sokungasebenzi. Xhumana nathi namuhla ukuze uxoxe ngemininingwane yakho futhi uthole ikhambi elifanele wena.
