I-Silicon Nitride Bonded Silicon Carbide Thermocouple Protection Tube: Isivikelo Esiphelele Sokulinganisa Izinga Lokushisa Lezimboni

Ama-thermocouple angumgogodla wokuqapha izinga lokushisa ezinqubweni eziningi zezimboni—kusukela ekuncibilikiseni insimbi kuya ekuhlanganisweni kwamakhemikhali. Noma kunjalo, ukusebenza kwawo kanye nesikhathi sawo sokuphila kuncike ngokuphelele esicini esisodwa esibalulekile: ithubhu lokuvikela. Ezindaweni zezimboni ezinzima, amashubhu okuvikela e-thermocouple endabuko (enziwe ngensimbi, i-alumina, noma i-silicon carbide emsulwa) avame ukwehluleka ukumelana nokushisa okukhulu, izinto ezibolile, noma izinhlayiya ezihudulayo. Lokhu kuholela ekushintsheni kwe-thermocouple njalo, idatha yokushisa enganembile, kanye nesikhathi sokukhiqiza esibizayo.​

Uma ukhathele ukuyekethisa ekuthembekeni kwe-thermocouple,Amashubhu Okuvikela Ama-Thermocouple E-Silicon Nitride Aboshwe yi-Silicon Carbide (NSiC) e-Thermocoupleyisisombululo esishintsha umdlalo osidingayo. Eklanyelwe ukuvikela ama-thermocouple ezimweni ezinzima kakhulu, amashubhu e-NSiC aqinisekisa ukuzwa okushisa okulinganayo nokunembile ngenkathi ekhulisa impilo yesevisi yemishini yakho yokulinganisa ebalulekile.

Kungani i-Silicon Nitride Bonded Silicon Carbide Ivelele Ekuvikelweni kwe-Thermocouple​

Amashubhu okuvikela e-thermocouple adinga ibhalansi ehlukile yezakhiwo: ukumelana nokushisa, ukumelana nokugqwala, amandla omshini, kanye nokuqhuba ukushisa. I-NSiC ihamba phambili kuzo zonke lezi zindawo, isebenza kangcono kunezinto zendabuko kuzo zonke izindlela ezibalulekile zokulinganisa:

1. Ukumelana Nokushisa Okukhulu Kokuzwa Okungaphazanyiswa​

Ama-thermocouple ezimbonini ezifana nokukhiqiza ingilazi noma ukuthungwa kwensimbi asebenza emazingeni okushisa angaphezu kuka-1,500°C. Amashubhu okuvikela ama-thermocouple e-NSiC aphatha lokhu kalula—anezinga lokushisa lokusebenza eliqhubekayo elifika ku-1,600°C (2,912°F) kanye nokumelana kwesikhashana ku-1,700°C (3,092°F). Ngokungafani namashubhu ensimbi ancibilikisa noma ancibilikisayo, noma amashubhu e-alumina aqhekeka ngaphansi kokushaqeka kokushisa, i-NSiC igcina ubuqotho besakhiwo ngisho nangesikhathi sokushintshashintsha kwezinga lokushisa okusheshayo. Lokhu kusho ukuthi i-thermocouple yakho ihlala ivikelekile, futhi idatha yakho yokushisa ihlala inembile—kungakhathaliseki ukuthi ukushisa kukhulu kangakanani.​

2. Ukumelana Okuphezulu Kokugqwala Ukuvikela Abezindaba Abanolaka​

Izinqubo zezimboni zivame ukudalula ama-thermocouple ezinsimbini ezincibilikisiwe (i-aluminium, i-zinc, ithusi), izixazululo ze-acidic/alkaline, noma amagesi agqwalisayo (i-sulfur dioxide, i-chlorine). Isakhiwo esiqinile, esinama-nitride se-NSiC sidala isithiyo esingenakungeneka ngokumelene nalezi zinto. Ngokungafani namashubhu e-silicon carbide ahlanzekile, avame ukugqwala ezindaweni ezimanzi ezishisa kakhulu, ukwakheka okuhlukile kwe-NSiC kuthuthukisa ukumelana nokugqwala—ukuqinisekisa ukuthi i-thermocouple yakho ihlala ivikelekile ekugqwaleni iminyaka eminingi. Lokhu kubalulekile ezinhlelweni ezifana nokucubungula amakhemikhali, ukushiswa kwemfucuza, kanye nokuhlanganiswa kwezinto zebhethri.​

3. Amandla Akhethekile Okusebenza Kwemishini Okumelana Nokuguguleka Nomthelela​

Ama-thermocouple ezitshalweni zesimende, eziteshini zikagesi, noma ezindaweni zokucubungula amaminerali abhekene nezinsongo eziqhubekayo: uthuli oluvuthayo, izinhlayiya ezindizayo, kanye nokushayisana komshini. Amashubhu okuvikela ama-thermocouple e-NSiC akhiwe ukuze amelane nalezi zinselele, ngamandla aguquguqukayo angaphezu kwama-300 MPa kanye nobunzima be-Vickers (HV10) obungu-≥ 1,800. Lokhu kuwenza aqine ngokuphindwe kathathu kuya kahlanu kunamashubhu endabuko, kunciphisa isidingo sokushintsha njalo. Emisebenzini yakho, lokhu kusho ukuthi isikhathi sokungasebenzi sincane, izindleko zokulungisa eziphansi, kanye nokusebenza kwe-thermocouple okuthembekile kakhudlwana.​

4. Ukushisa Okuhle Kakhulu Kokufunda Okusheshayo Nokunemba​

Inani le-thermocouple lisekhonweni layo lokuphendula ngokushesha ezinguqukweni zokushisa. Ukuqhuba kokushisa kwe-NSiC (60–80 W/(m·K)) kuphakeme kakhulu kune-alumina noma amashubhu ensimbi, okuvumela ukudluliselwa kokushisa okusheshayo kusuka enkambisweni kuya endaweni yokuhlangana kwe-thermocouple. Lokhu kuqinisekisa ukuthi i-thermocouple yakho iletha idatha yesikhathi sangempela nenembile—ebalulekile ekugcineni ukulawulwa kwenqubo kanye nekhwalithi yomkhiqizo. Ngaphezu kwalokho, i-coefficient yokwanda kokushisa okuphansi kwe-NSiC (3.5–4.5 × 10⁻⁶/°C) inciphisa ukucindezeleka kokushisa, ivimbela imifantu engase iphazamise ukunemba kokulinganisa.​

5. Isikhathi Eside Esisebenza Kahle Ngezindleko Zezindleko Eziphansi Zobunikazi​

Nakuba amashubhu okuvikela e-NSiC thermocouple angase abe nokutshalwa kwezimali kokuqala okuphezulu kunezinketho zendabuko, impilo yawo yesevisi ende (iminyaka engu-2-5 ezimweni ezinzima) kanye nezidingo zokunakekelwa okuncane kuletha ukonga okukhulu kwesikhathi eside. Ngokunciphisa imvamisa yokushintsha i-thermocouple kanye nesikhathi sokungasebenzi kokukhiqiza, i-NSiC yehlisa izindleko zakho eziphelele zobunikazi (i-TCO) futhi ikhuphule imbuyiselo yakho ekutshalweni kwezimali (i-ROI). Ezitshalweni zezimboni ezifuna ukuthuthukisa ukusebenza kahle, lokhu kuyisinqumo esihlakaniphile nesivikela ikusasa.​
