I-Silicon Nitride Bonded Silicon Carbide Thermocouple Protection Tube: Esona khuselo siGqibeleleyo soMlinganiselo woBuqondo boShishino

I-Thermocouples ngumqolo wokujongwa kweqondo lokushisa kwiinkqubo ezininzi zemizi-mveliso-ukusuka kwi-metal smelting ukuya kwi-chemical synthesis. Nangona kunjalo, ukusebenza kwabo kunye nobomi babo buxhomekeke ngokupheleleyo kwinto enye ebalulekileyo: ityhubhu yokukhusela. Kwiimeko zoshishino ezinzima, iityhubhu zemveli zokukhusela i-thermocouple (ezenziwe ngetsimbi, i-alumina, okanye i-silicon carbide ecocekileyo) zihlala zisilela ukumelana nobushushu obugqithisileyo, imidiya ebolileyo, okanye amasuntswana abrasive. Oku kukhokelela ekutshintshweni rhoqo kwe-thermocouple, idatha engachanekanga yobushushu, kunye nexesha lokunciphisa imveliso

Ukuba udiniwe kukubeka esichengeni ukuthembeka kwe-thermocouple,I-Silicon Nitride Bonded Silicon Carbide (NSiC) Iityhubhu zokuKhusela iThermocouplesisisombululo somdlalo osidingayo. Yenzelwe ukukhusela i-thermocouples kwezona meko zinzima kakhulu, iityhubhu ze-NSiC ziqinisekisa ukuhambelana, ukuva okuchanekileyo kobushushu ngelixa ukhulisa ubomi benkonzo yezixhobo zakho zokulinganisa ezibalulekileyo.

Kutheni iSilicon Nitride iBonded iSilicon Carbide igqamile kuKhuseleko lweThermocouple

Iityhubhu zokukhusela i-Thermocouple zifuna ibhalansi ekhethekileyo yezakhiwo: ukumelana nobushushu, ukumelana nokugqwala, amandla omatshini, kunye ne-thermal conductivity. I-NSiC iyagqwesa kuzo zonke ezi ndawo, igqwesa izinto zemveli kuzo zonke iimetriki eziphambili:

1. Ukumelana nobushushu obugqithisileyo bokuVava okuNgaphazanyiswa

Ii-Thermocouples kumashishini afana nokwenziwa kweglasi okanye ukugalela ngentsimbi kusebenza kumaqondo obushushu angaphezu kwe-1,500°C. I-NSiC iityhubhu zokukhusela i-thermocouple zibamba oku ngokukhululeka-ziqhayisa ukushisa okusebenzayo okuqhubekayo ukuya kwi-1,600 ° C (2,912 ° F) kunye nokuchasana kwexesha elifutshane kwi-1,700 ° C (3,092 ° F). Ngokungafaniyo neetyhubhu zentsimbi ezixuba okanye zinyibilike, okanye iityhubhu ze-alumina eziqhekeka phantsi komothuko we-thermal, i-NSiC igcina ingqibelelo yolwakhiwo nangexesha lokuguquguquka okukhawulezayo kobushushu. Oku kuthetha ukuba i-thermocouple yakho ihlala ikhuselekile, kwaye idatha yakho yobushushu ihlala ichanekile-nokuba ubushushu buqine kangakanani na.

2. I-Superior Corrosion Resistance to Defete Against Aggressive Media

Iinkqubo zoshishino zihlala ziveza i-thermocouples kwisinyithi esityhidiweyo (i-aluminiyam, i-zinc, i-copper), i-acidic / alkaline solutions, okanye i-corrosive gases (i-sulfur dioxide, i-chlorine). Ulwakhiwo oluxineneyo lwe-NSiC`s, oludityanisiweyo lwe-nitride ludala umqobo ongangenekiyo ngokuchasene nezi zinto. Ngokungafaniyo neetyhubhu ze-silicon carbide ezisulungekileyo, ezityekele kwi-oxidation kwindawo efumileyo yobushushu obuphezulu, ukwakheka okwahlukileyo kwe-NSiC kwandisa ukuxhathisa kwe-oxidation-ukuqinisekisa ukuba i-thermocouple yakho ihlala ikhuselekile ekutshaleni iminyaka. Oku kubalulekile kwizicelo ezifana nokusetyenzwa kweekhemikhali, ukutshiswa kwenkunkuma, kunye nokudibanisa imathiriyeli yebhetri

3. Amandla oomatshini akhethekileyo okumelana nokuNxitywa kunye neMpembelelo

I-Thermocouples kwizityalo zesamente, izikhululo zamandla, okanye izibonelelo zokulungisa izimbiwa zijongene nezoyikiso eziqhubekayo: uthuli oluqhumayo, amasuntswana abhabhayo, kunye nefuthe lomatshini. Iityhubhu ze-NSiC zokukhusela i-thermocouple zakhiwe ukuxhathisa le mingeni, kunye namandla aguquguqukayo angaphezu kwe-300 MPa kunye nobunzima beVickers (HV10) ≥ 1,800. Oku kubenza babe ngamaxesha angama-3-5 ahlala ixesha elide kuneetyhubhu zendabuko, ukunciphisa imfuno yokutshintshwa rhoqo. Kwimisebenzi yakho, oku kuguqulela kwixesha eliphantsi lokuphumla, iindleko ezisezantsi zokulondolozwa, kunye nokusebenza okuthembekileyo kwe-thermocouple.

4. Ukuqhuba kweThermal ngokuKhawuleza, ukuFunda okuchanekileyo

Ixabiso le-thermocouple lisekukwazini ukuphendula ngokukhawuleza kutshintsho lobushushu. I-NSiC`s conductivity ye-thermal (60-80 W / (m·K)) iphezulu kakhulu kune-alumina okanye iityhubhu zetsimbi, eyenza ukutshintshwa kobushushu obukhawulezayo ukusuka kwinkqubo ukuya kwi-junction ye-thermocouple. Oku kuqinisekisa ukuba i-thermocouple yakho inikezela ngexesha langempela, idatha echanekileyo-ibaluleke kakhulu ukugcina ulawulo lwenkqubo kunye nomgangatho wemveliso. Ukongezelela, i-NSiC`s i-coefficient yokwandisa i-thermal ephantsi (3.5-4.5 × 10⁻⁶ / ° C) inciphisa uxinzelelo lwe-thermal, ukuthintela ukuqhekeka okunokuphazamisa ukuchaneka komlinganiselo.

5. Ubomi obude obunexabiso eliphantsi kwiiNdleko zoBunini zizonke

Ngelixa i-NSiC iityhubhu zokukhusela i-thermocouple zinokuba notyalo-mali oluphezulu oluphezulu kuneendlela zendabuko, ubomi babo benkonzo ende (i-2-5 iminyaka kwiimeko ezinzima) kunye neemfuno zokugcinwa okuncinci zinikezela ukugcinwa okubalulekileyo kwexesha elide. Ngokunciphisa i-thermocouple replacement frequency kunye nexesha lokunciphisa imveliso, i-NSiC yehlisa iindleko zakho zizonke zobunini (TCO) kwaye yonyusa imbuyekezo yakho kutyalo-mali (ROI). Kwizityalo zemizi-mveliso ezijonge ukwandisa ukusebenza kakuhle, olu lukhetho olunobulumko, nobungqina bexesha elizayo
