I-Silicon carbide ityhubhu yokukhusela i-thermocouple
I-Silicon Carbide Thermocouple Protection Tube: IShield eSebenza ngokuPhezulu kwiiMeko eziBabekileyo
Ziziphi izinto eziluncedo kwiSilicon Carbide Thermocouple Protection Tubes?
Iityhubhu zokukhusela i-silicon carbide thermocouple, eyaziwa ngokuba yinto ehlala ixesha elide kunye nokusebenza kwayo, iyimfuneko kwizicelo ezifuna ukuchaneka komlinganiselo wobushushu obuphezulu kunye nokuqina. Ngokumelana nobushushu okumangalisayo ukuya kuthi ga kwi-1550 ° C (2800 ° F), iityhubhu ze-silicon carbide zikhusela ngokufanelekileyo i-thermocouples kwiindawo ezinomngeni, ziqinisekisa ukuchaneka kumashishini afana nokunyibilika kwe-aluminium, isinyithi, kunye neeseramikhi. Iimpawu ezikhethekileyo ze-silicon carbide nazo zivumela ukuba zixhathise i-oxidation, i-corrosion, kunye ne-thermal shock-impawu ezidlula izinto eziqhelekileyo ezifana ne-alumina kunye ne-graphite kwizicelo ezithile.
Kutheni ukhetha iSilicon Carbide yoKhuseleko lweThermocouple?
I-Silicon carbide, i-hardware yobunjineli enzima kunye ne-thermal conductivity ephezulu kunye nokuchasana okukhethekileyo kwiikhemikhali, inika ukhuseleko oluqinileyo kwiintsimbi ezityhidiweyo ezifana ne-aluminium kunye ne-zinc. Nantsi into eyenza icace:
- I-High Thermal Conductivity: I-silicon carbide ye-thermal conductivity egqwesileyo iqinisekisa ukutshintshwa kobushushu ngokukhawuleza, ukuphucula ukuvakalelwa kweqondo lokushisa kunye nokuchaneka kwizicelo zexesha langempela.
- I-Oxidation kunye noKunyangwa kokuNgxwala: Izinto eziphathekayo zihlala zizinzile nangona zibonakaliswe kwiigesi ezinobungozi okanye isinyithi esinyibilikisiweyo, ukukhusela i-thermocouples ekuthotyweni kunye nokwandisa ubomi babo.
- I-Porosity ephantsi: Ngenqanaba le-porosity malunga ne-8%, iityhubhu ze-silicon carbide thermocouple zithintela ungcoliseko kwaye zigcine ingqibelelo ephezulu yesakhiwo phantsi kobushushu obuphezulu obuqhubekayo.
Iimpawu eziphambili kunye nezicelo
| Uphawu | Inkcazo |
|---|---|
| Uluhlu lobushushu | Ukuya kuthi ga kwi-1550°C (2800°F) |
| Ukunyangwa kweThermal Shock | Igqwesileyo kutshintsho olukhawulezayo lobushushu |
| Uzinzo lweMichiza | Ukumelana ne-asidi, i-alkali, kunye ne-slag |
| Izinto eziphathekayo | I-silicon carbide ecinezelwe ngokufihlakeleyo |
| I-Porosity | Phantsi (8%), ukuphucula ukuqina |
| Ubungakanani obukhoyo | Ubude be-12" ukuya kwi-48"; 2.0" OD, izifakelo zeNPT ziyafumaneka |
Ezi tyhubhu zisetyenziswa ngokuqhelekileyo kwiziko lobushushu obuphezulu kunye neziko lokunyibilikisa i-aluminium, apho ukumanzisa kwazo okuphantsi kunye ne-aluminium etyhidiweyo kunceda ukunciphisa imfuno yokugcinwa rhoqo. Ngaphaya koko, amandla agqwesileyo e-silicon carbide kunye nokumelana nokunxiba kuyenza ibe lolona khetho lufanelekileyo lwenkonzo eyandisiweyo kwiziko lemveliso kunye neziko, apho ikhusela ngokufanelekileyo uhlaselo lwe-slag kunye ne-oxidation.
Imibuzo Ebuzwa Rhoqo (FAQ)
1. I-silicon carbide ithelekisa njani kunye nezinye izixhobo zokukhusela ityhubhu?
I-silicon carbide yodlula i-alumina kunye nezinye iiseramics kwizicelo zobushushu obuphezulu ngenxa yokumelana nokothuka kwe-thermal kunye nokuzinza kwe-oxidation. Ngelixa zombini i-alumina kunye ne-silicon carbide inokumelana nobushushu obuphezulu, i-silicon carbide iyagqwesa kwindawo apho kukho izinyithi ezinyibilikisiweyo kunye neegesi ezidliwayo.
2. Yiyiphi isondlo efunekayo kwiityhubhu zokukhusela i-silicon carbide?
Ukucoca rhoqo kunye nokufudumala kwangaphambili kunokuphucula ubomi babo, ngakumbi kwiindawo eziqhubekayo zokusetyenziswa. Ukugcinwa rhoqo kwendawo yonke imihla ye-30-40 kucetyiswa ukuba kulungiswe ukusebenza kakuhle.
3. Ngaba iityhubhu zokukhusela i-silicon carbide zingenziwa ngokwezifiso?
Ewe, ezi ityhubhu zifumaneka kwiindidi zobude kunye needayamitha kwaye zinokufakwa imisonto ye-NPT efakelweyo ukuze ilingane ukusetwa kwemizi-mveliso eyahlukeneyo.
Isishwankathelo, iityhubhu zokukhusela i-silicon carbide thermocouple zinika ukuqina, ukuchaneka, kunye nokumelana nokugqwala, okubenza babe yinxalenye engabalulekanga kumashishini aphezulu obushushu, aqhutywa ngokuchanekileyo.
