Silicon carbide thermocouple chitetezo chubu
Silicon Carbide Thermocouple Protection Tube: High-Performance Shield for Extreme Conditions
Kodi Ubwino Wotani wa Silicon Carbide Thermocouple Protection Tubes?
Silicon carbide thermocouple chitetezo machubu, zomwe zimadziwika kuti zimakhala zolimba kwambiri komanso zimakhala zogwira ntchito, ndizofunikira pamapulogalamu omwe amafunikira kulondola kwa kutentha kwapamwamba komanso kupirira. Pokhala ndi kukana kutentha kwambiri mpaka 1550 ° C (2800 ° F), machubu a silicon carbide amatchinjiriza bwino ma thermocouples kumadera ovuta, kuwonetsetsa kulondola m'mafakitale monga kusungunuka kwa aluminiyamu, zitsulo, ndi zoumba. Zapadera za silicon carbide zimathandizanso kuti zisawonongeke ndi okosijeni, dzimbiri, ndi kutentha kwa kutentha - makhalidwe omwe amaposa zipangizo zamakono monga aluminiyamu ndi graphite mu ntchito zinazake.
Chifukwa Chiyani Musankhe Silicon Carbide Kuti Muteteze Thermocouple?
Silicon carbide, zida zaumisiri zolimba zokhala ndi matenthedwe apamwamba komanso kukana kwapadera kumavalidwe amankhwala, zimapereka chitetezo champhamvu kuzitsulo zosungunuka monga aluminiyamu ndi zinki. Izi ndi zomwe zimapangitsa kuti ziwonekere:
- High Thermal Conductivity: Silicon carbide yabwino kwambiri matenthedwe matenthedwe matenthedwe amaonetsetsa kutentha kwachangu, kuwongolera kutentha komanso kulondola pakugwiritsa ntchito nthawi yeniyeni.
- Oxidation ndi Corrosion Resistance: Zinthuzo zimakhala zokhazikika ngakhale zitakhala ndi mpweya wowononga kapena zitsulo zosungunuka, kuteteza ma thermocouples kuti asawonongeke ndikutalikitsa moyo wawo.
- Low Porosity: Ndi mulingo wa porosity mozungulira 8%, machubu a silicon carbide thermocouple amalepheretsa kuipitsidwa ndikusunga umphumphu wapamwamba pa kutentha kosalekeza
Zofunika Kwambiri ndi Mapulogalamu
| Mbali | Kufotokozera |
|---|---|
| Kutentha Kusiyanasiyana | Kufikira 1550°C (2800°F) |
| Thermal Shock Resistance | Zabwino kwambiri pakusintha kutentha mwachangu |
| Chemical Kukhazikika | Kugonjetsedwa ndi zidulo, alkalis, ndi slag |
| Zakuthupi | Isostatic mbande silicon carbide |
| Porosity | Otsika (8%), akuwongolera kulimba |
| Makulidwe Opezeka | Kutalika 12 "mpaka 48"; 2.0" OD, zolumikizira za NPT zilipo |
Machubuwa amagwiritsidwa ntchito kwambiri m'ng'anjo zotentha kwambiri ndi ng'anjo zosungunuka za aluminiyamu, komwe kunyowa kwawo kochepa ndi aluminiyumu yosungunuka kumathandiza kuchepetsa kufunika kokonza pafupipafupi. Kuphatikiza apo, kulimba kwa silicon carbide komanso kukana kuvala kumapangitsa kuti ikhale chisankho chabwino kwambiri pantchito yotalikirapo m'mafakitale ndi ng'anjo zamafuta, komwe imalepheretsa kuukira kwa slag ndi okosijeni.
Mafunso Ofunsidwa Kawirikawiri (FAQ)
1. Kodi silicon carbide ikufananiza bwanji ndi zida zina zoteteza chubu?
Silicon carbide imaposa alumina ndi zida zina zadothi pakugwiritsa ntchito kutentha kwambiri chifukwa cha kukana kwake kwa kutentha komanso kukhazikika kwa okosijeni. Ngakhale onse aluminiyamu ndi silicon carbide amatha kupirira kutentha kwambiri, silicon carbide imapambana m'malo omwe zitsulo zosungunuka ndi mpweya wowononga zimakhala.
2. Ndi kukonza kotani komwe kumafunikira pa machubu oteteza silicon carbide?
Kuyeretsa nthawi zonse ndi kutentha kungathe kuonjezera moyo wawo, makamaka m'malo ogwiritsidwa ntchito mosalekeza. Kukonza pamwamba pafupipafupi masiku 30-40 kumalimbikitsidwa kuti muwongolere magwiridwe antchito.
3. Kodi machubu oteteza silicon carbide angasinthidwe makonda?
Inde, machubuwa amapezeka muutali ndi mainchesi osiyanasiyana ndipo amatha kukhala ndi zida za NPT zaulusi kuti zigwirizane ndi mafakitole osiyanasiyana.
Mwachidule, machubu oteteza silicon carbide thermocouple amapereka kukhazikika, kulondola, komanso kukana dzimbiri, zomwe zimawapangitsa kukhala gawo lofunika kwambiri m'mafakitale otentha kwambiri, oyendetsedwa bwino.
