Ama-thermocouple aphakathi kwezinzwa zokushisa ezisetshenziswa kakhulu ezimbonini ezifana nokukhiqiza, i-HVAC, izimoto, izindiza kanye nokucubungula ukudla. Umbuzo ovamile ovela konjiniyela kanye nochwepheshe uthi: Ingabe ama-thermocouple adinga ucingo olukhethekile? Impendulo inguyebo ozwakalayo—ama-thermocouple kumele axhunywe nohlobo olufanele lwentambo ukuqinisekisa ukulinganiswa kokushisa okunembile nokuthembekile.
Kungani Ama-Thermocouple Edinga Intambo Ekhethekile
Ama-thermocouple asebenza ngokusekelwe kumphumela we-Seebeck, lapho izinsimbi ezimbili ezingafani zikhiqiza i-voltage encane (ngama-millivolts) ngokulingana nomehluko wokushisa phakathi kwe-junction yokulinganisa (i-hot end) kanye ne-reference junction (i-cold end). Le voltage ibucayi kakhulu, futhi noma yikuphi ukuphambuka ekwakhiweni kwentambo kungaletha amaphutha.
Izizathu Eziyinhloko Zokuthi Kungani Intambo Kagesi Ejwayelekile Ingasebenzi
1. Ukuhambisana kwezinto ezibonakalayo
- Ama-thermocouple enziwe ngamabhangqa ensimbi athile (isb.Uhlobo Kisebenzisa i-Chromel ne-Alumel,Uhlobo Jisebenzisa i-Iron ne-Constantan).
- Ukusebenzisa ucingo lwethusi olujwayelekile kungaphazamisa isekethe ye-thermoelectric, okuholela ekufundweni okungalungile.
2. Ukumelana Nokushisa
- Ama-thermocouple avame ukusebenza emazingeni okushisa aphezulu kakhulu (kusukela ku-200°C kuya ngaphezu kuka-2300°C, kuye ngohlobo).
- Izintambo ezijwayelekile zingase zincibilike, zonakale, noma zincibilike ngaphansi kokushisa okukhulu, okubangela ukuzulazula noma ukwehluleka kwesignali.
3. Ubuqotho Besignali Nokumelana Nomsindo
- Izimpawu ze-Thermocouple zisebangeni le-millivolt, okwenza zibe sengozini yokuphazamiseka kwe-electromagnetic (EMI).
- Intambo efanele ye-thermocouple ifaka phakathi ukuvikela (isb., ukuvikela okulukiwe noma i-foil) ukuvimbela umsindo ekuphazamiseni ukufundwa.
4. Ukunemba Kokulinganisa
- Uhlobo ngalunye lwe-thermocouple (J, K, T, E, njll.) lune-voltage-temperature curve ejwayelekile.
- Ukusebenzisa ucingo olungalingani kushintsha lobu budlelwano, okuholela emaphutheni okulinganisa kanye nedatha engathembekile.
Izinhlobo Zezintambo Ze-Thermocouple
Kunezinhlobo ezimbili eziyinhloko zentambo ye-thermocouple:
1. Ucingo Lokunweba
- Yenziwe ngama-alloy afanayo ne-thermocouple uqobo (isb., intambo yokwandisa yohlobo lwe-K isebenzisa i-Chromel ne-Alumel).
- Kusetshenziswa ukwelula isignali ye-thermocouple emabangeni amade ngaphandle kokufaka amaphutha.
- Ngokuvamile kusetshenziswa ezindaweni ezinokushisa okumaphakathi (njengoba ukushisa okuphezulu kungathikameza ukufudumala).
2. Ucingo Olukhokhelayo
- Kwenziwe ngezinto ezahlukene kodwa ezifanayo ngokwe-thermoelectric (ngokuvamile ezingabizi kakhulu kune-thermocouple alloys emsulwa).
- Yakhelwe ukufanisa umphumela we-thermocouple emazingeni okushisa aphansi (ngokuvamile ngaphansi kuka-200°C).
- Isetshenziswa kakhulu kumaphaneli okulawula kanye nezinsimbi lapho ukushisa okukhulu kungeyona inkinga.
Zombili izinhlobo kumele zihambisane nezindinganiso zemboni (ANSI/ASTM, IEC) ukuqinisekisa ukuvumelana nokusebenza kahle.
Ukukhetha Intambo Efanele Ye-Thermocouple
Uma ukhetha ucingo lwe-thermocouple, cabanga ngalokhu:
- Uhlobo lwe-Thermocouple (K, J, T, E, njll.) – Kumelwe lufane nohlobo lwenzwa.
- Izinga Lokushisa - Qinisekisa ukuthi ucingo luyakwazi ukusingatha izimo zokusebenza ezilindelekile.
- Izinto Zokuvikela – I-Fiberglass, i-PTFE, noma i-ceramic insulation yokusetshenziswa kokushisa okuphezulu.
- Izidingo Zokuvikela – Ukuvikela okulukiwe noma okwenziwe ngefoyili ukuze kuvikelwe i-EMI ezindaweni zezimboni.
- Ukuguquguquka Nokuqina – Ucingo oluhlanganisiwe lokugoba okuqinile, umongo oqinile wokufakwa okuqinile.
Izixazululo Zethu Zezintambo Ze-Thermocouple Ezisezingeni Eliphezulu
KwaTankii, sihlinzeka ngentambo ye-thermocouple yekhwalithi ephezulu eyenzelwe ukunemba, ukuqina, kanye nokuthembeka. Imikhiqizo yethu ifaka:
- Izinhlobo Eziningi Ze-Thermocouple (K, J, T, E, N, R, S, B) – Iyahambisana nazo zonke izindinganiso ezinkulu ze-thermocouple.
- Izinketho Ezivikela Izinga Lokushisa Eliphezulu Nokumelana Nokugqwala – Zilungele izindawo zezimboni ezinzima.
- Izinhlobo Ezivikelwe Futhi Ezifakwe Ukushisa – Nciphisa ukuphazamiseka kwesignali ukuze kufundwe kahle.
