Mfundo yogwira ntchito ya thermocouple

Zosakaniza ziwiri zosiyana za kondakitala (wotchedwa thermocouple waya kapena electrode yotentha) kaphatikizidwe kaphatikizidwe kumapeto onse awiri, pamene kutentha kwapakati sikuli nthawi imodzi, m'derali amapanga mphamvu ya electromotive, chodabwitsa ichi chotchedwa thermoelectric effect, ndi electromotive mphamvu yotchedwa thermoelectric potential.Thermocouple ndi kugwiritsa ntchito mfundo ya kuyeza kutentha, amene mwachindunji ntchito kuyeza sing'anga kutentha amatchedwa ntchito kumapeto kwa mapeto (amadziwikanso kuti kuyeza mbali), mapeto ena amatchedwa ozizira mapeto (amadziwikanso kuti chipukuta misozi). ;Mapeto ozizira olumikizidwa ndi chida chowonetsera kapena mita, chida chowonetsera chidzawonetsa kuthekera kwa thermocouple thermoelectric.

Thermocouple kwenikweni ndi mtundu wa mphamvu converter, izo otembenuka kutentha kukhala magetsi, ntchito mphamvu thermoelectric kwaiye ndi kutentha kuyeza, chifukwa thermocouple mphamvu thermoelectric, ayenera kulabadira mafunso otsatirawa:

1, mphamvu ya thermocouple thermoelectric mu kutentha kwa thermocouple kumbali zonse ziwiri za ntchitoyo ntchitoyo ndi yosauka, osati kuzizira kwa thermocouple ndi ntchito, kusiyana kwa kutentha pa malekezero onse a ntchito;

2, kukula kwa thermocouple thermoelectric mphamvu opangidwa ndi, pamene zinthu yunifolomu thermocouple, alibe chochita ndi kutalika ndi awiri a thermocouple, ndipo kokha pa malekezero a thermocouple zinthu zikuchokera ndi kusiyana kutentha;

3, pamene awiri thermocouple waya thermocouple zinthu zikuchokera anatsimikiza, kukula kwa thermocouple mphamvu thermoelectric, kokha zokhudzana ndi kusiyana thermocouple kutentha;Ngati kutentha kwa thermocouple kumathera kuzizira, izi mu mphamvu ya thermocouple thermoelectric ndi mathero a ntchito imodzi yokha ya kutentha.Zida ziwiri zosiyana zowotcherera Kokondakita kapena semi-conductor A ndi B, zimapanga lupu A lotsekeka, monga momwe zasonyezedwera.Pamene wochititsa A ndi B awiri kulimbikira mfundo kutentha kusiyana pakati 1 ndi 2, kumachitika pakati pa mphamvu electromotive, motero kupanga kukula kwa A panopa mu dera.Thermocouple ikugwiritsa ntchito izi kuti igwire ntchito.
