Menene thermocouple na gas?

Aiki nathermocouplena tukunyar gas shine a yi wasa "A ƙarƙashin yanayin yanayin zafi mara kyau, ƙarfin wutar lantarki na thermocouple ya ɓace, kuma bawul ɗin solenoid akan bututun iskar gas yana kashe iskar gas a ƙarƙashin aikin bazara don guje wa haɗari." A lokacin amfani na yau da kullun, ƙarfin thermoelectric na thermocouple yana ci gaba Tabbatar cewa bawul ɗin solenoid na bututun iskar gas koyaushe yana buɗewa kuma yana samun iska. Thermocouple flameout kariya na'urar ya ƙunshi athermocoupleda solenoid bawul. The ignition thermocouple yana mai zafi don samar da yuwuwar thermoelectric, wanda ke sa bawul ɗin solenoid ya buɗe kuma ya ba da iska kuma yana ƙone kullum. Lokacin da harshen wuta ya ƙare, ƙarfin wutar lantarki na thermocouple ya ɓace kuma bawul ɗin solenoid yana rufe kariya. Matsayin murhun gas ɗin thermocouple Mai ƙona murhun iskar gas yawanci ana sanye da allura mai kunna wuta da allurar kariya daga zafin wuta. Thermocouple wani muhimmin bangare ne na murhun gas. Ingancin thermocouple yana da alaƙa da lokacin amsawar kunnawa da ƙimar nasarar ƙonewar murhun gas. The thermocouple a haƙiƙa wani nau'i ne na gano yanayin zafin jiki, yana auna zafin jiki kai tsaye, kuma yana canza siginar zafin jiki zuwa siginar ƙarfin thermoelectromotive, wanda ake juyar da shi zuwa yanayin zafin matsakaicin matsakaici ta kayan aikin lantarki. Thermocouple ya ƙunshi kayan gami guda biyu daban-daban. Daban-daban kayan gami za su samar da nau'ikan ma'aunin zafin jiki daban-daban a ƙarƙashin aikin zafin jiki, kuma ana kera ma'aunin zafi da sanyio ta hanyar amfani da ma'aunin zafin jiki daban-daban waɗanda kayan gami daban-daban ke samarwa a ƙarƙashin aikin zafin jiki. Ana haɗa madugu biyu na sassa daban-daban zuwa da'ira mai haɗaka a ƙarshen duka. Lokacin da zafin mahaɗin ya bambanta, za a samar da ƙarfin lantarki a cikin kewaye. Wannan al'amari shi ake kira da thermoelectric sakamako, kuma wannan electromotive karfi da ake kira thermoelectric m. Thermocouples suna amfani da wannan ka'ida don auna zafin jiki. Daga cikin su, wannan ƙarshen da ake amfani da shi kai tsaye don auna zafin matsakaici ana kiransa ƙarshen aiki, ɗayan kuma ana kiransa ƙarshen sanyi; an haɗa ƙarshen sanyi zuwa kayan aikin nuni ko kayan tallafi, kuma kayan aikin nuni zai nuna yanayin zafin da thermocouple ya haifar. Matsalolin thermoelectric. Tsayin dathermocoupleya kamata ya zama daidai da tsayin murfin wuta, kuma ya kamata a kula don kiyaye nisa tsakaninthermocoupleda murfin wuta. Nisa tsakanin thermocouple da murfin harshen wuta kada yayi nisa, gabaɗaya mafi kyawun nisan shine 4 ± 0.5mm. Idan matsayin shigarwa yayi ƙasa da ƙasa, thermocouple ba zai yi zafi sosai ba, kuma ƙarfin wutar lantarki ba zai isa ba, kuma ba za a ja hankalin bawul ɗin ba, kuma matsayin shigarwa zai yi yawa, Lambar wutar tana da yawa, yana da sauƙi don ƙona thermocouple, dalili ɗaya, yayi nisa, ƙarfin thermoelectric ba zai isa ba, ba zai sa bawul ɗin solenoid ya jawo hankali ba.
