Kodi chitofu cha gasi thermocouple ndi chiyani?

Ntchito yathermocouplechophikira mpweya ndichosewerera "Pansi pa moto wosazolowereka, mphamvu yamagetsi yamagetsi imatha, ndipo valavu yamagetsi yomwe ili payipi yamagesi imatseka gasi poyeserera kuti ipewe ngozi." Mukamagwiritsa ntchito bwino, mphamvu yamagetsi yamagetsi yamagetsi ikupitilira Onetsetsani kuti valavu yamagetsi yama payipi yamagalimoto imakhala yotseguka komanso yopuma mpweya nthawi zonse. Chida chotetezera moto cha thermocouple chimapangidwa ndithermocouplendi valavu ya solenoid. Kutentha kwa thermocouple kumatenthedwa kuti kutulutsa mphamvu zamagetsi, zomwe zimapangitsa kuti valavu ya solenoid ikhale yotseguka ndikuwotcha ndikuwotcha bwinobwino. Lawi litazimitsidwa modabwitsa, mphamvu yamagetsi yamagetsi imazimiririka ndipo valavu ya solenoid imatsekedwa moteteza. Udindo wa mbaula yamagetsi yamagetsi Yoyatsira mbaula yanyumba nthawi zambiri imakhala ndi singano yoyatsira moto komanso singano yoteteza moto wamoto. Thermocouple ndi gawo lofunikira kwambiri pachitofu cha gasi. Mtundu wa thermocouple umakhudzana ndi nthawi yoyatsira poyatsira komanso poyatsira bwino mbaula. Thermocouple kwenikweni ndi mtundu wazinthu zotentha, zimayesa kutentha, ndikusintha chizindikiro cha kutentha kukhala chizindikiro champhamvu yamagetsi, yomwe imasandulika kutentha kwa sing'anga poyesa chida chamagetsi. Thermocouple imapangidwa ndi zida ziwiri zosiyana. Zipangizo zosiyanasiyana za alloy zimatulutsa mphamvu zamagetsi zamagetsi zosiyanasiyana pansi pa kutentha, ndipo ma thermocouples amapangidwa pogwiritsa ntchito ma thermoelectric osiyanasiyana opangidwa ndi zida zosiyanasiyana za aloyi chifukwa cha kutentha. Makondakitala awiri azigawo zosiyanasiyana amalumikizidwa ndi dera lamagawo onse kumapeto. Pamene kutentha kwa mphambano kumakhala kosiyana, mphamvu yamagetsi yamagetsi ipangika mdera. Chodabwitsachi chimatchedwa mphamvu yamagetsi, ndipo mphamvu yamagetsi yamagetsi iyi imatchedwa mphamvu yamagetsi. Thermocouples amagwiritsa ntchito mfundoyi kuyeza kutentha. Mwa iwo, malekezero ena omwe amagwiritsidwa ntchito poyesa kutentha kwa sing'anga amatchedwa kumapeto kwa magwiridwe antchito, ndipo mathero ena amatchedwa ozizira; kumapeto kozizira kumalumikizidwa ndi chida chowonetsera kapena chida chothandizira, ndipo chida chowonetsera chikuwonetsa kutentha komwe kumapangidwa ndi thermocouple. Mphamvu yamagetsi. Kutalika kwathermocoupleiyenera kukhala yofanana ndendende ndi kutalika kwa chivundikiro chamoto, ndipo chisamaliro chiyenera kuchitidwa kuti mtunda pakati pathermocouplendi chivundikiro chamoto. Mtunda wapakati pa thermocouple ndi chivundikiro cha lawi sayenera kukhala patali kwambiri, nthawi yayitali kwambiri ndi 4 ± 0.5mm. Ngati malo oyikirako ndi otsika kwambiri, thermocouple sidzakhala yotenthedwa mokwanira, ndipo mphamvu yamagetsi yamagetsi sikhala yokwanira, ndi valavu ya solenoid sidzakopeka, ndipo malo oyikirako azikhala okwera kwambiri, Kulumikizana ndi lawi kuli kwakukulu kwambiri, ndikosavuta kutentha thermocouple, chifukwa chomwechi, kutali kwambiri, kuthekera kwamagetsi sikungakhale kokwanira, sikungapangitse valavu ya solenoid kukopa.
