Kodi thermostat ndi chiyani?
Olamulira oyendetsa kutentha ali ndi mayina osiyanasiyana, monga kutentha kwa kutentha, matenthedwe otentha ndi kutentha kwa kutentha. Malinga ndi mfundo yogwira ntchito, imatha kugawidwa kuti mulumphe tepile marrmostat, mtundu wa madzimadzi matermostat, kukakamiza mtundu wa thermostat ndi mtundu wamagetsi thermostat. Mu zida zamakono zamakono za mafakitale, mawonekedwe a digito ndiye mtundu womwe umagwiritsidwa ntchito kwambiri. Malinga ndi kapangidwe kake, wowongolera kutentha amatha kugawidwa kukhala kutentha kwa owongolera kutentha komanso wowongolera kutentha.
Kodi ma thermometer ndi ati?
Kuchepetsa kutentha kwa thupi ndi gawo lomwe limasinthira kusaina mu chizindikiro chamagetsi, ndipo nthawi zambiri amaikidwa mu chizindikiritso cha chinthu cholamulidwa kuti uyang'anire mtengo wake. Pamunda wa kuwongolera mafakitale, nthawi zambiri ma thermometers amagwiritsa ntchito ma thermocouroucs, matenthedwe ndi ma hermal ndi masensa olumikizana. Pakati pawo, atatu oyamba amalumikizana ndi ma thermometers.
1. Thermocouple
Mfundo yofananira kwa kutentha kwa thermocourouves imakhazikika pa exbeck zotsatira (thermoelertric zotsatira). Pamene zitsulo ziwiri za zinthu zosiyanasiyana (nthawi zambiri zimachititsa kapena semicmictors, monga plaminium-rickel-cromium-sicket ndi zida zina zolumikizidwa pakati pa zitsulo ziwiri. Chipilala choterechi chimatchedwa "Thermocouple," pomwe zitsulo ziwirizi zimatchedwa "masitima a matenthedwe," ndipo chifukwa cha zamagetsi zimatchedwa "a thermoelectric mphamvu." Thermocouct imadziwika ndi kutentha kwawo kwakukulu, kuyankha kwachangu, komanso kukana mphamvu kwambiri.
2. Kutsutsa kwamafuta
Kukana kwa mafuta ndi gawo lomwe limasandutsa chizindikiro cham'madzi kukhala chizindikiro chamagetsi, ndipo mfundo yake yogwira ntchito imakhazikitsidwa ndi machitidwe a zitsulo kukana ndi kutentha. Makamaka, kutentha kwa mafuta kumathandizanso kugwiritsa ntchito malowa achitsulo kuti muyeze kutentha.
Makamaka, mitundu yomwe imagwiritsidwa ntchito kawirikawiri yogwirira ntchito mafuta imaphatikizapo Plaginim, mkuwa ndi Nickel. Pakati pawo, kukana platinamu ndikofala kwambiri. Kutsutsana kwa mafuta kumakhala ndi mawonekedwe abwinobwino kutentha kwa malo, magwiridwe okhazikika komanso kuwongolera kwambiri m'munda wa kutentha kwabwinobwino. Chifukwa chake, pogwiritsira ntchito kutentha pang'ono, palibe kugwedezeka ndi zofunikira kwambiri, kugwiritsa ntchito kukana platinam nthawi zambiri kumakonda.
3. Thermartor
Thermaristor ndi gawo lomwe limasinthira kusaina ndi chizindikiro chamagetsi, ndipo mfundo yake yogwira ntchito imakhazikitsidwa ndi mikhalidwe ya kukana kwa Semiconductor kusinthira ndi kutentha. Makamaka, owonda amapezerapo mwayi pa malo awa a semiconductors kuti muyeze kutentha. Poyerekeza ndi kuchuluka kwa mafuta, kukana kwa thermaristor kumasintha kwambiri ndikusintha kwa kutentha, kotero kutentha kwake kumakhala kofunikira (-50 ~ 350 ℃).
Otsatsa agawidwa mu NTC Thermars ndi PTC Thermars. NTC Thermars ali ndi kutentha kosavuta, ndipo njira yawo yolimbana ndi kutentha imatsirizitsa. PTC Thermaristor ali ndi kutentha kwabwino, ndipo mtengo wokana kukana ukukulira ndikuwonjezeka kwa kutentha. Chifukwa cha kutentha kwake kwina, Thermaristror ali ndi ntchito zingapo podzitchinjiriza, kuwongolera kokha, zida zamagetsi ndi minda ina.
