Ubushuhe ni iki?
Abashinzwe ubushyuhe bafite amazina atandukanye, nko guhinduranya ubushyuhe, kurinda ubushyuhe hamwe nubushakashatsi. Ukurikije ihame ryakazi, irashobora kugabanywa muburyo bwo gusimbuka ubwoko bwa thermostat, ubwoko bwamazi ya thermostat, ubwoko bwumuvuduko wa thermostat nubwoko bwa thermostat. Mubikoresho bigezweho byo kugenzura inganda, thermostat ya digitale nubwoko bukoreshwa cyane. Ukurikije imiterere, umugenzuzi wubushyuhe arashobora kugabanywamo ibice byubushyuhe hamwe nubushakashatsi bwubushyuhe.
Ubushuhe ni ubuhe?
Umubiri upima ubushyuhe ni ikintu gihindura ibimenyetso byubushyuhe mukimenyetso cyamashanyarazi, kandi mubisanzwe gishyirwa mubice byerekana ikintu cyagenzuwe kugirango gikurikirane agaciro kacyo. Mu rwego rwo kugenzura inganda, zikoreshwa cyane muri termometero zirimo thermocouples, résistoriste yumuriro, thermistors hamwe na sensor zidahuza. Muri byo, bitatu bya mbere ni uguhuza ibipimo bya termometero.
1. Thermocouple
Ihame ryo gupima ubushyuhe kuri thermocouples rishingiye ku ngaruka za Seebeck (ingaruka ya thermoelectric). Iyo ibyuma bibiri byibikoresho bitandukanye (mubisanzwe bitwara cyangwa semiconductor, nka platine-rhodium, nikel-chromium-nikel-silicon nibindi bikoresho bifatanije) bigira uruziga rufunze kandi bigashyira ubushyuhe butandukanye kumpande zombi zihuza, hakorwa ingufu za electromotive hagati ibyuma bibiri. Umuzingo nk'uwo witwa "thermocouple," mu gihe ibyo byuma byombi byitwa "electrode yumuriro," naho ingufu za elegitoronike zavuyemo zitwa "imbaraga za moteri ya termoelektrike." Thermocouples irangwa nubunini bwagutse bwo gupima ubushyuhe, ubushyuhe bwihuse bwumuriro, hamwe no kurwanya ihindagurika rikomeye.
2. Kurwanya ubushyuhe
Kurwanya ubushyuhe ni ikintu gihindura ibimenyetso byubushyuhe mukimenyetso cyamashanyarazi, kandi ihame ryakazi ryacyo rishingiye cyane cyane kubiranga impinduka zirwanya ibyuma hamwe nubushyuhe. By'umwihariko, abarwanya amashyuza bifashisha uyu mutungo wicyuma kugirango bapime ubushyuhe.
Mu kugenzura inganda, ubwoko bukoreshwa muburyo bwo kurwanya ubushyuhe burimo platine, umuringa na nikel. Muri byo, kurwanya platine nibyo bikunze kugaragara. Kurwanya ubushyuhe bifite ibiranga ubushyuhe bwiza buringaniye, imikorere ihamye hamwe nubusobanuro buhanitse mubushuhe busanzwe. Kubwibyo, mubisabwa mubushyuhe bwubushyuhe buringaniye, nta kunyeganyega hamwe nibisabwa bihanitse, ikoreshwa rya platine irwanya cyane.
3. Thermistor
Thermistor nikintu gihindura ibimenyetso byubushyuhe mukimenyetso cyamashanyarazi, kandi ihame ryakazi ryacyo rishingiye cyane cyane kubiranga imyuka ya semiconductor ihinduka hamwe nubushyuhe. By'umwihariko, thermistors yifashisha uyu mutungo wa semiconductor kugirango bapime ubushyuhe. Ugereranije nubushyuhe bwumuriro, ubukana bwa thermistor burahinduka cyane hamwe nihinduka ryubushyuhe, bityo igipimo cyacyo cyo gupima ubushyuhe ni gito (-50 ~ 350 ℃).
Thermistors igabanyijemo ibice bya NTC hamwe nubushyuhe bwa PTC. Ubushuhe bwa NTC bufite coefficient yubushyuhe bubi, kandi agaciro kabo ko kugabanuka kugabanuka uko ubushyuhe bwiyongera. Ubushyuhe bwa PTC bufite coefficient nziza yubushyuhe, kandi agaciro kayo ko kurwanya kaziyongera hamwe no kwiyongera kwubushyuhe. Bitewe nubushyuhe bwihariye bwo kurwanya ubushyuhe, thermistor ifite uburyo bwinshi bwo gukoresha mugushakisha ubushyuhe, kugenzura byikora, ibikoresho bya elegitoroniki nizindi nzego.
Zhuo Meng Shanghai Auto Co, Ltd. yiyemeje kugurisha MG & MAUXS ibice byimodoka ikaze kugura.
