Yintoni i-thermostat?
Abalawuli bobushushu baneentlobo ngeentlobo zamagama, njengeeswitshi zokulawula ubushushu, abakhuseli bobushushu kunye nabalawuli bobushushu. Ngokomgaqo osebenzayo, inokwahlulwahlulwa ibe yi-thermostat yohlobo lwe-jump, i-thermostat yohlobo lwe-liquid, i-thermostat yohlobo loxinzelelo kunye ne-thermostat yohlobo lwe-elektroniki. Kwizixhobo zolawulo lwemizi-mveliso zanamhlanje, i-thermostat yedijithali lolona hlobo lusetyenziswa kakhulu. Ngokwesakhiwo, isilawuli sobushushu sinokwahlulwa sibe yi-controller yobushushu edibeneyo kunye ne-controller yobushushu yemodyuli.
Zithini ii-thermometers?
Umzimba wokulinganisa ubushushu yinxalenye eguqula isignali yobushushu ibe sisignali yombane, kwaye idla ngokufakwa kwindawo yokufumanisa into elawulwayo ukuze ijonge ixabiso layo lobushushu. Kwicandelo lolawulo lwemizi-mveliso, ii-thermometers ezisetyenziswa rhoqo ziquka ii-thermocouples, ii-thermal resistors, ii-thermistors kunye nee-non-contact sensors. Phakathi kwazo, ezintathu zokuqala zii-contact thermometers.
1. I-thermocouple
Umgaqo wokulinganisa ubushushu kwii-thermocouples usekelwe kwisiphumo seSeebeck (isiphumo se-thermoelectric). Xa iintsimbi ezimbini ezenziwe ngezinto ezahlukeneyo (ngokuqhelekileyo ii-conductors okanye ii-semiconductors, ezifana ne-platinum-rhodium, i-nickel-chromium-nickel-silicon kunye nezinye izinto ezidityanisiweyo) zenza i-loop evaliweyo kwaye zisebenzise ubushushu obahlukeneyo kwiziphelo zazo ezimbini zokudibanisa, amandla e-electromotive aveliswa phakathi kweentsimbi ezimbini. I-loop enjalo ibizwa ngokuba yi-"thermocouple," ngelixa ezi metals zimbini zibizwa ngokuba yi-"thermal electrode," kwaye amandla e-electromotive avelayo abizwa ngokuba yi-"thermoelectric motivation force." Ii-thermocouples zibonakaliswa luluhlu lwazo olubanzi lokulinganisa ubushushu, impendulo ekhawulezayo yobushushu, kunye nokumelana okunamandla kokungcangcazela.
2. Ukumelana nobushushu
Ukumelana nobushushu yinxalenye eguqula isignali yobushushu ibe sisignali yombane, kwaye umgaqo wayo wokusebenza usekelwe kakhulu kwiimpawu zokutshintsha kokumelana nesinyithi ngobushushu. Ngokukodwa, ii-resistors zobushushu zisebenzisa olu phawu lwesinyithi ukulinganisa ubushushu.
Kulawulo lwemizi-mveliso, iintlobo ezisetyenziswa kakhulu zokumelana nobushushu ziquka iplatinum, ithusi kunye ne-nickel. Phakathi kwazo, ukumelana neplatinum yeyona ixhaphakileyo. Ukumelana nobushushu kuneempawu zokulingana kakuhle kobushushu, ukusebenza okuzinzileyo kunye nokuchaneka okuphezulu kwicandelo lobushushu obuqhelekileyo. Ke ngoko, kwimeko yokusetyenziswa kobushushu obuphakathi, akukho kungcangcazela kunye neemfuno zokuchaneka okuphezulu, ukusetyenziswa kokumelana neplatinum kudla ngokukhethwa.
3. I-Thermistor
I-thermistor yinxalenye eguqula isignali yobushushu ibe sisignali yombane, kwaye umgaqo wayo wokusebenza usekelwe kakhulu kwiimpawu zokumelana kwe-semiconductor ezitshintsha ngobushushu. Ngokukodwa, ii-thermistors zisebenzisa eli lungelo lee-semiconductors ukulinganisa ubushushu. Xa kuthelekiswa nokumelana nobushushu, ukumelana kwe-thermistor kutshintsha kakhulu ngokutshintsha kobushushu, ngoko ke uluhlu lwayo lokulinganisa ubushushu luncinci (-50~350℃).
Iithermistors zahlulwe ngee-thermistors ze-NTC kunye nee-thermistors ze-PTC. Iithermistors ze-NTC zine-coefficient yobushushu engalunganga, kwaye ixabiso lazo lokumelana liyehla njengoko ubushushu busanda. I-PTC thermistor ine-coefficient yobushushu echanekileyo, kwaye ixabiso layo lokumelana liya kwanda ngokunyuka kobushushu. Ngenxa yeempawu zayo zobushushu ezichaseneyo, i-thermistor ineendlela ezahlukeneyo zokusetyenziswa ekufumaneni ubushushu, ulawulo oluzenzekelayo, izixhobo ze-elektroniki kunye nezinye iinkalo.
I-Zhuo Meng Shanghai Auto Co., Ltd. izimisele ukuthengisa iinxalenye zeemoto ze-MG&MAUXS kwaye wamkelekile ukuzithenga.
