Iyini ukugoba kwe-thermostat yemoto
Ukugoba kwe-thermostat yemoto kuyisimo esenza ukuthi i-thermostat igxumeke ngaphansi kwethonya lokwanda nokufinyela kwe-thermal. Ama-thermostat ngokuvamile enziwa ngamashidi amancane ensimbi. Lapho kushisa, ishidi lensimbi lizogotshwa ukushisa. Lokhu kugoba kudluliselwa koxhumana nabo be-thermostat ngokuqhutshwa kokushisa, ngaleyo ndlela kukhiqiza izinga lokushisa elizinzile .
Isebenza kanjani i-thermostat
I-thermostat isebenzisa into yokushisisa kagesi ukushisa ishidi lensimbi, ibangele ukuthi lishise futhi ligotshwe. Lokhu kugoba kudluliselwa ngokuqhutshwa kokushisa koxhumana nabo be-thermostat, okuholela ekukhishweni kwezinga lokushisa okuzinzile. Lesi senzo sokugoba ngaphansi kokushisa saziwa ngokuthi "umphumela wokushisa othize", okuwukunwebeka okungokwemvelo nokufinyela kwento ethile phakathi nokushisa noma ukupholisa .
Uhlobo lwe-thermostat
Kunezinhlobo ezintathu eziyinhloko zama-thermostats ezimoto: i-bellows, amashidi e-bimetal kanye ne-thermistor. Uhlobo ngalunye lwe-thermostat lunezimiso zalo zokusebenza ezithile nezimo zohlelo lokusebenza:
Bellows : Izinga lokushisa lilawulwa ukuguquguquka kwesivunguvungu lapho izinga lokushisa lishintsha.
Ishidi le-bimetallic : kusetshenziswa inhlanganisela yamashidi amabili ensimbi anama-coefficients ahlukene okunweba okushisayo, isifunda silawulwa ngokugoba lapho izinga lokushisa lishintsha.
I-thermistor : Inani lokumelana liyashintsha nezinga lokushisa ukuze lilawule isekethe ivuleke noma ivale.
Isimo sohlelo lokusebenza lwe-thermostat
I-Thermostat isetshenziswa kakhulu ohlelweni lwe-air conditioning yezimoto, umsebenzi oyinhloko ukuzwa izinga lokushisa elingaphezulu kwe-evaporator, ukuze ulawule ukuvulwa nokuvala kwe-compressor. Lapho izinga lokushisa ngaphakathi kwemoto lifinyelela inani elimisiwe, i-thermostat izoqala i-compressor ukuqinisekisa ukuthi umoya ugeleza kahle ku-evaporator ukugwema isithwathwa; Lapho izinga lokushisa lehla, i-thermostat ivala i-compressor, igcine izinga lokushisa ngaphakathi kwemoto lilingana .
Umsebenzi we-thermostat ukushintsha indlela yokujikeleza kwesipholile. Izimoto eziningi zisebenzisa izinjini ezipholiswe ngamanzi, eziqeda ukushisa ngokujikeleza okuqhubekayo kwesipholile enjinini. Isipholile enjinini sinezindlela ezimbili zokujikeleza, eyodwa ingumjikelezo omkhulu kanti enye ingumjikelezo omncane.
Lapho injini iqala nje, ukujikeleza kwe-coolant kuncane, futhi into epholile ngeke isuse ukushisa nge-radiator, evumela ukufudumala okusheshayo kwenjini. Lapho injini ifinyelela izinga lokushisa elivamile lokusebenza, isipholile sizosakazwa futhi sihlakazwe nge-radiator. I-thermostat ingashintsha indlela yomjikelezo ngokuya ngezinga lokushisa lesipholile, ngaleyo ndlela ithuthukise ukusebenza kahle kwenjini.
Uma injini iqala, uma into epholile kade izungeza, lokho kuzoholela ekwenyukeni kancane kancane kwezinga lokushisa lenjini, namandla enjini azoba ntekenteke futhi ukusetshenziswa kukaphethiloli kuzoba phezulu. Futhi uhla oluncane lokupholisa okujikelezayo lungathuthukisa izinga lokushisa kwenjini.
Uma i-thermostat yonakele, izinga lokushisa lamanzi enjini lingase libe phezulu kakhulu. Ngenxa yokuthi isipholile singahlala sijikeleza kancane futhi singakushisi ukushisa ngerediyetha, izinga lokushisa lamanzi lizokhuphuka.
Ngamafuphi, indima ye-thermostat ukulawula indlela yokujikeleza kwesipholile, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kwenjini futhi kugwenywe izinga lokushisa lamanzi eleqile. Uma uhlangabezana nezinkinga zemoto, cabanga ukuhlola ukuthi i-thermostat isebenza kahle yini.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko kule sayithi!
