Yini i-car thermostat egoba
Ukudonswa kwe-thermostat yezimoto yinto eyenzeka yi-thermostat deform engaphansi kwethonya lokwanda okushisayo kanye nokuwohloka. Ama-thermostats ajwayele ukwenziwa ngamashidi amancanyana ensimbi. Lapho kufuthelwa, ishidi lensimbi lizogoba ngokushisa. Lokhu kugoba kudluliselwa koxhumana nabo be-thermostat ngokushisa, ngaleyo ndlela kukhiqize izinga lokushisa elizinzile.
I-thermostat isebenza kanjani
I-thermostat isebenzisa into yokushisa kagesi ukushisa ishidi lensimbi, okwenza kube ukufudumala futhi kugobeke. Lokhu kugoba kudluliselwa ngokushisa koxhumana nabo ekushiseni koxhumana nabo be-thermostat, okuholela ekuphumeni kokushisa okuzinzile. Le nto yokugoba ngaphansi kokushisa yaziwa ngokuthi "umphumela othize wokushisa", okungukunwetshwa kwemvelo nokugxekwa kokuqukethwe ngesikhathi sokushisa noma ukupholisa.
Uhlobo lwe-thermostat
Kunezindlela ezintathu eziphambili zama-thermostats wezimoto: ama-bellows, amashidi e-bimetal kanye ne-thermistor. Uhlobo ngalunye lwe-thermostat lunezimiso zalo ezithile zokusebenza kanye nezimo zohlelo lokusebenza:
Ama-Bellows: Izinga lokushisa lilawulwa yi-deformation of the bellews lapho izinga lokushisa lishintsha.
Ishidi le-Bimetallic: Kusetshenziswa inhlanganisela yamashidi amabili wensimbi ane-coefficients ehlukene ye-thermal, umjikelezo alawulwa ngokugoba lapho izinga lokushisa lishintsha.
I-Thermistor: Inani lokumelana lishintsha ngokushisa ukuze lilawule umjikelezo futhi livaliwe.
Isimo sesicelo se-thermostat
I-Thermostat isetshenziswa kabanzi kuhlelo lwezimo zemoto ezimoyeni, umsebenzi oyinhloko ukuzwa ukushisa komhlaba we-evaporator, ukuze ulawule ukuvulwa kwe-compressor nokuvala. Lapho amazinga okushisa ngaphakathi emotweni efinyelela inani esethiwe, i-thermostat izoqala i-compressor ukuze iqinisekise ukuthi umoya ugeleza kahle ngokusebenzisa i-evaporator ukugwema isithwathwa; Lapho amazinga okushisa ehla, i-thermostat icisha i-compressor, ukugcina izinga lokushisa ngaphakathi kwemoto lilinganise.
Umsebenzi we-thermostat ukushintsha indlela yokujikeleza ye-coolant. Izimoto eziningi zisebenzisa izinjini ezipholile zamanzi, eziqeda ukushisa ngokujikeleza okuqhubekayo kwe-coolant enjini. I-Coolant enjini inezindlela ezimbili zokujikeleza, eyodwa ngumjikelezo omkhulu futhi eyodwa umjikelezo omncane.
Lapho injini iqala nje, ukujikeleza okupholile kuncane, futhi okupholile ngeke kunciphise ukushisa nge-radiator, okulungele ukufudumala okusheshayo kwenjini. Lapho injini ifinyelela emazingeni okushisa ajwayelekile okusebenza, okupholile kuzosakazwa futhi kuhlakazeke nge-radiator. I-thermostat ingashintsha indlela yomjikelezo ngokusho kokushisa kwe-coolant, ngaleyo ndlela ithuthukise ukusebenza kahle kwenjini.
Lapho injini iqala, uma i-coolont ibilokhu ijikeleza, kuzoholela ekukhuphukeni kancane kancane ekushiseni kwenjini, futhi amandla enjini azoba buthakathaka futhi ukusetshenziswa kukaphethiloli kuzoba ngaphezulu. Futhi uhla oluncane lokujikeleza okupholile kungathuthukisa izinga lokushisa le-Injini.
Uma i-thermostat ilimele, izinga lokushisa lamanzi enjini lingaphezulu kakhulu. Ngoba okupholile kungahlala ekusakazweni okuncane hhayi ukuqeda ukushisa nge-radiator, izinga lokushisa lamanzi lizovuka.
Ngamafuphi, indima ye-thermostat ukulawula indlela yokujikeleza yokujikeleza kwe-coolant, ngaleyo ndlela yenza ngcono ukusebenza kahle kwenjini nokugwema izinga lokushisa lamanzi ngokweqile. Uma ubhekene nezinkinga zemoto, cabanga ngokubheka ukuthi i-thermostat isebenza kahle.
