Isingeniso sensimbi
I-thermostat ilungisa ngokuzenzakalelayo inani lamanzi angena kurediyetha ngokuvumelana nezinga lokushisa lamanzi okupholisa, futhi ishintsha ububanzi bokujikeleza kwamanzi, ukuze ilungise amandla okukhipha ukushisa esistimu yokupholisa futhi iqinisekise ukuthi injini isebenza ngaphakathi kwebanga lokushisa elifanele. I-thermostat kufanele igcinwe isesimweni esihle sobuchwepheshe, ngaphandle kwalokho izophazamisa kakhulu ukusebenza okuvamile kwenjini. Uma i-valve eyinhloko ye-thermostat ivulwa sekwephuze kakhulu, injini izoshisa kakhulu; Uma i-valve eyinhloko ivulwa ngaphambi kwesikhathi kakhulu, isikhathi sokushisisa injini sizokwelulwa futhi izinga lokushisa lenjini lizoba phansi kakhulu.
Ngamafuphi, umsebenzi we-thermostat ukuvimbela injini ekupholiseni ngokweqile. Isibonelo, ngemva kokuba injini isebenza ngokujwayelekile, uma ingekho i-thermostat lapho ushayela ebusika, izinga lokushisa lenjini lingase libe phansi kakhulu. Ngalesi sikhathi, injini idinga ukumisa okwesikhashana ukuhamba kwamanzi ukuze kuqinisekiswe ukuthi izinga lokushisa lenjini aliphansi kakhulu.
Sisebenza kanjani lesi sigaba
I-thermostat eyinhloko esetshenziswa i-wax thermostat. Uma izinga lokushisa lokupholisa liphansi kunevelu eshiwo, upharafini ocolisisiwe kumzimba wezenzwa we-thermostat uqinile. I-valve ye-thermostat ivala ishaneli phakathi kwenjini ne-radiator ngaphansi kwesenzo se-spring, bese into epholile ibuyela enjinini ngepompo yamanzi ukuze ijikeleze kancane enjinini. Lapho izinga lokushisa elipholile lifinyelela inani elishiwo, upharafini uqala ukuncibilika futhi kancane kancane uba uketshezi, umthamo uyanda futhi ucindezela ishubhu lenjoloba ukuze linciphe. Uma ipayipi lenjoloba lishwabana, lisebenza ukuphokosela phezulu ku-push rod, futhi induku yokusunduza inomphumela obheke phansi obheke phansi kuvalvu ukuze uvule ivalvu. Ngalesi sikhathi, isipholile sigeleza sibuyele enjinini nge-radiator nevalvu ye-thermostat bese sidlula empompini yamanzi ukuze sijikeleze kakhulu. Iningi lama-thermostats lihlelwe kupayipi lokuphuma kwekhanda le-cylinder, elinezinzuzo zesakhiwo esilula futhi kulula ukuqeda ama-bubbles ohlelweni lokupholisa; Okubi ukuthi i-thermostat ivamise ukuvulwa futhi ivalwe ngesikhathi sokusebenza, okuholela ekuzuleni.
