I-thermostat yemoto.
Isenzo somkhiqizo
I-thermostat kufanele igcinwe isesimweni esihle sokusebenza, ngaphandle kwalokho izophazamisa kakhulu ukusebenza okuvamile kwenjini. Uma i-thermostat ivuleka (nansi ivalve eyinhloko ye-knuckle thermostat) sekwephuzile kakhulu noma ingakwazi nokuvuleka, izobangela injini ukuba ishise kakhulu; Vula kusenesikhathi kakhulu, isikhathi sokushisisa injini siyanwetshwa, ukuze izinga lokushisa lenjini libe liphansi kakhulu.
Isimiso sokusebenza
I-Thermostat (I-Thermostat) iwuhlobo lwedivayisi yokulawula izinga lokushisa okuzenzakalelayo, ngokuvamile iqukethe izingxenye ezizwa izinga lokushisa, ngokunwetshwa noma ukufinyela ukuze uvule, vala ukugeleza kwesipholile, okusho ukuthi, ngokwezinga lokushisa loketshezi olupholisayo lungisa ngokuzenzakalelayo amanzi kurediyetha, uguqule uhla lokujikeleza kokupholisa, ukuze ulungise umthamo wokupholisa wesistimu yokupholisa.
I-thermostat esetshenziswa injini ngokuyinhloko i-thermostat ye-wax, elawulwa yi-wax kapharafini ngaphakathi kokujikeleza kokupholisa ngokusebenzisa isimiso sokunwetshwa kokushisa nokufinyela okubandayo. Lapho izinga lokushisa lokupholisa liphansi kunevelu eshiwo, upharafini ocolisisiwe osemzimbeni ozwa izinga lokushisa we-thermostat uqinile, i-valve ye-thermostat ivala umzila phakathi kwenjini ne-radiator ngaphansi kokusebenza kwentwasahlobo, futhi isipholile sibuyela enjinini ngepompo yamanzi ukuze sijikeleze kancane enjinini. Lapho izinga lokushisa elipholile lifinyelela inani elishiwo, upharafini uqala ukuncibilika futhi kancane kancane ube uketshezi, ivolumu iyakhula futhi ucindezela ishubhu lenjoloba ukuze linciphe, kuyilapho ishubhu lenjoloba lincipha, induku yokusunduza inyakaza ekusunduzeni phezulu, futhi induku yokusunduza inomphumela obheke phansi obheke phansi ukuze uvule ivalvu. Ngalesi sikhathi, isipholile sigeleza kurediyetha kanye nevalvu ye-thermostat, bese sigeleza sibuyele enjinini ngepompo ukuze sijikeleze kakhulu. Iningi le-thermostat lihlelwe kupayipi lokuphuma kwekhanda le-cylinder, elinenzuzo yesakhiwo esilula nokukhishwa kalula kwama-bubbles ohlelweni lokupholisa; Okubi ukuthi i-thermostat ivamise ukuvuleka futhi ivale lapho isebenza, okuholela ekuzuleni.
Lapho izinga lokushisa lenjini liphansi (ngaphansi kuka-70°C), i-thermostat ivala ngokuzenzakalelayo indlela eya kurediyetha, futhi ivula indlela eya epompo, amanzi apholisayo ageleza esuka ejazini aqonde ngqo epayipini aye empompini, kanye nephampu ingene ejazini ukuze ijikeleze, ngenxa yokuthi amanzi okupholisa awahlakazi i-radiator, ingenza izinga lokushisa lenjini elisebenzayo likhuphuke ngokushesha, lo mjikelezo womjikelezo. Uma izinga lokushisa lenjini liphezulu (80°C noma ngaphezulu), i-thermostat ivala ngokuzenzakalelayo indlela eholela epompo, bese ivula indlela eholela kurediyetha, amanzi apholisayo agelezayo esuka ejazini apholiswa i-radiator abese ethunyelwa ejazini ngepompo, okwenza ngcono ukupholisa ukuze kuvinjwe injini ekushiseni ngokweqile, lo mzila womjikelezo ubizwa ngokuthi umjikelezo omkhulu. Lapho izinga lokushisa lokusebenza kwenjini liphakathi kuka-70 no-80 ° C, imijikelezo emikhulu nemincane iba khona ngesikhathi esifanayo, okungukuthi, ingxenye yamanzi okupholisa ukuze ajikeleze kakhulu, kuyilapho enye ingxenye yamanzi okupholisa isakaza kancane.
Iqhaza le-thermostat yemoto ukuvala ngaphambi kokuba izinga lokushisa lemoto lingafiki ezingeni elijwayelekile lokushisa, futhi isipholile senjini sibuyiselwa enjinini ngephampu yamanzi ukuze senze ukujikeleza okuncane enjinini, ukuze injini ikwazi ukushisa ngokushesha. Uma izinga lokushisa elivamile leqiwe, lingavulwa ukuze kuvunyelwe isipholile ukuthi sijikeleze kumjikelezo werediyetha wethangi lonke ukuze kukhishwe ukushisa ngokushesha.
Ukuhlolwa komkhiqizo
Impilo ephephile ye-wax thermostat ivamise ukuba ngu-50,00km, ngakho-ke kuyadingeka ukuyishintsha njalo ngokuya nempilo yayo ephephile. Hlola indlela ye-thermostat kumshini wokushisisa we-thermostat oshintshwayo hlola izinga lokushisa elivulekayo le-valve eyinhloko ye-thermostat, izinga lokushisa elivulekile eligcwele kanye nokuphakamisa, okukodwa kwakho okungahlangabezani nenani elimisiwe elimisiwe, i-thermostat kufanele ishintshwe. Isibonelo, i-thermostat yenjini ye-Santana JV, izinga lokushisa lokuvula le-valve eyinhloko lingu-87 ° C plus noma susa u-2 ° C, izinga lokushisa eligcwele lokuvula lingu-102 ° C plus noma khipha 3 ° C, futhi ukuphakamisa okugcwele kokuvula ngu-> 7mm.
Iphutha elenzeka
Ngaphansi kwezimo ezijwayelekile, lapho injini iqala, izinga lokushisa elisebenzayo liphansi kakhulu, ukuze izinga lokushisa likhuphuke ngokushesha, bese ngokusebenzisa isilawuli se-thermostat (i-valve enkulu ye-thermostat ivaliwe), ukuze ukupholisa ngepompo eliwuketshezi kungene epayipini lamanzi, isipholile singagelezi kurediyetha, lokhu umjikelezo omncane, lapho izinga lokushisa lesipholisa lifinyelela kumadigri angu-87 (I-Bora ye-thermostat, i-valve evulekile, i-valve evulekile, i-valve evulekile isipholile siqala ukugeleza kurediyetha, futhi uhlelo lokupholisa lungena emjikelezweni omkhulu Ngokujwayelekile, cishe imizuzu emihlanu ngemva kokuba imoto iqalile, izinga lokushisa elipholile lingafinyelela izinga lokushisa elivamile lama-degree angu-85 ~ 105, uma izinga lokushisa elivamile lingafinyelelwanga isikhathi eside, noma izinga lokushisa likhuphuke ngaphezu kwamadigri angu-110, kufanele kusolwe ukuthi i-thermostat iyifa.
