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, okungukuthi, ngokuya ngezinga lokushisa loketshezi olupholisa ngokuzenzakalelayo lungisa amanzi angene endaweni epholile. irediyetha, shintsha ububanzi bokujikeleza kwesipholile, 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. Uma 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 injini ngepompo yamanzi ukuze ijikeleze kancane enjinini. Lapho izinga lokushisa elipholile lifinyelela inani elishiwo, upharafini uqala ukuncibilika futhi kancane kancane ube uketshezi, umthamo uyakhula futhi ucindezela ishubhu lenjoloba ukuze linciphe, kuyilapho ishubhu lenjoloba lincipha, induku yokusunduza inyakaza ibheke phezulu, futhi induku yokusunduza. ine-reverse ebheke phansi eqondise i-valve ukuze uvule i-valve. 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 empompini, amanzi apholisayo ageleza esuka ejazini adlule ngqo epayipini angene empompini, kanye nephampu. ebhantshini ukuze ajikeleze, ngenxa yokuthi amanzi okupholisa awachithi nge-radiator, angenza izinga lokushisa lenjini likhuphuke ngokushesha, lo mzila womjikelezo ubizwa ngokuthi umjikelezo omncane. 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 yi-radiator bese ethunyelwa. ejazini ngepompo, ukuthuthukisa amandla okupholisa ukuvimbela 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.
Indima ye-thermostat yemoto ukuvala ngaphambi kokuba izinga lokushisa lemoto lingafinyeleli ezingeni lokushisa elijwayelekile, futhi isipholile senjini sibuyiselwa enjinini ngepompo yamanzi ukuze senze ukujikeleza okuncane enjinini, ukuze injini ingashisa 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 liyi-87 ° C plus noma lisusa u-2 ° C, izinga lokushisa eligcwele lokuvula lingu-102 ° C plus noma susa 3 ° C, futhi ukuvuleka okugcwele > 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 eyinhloko ye-thermostat ivaliwe), ukuze isipholile ngepompo eliwuketshezi singene epayipini lamanzi, i-coolant ayigelezi ku-radiator, lokhu umjikelezo omncane, lapho izinga lokushisa le-coolant lifinyelela kuma-degrees angu-87 (i-Bora thermostat evulekile izinga lokushisa lama-degrees angu-87, Ngemva kwalokho, i-valve ye-thermostat iyavuleka, i-coolant iqala ukugeleza ku-radiator; 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 elipholile lingafinyelelwanga. izinga lokushisa likhuphuke ngaphezu kwama-degree angu-110, kufanele kusolwe ukuthi i-thermostat inephutha yini.
