I-thermostat yemoto.
Isenzo somkhiqizo
I-thermostat kumele igcinwe isesimweni esihle sokusebenza, ngaphandle kwalokho izothinta kakhulu ukusebenza okuvamile kwenjini. Uma i-thermostat ivuleka (nansi ivalvu eyinhloko ye-thermostat ye-knuckle) sekwephuzile noma ingavuleki, izobangela ukuthi injini ishise ngokweqile; Ivuleke kusenesikhathi, isikhathi sokushisa injini siyandiswa, ukuze izinga lokushisa lenjini libe phansi kakhulu.
Isimiso sokusebenza
I-Thermostat (i-Thermostat) uhlobo lwedivayisi yokulawula izinga lokushisa okuzenzakalelayo, ngokuvamile iqukethe izingxenye zokuzwa izinga lokushisa, ngokunwebeka noma ngokufinyela ukuvula, ukuvala ukugeleza kwe-coolant, okungukuthi, ngokusho kwezinga lokushisa loketshezi olupholile, lungisa ngokuzenzakalelayo amanzi abe yi-radiator, ushintshe ububanzi bokujikeleza kwe-coolant, ukuze ulungise umthamo wokupholisa wesistimu yokupholisa.
I-thermostat esetshenziswa yinjini ngokuyinhloko i-thermostat ye-wax, elawulwa yi-paraffin wax ngaphakathi kokujikeleza kwe-coolant ngokusebenzisa umgomo wokwanda kokushisa kanye nokuncipha kokubanda. Lapho izinga lokushisa lokupholisa liphansi kunenani elibekiwe, i-paraffin ehlanziwe emzimbeni ozwa izinga lokushisa we-thermostat iqinile, i-thermostat valve ivala umzila phakathi kwenjini ne-radiator ngaphansi kokusebenza kwentwasahlobo, bese i-coolant ibuyela enjinini ngephampu yamanzi ukuze kujikeleze kancane enjinini. Lapho izinga lokushisa le-coolant lifika enanini elibekiwe, i-paraffin iqala ukuncibilika futhi kancane kancane ibe uketshezi, ivolumu iyanda futhi icindezele ithubhu yerabha ukuze inciphe, kuyilapho ithubhu yerabha incipha, induku yokucindezela isebenza ekucindezelweni okuphezulu, kanti induku yokucindezela inokucindezela okuphambene phansi evalvini ukuvula ivalvu. Ngalesi sikhathi, i-coolant igeleza nge-radiator kanye ne-thermostat valve, bese igeleza iphindela enjinini ngephampu ukuze kujikeleze kakhulu. Iningi le-thermostat lihlelwe epayipini lokukhipha i-cylinder head, elinenzuzo yesakhiwo esilula kanye nokukhishwa okulula kwama-bubbles ohlelweni lokupholisa; Ububi ukuthi i-thermostat ivame ukuvula nokuvala lapho isebenza, okuholela ekunyakazeni.
Uma izinga lokushisa lokusebenza kwenjini liphansi (ngaphansi kuka-70°C), i-thermostat ivala ngokuzenzakalelayo indlela eya ku-radiator, futhi ivule indlela eya ku-pump, amanzi okupholisa ageleza esuka ejakethini ngqo ngepayipi angene ephampini, kanye ne-pump ingene ejakethini ukuze kujikelezwe, ngoba amanzi okupholisa awanyamalali yi-radiator, angenza izinga lokushisa lokusebenza kwenjini likhuphuke ngokushesha, lo mzila womjikelezo ubizwa ngokuthi umjikelezo omncane. Uma izinga lokushisa lokusebenza kwenjini liphezulu (80°C noma ngaphezulu), i-thermostat ivala ngokuzenzakalelayo indlela eholela ephampini, futhi ivule indlela eholela ku-radiator, amanzi okupholisa ageleza esuka ejakethini apholiswa yi-radiator bese ethunyelwa ejakethini yi-pump, okuthuthukisa ukuqina kokupholisa ukuvimbela injini ekushiseni ngokweqile, lo mzila womjikelezo ubizwa ngokuthi umjikelezo omkhulu. Uma izinga lokushisa lokusebenza kwenjini liphakathi kuka-70 no-80°C, imijikelezo emikhulu nemincane ikhona ngesikhathi esisodwa, okungukuthi, ingxenye yamanzi okupholisa ukuze kujikelezwe kakhulu, kanti enye ingxenye yamanzi okupholisa ukuze kujikelezwe kancane.
Indima ye-thermostat yemoto ukuvala ngaphambi kokuba izinga lokushisa lemoto lingafiki ezingeni lokushisa elijwayelekile, bese i-coolant yenjini ibuyiselwa enjinini ngephampu yamanzi ukuze yenze ukujikeleza okuncane enjinini, ukuze injini ikwazi ukushisa ngokushesha. Uma izinga lokushisa elijwayelekile selidluliwe, lingavulwa ukuze kuvunyelwe i-coolant ukuthi ijikeleze ngesekethe ye-radiator yethangi lonke ukuze kuqedwe ukushisa okusheshayo.
Ukuhlolwa komkhiqizo
Impilo ephephile ye-thermostat ye-wax ngokuvamile ingamakhilomitha angu-50,00, ngakho-ke kuyadingeka ukuyishintsha njalo ngokwempilo yayo ephephile. Hlola indlela ye-thermostat ku-thermostat elungisekayo lokushisa imishini yokushisa hlola izinga lokushisa lokuvula le-valve enkulu ye-thermostat, izinga lokushisa elivulekile eligcwele kanye nokuphakamisa, okunye okungahlangabezani nenani elijwayelekile elibekiwe, i-thermostat kufanele ishintshwe. Isibonelo, i-thermostat yenjini ye-Santana JV, izinga lokushisa lokuvula le-valve enkulu lingu-87 ° C kanye noma lingaphansi kuka-2 ° C, izinga lokushisa lokuvula eligcwele lingu-102 ° C kanye noma lingaphansi kuka-3 ° C, kanti i-lift yokuvula egcwele ingu-> 7mm.
Isenzakalo sephutha
Ngaphansi kwezimo ezijwayelekile, lapho injini iqala, izinga lokushisa lokusebenza liphansi kakhulu, ukuze izinga lokushisa likhuphuke ngokushesha, bese lidlula ngokulawula i-thermostat (i-valve enkulu ye-thermostat ivaliwe), ukuze i-coolant ngepompo yoketshezi ingene epayipini lamanzi, i-coolant ingadluli nge-radiator, lokhu kuwumjikelezo omncane, lapho izinga lokushisa le-coolant lifinyelela kuma-degree angu-87 (izinga lokushisa le-thermostat le-Bora livulekile lama-degree angu-87, Ngemva kwalokho, i-valve ye-thermostat iyavuleka, i-coolant iqala ukugeleza nge-radiator, futhi uhlelo lokupholisa lungena emjikelezweni omkhulu. Ngokuvamile, cishe imizuzu emihlanu ngemva kokuqala kwemoto, izinga lokushisa le-coolant lingafinyelela izinga lokushisa elijwayelekile lama-degree angu-85 ~ 105, uma izinga lokushisa elijwayelekile lokusebenza lingafinyelelwanga isikhathi eside, noma izinga lokushisa likhuphuke ngaphezu kwama-degree angu-110, kufanele kusolwe ukuthi i-thermostat inephutha yini.
Sicela usishayele ucingo uma udinga usizoimikhiqizo ye-ch.
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS futhi wamukelekile ukuzithenga.
