I-Thermostat iwuhlobo lwedivayisi elawula izinga lokushisa okuzenzakalelayo, ngokuvamile equkethe ingxenye ezwa izinga lokushisa, ngokunwetshwa noma ngokuncipha ukuze uvule futhi uvale ukugeleza koketshezi olupholisayo, okungukuthi, ukulungisa ngokuzenzakalelayo amanzi kurediyetha ngokuvumelana nezinga lokushisa lokupholisa. uketshezi, shintsha ububanzi bokujikeleza koketshezi olupholile, ukuze ulungise umthamo wokukhipha ukushisa wesistimu yokupholisa.
I-thermostat yenjini eyinhloko i-thermostat yohlobo lwe-wax, elawulwa upharafini ngaphakathi ngesimiso sokunwetshwa kokushisa nokufinyela okubandayo ukuze kulawulwe ukujikeleza kokupholisa. Lapho izinga lokushisa lokupholisa liphansi kunevelu eshiwo, upharafini ocolisisiwe osemzimbeni ozwa izinga lokushisa le-thermostat uqinile, i-valve ye-thermostat ngaphansi komnyakazo wentwasahlobo ukuvala umzila phakathi kwenjini ne-radiator, isipholile ngepompo yamanzi ukuze buyela enjinini, umjikelezo omncane wenjini. Lapho izinga lokushisa lesipholile lifinyelela inani elishiwo, upharafini uqala ukuncibilika futhi kancane kancane uba uketshezi, futhi umthamo uyanda futhi ucindezela ishubhu lenjoloba ukuze linciphe. Ngesikhathi esifanayo, ishubhu lenjoloba liyashwabana futhi liqhubele phezulu ku-push rod. I-push rod inokuqondisa phansi kwe-valve ukwenza i-valve ivuleke. Ngalesi sikhathi, isipholile sigeleza kurediyetha kanye nevalvu ye-thermostat, bese sigeleza sibuyele enjinini ngepompo yamanzi ukuze sijikeleze kakhulu. Iningi le-thermostat lihlelwe epayipini lokuphuma kwamanzi lekhanda le-cylinder, elinenzuzo yesakhiwo esilula futhi kulula ukukhipha ama-bubbles ohlelweni lokupholisa; Okubi ukuthi i-thermostat ivamise ukuvuleka futhi ivale lapho isebenza, ikhiqize i-oscillation phenomenon.
Uma izinga lokushisa lenjini liphansi (ngaphansi kuka-70°C), i-thermostat ivala ngokuzenzakalelayo indlela eholela kurediyetha, bese ivula indlela eholela epompo lamanzi. Amanzi okupholisa aphuma ebhantshini lamanzi angena empompini yamanzi ngokuqondile ngepayipi, futhi athunyelwa ejazini lamanzi ngepompo yamanzi ukuze ajikeleze. Ngenxa yokuthi amanzi okupholisa awachithi nge-radiator, izinga lokushisa elisebenzayo lenjini lingakhuphuka ngokushesha. Lapho izinga lokushisa lokusebenza kwenjini liphezulu (ngaphezu kuka-80 ° C), i-thermostat ivala ngokuzenzakalelayo indlela eholela empompini yamanzi, futhi ivule indlela eholela kurediyetha. Amanzi okupholisa aphuma ebhantshini lamanzi apholiswa i-radiator bese ethunyelwa ebhantshini lamanzi ngepompo yamanzi, okuthuthukisa amandla okupholisa futhi avimbele injini ekushiseni ngokweqile. Lo mzila womjikelezo ubizwa ngokuthi umjikelezo omkhulu. Lapho izinga lokushisa lokusebenza kwenjini liphakathi kuka-70 °C no-80°C, imijikelezo emikhulu nemincane iba khona ngesikhathi esisodwa, okungukuthi, ingxenye yamanzi okupholisa umjikelezo omkhulu, kanye nenye ingxenye yamanzi okupholisa umjikelezo omncane.
Umsebenzi we-thermostat yemoto ukuvala imoto ngaphambi kokuba izinga lokushisa lifike ezingeni lokushisa elijwayelekile. Ngalesi sikhathi, uketshezi olupholile lwenjini lubuyiselwa enjinini ngepompo yamanzi, futhi ukujikeleza okuncane enjinini kwenziwa ukuze injini ifudumale ngokushesha. Lapho izinga lokushisa idlula evamile ingavulwa, ukuze uketshezi Ukupholisa ngokusebenzisa lonke ithangi kurediyetha loop for kwegazi elikhulu, ukuze ngokushesha ukushisa ukushabalalisa.
