I-Thermostat luhlobo lwesixhobo sokulawula ubushushu obuzenzekelayo, esihlala siqulathe icandelo lemvakalelo yobushushu, ngokwandisa okanye ukucutheka ukuvula nokucima ukuhamba kolwelo olupholisayo, oko kukuthi, ngokuzenzekelayo ukulungelelanisa amanzi kwiradiyetha ngokweqondo lobushushu lokupholisa. ulwelo, ukutshintsha uluhlu lokujikeleza kolwelo olupholisayo, ukulungelelanisa inkqubo yokupholisa amandla okutshatyalaliswa kobushushu.
Eyona thermostat ye-injini yi-wax-type thermostat, elawulwa yiparafini ngaphakathi ngomgaqo wokwandiswa kobushushu kunye nokufinyela okubandayo ukulawula ukujikeleza kwesipholisi. Xa iqondo lobushushu lokupholisa lingaphantsi kwexabiso elichaziweyo, iparafini esulungekisiweyo kumzimba ovavanyayo ubushushu be-thermostat yomelele, ivalve ye-thermostat phantsi kwentshukumo yasentwasahlobo ukuvala umjelo phakathi kwe-injini kunye neradiyetha, isisipholisi ngempompo yamanzi buyela enjini, umjikelo omncinci we-injini. Xa ubushushu besipholisi bufikelela kwixabiso elichaziweyo, iparafini iqalisa ukunyibilika ize ngokuthe ngcembe ibe lulwelo, kwaye umthamo uyanda kwaye ucinezele ityhubhu yerabha ukuyenza inciphe. Ngelo xesha, ityhubhu yerabha iyancipha kwaye iqhube phezulu kwintonga yokutyhala. Intonga yokutyhala ine-tyholo ezantsi ezantsi kwivalve ukwenza ivalve ivuleke. Ngeli xesha, isisipholisi sihamba kwiradiyetha kunye nevalve ye-thermostat, size emva koko sibuyele e-injini ngempompo yamanzi ukuze sijikelezwe kakhulu. Ininzi ye-thermostat ihlelwe kumbhobho wokuphuma kwamanzi wentloko ye-cylinder, enenzuzo yesakhiwo esilula kwaye kulula ukukhupha iibhubhu kwinkqubo yokupholisa; Ukungalungi kukuba i-thermostat ihlala ivula kwaye ivale xa isebenza, ivelise i-oscillation phenomenon.
Xa ubushushu bokusebenza kwe-injini busezantsi (ngaphantsi kwe-70°C), i-thermostat ivala ngokuzenzekelayo indlela eya kwi-radiator, kwaye ivula indlela eya kwimpompo yamanzi. Amanzi okupholisa aphuma kwibhatyi yamanzi angena kwimpompo yamanzi ngokuthe ngqo kwi-hose, kwaye ithunyelwa kwibhatyi yamanzi ngempompo yamanzi ukuze ijikeleze. Ngenxa yokuba amanzi okupholisa angachithi kwiradiyetha, ubushushu bokusebenza be-injini bunokwandiswa ngokukhawuleza. Xa ukushisa kwe-injini kuphezulu (ngaphezu kwama-80 ° C), i-thermostat ivala ngokuzenzekelayo indlela ekhokelela kwipompo yamanzi, kwaye ivula indlela ekhokelela kwi-radiator. Amanzi okupholisa aphuma kwibhatyi yamanzi apholiswa yiradiyetha aze athunyelwe kwibhatyi yamanzi ngempompo yamanzi, ephucula amandla okupholisa kwaye inqanda injini ekutshiseni. Le ndlela yomjikelo ibizwa ngokuba ngumjikelo omkhulu. Xa ubushushu bokusebenza kwe-injini buphakathi kwama-70 °C nama-80°C, kukho imijikelo emikhulu nemincinane ngaxeshanye, oko kukuthi, inxalenye yamanzi okupholisa kumjikelo omkhulu, kunye nenye inxalenye yamanzi okupholisa kumjikelo omncinci.
Umsebenzi we-thermostat yemoto kukuvala imoto ngaphambi kokuba ubushushu bufike kubushushu obuqhelekileyo. Ngeli xesha, ulwelo olupholileyo lwe-injini lubuyiselwa kwi-injini ngepompo yamanzi, kwaye ukujikeleza okuncinci kwi-injini kuqhutyelwa ukwenza injini ifudumale ngokukhawuleza. Xa iqondo lobushushu lidlula eliqhelekileyo lingavulwa, ukuze ulwelo olupholisayo lutyhutyhe lonke itanki yeradiyetha loop ukuze kujikelezwe olukhulu, ukuze kucinywe ubushushu ngokukhawuleza.
