Thermostat ndi mtundu wa kutentha kwamphamvu komwe kumathandizira, nthawi zambiri kumakhala ndi kutentha komwe kumapangitsa kuti madzi ozizira azikhala molingana ndi kutentha kwa madzi ozizira, kusintha madzi ozizira ozizira.
Injini ya majerestat yayikulu ndi sera, yomwe imayang'aniridwa ndi paraffin mkati mwa matenthedwe a kuwonjezeka kwa mafuta ndikuzizira kuwongolera kufalikira. Pamene kutentha kozizira ndikotsika kuposa mtengo womwewo, parafini woyengeka mu kutentha kwa thermastic ndi yolimba, valato ya thermostat pansi pa kasupe kuti mutseke mu injini, injini yozizirayo. Pamene kutentha kwa chigonjetso kumafika pamtengo wotsimikizika, parafini imayamba kusungunuka ndipo pang'onopang'ono amakhala madzi, ndipo voliyumu imawonjezeka ndikusindikiza chubu cha mphira kuti chizichepetsa. Nthawi yomweyo, chubu cha mphira chimachepa ndipo chimakhala ndi mphamvu yokweza ndodo. Ndodo yokankhira imakhala ndi mphamvu yotsika pa valavu kuti valavu itseguke. Pakadali pano, ozizira amayenda kudzera mu radiator ndi valavu ya thermastat, kenako amabwerera ku injini kudzera pampu yamadzi yosefukira kwambiri. Ambiri mwa thermostat amakonzedwa mu chitoliro chamadzi chamutu, chomwe chimakhala ndi mawonekedwe osavuta komanso osavuta kutulutsa thovu m'dongosolo lozizira; Choyipacho ndikuti thermate imatha kutseguka ndikutseka pamene likugwira ntchito, kupanga zoscillationblenn.
Makina ogwiritsira ntchito injiniyo akatsika (pansi pa 70 ° C), thermostat imatseka njira yomwe ikutsogolera ku radiator, ndikutsegula njira yomwe ikupita pampu yamadzi. Madzi ozizira omwe akutuluka jekete yamadzi amalowa pampu yamadzi kudzera mu payipi ya payipiyo, ndipo amatumizidwa kumadzi am'madzi ndi pampu yamadzi yofalitsidwa. Chifukwa madzi ozizira sataya ndi radiator, kutentha kwa injiniyo kumatha kuwonjezeka mwachangu. Kutentha kwa injinizi kumakhala kokwera (pamwamba pa 80 ° C), thermostat imatseka njira yopita ku pompo, ndikutsegula njira yomwe ikutsogolera ku radiator. Madzi ozizira omwe amatuluka jekete yamadzi amakhazikika ndi radiator kenako ndikutumiza ku jekete yamadzi ndi pampu yamadzi, yomwe imapangitsa injini yozizira ndipo imalepheretsa injini kuti isatenthe. Njira yozungulira iyi imatchedwa kuzungulira kwakukulu. Pamene kutentha kwa injini kumakhala pakati pa 70 ° C ndi 80 ° C, mizere yayikulu ndi yaying'ono imakhala nthawi yomweyo, ndiye kuti, gawo lina la madzi ozizira kuti azizungulira pang'ono.
Ntchito ya bongo yagalimoto ndiyotseka galimoto kutentha sikunafikire kutentha wamba. Pakadali pano, madzi ozizira a injiniyo amabwezeretsedwanso ku injini ndi pampu yamadzi, ndipo kufalitsidwa pang'ono mu injini kumachitika kuti injini zizitentha mwachangu. Matenthedwe akapitilira zabwinobwino akhoza kutsegulidwa, kotero kuti madzi ozizira kudzera mu tank radiator loop kuti afanongeke kwambiri, kuti athe kutentha.
