Thermostat ndi mtundu wa chipangizo chowongolera kutentha, chomwe nthawi zambiri chimakhala ndi gawo lozindikira kutentha, pokulitsa kapena kuchepera kuti mutsegule ndikuchotsa kutuluka kwamadzi ozizira, ndiko kuti, kusintha madziwo kukhala mu radiator malinga ndi kutentha kwa kuzizira. madzi, kusintha kufalitsidwa osiyanasiyana madzi kuzirala, kusintha kuzirala dongosolo kutentha dissipation mphamvu.
Thermostat ya injini yayikulu ndi sera yamtundu wa sera, yomwe imayendetsedwa ndi parafini mkati mwa mfundo ya kufutukuka kwa matenthedwe ndi kutsika kwa kuzizira kuwongolera kuzungulira kwa koziziritsa. Kutentha kozizira kumakhala kotsika kuposa mtengo womwe watchulidwa, parafini woyengedwa mu thupi lozindikira kutentha kwa thermostat amakhala olimba, valavu ya thermostat pansi pakuchita kwa masika kutseka njira pakati pa injini ndi radiator, choziziritsa kupitilira pa mpope wamadzi. kubwerera ku injini, injini yaing'ono mkombero. Pamene kutentha kwa choziziritsa kukufika pamtengo wotchulidwa, parafini imayamba kusungunuka ndipo pang'onopang'ono imakhala madzi, ndipo voliyumu imawonjezeka ndikukanikizira chubu la rabara kuti lichepetse. Panthawi imodzimodziyo, chubu cha rabara chimachepa ndipo chimapangitsa kukankhira mmwamba pa ndodo yokankhira. Kukankhira ndodo kumakhala ndi kutsika pansi pa valve kuti valavu itseguke. Panthawiyi, choziziritsa kukhosi chimayenda kudzera pa radiator ndi valavu ya thermostat, kenako chimabwereranso ku injini kudzera pa mpope wamadzi kuti uziyenda kwambiri. Ambiri a thermostat amakonzedwa mu chitoliro chamadzi chotulutsira madzi amutu wa silinda, womwe uli ndi mwayi wosavuta komanso wosavuta kutulutsa thovu munjira yozizira; Choyipa ndichakuti thermostat nthawi zambiri imatsegula ndikutseka ikamagwira ntchito, ndikupanga chodabwitsa cha oscillation.
Kutentha kwa injini kukatsika (pansi pa 70 ° C), chotenthetsera chimangotseka njira yopita ku radiator, ndikutsegula njira yopita ku mpope wamadzi. Madzi ozizira omwe amatuluka mu jekete lamadzi amalowa mu mpope wamadzi mwachindunji kupyolera mu payipi, ndipo amatumizidwa ku jekete lamadzi ndi mpope wa madzi kuti azizungulira. Chifukwa madzi ozizira samatayika ndi radiator, kutentha kwa injini kungathe kuwonjezeka mofulumira. Pamene kutentha kwa injini kuli pamwamba (pamwamba pa 80 ° C), chotenthetsera chimangotseka njira yopita ku mpope wa madzi, ndikutsegula njira yopita ku radiator. Madzi ozizira omwe amatuluka mu jekete lamadzi amatsitsidwa ndi radiator ndiyeno amatumizidwa ku jekete lamadzi ndi mpope wamadzi, zomwe zimapangitsa kuti kuzizira kukhale kozizira komanso kulepheretsa injini kutenthedwa. Njira yozungulira iyi imatchedwa mkombero waukulu. Pamene kutentha kwa injini kuli pakati pa 70 ° C ndi 80 ° C, mizere yayikulu ndi yaying'ono imakhalapo nthawi imodzi, ndiko kuti, gawo la madzi ozizira kwa mkombero waukulu, ndi gawo lina la madzi ozizira kwa kachitidwe kakang'ono.
Ntchito ya thermostat yagalimoto ndikutseka galimoto isanakwane kutentha kwabwino. Panthawiyi, madzi ozizira a injini amabwereranso ku injini ndi mpope wamadzi, ndipo kuyendayenda kochepa mu injini kumachitika kuti injiniyo itenthe mofulumira. Pamene kutentha kuposa zachibadwa akhoza anatsegula, kuti kuzirala madzi kudzera lonse thanki rediyeta kuzungulira lalikulu kufalitsidwa, kuti mwamsanga kutentha kuzimiririka.
