Chidziwitso cha zida
Thermostat imangosintha kuchuluka kwa madzi omwe amalowa mu radiator molingana ndi kutentha kwa madzi ozizira, ndikusintha momwe madzi amayendera, kuti asinthe mphamvu ya kuziziritsa kutentha ndikuwonetsetsa kuti injini imagwira ntchito mkati mwa kutentha koyenera. Thermostat iyenera kusungidwa muukadaulo wabwino, apo ayi idzakhudza kwambiri magwiridwe antchito a injini. Ngati valavu yaikulu ya thermostat imatsegulidwa mochedwa kwambiri, injiniyo idzatentha kwambiri; Ngati valavu yayikulu itsegulidwa molawirira kwambiri, nthawi yotenthetsera injini italikirapo ndipo kutentha kwa injini kumakhala kotsika kwambiri.
Mwachidule, ntchito ya thermostat ndikuletsa injini kuti isatenthedwe. Mwachitsanzo, injini itatha kugwira ntchito bwino, ngati palibe thermostat poyendetsa m'nyengo yozizira, kutentha kwa injini kungakhale kotsika kwambiri. Panthawiyi, injiniyo iyenera kuyimitsa kaye kaye kayendetsedwe ka madzi kuonetsetsa kuti kutentha kwa injini sikutsika kwambiri.
Momwe gawoli limagwirira ntchito
Thermostat yayikulu yomwe imagwiritsidwa ntchito ndi sera yotentha. Kutentha kozizira kumakhala kotsika kuposa mtengo womwe watchulidwa, parafini woyengedwa mu thermostat sensing thupi amakhala wolimba. Valavu ya thermostat imatseka njira pakati pa injini ndi rediyeta pansi pa kasupe, ndipo choziziritsa kukhosi chimabwerera ku injini kudzera pa mpope wamadzi kuti chizungulire pang'ono mu injini. Kutentha kozizirirako kukafika pamtengo womwe watchulidwa, parafini imayamba kusungunuka ndipo pang'onopang'ono imakhala yamadzimadzi, voliyumu imawonjezeka ndikukakamiza chubu la rabara kuti lichepetse. Chitoliro cha rabara chikachepa, chimakankhira m'mwamba pa ndodo yokankhira, ndipo ndodoyo imakhala ndi valavu yobwerera kumbuyo kuti itsegule valavu. Panthawiyi, choziziriracho chimabwereranso ku injini kudzera pa radiator ndi valavu ya thermostat, kenako kudzera pa mpope wamadzi kuti uziyenda kwambiri. Ambiri ma thermostats amakonzedwa mu chitoliro chotulutsira chamutu wa silinda, womwe uli ndi ubwino wa dongosolo losavuta komanso losavuta kuthetsa thovu mu dongosolo lozizira; Choyipa ndichakuti thermostat nthawi zambiri imatsegulidwa ndikutsekedwa panthawi yogwira ntchito, zomwe zimapangitsa kuti pakhale oscillation.
