Kodi kupindika kwa thermostat yagalimoto n'chiyani?
Kupindika kwa thermostat yagalimoto ndi chinthu chomwe thermostat imasinthasintha chifukwa cha kutentha ndi kufupika. Ma thermostat nthawi zambiri amapangidwa ndi mapepala opyapyala achitsulo. Akatenthedwa, pepala lachitsulo limapindika chifukwa cha kutentha. Kupindika kumeneku kumatumizidwa ku zolumikizira za thermostat kudzera mu kutentha, motero kupanga kutentha kokhazikika .
Momwe thermostat imagwirira ntchito
Chotenthetsera chimagwiritsa ntchito chinthu chotenthetsera chamagetsi kuti chitenthetse pepala lachitsulo, zomwe zimapangitsa kuti litenthedwe ndikupindika. Kupindika kumeneku kumafalikira kudzera mu kutentha komwe kumakhudza thermostat, zomwe zimapangitsa kuti kutentha kukhale kokhazikika. Chochitika ichi chopindika pansi pa kutentha chimadziwika kuti "mphamvu yeniyeni ya kutentha", yomwe ndi kukula kwachilengedwe ndi kupindika kwa chinthu panthawi yotenthetsera kapena kuzizira .
Mtundu wa thermostat
Pali mitundu itatu ikuluikulu ya ma thermostat a magalimoto: bellows, bimetal sheets ndi thermistor . Mtundu uliwonse wa thermostat uli ndi mfundo zake zogwirira ntchito komanso zochitika zogwiritsira ntchito:
Bellows : Kutentha kumayendetsedwa ndi kusintha kwa bellows pamene kutentha kumasintha.
lamba la bimetallic: pogwiritsa ntchito kuphatikiza kwa mapepala awiri achitsulo okhala ndi ma coefficients osiyanasiyana okulitsa kutentha, dera limayendetsedwa mwa kupindika kutentha kukasintha.
Thermistor: Mtengo wotsutsa umasintha ndi kutentha kuti ulamulire kuyatsa ndi kuzima kwa dera.
Momwe mungagwiritsire ntchito thermostat
Thermostat imagwiritsidwa ntchito kwambiri mu makina oziziritsira mpweya m'galimoto, ntchito yayikulu ndikuzindikira kutentha kwa pamwamba pa evaporator, kuti azitha kuwongolera kutsegula ndi kutseka kwa compressor. Kutentha mkati mwa galimoto kukafika pamtengo wokonzedweratu, thermostat imayambitsa compressor kuti iwonetsetse kuti mpweya ukuyenda bwino kudzera mu evaporator kuti ipewe chisanu; Kutentha kukatsika, thermostat imazimitsa compressor, ndikusunga kutentha mkati mwa galimoto kukhala koyenera .
Ntchito ya thermostat ndikusintha njira yoyendera mpweya ya choziziritsira mpweya. Magalimoto ambiri amagwiritsa ntchito mainjini ozizira ndi madzi, omwe amachotsa kutentha kudzera mu kayendedwe kosalekeza ka choziziritsira mpweya mu injini. Choziziritsira mpweya mu injini chili ndi njira ziwiri zoyendera mpweya, imodzi ndi yozungulira kwambiri ndipo ina ndi yozungulira pang'ono.
Injini ikangoyamba kumene, kayendedwe ka coolant kamakhala kochepa, ndipo coolant sidzatulutsa kutentha kudzera mu radiator, zomwe zimapangitsa kuti injini itenthe mofulumira. Injini ikafika kutentha kwabwinobwino, coolant idzazunguliridwa ndikufalikira kudzera mu radiator. Thermostat imatha kusintha njira yozungulira malinga ndi kutentha kwa coolant, motero imawonjezera magwiridwe antchito a injini.
Injini ikayamba, ngati choziziritsira chakhala chikuzungulira, izi zimapangitsa kuti kutentha kwa injini kukwere pang'onopang'ono, ndipo mphamvu ya injini idzakhala yofooka ndipo mafuta adzagwiritsidwa ntchito kwambiri. Ndipo choziziritsira chochepa chozungulira chingathandize kuti kutentha kwa injini kukwere.
Ngati thermostat yawonongeka, kutentha kwa madzi a injini kungakhale kokwera kwambiri. Chifukwa chakuti choziziritsiracho chingakhalebe mu kayendedwe ka madzi kochepa ndipo sichingatulutse kutentha kudzera mu radiator, kutentha kwa madzi kudzakwera.
Mwachidule, ntchito ya thermostat ndikuwongolera njira yoyendera kwa coolant, motero kukonza magwiridwe antchito a injini ndikupewa kutentha kwambiri kwa madzi. Ngati mukukumana ndi mavuto a galimoto, ganizirani zowona ngati thermostat ikugwira ntchito bwino.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
