Kodi thermostat ya galimoto ndi chiyani?
Ma thermostat agalimoto amagwira ntchito yofunika kwambiri mu dongosolo loziziritsira la galimoto. Mwa kuwongolera mwanzeru njira yoyendera ya choziziritsira, zimaonetsetsa kuti injini nthawi zonse imagwira ntchito bwino pa kutentha. Thermostat ndi valavu yomwe imalamulira kuyenda kwa choziziritsira. Chigawo chake chachikulu ndi chinthu chomwe chimakhudzidwa ndi kutentha, chofanana ndi valavu yowongolera yokha m'galimoto.
Mitundu ndi ntchito
Pali mitundu yambiri ya ma thermostat, kuphatikizapo ma bellows, ma bimetal sheet, ndi ma thermostat a thermistor. Thermostat ya bellows imamva kusintha kwa kutentha kudzera mu sensa ya kutentha ndi kapangidwe ka bellows, thermostat ya bimetal sheet imalamulira kutseguka ndi kutsekedwa kwa kukhudzana kudzera mu kusintha kwa bimetal sheet, ndipo thermistor thermostat imalamulira kuyatsidwa kwa compressor circuit kudzera mu kusintha kwa resistance value .
Malo oyika ndi ntchito yake
Thermostat nthawi zambiri imayikidwa pa ngalande yamadzi ya makina oziziritsira ndipo imayang'anira kukula ndi kayendedwe ka choziziritsira. Kayendedwe ka choziziritsira kamagawidwa m'magawo ang'onoang'ono ndi ma cycle akuluakulu, ndipo thermostat imayang'anira kutentha kwa injini powongolera njira yoyendera ya choziziritsira. Thermostat ikazima, choziziritsira chimangoyenda pang'onopang'ono, ndipo thermostat ikayatsidwa, choziziritsira chimatha kuyendayenda m'ma cycle akuluakulu .
Mawonekedwe a zolakwika ndi njira zodziwira
Kulephera kwa thermostat nthawi zambiri kumawonekera m'magawo atatu: kuzimitsa kwathunthu, kuzimitsa kwathunthu, ndi kutsekeka. Kutseka kwathunthu kumapangitsa kuti injini itenthe kwambiri, kutsegulidwa kwathunthu kumapangitsa kuti kutentha kwa injini kukhale kotsika kwambiri, ndipo kutsekeka kumapangitsa kuti kutentha kusakhazikika. Kuti muwone ngati thermostat ikugwira ntchito bwino, mutha kuweruza pokhudza kusintha kwa kutentha kwa mapaipi amadzi apamwamba ndi apansi .
Ntchito yaikulu ya thermostat yagalimoto ndikusintha njira yoyendera ya coolant kuti zitsimikizire kuti injini ikhoza kutulutsa kutentha bwino pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito. Makamaka, powongolera njira yoyendera ya coolant, thermostat imalola injini kutentha mwachangu ikayamba kuzizira ndikusunga kutentha koyenera kugwira ntchito panthawi yogwira ntchito bwino.
Mfundo yogwirira ntchito
Mkati mwa thermostat muli chinthu chomwe chimakhudzidwa ndi kutentha, nthawi zambiri chimakhala parafini. Injini ikayamba, kutentha kwa coolant kumakhala kochepa, parafini imakhalabe yolimba, ndipo thermostat imatseka njira yoyendetsera coolant kupita ku radiator, zomwe zimathandiza kuti coolant iyende mwachindunji mu injini block kapena cylinder head water jacket kudzera pa pampu, motero imawonjezera kutentha kwa injini mofulumira. Kutentha kwa madzi kukafika kutentha kwina (nthawi zambiri pafupifupi madigiri 85), parafini imayamba kusungunuka, thermostat imatseguka pang'onopang'ono, ndipo coolant imayamba kuzungulira kwambiri kudzera mu radiator kuti ichotse kutentha, potero imayang'anira mphamvu yozizira ndikuwonetsetsa kuti injini ikugwira ntchito nthawi zonse kutentha koyenera .
Zotsatira zolakwika
Ngati thermostat ikugwira ntchito molakwika, monga kusayatsa kapena kuzimitsa bwino, ingayambitse mavuto awa:
Kutenthedwa kwa injini: Ngati thermostat siikuyatsa bwino ndipo choziziritsira sichidutsa mu radiator kuti chichotse kutentha, injini ikhoza kutentha kwambiri, zomwe zimapangitsa kuti ntchito yake isagwire bwino ntchito kapena kuwonongeka.
Vuto loyambitsa kuzizira: ngati thermostat yayatsidwa msanga kwambiri, choziziritsira chimalowa mu gawo lalikulu msanga kwambiri, zingayambitse nthawi yayitali yotenthetsera injini, kutentha kochepa, zomwe zimakhudza magwiridwe antchito komanso kusunga mafuta moyenera.
Malangizo okonza
Pofuna kuonetsetsa kuti injini ikugwira ntchito bwino, tikukulimbikitsani kuti nthawi zonse muziyang'ana ndikusunga momwe thermostat ikugwira ntchito. Ngati thermostat ikupezeka kuti ikugwira ntchito molakwika, iyenera kusinthidwa nthawi ndi nthawi kuti ipewe zotsatirapo zoyipa pa magwiridwe antchito a injini ndi moyo wake.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
