Tsarin tsari da gwajin Thermostat

Don sarrafa yanayin sanyi na kayan aikin firiji kamar firiji da na'urorin sanyaya iska da zafin jiki na na'urorin dumama wutar lantarki, ana shigar da ma'aunin zafi da sanyio a kan na'urorin firiji da na'urorin dumama wutar lantarki.
1. Rarrabe na thermostats
(1) Rarraba ta hanyar sarrafawa
Thermostats za a iya raba iri biyu: inji irin da lantarki irin bisa ga iko method.The inji thermostats gane zafin jiki ta hanyar da zafin jiki ji capsule, sa'an nan sarrafa da kwampreso ikon samar da tsarin ta hanyar inji tsarin, game da shi gane zafin jiki iko; da lantarki thermostats gane da zazzabi ta hanyar wani korau zafin jiki coefficient (NTC) thermistor, sa'an nan sarrafa ikon samar da wutar lantarki tsarin, ko damfara da relay relay da wutar lantarki relay tsarin.
(2) Rarraba ta hanyar abun da ke ciki
Za a iya raba ma'aunin zafi da sanyio zuwa bimetal thermostats, masu sanyaya thermostats, Magnetic thermostats, thermocouple thermostats da lantarki ma'aunin zafi da sanyio bisa ga abun da suke ciki.
(3) Rarrabe ta hanyar aiki
Za a iya raba thermostats zuwa ma'aunin zafin jiki na firiji, na'urar kwandishan, ma'aunin zafi da sanyio shinkafa, injin wutar lantarki, ma'aunin zafi da sanyio, ma'aunin zafi da sanyio, microwave tanda thermostats, barbecue tanda thermostats, da sauransu bisa ga fuction.
(4) Rarraba bisa ga yadda lambobin sadarwa ke aiki
Za'a iya raba ma'aunin zafi da sanyio zuwa nau'in tuntuɓar buɗaɗɗen al'ada da nau'in lamba da aka rufe bisa ga yanayin aiki na lambobi.
2. Ganewa da gwaji na bimetal thermostats
Hakanan ana kiran ma'aunin zafin jiki na Bimetal thermostat kuma aikinsa shine sarrafa zafin dumama na'urar dumama wutar lantarki.

(1) Haɗawa da ƙa'idar bimetal thermostat
Bimetal thermostat kunshi thermal firikwensin, bimetal, fil, lamba, lamba Reed, da dai sauransu, kamar yadda aka nuna a kasa.Bayan da wutar lantarki dumama na'urar, shi ya fara zafi, da kuma lokacin da zafin jiki gano da thermostat ya yi ƙasa, da bimetallic takardar lankwasa sama ba tare da taba fil, da lamba a rufe a karkashin mataki na lamba reed. Tare da ci gaba da dumama, bayan zafin da aka gano ta thermostat ya kai darajar da aka saita, bimetal ya lalace kuma an danna ƙasa, kuma ana lankwasa tuntuɓar tuntuɓar ƙasa ta hanyar fil, yana haifar da sakin lambar, kuma na'urar ta daina aiki saboda rashin wutar lantarki. , Na'urar dumama lantarki ta shiga yanayin adana zafi. Tare da tsawo na lokacin riƙewa, zafin jiki ya fara raguwa. Bayan thermostat ya gano shi, an sake saita bimetal, ana jawo lambar sadarwa a ƙarƙashin aikin reed, kuma ana kunna da'irar wutar lantarki na hita don fara dumama. Ta hanyar maimaita tsarin da ke sama, ana samun sarrafa zafin jiki ta atomatik.

(2) Gwajin thermostat na bimetal
Kamar yadda aka nuna a ƙasa, Lokacin da ba mai zafi ba, yi amfani da maɓallin "R × 1" na multimeter don auna ƙimar juriya tsakanin ma'aunin zafi na bimetal. Idan ƙimar juriya ba ta da iyaka, yana nufin cewa kewaye yana buɗewa; kuma yawan zafin jiki da yake ganowa ya kai ƙimar ƙima, ƙimar juriya ba zai iya zama marar iyaka kuma har yanzu yana 0, wanda ke nufin lambobin da ke ciki suna mannewa.
