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 da zazzabi 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 kula; da Ma'aunin zafi da sanyio na lantarki suna gano yanayin zafi ta hanyar ma'aunin zafin jiki mara kyau (NTC), sannan kuma suna sarrafa tsarin samar da wutar lantarki na kwampreso ta hanyar relay ko thyristor, ta haka ne ake gane yanayin zafin jiki.
(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 yana kunshe da firikwensin thermal, bimetal, fil, lamba, reed reed, da dai sauransu, kamar yadda aka nuna a ƙasa. zuwa sama ba tare da taɓa fil ɗin ba, kuma ana rufe lambar sadarwa ƙarƙashin aikin sandar lamba. Tare da ci gaba da dumama, bayan zafin zafin da thermostat ya gano ya kai darajar da aka saita, bimetal ya lalace kuma an danna ƙasa, kuma ana lankwasa lambar tuntuɓar ta ƙasa ta fil ɗin, yana haifar da sakin lambar, kuma na'urar ta daina aiki saboda. babu 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 a zafi ba, yi amfani da maɓallin “R × 1″ na multimeter don auna ƙimar juriya tsakanin tashoshi na bimetal thermostat. Idan ƙimar juriya ba ta da iyaka, yana nufin cewa kewaye yana buɗewa; kuma yanayin zafin da yake ganowa ya kai ƙimar ƙima, ƙimar juriya ba zata iya zama marar iyaka kuma har yanzu tana 0, wanda ke nufin lambobin sadarwa a ciki suna mannewa.
