Ka'idar aiki na na'urar kariya ta thermal

1.Nau'in na'urorin kariya na thermal
Nau'in tsiri Bimetallic mai kariyar zafi: Mafi na kowa, yana amfani da halayen zafin jiki na bimetallic tube.
Nau'in na'ura mai ɗaukar nauyi na yanzu: Yana haifar da kariya dangane da girman halin yanzu da aka jawo.
Nau'in haɗe (zazzabi + halin yanzu): A lokaci guda saka idanu zafin jiki da na yanzu.
2. Ƙa'idar aiki na bimetallic tsiri overheat kariya
Abubuwan da ake buƙata:
Bimetallic tsiri: Ana yin shi ta hanyar latsa ƙarfe biyu tare da ƙididdiga daban-daban na faɗaɗa thermal da lanƙwasa lokacin zafi.
Tuntuɓi: Haɗa jeri a cikin da'irar compressor don sarrafa kashewa.
Tsarin aiki:
1. Halin al'ada:
Lokacin da zafin jiki / halin yanzu ya kasance na al'ada, bimetallic tsiri ya kasance madaidaiciya, lambobin sadarwa suna rufe, da'irar suna gudana, kuma compressor yana aiki.
2.Lokacin da yayi zafi sosai ko yayi yawa:
Zazzabi mai yawa: Saboda rashin ƙarancin zafi ko aiki na tsawon lokaci, zafin jiki na compressor yana tashi, yana haifar da tsiri na bimetallic don lankwasa saboda zafi kuma lambobin sadarwa sun karye, don haka yanke da'ira.
Wuce kima na halin yanzu: Lokacin da aka yi lodi, kayan dumama da ke cikin kariyar ya yi zafi, a kaikaice yana haifar da tsiri bimetallic don tanƙwara da karya lambobi.
3. Sake saitin bayan sanyaya:
Bayan yanayin zafi ya faɗi, tsiri na bimetallic zai dawo zuwa matsayinsa na asali, lambobin sadarwa suna sake rufewa, kuma compressor ya sake farawa.
3. Ƙa'idar aiki na masu kare kaya na yanzu
Ƙaddamar da halin yanzu ta hanyar tasirin lantarki ko juriya dumama:
Lokacin da halin yanzu ya wuce ƙimar da aka saita (kamar lokacin da aka kulle compressor), juriya a cikin ma'ajin yana yin zafi sosai, yana haifar da tsiri bimetallic don lalata da karya kewaye.
Bayan halin yanzu ya dawo al'ada, mai tsaro zai sake saitawa.
4. Yanayin aikace-aikace
Kwampreso na kwandishan: Yana hana zafi fiye da kima sakamakon rashin isassun firji, ƙarancin zafi ko rashin kwanciyar hankali.
Compressor na firiji: Ka guji ƙonawa sakamakon yawan farawa ko nauyi mai yawa.

5. Sauran hanyoyin kariya
PTC thermistor: Wasu na'urori na zamani suna amfani da ma'aunin zafin jiki mai inganci. Mafi girman zafin jiki, mafi girma juriya, don haka iyakance halin yanzu.
Tsarin kariyar lantarki: Yana lura da zafin jiki / halin yanzu a ainihin lokacin ta hanyar na'urori masu auna firikwensin kuma yana yanke wutar lantarki ta hukumar sarrafawa (mafi daidai).
