Filayen aikace-aikace na bimetallic thermometers

Ma'aunin zafi da sanyio na Bimetallic nau'i ne na kayan auna tuntuɓar sadarwa, wanda ya dace da kan - auna zafin wurin a matsakaici da ƙananan yanayin zafi. Ana iya amfani da shi kai tsaye auna zafin gas, ruwa da tururi a cikin kewayon - 80 ~ 500 ℃. Kyakkyawan samfuri ne don maye gurbin ma'aunin zafin jiki na mercury na masana'antu. Ana amfani da shi sosai a fannin mai, masana'antar sinadarai, injina, ginin jirgi, samar da wutar lantarki da sauran sassan binciken masana'antu da kimiyya. Yana da fa'idodin rashin haɗarin mercury, sauƙin karantawa, mai dorewa da sauransu.

The principle of the bimetallic thermometer is to measure the temperature by using the principle that two kinds of metal composite sheets of different materials have different coefficients of thermal expansion and contraction, resulting in distortion and driving the pointer deflection. Ɗayan ƙarshen takardar bimetal an gyara shi, kuma ɗayan ƙarshen yana haɗi zuwa madaidaicin juyawa. Lokacin da zafin jiki ya canza, takardar bimetal tana jujjuya axially, ta haka za ta motsa jujjuyawar juyi don juyawa, kuma jujjuyawar ramin tana motsa mai nuni don karkatar da kwana don nuna ƙimar zafin bugun bugun kira. Tsarin asali ya ƙunshi bugun kira, maɓuɓɓugar kusurwa, madaidaicin juzu'i, nau'in gano zafin jiki, bututun kariya, da na'urorin gyara daban-daban. (rufin tebur, casing, gilashin, zobe na rufewa, panel, mai nuna alama, ɓangarorin bazara na ƙananan kayyade, bazara na kusurwa, kusurwar bazara ta sama, jujjuyawar shaft, nau'in gano zafin jiki, bututun kariya, haɗin gwiwa na bututun kariya, zaren waje da hula). Matsin lamba gabaɗaya yana a ƙayyadadden zafin jiki na aiki, matsatsin tsaye wanda bututun kariya zai iya jurewa ba tare da karye ba. Matsakaicin ƙididdiga ba wai kawai yana da alaƙa da bututun kariya ba, diamita da kauri na bango, amma kuma yana da alaƙa da hanyar shigarwa, zurfin shigarwa, da nau'in da ƙimar matsakaicin matsakaici. Tsawon bututun kariya na ma'aunin zafi da sanyio na bimetallic da aka saka a cikin matsakaicin ma'auni shine ƙaramin zurfin shigar, wanda shine sau 8 diamita na bututun kariya.

Dangane da hanyar haɗin kai farantin nuni na ma'aunin zafi da sanyio na bimetal da bututu mai karewa, ana iya raba ma'aunin ma'aunin zafi da sanyio zuwa nau'ikan nau'ikan guda huɗu: nau'in axial, nau'in radial, nau'in shugabanci na 135 ° da nau'in duniya.

1. Nau'in thermometer bimetallic axial: an haɗa farantin mai nuni a tsaye tare da bututu mai karewa.
2. Nau'in ma'aunin zafi da sanyio na radial na bimetallic: an haɗa farantin mai nuni a layi daya tare da bututu mai karewa.
3. 135° bimetallic ma'aunin zafi da sanyio: an haɗa farantin nuni zuwa bututu mai karewa a 135°.
4. Ma'aunin zafi da sanyio na bimetallic na duniya: kusurwar haɗin kai tsakanin farantin nuni da bututun kariya ana iya daidaita su ba da gangan ba.
