He aha ka thermostat?
Loaʻa nā inoa like ʻole o nā mea hoʻoponopono wela, e like me nā hoʻololi hoʻomalu wela, nā mea pale wela a me nā mea mālama wela.Wahi a ka loina hana, hiki ke hoʻokaʻawale ʻia i ka thermostat type jump, thermostat type wai, thermostat type pressure and thermostat type electronic.I nā mea hoʻokele ʻenehana hou, ʻo ka thermostat digital ka ʻano maʻamau i hoʻohana ʻia.Wahi a ka hoʻolālā, hiki ke hoʻokaʻawale ʻia ka mea hoʻokele wela i ka mea hoʻoponopono wela hoʻohui a me ka modular temperature controller.
He aha nā mea wela?
ʻO ke kino ana wela he mea ia e hoʻololi i ka hōʻailona wela i hōʻailona uila, a hoʻokomo pinepine ʻia ma ka ʻāpana ʻike o ka mea i hoʻomalu ʻia e nānā i kona waiwai wela.Ma ke kahua o ka ʻoihana hoʻomalu, hoʻohana mau ʻia nā thermometers me nā thermocouple, nā pale pale wela, nā thermistors a me nā ʻike pili ʻole.Ma waena o lākou, ʻo nā mea mua ʻekolu he thermometer contact.
1. Thermocouple
Hoʻokumu ʻia ke kumu o ke ana wela no nā thermocouple ma ka hopena Seebeck (hopena thermoelectric).Ke hoʻopili ʻia nā metala ʻelua o nā mea like ʻole (ka mea maʻamau i nā conductors a i ʻole semiconductor, e like me ka platinum-rhodium, nickel-chromium-nickel-silicon a me nā mea ʻē aʻe i hoʻopaʻa ʻia) e hana i kahi loop pani a hoʻopili i nā wela like ʻole i ko lākou mau ʻaoʻao pili ʻelua, hana ʻia kahi mana electromotive ma waena. na metala elua.Ua kapa ʻia kēlā ʻano loop he "thermocouple," ʻoiai ua kapa ʻia nā metala ʻelua he "thermal electrode," a ʻo ka hopena electromotive i kapa ʻia he "thermoelectric motive force."Hōʻike ʻia nā Thermocouples e ko lākou ākea ākea ākea, pane wela wikiwiki, a me ke kūpaʻa haʻalulu ikaika.
2. Ke pale wela
ʻO ke kūpaʻa wela he mea ia e hoʻololi ai i kahi hōʻailona wela i hōʻailona uila, a ʻo kāna kumu hana i hoʻokumu nui ʻia ma nā ʻano o ka hoʻololi ʻana i ka metala me ka mahana.ʻO ke kikoʻī, hoʻohana nā mea pale wela i kēia waiwai o ka metala e ana i ka mahana.
I loko o ka mana ʻoihana, ʻo nā ʻano mea maʻamau o ka pale ʻana i ka wela ka platinum, ke keleawe a me ka nickel.I waena o lākou, ʻo ka pale platinum ka mea maʻamau.Loaʻa i ka thermal resistance nā hiʻohiʻona o ka linearity wela maikaʻi, ka hana paʻa a me ka precision kiʻekiʻe ma ke kahua o ka mahana maʻamau.No laila, i loko o ke kaiapuni noi o ka mahana wela, ʻaʻohe vibration a me nā koi precision kiʻekiʻe, ʻoi aku ka makemake o ka hoʻohana ʻana i ka pale platinum.
3. ʻO ka wela wela
ʻO ka thermistor kahi mea e hoʻololi ai i kahi hōʻailona wela i hōʻailona uila, a ʻo kāna kumu hana i hoʻokumu nui ʻia i nā hiʻohiʻona o ke kūpaʻa semiconductor e loli ana me ka mahana.ʻO ke kikoʻī, hoʻohana nā thermistors i kēia waiwai o semiconductors e ana i ka mahana.Ke hoʻohālikelike ʻia me ke kūpaʻa wela, hoʻololi nui ke kūpaʻa o ka thermistor me ka hoʻololi ʻana o ka mahana, no laila he haiki kona ana wela (-50 ~ 350 ℃).
Hoʻokaʻawale ʻia nā Thermistors i NTC thermistors a me PTC thermistors.NTC thermistors loaʻa i ka maikaʻiʻole wela coefficient, a me ko lakou kū'ē waiwai ho'ēmi i ka piʻi 'ana o ka mahana.Loaʻa i ka PTC thermistor kahi helu wela maikaʻi, a e piʻi aʻe kona waiwai kū'ē me ka piʻi ʻana o ka mahana.Ma muli o kāna mau hiʻohiʻona kūʻokoʻa kūʻokoʻa, loaʻa ka thermistor i kahi ākea o nā noi i ka ʻike wela, ka mana otometi, nā mea uila a me nā kahua ʻē aʻe.
Hoʻokumu ʻo Zhuo Meng Shanghai Auto Co., Ltd. e kūʻai aku i nā ʻāpana kaʻa MG&MAUXS e hoʻokipa ʻia e kūʻai.
