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 hui pū ʻia) i kahi puka pani a hoʻopili i nā mahana like ʻole i ko lākou mau ʻaoʻao pili ʻelua, hana ʻia kahi mana electromotive ma waena o 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 kahi 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 pono 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 pololei kiʻekiʻe ma ke kahua o ka mahana maʻamau. No laila, i ka hoʻohana ʻana i ka mahana maʻalahi, ʻaʻohe vibration a me nā koi precision kiʻekiʻe, ʻoi aku ka maikaʻi 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 e hoʻokumu nui ʻia ma nā ʻano o ke kūʻē semiconductor e loli ana me ka mahana. Ma keʻano kūikawā, hoʻohana nā thermistors i kēia waiwai o nā 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.
Ua kūpaʻa ʻo Zhuo Meng Shanghai Auto Co., Ltd. e kūʻai aku i nā ʻāpana kaʻa MG&MAUXS e hoʻokipa ʻia e kūʻai.
