Ko ngā pūoko wera tētahi o ngā momo pūoko pāmahana e whakamahia whānuitia ana puta noa i te ao. He rongonui ēnei i roto i ngā momo mara maha nā te mea he ohanga, he pakari, he maha hoki ngā whakamahinga. Ko ngā tono mō ngā pūoko wera he uku, he hau, he hinu, he konganuku, he karāhe me ngā kirihou tae atu ki te kai me te inu.
Ka taea e koe te whakamahi i ēnei ki ngā wāhi katoa hei aroturuki tika, hei tuhi rānei i ngā raraunga pāmahana. E mōhiotia ana ngā thermocouples mō te whakaputa ine pāmahana me te urupare tere me te ātete pai ki te ru, te wiri me ngā pāmahana tiketike.
He pūoko te thermocouple e whakamahia ana hei ine i te pāmahana i roto i ngā mahi pūtaiao, hangahanga, me te hangarau. Ka hangaia mā te hono i ngā waea whakarewa rerekē e rua hei hanga hononga. Ka hangaia e te hononga he ngaohiko matapae i runga i tētahi awhe pāmahana kua hoatu. Ko te tikanga, ka whakamahia e ngā thermocouple te pānga Seebeck, te pānga thermoelectric rānei, hei huri i te ngaohiko hei ine pāmahana.
He maha ngā whakamahinga o ngā thermocouples i roto i te umanga kai me te inu pērā i te whakamātao, te whakamātao, te whakapūkara, te hanga pia me te whakapōtae. Kāore koe e manukanuka i te whakamahi i te ine pāmahana thermocouple nā ​​te mea ka whakaratohia he pānui pāmahana parai me te tunu tika kia tino maoa ai tō kai.
He maha ngā wā ka whakamahia ngā thermocouples i roto i ngā taputapu wharekai pērā i ngā oumu tunu kai, ngā tōstare, ngā parai hohonu, ngā whakamahana, me ngā oumu. Hei tāpiri, ka kitea e koe ngā thermocouples i roto i te ahua o ngā pūoko pāmahana i roto i ngā taputapu kīhini e whakamahia ana i roto i ngā wheketere tukatuka kai nui.
Ka whakamahia hoki ngā thermocouples i roto i ngā whare hanga pia nā te mea me tika ngā pāmahana mō te hanga pia kia tika ai te whakapūkara me te ārai i te poke o ngā moroiti.
He uaua pea te ine tika i te pāmahana o ngā konganuku rewa pērā i te maitai, te konutea me te konumohe nā te tino teitei o ngā pāmahana. Ko ngā pūoko pāmahana e whakamahia whānuitia ana i roto i ngā konganuku rewa ko ngā takirua wera konukawata momo B, S me R me ngā takirua wera konganuku turanga momo K me N. Ko te whiriwhiri i te momo tino pai ka whakawhirinaki ki te awhe pāmahana o te tono motuhake e pā ana ki te konganuku.
Ko ngā thermocouple whakarewa turanga e whakamahi ana i te waea ine US Nama 8, Nama 14 rānei (AWG) me te ngongo whakangungu whakarewa me te ārai uku. Ko ngā thermocouple konukawata, i tetahi atu ringa, e whakamahi ana i te diameter #20 ki te #30 AWG.
Me whakahaere tika te pāmahana i te hanga o ngā hua kirihou. He maha ngā wā e hiahiatia ana ngā thermocouples hei whakahaere i te pāmahana i roto i ngā momo mahi tukatuka kirihou. Ka whakamahia ēnei hei ine i te pāmahana rewa, te pāmahana mata rānei i roto i ngā pokepoke werohanga me ngā pokepoke werohanga.
I mua i te whakamahinga o ngā thermocouples i roto i te tukatuka kirihou, me mōhio koe e rua ngā momo thermocouples i roto i te umanga kirihou. Kei roto i te wāhanga tuatahi ngā inenga. I konei, ka taea te whakamahi i ngā thermocouples hei whakatau i te mahi whakawhiti wera o ngā kirihou i runga i tō rātou wāhanga whakawhiti. Kia mahara me kite te thermocouple i te rerekētanga o te kaha e whakamahia ana, nā tōna tere me te ahunga te nuinga.
Ka taea hoki e koe te whakamahi i ngā thermocouples i roto i te whanaketanga hua i roto i te umanga kirihou. Nō reira, ko te momo tuarua o te whakamahinga o ngā thermocouples i roto i te umanga kirihou ko te hoahoa hua me te hangarau. I roto i te whanaketanga hua, me whakamahi koe i ngā thermocouples hei tatau i ngā huringa pāmahana o ngā rauemi, inā koa i roto i te roanga o te ora o te hua.
Ka taea e ngā kaihangarau te whiriwhiri i ngā takirua wera e tika ana mō ngā rauemi e whakamahia ana e rātou i roto i te hanga o ā rātou hua. Waihoki, ka taea e rātou te whakamahi i ngā takirua wera hei whakamātautau i te mahi a te hoahoa. Mā tēnei ka taea e rātou te hanga huringa i mua i te tīmatanga o te tukanga whakaputa.
Ko ngā āhuatanga o te oumu te mea nui hei whakatau i te takirua wera e tika ana mō te oumu taiwhanga pāmahana teitei. Nō reira, hei whiriwhiri i te takirua wera pai rawa atu, me whai whakaaro ki ētahi āhuatanga, pēnei i:
I te nuinga o te wā, me nui te pēhanga me te pāmahana e hiahiatia ana mō ngā extruders. He miro ngā hononga thermocouples mō ngā extruders hei āwhina i te whakanoho i ō rātou pito probe ki roto i te kirihou rewa, i raro i te pēhanga teitei i te nuinga o te wā.
Ka taea e koe te hanga i ēnei takirua wera hei huānga takitahi, takirua rānei me ngā whare miro ahurei. Ko ngā takirua wera bayonet (BT) me ngā takirua wera kōpeketanga (CF) e whakamahia whānuitia ana i roto i ngā wāhanga extruder pēhanga iti.
He maha ngā whakamahinga o ngā momo thermocouples i roto i ngā ahumahi rerekē. Nō reira, ki te mahi koe i roto i te hangarau, te maitai, te kai me te inu, te tukatuka kirihou rānei, ka kitea e koe he whānuitia te whakamahinga o ngā thermocouples mō te ine me te whakahaere i te pāmahana.
