Ngā Thermocouples Hipokina Pāmahana Teitei
Whakaahuatanga Hua
Ko ngā takirua wera kua whakakikoruatia (e mōhiotia ana ko ngā takirua wera kua whakamahanahia ki te kohuke) he pūoko pāmahana ahumahi mahi teitei i hangaia mō ngā tono uaua.Ko ngā momo matua ko K, N, E, J, T, me S, ka taea te ine i ngā pāmahana mai i te -200°C ki te 1300°C mō ngā wai, te mamaoa, ngā hau, me ngā mata totoka.
E whakamahia whānuitia ana ngā takirua wera kua whakakikoruatia puta noa i ngā ahumahi pēnei i te hinu, te matū, te whakaputa hiko, te whakarewa, me te rererangi.
He pūoko pāmahana te thermocouple kua hipokina, he mea hanga mā te tukanga whakakīkī ā-mīhini, e whakauru ana i ngā waea thermocouple, te rauemi whakamahana, me te hipoki whakarewa. He ngāwari, he ātete ki te pāmahana teitei, me te manawanui ki te pēhanga teitei. Ki te whakatauritea ki ngā thermocouple tuku iho, he iti ake te diameter o te momo kua hipokina, ā, he pai ake te piko, he pai mō te ine pāmahana i ngā wāhi whaiti, uaua ki te tae atu, me te tuku tere hoki i te urupare.
Te Mātāpono Mahi o ngā Thermocouples Whakakikoruatia
He rite tonu te kaupapa ine pāmahana o tētahi thermocouple hipoki ki tērā o tētahi thermocouple paerewa, e ahu mai ana i te pānga Seebeck. Ina he rerekētanga pāmahana kei waenganui i te hononga ine (pito wera) me te hononga tohutoro (pito makariri/pito hononga), ka puta he kaha hiko wera (EMF) i roto i te ara iahiko i hangaia e ngā kaiārahi rerekē e rua. Mā te ine i tēnei EMF wera, ka taea te whakatau i te pāmahana i te hononga ine.
Ngā Āhuatanga o ngā Thermocouples Kua Whakakikoruatia
• He tere te urupare wera me te iti o te hapa hihiri
• He kaha ā-mīhini teitei, ātete ki te pēhanga, te pānga, me te wiri
• Tāutanga ngāwari nā te mea ka taea te piko
• Ātete ki ngā pāmahana teitei me te waikura
Ngā Whakamahinga o ngā Thermocouples Kua Whakakikoruatia
• Te whakahaere tukanga ahumahi:Te aroturuki me te whakahaere i te pāmahana i roto i ngā paipa, ngā tauhohenga, me ētahi atu taputapu i roto i ngā ahumahi hinu, matū, me te hiko.
• Ngā whakamahinga pāmahana teitei me te whakarewa:Te ine i te pāmahana i roto i ngā taputapu pāmahana-tiketike pērā i ngā oumu me ngā oumu pahū i roto i ngā ahumahi maitai me te sima.
• Ngā taiao motuhake:Te ine pāmahana urupare-tere, i te ine rānei i te pāmahana i roto i ngā whakamātautau miihini rererangi me ngā rangahau pūtaiao.
• Ngā āhuatanga e hiahiatia ana:Ngā taiao mahi uaua e pā ana ki te wiri, te pēhanga teitei, ngā whakaritenga mō te tāutanga piko, te hiahia rānei kia tere te urupare.
Ngā Momo Hononga Ine Thermocouple
Momo whenua:Ka honoa te hononga ine ki te pūtu, ā, ka tere ake te urupare. Heoi, kāore e pai mō ngā mea kawe hiko, ngā mea waikura rānei.
Momo kore whenua:Kua āraihia te hononga ine e te hiko mai i te pūtu. He puhoi ake te urupare engari he kaha te ātete ki te haruru, koinei te momo e whakamahia whānuitia ana, ā, he roa te ora mahi.
Momo kua whakakitea:Kei waho o te uhi te hononga ine, ā, he tino tere te urupare. Heoi, he ngāwari te pakaru o ngā waea, ā, ka whakamahia noa iho ki ngā mea maroke, kāore e waikura.
