Me pēhea te whiriwhiri i te pūoko pāmahana tika mō ngā mahi ahumahi

Kupu Whakataki

Ko te pāmahana te taurangi e inehia ana i roto i te whakahaere tukanga ahumahi, tuarua ki te pēhanga. Ahakoa tōna whānui, he hapa nui tonu te whiriwhiri i te momo pūoko hē, ka taea te whakapau i ngā mano tāra mai i ngā tahua whakahaere mā te kore e whakamaheretia, te ngaronga o te hua, me te whakatikatika anō i ngā wā katoa. I roto i te ao ahumahi hou, ehara te tika i te whakaritenga hangarau noa iho; he mea nui hoki i te taha pūtea.

E whakaata ana te mākete pūoko pāmahana o te ao i tēnei hiranga nui, kua 93.5 piriona te uara i te tau 2025, ā, e matapaetia ana ka eke ki te 126.8 piriona i te tau 2030, ka tipu i te tere tipu ā-tau (CAGR) o te 6.28%. I roto i tēnei mākete e tipu haere ana, e matapaetia ana ka rēhitahia e ngā pūoko pāmahana mamati te tere tipu teitei rawa atu i te nekehanga o ngā ahumahi ki te Ahumahi 4.0 me ngā pūnaha hanga atamai. Heoi, ahakoa te maha o ngā kōwhiringa, kei te mau tonu te raruraru matua: he maha ngā wā ka whakapoauau ngā miihini me ngā tohunga hoko i ngā RTD, ngā thermocouples, ngā thermistors, me ngā pūoko infrared, ka hua ake he kōwhiringa kore e tino pai ana ka whakararu i te pono o te pūnaha.

I MEOKON, e mārama ana mātou he pai te pai o tētahi pūoko ina rite ki tōna taunga mō te tono. Hei kaihanga pūoko pono, ka tukuna e mātou he kohinga raupapa pāmahana whānui kua hangaia hei whakatutuki i ngā tono pakari o ngā taiao ahumahi kanorau. Kua hangaia tēnei aratohu kaihoko hei tapahi i ngā kupu hangarau me te whakarato i tētahi anga mahi, whai mana hoki mō te whiriwhiri i te pūoko pāmahana tika mō tō tono ahumahi.

1. Ngā Momo Matua e Whā o ngā Pūoko Pāmahana Ahumahi

Ko te mārama ki ngā mātāpono whakahaere taketake o ngā momo pūoko pāmahana ahumahi matua e whā te taahiraa tuatahi ki te whiriwhiri tika. He painga me he herenga motuhake tō ia hangarau e whakatau ana i tōna pai mō ngā āhuatanga tukanga motuhake.

1.1 RTD (Kaitirotiro Pāmahana Ātete)

Ko te kaupapa o ngā RTD he whakarerekētanga o te ātete hiko o te konganuku i runga i te pāmahana. Ko te paerewa ahumahi tino noa ko te Pt100, e ine ana i te 100Ω i te 0°C, e piri pono ana ki te paerewa IEC 60751.

Ko te whānuitanga pāmahana o ngā RTD e ahu mai ana i te -200°C ki te 850°C. Ko tō rātou painga matua ko te tino tika, mai i te ±0.1°C ki te ±0.5°C (Akomanga A, B, 1/3 DIN rānei), me te kaha ki te whakahoki anō, te pumau mō te wā roa, me te iti o te nekehanga i roto i te wā. Heoi, he rerekē ngā painga o ēnei: ​​He nui ake te utu o ngā RTD, he iti ake te whānuitanga pāmahana o runga ki te whakataurite ki ngā thermocouples, he pakarukaru ā-mīhini, ā, he puhoi ake te wā urupare. Nō reira, he pai rawa atu mō ngā tono e hiahia ana kia tino tika, pērā i te hanga rongoā, te tukatuka kai me te inu, te whakatikatika taiwhanga, me te whakahaere tukanga tino tika.

1.2 Te honohono wera

Ka whakawhirinaki ngā takirua wera ki te pānga Seebeck, ina honoa ngā konganuku rerekē e rua ki tētahi pito ka whakaputa i te ngaohiko e rite ana ki te rerekētanga pāmahana i waenga i te hononga ine me te hononga tohutoro (makariri). Ko ngā momo ahumahi noa ko te Momo K (NiCr-Ni, -200~1260°C), Momo J (Fe-CuNi, 0~760°C), Momo T (Cu-CuNi, -250~350°C), Momo N (NiCrSi-NiSi, -270~1300°C), me ngā momo konganuku rangatira S/R/B (PtRh-Pt, tae atu ki te 1768°C).

Ahakoa he iti iho te tika o ēnei i ngā RTD (te tikanga he ±0.75% o te pānui, he ±1.0°C rānei), he tino pai ngā thermocouples i roto i ngā taiao tino kino. He whānui ake te awhe pāmahana e tukuna ana e rātou, he hanganga pakari, he tere rawa ngā wā urupare (he maha ngā mirihekona), me te iti o te utu. Ko ngā ngoikoretanga ko te iti ake o te tika, te ngawari ki te neke haere i roto i te wā, te hiahia mō te utu mō ngā hononga makariri, me te putanga kore-raina. Koinei te paerewa ahumahi mō ngā oumu ahumahi, ngā whakamātautau rererangi, ngā whakamātautau motuka, me ngā tukanga whakarewa pāmahana-tiketike.

1.3 Te Whakamahana (NTC/PTC)

He taputapu uku haurua-haurua ngā whakamahana, ā, ka tino rerekē te ātete i te pāmahana. Ka heke te ātete o ngā whakamahana Tauwehenga Pāmahana Kino (NTC) i te pikinga o te pāmahana, ka piki ake ngā momo Tauwehenga Pāmahana Pai (PTC).

Ko te tikanga, e mahi ana i waenga i te -50°C me te 300°C, ko ngā whakamahana te mea tino aro ki te tairongo o ngā pūoko pāmahana katoa, he maha ngā wā e whakaatu ana i te huringa 3-5% ia °C. Ko te tikanga o tēnei he tere rawa ngā wā urupare, he iti te utu, ā, he iti te rahi. Heoi, ko te putanga tino kore-raina me whai i te whakarārangitanga whārite Steinhart-Hart mō ngā pānui tika. He iti hoki te whānuitanga, ā, he ngāwari ki te whakamahana-ake. He pai ngā whakamahana mō ngā pūnaha whakahaere wera pākahiko, ngā tono HVAC, ngā hikohiko kaihoko, me ngā taputapu hauora e hiahiatia ana he tairongo teitei i roto i te whānuitanga whaiti.

1.4 Ngā Pūoko Pāmahana Pūwhero (Kore-Pa)

Ka kitea e ngā pūoko infrared te irahiko wera e tukuna ana e ngā mea, ka hurihia hei tohu hiko me te kore e pā atu ki te tinana. Mā tēnei huarahi kore-whakaeke ka taea e rātou te ine i ngā mea e neke ana, e tino wera ana, e kore rānei e taea te uru atu, me te tere tere o te urupare.

Ko ngā ngoikoretanga matua o ngā pūoko pūwero whero ko tōna ngāwari ki te pokanoa ki te taiao (puehu, mamaoa, paoa), te whakawhirinaki ki te kaha o te ūnga, me te herenga ki te ine i te pāmahana o te mata anake. He nui ake hoki te utu. He mea nui ēnei pūoko i roto i ngā taiao morearea, mō te aroturuki i ngā rauemi neke pēnei i te maitai, te karāhe rānei i runga i ngā kaikawe, me ngā mahi tukatuka kai ina āraia te pa atu e te akuaku.
