Te Mahi a ngā Pūnaha Whakamatao Mīhini
Ko ngā haerenga rori, ngā taraiwa pukumahi o te tāone, me ngā haerenga roa i runga i te huarahi tere, e whakawhirinaki katoa ana ki tētahi toa kāore i te rongonuihia—ko te pūnaha whakamatao miihini. Mā tēnei wāhanga nui o tō waka ka whakarite kia oma te miihini i te pāmahana tino pai, kia kore ai e pāngia e te wera nui. Engari me pēhea te mahi a tēnei pūnaha uaua? Ko te whāinga o tēnei tuhinga he ruku hohonu ki ngā kaupapa matua, ngā wāhanga, me ngā tikanga whakahaere o ngā pūnaha whakamatao miihini, kia mārama ai ki tā rātou mahi me ā rātou mahi.
Te Hiahia o ngā Pūnaha Whakamatao Mīhini
Ka puta te wera nui i roto i ngā miihini tahu ā-roto i te wā e mahi ana nā te tahunga o te wahie me te hau. Ahakoa ka tukuna ētahi o tēnei wera mā te pūnaha whakaputanga hau, he nui tonu te wāhanga e toe ana i roto i te miihini. Ki te kore he tikanga hei whakakore i tēnei wera nui, ka tere te eke o ngā wāhanga miihini—tae atu ki ngā piston, ngā rango, me ngā takirere—ki ngā pāmahana ka taea te piko, te rewa, te pakaru rānei o te miihini. Ko te kaupapa matua o te pūnaha whakamatao ko te whakahaere i tēnei wera, kia pai ai te mahi a te miihini me te roa o te ora.
Ngā Wāhanga Matua o te Pūnaha Whakamatao Mīhini
Ko te mārama ki te mahi a te pūnaha whakamatao miihini ka tīmata mā te mōhio ki ōna wāhanga matua:
Radiator
Ko te pūwhakamatao te wāhanga tino kitea o te pūnaha whakamatao. Koia te whakawhiti wera matua, e tuku ana i te wai whakamatao (wai) kua mimiti i te wera o te miihini kia tukuna ki te āhuarangi. He mea hanga mai i te konumohe, i te parahi rānei, ko te pūwhakamatao he ngongo me ngā tara e whakanui ana i te horahanga o te mata mō te marara o te wera.
Te papu papua
Ko te papu wai te wāhanga matua e whakahaere ana i te rere o te wai whakamatao i roto i te miihini, te radiator, me ētahi atu ara whakamatao. E peia ana e te whitiki e hono ana ki te porowhita o te miihini, ka whakarite te papu wai kia rere tonu te wai whakamatao, kia mau tonu te tohatoha pāmahana ōrite puta noa i te miihini.
Tuhinga o mua
Ko te thermostat te kaiwhakahaere pāmahana i roto i te pūnaha whakamatao. Ka noho kati tonu ina makariri te mīhini hei whakaroa i te wā whakamahana, ā, ka tuwhera ina tae te mīhini ki tōna pāmahana mahi tino pai, ka taea ai te rere o te wai whakamatao ki te radiator. Mā tēnei ka mau tonu te pāmahana ōrite o te mīhini, ka whakapai ake i te pai me te mahi.
Whakaoho
Ko te wai whakamatao, te wai ārai huka rānei, te wai e rere ana i roto i te miihini me te pūnaha whakamatao. He ranunga wai me te ethylene glycol, te propylene glycol rānei, he nui te kohua o te wai whakamatao, he iti hoki te kohua huka. Ka ārai i te miihini mai i te huka i ngā pāmahana makariri me te kohua i ngā pāmahana tiketike, ka whakarato i te tiakitanga mō te tau katoa.
Whakahauhia nga Fans
Mā te hono tika ki te mīhini, mā te hiko rānei e whakahaere, ka tukuna he hau atu ki te radiator, ina koa ka tū te waka, ka puhoi rānei te neke. Mā te kukume i te hau mā roto i ngā tara radiator, ka whakarei ake i te marara o te wera, ka ārai i te wera nui i te wā e tere ana te mahi.
Te Pūnaha Whakamatao e Mahi Ana
Ko te mārama ki te mahi tahi a ēnei wāhanga ko te whai i te haerenga o te wai whakamatao i roto i te miihini me te pūnaha whakamatao:
Rere Matahau
1. Wāhi Tīmatanga: Ka tīmata te haerenga i te pūwhakamahana, te wāhi i tukuna ai te wera o te wai whakamatao ki te pāmahana iti iho.
2. Papu Wai: Ka panaia te wai whakamatao e te papu wai ki roto i te poraka miihini me te pane rango mā roto i te raupapa o ngā ngongo me ngā ara.
3. Te mimiti wera: I te rere o te wai whakamatao i roto i te poraka miihini, ka mimiti i te wera mai i te tukanga tahunga. Kātahi ka neke te wai whakamatao wera ki te thermostat.
4. Te Whakahaere i te Werawera: Mena kei raro iho te wai whakamatao i te paepae o te werawera, ka hurihia anō ki roto i te miihini hei pupuri i te wera. Kia neke ake te pāmahana o te wai whakamatao i te paepae, ka tuwhera te werawera, ka taea ai te rere o te wai whakamatao wera ki te radiator.
5. Te Mararatanga o te Wera: I roto i te pūwhakamahana, ka rere te wai whakamatao wera mā roto i ngā ngongo me ngā tara, ka tukuna te wera ki te hau e karapoti ana. Ka taea e ngā pā hau te āwhina i tēnei tukanga mā te whakanui ake i te rere o te hau ina hiahiatia.
6. Te Haere Tonu o te Huringa: Ka hoki te wai kua whakamatao ki te whakamahana, kua rite ki te mahi anō i te huringa.
Nga Momo Punaha Matao
Ahakoa he rite tonu ngā mātāpono matua o ngā pūnaha whakamatao, he rerekē ngā momo hei whakatutuki i ngā hoahoa me ngā tono miihini rerekē:
Ngā Pūnaha Whakamatao-Wai
Ko te momo tino noa i roto i ngā waka hou, arā, ko ngā pūnaha whakamatao-wai, e whakamahi ana i te whakamatao hei whakawhiti i te wera mai i te miihini ki te radiator. Ka taea te whakamahi hei pūnaha kati, hei pūnaha tuwhera rānei:
– Ngā Pūnaha Katia: Ka puritia e ēnei te whakamatao i roto i te taiao hiri, ka whakaiti i te ngaronga nā te mimiti me te whakaiti i te poke.
– Ngā Pūnaha Tuwhera: He puna wai tēnei e āhei ai te whakawhānui me te whakawhāiti i te wai whakamatao, engari he ngāwari ake te turuturu me te poke.
Nga Pūnaha Whakamaeke-rangi
Kāore i te tino kitea i roto i ngā waka hou engari e kitea ana i roto i ētahi miihini tawhito, miihini motuhake rānei (pērā i ngā motopaika, i ngā waka rererangi iti rānei), ka whakawhirinaki katoa ngā pūnaha whakamatao-hau ki te rere o te hau i te taha o te miihini hei whakamarara i te wera. Ka āwhina ngā tara me ngā hipoki ki te whakahaere i te rere o te hau ki ngā wāhi matua, engari he iti ake te whai hua o ēnei pūnaha ki te pupuri i te pāmahana miihini ōrite ki te whakataurite ki ngā pūnaha whakamatao-wai.
Te tiaki me nga take noa
He mea nui te tiaki tika i te pūnaha whakamatao mō te hauora o te mīhini. Me uru atu ki ngā tirotiro auau:
– Te Taumata me te Āhua o te Pūwero Whakamatao: Me whakarite kei te taumata tika te pūwero, ā, kāore he poke.
– Ngā Ngongo me ngā Whitiki: Tirohia mēnā he tohu o te pakaru, o te turuturu rānei.
– Pāmahana: Te tirotiro mō ngā mea e ārai ana, e pakaru ana rānei, ka ārai i te rere o te hau.
– Thermostat: Me whakarite kia tika te mahi hei ārai i te wera nui, te kore rānei e wera rawa.
Ko ngā raruraru noa ka puta ko ngā turuturu o te wai whakamatao, te thermostat e kore e mahi tika ana, te papu wai e kore e mahi, te aukati rānei o te radiator. He mea nui te whakatika i ēnei kia kore ai e kino rawa te miihini.
Opaniraa
He wāhanga uaua, he wāhanga nui hoki te pūnaha whakamatao miihini, e whakataurite ana i te pai o te mahi me te roa o te ora o te miihini mā te pupuri i ngā pāmahana mahi tino pai. Mai i te rere o te whakamatao i roto i te poraka miihini ki te tohatoha wera i roto i te radiator, he mahi nui tā ia wāhanga ki te pupuri i te mahi a te waka. Mā te tiaki auau me te mārama ki te mahi a te pūnaha, ka taea e ngā taraiwa te whakarite kia noho tonu ā rātou miihini i roto i te āhua pai rawa atu, kia rite ai mō tētahi haerenga kei mua.
