Ko te kaupapa mahi o ngā pā hiko o ngā motuka
Ka whakahaere aunoa te pā hau hiko o te motuka i te pāmahana o te miihini mā te whakamahi i tētahi tikanga whakahaere pāmahana atamai, kia pai ai te mahi i roto i te awhe mahi tino pai.
Whakamārama mō te Mātāpono Mahi
Te Pūoko Pāmahana me te Whakahaere Tīmata/Mutu
Ko ngā wāhanga matua o te pā hiko ko te kaiwhakahaere pāmahana (te pūoko pāmahana wai rānei) me te ECU (Electronic Control Unit) o te mīhini. Ina piki te pāmahana o te whakamatao o te mīhini ki te rohe o runga kua whakaritea (te nuinga o te wā 92°C – 105°C), ka tahuri te kaiwhakahaere pāmahana ki te pūtake hiko, ā, ka tīmata te pā mō te whakamatao kaha. Kia heke te pāmahana ki te awhe haumaru (pēnei i te 88°C – 93°C), ka motuhia e te kaiwhakahaere pāmahana te pūtake hiko, ā, ka mutu aunoa te pā hei karo i te whakamatao nui rawa ka pā ki te pai o te mahi a te mīhini.
Tikanga Whakahaere Tere Maha-Taumata
He maha ngā kōwhiringa tere-rua, he maha rānei ngā tere o te nuinga o ngā pā hiko:
Ina eke te pāmahana o te wai ki te 90°C, ka tere te mahi a te hau pā;
Ina ka piki te pāmahana ki runga ake i te 95°C, ka huri ki te mahi tere-teitei hei whakarei ake i te kaha whakamatao.
Ko te tikanga ka tutukihia tēnei whakahaere mā te pana wera e kite ana i te pāmahana o te wai, ka tukuna he tohu ki te wae whakahaere J293, ka whakamahia he taraiwa ara iahiko hei huri i te huringa mahi, te tohu PWM rānei hei whakahaere i te tere.
Mana Whakahaere Hononga Pūnaha Āhuarangi
Ahakoa kāore anō kia eke te pāmahana wai ki te paepae teitei, mā te tīmata i te hauhautanga ka tīmata te mahi a te hauhautanga. Nā te mea me tuku te wera o te whakamatao hauhautanga kia mau tonu ai te pānga whakamatao, ka tukuna e te rorohiko hauhautanga (J301) he tohu tīmatanga kaha ki te waeine whakahaere hauhautanga (J293), ka mahi tahi te hauhautanga. Mā tēnei ka whai hua te mahi a te hauhautanga, me te ārai hoki i te wera nui o te mīhini nā te kawenga tāpiri.
Te Whakaroa i te Whakamatao i muri i te Whakawetonga o te Mīhini
Kei ētahi tauira waka he āhuatanga "whakaroa whakamatao": I muri i te whakawetonga o te mīhini, ki te noho tonu te pāmahana o te whakamatao ki runga ake i tētahi uara (pēnei i te 117°C), ka haere tonu te hauhautanga mō ētahi meneti tae noa ki te hekenga o te pāmahana ki tētahi taumata haumaru hei ārai i te "kohikohi wera" me ētahi atu ngoikoretanga.
Te Tiaki Hapa me te Aroturuki Pūnaha
Kei ngā pūnaha pā hiko hou ngā tikanga tiaki whānui, tae atu ki te aroturuki i te iahiko, te ngaohiko, me te tere o te motuka i te wā tūturu. Mēnā ka kitea he raruraru pēnei i te ngaohiko nui rawa, te iahiko nui rawa, te ara iahiko poto, te aukati rānei o te motuka, ka whakamahia e te pūnaha whakahaere he tiaki whakaweto hiko hei ārai i te kino o te pūnaha whakamatao katoa.
Te Whakataurite ki Ētahi Atu Momo Pā
Pā Hau Hiko vs Pā Hau Hinu Hikohiko
Ko te pā hiko e whakahaeretia tika ana e te ECU, he tere te urupare me te tino whai hua, he pai mō ngā pūnaha whakahaere wera atamai hou; ko te pā hinu silicone ia e whakahaerehia ana e te āhuatanga ā-tinana o te whakawhānui wera hinu silicone, he hanganga māmā engari he iti ake te tika o te whakahaere.
Pā Hau Hiko vs Pā Hau Mīhini Tuku Iho
Ko ngā pā hau tuku iho e peia tika ana e te whitiki miihini, ā, ka mahi tonu; he nui ake te whakapaunga hiko; i te wā e tīmata ana, e mutu ana hoki te pā hau hiko ina hiahiatia, ka whakaitihia te ngaronga hiko me te whakapai ake i te penapena wahie.
Ka taea te aromatawai mēnā kei te tika te mahi a te pā hiko o te motuka mā te maha o ngā āhuatanga pēnei i te tirotiro i te āhua mahi, te whakarongo ki te tangi, te kite i ngā huringa pāmahana, me te tirotiro i ngā wāhanga e pā ana.
Tikanga Tirotiro Mārama
Tirohia mēnā kei te hurihuri te pā hau
Tīmatahia te mīhini, ka tatari kia piki ake te pāmahana o te wai ki runga ake i te 80°C (mō te 5–10 meneti), kātahi ka whakatuwhera i te taupoki, ka tirotiro mēnā ka tīmata aunoa te pā hau o te radiator. I te nuinga o te wā, ina tae te pāmahana o te wai ki te 90–98°C, me tīmata te pā hau i te tere iti; ki te piki tonu te pāmahana (pērā i runga ake i te 102°C), ka huri ki te aratau tere-teitei.
Tirohia te Mahi Hononga Hauhautanga
Whakakāhia te aratau whakamatao o te hauhautanga, ahakoa kāore i te teitei te pāmahana o te wai, me tīmata anō te hauhautanga ki te āwhina i te whakamatao o te pūwhakamātao. Ki te kore te hauhautanga e aro mai i muri i te whakakānga i te hauhautanga, tera pea he hapa kei roto i te ara iahiko whakahaere, i te whakawhiti rānei.
Te Whakawa Āwhina Whakarongo me te Pā
Whakarongo ki te tangi o te mahi
He haruru "whirring" ōrite te mahi a te pā. Mena he haruru "clanging" rerekē, he haruru koi rānei, tera pea nā te rerekētanga o te mata, te pakaru o te peera, te pakaru rānei o te motuka.
Whakarongohia te Rere o te Hau I raro i ngā āhuatanga haumaru, ina whakatatahia tō ringa ki muri o te pā hau (engari kaua e pā ki ngā mata), me mārama te rongo i te kaha o te rere o te hau. Mēnā kāore he hau, he ngoikore rānei te hau, tera pea he tohu tēnei kāore i te rawaka te mana o te motuka, he tohu rānei tēnei kāore i te mau ngā mata o te pā hau.
Te aroturuki i te pāmahana me te taputapu
Mātakitaki ki te ine pāmahana wai: Ki te noho teitei tonu te pāmahana wai (kei te tata te tohu ki te wāhi whero) ā, kāore te hau e tīmata, he tohu tēnei kāore te hau e mahi ana e ai ki te hiahia.
Ki te haere tonu te hau pā mō ētahi meneti i muri i te whakawetonga o te mīhini, he mahi whakaroa noa iho tēnei mō te whakamatao; engari ki te kore e mutu te hurihuri mō te wā roa, tera pea he hapa kei roto i te pana whakahaere pāmahana, i te waeine whakahaere rānei.
Te tirotiro i ngā wāhanga matua
Tirohia ngā fiusi me ngā relays
Kimihia te pouaka fiusi i roto i te wāhanga miihini, whakaūtia mēnā kua pupuhi te fiusi e pā ana ki te pā hau, me te mēnā kei te mahi tika te reiti. Ka taea e koe te whakamātautau i te mahi a te reiti mā te whakakapi.
Whakamātauria te motuka me te waea
Momotuhia te mono o te pā hau, ka hono tika ki tētahi pūtake hiko 12V. Me taea e te pā hau te huri noa, ā, kaua e rangona he haruru rerekē. Ki te kore, kua pakaru te motuka.
Whakamahia he mita maha hei ine i te ātete o te motuka. Mena he rerekē te ātete (he tiketike rawa, he mutunga kore rānei), he tohu tēnei kei te he te takai o roto.
Whakatau i ngā raruraru o ngā pūoko me ngā pana whakahaere pāmahana
Ki te kore e taea e te pūoko pāmahana wai, e te pana wera rānei te whiwhi i te tohu tīmatanga, ka kore te hau e whiwhi i te tohu tīmatanga. Ka taea e koe te pānui i te rerenga raraunga pāmahana wai mā te whakamahi i tētahi taputapu tātaritanga, te whakamātautau rānei i te pāmahana kawe hiko o te pana whakahaere pāmahana i roto i te wai wera (ko te tikanga he 93–98°C te kawe hiko).
