He whakamahana waka: Te "kaitiaki whakahaere pāmahana" me te aratohu whakatau raruraru
Ko te whakamahana waka, e mōhiotia whānuitia ana ko te whakamahana, te wāhanga matua o te pūnaha whakamatao o te waka, ā, ka taea te kī ko ia te "kaitiaki whakahaere pāmahana" o te miihini. He rite tonu ki te wāhanga whakarewa me ngā paipa angiangi, engari he mahi nui tana hei pupuri i te mahi noa o te miihini.
Mai i te tirohanga mahi matua, ko te mahi matua o te pūwhakamatao he whakamatao me te whakaiti i te pāmahana o te mīhini mā te rere o te wai whakamatao. Ina mahi te mīhini, he rite ki te "whakamahana" kaha, e whakaputa ana i te nui o te wera, ā, tata ki te 30% - 40% o te wera me tuku mā te pūnaha whakamatao. Whai muri i te mimiti i te wera mai i te tinana o te rango i roto i te koti wai o te mīhini, ka rere te wai whakamatao ki te pūwhakamatao, ka haere mā roto i ngā tara whakamarara wera i roto i te pūwhakamatao, ā, mā te hauhautanga kaha o te nekehanga o te waka, te pā whakamatao rānei, ka whakawhitia te wera ki te hau. Kātahi ka hoki anō te wai whakamatao kua whakamatao ki te rere o te mīhini kia mau tonu ai te pāmahana mahi o te mīhini i roto i te awhe pai o te 85℃ - 105℃. Ka taea e tēnei tukanga te ārai i ngā hapa nui pēnei i te aukati o te piston me te whakarerekētanga o te rango i puta mai i te wera nui o te mīhini, me te ārai hoki i te hekenga o te whai huatanga nā te mahi pāmahana iti.
Haunga te mahi whakamatao taketake, he maha atu anō ngā mahi āwhina a te pūwhakamatao. Ka taea e ia te pupuri i te taurite pēhanga o te pūnaha whakamatao. Ka taea e te takirere pēhanga i runga i te taupoki pūwhakamatao, me te pēhanga o te 100 - 150 kPa, te whakaara ake i te pāmahana koropupū o te wai whakamatao ki te 120℃, ka ārai i te pakaru o ngā paipa, ā, ka haumaru ake te waka i te wā e taraiwa ana i ngā tere teitei i te raumati. Hei tāpiri, ka taea e te ārai hukapapa i roto i te pūwhakamatao te hanga i tētahi kiriata tiaki whakarewa, ka whakaiti i te waikura o te papu wai me ngā paipa, ā, ka ārai i te hekenga 30% o te pai o te whakamatao i roto i ngā tau e 3. Ko te hinu tuku aunoa o ētahi tauira, te hinu āwhina urungi, me te whakamatao o te pūnaha hauhautanga e whakawhirinaki ana ki te mahi tahi a te pūwhakamatao.
Heoi anō, ka taea hoki e tēnei "kaitiaki whakahaere pāmahana" te hē, ka puta he tūponotanga mōrearea ki te whakahaere o te waka. Ko ngā momo hē o te pūwhakamahana e whai ake nei ko ēnei.
Tuatahi, te turuturu o te wai whakamatao. Ina pakaru te radiator, ina pakaru ngā hiri, ina wetekina ngā hononga paipa, ina tawhito hoki ngā ngongo rapa, ka turuturu te wai whakamatao. Mēnā he nui te turuturu, ka puta he pata wai ki roto i te wāhanga miihini, ā, ki te kore e ranea te wai whakamatao, ka kore e pai te whakamatao o te miihini, ka piki ake te pāmahana, ka mura te rama whakatūpato pāmahana wai i runga i te papaaho. Hei tauira, ko ngā tauira pēnei i a Audi Q5 me BYD Song he ngāwari ki te raru i te turuturu o te tāke wai, ka puta pea i te kohi unahi wai nā te whakamahinga roa, te wiri i te wā e taraiwa ana ka pakaru ngā paipa, te hanganga unahi wai rānei nā te whakamahinga o te antifreeze ngoikore mō te wā roa.
Tuarua, te aukati i te pūwhakamahana. Ko te aukati o waho te nuinga o te wā e puta mai ana i ngā otaota pēnei i ngā rau, ngā pepeke, me ngā huruhuru wirou e piri ana ki ngā tara o te pūwhakamahana, ka pā ki te rere o te hau me te whakaiti i te pānga whakamatao. He maha ngā wā ka puta te aukati o roto nā te hanganga o te paru mai i te whakamahi i te ārai huka iti iho, i te unahi wai rānei i hangaia mai i te whakamahinga roa o te wai puna, ka aukati i ngā paipa whakamatao. Ka kore e pai te rere o te whakamatao i te mea ka aukatia te miihini ki te whakamarara i te wera i roto i te wā, ā, ka puta he pāmahana teitei.
Tuatoru, te wera nui o te mīhini. Koinei te whakaaturanga tika o te pakaru o te radiator. Haunga ngā take o te turuturu me te aukati i runga ake nei, ko te pakaru o te papu e arahi ana ki te korenga o te tohanga o te wai whakamatao, te aukati i te thermostat me te kore e taea te whakawhiti i waenga i te tohanga nui me te tohanga iti, me te whakaurunga o te hau ki roto i te pūnaha whakamatao hei whakararuraru i te tohanga o te wai whakamatao, ka taea katoa te whakawera i te mīhini. Ki te kore e tere te whakahaere, ka arahi pea ki ngā hua kino penei i te rewa o ngā mowhiti piston me ngā pereti takirere, me te whakarerekētanga o te rango, me te utu whakatikatika nui.
Hei karo i ngā pakaru o te tāke wai e pā kino ana ki te whakahaere o te waka, me mahi tonu ngā kaipupuri waka i ngā mahi tiaki. Me tirotiro tonu e rātou te taumata o te wai whakamatao, me te whakarite kia noho i waenga i ngā tohu "MIN" me te "MAX" i runga i te tāke wai whakawhanui. Tāpirihia te momo wai whakamatao kotahi ina kore e ranea. Kaua e whakamahi i te wai whakamatao mai i ngā waitohu rerekē. Whakakapia i ia wā, i ia wā, kia rite ki ngā whakaritenga a te pukapuka waka hei ārai i te hanganga o te unahi wai. I taua wā anō, me horoi tonu e rātou te mata o te radiator hei tango i ngā paru e piri ana, hei pupuri hoki i ngā tara wera kia ma, kia kore e araia.
Ina kite koe i ngā tohu o te pakaru o te tāke wai, pērā i te rama whakatūpato pāmahana wai o te papaaho, te hekenga o te wai whakamatao kāore e taea te whakamārama, te puta mai rānei o te mamaoa wai mā i te wāhanga miihini, me mahi tonu ngā mahi. Tuatahi, kimihia he wāhi haumaru hei tūnga i te motuka, kia tere tonu te oma o te miihini hei whakamarara i te wera, ā, whakatuwheratia te taupoki miihini hei whakanui ake i te tere o te whakamararatanga wera. Kaua e whakaweto tonu i te miihini, kaua hoki e whakatuwhera wawe i te taupoki o te radiator kia kore ai e wera. Kātahi, whakapā atu ki ngā kaimahi whakatika ngaio kia kitea ai te take o te hapa, ā, me mahi whakatikatika.
Ahakoa he iti noa te āhua o te tāke wai o te motuka, e pā ana ki te roa o te wā mahi o te miihini me te haumaru o te taraiwa o te waka. Mā te mārama ki tana mahi, te whakanui i te tiaki o ia rā, me te tere o te whakatika i ngā hapa ka taea te whakarite kia mahi tonu, kia pumau hoki tēnei "kaitiaki whakahaere pāmahana", hei tiaki i te miihini.
