Ko te mahi matua o te papu wai waka
I roto i te pūnaha whakahaere o te mīhini waka, ko te papu wai te "ngākau mana" o te pūnaha whakamatao. Ka pā tika tana mahi ki te roa o te ora me te pumau o te mahi a te mīhini.
I te wā e mahi ana te mīhini, ka taea e te pāmahana i roto i te rango nā te tahunga wahie te eke ki runga ake i te 2000°C. Ki te kore e whakamataohia i te wā tika, ka pāngia ngā wāhanga e te whānui wera, ā, ka piri pea, ka heke te kaha miihini, ā, ka pakaru te hinu whakahinuhinu nā te pāmahana teitei. Ā tōna wā, ka pakaru te mīhini. Ko te mahi matua o te papu wai ko te whakanui ake i te pēhanga o te wai whakamatao, kia taea ai e ia te huri haere tonu i roto i te pūnaha whakamatao. Ka honoa ki te porowhita o te mīhini mā te pūreirei. I te wā e mahi ana te mīhini, ka akiaki i te impeller papu wai kia huri. I raro i te mahi a te kaha centrifugal, ka whiua te wai whakamatao ki te taha o te tinana papu ka panaia ki roto i te ara wai o te mīhini. I taua wā anō, ka hangaia he wāhi pēhanga iti ki waenganui o te impeller, ka kukume i te wai whakamatao kua whakamataohia mai i te radiator ki roto, ka tutuki ai te whakawhiti i waenga i te "tohanga iti" me te "tohanga nui": i te wā e makariri ana te mīhini, ka huri noa te wai whakamatao i roto i te mīhini hei āwhina i a ia kia tere te eke ki te pāmahana mahi tino pai; Ina eke te pāmahana ki runga ake i te 80°C, ka huaki te thermostat, ka rere te wai whakamatao ki roto i te radiator, ka whakamahia te rere o te hau i te wā e neke ana te waka hei tango i te wera, kia mau tonu ai te miihini ki te awhe mahi pai o te 85°C - 95°C.
Hei tāpiritanga, ka taea hoki e te papu wai te whakarei ake i te whai huatanga whānui o te pūnaha whakamatao. Ka whakarite kia rere te wai whakamatao i roto i te poraka rango miihini, te pane rango me ētahi atu wāhanga matua i te pēhanga me te tere rere e tika ana, ka tangohia te wera kia ōrite, ka karo hoki i te whakarerekētanga o te rango me te horo i puta mai i te wera nui o te rohe. Mō ngā miihini turbocharged, me whakarato hoki te papu wai i te whakamatao mō te turbocharger, kia mau ai tana mahi i roto i ngā taiao pāmahana teitei me te tere teitei.
Ngā hapa noa me te tautuhi i ngā papu wai o ngā waka
Ka roa te mahi a ngā papu wai waka i roto i ngā taiao pāmahana teitei me te pēhanga teitei, ā, ka pakaru pea nā te pakaru me te waikura. Ko ngā raruraru noa ko ēnei momo:
Te turuturu o te wai whakamatao
Ko tētahi tēnei o ngā hapa tino noa o te papu wai. Ko te nuinga o te take he tawhito ngā hiri wai, he pakaru ngā hiri hiri, he pakaru rānei ngā tinana papu. He wāhanga matua te hiri wai hei ārai i te turuturu o te wai whakamatao. Mā te rumaki roa ki roto i te wai whakamatao ka waikura, ka ngaro te mahi hiri, ā, ka turuturu te wai whakamatao mai i te hononga i waenga i te pou papu me te tinana papu, ka waiho he tohu māwhero, kakariki me ētahi atu tohu wai whakamatao ki raro o te miihini, ki ngā kōhao hau rānei o te papu wai. Mena ka pakaru te tinana papu nā te hukapapa hotoke, nā ngā hapa whakarewa rānei, ka nui te turuturu, ka tere te heke o te taumata wai whakamatao, ā, i ngā wā kino, ka puta te āhuatanga "kohua nui" o te miihini.
Te whakaiti i te kaha o te tohanga toto
Mā te kakahu, te wetekina, te paheke rānei o te impeller papu wai, te kakahu rānei o te whitiki, ka whakaiti i te pai o te rere o te wai whakamatao. I tēnei wā, ka piki te pāmahana wai o te mīhini i runga i te āhua rerekē, ka mura te rama whakatūpato mō te pāmahana wai i runga i te papaaho, ā, ka maringi pea te wai whakamatao mai i te taupoki o te tāke wai, ka hua ake te āhuatanga "kohua". I ngā taiao raumati wera, i raro rānei i ngā āhuatanga taumaha pēnei i te piki pukepuke, te hipa rānei, he mārama ake te raruraru. Tērā pea ka pāngia ētahi waka e te piki me te heke o te pāmahana wai, e puta mai ana i te mahi koretake o te impeller me te rere koretake o te wai whakamatao.
Haruru rerekē me te wiri oma
Ina pakaru ngā peera o te papu wai, ina whakaranua rānei ngā matū ke ki roto, ka puta he tangi koi o te waku, he tangi pā i ia wā, ā, ka piki ake te haruru i te pikinga o te tere o te miihini. Mena ka wetekina, ka pakaru rānei te impeller, ka kore e taurite te mahi a te papu wai, ka hua ake te wiri o te miihini, inā koa ka kitea i te wā e noho mangere ana. Hei tāpiri, ko te pikinga o te ātete i roto i te hurihanga o te papu wai ka pā ki te pumau o te tere hurihanga o te miihini. I te tīmatanga makariri i te takurua, tera pea ka rerekē te tere, ka mutu rānei te miihini.
Whitiki pakaru
Ki te mau ngā peera o te papu wai, ki te mau rānei te impeller, ka tino piki ake te kawenga i runga i te whitiki tuku, ā, i ngā wā tino kino, ka whati te whitiki, ka mutu te mahi a te whakaputa hiko, te compressor hauhautanga me ētahi atu wāhanga, ka ngaro te urungi hiko me te pūnaha hiko o te waka, ā, ka puta he mōrearea taraiwa.
Ngā take me te ārai i te pakaru o te papu wai
Ko te puta mai o ngā pakaru o te papu wai ehara i te mea ko ngā āhuatanga tawhito anake engari ko te whakamahinga hē me te tiaki hoki. Ko te pakaru o ngā mīhini tētahi o ngā tino take. Ka pakaru haere ngā wāhanga pēnei i ngā peera me ngā impeller i roto i te wā, ā, mā te pakaru o te hinu whakahinuhinu ka tere ake tēnei tukanga. Mena ka nui ake te taumata pH o te wai whakamatao i te paerewa, ka waikura te hiri wai me te tinana papu, ka pakaru te hiri, ka kino rānei ngā wāhanga. I te takurua, ki te kore te wai e ringihia i te wā tika, ki te whakamahia rānei he ārai hukapapa kounga iti, ka tio pea te tinana papu ka pakaru. Hei tāpiri, mā te nui rawa o te whitiki me te tāutanga hē ka pakaru wawe te peera papu.
I roto i ngā mahi tiaki o ia rā, me tirotiro tonu ngā kaipupuri waka i te taumata me te āhua o te wai whakamatao. Me whakakapi te wai ārai huka e tutuki ana i te paerewa i ia 2 tau, i ia 40,000 kiromita rānei, kia kore ai e whakamahia te wai puna, ētahi atu wai rānei kei roto he paru. I roto i ia mahi tiaki, me tirotiro e ngā kaimahi tiaki te kukū o te whitiki me te pakaru o te papu wai. Mena ka kitea he pakaru, he tawhito rānei, whakakapia i te wā tika. Kia tūpato ki te tirotiro mena kei te kitea he tohu turuturu wai i raro i te miihini. I te tīmatanga o te waka, kia tūpato mena kei te kitea he haruru rerekē i te wāhanga o mua. Kia kitea he pāmahana wai rerekē, he tohu turuturu wai rānei, kati tonu te waka mō te tiaki kia kore ai e huri ngā raruraru iti ki ngā raruraru nui pēnei i te pakaru o te miihini.
