Kua roa a Pierburg e whakawhanake ana i ngā papu korehau mō ngā whakakaha pērai. Mā te tauira EVP40 o nāianei, kei te tuku te kaiwhakarato i tētahi kōwhiringa hiko e mahi ana i runga i te tono, ā, e whakatakoto ana i ngā paerewa teitei mō te pakari, te ātete ki te pāmahana me te haruru.
Ka taea te whakamahi i te EVP40 i roto i ngā waka ranu me ngā waka hiko, tae atu ki ngā waka me ngā raina taraiwa tuku iho. Ko ngā wāhi whakaputa ko te wheketere o Pierburg i Hartha, Tiamana, me te hononga tahi o Pierburg Huayu Pump Technology (PHP) i Shanghai, Haina.
Mō ngā miihini penehīni hou, ka whakaratohia e te papu korehau hiko he taumata korehau e ranea ana mō te aukati haumaru me te ngāwari me te kore e ngaro te mana tuturu o te papu miihini. Mā te hanga i te papu kia motuhake mai i te miihini, ka taea e te pūnaha te whakanui ake i te pai o te mahi, mai i te aratau tīmatanga/mutu roa (rere) ki te aratau taraiwa hiko katoa (aratau EV).
I roto i tētahi waka hiko kounga-nui (BEV) kiato, i whakaatu te papu i te mahi tino pai i ngā whakamātautau whenua teitei i te huarahi maunga o Grossglockner i Austria.
I roto i te hoahoa o te EVP 40, i whakanui a Pierburg i te pono me te roa o te ora, nā te mea me whakamana te whakahaere o te waka i ngā wā katoa, ā, ko te pūnaha aukati te mea nui rawa atu. Ko te pakari me te pumau hoki ngā take matua, nō reira me whai i tētahi kaupapa whakamātautau whānui te papu i raro i ngā āhuatanga katoa, tae atu ki ngā whakamātautau pāmahana mai i te -40 °C ki te +120 °C. Mō te whai huatanga e tika ana, i hangaia he motuka paraihe hou, pakari, kāore he hikohiko.
Nā te mea e whakamahia ana te papu korehau hiko i roto i ngā waka ranu me ngā waka hiko, tae atu ki ngā motuka he raina taraiwa tuku iho, me iti rawa te haruru e puta mai ana i te pūnaha papu kia kore ai e rangona i te wā e taraiwa ana. Nā te mea he whanaketanga ā-roto katoa te papu me te motuka whakauru, i kitea ngā otinga whakapiri māmā, ā, i karohia ngā wāhanga wetewete wiri utu nui, nō reira he pai te wetewete haruru o te hanganga me te iti o ngā tukunga haruru hau i roto i te pūnaha papu katoa.
Mā te takirere kore-hoki kua whakauruhia ka nui ake te uara mō te kiritaki, ka māmā ake, ka iti ake hoki te utu mō te tāuta i te EVP ki roto i te waka. Mā te tāutanga ngāwari, motuhake i ētahi atu wāhanga, ka taea te whakatau i ngā raruraru e puta mai ana i te wāhi tāutanga kuiti.
Papamuri. He iti te utu o ngā papu korehau miihini e hono tika ana ki te miihini mura, engari ko te ngoikoretanga ko te rere tonu i te wā e whakahaerehia ana te waka me te kore e hiahiatia, ahakoa i ngā tere teitei, i runga i te aratau whakahaere.
I tētahi atu taha, ka whakawetohia te papu korehau hiko mēnā kāore ngā parai e whakamahia. Ka whakaitihia te whakapaunga wahie me ngā tukunga hau. Hei tāpiri, mā te korenga o te papu miihini ka whakaitihia te kawenga ki te pūnaha whakahinuhinu hinu miihini, nā te mea kāore he hinu tāpiri e whakahinuhinu ana i te papu korehau. Nō reira, ka taea te whakaiti i te papu hinu, ā, ka piki ake te pai o te raina taraiwa.
Ko tētahi atu painga ko te pikinga o te pēhanga hinu i te wāhi tāutanga taketake o te papu korehau mīhini—i te nuinga o te wā i te pane rango. Mō ngā papu korehau hiko ranu, ka taea e ngā papu korehau hiko te taraiwa hiko katoa me te whakaweto i te miihini mura, me te pupuri tonu i te pikinga katoa o te pēhi. Ka taea hoki e ēnei papu te aratau "rere" e whakawetohia ai te raina taraiwa, ā, ka penapenahia he pūngao tāpiri nā te whakaiti i ngā ātete i roto i te raina taraiwa (te mahi tīmatanga/mutu roa).
