Te Mārama ki ngā Pūrere Hau Whakapūngao

Ngā pūwero hau ā-pūweroka peia e ngā impeller kia huri i te tere teitei, kia puta ai te kaha porowhita o te hau. Nā te whānui me te rere o te pēhanga o te hau i roto i te impeller, ka piki ake te tere rere me te pēhanga o te hau i muri i te haerenga i roto i te impeller, ā, ka puta tonu te hau kōpeke.
Ngā Āhuatanga
He tere ngā pūwero hau ā-pūwero. Ina pumau te kawenga hau, ka mahi pūmau, ka pono hoki ngā pūwero hau ā-pūwero.
①Hanganga kiato, mama, whānuitanga nui o te putanga hau;
②He iti ake te mau o ngā wāhanga, he pono te mahi, he roa te ora;
③Kāore te putanga hau i poke i te hinu whakahinuhinu, ā, he pai te kounga o te hau e tukuna ana;
④He tino whai hua me te penapena pūngao ina nui te nekehanga.
Te kaupapa mahi
Ngā pūwero hau ā-pūweroE rua ngā wāhanga matua o te rotor: te rotor me te stator. Kei roto i te rotor he impeller me te pou. He mata kei runga i te impeller, me te kōpae taurite me tetahi wāhanga o te hiri pou. Ko te tinana matua o te stator ko te anga (puoto), ā, kei te stator hoki he diffuser, he piko, he whakahoki, he paipa putanga hau, he paipa putanga hau me tetahi wāhanga o te hiri pou. Ko te kaupapa mahi o te compressor centrifugal ko te hurihanga o te impeller i te tere tere, ka huri tahi te hau me ia. I raro i te mahi a te kaha centrifugal, ka makahia te hau ki roto i te diffuser i muri, ā, ka hangaia he rohe korehau i te impeller. I tēnei wā, ka uru te hau hou mai i waho ki te impeller. Ka huri tonu te impeller, ā, ka mimiti tonu te hau ki roto, ka maka atu, kia mau tonu ai te rere o te hau.
Ka whakawhirinaki ngā pūwero hau ā-pūwero ki ngā panonitanga o te pūngao nekeneke hei whakanui ake i te pēhanga o te hau. Ina huri te rotor me ngā mata (arā, te wira mahi), ka panaia e ngā mata te hau kia huri, ka whakawhiti i te mahi ki te hau, ā, ka whiwhi te hau i te pūngao nekeneke. I muri i te urunga ki te wāhanga stator, nā te pānga whānui o te stator, ka hurihia te pane pēhanga pūngao tere ki te pēhanga e hiahiatia ana, ka whakaitihia te tere, ka whakanuia te pēhanga. I taua wā anō, ka whakamahia te pānga ārahi o te wāhanga stator hei tomo ki te wāhanga e whai ake nei o te impeller kia piki tonu te pēhanga, ā, ka mutu ka tukuna e te volute. Mō ia pūwero, kia tutuki ai te pēhanga hoahoa e hiahiatia ana, he rerekē te maha o ngā wāhanga me ngā wāhanga o ia pūwero, ā, he maha ngā rango kei roto.
