Ka kiia ko te mīhini turbo hei whakawhiti i te pūngao ki te rere tonu o te wai mā te mahi hihiri o ngā mata i runga i te impeller hurihuri, hei whakatairanga rānei i te hurihuri o ngā mata mā te pūngao mai i te wai. I roto i te mīhini turbo, ka mahi ngā mata hurihuri i te mahi pai, kino rānei ki runga i te wai, ka whakanui, ka whakaiti rānei i tōna pēhanga. E rua ngā wāhanga matua o te mīhini turbo: ko tētahi ko te mīhini mahi e mimiti ai te wai i te mana hei whakanui i te pane pēhanga, i te pane wai rānei, pērā i ngā papu vane me ngā hauhautanga; ko tētahi ko te neke matua, e whakawhanui ai te wai, e whakaiti ai i te pēhanga, e whakaputa ai rānei te pane wai i te mana, pērā i ngā tāwhana mamaoa me ngā tāwhana wai. Ka kiia te neke matua ko te tāwhana, ā, ko te mīhini mahi ka kiia ko te mīhini wai mata.
E ai ki ngā mātāpono mahi rerekē o te pā, ka taea te wehewehe ki te momo mata me te momo rōrahi, i roto i ēnei ka taea te wehewehe i te momo mata ki te rere tuaka, te momo porotītaha me te rere whakauru. E ai ki te pēhanga o te pā, ka taea te wehewehe ki te pupuhi, te kōpeke me te mānumanu. Ko tā mātou paerewa ahumahi mīhini o nāianei JB/T2977-92 e kī ana: Ko te pā e pā ana ki te pā ko tōna tomokanga he āhua tomokanga hau paerewa, ko tōna pēhanga putanga (pēhanga ine) he iti iho i te 0.015MPa; Ko te pēhanga putanga (pēhanga ine) i waenga i te 0.015MPa me te 0.2MPa ka kiia ko te pupuhi; Ko te pēhanga putanga (pēhanga ine) neke atu i te 0.2MPa ka kiia he kōpeke.
Ko ngā wāhanga matua o te pupuhi ko: te volute, te collector me te impeller.
Ka taea e te kaikohi te tuku i te hau ki te impeller, ā, ka whakamanahia te rere o te impeller e te āhua o te kaikohi. He maha ngā momo āhua o te kaikohi, ko te nuinga: te oko, te koeko, te koeko, te pewa, te pewa pewa, te koeko pewa me ētahi atu.
Ko te nuinga o te wā, e whā ngā wāhanga o te impeller, arā, te uhi wira, te mata, me te kōpae poutū, ā, ko tōna hanganga he mea whakarewa me te hononga rivet. E ai ki te putanga o te impeller o ngā koki tāutanga rerekē, ka taea te wehewehe ki ngā koki radial, mua, me muri e toru. Ko te impeller te wāhanga tino nui o te pā centrifugal, e peia ana e te nekehanga matua, koia te ngākau o te turinachinery centrifugal, e kawenga ana mō te tukanga tuku pūngao e whakaahuatia ana e te whārite Euler. Ka pāngia te rere o roto i te impeller centrifugal e te hurihuri o te impeller me te piko o te mata, ā, ka haere tahi me te whakahekenga, te hokinga mai me ngā āhuatanga rere tuarua, kia tino uaua ai te rere o roto i te impeller. Ka pā tika te āhua rere o roto i te impeller ki te mahi aerodynamic me te whai huatanga o te wāhanga katoa, tae atu ki te mīhini katoa.
Ko te volute te mea nui hei kohikohi i te hau e puta mai ana i te impeller. I taua wā anō, ka taea te huri i te kaha nekeneke o te hau hei kaha pēhanga pumau o te hau mā te whakaiti i te tere o te hau, ā, ka taea te ārahi i te hau kia puta i te putanga volute. Hei mīhini turbo wai, he tikanga tino whai hua tēnei hei whakapai ake i te mahi me te whai huatanga o te pupuhi mā te ako i tōna mara rere o roto. Hei mārama ki te āhua rere tūturu i roto i te pupuhi centrifugal me te whakapai ake i te hoahoa o te impeller me te volute hei whakapai ake i te mahi me te whai huatanga, he maha ngā tātaritanga ariā taketake, ngā rangahau whakamātautau me te whakatauira tau o te impeller centrifugal me te volute.
