Ko te pūkaha hiko wai pūwero rua he mea hanga mai i te tāpine pelton moroiti me te pūkaha e mau ana i roto i te pou kotahi. Ko te nuinga o te mea he paipa ārahi tomo, he impeller hurihuri, he pou matua, he turanga, he takirere whakatikatika, he peera, he taupoki, he hiri me ētahi atu. I te wa e arahina ana te wai pēhanga teitei ki roto i te paipa tomo, ka whakawhitia te kaha pēhanga teitei ki te kaha hihiri tere teitei i roto i te rohe o te pūkaha ārahi. Ko te wai tere teitei e wehe atu ana i te

Ka pā te pūwero ki te impeller o te tāpine, ā, ka akiaki i te rotor kia huri.

Kei te whakairihia poutū te tāpine Pelton rua-pūwero. Ko ōna painga e whai ake nei:

1. He paipa e tomo mai ana, he ngāwari ki te tāuta;

2. Kei roto i te pou kotahi te tāhū me te whakaputa hiko, he kiato, he ngāwari hoki te kawe me te tāuta;

3. He pai te taurite o te kaha porowhita mā te hoahoa pūwero takirua. E 3 ngā pēhanga

kei roto i te mīhini whakaputa hiko o te tāpine, nō reira he roa te roa o te ora o te pūnga.

4. Ka taea te whakaputa ngāwari i te mana whakatauranga nā te nui o te whai huatanga o te tāpine.

5. Ki te whakaritea ki te tāpine rere radial, he teitei te whai huatanga, ā, kāore e hiahiatia he whakaritenga o ngā hononga. Kāore he take e manukanuka ai mō te hē o te whakaritenga o ngā hononga!!!
