Kāpata Kīhini Whakamarumaru rapa Ngā Pūpare Ngā Kati Ngāwari
Whakaahuatanga Poto:
He huānga rapa te puna hau, he hau me te wai hei reo mahi. He mea tito mai i te paipa pēhanga, te piston, te tokotoko piston me ētahi wāhanga hono. Kī tonu tōna roto i te hauota pēhanga teitei. Nā te mea he kōhao kei roto i te piston, he ōrite ngā pēhanga hau i ngā pito e rua o te piston, engari he rerekē ngā horahanga wāhanga i ngā taha e rua o te piston.

I raro i te pānga o te pēhanga hau, ka puta te pēhanga ki te taha he iti te horahanga wāhanga, arā, ko te kaha rapa o te puna hau. Ka taea te whakarite i te rahi o te kaha rapa mā te whakarite i ngā pēhanga hauota rerekē, i ngā tokotoko piston rānei me ngā diameter rerekē. He whānui te whakamahinga o te puna hau o te kāpata rapa ki te hiki i ngā wāhanga, te tautoko, te taurite taumaha me te whakakapi i te puna miihini pai rawa atu. Ko te puna hau o te kāpata rapa he mea hanga me te hanganga hou o te tohanga ara iahiko hinu hei whakahaere i te nekehanga hau, me ngā āhuatanga pai o te arai e piki ake ana me te mārama kei te wāhi.
