Ko te ngoikoretanga o te takirere pūrerehua hiri rapa, ina whakamahia mō te whakakaha, ka puta te cavitation nā te whakamahinga hē, ka pakaru te nohoanga rapa. Nā tēnei take, kua whakawhanakehia ngā takirere pūrerehua hiri-whakarewa o te ao, ā, kua whakaitihia te rohe cavitation. I ngā tau tata nei, kua whakawhanakehia hoki e tōku whenua ngā takirere pūrerehua hiri-whakarewa. I Hapani, kua whakawhanakehia hoki i ngā tau tata nei ngā takirere pūrerehua āhua-heru me te ātete cavitation, te wiri iti me te haruru iti.
Ko te roanga o te ora o te nohoanga hiri o te takirere pūrerehua he 15-20 tau mō te rapa, ā, 80-90 tau mō te konganuku i raro i ngā āhuatanga noa. Heoi, ko te kōwhiringa tika ka whakawhirinaki ki ngā whakaritenga o ngā āhuatanga mahi.
Ko te whanaungatanga i waenga i te tohu whakatuwheratanga o te takirere pūrerehua hiri whakarewa me te tere rere ka huri noa i te rārangi. Mena ka whakamahia hei whakahaere i te rere, ka pā tata hoki ōna āhuatanga rere ki te ātete rere o ngā paipa. Hei tauira, e rua ngā paipa kua tāutahia me te diameter me te āhua o te takirere, engari he rerekē te tauwehenga ngaronga o te paipa, ā, ka tino rerekē hoki te tere rere o te takirere. Mena kei roto te takirere i te āhua me te whānuitanga nui o te throttle, ka ngāwari te tuara o te pereti takirere ki te cavitation, ka kino pea te takirere. I te nuinga o te wā, ka whakamahia i waho o te 15°.
Ina kei waenganui te hiri whakarewa mō te pūrerehua, ka pokapū te āhua o te whakatuwheratanga i hangaia e te tinana takirere me te pito o mua o te pereti pūrerehua ki te kakau takirere, ā, ka hangaia ngā taha e rua hei whakaoti i ngā āhua rerekē. Ka neke te pito o mua o te pereti pūrerehua i tetahi taha ki te ahunga o te wai e rere ana, ā, ka rere whakamuri tetahi taha. Nō reira, ka hangaia e tetahi taha o te tinana takirere me te pereti takirere he whakatuwheratanga rite ki te pūwero, ā, he rite tetahi taha ki te whakatuwheratanga o te pūwero. He tere ake te rere o te taha pūwero i te taha o te pūwero, ā, ka puta he pēhanga kino mai i te takirere taha pūwero, he maha ngā wā ka taka ngā hiri rapa.
He rerekē ngā uara o te taipana whakahaere o te whakatikatika pūrerehua hiri whakarewa nā te rerekētanga o ngā ahunga whakatuwheratanga me te kati o te takirere. Mō te takirere pūrerehua whakapae, inā koa te takirere pūrerehua whānui-rahi, nā te hohonu o te wai, kāore e taea te wareware i te taipana i hangaia e te rerekētanga i waenga i ngā pane wai o runga me raro o te pou takirere. Hei tāpiri, ina tāutahia he tuke ki te taha tomo o te takirere, ka puta he rere whakarara, ā, ka piki ake te taipana. Ina kei waenganui te takirere, me raka-ake te pūnaha whakahaere nā te mahi a te taipana rere wai.
