He whānui rawa te whānuitanga o te whakamahinga o te puna hau. I tēnei rā, ka arotakehia e Tieying tētahi tātaritanga poto mō te whakamahinga opuna haui roto i te mara ahumahi, kia mārama ake ai te katoa ki te puna hau.
Hei whakahaere i te mahi hiki o ngā taupoki, ngā taupoki me ngā takirere, he kōwhiringa pai te whakamahi i ngā puna hau ahumahi. Ko ngā puna hau kowiri tira te mea e tika ana mō ngā whakaritenga motuhake o te ahumahi kai, te hangarau hauora, te hanga kaipuke, te hangarau taiao rānei.
Puna hau ahumahi kowiri tiraKo ngā mea i hangaia mai i ngā rauemi koranu V2A, V4A rānei, kāore i te whakaaetia kia whakamahia i roto i te umanga kai anake, engari ka taea hoki te whakatutuki i ngā whakaritenga o ngā whakaritenga akuaku me ētahi atu kāwai. He pai tēnei puna hau kowiri tira mō te umanga kai, te hangarau hauora, te hanga kaipuke, te hangarau taiao me ētahi atu umanga motuhake.
Ko te whānui o te anga o tēnei momo huānga whakamātao i hangaia ki te maitai kore waikura he 15-40mm, ā, he rerekē te roa o te whiu me te kaha o te hiki. Hei whiwhi whakaaetanga tono mai i te umanga kai me te umanga hangarau taiao, ko tepuna hau kowiri tirakua whakakīia ki te hinu motuhake hei whakaiti i te wiri i te tūranga marino o te pito.
He rite tonu te kaupapa mahi o ngā momo puna hau katoa, arā, ka whakakīia te pūnaha kati-ā-unoa ki te hauota pēhanga, kāore he tiaki, ā, ka rere te hauākoni mā roto i te kōhao whakatere i runga i te piston ina katia te taupoki. Mā tēnei ka puta he tere whakauru piston tuturu, ā, ka whakarite hoki i te aukati.
Ina neke te piston ki waho, ka tau mārire pea te hinu kua whakakīia ki te tūranga pito. Nā reira, ka mahi noa te whakamātao pito ina tāutahia te puna hau ki raro i runga i te tokotoko piston. Ka hoki mai te hauota ina tīmata te pūnaha, ā, ka tautoko i te mahi ā-ringa e haere tahi ana. Ki te whakatauritea ki ētahi atu tikanga whakaiti wiri, ko te whakarerekētanga pai o tēnei kaupapa whakaiti wiri e whakaatuhia ana i roto i te āheinga ka whakakīia ngā puna hau ki te hauota.
Mō tehangaKo te puna hau e whakamahia ana mō te hiki i te taupoki, te tuku rānei i ngā poti ora i roto i te umanga hanga kaipuke, he kowiri tira te V4A he nui ake te ihirangi molybdenum, ā, he ātete ki te waikura me te horo wai moana, he rerekē tēnei i te koranu V2A. Ka taea e ngā kaiwhakamahi te tāuta i ngā puna hau ki roto i ngā mīhini me ngā taputapu mā rātou anō me ngā taputapu e rite ana.
