He rua ngā ahunga o ngā takirere pūrerehua?

Ko te takirere pūrerehua he momo taputapu whakahaere rere me te nekehanga hurihuri hauwhā-hurihanga, e whakamahia ana i roto i ngā paipa hei whakahaere, hei wehe rānei i te rere o ngā wai (wai, hau rānei). Heoi, me whai hiri pai te takirere pūrerehua kounga pai me te mahi pai. He takirua ngā takirere pūrerehua? I te nuinga o te wā ka wehea e mātou te takirere pūrerehua ki ngā takirere pūrerehua porowhita me te takirere pūrerehua rerekē.
Ka matapakihia e mātou te takirere pūrerehua porowhita-rua e whai ake nei:

He aha te takirere pūrerehua porowhita?

Ko te takirere pūrerehua porowhita e mōhiotia ana ko ngā takirere pūrerehua noho pakari, ko ngā takirere pūrerehua kore-whakataurite rānei. Ko ōna wāhanga ko: Te tinana takirere, te kōpae, te nohoanga, te kakau me te hiri. Ko te hanganga o te takirere pūrerehua porowhita he kōpae, ā, kei waenganui o te takirere te nohoanga, te kakau rānei. Ko te tikanga ka huri te kōpae i roto i te nohoanga ngohengohe. Ka taea te whakauru i te EPDM, te NBR Viton Silicon Teflon Hypalon, te elastomer rānei.

Me pēhea te whakahaere i te takirere pūrerehua porowhita?

He tino māmā te hanganga o te takirere pūrerehua, e toru ngā tikanga whakahaere mō te whakatere: He kakau rīpene mō te rahi iti, he pouaka taputapu noke mō ngā takirere nui hei whakahaere māmā ake, me te mahi aunoa (tae atu ki ngā whakatere hiko me te hau).
Ka mahi te takirere pūrerehua mā te hurihuri i tētahi kōpae (tērā rānei he vane) i roto i te paipa hei whakahaere i te rere o te wai. Ka whakanohoia te kōpae ki runga i tētahi kakau e tika ana mā roto i te tinana takirere, ā, mā te huri i te kakau ka huri te kōpae hei whakatuwhera, hei kati rānei i te takirere. I te hurihuri o te pou, ka huri te kōpae ki te tūranga tuwhera, tuwhera rānei, kia rere noa ai te wai. I te tūranga kati, ka hurihia e te pou te kōpae hei aukati katoa i te rere me te hiri i te takirere.

He rua ngā ahunga o ngā takirere pūrerehua?

Ka taea e ngā tikanga rua-aronga te whakahaere i te rere i ngā taha e rua, e ai ki tā tātou i kōrero ai, ka taea e te kaupapa mahi a ngā takirere te whakatutuki i ngā whakaritenga. Nō reira, he rua-aronga ngā takirere pūrerehua porowhita, he maha ngā painga o te whakamahi i te takirere pūrerehua porowhita.
1 He iti ake te utu i ērā atu momo takirere nā te mea he māmā te hoahoa, he iti ake hoki ngā rauemi e hiahiatia ana mō te hanganga. Ko te nuinga o ngā penapena utu ka kitea i roto i ngā rahi takirere nui.
2. He ngāwari te whakahaere, te tāutanga me te tiaki, mā te ngāwari o te takirere pūrerehua porowhita ka māmā ake, ka tere ake te tāutanga, ka taea te whakaiti i te utu mahi. He hoahoa ngāwari, ōhanga hoki e iti ana ngā wāhanga neke, nō reira he iti ake ngā pūwāhi kakahu, ka tino whakaiti i ngā whakaritenga tiaki.
3 Ko te hoahoa māmā me te kiato, me te iti ake o te rahi kanohi ki te kanohi o te takirere pūrerehua porowhita, Ka taea te tāuta me te whakamahi i roto i ngā taiao he iti te wāhi, He iti noa te wāhi e hiahiatia ana ki te whakataurite ki ētahi atu momo takirere, pērā i ngā takirere kuaha, ngā takirere porowhita rānei, ā, nā te kiato ka māmā ake te tāutanga me te whakahaere, inā koa i roto i ngā pūnaha kapi.
4 He tere te mahi, ka whakaratohia e te hoahoa hurihuri koki-matau (90-tohu) te whakatuwheratanga me te kati tere. He mea nui tēnei āhuatanga i roto i ngā tono e hiahiatia ana te urupare tere, pērā i ngā pūnaha whakaweto ohorere, i ngā tukanga rānei me ngā whakaritenga whakahaere tika. Mā te kaha ki te whakatuwhera me te kati tere ka whakarei ake i te urupare a te pūnaha, ka tino pai ai ngā takirere pūrerehua porowhita mō te whakahaere rere me te whakahaere whakaweto/whakaweto i roto i ngā pūnaha e hiahia ana ki te wā urupare roa.

Hei whakamutunga, ko te takirere pūrerehua taha-rua me te āhuatanga hiri taha-rua nā tōna hanganga hiri ngāwari i waenganui i te nohoanga takirere me te kōpae pūrerehua, e whakarite ana i te hiri ōrite ahakoa te ahunga rere o te wai. Mā tēnei hoahoa ka whakarei ake i te mahi a te takirere me te pono i roto i te pūnaha whakahaere wai taha-rua.
