I runga i te kaupapa whakahaere o te "aro ki te nama, te kiritaki tuatahi, te whai huatanga teitei me te ratonga pakeke", e mihi ana mātou ki ngā hoa o ngā āhuatanga katoa ki te mahi tahi me mātou.

Whakaahuatanga:

Ko te takirere tuku hau tere-teitei whakakotahi e honoa ana ki ngā wāhanga e rua o te takirere hau diaphragm pēhanga-teitei me te takirere tomo me te putanga pēhanga iti, kei a ia ngā mahi putanga me te whakaurunga.
Ka tukuna aunoatia e te takirere tuku hau diaphragm pehanga-tiketike te iti o te hau kua kohia i roto i te paipa ina pēhangahia te paipa.
Kāore e taea e te takirere whakauru me te takirere whakaputa iti-pēhanga te tuku i te hau i roto i te paipa ina kī tonu te paipa kau i te wai, engari ina ringihia te paipa, ina puta rānei he pēhanga kino, pērā i raro i te āhua wehenga pou wai, ka tuwhera aunoa ka tomo ki te paipa hei whakakore i te pēhanga kino.

Ko tētahi o ngā mahi matua o te takirere hau ko te tuku i te hau kua mau i roto i te pūnaha. Ina uru te wai ki ngā paipa, ka mau pea te hau ki ngā wāhi teitei ake, pērā i ngā piko, ngā wāhi teitei, me ngā tihi maunga. I te rere o te wai i roto i ngā paipa, ka kohia te hau ka hanga i ngā putunga hau, ka heke ai te pai o te mahi me te pikinga o te pēhanga.

Ngā takirere tuku hau, pērā i ngā takirere kē atu a TWS Valvengā kōpura pūrerehua noho rapa, he mahi nui anō hoki tā rātou ki te pupuri i te whai huatanga me te maeneene o te mahi a ngā paipa me ngā pūnaha e kawe ana i ngā wai. Mā te kaha ki te tuku i te hau kua mau, me te ārai i ngā āhuatanga korehau ka pai te mahi a te pūnaha, ka ārai i ngā aukati me ngā kino. Mā te mārama ki te hiranga o ngā takirere hau me te tango i ngā mahi tāutanga me te tiaki tika, ka taea e ngā kaiwhakahaere pūnaha te whakarite i te roa me te pono o ā rātou paipa me ngā pūnaha.

Ngā whakaritenga mahi:

He takirere tuku hau pēhanga iti (momo mānu + momo mānu) mā te putanga hau nui ka whakarite kia tomo mai, kia puta atu hoki te hau i te tere rere nui i te rerenga hau tere-teitei, ahakoa te rerenga hau tere-nui i konatunatua ki te kohu wai, e kore e kati i te putanga hau i mua. Ka kati noa te putanga hau i muri i te tukunga katoa o te hau.
I ngā wā katoa, mena he iti iho te pēhanga o roto o te pūnaha i te pēhanga o te hau, hei tauira, ina wehea te pou wai, ka tuwhera tonu te takirere hau ki te hau ki roto i te pūnaha hei ārai i te whakaputanga o te korehau i roto i te pūnaha. I taua wā anō, mā te whakauru i te hau i te wā e whakawātea ana te pūnaha ka tere ake te tere o te whakawātea. Kei te tihi o te takirere putanga he pereti ārai-whakariri hei whakangawari i te tukanga putanga, ka taea te ārai i ngā rerekētanga pēhanga, i ētahi atu āhuatanga kino rānei.
Ka taea e te takirere hau pēhanga-teitei te tuku i te hau kua kohia i ngā wāhi teitei o te pūnaha i te wā e pēhanga ana te pūnaha hei karo i ngā āhuatanga e whai ake nei ka pā kino ki te pūnaha: te raka o te hau, te aukati rānei o te hau.
Mā te whakanui ake i te ngaronga o te upoko o te pūnaha ka whakaiti i te tere rere, ā, ahakoa i ngā wā tino kino, ka taea te aukati katoa i te tuku wai. Ka whakanui ake i te kino o te cavitation, ka tere ake te waikura o ngā wāhanga whakarewa, ka whakanui ake i ngā rerekētanga o te pēhanga i roto i te pūnaha, ka whakanui ake i ngā hapa taputapu ine, me ngā pahūtanga hau. Ka whakapai ake i te whai huatanga o te tuku wai i roto i te whakahaere paipa.

Te kaupapa mahi:

Te tukanga mahi o te takirere hau whakakotahi ina whakakiia te paipa kau ki te wai:
1. Ringihia te hau i roto i te paipa kia maeneene ai te whakakī wai.
2. I muri i te whakawāteatanga o te hau i roto i te paipa, ka tomo te wai ki te takirere whakauru me te takirere whakaputanga pehanga iti, ā, ka hikitia te pōtae e te pūwero hei hiri i ngā putanga whakauru me te putanga whakaputanga.
3. Ko te hau e tukuna ana mai i te wai i te wā e tukuna ana te wai ka kohia ki te wāhi teitei o te pūnaha, arā, ki roto i te takirere hau hei whakakapi i te wai taketake i roto i te tinana takirere.
4. I te kohikohinga o te hau, ka heke te taumata wai i roto i te takirere hau aunoa moroiti-pēhanga-tiketike, ka heke hoki te pōro pōrewarewa, ka kumea te diaphragm hei hiri, ka huaki te putanga hau, ka tukuna te hau.
5. I muri i te tukunga o te hau, ka tomo anō te wai ki roto i te takirere hau pēhanga-tiketike, ka mānu i te pōro mānu, ka hiri i te putanga hau.
Ina whakahaerehia te pūnaha, ka haere tonu ngā huringa o ngā taahiraa 3, 4, 5 o runga ake nei
Ko te tukanga mahi a te takirere hau whakakotahi ina he iti te pēhanga i roto i te pūnaha, he iti hoki te pēhanga o te āhuarangi (e whakaputa ana i te pēhanga kino):
1. Ka taka tonu te pōro mānu o te takirere whakauru me te takirere whakaputa hau pēhanga iti hei whakatuwhera i ngā putanga whakauru me te putanga whakaputa hau.
2. Ka tomo te hau ki roto i te pūnaha mai i tēnei pūwāhi hei whakakore i te pēhanga kino me te tiaki i te pūnaha.
