Ko te takirere pūrerehua kati puhoi whakahaere waipēhi he taputapu whakahaere paipa matatau i te kāinga me tāwāhi. Ka tāutahia te nuinga ki te tomokanga tāpine o te teihana hiko waipēhi, ā, ka whakamahia hei takirere tomokanga tāpine; ka tāutahia rānei ki te whare tiaki wai, ki te hiko, ki te puna wai me te putanga papu rerenga wai, hei utu mō te takirere tirotiro me te takirere kuaha. I te wā e mahi ana, ka mahi tahi te takirere me te miihini matua o te paipa, kia rite ki te kaupapa o te tukanga whakawhiti waipēhi, ā, mā roto i ngā tikanga whakatuwhera me te kati kua whakaritea, ka taea e ia te whakatutuki i te tapahi pono o te paipa, te whakakore i te hama wai i roto i te paipa, ā, ka whai wāhi ki te tiaki i te haumaru o te pūnaha paipa.

Te kaupapa mahi

Ko te kaha kati rāhui o te hama taumaha whakahaere waipēhi kati puhoi tirotiro pūrerehua he kaha pūmanawa hama taumaha, e wehea ana ki te hama taumaha pupuri pēhanga aunoa whakahaere waipēhi kati puhoi tirotiro pūrerehua (e kiia nei i muri nei ko te momo hama taumaha pupuri pēhanga) me te hama taumaha raka aunoa whakahaere waipēhi pupuri pēhanga puhoi tirotiro pūrerehua (e kiia nei i muri nei ko te momo hama taumaha raka). Ko ngā tikanga ratonga ko te nuinga o te āhua o te papu tohanga, te āhua o te papu rere tuaka me te āhua o te tāpine.

Āhua mahi o te papu torengi me te whakatuwheratanga o te takirere (tae atu ki te papu rere whakauru torengi): tīmatahia te papu i te tuatahi, kātahi ka whakatuwhera i te takirere i muri i te whakaroa i te wā kua whakaritea.

Āhua mahi o te papu rere axial takirere tuwhera (tae atu ki te papu rere whakauru axial): whakatuwherahia te takirere papu i te wā kotahi, whakatuwherahia rānei te takirere ki tētahi koki i te tuatahi, kātahi ka tīmata te papu.

Āhua mahi o te tāpine whakatuwhera takirere: whakatuwheratia te takirere karo tuatahi hei taurite i te pēhanga, kātahi ka whakatuwheratia te takirere, kātahi ka whakatuwheratia te tāpine.

Ko te tikanga me kati te takirere i te wā kotahi e kati ana, e kore rānei e hiko i raro i ngā tikanga mahi rerekē.

Ko te kaupapa matua o te mahi hiko-waipēhi e whai ake nei:

Ina whakatuwheratia te takirere, ka huri te takirere solenoid, ka tīmata te papu hinu, ā, ka tomo te hinu waipēhi ki roto i te rango hinu mā te takirere whakahaere rere me te ngongo pēhanga teitei hei pana i te piston me te taraiwa i te rīpene e hono ana ki a ia hei hiki i te hama taumaha hei whakatuwhera i te takirere. I muri i te whakatuwheratanga o te takirere ki tōna tūranga, ka tīmata te pūnaha pupuri pēhanga aunoa; ka haere tonu te motuka ki te utu i te kaiwhakaemi. Ina tae te pēhanga ki te pūwāhi tautuhinga pēhanga teitei, ka mutu te papu hinu. Ka taea te whakarite i te wā whakatuwheratanga o te takirere mā te huri i te wira ringaringa o te takirere whakahaere rere, ā, ko te awhe whakarite he 10 ~ 90 hēkona.

Ina turuturu te pūnaha, ā, ka heke te pēhanga ki te pūwāhi pēhanga iti, ka tīmata aunoa te motuka papu hinu, ā, ka mutu i muri i te taenga ki te pūwāhi pēhanga teitei.

Ina kati te takirere, ka huri te takirere solenoid, ka hoki te hinu pēhanga i roto i te rango hinu ki te tāke hinu mā te takirere rere tere me te puhoi, te ngongo pēhanga teitei me te takirere solenoid, ka taka te hama taumaha ki raro, ā, ka panaia e te tokotoko hono te pereti pūrerehua kia huri hei kati i te takirere, kia tere ai te tapahi i te nuinga o te rere o te wai tata ki te 70% o te whiu o mua; ka kati pōturi te 30% whakamutunga o te whiu. Ka taea te whakarite i te koki o te kati tere me te puhoi me te wā ārai o ia wāhanga kia rite ki ngā āhuatanga mahi tūturu o te paipa hei whakakore i te hama wai i roto i te paipa; Ko te wā whakatikatika he 2 hēkona ki te 25 hēkona mō te kati tere me te 6 hēkona ki te 90 hēkona mō te kati pōturi.

I te tukanga whakatuwheratanga me te katinga, ka taea te aukati i te takirere i tetahi tūranga waenga mā te pēhi i te pātene aukati. Ko te mahi aukati te mea nui hei whakatika i ngā hapa pūnaha.

Ko te papu ā-ringa te mea e whakamahia ana mō te whakatikatika i te pūnaha. Mēnā kāore he hiko, kāore rānei e taea e te papu hinu te mahi tika, mā te rūrū i te papu ā-ringa ka taea hoki te whakatuwhera i te takirere me te pupuri i te pēhanga o te pūnaha. Whakatuwheratia te takirere aukati e kati noa ana, i raro i te mahi a te kaha pūmanawa hama me te taipana wai, ka hurihia te pereti pūrerehua e te tokotoko hono hei kati i te takirere.
