He aha ngā āhuatanga e whai mātai ana ina whiriwhiria ngā hononga mō ngā wāhanga o te punaha waihanga?

Te Liliunatanga i te Rōlolo o ngā Kōpiko ki te Mahi o te Pūnaha Whakapua

Me pēhea ngā kōpiko e whakarato ana i ngā whatunga whakapua takitahi me te āhua

Ko ngā kōpae he wāhi matua nui ki te hanga i ngā tūmau whakapau mātai e āki ai, e huri ai ā rātou here whenua ake i te wā e huri haere ana ngā herekoreti tuarangi. Ka kitea e ngā kaiwhenua he pai ngā hononga paerewa nei ina tāpiri ana i ētahi wāhanga hou ki tō rātou punaha, nā te iti iho o te mahi tīmatanga. I ētahi rangahau i te tau whakamutunga ka kitea ko te wā tīmatanga ka heke pea ake ki te toru haurua menē rārangi kōpae i te wehe katoa. Ko te vantex nui ko te taea e te punaha te whanaketanga pakitara, kia rite ki ngā wa kua tīmata te taraiwa, ki ngā wāhanga hou rānei e wātea mai ana i te māke. He nui ngā kaiwhenua e mihi nei ki tēnei maruaroa nā te penihana e peniana ana, ā, kei te pumau tonu te tukatuka waimātai mō ngā rongoā rerekē.

Te tikanga o ngā kōpae ki te pupuri i te kintanga o te punaha me te tukanga o te rere

Kia āhua hāpai ngā kōpiko e whai tika ana kia pāwhara te rere o te wai mā te whakaiti i ngā arorangi me ngā pēpihi e pakaru ana i runga i ngā wāhanga hononga. Kāore ngā tikanga herehere e rere ana i te wai ka riro pea ki te 14,000 litra/ekare ia tau ki ngā punaha whakapua (FAO 2022), ka tiakina te maru o te wai, ka whakarite hoki i te wehenga kotahi ki ngā mara.

Ngā hinganga noa rahi pea nā te whakamahinga kore tika o ngā kōpiko ki ngā takotoranga whakapua

Ko ngā kōpiko e kore nei e tika, i te nuinga o te wā e hāngai ana ki te 37% o ngā hinganga māmā o ngā raina whakapua, e ai ki tētahi rangahau 2024 mō ngā 120 mara. Ko ngā kōpiko paraire e whakamahia ana me ngā tuipiri pūreke kīato e huritau ana te wearu, ko ngā taunga iti ake i ngā wāhi pēpihi teitei e wātea ana, ā, he māngai noa iho te pāwhara me te parihau oneone.

Te hiahia haere tonu ki ngā kōpiko tere-hono ki ngā punaha whakapua mātau

Ko ngā kōpae huinga marino ka tūhono ā-nau inaianei ki te 58% o ngā whakaurunga hokohoko hou nā te huinga māmā ki ngā inihini IoT me ngā rāwekenga rohe aunoa. Mā ēnei hononga kore taputapu e taea ai te whakarerekē tere mō te whakapai pakuaka me te pupuri i te mahi ki ngā pēhi tae atu ki te 125 PSI, āwhina ana i ngā rautaki whakapōngia ōrite-tere.

Te whakauru i te mahi a te kōpae ki ngā whāinga hoahoa punaha whakapōngia

Ko te tīpako tika kōpae e taurite ana i ngā matua take e whā: te angamira ki ngā waiwhitinga (te nekehanga iti rawa 90 PSI), te whai wāhi ki ngā mātai ahumahi, te pūmau UV mō te whakamahi ki waho, me te tere whakauru (he iti ake i te 90 sekene pera ko te hononga). Ina uru ana ki te hoahoa punaha, ka heke te utu tiaki umanga umanga 32% i runga i te rima tau, i te whakapai ake i te tiaki wai.

Te whakatakoto i te Rahi me te Momo Kōpae ki ngā Taipitopito Poi Whakapōngia

Te ine i te Tātaitanga Tāwāhi Poi mō te Takotoranga Tika o te Kōpae

He mea nui ngā kāpire e matara ana ina whakamahia ana hei ine i te tawhānui o waho o tētahi pīpoi ki ētahi wāhi rerekē i tōna roa, nā te whānuitanga o te hanga e āwhina ana ki te rerekētanga. I whakaatu ngā pūrongo a te ahumahi i te tau 2025 i ētahi raruraru i heke ai te iti noa o te mōhio – i kitea e kātata ana tētahi wāhi iti noa o 1.125 mm kei waenganui i tētahi hononga 17 mm me te pīpoi e hiahiatia ana ko 15.875 mm, ka taea e te paru te uru atu, ka muimui i ngā kaihāpara i te tata ki te toru tekau mano karihi i ngā tanumaero. Ina mahi ana ki ngā pīpoi PVC kikii, he pai te ine i ia tāwaenga, tāmata anoo hoki i waenganui. Engari me nui ake te whai whakaaro ki ngā pīpoi polyethylene maroke. Ko te tikanga pai ko te tirotiro i te rahi i ia tekau mā toru mitarā pea kia kitea ngā āhuatanga kore tika i mua i te tupono haere ake i ētahi raruraru nui ake.

Te Arataki Ngātahi hei Whiriwhiri i ngā Huinga e ū ana ki te Rahi o te Pīpoi

1. Whakamātau i te tōporetanga o te OD : Kaua e whakaae ki tētahi rerekētanga neke atu i te 0.5mm i te tawhānui o te pīpoi
2. Whakapūmau i ngā here here : Kōwhiria ngā kōpua e neke ake ana i te 20% te pēhanga rū torotoro (hei tauira, ngā kōpua 60 PSI mō ngā punaha 50 PSI)
3. Whakamātau i te whānuitanga o te wera : Tukuna he herenga roa 3–5% mō ngā matapae e noho ana i ngā wera e teke ake i te 95°F

Tōiriiri vs. Tiamita Pīpoi: Whakaputa i ngā huringa hē hōhonu

Ko te whakamahinga hē o ngā tapanga ingoatanga e 65% te take o ngā rūrekenga i ngā pūnaha mara, ā, e ai ki Whakahaerenga Wai Ahuwhenua (2023).

Ngā Kuputipu Barbed ki te Kuputipu Compression mō ngā Tūpuhi Māmā

He pai aua kuputipu barbed mō ngā raina drip pēpi iharanui (<15 PSI), ka tāroihia te taraweti hei here i te tūpuhi māmā. He pai ake ngā kuputipu compression mō ngā pūnaha pēpi waenga (15–50 PSI), ka whakamahia he herema rāpaki e pakari ake ana i te wā o te whakauru. I raro i te parikara karawhiti, ko ngā tauira compression e pupuri ana i te 92% o te anga rere, i te 78% pea i ngā momo barbed i ngā whakamātautau mara.

Ngā Kuputipu Pīrau mō ngā Tūpuhi Puma: Ngā Paerewa NPT ki te BSP

I ngā pūnaha pēpi teitei (>50 PSI), ka aukati ngā kuputipu pīrau i ngā putanga. Whakamahia ngā taonga pīrau National Pipe Thread (NPT) i Ōhinu Amerika ki te Raki, ā, ko British Standard Pipe (BSP) ngā pīrau anuanu kei te ao. Ko te pīrau kore e hāngai ana i ēnei paerewa ka heke te kaha o te hononga umanga 40%, nō reira me tirotiro tonu i te pīrau ki te takotoranga ki mua i te huinga.

Te Whiriwhiri i ngā Kupenga e Ū Ana ki ngā Mātai PVC, Polyethylene, i ngā Mātai Rino rānei

He nui te take o te whiriwhiri i te matā o te kupenga e ū ana ki ngā mātai rereke mō ngā mātai pīpī, ina hiahia ana kia roa te ora me te āki ai i ngā wāhi urutomo. Me whiriwhiri kupenga mō ngā mātai PVC e neke haere ana me te tūpono ōrite ki te mātai, arā pea 0.065 mm ia mita ia celsius mō ngā mātai Schedule 40. Ka āki tēnei i ngā hononga kia kaua e pakaru ina hurihuri ngā wera. Ina mahi ana ki ngā pūnaha polyethylene, ko ngā kupenga parirau maroke kei te pai ake nā te mea e taea eia te neke haere kia kaua ai e pakaru. Me mahara anō kia iti ake i te 2.5 karaka ia meneti te tere o te rere mēnā he tūhura whakapua kaipuke ana. Mō ngā mātai rino pērā i te steel galvanized, me whakamahi kupenga mātai paraurareka e whai ana i ngā āhuatanga dielectric isolation. Āki ēnei i te korairi galvanic e hua ana pea i te 37% o ngā urutomo kimikime mā te pūnaha mātai rino e ai ki tētahi rangahau i tāngia e ngā Inihini Ahuwhenua i te 2022.

Kupenga Paraihe ki te Kupenga Kōwaro i ngā Pūnaha Whakapau Pēhi Teitei: Whakarāpopototanga Whakatairanga

Ko ngā kōpua pātatai he kingi tonu i te nuinga o ngā kāinga, e hāngai ana i te 72% o ngā mea e whakauruhia ana e ngā tāngata āhua inaianei e ai ki ngā raraunga o te Irrigation Association mai i te tau ki muri. Engari, ina heke te pēhi, ka ata marie te pārira ina piki ake te pēhi i te 80 psi. I whakaatu ngā whakamātautau ko ngā wāhanga niponi ka timata te kīkī haere i te 18 ngā wā i runga i te 100 ki te 100 psi i muri i te 500 ngā wā. Ko te pārira ia, ka mau tonu hoki ki ngā pēhi 150 psi mō ngā wā roa. Heoi anō, kei te utu te pārira pea i te 30 ki te 40 miriona atu i ngā kōwhiringa, ā, me te pāpānga motuhake i ia wā e hono ana ki ētahi atu momo metara. Ki te titiro ki ngā take whai mōhio mō ngā pēhi e piki ake i te 100 psi, e tohe ana ētahi tohunga inaianei i ngā kōpua ABS e pupū ana i te UV me ngā toto whenua inarāri. Ka mau tonu ēnei rautaki takirua i te āhuatanga tāpiripiri moni o te pātatai, ā, ka tapiri anō i te kaha atu e kitea ana i ngā wāhanga metara.

Te Pānga o te Kounga Wai me ngā Mea Kaihimataki ki te Momohanga o te Matū Kōpua

Ko te āhua o te wai e hāngai ana ki te roa o te ora o te kōpiko. Ko te wai pūrere whakangarungaru (pH <6.5) e ngaro ana i te karaka ki te 0.12mm/tau, ā, ko ngā rautaki keemikara e piki ake ai te wehe haepapa o te PVC mā te 27% (Te Pokapū Rangahau Mārauāwhiota Kīrehe 2022). Hei whakaiti i te marere:

1. Whakamahia ngā kōpiko tohua NSF-61 ki ngā punaha wai inu
2. Whakaurua ngā taputapu ētihana EPDM ki ngā aronga keemikara takitahi
3. Tāwhai ngā tātari anōtae korokoro ki ngā wāhi hono kōpiko metara

I ngā punaha wai whakamahia anō, ko ngā kōpiko polyethylene kua huinga (PEX) me te taumaha anōipiranti neke atu i te 50% ka ora pea ki te 14 tau—ka toru hoki te rua tekau mā waru tau o te PVC tikanga i raro i te pānga keemikara tonu.

Te Tātai i te Toimaha, Te Manawaroa UV, me te Manawaroa Taiao

Me pēhea te Pānga o te Toimaha Auau ki te Whiriwhiri me te Roa Ora o te Kōpiko

Me manawatia e ngā kōpae ngā pēhanga whakahaere tonu me ngā pikinga poto. Ko ngā momo paraihe ka tēkau mā toru ūruatia ake te nuinga o te wā i te karaka i raro i te huringa kirikiri neke atu i te 60 PSI (Irrigation Materials Journal 2023). Kua whiriwhiria katoa ngā kōpae kua rītenga noa mō te iti rawa 1.5 ngā wā te pēhanga mauiui o te pūnaha hei whakauru mō ngā piki ake i te wā o te tiimata o te hipi.

Te Manawaroa UV i ngā Tāutuhinga Takotoranga: Te Whakāro Arataki i te Ora Moemoeā o ngā Kōpae Paraihe

Ka marere ngā kōpae polypropylene kāore i te ārai UV 40% tere ake i ngā putanga ārai UV, ā, ka hanga pakuwhā ki te mata i roto i ngā tau 3–5 ki ngā rohe hauptopu. Mō te whakamahi takotoranga pūmau, kōwhiria ngā kōpae kei te ngota-kārāhihe, i te taonga ārai UV, i te kiriaki acrylic rānei e whakaputa ana i te 98% o te raipōta UV, ka roa ake te ora ki te tekau tau.

Ngā Whakaaro mō ngā Tāutuhinga Roto, Takotoranga, me Rarowhenua

Raraunga Tārua mō ngā Raraunga Herenga i raro i ngā Kaha Taiao

I tāhuhia e tētahi rangahau pūtaiao ahuwhenua 2022 12,000 herenga:

• i te wāhi e 62% o ngā herenga i te wāhi e mārama ana te ao mārama i ngā herenga paraihe e whakaaetia ana mō te whakamahi ki roto
• Ko ngā herenga mātātoko takutai i te whenua i mau ai te 89% pono i muri i te 8 tau i te upoko o te 54% mō ngā momo kore-papa
• I te pūnaha e pā ana ngā pōkai toto hokiria i ia rā e neke ake i te 25 PSI i te tokorua pea ngā wā e toru noa ngā herenga herenga i te upoko o ngā tautuhinga toto tūmau

Rārangi Mōhio Mō te Whiriwhiri Herenga Me Te Kotahi Kotahi o te Pūnaha

Rārangi tirohanga whānui mō te whiriwhiri i te kowhiringa tika mā te matū, rahinga, me te momo pūnaha

Mua i te whakauru, whakapūmau:

• Te Honoa o ngā Mea me ngā wīra e wātea ana (PVC, LDPE, nēhi rānei)
• Wīra tātou huiarangi tūwai (ine, kāore i te ingoa)
• Te tikanga hononga e hiahiatia ana (compression, barbed, or threaded)
• Te reitingi toharite ake o te pūhiko pūhiko (me whai kowhiringa kākāriki ake i te 100 PSI)
• Te marino ki te ao mārama mō te noho ki waho i te whenua

Whakauruhia ēnei paerewa ki tō arataki waima – e hiahiatia ana ngā pāpā herehere kore-ruarua mō ngā pūnaha drip, kei te pūnaha pivot ka tāroihia ngā kowhiringa pēra hāngai mō te roa haere.

Ngā tātaitanga pūhiko waima me te tere inu mō te mahi tūturu o te kowhiringa

Ko ngā kawhe PVC noa ka pakaru ki tētahi wāhi e 120 ki te 150 pauna ia hā inaia, engari ko ngā kawhe pūrua kaweinea ka taea te tino ake i te 200 PSI. Ina whai koe ana ki ngā tere rere e pānui ake ana i te 15 karaka ia miniti, he mea whai hua kē atu te whiriwhiri i ngā kawhe whānui nō te iti ake o te pouri me te pupuri pai ake i te pēhanga i roto i te punaha. I tētahi rangahau hou a te tau i mua, i kitea ko te kotahi tuatoru o ngā raru rere katoa i ngā takotoranga tohutohu i āhua pea e ngā kawhe e kore nei e tika mō te mahi. Mā mua i te whakauru i tētahi punaha ki te whakamahinga pono, he tikanga ataahua kia whakamahia ngā whakamātau pēhanga e 50% ake nei i te matapae noa. Ka hoatu tēnei he horokiko haumaru, ā, ka āwhina hoki ki te kimihia ngā raru e taea ana i te tīmatanga.
