Me pēhea te ārai i te piri o te aho wiri (te ngaronga o te taumaha ki te mata) i te wā e keri ana?

Ko te kupu "taumaha ngaro i runga i te mata" (LWB) e pā ana ki tētahi āhuatanga i te wā e keri ana, ina kore te taumaha kua hoahoatia i runga i te mata (WOB) e pā ki te mata keri. Engari, nā te nui o te waku i waenga i te aho keri o raro me te pakitara o te poka, ka mimitihia te taumaha katoa e te aho keri.

I te whakamahinga o te WOB, ka pā te whakahekenga o te poka ki te taumaha katoa.aho wiringā mea whakaū rānei. Me whakamahi tonu i te taumaha, engari me whai whakaaro ki te kaha pēhi o te aho wiri. Tērā pea ka puta he nekehanga iti ki raro o te aho wiri i ia pikinga taumaha; mā te whakamahi anō i te taumaha ka taea e te aho wiri te neke atu i te wāhanga poka kua whakapotohia. I te wā e puta atu ai te aho wiri i tēnei wāhanga, ka tere te pa o te mata wiri ki te raro o te poka. Nā te mea he teitei ake te WOB i tēnei wāhi i tērā mō te wiri noa, ka hohonu ake te uru o te mata wiri ki te hanganga, ka piki ake te taipana ohorere. Tērā pea ka mutu te tēpu hurihuri, te puku o runga rānei. Mēnā ka mutu te mahi, kaua e hiki wawetia te aho wiri—tukuna te taipana i te tuatahi. Ka taea te tīmata anō te wiri noa i muri i ngā whakatikatikanga maha.

Ko te ngaronga o te taumaha i runga i te matawai ka puta i ngā wā e whai ake nei: te keri ahunga o ngā puna poutū me te whakamuri-rimu, ngā puna ahunga rānei me ngā mahi whakamuri-rimu maha, te keri ahunga mira matapihi me te huri taha, me te keri ahunga puna whakapae. Nā te ara o te poka me ngā āhuatanga ātete maha, he uaua ki te tuku i te pēhanga e pā ana ki te aho keri ki te matawai. Mai i ngā taputapu tuhi paru whānui me ngā tohu taumaha, ka whakaaturia tēnei penei: kāore te tūranga o te matawai e rerekē ana, ā, kāore he pikitia e whiwhihia ahakoa te pikinga tonu o te WOB; kāore te pēhanga papu e piki ake, ā, kāore he aukati papu e puta. Heoi, ko te pikinga ake o te WOB ka arahi pea ki te aukati ohorere o te papu. Mō ngā puna ahunga, ko te ngaronga o te taumaha i runga i te matawai ehara i te mea ka whakararuraru noa i ngā mahi ahunga noa engari ka tūpono hoki te piri o te paipa mena ka hē ngā mahi.

1.Whakapakari i te Mana Ara o te Puna me te Arotau i te Whirihoranga Aho Wiri

Hei whakatika i te ngaronga o te taumaha i runga i te mata i puta mai i te ara kino o te poka wai, ko te mahi matua a te miihini ko te whakarei ake i te whakahaere ara. Mō ngā poka koki teitei me ngā poka toronga whānui, me whakamahi te whakahaere ārahi-puna katoa kia mau tonu te rerekētanga me te azimuth o te poka kia rite ki te hoahoa, kia kore ai e hoki whakamuri nā te mea he rerekētanga mai i te hoahoa.

Mō te ngaronga o te taumaha i runga i te mata o te poka i puta mai i te ara kino o te poka wai, ko te otinga tino whai hua ko te whakangawari i te whirihoranga o te aho wiri: whakaitihia te maha o ngā kara wiri me te whakanui ake i te maha o ngā paipa wiri taumaha (HWDP). Ka whakaitihia te pakari o te aho wiri, ka whakaitihia te horahanga pa i waenga i te aho wiri me te keke paru, ā, ka ārai i te ngaronga o te taumaha i runga i te mata me te piri rerekētanga.

Mō te whakaiti i te taumaha o te mata poka i roto i ngā poka whakapae, me arotahi ngā mahi ki te horoinga o te poka, te whakahinuhinu, me ngā tikanga whakahaere a te kai keri.

2. Whakapai ake i te Horoi

Ko te whakarei ake i te horoinga ko te horoi i te poka wai me te purenga o te paru mata ma te whakamahi i ngā taputapu whakahaere totoka mata.

Whakapai ake i te kaha o te paru ki te kawe i ngā tapahi

I ngā kaupapa keri ahunga tata nei, e whakamahia whānuitia ana ngā mata PDC me te hangarau mōtini urungi, e tere ai te hora me te huri i ngā tapahi kia angiangi—he uaua tēnei ki te horoi i te poka.

Ngā Whakaritenga Nekehanga mō ngā Wāhanga Puna Rerekē:Mō te wāhanga poka φ311 mm, me teitei ake te nekehanga i te 3.4 m³/min; mō te wāhanga poka φ216 mm, me teitei ake i te 1.1 m³/min.

Whakatikatika i ngā Tawhā Rheological Paru i runga i te Hokinga mai o ngā Tapahi o raro:Mō te wai keri pūmua totoka-iti, me whakahaere te ōwehenga kirihou hihiri i waenga i te 0.42 me te 0.50 kia pai ai te pānga kawe-tapahanga. Mō te matotoru o te paru me te kaha o te tiēre, me pupuri te matotoru o ngā puna ahunga-teitei ki runga ake i te 48 hēkona—mā te matotoru teitei me te kaha o te tiēre ka āwhina i te aukati i te taunga poutū o ngā tapahanga.

I tētahi kaupapa keri, i te wā i 50–60 nekehanga te rerekētanga o te poka, nā te tāpiri o te tiēre pai waro i whakaiti i te matotoru o te paru ki te 42 hēkona pea, ā, ka hua ake he hokinga kino o ngā tapahi ki raro i te poka, ā, ka ngaro te taumaha i runga i te mata i te wā keri ahunga. I whakahokia mai ngā āhuatanga noa o raro i te poka i muri i te whakanui ake i te matotoru o te paru ki te 50 hēkona.

Mō ngā puna he hohonu ake i te 200–300 mita, ka taea te kukume i ngā puna whakapae ki te wāhanga puna me te rerekētanga o te 20–30 nekehanga. I roto i te whirihoranga aho keri mō te keri ahunga, he maha ngā tūnga o ngā kara keri e whakaurua ana. I roto i ngā poka puna hou kua keria, ko te noho mai o ngā kara keri ka whakanui ake i te tere hokinga mai o te paru porowhita, nō reira ka tau ngā moenga tapahi ki roto i te poka puna tawhito. Nō reira, ko ētahi o ngā kapa keri ka kukume noa i te wāhanga puna hou kua keria, he iti noa te pānga ki te wawahi i ngā moenga tapahi.

3. Whakapai ake i te Hinu o te Paru me te Kounga o te Keke Paru

Whakarei ake i te hinu paru

Ko ētahi mahi motuhake hei whakapai ake i te hinu o te paru ko te tuatahi, te whakanui ake i te horopeta o ngā hinu whakahinuhinu, ā, tuarua, te whakamahi i te huinga o ngā momo hinu whakahinuhinu rerekē.

I roto i te keri anga, ka whakaranua te hinu mata ki roto i te paru i ngā mahi anga. Ahakoa he pai te hinu mata, ka heke te kounga o te keke paru i tōna tāpiritanga. Nō reira, i roto i ngā mahi keri anga, me whakamahi te hinu mata me ngā hinu whakahinuhinu wai. Ehara i te mea ka whakatau noa i te raruraru whakahinuhinu engari ka karohia hoki ngā keke paru matotoru i puta mai i te nui rawa o te hinu mata.

Ka piki ake te waku pahekeheke me te tauwehenga waku. Hei whakatika i tēnei, tata ki te 3–5 tana o te hinu mata ka taea te whakaranu ki roto i te paru, me te kore e neke ake i te 9–10% te nui o te hinu mata.

Whakapai ake i te Kounga o te Keke Paru

Hei whakapai ake i te kounga o te keke paru, ka taea te tāpiri i ngā rauemi paru pēnei i te uku whanariki me te kapia phenolic. Ka whakaitihia e te keke paru kounga teitei te mōrearea o te piri rerekētanga i puta mai i te ngaronga o te taumaha ki te mata.

Haunga ngā hinu whakahinuhinu wai, he whai hua anō hoki ngā hinu whakahinuhinu totoka me ngā hinu whakahinuhinu pēhanga nui ki te whakaiti i te taumaha kua ngaro i runga i te mata. Ina ngaro te taumaha i runga i te mata i te wā e keri ana i ngā hanganga mārō, ko te tāpiri i te 200–300 kg o te karāwhata kua whakawhanuitia i te wā kotahi he pānga pai ki te whakakore i te taumaha kua ngaro i runga i te mata i puta mai i te ngoikore o te whakahinuhinu.
