Me pēhea te whakaoti i te raruraru o te pakaru o te pereti matotoru me te toenga e pā ana ki te tapahi

Ina tapahia ngā pereti matotoru mā te whakamahi i te rēseri, ka pā te toenga (para) i puta mai i te poka ki te kounga o te tapahi, he raruraru noa engari ka taea te whakapai ake. Ko te nuinga o te wā ka puta mai ēnei toenga i te whakahaere pūngao hē i te wā o te tukanga poka, te kore taurite o ngā tawhā hau, ngā tawhā tukanga koretake rānei. Ko ngā otinga pūnaha me ngā taunakitanga whakapai ake e whai ake nei:

te arotautanga o te tukanga poka

1. Te whakamahi i te poka whakapūmau (pokamau paparanga)

• Mō ngā pereti matotoru (hei tauira, > 15mm), karohia te whakamahi i te poka mana tihi teitei kotahi, ā, whakamahia te pikinga mana taahiraa, te poka wāhanga rānei hei uru mārire ki roto i te rauemi, hei whakaiti hoki i te tauhiuhi o te paru.
• Tikanga whakahaere: Whakatakotoria te tawhā "wāhanga wehewehe" i roto i te pūmanawa tapahi, whakamahanahia tuatahi me te mana iti iho, kātahi ka whakanuia haeretia te mana hei wero.

2. Whakatikatikahia ngā tawhā poka

• Whakaitihia te kaha tino kaha, ā, whakaroahia te wā poka:whakaiti i te tauhiuhi o ngā rauemi rewa i puta mai i ngā pahūtanga pūngao ohorere.
• Whakanuia te auau poka (huringa mahi):Whakahaerehia te tere o te putanga o te pūngao o te pā o te taiaho hei karo i te rewa nui.
• Tauira tohutoro tawhā (mā te whakamahi i te maitai waro 20mm hei tauira):
• Mana: 1000-1500W (ka whakarerekētia kia rite ki te kaha o te taputapu)
• Te wā poka: 1.5-3 hēkona
• Auautanga pātere: 200-500Hz
• Te pēhanga hau āwhina: te whakatikatika ā-wāhanga (tirohia i raro)

Mana whakahaere hau āwhina

1. Te arotautanga o te momo hau me te pēhanga

• Waro maitai: Ka whakamahia te hāora (O₂) hei hau āwhina, engari me whakahaere te pēhanga. I te wāhanga poka, ka taea te whakamahi i te pēhanga iti (0.5-1bar) i te tuatahi, kātahi ka taea te huri i te pēhanga tapahi ki te pēhanga teitei (1.5-2.5bar) i muri i te werohanga hei karo i te tauhohenga nui o te hāora ki te whakaputa i te nui o te para.
• Rino kowiri tira/rino koranu: whakamahia te hauota (N₂) te hau rānei, whakamahia te pēhanga reo me te pēhanga iti (6-10bar) mō te poka, ā, huri ki te tapahi hauota parakore-teitei pēhanga teitei i muri i te pokanga.

2. Te whakaroa o te hau me te kati wawe

• Whakawhitihia te hau i mua i te otinga o te poka: whakawhiti ki ngā tawhā hau mō te tapahi ina tata te otinga o te poka hei āwhina i te pupuhi atu i te paru i roto i te kōhao.
• Whakanuia te wā pupuhi i mua i te hau: pupuhihia mō te 0.5-1 hēkona i mua i te poka hei horoi i te wāhi poka, hei whakamatao hoki i te rauemi e karapoti ana.

Tūnga Arotahi me te Whakaritenga o te Pūwero

1. Tūnga arotahi

• I te wā e pokaia ana, whakamahia he nui o te whakakorenga arotahi (kei raro i te mata o te pereti te arotahi) hei whakanui ake i te whakatuwheratanga me te whakahaere i te tukunga paru. Hei tauira, ka taea e te maitai waro 20mm te whakatakoto i te pūwāhi arotahi 3-5mm i raro i te mata.
• I muri i te werohanga, whakarerekētia te arotahi ki te tūranga pai rawa atu kia rite ki ngā whakaritenga tapahi.

2. Te kōwhiringa me te teitei o te pūwero

• Whakamahia ngā pūwero he whānui ake (pēnei i te φ2.0-φ3.0mm) hei whakanui ake i te kapi o te hau me te whakatairanga i te tukunga o te paru.
• Me whakarite kia ōrite te teitei o te pūwero (1.0-2.0mm te nuinga) kia kore ai e horapa te hau i te mea he tiketike rawa, me te kino o te pupuhi i te mea he iti rawa.

Ara tukanga me ngā pūkenga hōtaka

1. Kōhao mata kua keria i mua

• Mō ngā pereti matotoru rawa (hei tauira, > 30mm), ka taea te keri ā-ringa i ngā kōhao iti te whānui i te tuatahi, kātahi ka taea te tīmata te tapahi i te taiaho mai i ngā kōhao hei karo i te poka tika.

2. Whakatakotoria te tauwehenga pūwāhi poka

• I te wā e whakarite ana i te kaupapa, me wehe te pūwāhi poka mai i te rārangi āhua tūturu mā te 1-2mm, kātahi ka neke mai i te pūwāhi taupatupatu ki te rārangi āhua i te wā e tapahi ana kia kore ai e kohia te toenga.

3. Te tapahi i te arotautanga ara

• Ka whakamahia ngā poka porowhita, ngā wāhi tīmatanga tapahi porowhita rānei hei hora i te para ki te wāhi kāore i tapahia.

Arotakenga taputapu me te tiaki

1. Āhua o te taiaho

• Tirohia mēnā he pumau te mana whakaputa, kia ma te karu arotahi/whakaata tiaki, ā, kia kore e ranea ngā poka i puta mai i te ngoikore o te pūngao.

2. Te parakore me te rere o te hau

• Me whakarite kia parakore te hau (ina koa te hauota/hāora), ā, tirohia tonutia mēnā kei te āraia, kei te turuturu rānei te ara hau.

3. Kua whakaritea te pūwero ki te wāhanga whatu.

• Whakatikatikahia te kokonga o te pūwero me te hihi taiaho i ia wā kia ōrite ai te rere o te hau.

Ngā Rauemi me ngā Āhuatanga Taiao

1. Te maimoatanga mata o te pereti

• Horoia te paparanga waikura, te paru hinu, te paninga rānei i runga i te mata o te pereti i mua i te tapahi hei whakaiti i te whai wāhi o ngā poke ki te tauhohenga.

2. Te papatahi o te pereti

• Me whakarite kia papatahi te pereti, kia kore ai e puta he āputa e turuturu ai te hau me te whakaata i te pūngao.

Te taunakitanga mō te tukanga patuiro tawhā

1. Tuatahi, whakatikahia ētahi atu tawhā, āta whakatikatikahia te wā me te kaha o te poka, tirohia te nui o te paru i hangaia, ka kimihia te pūwāhi taurite.

2. Tuhia ngā tawhā arotau, ā, whakatūria te pātengi raraunga tukanga o ngā rauemi/matotoru rerekē.

3. Whakamātautau me te manatoko: he maha ngā whakamātautau poka e whakahaerehia ana ki te para hei whakaū kua whakaitihia te paru i mua i te tapahi ōkawa.

Whakarāpopototanga: Tirotiro Tere i ngā Kaupapa Matua

Mā te whakatikatika whānui i runga ake nei, ka taea te whakaiti i te toenga matotoru o te pereti pakaru, ā, ka taea te whakapai ake i te kounga me te whai huatanga o te tapahi. Mena ka mau tonu te raruraru, me whakapā atu ki te kaihanga taputapu mō te whakamātautau taputapu, te tautoko tukanga rānei.
