I te wiki i mua atu, i whakaurua e mātou te tukanga takai o ngā pūnga kiriata, ā, i tēnei wiki ka hiahia ahau ki te kōrero mō te hangarau matua o ngā pūnga kiriata.

1. Hangarau whakahaere kumemau tonu

Nā te mea e hiahiatia ana te whai huatanga o te mahi, he teitei ake te takai i te nuinga o te wā i roto i te torutoru maikorona. Ā, he mea tino nui te whakarite kia mau tonu te taumahatanga o te rauemi kiriata i roto i te tukanga takai tere-rahi. I roto i te tukanga hoahoa, ehara i te mea me whakaaro noa tātou ki te tika o te hanganga mīhini, engari me whai pūnaha whakahaere taumahatanga tino pai hoki.

Ko te pūnaha whakahaere he maha ngā wāhanga: te tikanga whakatikatika kume, te pūoko kite kume, te motuka whakatikatika kume, te tikanga whakawhiti, me ētahi atu. Kei te whakaatuhia te hoahoa kauwhata o te pūnaha whakahaere kume i te Pikitia 3.

Me whai pūngao kiriata i tētahi taumata pakari i muri i te takai, ā, ko te tikanga takai wawe ko te whakamahi i te puna hei whakamātao hei whakahaere i te taumahatanga o te takai. Mā tēnei tikanga ka puta he taumahatanga kore taurite ina tere, ka whakaroa, ka mutu te motuka takai i te wā o te takai, ka ngāwari ai te whakararuraru, te whakapē rānei i te pūngao, ā, he nui hoki te ngaronga o te pūngao. I roto i te tukanga takai, me pupuri tētahi taumahatanga, ā, ko te tauira e whai ake nei.

F=K×B×H

I roto i tēnei tātai:F-Tesion

             K-Tauwehenga werohanga

             B-Whānui kiriata (mm)

            H-Te matotoru o te kiriata (μm)

Hei tauira, ko te kukū o te whānui o te kiriata = 9 mm me te matotoru o te kiriata = 4.8μm. Ko tōna kukū ko :1.2×9×4.8=0.5(N)

Mai i te whārite (1), ka taea te whakaputa i te whānuitanga o te kume. Ko te puna porotaka me te pai o te raina ka tīpakohia hei tautuhinga kume, ko te potentiometer aukume kore-pa ka whakamahia hei kimi urupare kume hei whakahaere i te taipana putanga me te ahunga o te motuka servo DC wetewete i te wā e takai ana te motuka, kia mau tonu ai te kume puta noa i te tukanga takai.

2. Hangarau whakahaere takai

 He hononga tata te kaha o ngā matua pūnga ki te maha o ngā takai o te takai, nō reira ko te whakahaere tika i ngā matua pūnga he hangarau matua. Ko te takai o te matua pūnga ka mahia i te tere teitei. Nā te mea ka pā tika te maha o ngā takai takai ki te uara kaha, me tino tika te whakahaere i te maha o ngā takai takai me te tatau, ka tutukihia mā te whakamahi i tētahi waeine tatau tere-teitei, i tētahi pūoko rānei he tino tika te kite. Hei tāpiri, nā te mea me iti te rerekētanga o te kukū rauemi i te wā e takai ana (ki te kore ka wiri te rauemi, ka pā ki te tika o te kaha), me whakamahi te takai i tētahi hangarau whakahaere whai hua.

Ko te whakahaere tere wehewehe me te whakaterenga/whakaroa whaitake me te tukatuka tere rerekē tētahi o ngā tikanga whai hua: ka whakamahia ngā tere takai rerekē mō ngā wā takai rerekē; i roto i te wā tere rerekē, ka whakamahia te whakaterenga me te whakaroa me ngā ānau tere rerekē whaitake hei whakakore i te wiri, me ētahi atu.

3. Hangarau Whakakore Whakarewa

 He maha ngā paparanga rauemi e takaihia ana tetahi ki runga i tetahi, ā, me whakamahana te hiri i te taha o waho me te taha. Me te kore e whakanui ake i te rauemi kiriata kirihou, ka whakamahia te kiriata whakarewa o nāianei, ā, ka whakamahia tōna kiriata whakarewa, ā, ka tangohia tōna whakakikoruatanga whakarewa mā te tikanga tango-whakarewa hei whiwhi i te kiriata kirihou i mua i te hiri o waho.

Ka taea e tēnei hangarau te penapena i ngā utu rauemi, ā, i te wā kotahi ka whakaiti i te diameter o waho o te matua pūnga (mēnā he ōrite te kaha o te matua). Hei tāpiri, mā te whakamahi i te hangarau tango-whakarewa, ka taea te tango i te paninga whakarewa o tētahi paparanga (e rua rānei ngā paparanga) o te kiriata whakarewa i mua i te atanga matua, ā, ka karohia te pakaru o te ara iahiko poto, ka taea ai te whakapai ake i te hua o ngā matua koiri. Mai i te Pikitia 5, ka taea te whakatau kia tutuki ai te pānga tango ōrite. Kua hangaia te ngaohiko tango kia taea te whakarerekē mai i te 0V ki te 35V. Me whakaiti te tere ki waenga i te 200r/min me te 800r/min mō te tango-whakarewa i muri i te takai tere teitei. Ka taea te whakatakoto i ngā ngaohiko me te tere rerekē mō ngā hua rerekē.

4. Hangarau hiri wera

 Ko te hiri wera tētahi o ngā hangarau matua e pā ana ki te tohu o ngā matua pūnga iahiko kua takaihia. Ko te hiri wera ko te whakamahi i te rino whakapiri pāmahana teitei hei whakapiko me te here i te kiriata kirihou i te atanga o te matua pūnga iahiko kua kopikohia e whakaaturia ana i te Pikitia 6. Kia kore ai e pōkarekare te pōkarekare, me here pono, me papatahi hoki te mata o te pito, kia ātaahua hoki. Ko ētahi o ngā mea matua e pā ana ki te pānga hiri wera ko te pāmahana, te wā hiri wera, te hurihanga me te tere o te matua, me ētahi atu.

I te nuinga o te wā, ka rerekē te pāmahana o te hiri wera i runga i te matotoru o te kiriata me te rauemi. Mena he 3μm te matotoru o te kiriata o taua rauemi, ko te pāmahana o te hiri wera kei roto i te awhe o te 280℃ me te 350℃, ko te matotoru o te kiriata he 5.4μm, me whakarite te pāmahana o te hiri wera ki te awhe o te 300cc me te 380cc. Ko te hohonu o te hiri wera e pā tika ana ki te wā hiri wera, te nekehanga kume, te pāmahana rino whakapiri, me ētahi atu. He mea nui hoki te matatau ki te hohonu o te hiri wera mō te hanga i ngā matua pūnga whaimana.

5. Whakamutunga

 Nā te rangahau me te whanaketanga i ngā tau tata nei, he maha ngā kaihanga taputapu o te whare kua whakawhanake i ngā taputapu takai pūnga kiriata. He pai ake te nuinga o ēnei i ngā hua ōrite i te kāinga me tāwāhi i runga i te matotoru o ngā rauemi, te tere takai, te mahi tango-whakarewa me te whānuitanga o ngā hua takai, ā, he taumata hangarau matatau ā-ao. Anei tētahi whakamārama poto noa iho mō ngā hangarau matua o ngā hangarau takai pūnga kiriata, ā, ko tā mātou e tumanako nei, mā te haere tonu o te hangarau e pā ana ki te tukanga hanga pūnga kiriata o te whare, ka taea e mātou te akiaki i te whanaketanga kaha o te umanga taputapu hanga pūnga kiriata i Haina.
