Ngā Momo me te Whakarōpūtanga o ngā Peera Porowhita

 

1. Ngā peera porowhitaka whakarōpūtia i runga i te ahunga o te kawenga ka taea e rātou te pikau, i te koki whakapā ingoa rānei:

 

a) Ngā whāriki porowhita — e whakamahia ana hei pikau i ngā kawenga porowhita, me te koki whakapā ingoa o te 0°≤τ≤30°. E ai ki ngā koki whakapā ingoa rerekē, ka taea te wehewehe anō kia:

 

1) Ngā peera porowhita whakapā-ā-torotoro — ngā peera me te koki whakapā ingoa τ=0°. He pai mō te kawe i ngā kawenga ā-torotoro, ā, ka taea hoki te kawe i ngā kawenga tuaka iti i ngā ahunga katoa;

 

2) Ngā peera porowhita torotika whakapā koki— ngā peera me te koki whakapā ingoa 0°<τ≤30°. He pai mō ngā kawenga whakakotahi me ngā wāhanga radial me te axial.

 

b) Ngā peera pana — e whakamahia ana hei pikau i ngā kawenga tuaka, me te koki whakapā ingoa o te 30°<τ≤90°. E ai ki ngā koki whakapā ingoa rerekē, ka taea te wehewehe anō kia:

 

1) Ngā peera porowhita pana whakapā tuaka — ngā peera pana me te koki whakapā ingoa τ=90°. He pai mō te kawe i ngā kawenga tuaka i te ahunga kotahi;

 

2) Ngā peera porowhita pana koki - ngā peera pana me te koki pa ingoa 30°<τ<90°. He pai mō te kawe i ngā kawenga tuaka, engari ka taea hoki te kawe i ngā kawenga whakakotahi.

 

2.Ngā peera porowhitae whakarōpūtia ana i runga i te hanganga o te mowhiti o waho:

 

a) Porowhita porowhita mowhiti waho kotahi-wahi;

 

b) Porowhita porowhita mowhiti waho kotahi-wehenga;

 

c) Porowhita porowhita mowhiti waho wehewehe-rua;

 

d) He mowhiti porowhita porowhita o waho e rua ngā wāhanga.

 

3. Ngā peera porowhitaka whakarōpūtia i runga i te mea e piri ana ki te pito o te tokotoko:

 

a) (Whānui) ngā peera porowhita;

 

b) Ngā peera porowhita pito tokotoko, me ngā tikanga whakarōpūtanga maha:

 

1) E ai ki ngā wāhanga e hono ana ki te pito o te tokotoko:

 

— He whāriki porowhita pito tokotoko kua huihuia: he pito tokotoko he kōhao porotaka, he whāriki porowhita torowhā kua tāuta ki roto i te kōhao, me te pūtu, me te kore rānei;

 

— He whāriki porowhita pito tokotoko kotahi-wahi: he pito tokotoko he poka porowhita o roto, me te mowhiti o roto o te whāriki kua tāuta ki roto i te poka, me te pūtu, me te kore rānei;

 

— Pūtu upoko-pōro, peera porowhita, pito tokotoko: pito tokotoko me te nohoanga pōro, e tāutahia ai he pūtu upoko-pōro.

 

2) E ai ki ngā āhuatanga hononga o te kakau pito tokotoko:

 

— Miro ā-roto o te pito tokotoko porowhita: he tokotoko tika te kakau pito tokotoko me te miro ā-roto;

 

— Miro o waho te pito tokotoko porowhita: he tokotoko tika te kakau pito tokotoko me te miro o waho;

 

— He whāriki porowhita te pito o te tokotoko me te turanga whakarewa: he nohoanga flange te kakau pito o te tokotoko, he nohoanga tapawhā, he nohoanga porotaka rānei me ngā pine tūnga, ka whakamaua ki te pito o te tokotoko mā te whakarewa;

 

— He whāriki porowhita pito tokotoko me te nohoanga raka: he mokowā miro ā-roto tō te pito tokotoko me te taputapu raka.

 

4. Ka whakarōpūtia ngā peera porowhita i runga i te hiahia kia pania anōtia, kia tiakina hoki i te wā e whakamahia ana:

 

a) Ngā peera porowhita kua pania ki te hinu tiaki;

 

b) Ngā peera porowhita whakahinuhinu-ā-ia-anō, kāore e hiahiatia he tiaki.

 

5. Ka whakarōpūtia ngā peera porowhita e ai ki te huinga o ngā rauemi i whakamahia mō ngā mata reti:

 

a) Ngā peera porowhita maitai/maitai;

 

b) Ngā peera porowhita maitai/parahi;

 

c) Ngā peera porowhita hiato maitai/PTFE;

 

d) Ngā peera porowhita o te papanga maitai/PTFE;

 

e) Ngā peera porowhita maitai/kirihou whakapakaritia;

 

f) Ngā peera porowhita he mea hanga ki te maitai/konutea.

 

6. Ka whakarōpūtia ngā peera porowhita kia rite ki ngā waeine e whakamahia ana mō ngā inenga me ngā manawanui:

 

a) Ngā peera porowhita ine;

 

b) Ngā peera porowhita emepaea.

 

7. Kua whakarōpūtia whānuitia ngā peera porowhita e ai ki te ahunga o ngā kawenga, te koki whakapā ingoa, me te momo hanganga:

 

a) Ngā whāriki porowhita torotika;

 

b) Ngā whāriki porowhita whakapā koki;

 

c) Ngā whāriki porowhita pana;

 

d)Ngā peera porowhita o te pito tokotoko.

Ka taea hoki te wehewehe i ngā peera porowhita ki ngā momo hanganga rerekē e ai ki te āhua hanganga (hei tauira, te aroaro, te kore rānei o ngā taputapu hiri, te hanganga o ngā awaawa me ngā kōhao whakahinuhinu, te hanganga o ngā awaawa tohatoha whakahinuhinu, te maha o ngā awaawa mowhiti pupuri, te ahunga hurihuri o ngā miro pito tokotoko, me ētahi atu).
