He maha ngā huarahi noa hei whakarōpū i ngā peera hurihuri

1. Whakarōpūtia kia rite ki te momo hanganga peera hurihuri

Ngā peeraka wehea kia rite ki ngā ahunga kawenga rerekē, ki ngā koki whakapā ingoa rānei ka taea e rātou te pikau:

1) Ngā peera pūtoro---- e whakamahia ana mō ngā peera hurihuri e mau ana i ngā kawenga radial, me ngā koki whakapā ingoa mai i te 0 ki te 45. E ai ki te koki whakapā ingoa, ka wehea kia rua: te peera whakapā radial ---- te peera radial me te koki whakapā ingoa o te 0: te peera whakapā koki radial ---- te peera radial me te koki whakapā ingoa nui atu i te 0 ki te 45.

2)Ngā peera pana---- e whakamahia ana mō ngā peera hurihuri e mau ana i ngā kawenga tuaka, ā, ko ō rātou koki whakapā ingoa he nui ake i te 45 ki te 90. E ai ki ngā koki whakapā ingoa rerekē, ka wehea ēnei ki: ngā peera whakapā tuaka ---- ngā peera pana me ngā koki whakapā ingoa o te 90: ngā peera whakapā koki pana ---- ngā peera pana me ngā koki whakapā ingoa nui ake i te 45 engari iti iho i te 90.

 

E ai ki te momo huānga hurihuri, ka wehea ngā peera kia:

1) Ngā peera pōro---- ngā huānga hurihuri hei pōro:

2) Ngā peera roera---- he roera ngā huānga hurihuri. E ai ki te momo roera, ka wehea ngā peera roera ki:

ngā peera roera porotaka---- he peera roera porotaka ngā huānga hurihuri, ā, ko te ōwehenga o te roa me te diameter o ngā roera porotaka he iti iho i te 3, he ōrite rānei;

Ko te huānga hurihuri o te whīra roera ngira ---- ko te whīra o te roera ngira, ā, ko te ōwehenga o te roa ki te diameter o te roera ngira he nui ake i te 3, engari ko te diameter he iti iho i te 5mm, he ōrite rānei ki te 5mm;

Ngā peera roera whakarara---- ko ngā huānga hurihuri he peera mō ngā roera whaiti; ko ngā peera roera porowhita—ko ngā huānga hurihuri he peera mō ngā roera porowhita.

 

Ngā peeraka wehea kia whai ake nei i runga i te taea te whakarerekē i te wā e mahi ana:

1) Whāriki porowhita---- he porowhita te ara reihi, ka taea te urutau ki te rerekētanga koki me te nekehanga koki i waenga i ngā rārangi tuaka o ngā ara reihi e rua;

2) Ngā peera kore-whakataurite(ngā peera pakari) ---- ngā peera ka taea te ātete i te rerekētanga koki tuaka i waenga i ngā ara reihi.

 

Ngā peeraka wehea kia rite ki te maha o ngā huānga hurihuri:

1) Ngā peera rarangi kotahi---- ngā peera me te rarangi o ngā huānga hurihuri;

2)Ngā peera rarangi-rua---- ngā peera me ngā rarangi e rua o ngā huānga hurihuri;

3)Ngā peera maha-rārangi---- ngā peera me ngā rarangi neke atu i te rua o ngā huānga hurihuri, pērā i ngā peera rarangi-toru me ngā peera rarangi-whā.

 

Ngā peeraka wehea kia rite ki te taea te wehewehe i ō rātou wāhanga:

1) Ngā peera wetewete---- ngā peera me ngā wāhanga ka taea te wehe;

2) Ngā peera kore e taea te wehewehe---- ngā peera e kore e taea te wehe noa i ngā mowhiti i muri i te taurite whakamutunga.

 

Ngā peeraka taea hoki te wehewehe ki ngā momo hanganga maha e ai ki ō rātou āhua hanganga (pēnei i te mea he awaawa whakakī, he mowhiti o roto, o waho me te āhua o te mowhiti, te hanganga o te flange, tae atu ki te mea he whare herehere, me ētahi atu).

 

Te whakarōpūtanga i runga i te rahi o ngā peera hurihuri Ka wehea ngā peera kia rite ki ō rātou diameter o waho:

(1) Ngā peera iti---- ngā peera he iti iho i te 26mm te whānui o waho;

(2) Ngā peera iti---- ngā peera me te diameter o waho ingoa mai i te 28 ki te 55 mm;

(3) Ngā peera iti me te rahi-waenga ---- he peera me te diameter o waho ingoa i roto i te awhe 60-115mm;

(4) Ngā peera waenga me ngā peera nui---- me te whānuitanga rahi o waho o te 120-190mm

(5) Ngā peera nui---- ngā peera me te diameter o waho ingoa mai i te 200 ki te 430mm;

(6) Ngā peera nui rawa atu---- ngā peera me te diameter o waho ingoa mai i te 440mm neke atu rānei
