He aha te rerekētanga i waenga i ngā peera roera porotaka me ngā peera roera ngira?

 

Ngā peera roera porotaka

Ngā peera roera porotakanō ngā peera tika, ā, ko te arataki flange o te peera pou roera kua whakaritea kia tika he mea hanga mai i te whare herehere, ngā roera me te mowhiti pou ārahi, ka taea te wehe i tētahi atu mowhiti peera, ā, nō tētahi peera ka taea te wehe. He watea ake te tāuta me te wetewete i tēnei momo peera, inā koa ka hiahiatia kia uru ngā mowhiti o roto, o waho, ngā pou me ngā whare ki te pokanoa.

 

Kei te hono atu ēnei peera ki ngā ara rere. He nui te kaha kawenga, ā, ko te nuinga o te wā ka mau i ngā kawenga radial. Ko ngā peera rarangi kotahi anake me ngā flanges i roto i ngā mowhiti o roto me waho ka taea te kawe i te kawenga tuaka iti pumau, i te kawenga tuaka nui rānei; ki te whakataurite ki ētahi atu peera kohikohinga me ngā rahi ōrite, he āhuatanga o tēnei momo peera ko te kawenga nui, te haruru o raro me te tere teitei, ā, he iti te waku i waenga i te huānga hurihuri me te flanges mowhiti, ā, he pai mō te huri tere teitei. He pai mō te whakamahi me ngā momo mīhini tika katoa me ngā mīhini mira hurihuri keri. Heoi, me tino miihini ngā toki, ngā huānga hurihuri me ētahi atu wāhanga e hono ana ki aua peera.

 

E ai ki te mea he flange te mowhiti, ka taea te wehewehe ki ngā peera roera kotahi-rārangi NU, NJ, NUP, N, NF me ētahi atu peera roera porotaka kotahi-rārangi, me ngā peera roera rua-rārangi NNU, NN me ētahi atu. He hanganga wehe te peera me te mowhiti o roto me te mowhiti o waho.

 

Ngā peera roera porotakaKāore he āputa i roto i ngā mowhiti o roto, o waho rānei, ka taea te neke ki te taha tuaka, ā, ka taea te whakamahi hei peera mutunga kore. Ka taea e ngā peera roera porotaka me ngā āputa takirua i tetahi taha o ngā mowhiti o roto, o waho hoki, me te āputa kotahi i tetahi taha o te ferrule te tu atu i tētahi taumata o te kawenga tuaka i te taha kotahi. I te nuinga o te wā, ka whakamahia ngā whare herehere pereti maitai, ngā whare herehere totoka rānei kua hurihia ki te koranu parahi. Heoi, ka hangaia ētahi whare herehere mā te whakamahi i te polyamide.

Ngā peera roera ngira

Ko ngā peera roera ngira he peera roera me ngā roera porotaka, he angiangi, he roa hoki i runga i te whānui. Ka kiia ēnei roera he roera ngira. Ahakoa te iti o ngā wāhanga whakawhiti, he nui te kaha kawenga o ngā peera, ā, he roera angiangi, he roera roa hoki ngā peera roera ngira (te whānui roera D≤5mm, R/D≥2.5, ko L te roa o te roera), nō reira he kiato te hoahoa porowhita, ā, he rite tonu te whānui o roto me te kaha kawenga ki ērā o ētahi atu momo peera, ko te whānui o waho te iti rawa, he mea tino pai mō ngā hanganga tautoko he iti noa ngā rahinga whakairi porowhita.

 

Nō reira, ko ngā peera roera ngira te nuinga o te wā e whakamahia ana i ngā wā he iti te wāhi, nō reira he whānui te whakamahinga i roto i ngā motuka, ngā motopaika, me ngā mīhini kakahu. Ā, he kōwhiringa te mowhiti o roto o te roera ngira, ki te kī tika, ki te tutuki te pakeke me te taratara o te rakau i ngā whakaritenga, kāore e taea te ōrite ki te mowhiti o roto (he iti te wāhi), engari ki te iti te taumata miihini o te rakau, he ngawari rānei, me ōrite te mowhiti o roto hei ara reihi.

 

Ngā rerekētanga i waenganui ingā peera roera porotaka me ngā peera roera ngirakoia ēnei:

 

1. Ko te wāhanga hurihuri o te peera roera porotaka he roera whakarara; ko ngā wāhanga hurihuri o ngā peera roera ngira he roera āhua ngira;

 

2. He nui ake te hanganga o ngā peera roera porotaka i tērā o ngā peera roera ngira;

 

3. Haunga te kaha radial, ka taea hoki e te roera porotaka te tu atu i te kaha axial, ko te peera roera ngira ka taea anake te tu atu i te kaha radial;

 

4. Ka wehea ngā peera roera porotaka ki ngā rarangi kotahi, rarangi rua me rarangi maha, e whakamahia ana ki ngā taiao me ngā huihuinga rerekē;

 

5. He teitei ake te tere mahi o ngā peera roera porotaka i tērā o ngā peera roera ngira;

 

6. Ko ngā peera roera porotaka he mea hanga i te maitai peera kounga teitei me te maitai motuhake; ko ngā peera roera ngira angiangi he mea tā ki ngā pereti maitai. 

 

Āhea te whakamahi

 

I roto i te hoahoa miihini, ko te rahi o te toki te mea tuatahi ka whakatauhia, kātahi ka tīpakohia te peera hurihuri kia rite ki te rahi o te toki. Heoi, ki te whakawhāitihia te ahunga whānui o te peera i te taha o te mīhini, ka tīpakohia ngā peera roera ngira, ngā peera poroporo, ngā peera roera rānei o te raupapa māmā rawa me te raupapa māmā rawa; ki te whakawhāitihia te tūranga tuaka o te peera i roto i te mīhini, ka wātea ngā raupapa whaiti, whaiti rawa rānei o ngā peera poroporo, roera rānei.

 

Ko ngā wāhanga roera ngira me te whare herehere, ngā peera roera ngira mowhiti waho kua tāia, ngā peera roera ngira mowhiti totoka, ngā peera roera ngira pana e whakamahia whānuitia ana i roto i te pūnaha tuku, te pūnaha urungi, te tokotoko hono miihini motopaika o ngā motuka me ngā mīhini hanga, me ētahi atu, ā, he pai mō ngā wā he iti te wāhi me te nui o te kaha kawe. He roera angiangi, he roa hoki ngā peera roera ngira (ko te roa o te roera he 3~10 ngā wā o te whānui, ā, ko te whānui kāore i te neke atu i te 5mm), nō reira he kiato te hanganga radial, ā, ko te rahi o roto me te kaha kawenga he rite ki ērā o ētahi atu momo peera, ā, ko te whānui o waho te mea iti rawa, he tino pai mō ngā hua tautoko ina he iti te rahi o te tāutanga radial.
