8 ngā āhuatanga o te wiri hurihuri me āna mahi

E mōhio ana koe ki ēnei kupu: Koki tōrino, koki pūwāhi, mata tapahi matua, kōtaha o te putorino? Ki te kore, me haere tonu koe ki te pānui. Ka whakautua e mātou ngā pātai pēnei i: He aha te mata tapahi tuarua? He aha te koki tōrino? He aha te pānga ki te whakamahinga i roto i tētahi tono?

He aha te mea nui kia mōhio ki ēnei mea: He rerekē ngā whakaritenga mō te taputapu e whakamahia ana e ngā rauemi rerekē. Nā reira, he mea tino nui te whiriwhiri i te wiri hurihuri me te hanganga tika mō te hua o te keri.

Me titiro tātou ki ngā āhuatanga matua e waru o te wiri hurihuri: Koki ira, mata tapahi matua, mata whao tapahi, mata tapahi ira me te mata angiangi, te kōtaha o te putorino, te uho, te mata tapahi tuarua, me te koki porowhita.

Hei whakatutuki i te mahi tapahi tino pai i roto i ngā rauemi rerekē, me taurite ngā āhuatanga e waru tetahi ki tetahi.

Hei whakaatu i ēnei, ka whakatauritea e mātou ngā wiri hurihuri e toru e whai ake nei:

• Wiri hurihuri DIN 338, HSS-E
• Ngā wiri miro DIN 338, HSSE-Co M35
• Wiri hurihuri DIN 338, HSS 4341

Koki pūwāhi

Kei te pane o te wiri hurihuri te koki pūwāhi. Ka inehia te koki i waenganui i ngā taha tapahi matua e rua i te tihi. Me whai koki pūwāhi kia uru ai te wiri hurihuri ki roto i te rauemi.

Ka iti ake te koki o te ira, ka māmā ake te whakapū i te rauemi. Ka whakaitihia hoki te tūponotanga o te paheke i runga i ngā mata piko.

Ka nui ake te koki o te pūwāhi, ka poto ake te wā pato. Heoi, me nui ake te pēhanga pa, ā, he uaua ake te whakanoho ki waenganui o te rauemi.

Ki te whakaritea te āhuahanga, ko te koki pūwāhi iti he roa ngā tapa tapahi matua, ko te koki pūwāhi nui ia he poto ngā tapa tapahi matua.

Ngā tapa tapahi matua

Ko ngā taha tapahi matua te kaiwhakahaere o te mahi keri. He nui ake te kaha o ngā taha tapahi roa i ngā taha tapahi poto, ahakoa he iti noa ngā rerekētanga.

E rua ngā mata tapahi matua o te wiri hurihuri e honoa ana e te mata whao kua tapahia.

Tapahia te mata o te whao

Kei waenganui o te pito o te wiri te mata o te whao kua tapahia, ā, kāore he pānga tapahi. Heoi, he mea nui mō te hanganga o te wiri hurihuri, nā te mea ka hono i ngā mata tapahi matua e rua.

Ko te mata o te whao kua tapahia te kawenga mō te tomo ki roto i te rauemi, ā, ka pēhia, ka wakuhia hoki te rauemi. Ko ēnei āhuatanga, kāore e pai mō te tukanga keri, ka hua ake te pikinga o te whakaputa wera me te pikinga o te whakapaunga hiko.

Heoi, ka taea te whakaiti i ēnei āhuatanga mā te mea e kiia nei ko te "whakaiti".

Ngā tapahi pūwāhi me ngā whakaangawari pūwāhi

Mā te angiangi o te pito ka whakaitihia te mata o te whao i tapahia i te tihi o te wiri miro. Mā te angiangi ka tino whakaitihia te kaha o te waku i roto i te rauemi, ā, ka whakaitihia hoki te kaha whāngai e tika ana.

Ko te tikanga o tēnei ko te angiangi te mea nui hei whakatau i te pokapū o te rauemi. Ka pai ake te patopato.

Kua whakapūmautia ngā momo whakaangatanga ira i roto i ngā āhua DIN 1412. Ko ngā āhua tino kitea ko te ira porowhita (āhua N) me te ira wehewehe (āhua C).

Kōtaha o te putorino (kōtaha awaawa)

Nā te mea he pūnaha hongere te mahi a te kōtaha o te putorino, ka āwhina i te mimiti me te tango i ngā maramara.

Ka whānui ake te kōtaha o te awaawa, ka pai ake te mimiti me te tango i te maramara.

Ki te kore e pai te tango maramara, ka nui ake te wera e puta mai ana, ā, ka taea e tēnei te whakawerawera, ā, ka mutu, ka whati te wiri hurihuri.

He papatahi ngā kōtaha awaawa whānui, he hōhonu ngā kōtaha awaawa angiangi. Ko te hōhonutanga o te kōtaha awaawa te mea e whakatau ana i te matotoru o te matua keri. Ka taea e ngā kōtaha awaawa papatahi te hanga i ngā diameter matua nui (matotoru). Ka taea e ngā kōtaha awaawa hōhonu te hanga i ngā diameter matua iti (angiangi).

Matua

Ko te matotoru o te matua te mehua mō te pumau o te wiri hurihuri.

He pakari ake ngā wiri miro he nui (matotoru) te whānui o te matua, nō reira he pai mō ngā taipana teitei me ngā rauemi mārō ake. He tino pai hoki mō te whakamahi i roto i ngā wiri ā-ringa nā te mea he ātete ake ki ngā wiri me ngā kaha taha.

Hei whakahaere i te tango i ngā maramara mai i te awaawa, ka piki ake te matotoru o te matua mai i te pito o te wiri ki te kakau.

Ngā porowhita ārahi me ngā tapa tapahi tuarua

Kei ngā putorino ngā poroporo ārahi e rua. Ka mahi anō hoki ngā poroporo koi ki ngā mata taha o te poka wai, ā, ka tautoko i te ārahi a te wiri hurihuri i roto i te poka wai kua keria. Ko te kounga o ngā pakitara poka wai ka whakawhirinaki anō hoki ki ngā āhuatanga o ngā poroporo ārahi.

Ko te mata tapahi tuarua te whakawhiti mai i ngā kōhao ārahi ki te kōtaha awaawa. Ka wetekina, ka tapahia hoki ngā maramara kua piri ki te rauemi.

Ko te roa o ngā porowhita ārahi me ngā tapa tapahi tuarua e whakawhirinaki ana ki te koki porowhita.

Koki porowhita (koki porowhita)

Ko tētahi āhuatanga nui o te wiri hurihuri ko te koki porowhita (te koki porowhita). Mā tēnei ka whakatau i te tukanga o te hanganga maramara.

Mā ngā koki porowhita nui ake ka taea te tango pai i ngā rauemi ngohengohe, roa-marara. Engari, mā ngā koki porowhita iti ake ka whakamahia mō ngā rauemi mārō, poto-marara.

Ko ngā wiri hurihuri he iti rawa te koki porowhita (10° – 19°) he porowhita roa. Hei utu, ko ngā wiri hurihuri he koki porowhita nui (27° – 45°) he porowhita poto (he porowhita). Ko ngā wiri hurihuri he porowhita noa he koki porowhita 19° – 40°.

Ngā mahi a ngā āhuatanga i roto i te tono

I te tirohanga tuatahi, he tino uaua te kaupapa o ngā wiri hurihuri. Ae, he maha ngā wāhanga me ngā āhuatanga e wehewehe ana i te wiri hurihuri. Heoi, he maha ngā āhuatanga e hono tahi ana tetahi ki tetahi.

Hei kimi i te wiri hurihuri tika, ka taea e koe te whakarite i a koe ki tō tono i te taahiraa tuatahi. E whakamārama ana te pukapuka DIN mō ngā wiri me ngā totohu, i raro i te DIN 1836, i te wehenga o ngā rōpū tono kia toru ngā momo N, H, me W:

I ēnei rā, ehara i te mea ko ēnei momo e toru ko N, H, me W anake ka kitea i te mākete, nā te mea i roto i te wā, kua rerekē te whakaritenga o ngā momo hei arotau i ngā wiri hurihuri mō ngā tono motuhake. Nō reira, kua hangaia ngā momo ranu kāore i te paerewahia ngā pūnaha ingoa i roto i te pukapuka DIN. I MSK, ehara i te mea ko te momo N anake ka kitea e koe, engari ko ngā momo UNI, UTL, VA rānei.

Whakamutunga me te whakarāpopototanga

Nā, kua mōhio koe ki ngā āhuatanga o te wiri hurihuri e pā ana ki te tukanga keri. Mā te ripanga e whai ake nei ka hoatu he tirohanga whānui ki a koe mō ngā āhuatanga tino nui o ngā mahi motuhake.

Ko te tikanga, ka taea e koe te whakatau i te momo rauemi e hiahiatia ana me te momo e whakamahia ana.

Tirohia ngā wiri hurihuri e tukuna ana, ka whakatairite i ngā āhuatanga me ngā mahi e hiahiatia ana e koe kia taea ai te keri i tō rauemi.
