He aha ngā tohutohu haumaru mō te whakamāhi i ngā pōro tāwhai?

Te whakamārama i ngā whakamātautau o ngā pātaka kōrero me ngā huarahi o te whakawātea

Ngā Take Matua o te Whakawātea o ngā Pātaka Kōrero: Ngā hapa, te whakamāhi, me ngā whakamāhi hē

He toru ngā take matua e tū ana i te whakamāmā o ngā pōkai whakawhitinga: ngā raru mai i te whakamāhunga, ngā hāinga a ngā kaimahi, me ngā whakamātautau hāngā. I ēnei wā, ka puta mai ngā pōkai i te pātaka kē mai i ngā hapa kīato, pērā i ngā rereke o ngā kōpae, i ngā rereke iti o ngā pātā, i ngā kāhore i kitea i ngā whakamātautau kounga. Ka whakamāmā i ngā pōkai ēnei raru i mua tonu i te whakamātautau tuatahi. Ko ngā hāinga a ngā kaimahi hoki e tū ake ana i te ao pūkenga. Inā he iti te whakamātau i te pōkai i te tāwhai, inā he iti te whakamātau i te pōkai i te whakamātautau i te rākau, inā he iti te whakamātau i te pōkai i te whakamātautau i te mea e kaha ana i te whakamātautau, ko ngā wāhi e whakamāmā ai ngā pōkai, ā, ko ngā pātā e whakamāmā ai. Ko te take anō he whakamātautau i te pōkai hāngā mō te mahi. He nui ngā whakamātautau i tēnei wāhi. He tauira, mēnā he pōkai whakawhitinga mātātoko te whakamātautau, ā, he whakamātautau i te porowhita kaha, ka piki ake te hōhi, ā, ka whakamāmā ake te pōkai i tēnei wā. Me titiro kia pai ki te pōkai i mua i te timatanga o te mahi. Me whakamātautau kia tūturu ngā tohu o te pātā, pērā i ngā pātā i runga i te mata, ngā kōpae i ngā tapa, ngā whakamāmā i te whakamātautau i te hōhi, i ngā rereke o te whakamātautau i te wāhi o te pōkai i tāwhai ai ki te rākau. Mā te whakamātautau i ēnei raru i mua, ka whakamāmā ai ngā pātā mātātoko.

Te Mātāpono o te Whakamātau: Ngā Rōpū RPM, Te Whakamātau o te Tāwhai, me te Pakaru o te Hōhi

Inā he whakamātau o ngā mea i te hāere haere, ka piki ake te kaha o te whakamātau o te rorohiko i te tapawhā o te hāere. Nō reira, he iti anō te piki i te RPM, ā, ka piki tonu te whakamātau o te whakamātau i ngā kōpae. He tauira, he kōpae rēsini 125 mm e hāere ana i te 10,000 RPM, ka tīmata te whakamātau o te rorohiko i te 15,000 psi, e tātai ana i te whakamātau o te rorohiko i te rēsini. I tēnei wā anō, inā piki ake ngā hāngā i te 300°C, ka tīmata ngā rēsini fenolika ki te pakaru. Ka māmā ake te hanga o ngā kōpae, ā, ka tīmata ngā rūrū iti ki te whakawhitinga i te kōpae. Ko tēnei whakawhitinga o te whakamātau o te rorohiko me te piki o te hāngā, he rite tonu ki te pakaru tūtahi o te wāhanga. Kia whakamātau i tēnei, he mea nui te whakamātau i ngā rārangi RPM i tohua mai e ngā kaiwhakamahi. I tēnei anō, he pai hoki te whakamātau i ngā wā pātua iti i waenganui i ngā mahi whakamātau, kia māmā ake te hāngā. Kua kitea e tātou i ngā wā maha kua piki ake ngā tangata i ngā hāere i tohua mai, ka piki tonu te pakaru o te hāngā i te wā iti atu i te hāere i tohua mai, nō reira, he rite tonu te whakamātau i ngā rārangi RPM hei ara pai rawa atu hei whakamātau i ngā pakaru i te whare mahi.

Te whakamātautau i mua i te whakamāhi, me te whakamahi tika o ngā pātōrō kōkiri

Te rārangi whakamātautau ā-kirihau me ā-tiro: ngā pātāhanga, ngā whānanga, me ngā pākanga ki te pū

Me whakamātautau kē ngā pātōrō kōkiri i mua i te whakamahi. Me whakamātautau kē i rō ake i ngā wāhi e mā ana kia pai ai te tiro, ā, me whakawhānui i te pātōrō i te hāngī kia kitea ai ngā pātāhanga iti e kore pea e kitea i tēnei wā. Me whakaputangia te pātōrō ki tēnei wāhi pāpā, kia whakamātautau ai mēnā he whānanga. Me tiro hoki i te whānanga o te pū – he pākanga, he whakamā, he rere kē o ngā whakamāmā, he raru e noho ana. Kāore he whānanga i te rā whakamutunga o te pātōrō, ā, me whakamātautau anō ngā whakamātautau haumaru pērā i ngā whakamātautau o EN 12413, me ngā whakamātautau o ANSI B7.1. Me whakakīkī ngā mea katoa e pā ana i tēnei, ahakoa he iti ngā pākanga. He aha? Nā ngā whakamātautau i tēnei tau i te Journal o ngā Whakamāhi Haumaru, ko ngā raruraru e whitu i te tekau i ngā wāhi ā-mātā, he timatanga mai i ngā raruraru iti i wehea kē i tēnei wā o te whakamahi. Mēnā kāore koe e whakamāhi i tēnei wāhanga – he hapa nui. Kāore ngā whakamārama i ngā wā e tāwhai ana i te whakamāhi, inā rānei ka raru te taputapu i te raru iti.

Te Whakamahi i te Tātai Whakauru Tika me ngā Whakaaetanga o ngā Pāpātanga i runga i te EN 12413

Ko te whakauru tika he take matua mō te whakamāhi haumaru. Me whakamāhi i te rōrahi o te pāpātanga i te rōrahi o te arbor o te kōwhiri—kāore he whakamāhi i ngā kōwhiringa, i ngā wāhanga e taea ana te whakauru kia tāwhai ai ngā rōrahi rerekē. Me whakamāhi anake ngā pāpātanga kaha, kāore he pāpātanga kāore i te pakaru, ā, me whakamāhi i ngā pāpātanga e whakaae ana i te EN 12413, ā, ko tēnei te whakamārama i te rōrahi iti (⅓ o te rōrahi o te pāpātanga), te whakamārama i te whakamātautau, me ngā āhua o te whāriki kia whakamāhi ai te hāngā whakauru tāwhai.

Whakamātua te rōrō i te wāhi tāwhai i waenganui i ngā papa—kāore e whakamāhinga, kāore hoki e whakamātau i te rōrō ki te whānanga tāwhai. Whakamātua he whakamātautau 30 hēkona i te RPM iti rawa i muri i tēnei ārai haumaru i mua i te whakamātau i te taonga.

Te āhua o te whakamāhi: Te whakamātua i te hāere, te whakamātua i te whakauru, me te pūmau o te taonga

He aha te take kia whakamāhinga i te RPM o mua? Ko tēnei te take tuatahi mō te whakamāhinga o te rōrō kāpene

Ko te whakamāhua i te RPM o mua i te rere tāwhai ake he take tuatahi tonu i ngā pōro e pakaru ana i te wā o te whakamāhi. Ina huri te taputapu i te kaha, ka hanga i ngā whakamāngōnga rerekē ki te matū o te pōro. Ko ēnei whakamāngōnga e whakamāngō ana i ngā wāhi mātāmua, pērā i te wāhi o te pū o te pōro, i ngā hapa o te whananga. I te wā e tāwhai ana ngā matū i ō rātou pūkenga, ka pakaru tonu te pōro i roto i ngā wāhanga iti o te herengi. Ka taea ngā wāhanga e rere mai ana te hīkoi i ngā hau o te kaha i te 200 km i te hāora, ā, kāore ngā taputapu haumaru tātai e whakamāhi ai hei whakamāhi. I mua i te whakamāhi i te kōpae huri, tātai i te kaha o te taputapu i tēnei wā kia rite ki ngā kōrero kei te pōro anō. Kāore e whakamāhi i ngā pōro e rite ana i te rahi i runga i te whakaahua anō.

Ngā tikanga haumaru mō te tāpiri, te āhua, me ngā tikanga whakamātātari hei whakamāmā i te whakamāngōnga o te taha

Me whakaputangia te pōro i tēnei āhua kia pātata ki ngā āhua e tapahia ana, me te whakamahi i tēnei āhua o te hāngā i tēnei wā katoa. Kāore he whāinga kia whakamāni ai, he rere ai, he whakawhānui ai i te mata o te pōro i te wā o te tapahi. Inā he ngākau pūmau ngā kaha o te tāwhai i te pōro, ka whakamāhi ai i ngā āhua o te whakarere, ā, ko ngā āhua o te whakarere nei e whakamāhi ai i ngā wāhi o te rākau e whakamāhi ai i ngā āhua o te hāngā, ā, ko ngā āhua o te hāngā nei e whakamāhi ai i ngā āhua o te hāngā. Ko tēnei hāngā anō e whakamāhi ai i ngā kōpae o te hāngā i tēnei āhua. Me whakamahi i ngā āhua o te hāngā i raro i ngā 15 degrees i ngā wā katoa i tēnei wā. Ko ngā kōpae e whakamāhi ai i tēnei āhua i tēnei wā, me whakamahi i ngā kōpae e whakamāhi ai i ngā kōpae e rua ngā kōpae o te kōpae. Ko ngā āhua o te hāngā hoki e whakamāhi ai i tēnei āhua, ā, ko ngā 2 ki ngā 3 centimetres i te sekoni he pai tonu i te wā e mahi ana i ngā kōpae o te hāngā. Mēnā he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua rerekē, he āhua r......

Ngā Rākau Whakamātua Āki Āki me ngā Whakamātua Pakaru mō te Whakamahinga i ngā Pōro Tāwhai

Ko ngā rākau whakamātua āki āki he rākau whakamātua i te mutunga o te huarahi i te whakamātua i te haumātua i ngā wāhi mahi, ahakoa me whakauru kē i a ia ki te whānui ake o ngā whakamātua. Ko ngā take matua ko ngā karu whakamātua e whakamātua ana i te whakamātua ANSI Z87.1 me ngā whakamātua ki ngā taha, ā, he tino pūmau i ngā mahi i reira e whāia ana ngā whakamātua i ngā wāhi e tū ana. Mō ngā mahi tāwhai e whāia ana ngā whakamātua matatū, ka hāngā ngā whakamātua katoa mō te kanohi. He tino pūmau ngā ringaringa hoki – me whakamātua ngā ringaringa e tātari ana i te ISO 13997 Level A2 hei whakamātua i te tāwhai. Ko ngā kākahu e tātari ana i te tangata he rite tonu te pūmau. Kāore ngā kākahu whānui e taea te whakauru ki ngā rākau, nō reira he pai ake ngā kākahu e tātari ana i te tinana, kāore he wāhanga whānui pērā i ngā rākau roa, ngā kākahu whakamātua, me āhua atu. Me noho mai ngā taonga kākahu i te kāinga i ngā rā mahi, nā te mea he rere kē tēnei i tēnei, tēnei anō he taonga iti pea, engari he whakamātua tonu i ngā wāhi e neke ana.

Ko ngā whakamātautau pūkenga te rārangi tuatahi o ngā whakamārau ki ngā whakamāhinga. Ko ngā kōwhiringa ahi e whakamāmātia ana he pai hei whakamātua i ngā taputapu mātātoko i te wā o ngā mahi. Ko ngā pūnaha vākūm i tāwhai mai i ngā taputapu e tātai ana i te 95% o ngā pārāwaha i te rere, ā, ko tēnei he rongoā mai i ngā raraunga o OSHA i te tau 2023. Ko ngā whakamārau whakamāmātanga kōrero e whakamāmātia ana ngā rere kōrero kia kore ai ngā kaimahi e whakamāhinga i te 85 decibels A-weighted. Me whakamātau ngā wāhi mahi kia tūpākihi, ā, ko tēnei te mea matua. Ko ngā kōwhiringa māgnetik he pai mo ēnei whakamāhinga, ā, ko ngā kōwhiringa tāwhai, ngā kōwhiringa tāwhai, ngā kōwhiringa tāwhai rānei he pai ake mo ēnei atu. Me whakamātua ngā whakamātua whakamātua kia tū tonu i te wāhi e taea ai te tātai tonu i te wā e hiahia ana. I te whakamātua i ēnei whakamātautau pūkenga i ngā taputapu whakamātua tangata, ka whakamāmātia te maha o ngā whakamāhinga i te 74%, i te rere i te whakamātua i ngā taputapu whakamātua tangata anake. Engari, ko tēnei anake te hāngai i te wā e tū tonu ana ngā mea katoa i ngā whakamārama o te kaitātai i ngā whakamārama o te whakamātautau i te wā o te whakamāhinga.
