Ngā Tohutohu Whakahaere o te Whakaranu Korehau

Kupu Whakataki

I muri i te hokonga mai o te maha o ngā wheketere i tētahi mīhini whakamarara korehau maitai, he maha tonu ngā wā ka tūtaki rātou ki te raruraru kotahi: he matatau, he pai hoki te whirihoranga o ngā taputapu, engari kāore ngā kaiwhakahaere e mōhio me pēhea te whakamahi tika. Ka hua ake tēnei i te iti o te whai huatanga whakaputa me te kounga hua kore pumau, i ngā hapa whakahaere rānei e kino ai ngā taputapu, e whakaroa ai te whakaputa, ā, e hanga ai hoki i ngā tūponotanga haumaru.

Ina hoki, ehara i te mea uaua te whakahaere i tētahi mīhini whakamarara korehau maitai. Ko ngā mātāpono matua ko te whai i te tukanga, te aro ki ngā taipitopito, me te karo i ngā hapa noa . Ahakoa he pakari te hanganga maitai katoa, ko te whakahaere tika te mea e whakanui ana i ōna painga, e whakaroa ana i te roa o te ora o ngā taputapu, ā, e whakarite ana i te haumaru o te whakaputanga.

He tuhinga tēnei mā ngā kaiwhakahaere tīmata me ngā kaiwhakahaere awheawhe. E whā ngā wāhanga matua e kapi ana i tēnei tuhinga: te whakarite i mua i te mahi, ngā tikanga whakahaere paerewa, ngā hapa noa hei karo, me ngā whakatūpato haumaru. Whāia tēnei aratohu kia tere ai te whakahaere me te kore e roa te wā e mutu ai te mahi, te mahi anō, te pakaru rānei o ngā taputapu.

1. Te Whakarite i mua i te Whakahaere: 3 Ngā Hipanga hei Ārai i ngā Raru i te Tīmatanga

He mea nui te whakarite i mua i te mahi hei ārai i ngā hapa whakahaere, hei whakarite hoki i te haumaru o te whakaputanga. Ahakoa te tere o te kaupapa whakaputa, kaua e mahue ēnei mahi e toru.

1.1 Tirotiro Taputapu – Arotahi ki ngā Wāhanga Matua e 3

① Tinana me te Tāke Kowiri tira:

• Tirohia te tinana mō ngā karawarawa, ngā wāhanga rānei e kore e tika ana

• Me whakarite kia ma te pakitara o roto o te tāke, kia kore he toenga rauemi mai i ngā puranga o mua (mā te horoi pai ka ārai i te whakawhiti parahanga)

• Mō ngā tāke kua orohia ki te whakaata, karohia te pa atu ki ngā mea koi ka rakuraku pea.

② Ngā Wāhanga Matua:

• Tirohia mēnā kei te wetekina, kei te tawhito rānei ngā mata o te whakakorikori (te mata waru tere-iti, ngā rakau whakamarara tere-nui).

• Me whakamana kei te pai te āhua o ngā waru PTFE

• Tirohia ngā hiri miihini me ngā hiri taupoki mō te pakaru, te turuturu rānei

③ Ngā Pūnaha Āwhina:

• Tirohia mēnā he mārama te pūnaha korehau (papu korehau, paipa korehau) ā, he rite tonu te pānui a te ine korehau.

• Manatokohia kei te pai te mahi a te pūnaha hiki waipēhi me te kore e piri

• Tirohia te pūnaha whakahaere hiko, ngā waea, me ngā taputapu ātete-pahū (mō ngā tono matū)

1.2 Te Whakarite Rauemi – Āraia ngā Take Rauemi e Pā Ana ki te Mararatanga

① Te Maimoatanga-Mua o ngā Rauemi:

• Ngā rauemi mata e hiahia ana kia horahia i mua hei tango i ngā poke me ngā mea whakaemi (ina koa ko ngā whakakī me ngā tae)

• Mā tēnei ka ārai i ngā rauemi kua whakaemihia kia kaua e aukati i ngā mata o te kaiwhakaoho, e pā kino rānei ki te ōritetanga o te mararatanga.

② Whakahaere i te Rōrahi Whāngai:

• Kia tino whai i ngā whakaritenga mō te kaha o ngā taputapu mō te uta rauemi

• Kaua te rahinga whakakī tuturu e neke ake i te 70-80% o te kaha o te tāke

• Whakatapua he wāhi nui mō te tango hau korehau me te whakawhānui i ngā rauemi i te wā e whakaohooho ana

• Mā te nui rawa o ngā rohe ka waipuke pea ngā rauemi, ka kore rānei e tutuki te korehau e hiahiatia ana.

③ Raupapa Tāpiri Rauemi:

• Tāpirihia ngā rauemi iti-matotoru i te tuatahi (te kapia turanga, ngā whakarewa)

• Kātahi ka tāpirihia mārire ngā rauemi matotoru (ngā whakakī, ngā tae)

• Ka ārai tēnei i te kohikohinga o ngā rauemi me te piri o te pakitara, ka whakapai ake i te whai huatanga o te horapa.

1.3 Te Whakarite Haumaru – Hangaia he Tūāpapa Haumaru Kaha

① Ngā Taputapu Tiaki Whaiaro (PPE):

• I roto i ngā mahi matū, me mau ngā kaiwhakahaere i ngā karapu ātete-waikawa/kawakore, ngā mōhiti haumaru, me ngā kākahu tiaki.

• Ārai i te pa atu o ngā rauemi ki te kiri, te tauhiuhi rānei ki ngā kanohi

② Tirotiro Taiao o te Awheawhe:

• Kia kore he paru, he rauemi mura/pahū rānei e karapoti ana i ngā taputapu.

• Me whakapūmau kei te tika te hauhautanga (ina koa ka whakamahia ngā whakarewa)

• Whakakorehia ngā tūponotanga mōrearea haumaru

③ Te Whakamātautau Kore-Utaina:

• I mua i te tīmatanga, whakahaerehia te taputapu me te kore rauemi mō te 1-2 meneti

• Tirohia mēnā he maeneene te hurihanga o ngā mata o te mīhini whakaoho, kāore he haruru rerekē

• Me whakarite kei te mahi tika te pūnaha korehau

• Me tīmata noa te uta rauemi i muri i te whakaū kāore he raruraru

2. Tukanga Whakahaere Paerewa: 5 Ngā Hipanga mō te Whakahaere Whai Hua me te Haumaru

Kia oti te mahi whakarite, whai i tēnei tikanga paerewa e 5 ngā taahiraa. Ka taea e te hunga tīmata te whakatutuki i te whakahaere tika, kia pai ai te kounga o te horapa me te haumaru o te whakaputanga.

Hipanga 1: Te Utaina o ngā Rauemi (Puhoi, Taurite, Ārai i te Tauhiuhinga)

1. Whakahohehia te pūnaha hiki waipēhi hei hiki mārire i te taupoki

2. Whakaū kei te tika te tūnga o te tāke

3. Āta utaina ngā rauemi ki roto i te tāke – nekehia mārire kia kore ai e tauhiuhi (ka poke te tinana o te maitai kore waikura, ā, me horoi anō hoki) ā, kia kore ai e pupū ake ngā rauemi ki raro.

4. I muri i te utaina, tirohia te roto o te tāke mō ngā paru, ngā mea whakaemi rānei

5. Whakahohehia te pūnaha hiki waipēhi hei whakaheke mārire i te taupoki

6. Maukati te taupoki kia mau kia kore ai e āraihia te hau

Hipanga 2: Te Whakahaere Korehau (Me whakarite kia tutuki ngā paerewa o te korehau, ā, karohia ngā mirumiru)

1. Whakakāhia te pūnaha korehau hei tīmata i te whakawātea

2. Aroturukihia te ine korehau kia eke ki te taumata e hiahiatia ana (te tikanga ≤ -0.098 MPa)

3. Ki te kore e taea te eke ki te taumata korehau, kati tonu, ka tirotiro:

   • Kua tika te raka o te taupoki?

   • Kua pakaru ngā hiri?

   • He turuturu kei roto i ngā paipa korehau?

4. I muri i te tautuhi me te whakatau i te raruraru, tīmata anō te tango i te korehau

5. Ko te wā horoi ka whakawhirinaki ki ngā āhuatanga o te rauemi – ko te tikanga he 5-10 meneti – kia tino tangohia ai te hau mai i te tāke.

Hipanga 3: Te Whakaohooho me te Mahi Marara (Tere Iti i te Tuatahi, Kātahi ka Tere Nui – Haere Tonu)

Kia tae te haumākū ki te taumata e hiahiatia ana:

1. Tīmatahia te pūnaha whakaoho i runga i te kaupapa "tere iti tuatahi, kātahi ka tere teitei".

2. Tīmatahia te mata waru tere-iti hei āta haere i te rauemi, hei ārai hoki i te piri o te pakitara.

3. I muri i te 1-2 meneti, tīmatahia ngā toki whakamarara tere-teitei

4. I runga i te matotoru o te rauemi, āta whakatikatikahia te tere (tere iti: 0-33 rpm, tere teitei: 0-2800 rpm – ka taea te whakarite VFD)

Ngā Kaupapa Whakahaere Matua:

• I te wā e horapa ana, me āta tirotiro i te āhua o te rauemi

• Ki te puta he haruru rerekē, he pupū ake rānei ngā rauemi, kati tonu, whakakorea ngā rauemi pupū ake, kātahi ka tīmata anō.

• Kaua e whakanuia te tere ki te mōrahi i te wā kotahi – ka pakaru pea ngā rauemi, ka nui rawa rānei te wiri, ka kino te tinana o te maitai kore waikura, ka whakakorikori rānei i ngā wāhanga.

• Ko te wā marara ka whakawhirinaki ki ngā whakaritenga rauemi – ko te tikanga he 20-60 meneti – kia rite te marara me te kore he matūriki

Hipanga 4: Te Whakatikatika i te Mana Pāmahana (Whakatikatikahia kia rite ki te Hiahia, Ārai i te Pirau o ngā Rauemi)

Mō ngā rauemi e hiahia ana kia whakahaerehia te pāmahana (hei tauira, te hiri silicone, te paru pākahiko lithium):

1. I te wā e whakaohooho ana, e horapa ana hoki, whakahohehia te pūnaha whakahaere pāmahana

2. Whakatikatikahia te pāmahana kia rite ki ngā whakaritenga o te tukanga rauemi (awhe whakahaere: 0-150°C / 32-302°F)

3. I te wā e whakamahana ana: whakanuia mārire te pāmahana kia kore ai e piki ohorere te pāmahana ka pakaru pea te rauemi

4. Ina whakamatao: tīmata wawe te rere o te wai whakamatao kia mau tonu te pāmahana pumau i roto i te awhe e hiahiatia ana

Kia mōhio: He tino whai hua te pūnaha whakahaere pāmahana kua hipokina ki te koti i runga i ngā tāke maitai kore waikura. He rawaka te tirotiro i ngā ine pāmahana auau – kāore e hiahiatia he whakarerekētanga auau, ā, ka pā pea ki te kounga o te hua.

Hipanga 5: Te Tukunga me te Horoi (Te Horoi Āta Hei Ārai i te Toenga)

Kia oti te horapa:

1. Whakamutua ngā toki horapa tere-teitei, kātahi ka mutu te mata waru tere-iti.

2. Whakawetohia te pūnaha korehau

3. Taria kia hoki te pēhanga o te tāke ki te taumata o te hau

4. Whakahohehia te pūnaha hiki waipēhi hei whakatuwhera i te taupoki

5. Mena kei a ia he pūnaha tukunga (pūwero waipēhi / papu taputapu matotoru-teitei), tīmatahia kia āta tukunga rauemi.

6. Ki te kore he pūnaha tukunga, ka whakaaetia te tukunga ā-ringa – kia kore he rauemi e toe ana.

I muri tonu i te tukunga:

• Horoia te tāke, ngā mata o te whakaoho, me te tinana o te kowiri tira

• Whakamahia he wai ma, he wai horoi koretake rānei hei muru i ngā toenga rauemi – kia aro nui ki ngā pakitara me ngā mata o te tāke.

• Ka ārai tēnei i te whakatiotanga o ngā rauemi me te waikura o ngā taputapu

• Kia oti te horoi, katia te taupoki ka whakamahia he tikanga tiaki puehu mō te mahi e whai ake nei.

3. Ngā Hapa Noa a te Tīmatanga: 5 Ngā Hapa hei Ārai

Ko te nuinga o ngā hapa whakahaere, te pakaru o ngā taputapu, me te ngoikore o te kounga o te hua i waenga i ngā tīmatanga ka puta mai i te kore e aro ki ngā kōrero e rima e whai ake nei. Mā te karo i ēnei mahanga ka penapenahia he nui te wā me te raruraru.
