He aha ngā whakaritenga motuhake mō ngā peera o te miihini rererangi, me pēhea te whakatutuki i te ātete pāmahana teitei me te whakahinuhinu?

 

Tuatahi, kia mārama tātou ki ngā āhuatanga whakahaere o ngā miihini rererangi:

 

1. Te tere tere, ko te tere o te miihini rererangi whānui neke atu i te 18000 rpm, ā, he tino teitei ngā whakaritenga mō ngā rauemi i taua tere teitei.

 

2. Te pāmahana teitei, he tino teitei te pāmahana whakahaere o te miihini, ka eke pea te pāmahana whakahaere o te peera ki te 300 °C, me kaha te rauemi peera ki te tu atu i te pāmahana teitei.

 

3. He tino pono, ahakoa he waka rererangi ā-iwi, he waka rererangi whawhai rānei, he tino teitei ngā whakaritenga mō te pono, ā, he iti noa te rerekētanga o te puna he mea e pā ana ki te ora o te tangata.

 

Nā te meate pāmahana whakahaere teitei o te peera, he mea hanga te mowhiti o waho ki te rauemi AISI M50 he ātete teitei ki te pāmahana me te pumau pāmahana teitei, e taea tonu te eke ki te pakeketanga 58HRC i te 300°C.

I te tere tere, nā te mea kei te hurihuri te mowhiti o roto o te peera, he nui rawa te kaha o te centrifugal, ā, ko te wāhanga whakawhiti o te mowhiti o roto o te peera e mau ana i te ahotea kume, nō reira kāore e taea te hanga i ngā kapiti moroiti i runga i te mata o te mowhiti o roto kia kore ai e horapa te kapiti i raro i te ahotea kume, nō reira he maha ngā wā ka whakamahia te rauemi AISI M50NiL hei mowhiti o roto.

 

Nā te tere tino tere, hei whakaiti i te kawenga tāpiri e kawea mai ana e te kaha whakatere o te pōro maitai, ko te rauemi uku he mama te taumaha me te pakeke teitei, pērā i te silicon nitride (Si3N4) te titanium carbide (TiC rānei), e whakamahia whānuitia ana hei rauemi pōro maitai, ā, i ētahi wā hei whakanui ake i te ātete kakahu o ngā mowhiti o roto me waho o te peera me te whakaiti i te waku, ka rehuhia hoki ngā ara mowhiti o roto me waho ki ngā uku.

 

Ka taea e te pāmahana o te mīhini te neke atu i te 300 °C, ko te pāmahana teitei rawa atu i te 1500 °C, ko te pāmahana e tika ana kia mau ko te 300 °C anake. Koinei te painga o te pūnaha whakahinuhinu, ko te mahi matua hoki o te pūnaha whakahinuhinu peera ko te whakamatao.

Ko tētahi wāhanga o tēnei he whakahinuhinu, he rite tonu te whakahinuhinu o te peera miihini ki te whakahinuhinu o ngā peera whānui, nā te mea he tere rawa te tere o te peera, kāore e taea te whakamahi i te hiri whakapā, nō reira he tikanga hiri labyrinth te peera miihini, engari he pai ake te hinu whakahinuhinu e whakamahia ana e ia, nā te mea he teitei rawa te pāmahana whakahaere, he ngāwari te waikura me te pirau o te hinu whakahinuhinu whānui, nō reira he hinu hangai MIL-PRF23699HTS te nuinga o te wā.
