Me pēhea te whiriwhiri i ngā peera roera mō ngā mahi ahumahi

Kupu Whakataki

I roto i ngā taputapu ahumahi, he nui atu ngā pānga o te kōwhiringa peera roera i te taunga me te hurihanga anake: ka pā ki te kaha kawenga, te whakaputa wera, ngā wā tiaki, me te mōrearea o te wā whakatā utu nui. Nā te mea he rerekē ngā huarahi e whakahaere ai ngā momo peera rerekē i ngā kawenga radial, ngā kaha tuaka, te tere, te he o te tūnga, me te poke, ko te whiriwhiri i te mea tika me taurite ngā āhuatanga mahi ki ngā āhuatanga hoahoa kaua e whakawhirinaki ki te utu, ki te tikanga rānei. E whakamārama ana tēnei tuhinga i ngā āhuatanga kōwhiringa matua, ngā tauwhitinga i waenga i ngā hoahoa peera roera noa, me ngā pātai mahi me pātai e ngā kaihangarau i mua i te tohu i tētahi peera mō te ratonga ahumahi tono nui.

He aha te hiranga o ngā peera roera i roto i ngā tono ahumahi

Ko ngā peera roera te tūāpapa o ngā wāhanga hurihuri i roto i ngā mīhini ahumahi taumaha. He rerekē te hanganga mai ingā peera pōronā te āhua o te hononga-rārangi, e āhei ai rātou ki te tohatoha i te ahotea ā-pūkaha ki runga i te mata nui ake. Nā tēnei rerekētanga hoahoa taketake ka taea e ngā peera roera te whakauru i ngā kaha kawenga radial me te axial teitei ake.

Mā te whiriwhiri i te hoahoa peera roera tika ka whakatau tika i te pono o te pūnaha, te whai huatanga o te pūngao, me te roa o te mahi. Mā te tukanga whiriwhiri pakari ka taea e ngā pūnaha miihini te mahi tonu i raro i ngā āhuatanga ahumahi uaua me te kore e pāngia e te pakaru nui, e hiahiatia ana rānei ngā wawaotanga tiaki nui rawa atu.

Pānga ki te utu katoa o te mana whakahaere

Ko te utu tuatahi mō te hoko i tētahi peera roera he 10 ki te 15 ōrau noa iho o tōna Utu Katoa mō te Mana (TCO). Ko te toenga 85 ki te 90 ōrau i ahu mai i ngā mahi tiaki, ngā tikanga whakahinuhinu, me te pānga pūtea o te wā kore mahi i whakaritea.

Hei tauira, mēnā ka pakaru wawe te peera i roto i te mīhini whakarewa tonu, i te mira pepa rānei, ka tere te ngaronga o te hua neke atu i te $25,000 ia hāora. Nō reira, ko te arotau i te kōwhiringa peera i runga i te manawanui o te huringa ora, kaua i te utu kotahi tonu, he mea nui ki te hangarau me te pūtea.

Ngā tono e hiahiatia ana te mahi tino pai

He nui ngā wero kinematic me ngā wero taiao e pā ana ki ngā rāngai ahumahi taumaha e pana ana i ngā peera roera ki ō rātou rohe hoahoa tino tika. Hei tauira, ko ngā pou matua o te tāhū hau, ka pāngia ngā peera roera porowhita e ngā kawenga hihiri nui e neke atu ana i te 5 meganewtons (MN), i te wā e mahi ana i ngā tere hurihuri iti me te mau tonu i te piko hanganga teitei.

Waihoki, ko ngā mīhini keri konganuku me ngā mira hurihuri maitai e hiahia ana ki ngā peera e kaha ana ki te tu atu i ngā kawenga ru nui me te poke matūriki nui. Ko ēnei tono e hiahia ana ki ngā kōtaha ara rere motuhake, te mahi whakarewa matatau, me ngā otinga hiri pakari hei ārai i te pakaru kino me te ngenge wawe.

Me arotake te āhua o ngā tawhā whakahaere i mua i te tātari whakatairite i ngā waitohu peera, i ngā tauira rānei. Me whakamāori ngā kaihangarau i ngā hiahia ā-tinana o te mīhini ki ngā whakatakotoranga kinematic me te taiao tika hei whakawhāiti i ngā kōwhiringa hoahoa e wātea ana.

Te kawenga, te tere, te hē o te whakatakotoranga, te pāmahana, me ngā āhuatanga poke

Ko ngā taurangi matua e ārahi ana i te hoahoa o te peera ko ngā whākawe kawenga radial me te axial, ngā tere whakahaere, te kore taunga o te pou, ngā pāmahana taiao, me te urunga mai o te poke. Ko te maitai peera paerewa (pēnei i te 52100) ka mau tonu te pumau o ngā āhuatanga tae atu ki te 120°C (250°F), engari ko ngā momo motuhake kua pumau te wera e hiahiatia ana mō ngā taiao e eke ana ki te 200°C ki te 350°C.

Ko ngā tawhā tere, e arotakehia ana mā te whakamahi i te uara ndm (te whānui o te pitch i roto i ngā mirimita i whakareatia ki te RPM), e whakatau ana i ngā whakaritenga whakahinuhinu me te whare herehere. Ko ngā tono neke atu i te 500,000 ndm te tikanga me whakamahi whare herehere me ngā pūnaha hinu toiawhio kia tika te mīhini, kaua ki te tākai hinu paerewa hei whakahaere i te whakaputanga wera me ngā kaha centrifugal.

Ngā rerekētanga i waenga i ngā peera porotaka, porowhita, whakarara, me ngā peera ngira

Ko te āhua motuhake o ngā wāhanga hurihuri e whakatau ana i ngā āheinga mahi matua me ngā herenga o te peera. He tino pai ngā peera roera porotaka i roto i ngā tono kawenga tere-teitei, taumaha, engari he iti noa te tautoko kawenga tuaka. Ka taea e ngā peera roera porowhita te whakauru i ngā kawenga taumaha, ā, ka manawanui ki te he o te pou, i waenga i te 1.5 me te 2.0 nekehanga.

Ka taea e ngā peera roera whakarara te whakahaere i ngā kawenga taumaha ā-ira me ngā kawenga tuaka kotahi-angi i te wā kotahi, ā, he maha ngā wā ka whakatakotoria ki ngā takirua rerekē hei whakahaere i ngā kaha ā-angi rua. He nui te ōwehenga roa-ki-te-diameter o ngā peera roera ngira, e whakarato ana i te kaha kawenga ā-ira tino pai i roto i te kōpaki ā-ira tino herea.

Te whakawātea ā-roto, te whare herehere, te hiri, me ngā kōwhiringa rauemi

Ko te āputa o roto, te hoahoa o te whare herehere, te hiri, me te hanganga rauemi e tohu ana i ngā whakaritenga iti. Ko te āputa o roto pūtoro, mai i C2 ki C5, me whai whakaaro ki te whānui o te wera mahi.Ngā tono mōtini hikoMe tautuhi pinepine te āputa C3 hei whakauru i te rerekētanga pāmahana 10°C ki te 15°C i waenga i ngā mowhiti o roto me o waho.

Ko ngā rauemi o te whare herehere he rino tāmi ki te parahi mīhini, he polyamide whakakaha muka karāhe (PA66) rānei. Heoi, ko ngā whare herehere PA66 he mea here ki ngā pāmahana mahi tonu i raro i te 120°C, ā, ka pirau pea i te aroaro o ētahi hinu whakahinuhinu. Ko ngā hiri whakauru he parenga tuatahi ki ngā poke, ahakoa me whai hiri whare o waho pakari tonu ngā taiao kua tino poke.
