Te hoahoa ariā o te peera miihini aero

Ko ngā miihini rererangi te ngākau o ngā waka rererangi, ā, ko tā rātou mahi, te haumaru me te pono e whakatau tika ana i te mahi, te roa o te ora me te pono o ngā waka rererangi, ā, ko te mahi peera tētahi o ngā mea nui e pā ana ki te roa me te pono o ngā miihini rererangi.

 

Mīhini rererangingā peeraHe uaua ngā āhuatanga mahi, inā koa ko ngā peera porotaka, me tutuki ngā whakaritenga o te pāmahana teitei, te tere teitei, te mahi pumau (he pai mō ngā kawenga māmā, ngā kawenga taumaha, te tere whakatere me te whakaroa tere, ngā kawenga ru, ngā kawenga wiri, me ētahi atu), te pono teitei me te roa o te ora. I tēnei wā, he maha ngā rangahau kua mahia mō ngā peera miihini aero, te momo peera matua me te hoahoa tawhā matua, te tikanga whakahinuhinu me te hanganga flanging, te hanganga pute, te koki gasket, te hangarau maimoatanga mata, te tikanga whakamahi whakakotahi peera, me ētahi atu. He pānga nui ki tana mahi, ka taea e te hoahoa whaitake te karo i te pakaru wawe ongā peera, whakapai ake i tana mahi me te whakaroa i tōna roanga mahi. E whakaatu ana tēnei pepa i ngā āhuatanga motuhake o ngā peera miihini rererangi, me te whakarōpū i ngā āhuatanga awe me whai whakaaro ki te tukanga hoahoa peera.

Ngā āhuatanga motuhake o ngā peera miihini aero

Ngā āhuatanga hanganga:

Ngā peera miihini aero: e ai ki te waahanga whakamahinga, ka taea te wehewehe kia toru nga waahanga: nga peera porowhita, nga peera pouaka tuku taputapu me nga peera pouaka whakaheke.

1. Te peera o te miro

Ka tautokohia e ngā peera porowhita ngā rotor pā miihini, ngā rotor whakaputa hau me ngā rotor tāpoi hiko, ā, he maha ngā wā ka whakamahia he huinga o ngā peera pōro whakapā koki-toru me ngā peera roera porotaka, ka mau te kawenga tuaka me te kawenga radial o te rotor e ngā peera pōro whakapā koki-toru, ka mau ngā kawenga radial anake e ngā peera roera porotaka, ā, ko ngā āhuatanga mahi o ngā peera porotaka ko te tere hurihuri teitei (uara dn tae atu ki te 2.6 × 106 mm · r/min), te pāmahana teitei (180 ~ 250 °C, he wā poto ake i te 300 °C), te kawenga tuaka nui, te kawenga māmā wā poto me te taumaha i te ahunga radial, te ahunga whakarerekētanga kawenga tuaka me te wāhi tāutanga kiato. Nō reira, he teitei ngā taumata manawanui o ngā peera porotaka, ko te tikanga kāore i raro iho i te taumata P4, ā, he tino whakaritenga anō hoki mō te tika o te miihini o ngā roera porotaka; Hei tāpiri, ko te nuinga o ngā peera porotaka he mea whakahinuhinu i raro i te mowhiti, e hiahia ana ki te hoahoa motuhake e rite ana.

 

2 Te peera pouaka whakawhiti taputapu

 

Ka tautokona e te peera o te pouaka taputapu tāpiri te rotor taputapu o te pūnaha tuku taputapu, ā, ko ōna āhuatanga mahi he iti te kawenga, he iti te pāmahana (120 ~ 150 °C), me te tere hurihuri iti (kaua te uara dn e neke ake i te 1.5 × 106 mm · r/min）。

 

3 Perehi pouaka whakaiti

 

Ka tautokona te huihuinga taputapu whakaiti e te peera pouaka whakaiti, ko ōna āhuatanga mahi he kawenga nui, he tere iti me te pāmahana iti (120 ~ 150 °C).

 

Ngā whakaritenga whānui

Nā te āhua motuhake o te taiao whakamahi me ngā āhuatanga mahi o ngā miihini aerospace, he tino pakari ake ngā whakaritenga whānui mō ngā peera i ērā o ngā peera noa, ā, ko ngā whakaritenga e tika ana koia ēnei.

 

1. Ātete ki te pāmahana teitei i te wā e tū ana te waka

 

I te wā e oma ana te mīhini, ka whakaurua te hau matao hei whakamatao i ngā mata, ngā peera me ētahi atu wāhanga, ā, ka whakamataohia hoki ngā peera e te hinu whakahinuhinu. Heoi, i muri i te whakawetonga, kāore e mahi ēnei mahi whakamatao, ā, ka tukuna te wera o te tāpine ki te peera mā te whare peera me te pou, ka hua ake he pikinga tere o te pāmahana o te peera i roto i te wā poto, inā koa ka piki te pāmahana peera o te pito wera o te mīhini i runga i te āhua rerekē, ā, e whakaatu ana ētahi raraunga aroturuki mīhini ka eke te pāmahana peera ki te 350 °C.

 

2. Te kaha o te whakakorenga hinu whakahinuhinu

 

Ko ngā āhuatanga tuku hinu whakahinuhinu o ngā peera miihini aero e wehea ana kia rua ngā wāhanga matua:

1) I mua i te tīmatanga o te miihini ki te mahi noa o te pūnaha hinu whakahinuhinu, kei roto i te āhua rere makariri, he tere iti, he iti te kawenga;

2) I te wā e oma ana te mīhini, ki te kore e taea e te pūnaha hinu whakahinuhinu te tuku tonu i te hinu nā ētahi take motuhake, ā, me mahi tonu te mīhini mō tētahi wā, ka noho te peera i roto i te āhua o te hinu ngoikore, ka maroke rānei te mahi, ā, kāore e taea te whakahinuhinu pai me te whakamatao. Hei whakarite i te haumaru rere, me whai kaha ngā peera ki te mahi tonu i te āhua noa mō tētahi wā kua whakaritea me te kore e pakaru me te kore he hinu whakahinuhinu.

 

3 Te mahi toi pai

 

Mīhini rererangingā peeraMe whai tukatuka pai, mahi huihui, me ngā āhuatanga mama. Hei whakaiti i te uauatanga o te huihuinga, me iti rawa ngā wāhanga e hiahiatia ana e ngā miihini aero, ā, me whai tautoko rapa te poupou i te tūranga tautoko hei whakatika i te tere matua o te rotor, ā, kua whakaritea ngā ārai kiriata hinu hei pehi i te wiri rotor, ka nohoia e ēnei e rua te wāhi radial. Hei penapena i te wāhi radial hei whakanui ake i te maha o ngā huānga hurihuri me te whakapai ake i te kaha kawe, ka whakauruhia te mowhiti o waho o te peera ki te tautoko rapa o te whare tīwhana me te ārai kiriata hinu. Hei whakaiti i te maha o ngā wāhanga me te whakaiti i te uauatanga o te huihuinga, ka whakauruhia te tautoko whare tīwhana, te flange whakairi me te awaawa mowhiti rapa kiriata hinu ki roto i te mowhiti o waho o te peera, engari he raruraru anō hoki pēnei i te uauatanga o te hoahoa, te kaha hanganga iti, me te whiriwhiri rauemi me te tukanga whakaputa tino pakari.

 

4 Pūnaha whakaū kounga matatau

 

Haunga ngā ariā hoahoa matatau me te tika o te tukatuka, me whakawhirinaki hoki ki te pūnaha whakaū kounga matatau tae atu ki ngā paerewa tukanga, ngā taputapu tukatuka, te tirotiro kounga, ngā kaiwhakahaere, te manatoko whakamātautau, te tiwhikete kounga me ētahi atu āhuatanga.
