Ngā peera miihini aero
Te whāngaimomo
He tere te tere o te porowhita o te miihini aero, he teitei te pāmahana o te pito wera, ā,te whārikiMe amo i te kawenga tuaka me te kawenga radial, nō reira ka wehea te peera kia rua ngā wāhanga: te peera tūtahi pana me te peera tūtahi kaukau: ko te peera tūtahi pana te tikanga e whakamahi ana i te peera pōro whakapā koki-toru hei amo i te kawenga tuaka me te whakahaere i te ātea tuaka o te stator hurihuri; Ko ngā peera tūtahi haereere ka amo noa i ngā kawenga radial, ā, nā te mea ka neke te rotor i te ahunga tuaka nā te whānui me te whakahekenga wera,ngā peera roera porotakakāore he rohe o te mowhiti o waho, o roto rānei, e whakamahia ana i te nuinga o te wā.
Ko ngā pouaka taputapu miihini aero e peia ana e ngā taputapu pupuhi, ā, ko ngā kawenga radial anake ka mau ki ngā peera, ā, he iti te whakawhānui wera o te rotor, nō reirangā peera roera porotakamengā peera pōro awaawa hohonuka tīpakohia te nuinga.
He nui te mana e tukuna ana e te pouaka whakaheke, ko ētahi o ēnei e whakamahi ana i ngā taputapu helical, ā, me kawe e ngā peera ngā kawenga radial me te axial, nō reirangā peera roera porotaka, ngā peera pōro awaawa hohonume ngā tohu-torungā peera pōro whakapā kokika tīpakohia te nuinga.
Ka whakamahia e ngā miihini aero ngā peera pōro pa-toru-ira mengā peera roera porotaka.
Ngā peera pōro whakapā koki-toru
I te wā e oma ana te mīhini aero, ka puta te kawenga radial me te kawenga axial ki runga i te miro, ā, ka whakatakotoria he huinga peera pōro ki te pūwāhi tūāpapa i mua i te miro hei pikau i te kawenga radial i hangaia e te tūnga o te kaha kore taurite o ia pou me te hurihanga tere-teitei, ā, i te wā kotahi ka pikau i te kawenga axial rerekē i waenga i te kaha hau o te pā me te compressor whakamua me te kaha hau whakamuri o te tāpine.
I te whakataurite i te hanganga o ngā peera pōro hohonu me ngā peera pōro whakapā koki-toru, ko te pokapū o te mowhiti o roto o te peera pōro whakapā koki-toru he rite ki te eccentricity axial Lo, e whakaiti ana i te āputa axial Ga me te nui o te rotor i te ahunga axial, ā, he māmā ake te whakahaere i te āputa axial o te oumu hurihuri o te miihini.
He mowhiti haurua-roto takirua te hanganga o te peera pōro pa koki-toru, ā, mā te hoahoa wehewehe mowhiti haurua-roto ka taea te tāuta i ētahi atu pōro, ka nui ake te kaha o te kawe.
Te whakataurite i te hanganga o ngā peera pōro whakapā koki me ngā peera pōro whakapā koki-toru, ka taea anake e ngā peera pōro whakapā koki te pikau i ngā kawenga tuaka kotahi-ara, ki te hiahia rātou ki te pikau i ngā kawenga tuaka rua-ara, me whakakotahi, ka nui ake te wāhi ka nui ake te papatipu; Ka taea e ngā mowhiti rua me te haurua o roto o ngā peera pōro whakapā koki-toru te pikau tika i ngā kawenga tuaka rua-ara, ka taea te penapena i te 50% o te wāhi me te kounga ki te whakataurite ki te rarangi rua, ki te rōpū rānei o ngā peera pōro whakapā koki tautoko, ā, he ngāwari ki te tāuta, he mea watea mō te hoahoa miihini.
Ka taea te wehe i te huihuinga whare herehere me te pōro o te peera pōro whakapā koki-toru mai i te mowhiti o waho, kia taea ai te whakamahi i te whare herehere totoka kotahi-wahi, he kaha ake, he pai mo te tere hurihuri teitei, he ngawari ake hoki te whiwhi i te tika miihini teitei ake; I te wa ano, ka ngawari ake te whakauru me te tirotiro i nga peera e te hanganga.
Ki te whakatauritea ki ngā peera roera porotaka miihini noa, he iti ake te diameter roera o ngā peera roera porotaka miihini aero, ā, ko ōna painga koia ēnei:
1) Ka taea e ia te whakaiti i te ātete o te roera ki te whakaoho hinu i te wā e mahi ana i te tere tiketike;
2) He iti te kaha ā-pūmau;
3) Ka taea te pupuri i te pēhanga whakapā e ranea ana ina iti te kaha radial hei karo i te paheke o te roera;
4) Nā te mea ka taea te wehewehe i ngā wāhanga o te wīra, te roera me te whare herehere, ka taea te whakamahi i tētahi whare herehere totoka, he kaha ake, he pumau hoki i te tere teitei.
Ngā peera roera porotakaKo ngā mowhiti o roto, kāore he flange, he whānui ake te mowhiti o roto hei whakauru i te nekehanga tuaka i waenga i ngā mowhiti o roto me waho nā te roa o te toronga wera i waenga i te pou me te mowhiti o roto o te peera, me te hē o te hononga i waenga i ngā mowhiti o roto me waho nā te hapa o te huihuinga tuaka o te huihuinga rotor i te wā huihuinga. Mena he iti te wāhi tāutanga, he whakaritenga motuhake rānei, ka taea te whakamahi tika i te pou, i te whare peera rānei hei whakakapi mō te mowhiti o roto kore flange.
Mīhini rererangingā peera roera porotakaHe maha ngā wā ka tūtaki ki ngā āhuatanga mahi o te kawenga radial iti, kāore rānei, o te kawenga radial, ā, he tino teitei te tere hurihuri, he ngāwari ki te paheke me te mirimiri i ngā roera, hei ārai i te paheke, he maha ngā wā ka whakamahia ngā ara reihi kore-porowhita hei whakatutuki i te kawenga radial o te peera, ā, he maha ngā wā ka whakamahia te tohatoha kawenga o ngā peera reihi kore-porowhita e rua.
Rauemi peera
He tino teitei te pāmahana o te taiao mahi o te peera tāpine miihini, ā, he mea tika kia whakamataohia te peera ki te nui o te hinu whakahinuhinu o ētahi rita ia meneti, engari ka taea tonu e te pāmahana mahi o te peera te eke ki te 250 °C.
Hei whakatutuki i ngā tikanga mahi pāmahana teitei, ko te mowhiti peera e whakamahi ana i te maitai 8Cr4Mo4V (M50) me ētahi atu maitai peera pāmahana teitei, ā, ka tukinotia ki te whakamahana pāmahana teitei, ahakoa ka eke te pāmahana peera ki te 400 °C i muri i te whakamutua o te miihini, ka taea tonu te whakarite i te mahi a te peera. Hei whakatutuki i te roa o te ora ngenge hurihuri, ko te pakeke o te mata o te rauemi peera me iti iho i te 60 HRC i te pāmahana rūma, ā, ka whakapakeketia te maitai 8Cr4Mo4V katoa mā te maimoatanga wera, engari he iti ake te pakari i te rauemi hanganga, ka arahi ki te pakaru o te ferrule ina nui te kaha centrifugal o te ferrule me te ahotea porowhita o te rakau. Nō reira, ko te uara dn neke atu i te 2.5 × 106 mm · r/min me hanga ngā peera ki te rauemi G13Cr4Mo4Ni4V (M50NiL), he pai ake te pakari o te matua.
Ko te rauemi o te whare herehere o ngā peera miihini aero he mea hanga i te maitai hanganga pēnei i te 40CrNiMoA (4030), ā, me whakakikorua te whare herehere ki te hiriwa hei whakaiti i te pakaru i te wā tīmatanga. He rite tonu te huānga hurihuri ki te rauemi ferrule, ā, ko tōna pakeke he rite tonu ki te ferrule, ā, i ētahi wā ka 1 ~ 2 HRC teitei ake i te ferrule. I ētahi wā ka whakamahia hoki e te pōro ngā rauemi uku pēnei i te silicon nitride, te alumina, me te zirconia.
