Ko te whiriwhiri i tētahi peera pōro whakapā koki mō te ratonga tere-rahi ehara i te mea mō te taurite i ngā ine, engari mō te whakahaere i te wera, te pakari, te utaina mua, me te ngenge i raro i ngā āhuatanga whakahaere uaua. Ka taea e ngā hapa iti o te whakatakotoranga te whakanui ake i te waku, te whakatairanga i te paheke, te whakapoto rānei i te roa o te oranga o te peera i mua i te taenga o te pūnaha ki tōna tere e hiahiatia ana. E whakamārama ana tēnei tuhinga i ngā āhuatanga matua e akiaki ana i te kōwhiringa, tae atu ki te koki whakapā, te rautaki utaina mua, te ahunga kawenga, te whakahinuhinu, me ngā rohe tere, kia taea ai e koe te aromatawai i ngā kōwhiringa peera me te mārama ake ki te pānga o ia whakatau ki te pono, te whanonga wera, me te mahi whānui o te mīhini.
He aha te pānga o te kōwhiringa o te whāriki pōro whakapā koki ki te pono
I roto i ngā taputapu hurihuri tere-rahi, ko te peera pōro whakapā koki te hononga matua i waenga i te tuku mana hihiri me te whare pumau. Mā te whiriwhiri i te hoahoa peera tika ka whakatau tika i te pono o te mahi me te pumau o te wera o ngā pūnaha pēnei i ngā miro taputapu mīhini, ngā mīhini turbo, me ngā kaiwhakaoho rererangi. Ina neke atu te tere hurihuri i te 1.5 miriona dN (te diameter o te poka i roto i ngā mirimita i whakareatia ki te tere i roto i te RPM), ka tino whaiti te tawhiti mō te hapa i roto i ngā whakatakotoranga peera, ka hiahiatia he tikanga whiriwhiri pakari.
Te tere, te utaina i mua, me te mōrearea o te rahunga
He tino kore-rārangi te whanaungatanga i waenga i te tere hurihuri, te utaina ā-roto, me te rahunga kino.ngā peera pōro whakapā kokiHei whakatere, ka panaia ngā wāhanga hurihuri e ngā kaha tohanga ki waho ki te ara rere o te mowhiti o waho. Ka whakarerekētia e tēnei mahi hihiri te koki whakapā mahi, ā, ka taea te whakanui ake i te utaina ā-roto whai hua tae atu ki te 30% i ngā tere neke atu i te 15,000 RPM.
Mena ka nui rawa te utaina pūmau tuatahi, ka puta te rere o te wera i tēnei pikinga hihiri, ka tere te pirau o te hinu whakahinuhinu me te pakaru wawe o te kiri. I tetahi atu taha, mā te utaina koretake ka paheke ngā pōro, kaua e hurihuri, ka nui te pakaru o te piri me te pakaru o te whare herehere. Ko te whakahaere i tēnei taurite te pūtake matua o te pono o te miihini mō te wā roa.
Ngā tikanga whakahaere hei tautuhi tuatahi
I mua i te aromatawai i ngā āhuahanga whāriki motuhake, me whakatū e ngā kaihangarau he takai tika o ngā āhuatanga whakahaere. Me mahere tēnei i ngā kawenga radial me axial mōrahi me te haere tonu, te ine i te awhe pāmahana whakahaere e tumanakohia ana, me te tautuhi i te huringa mahi.
Hei tauira, ko te porowhita e mahi tonu ana i te 24,000 RPM me whai rautaki whakahaere wera tino rerekē i te tikanga e whakahaere ana i ngā whakaterenga tere, ā-wā ki te 30,000 RPM. Mā te whakatū i ēnei tawhā taketake ka whakarite kia ahu mai ngā whakataunga e whai ake nei mō ngā koki whakapā me ngā rauemi i runga i ngā raraunga mahi ā-wheako kaua ki ngā whakatau tata mahi whānui.

Ko te whakamaoritanga o ngā tawhā mahi ki ngā whakatakotoranga whāriki ā-tinana me mārama hohonu ki ngā āhuahanga ā-roto me ngā here ā-mīhini. He mea hanga motuhake te whāriki pōro whakapā koki hei whakauru i ngā kawenga whakakotahi, engari ko te arotau i a ia mō ngā taiao tere-tiketike me whakarite tika i tōna hoahoa ā-roto.
Koki whakapā, āhuahanga, whare herehere, me te utaina mua
Ko te koki whakapā te taurangi āhuahanga matua e whakatau ana i te tohatoha kawenga me te kaha tere. Ko ngā whirihoranga tere-teitei paerewa e whakamahi ana i ngā koki whakapā 15°, 25° rānei. Ka whakaitihia e te koki 15° te ōwehenga hurihuri-ki-te-hurihuri, ka whakaitihia te waku ā-roto, ā, ka taea te tere hurihuri mōrahi, ahakoa ka whakararu i te pakari tuaka. Ka whakaratohia e te koki 25° he taurite, ka whakanui ake i te pakari tuaka me te whakaiti i te paepae tere mōrahi mā te 15% ki te 20% ki te whakataurite ki te momo 15°.
Hei tāpiritanga, he mea nui te hoahoa o te whare herehere; he maha ngā wā ka whakamahia ngā whare herehere māmā, he mowhiti-waho te arataki i ngā tono tere-teitei, he mea mīhini mai i te kapia phenolic, i te PEEK rānei. Ka whakaitihia e ēnei pūmua matatau te papatipu centrifugal, ka whakaitihia te waku ki ngā huānga hurihuri, ā, ka ārai i te haruru kino o te whare herehere i ngā tere tino nui.
Ngā herenga tere me ngā āhuatanga mahi
Ko ngā tere tere e tino whakahaerehia ana e te tauwehenga dN me te taunekeneke uaua o te waku ā-roto, te akomanga utaina-mua, me te whakahinuhinu. Hei whakatere i ēnei taurangi, ka whakawhirinaki ngā kaihangarau ki ngā tauwehenga mahi whakataurite hei whakataurite i te āhua o te peera me ngā tono kinematic o te tono.
| Koki Whakapā | Tere Mōrahi Whakatairanga | Te Kaha Utaina Tuaka Whānui | Arotahi Taupānga Noa |

Ko te paerewa ahumahi mōngā peera tikahe maitai chromium waro-teitei (pērā i te 52100, i te 100Cr6 rānei), e whakarato ana i te roa o te ora ngenge pai i raro i ngā āhuatanga taurite. Heoi, kei te piki haere te hiahia mō ngā tono tere-teitei ki ngā peera uku ranu, e hono ana i ngā mowhiti maitai me ngā huānga hurihuri silicon nitride (Si3N4).
E 60% te mama ake o ngā pōro silicon nitride i ō rātou hoa maitai. Mā tēnei whakaiti nui i te taumaha ka whakaitihia ngā kaha centrifugal me te paheke gyroscopic i te ara rere o waho, ka taea ai e ngā peera ranu te eke ki te tere 20% ki te 30% teitei ake i ngā momo maitai katoa. Hei tāpiri, ka whakakorea e ngā rauemi rerekē te mōrearea o te whakarewa makariri (galling) i raro i ngā āhuatanga whakahinuhinu taha, ā, ka whakaitihia te whānui wera i roto i te matua peera.
Ngā tikanga whakahinuhinu me ngā tauwhitinga
Ehara i te mea he mea tiaki noa te whakahinuhinu; he herenga hoahoa matua. He tino whai hua te whakahinuhinu hinu paerewa, ā, he māmā ake te hoahoa o te whare, engari he iti noa iho te tere whakahaere o te 1.0 ki te 1.2 miriona dN nā te mea he iti te kohikohinga wera me te kawe hinu.
Hei whakatutuki i ngā tere neke atu i te 2.0 miriona dN, me tautuhi ngā miihini i ngā pūnaha hinu-hau (te iti rawa rānei o te hinu whakahinuhinu). Ka werohia e ngā pūnaha hinu-hau ngā pata hinu iti kua inehia, tika tonu ki te rohe pa o te peera i ngā wā 1 ki te 5 meneti. Mā tēnei ka puta he matotoru kiriata elastohydrodynamic tino pai, me te whakamahi i te hau kōpeke hei whakamatao i te peera me te hanga pēhanga pai hei ārai i te urunga mai o ngā poke.
Ngā Whakatakotoranga, te Rapunga, me ngā Arowhai Whakatutukitanga

Ko ngā wāhanga matua o te whakataurite i te wā o te aromatawai kaiwhakarato ko ngā reiti hapa kua whakaaturia (he maha ngā wā ka taka ngā paearu whāinga ki raro iho i te 50 Ngā Wāhanga Ia Miriona) me ngā tikanga whai. Hei tāpiri, ka taea e ngā wā arahi mō ngā peera pōro whakapā koki tino tika te roa mai i te 12 ki te 16 wiki nā te uaua o ngā tukanga huri me te taurite, e hiahia ana ngā tīma hoko ki te whakatū i ngā whakaaetanga matapae pakari me ngā whakaaetanga haumaru hei ārai i ngā whakararuraru o te raina huihuinga.
Te whakahaere, te rokiroki, te tāutanga, me te whakahaere ratonga
Ka taea te whakangaro tonu i ngā kaha tere o te peera ABEC 7, 9 rānei mā te whakahaere hē. Me tāuta ki roto i te taiao rūma ma, me te tutuki i ngā paerewa ISO Class 7, hei ārai i te poke o ngā matūriki.
Me noho tonu ngā peera i roto i ō rātou takai taketake, hiritia tae noa ki te wā tika o te tāutanga hei ārai i te waikura me te pirau o te waikura i whakamahia e te wheketere. Hei tāpiri, me pupuri tonu e ngā whare rokiroki ngā mana whakahaere āhuarangi tino kaha, me te pupuri i te pāmahana taiao i waenga i te 20°C me te 25°C me te haumākū whanaunga i raro iho i te 60%.
Te Whakaoti i te Whakataunga Kōwhiringa
Ko te kōwhiringa whakamutunga o tētahi peera pōro whakapā koki me whakakotahi i ngā tawhā āhuahanga, te pūtaiao rauemi, me ngā mooni mekameka tuku hei whakatau hangarau kotahi. Me piri pono tēnei wāhanga ki tētahi tukanga aromatawai hanganga hei karo i ngā whakaritenga utu nui rawa atu, i ngā mahi ngoikore rawa rānei.
Te tukanga whiriwhiri taahiraa-i-te-taahiraa
Ka tīmata te tukanga whiriwhiri pūnaha mā te tatau i te uara dN e hiahiatia ana, me te mahere i ngā kawenga hihiri mōrahi. Tuarua, me whiriwhiri e ngā kaihangarau te koki whakapā e whakarato ana i te pakari tuaka e hiahiatia ana, me te kore e neke atu i ngā rohe wera i te tere ūnga.
Tuatoru, ka aromatawaihia te kōwhiringa i waenga i te hanganga maitai katoa me te hanganga uku ranu i runga i te paepae dN me te roa o te ora ngenge e hiahiatia ana. Tuawhā, ka whakaotihia te tikanga whakahinuhinu, ka whakataurite i te māmā o te hinu ki tete āheinga tere-teiteio ngā pūnaha hinu-hau. Hei whakamutunga, ka tautuhia te akomanga tino tika me ngā uara utaina-mua, kia tika ai te hononga o te peera ki ngā manawanui mīhini o te pou me te whare.
Ngā ture whakatau mō ngā tauwhitinga mahi
Ko ngā ture whakatau he maha ngā wā e hiahia ana kia urutau ki ngā taupatupatu mahi me te ōhanga. Hei tauira, mā te tohu i ngā peera uku ranu ka piki ake te utu o te 2.0x ki te 3.0x ki te whakataurite ki ngā peera maitai paerewa. Heoi, ki te whakahaerehia te tono i roto i te taiao whakahinuhinu iti, ka taea e te peera uku ranu te whakaputa i te toru ki te rima ngā wā roa o te roa o te mahi, ka hua ake he iti ake te utu katoa o te mana.
Waihoki, me whakataurite e ngā kaihangarau te kawenga mua me te tere; mā te whakanui ake i te akomanga kawenga mua mai i te 'Māmā' ki te 'Waenga' ka piki ake te pakari o te pūnaha mā te 20% pea, engari i te wā kotahi ka whakaitihia te tere mōrahi e whakaaetia ana mā te 10% ki te 15% nā te pikinga ake o te whakaputanga wera waku. Ko te whakaoti i te kōwhiringa ko te ine i ēnei taupatupatu tuturu ki ngā whāinga matua o te mīhini.
