Kupu Whakataki

Neke atu i te 240 tau te whatu whenu hei tūāpapa mō te hangarau kakahu, e whanake ana mā roto i te miihini tika me te auahatanga rauemi tonu. I te tipu haere o te hiahia o te ao mō ngā kakahu whatu whenu kounga teitei, ka piki haere te pēhanga ki ngā kaihanga kia whakapiki ake i te hua me te kore e whakararu i te tika, i te kounga rānei o te kakahu. Ko tētahi wero nui kei roto i te ngākau o te mīhini whatu whenu—te tikanga nekehanga whakawhiti tere-tere o te heru.

I roto i ngā mīhini whatu miro tere-teitei o ēnei rā, ka tere te nekehanga taha o te heru e tika ana mō te hanganga papanga. Heoi, ina neke atu te tere o te mīhini i te 3,000 hurihanga ia meneti (rpm), ka kaha ake ngā wiri whakawhiti, te haruru miihini, me ngā taumata haruru. Ka whakararu ēnei āhuatanga i te tika o te tūnga o te heru, ā, ka piki ake te tūponotanga o te tukinga ngira, te whati miro, me te heke o te kounga papanga.

Hei whakatutuki i ēnei wero hangarau, kua arotahi ngā rangahau hou ki te tātari wiri, te whakatauira hihiri, me ngā tikanga whakatauira matatau hei arotau i te nekehanga o te heru. E tūhuratia ana e tēnei tuhinga ngā whanaketanga hangarau hou, ngā tono mahi, me ngā ahunga whakamua o te whakahaere wiri whakawhiti o te heru, e whakaatu ana i te whakapau kaha o te umanga ki te hangarau tika me ngā otinga pumau, mahi-teitei.

Ngā Whakatairanga Hangarau i roto i te Whakahaere Wiri o te Heru

1. Te Whakatauira Hihiri o te Pūnaha Heru

Ko te kaupapa matua o te arotau i te mahi a te heru ko te mārama tika ki tōna whanonga hihiri. Ko te nekehanga whakarara o te heru, e peia ana e ngā kaiwhakaoho hiko, e whai ana i tētahi tauira huringa e whakakotahi ana i te nekehanga taha me te wiri. I te wā e mahi ana i te tere teitei, me āta whakahaere tēnei nekehanga huringa kia kore ai e nui rawa ngā wiri me ngā hapa tūnga.

I whakawhanakehia e ngā kairangahau tētahi tauira hihiri ngāwari, kotahi te nekehanga o te herekoretanga e aro ana ki te nekehanga taha o te heru. E whakaarohia ana e te tauira te huihuinga heru, ngā ara ārahi, me ngā wāhanga hono hei pūnaha whakamātao puna, e wehe ana i ngā mea matua e pā ana ki te wiri. Mā te tātari i te papatipu, te pakari, ngā tauwehenga whakamātao, me ngā kaha whakaoho o waho mai i te motuka servo, ka taea e ngā kaihangarau te matapae i ngā urupare tauwhiro me te āhua pumau o te pūnaha me te tino tika.

Mā tēnei tūāpapa ariā ka taea te whakamahi i tētahi huarahi pūnaha ki te whakahaere i te wiri, hei ārahi i ngā whakapainga hoahoa me te arotau i te mahi.

2. Te Tāutu i ngā Pūtake Wiri me ngā Mōrearea o te Āhuatanga

Ko ngā wiri whakawhiti te take matua o te nekehanga tere o te heru i te wā e hangaia ana te papanga. Ka puta mai ngā kaha whakawhiti i ia huringa ahunga, ka whakanuia e te tere o te mīhini me te papatipu o te heru. I te pikinga o ngā tere o te mīhini ki te whakatutuki i ngā whāinga whakaputa, ka piki ake te auau o ēnei kaha, ka piki ake te mōrearea o te haruru - he āhuatanga e ōrite ana te auau whakaoho o waho ki te auau tūturu o te pūnaha, ka hua ake ngā wiri kāore e taea te whakahaere me ngā hapa miihini.

Mā te tātaritanga aratau mā te whakamahi i ngā taputapu whakatauira ANSYS Workbench, i tautuhia e ngā kairangahau ngā auau tūturu nui i roto i te hanganga heru. Hei tauira, i tatauhia te auau tūturu tuawhā i te 24 Hz pea, e rite ana ki te tere mīhini o te 1,450 rpm. Kei roto i tēnei awhe auau he rohe mōrearea oro, me āta whakahaere i ngā tere mahi kia kore ai e kore pumau.

Mā tēnei mahere auau tika ka taea e ngā kaihanga te hanga otinga hei whakaiti i te haruru me te tiaki i te roa o te wā o te mīhini.

3. Ngā Mahi Whakaiti i te Wiri Hangarau

He maha ngā otinga hangarau kua whakaarohia, kua whakamanahia hoki hei whakaiti i ngā wiri whakawhiti i roto i te pūnaha heru:

• Te karo i te haruru:Mā te whakarerekē i te hanganga rauemi o te heru, te tohatoha papatipu, me te pakari o te hanganga ka taea te neke i ngā auau taiao ki waho i ngā awhe mahi noa. Me whakataurite te roa me te whai huatanga o te pūnaha ki tēnei huarahi.
• Wehewehenga Wiri Kaha:Mā ngā whakairinga mōtini kua whakapakaritia me ngā hoahoa tīwiri pōro kua arotauhia ka whakarei ake i te wehewehe wiri. Mā te tika o te tuku pai ake ka maeneene ake te nekehanga o te heru, inā koa i ngā huringa tere o te ahunga.
• Whakaurunga Whakamarumaru:Ka pehia e ngā puna whakahoki me ngā wāhanga whakaiti i runga i te reriwe arataki ngā wiri moroiti, ka whakau i te heru i ngā wā "mutu-tīmata".
• Ngā Kōtaha Whakauru Kaha Puku kua Arotauhia:Mā ngā kōtaha whakauru matatau pērā i te whakaterenga sinusoidal ka whakaitihia ngā ru miihini me te whakarite kia maeneene ngā pihi nekehanga, ka whakaitihia hoki ngā mōrearea tukinga ngira.

Ngā tono i roto i te ahumahi

Mā te whakaurunga o ēnei hangarau whakahaere wiri ka puta he hua kitea puta noa i ngā mahi whatu miro tino mahi:

• Te Kounga Kakahu Whakapai Ake:Mā te whakahaere tika o te heru ka rite te hanganga o ngā koropiko, ka whakaitihia ngā hapa, ka whakarei ake hoki i te ataahua o te hua.
• Te Tere o te Mīhini me te Pūmautanga:Mā te karo i te haruru me te urupare hihiri kua arotauhia ka taea te whakahaere haumaru, tere hoki, ka whakapiki ake i te hua.
• Te Whakaiti i te Tiaki me te Wā Whakamutu:Ka roa ake te roa o te ora o ngā wāhanga me te whakaiti i ngā hapa miihini mā te wiri whakahaere.
• Ngā Mahi Whai Hua Pūngao:Mā te nekehanga maeneene, pai o te heru ka whakaiti i te ngaronga pūngao, ka whakapai ake hoki i te whai huatanga o te pūnaha.

Ngā Auahatanga o te Ao me te Tirohanga ki te Ahumahi

Ko te whanaketanga o te hoahoa mīhini whatu whenu e hangai ana ki ngā au o te ao e aro ana ki te aunoatanga, te mamati, me te pumau. Ko ngā huarahi matua e puta ake ana ko:

• Aroturukitanga Wiri Maamaa:Mā ngā whatunga pūoko wā-tūturu me ngā tātaritanga matapae ka taea te tiaki matatau me te arotau i te mahi.
• Ngā Rauemi Matatau:Mā ngā rauemi hiato mama, kaha hoki e whakanui ake te tere o te mīhini, me te pupuri tonu i te pumau.
• Hangarau Mahanga Mamati:Ka whaiwhakaahua ngā tauira mariko i ngā urupare hihiri, kia taea ai te kite wawe i ngā take wiri i ngā wā hoahoa.
• Hoahoa Mīhini Tauwhiro:Ka whakaitihia e te mana wiri ngā tukunga haruru me te kakahu miihini, ka tautoko i ngā mahi e whai hua ana ki te pūngao me te taiao.
