Te whakamahi i te mātāpono o te tapahi me te whakarewa i te whatu ultrasonic
Te Mātāpono o te Tapahi me te Whakarewa Ultrasonic
Ko te tapahi me te whakarewa ultrasonic tētahi wāhanga iti o ngā tono ultrasonic i roto i te ahumahi, ā, kua piki haere te whakamahinga nā te mea he pai ki te taiao, he whai hua, he ātaahua hoki ki te titiro.
Te kaupapa tapahi me te whakarewa ultrasonic
Mā te tapahi me te whakarewa whatu ultrasonic ka whakamahia te wiri ā-pūkaha auau-teitei o te 20-40kHz, ka whakawhiti i te kaha ki te mata pa o te whatu mā te pane whakarewa. 1. Te Hurihanga Pūngao: Ka hurihia e te pūngao ultrasonic te kaha hiko hei wiri ā-pūkaha auau-teitei, ka whakanuia e te whakawhiti kaha, kātahi ka tukuna ki te pane whakarewa. 2. Te Whakaputa Wera Waku: Ka pēhi te pane whakarewa ki te whatu, ka puta te waku auau-teitei i waenga i ngā muka i roto i te whatu, ka puta tonu ngā pāmahana teitei ā-rohe o te 500-1000℃. 3. Te Whakarewa me te Tapahi Tukutahi: Ka whakarewahia e te pāmahana teitei ngā muka whatu (pērā i te nairona me te polyester), i te mea ka whakakīkīhia e te pēhanga o te pane whakarewa te wāhanga rewa, ka hanga he paparanga whakarewa kaha. Ki te whakamahia me te pane whakarewa mata tapahi motuhake, ka taea e te pāmahana teitei te tapahi i te whatu i te wā kotahi, ka tutuki te "tapahi + whakarewa" whakauru. 4. Te Whakamatao me te Hanga: I muri i te mutunga o te wiri, ka puritia te pēhanga mō te 0.1-0.5 hēkona, ka taea ai te whakamatao me te totoka o te wāhi whakarewa, ka oti te tukanga tapahi me te whakarewa. (Ka whakaratohia e ngā pūnaha hau he whakamarumaru, ka whakarite hoki i te whakamatao me te hanga i te wā e tapahi ana me te whakarewa.)
Te hanganga o te pūnaha tapahi me te whakarewa ultrasonic
Ko te pūnaha whakarewa kirihou ultrasonic e whakamahia whānuitia ana he toru ngā wāhanga matua: he whakaputa hiko ultrasonic (pouaka hiko), he pūwhakawhiti ultrasonic (wiriwiri), me he pokepokea ultrasonic (upoko pokepokea, upoko whakarewa, haona).
Pūhiko whakaputa-oro (pouaka hiko) Ngā whakawhiti-oro (ngā wiri), ngā pokepokea ai-oro (ngā pane pokepokea ai, ngā pane whakarewa, ngā haona)
1. Pūhiko hiko-orooro (pouaka hiko): Ka huri i te hiko matua hei putanga auau-tiketike, ngaohiko-tiketike pumau.
2. Pūwhakawhiti orooro (whakakorikori): He taputapu oro e huri ana i te pūngao, e whakaputa ana i te pūngao hiko hei pūngao miihini.
3. Whakakaha: Ka whakarerekētia te kaha o te wiri ā-pūkaha o te transducer mā te whakamahi i tētahi ōwehenga whakanui kua hoahoatia i mua.
4. Ngā pokepoke (ngā pane whakarewa, ngā haona): Kua whakaritea ki ngā rahinga motuhake e ai ki ngā hiahia o ngā mahi whakarewa me te tapahi, ā, kua hangaia me ngā āhuatanga oro hei whakatutuki i ngā whakaritenga orooro o te pūnaha ultrasonic. Kei raro nei, ka whakamahia e au ētahi tātai hei whakamārama i te āhuatanga whakatikatika tawhā i roto i ngā mahi.
Pūngao = Te Whānui * Te Pēhanga * Te Wā * Te Pūmau K = Te Mana * Te Wā
E whakaatu ana ngā tātai i runga ake nei, i roto i te whakarewa me te tapahi, ko te kaha o te ngaru ultrasonic (ka taea te whakatakoto ki runga i te whakaputa hiko), te pēhanga (te pēhanga hau, te taipana rango hiko rānei, tae atu ki te pakari me te mārō o te hanganga), me te wā tukunga ngaru he hononga pai ki te pānga whakarewa me te tapahi. Arā, ki te kore e tapahia pai te hua, ka taea te whakarite pai i ēnei tawhā. Ko te tikanga o tēnei, ko te teitei ake o ēnei tawhā, ko te pai ake? Kāore rawa!
P = K∗A∗f∗δ, ko P te tohu o te mana whakarewa, i roto i te W;
K he pūmau e pā ana tōna rahi ki te kawe oro me te tohatoha pūngao o te rauemi. Ko te tikanga o tēnei, e kīia ana e tātou he rerekē ngā tawhā e hiahiatia ana mō ngā rauemi rerekē kia tutuki ai ngā whakaritenga.
He e tohu ana i te horahanga o te tapahi whakarewa, e inehia ana i roto i ngā mita pūrua (㎡). Koinei te mata pa o te tapahi whakarewa, nō reira ko te roa me te koki o te mata tapahi te tikanga e whakatau ana i tēnei horahanga.
wh ko te auau ultrasonic, ko te tikanga, i roto i te ariā, he māmā ake te whakarewa i ngā auau teitei ake. Heoi, i roto i te oro, ko te teitei ake o te auau, ko te uaua ake o te whakatutuki i te kaha nui; ko te waeine ko Hz.
rā e tohu ana i te kaha, e inehia ana i roto i ngā mita (m). I roto i te ariā, he pai ake te whakarewa me te tapahi i te kaha nui ake. Heoi, ko te roa o te ora ngenge o ngā rauemi whakarewa e pā ana ki te auau, ngā āhuatanga o te rauemi, te ahotea, te wā, te pēhanga, me te pakeke, ā, nō reira ka pāngia e ētahi atu tawhā.
E ono ngā āhuatanga e pā ana ki ngā hua tapahi me te whakarewa ultrasonic:
Pēhanga + Wā + Hanganga Mīhini + Rauemi Hua + Patuiro
1. Te pēhanga whakarewa orooro
Mā te pēhanga tika ki te mata whakarewa ka huri te rauemi whakarewa mai i te pīngore ki te kirihou, ka whakatairanga i te horapa o ngā ngota ngota, ka nekehia hoki te hau toenga mai i te whakarewa, ā, ka piki ake te mahi hiri o te mata whakarewa. Ko te tikanga, kāore te pēhanga e neke ake i te 0.5 MPa.
2. Wā whakarewa/tapahi orooro (wā tukunga ngaru)
He mea nui te wā rewa tika me te wā whakamatao rawaka. Mēnā he wera pumau te putanga, ka kore e oti te whakarewa i te wā iti, engari ka puta te whakarerekētanga o te whakarewa i te wā roa, ka pupū ake te paru, ā, i ētahi wā ka puta he wāhi wera (te rerekētanga o te tae) i ngā wāhi kāore i whakarewahia. He mea nui kia tino mimiti te mata whakarewa i te wera kia tae atu ki te āhua rewa katoa hei whakarite kia tika te horapa me te hanumitanga o ngā ngota ngota. I te wā kotahi, me nui te wā whakamatao kia eke ai te whakarewa ki te kaha e tika ana.
3. Te kaha o te orooro
4. Hanganga mīhini
Ka pā tika te tika me te pumau o te hanganga anga ki te pānga whakarewa, inā koa mō ētahi hua tika, ina koa me ōrite te hanganga mīhini ki te tika o te hua.
5. Ngā Rauemi Hua
Ko ngā āhuatanga pēnei i te rauemi o ngā wāhanga i whakarewaina, tōna hanganga, te matotoru, me te ātete ki te pēhanga ka pā tika ki te pānga whakarewa.
6. Te whakatikatika i ngā taputapu
Hei whakamutunga, kia tutuki ai i tētahi hua ngā hua tapahi me te whakarewa ultrasonic pai rawa atu, he mea nui anō hoki te rapu i ngā taputapu hei whakatika i ngā hapa. He mea nui te whakataurite ngāwari me te whakarerekētanga o ngā tawhā me te rapu i ngā hapa i te wāhi e ngā miihini.
