Pūwero Korehau Uku Matatau
Pūwero Korehau UkuHe tūāpapa pikau-kawe e whakamahi ana i te kaupapa o te mimiti korehau hei whakau i ngā wahi mahi. Ko te wāhanga o te pūwero korehau e tuku ana i te korehau he pereti uku poro. Ka huihuia te pereti uku poro ki roto i te kōhao totohu o te turanga, ā, ka herea tōna taha, ka hiritia ki te turanga. He mea hanga te turanga ki ngā rauemi uku, ki ngā rauemi konganuku rānei tino tika. Mā te whakakotahi i te turanga whakarewa, uku rānei ki tētahi uku poro motuhake, ka taea e te hoahoa o te ara hau ā-roto tino tika te piri maeneene me te pumau o te wahi mahi ki te kapu momi korehau ina pāngia e te pēhanga kino.
Nā te mea he tino angiangi ngā pūwero o ngā uku pūwero, ka taea te piri o te mata o te mea mahi ki te kapu momi korehau me te kore he āhuatanga kino pērā i ngā karawarawa, ngā pokapoka rānei i puta mai i te pēhanga kino.
Ngā Āhuatanga o te Porous Ceramic Vacuum Chuck:
① Hanganga mātotoru, ōrite hoki: Ātete ki te mimiti paura silicon/para huri, he ngāwari ki te horoi.
② Kaha rawa, ātete ki te kakahu: Kāore e rerekē te āhua i te wā e huri ana, ka whakaiti i te pakaru/te pakaru o te taha.
③ Roa te ora: He tino pai te pupuri i te āhua o te mata, he roa te huringa whakakakahu me te iti o te tango.
④ Teitei o te whakamarumaru: Ka whakakore i te hiko pateko.
⑤ Ka taea te whakamahi anō, he ngāwari ki te whakakakahu: Kāore e pakaru/marara i te wā e whakahou ana, ka taea te whakamahi anō i ngā wā maha.
⑥ Kāore e puehu, ā, pumau: Kua whakakā katoatia, kāore he tukunga matūriki.
⑦ Māmā: Ka whakaitihia te taumaha e te hanganga pūwero.
⑧ Ātete matū: Ka taea te whakarite mō ngā taiao waikura mā te whakahaere rauemi/tukanga.
Te Pūwero Korehau Uku VS Te Kapu Momi Whakarewa Tuku Iho:
Pūwero korehau uku i roto i te mara haurua-ira
He taputapu whakapiri me te kawe ngā pūwero uku i roto i te hanga papa whakarewa haurua-haurua. He papatahi me te whakarara te āhua, he hanganga matotoru, he ōrite te āhua, he kaha te uruhanga o te hau, he kaha mimiti ōrite, ā, he ngāwari te whakakakahu. Nā ēnei āhuatanga ka pai mō ngā tukanga hanga papa whakarewa haurua-haurua pērā i te whakaangawari, te tapatapahi, te huri, te horoi, me te whakahaere. Ka aro pai rātou ki ngā wero pēnei i te tānga papa whakarewa, te pakaru hiko o ngā maramara, me te poke o ngā matūriki, ka tutuki ai te kounga tukatuka tino teitei mō ngā papa whakarewa haurua-haurua i roto i ngā tono mahi.
