pūrākau pdc mo te koha

Nō te whiwhinga PDC (Polycrystalline Diamond Compact) he tātai hoko e whakamana ana i ngā hanganga herehere whakatūru rēhita hei whakamahi mō ētahi atu matatika mahi. Ko ēnei tātai hanga kuhu e whai ake nei i ngā tohu herehere kimihau e whakauru ana ki te tinana tungsten carbide, ka hangaia hei whakapakari i te noho i roto i ngā wāhi kuhu nui. Ka hangaia ngā tātai i te hunga herehere o te ao hei whakatakoto pai rawa i ngā tohu me te pai o te pūnaha hīrau. E ai ki ngā momo rahi e taea ana, e whai mai ana i te 4 ki te 28 pouaka i te uiui, ka hangaia ngā tātai kia taea ai ngā hiahia kuhu rerekē mō ngā whenua rerekē. Hei tā ngā tātai PDC, kei raro i ngā whakawai hanga paihere, pērā i te whakatika i te āhua o ngā tohu, te whakarite paihere o ngā mata, me ngā momo hanga matua e whai ana ki te whakapai i te noho kuhu me te roa o te tātai. Ka hangaia hei whakamahere pai i te haerenga i te mahi, hei whakaiti i ngā whiuwheowheo, me te whakamana paihere i te tahuri o te huringa. Kei raro i ngā tohu whakaaeae tōmua e whai ana ki te whakatika pai i te whakawhiti i te kuhu me te whakamahana i te mahi, me te whakatūpū pai o te tataki ka taea e ia te whakarite i ngā paetūnga nui me ngā waehu o te waimārama. Nō reira, kei te whai take ēnei tātai hei whakamahi i ngā kaupapa rangahau oi me te raranga, me ngā kaupapa kuhu geothermal, kei reira tonu ka whakamana i te rahi o te kuhu me te roa o te tātai.

Te Whakauru i te Teka Diamond Matua

Te Whakauru i te Teka Diamond Matua

Kei ngā pūtē PDC hei hoko e whakaatu ana i te whaihanga matua o te tekau mā rima diamond, e whakatū mai ana i ngā ture hou ki te whakahaere i ngā paihere kawe. Ki ia pūtē, he whiriwhiri ā-waho i ngā kutu diamond whakaputurua, e hanga nei i waenga o ngā take tohu hei whakamahere i te whero matua me te haere wera tūpato. E tuhi nei ngā kutu diamond i runga i ngā papa tungsten carbide me te hunga whakangungu matua, e whakatupu ana i te hononga korekore e paheko ana i ngā tikanga whakatetonga nui. Kia puta ai tēnei mahi whakauru matua ki te whiuwhiu paihere matua me te paihere kutu e rua. Ka noho ngā kutu diamond i ō rātau parauri whakawehewehe moe roa tonu i te kitea i te pūtē matua, e whakamana ana i te paihere kaingāngaru mō te ao o te pūtē. Kei roto hoki i te tekau mā rima, he whakauru ā-mata ki ngā momo whakarite mata e whakapai ana i ngā whenu matua o te diamond, e whakapai ake ana i tana whiuwhiu ki te whakapae me te whiuwhiu whakateretere.
Te Tūranga Whakangungu Hīraumi

Te Tūranga Whakangungu Hīraumi

He mātāpono nui o ēnei PDC pūoro he rautaki hīrau matatini kua hangaia hei whakapai i te taurite me te roa o te pūoro. Ko te rautaki ka whakauru i ngā puhipuhi e tika ana, e hanga nei ngā matawhāiti hīrau pai rawa, e awhina ana ki te whakamahana pai o ngā kāterekareka me te whakatiki pai i te tahutahu o ngā mate pūoro. Ko te rautaki hīrau ka whakauru hoki i ngā momo whakataurite matatini hei whakapai i te whakawehenga hīrau mō te kanohi pūoro. Ko tēnei ka puta mai i te waihanga pai o te kawe hīrau me te whakahē i te kōpaki pūoro, ā, ka whakaiti i te korenga pūoro, inaianei i ngā whenua kikino. Ka tiakina e te rautaki hīrau tēnei te whakarereke tahuhu iho pai, he mea nui tēnā hei whakapai i ngā ratonga tuhinga i runga i te roa o te pūoro me te whakapakari i te oranga o te pūoro. Ka whakaiti hoki te rautaki hīrau pai i te whakakore i te kanonau o te tinana pūoro me ngā momo matua, ka whakaheke ki te whaiwāhi o te rautahi.
Whakahaere Whakahaere Raraunga Tirohanga

Whakahaere Whakahaere Raraunga Tirohanga

Kei te whai ngā pūtahi PDC mo te koha ko ngā whakahaere rautaki taea rawa, e taea ana ki te whakatika i ngā take whakamahere kōrowhiti me ngā whenua. Ki te whiuwia tēnei wanaunga, ka taea e ngā whakahaere whakamahere kōrowhiti te tirotiro i te rautaki pūtahi e tika ana mo ō rātou hiahia īwa. Ko ngā take taea rawa hei whakatika, ko ngā taararau totohu, ko ngā mata o ngā totohu, me ngā wheako tuara, e āheinga ana kia puta ai te mahi kōrowhiti pai rawa i waenganui i ngā momo whenua. Ko te tino taea rawa hei whakatika heoi anō ki te whakahaere rautaki wai, e taea ana te whakarerekē i ngā taararau nozzles me te whakapae kia whai ai ki ngā āhuatanga pūreko. Kia whai ake tēnei ngenetanga, ka taea e ngā whakahaere te whakaū i ō rātou mahi kōrowhiti ahakoa iti ai ngā utu mahi, mā te whakarite pai i te rautaki pūtahi ki ngā hiahia whakamahi.
