Te pūtahi PDC (Polycrystalline Diamond Compact) he whakamātau hou hoki nui i te hunga mōhiohere here me te mātauranga matū. Ko tēnei rautaki whakamātau matua e āheinga ana i ngā kaiwhakahatutia kahurangi, ka tīmata ki runga i te tinana kōwhai hei whakapiki i ngā whenua rite tonu. Hei tūtohu mo ngā wāhanga o te pūtahi nei, ko ngā kaiwhakahatutia e mahia ana i te diamona, ko ngā diamona polikarihana e hono nei ki ngā tūmau tungsten carbide, me te whakatū mai i ngā wāhanga whakahatutia nui rawa atu. Ka whakarereke ngā āhua nei ki runga i te kāwā o te pūtahi hei whakapai i te hohourongo whakahatutia me te whakamātau o te tirohanga i roto i te mahi. Ko te hanga o te pūtahi e āhei ana i ngā hīrahi tūponotia hei whakatakoto i ngā waiporoporo kia pai ai te whakatika me te whakawehenga i ngā kaiwhakahatutia i te wā e whakamātau ana. Ko te mea e whakaheke ana i te PDC pūtahi ko tana take e āhei ana ki te whakamātau mutunga kore ki tua noa i te hiahia mō ngā whakarerekē pūtahi, e whakaiti ana i te wā korenga i te mahi. Ko te hanga matua o te rautaki e āhei ana i te tirotiro whakahaere me te whakatūpū whanaketanga, e whakamahia ana hei whakapai i te oranga pūtahi e hirahira ana me te kawe pai ake i ngā mahi whakamātau i waenganui i ngā āhuatanga whenua rerekē. Nō te wā e āhei ana ngā PDC pūtahi hou ki te whakauru i ngā āhuatanga matua hou, pēnei i ngā āhua kaiwhakahatutia motuhake me ngā hanganga karu whakapai, ka whakapai i ngā ratonga whakakokiri me te whakamana pai tonu i te tirohanga.

Ngā upoko PDC whakaritenga pai noa i ngā tūmomo tono

Nā ngā pūtake PDC e whai ake ana i te maha o ngā hiranga pai, ka hiki i a rātou hei whakaae matua mō ngā mahi herehere. Tuatahitia, ko ngā pūtake nei e tukuna ana i te pai mea herehere, e taea ana te whanonga āwhina nui atu i ngā pūtake kōhatu herehere o mua, e hoki mai ana i te wā me te moni. Kāore he hiahia ki ngā kōwhiri ā-tae i runga i ngā pūtake PDC, e whai ana i te mahi herehere tino mārongo, e iti ana i ngā whiuwhiu, e noho ake ana i te oranga o te pūtaki me ngā whare herehere. Ko te pai tino whai ake o ngā pūtake e whai ana i te roa o te mahi, e iti ana i te waenga o ngā wa kaiwawao hei whakarere i ngā pūtake kēhua. He mea nui tēnei i ngā mahi herehere roa, kei reira te whakarerekē o te whakarite pūtake, e nui ana te utu me te wā. E āhei ana ngā pūtake ki te whakaatu i te mōhiohio mō ngā momo whenua e rahi ana, mai i ngā whenua mēngi ki ngā whenua porowhita, me te pai rawa ki ngā mahi herehere rerekē. Ko te whakaahuatanga hīrahi e tiakina ana ngā kaiwhakaawe me te tiakina pai o te pūtake, e whakamutu ana i te kaiwhakaawe pūtake, me te wehewehe pai o te whakahaere. E tuku ana ngā pūtake i te whakahaere pai o te tirohanga, e hiahia ana ki te tika o te pūnaha pūtake i ngā mahi herehere tirohanga. Kāore he wā moe i runga i ngā pūtake PDC, e iti ana i te hoko o ngā whawhapono mehana, me te waihangatanga o ngā huarahi whakahaere. Nā te āhei hoki o ngā pūtake ki te tiakina i te paetaha mā roto i te wā o te mahi, ka tiakina pai ai te pai o te poaka, ka whakamahia ai ngā mahi whakatū wā kē. Ko te mōhiohio hīrahi o ngā pūtake PDC e hoki mai ana i te iti o ngā hiahia toru, me te iti hoki o te kaiwhakahaere motuhake moni i roto i ngā mahi herehere.

Takanga Pūhanga Matatū

Kei te whakapakari ngā rautaki kōpūtahi o te PDC bit i te hīkoi matua whakamua i te whirinaki i ngā momo whakatere. Nā te whakamahi pūmau i ngā kaiwhakahewhiti polycrystalline diamond compact he anga tuatahi tēnei. E hanga ana ngā kaiwhakahewhiti diamangihia nei i raro i ngā wāhi wehe me te wehenga āhuarangi, e hia tonu ana te toka me te mōhio ki te kore tangata. I whakatakoto ngā kaiwhakahewhiti i runga i te tinana o te bit me te hunga whakapakari tino matua hei whakamana i te whakapiri haumaru, ahakoa ngā take whakatere nui. Ki ngā wāhi tika, ka whakatakotoria inaianei ngā kaiwhakahewhiti hei whakapai i te mahi kaiwhakahewhiti, ā, hei tirotiro hoki i te kore tangata. Kei te hanga i te rautaki kaiwhakahewhiti i ngā whatitanga kaiwhakahewhiti rerekē me ngā taunga kaiwhakahewhiti e mahi ana tahi hei whakatupu i te mahi whakatere pai mō te kape kitea katoa. Ko tenei whakahaere mōhiko e whiwhi ana i te whakawhitinga pai rawa o ngā kaiwhakatere me te whakamana hoki i ngā patapata wehe, e whakapuakitia ana i te wā o te mahi.
Whakamahinga Hīra

Whakamahinga Hīra

Te rākau ā-maihi o ngā pūtē PDC he tauira hōu o te mātauranga hanganga i te whakahaere i ngā wai whakamahi. Kua hangaia te whiuwhiuinga nozzles ki te mātauranga ā-tinana i runga i ngā whakaritenga matatini hei hīkina i te kuhu pai rawa o te wai ki runga i te kanohi o te pūtē. Ka taea e tēnei hanganga ā-maihi pai rawa te tahutahu i ngā kaihanga mai i te taha raro o te poaka me te whakahē i te whakapakari kaihanga e āheinga ana i te whakamārama i te mahi whakamahi. Ki te tika, ka hangaia ngā nozzles ki te tūranga pai hei hokiwhiti i ngā toanga wai ki te torotoro i ngā kaihanga me te whakawehi i te whakahaere i te whakamahi i te wā. Hei tā te hanganga ā-maihi, ka whakauru hoki i ngā whakaaetanga hei whakahē i te pūtake mai i ngā whenua kikino ki te tae ki ngā konaki whiuwhiu me te kuhu pai rawa o ngā rahi wai hei whakakaha i te whakamahi. Ka whai huihui anō tēnei whakarite ki ngā ara wai i roto i te pūtē, ka hangaia hei whakaiti i ngā mate paoro me te whakamana i ngā rahi wai pai rawa hei whakamahi pai i te tahutahu.
Whakamātau Whenua

Whakamātau Whenua

Nā ngā pūtanga PDC te whakaatu i tō rātou mōhiotanga nui ki te mahi i runga i ngā momo hangarua e rerekē ana, nā runga i ō rātou āhuatanga hanga hei whakarite. Kua hangaia te rākau kiriata o te pūtanga kia whiwhi kaha i ngā putanga hangarua, me te whakamana i te huarahi pai o te horomataki i waenganui i ngā whakawhiti. Ko tēnei mōhiotanga ka whai wāhi i ngā tuhinga matihiko e whakauru nei i te wehenga i waenganui i te whiu me te haere pai. Nā ngā pūnaha matihiko e whakamahia ana ki te hanga o te pūtanga ka taea te whakarite i te wehenga i ngā āhuatanga hangarua, me te whakamana hoki i te whakatika pai o te pūtanga. Hei tirohanga, ko ngā whenua matapaki e whakamahia ana ki te hanga o te pūtanga kei te whakamana i te whiu e pa ana, ahakoa te whakamana i te whakaaeke i ngā hangarua whakahē. Ko te wāhitirite o te pūtanga ka hangaia me te mōhio nui ki te whakatutuki me te whakamana, kia tiakina ai te pai o te pūtanga whare i waenganui i te mahi horomataki.
