Nā ʻāpana PDC no ka ʻeli lanahu a me ka hana pōhaku (3-ʻēheu)
He mea paʻakikī loa ka ʻōpuʻu wili PDC i hui pū ʻia me ka daimana a me ka hui paʻakikī ma lalo o ke ana wela kiʻekiʻe. ʻAʻole wale ia he mau pono o ka paʻakikī a me ke kūpaʻa mai ka daimana, akā he mau pono nō hoʻi o ke kūpaʻa kiʻekiʻe a me ka pahi nui mai ka hui paʻakikī. Hoʻomaikaʻi nui wau i ka pono o ka wili ʻana a ʻo ia ka ʻōpuʻu wili kūpono no ka hana wili o ka pōhaku waena a paʻakikī a me ka pōhaku paʻakikī loa.
Hoʻoheheʻe ʻia a paʻi ʻia ka mea lawe o nā ʻāpana PDC e ke kila papa mua. Hoʻoikaika ʻia kona hiki mechanical e nā lako hana hoʻomehana vacuum piha piha.
Hoʻohana ke ʻano maʻamau i ka PDC Kina ma ke ʻano he pahi, ʻoiai ʻo ke ʻano ikaika loa e hoʻohana i ka pahi ʻAmelika na GE. ʻO ke koho ʻana i ke ʻano kūpono e hana i ka lakio kiʻekiʻe o ka hana a me ke kumukūʻai.
Hoʻohana nui ʻia kā mākou mau ʻāpana wili PDC ma nā ʻoihana āpau, e like me ke kālai lanahu, ka ʻimi ʻaila, ka ʻimi honua, ka wai a me ka hydroelectric, ke alahao a me ke alanui, ke kūkulu ʻana i nā tunneling a pēlā aku.
Hoʻopili ʻia nā ʻāpana heleuma PDC ʻelua ʻēheu (ʻano maʻamau semi-puni) i ka paʻakikī ʻaʻole i ʻoi aku ma mua o f8. ʻO ke ola hana he 10-30 mau manawa o nā ʻāpana alloy maʻamau, a hiki ke hoʻomaikaʻi ʻia ka pono ma 60%. Eia kekahi, ʻaʻole pono nā ʻāpana PDC i ka helu ʻana, kahi e hoʻohaʻahaʻa ai i ka ikaika o ka hana a kōkua i ka mālama ʻana i ke kumukūʻai.
ʻO GE, ka hui ʻAmelika, e hana ana i ka mea nui o ka pahi no nā ʻāpana heleuma PDC ʻelua ʻēheu (ʻano hoʻoikaika semi round). ʻO ka nui o ke daimana he 1.5 mau manawa o nā ʻāpana maʻamau, nona ke kūpaʻa abrasive maikaʻi loa a hoʻopili ʻia i ka pōhaku waena a me ka paʻakikī (f <12).
Hoʻohana nā ʻāpana PDC i hoʻoikaika nui ʻia i nā daimana ʻano pōpō hou i hoʻolālā ʻia i kāna pahi. Nā hiʻohiʻona: wikiwiki o ka ʻeli ʻana, kūpaʻa hopena kiʻekiʻe.
Ke hana nā ʻāpana wili, hoʻohana ʻia ka lihi e ʻoki i ke ʻano maʻamau a like, ʻoiai ʻo ka lihi e hana ma ke ʻano he pale e pale aku ai i ka nui o ka wili ʻana, kahi e kōkua ai i ka hoʻohaʻahaʻa ʻana i ka hiki ke hōʻino ʻia. Mahalo i kēlā, ua hoʻomaikaʻi ʻia ka pae wili paʻakikī.
