PDC Bit
Hiʻona o PDC bit
1, He kūpono no ka wili ʻana i ke ʻano o ka paʻakikī.
2, Hoʻolālā i ka hoʻolālā ʻoki ʻoki asymmetrical a me ka haʻahaʻa haʻahaʻa i hiki ke pale ʻia ka puʻupuʻu.
3, ʻO ka pale ʻana i ka gauge composite a me ka hoʻolālā torque haʻahaʻa e hoʻomaikaʻi i ka helu o ke komo ʻana.
4, ʻO ka hoʻolālā kaulike hydraulic CFD ka hopena i ka hoʻomaʻemaʻe ʻana a me ka ʻoki ʻoki ʻana.
5, ʻO ka hoʻohana pū ʻana i nā compact PDC hana kiʻekiʻe e hoʻolōʻihi i ke ola bit
6, ʻO nā helu nozzle kiʻekiʻe a / a i ʻole nā awa paʻa e lawelawe maikaʻi loa i ka hoʻomaʻemaʻe, hoʻoluʻu a me nā ʻoki ʻoki.koi menā kahe hydraulic loaʻa. Hāʻawi i nā kahe kahe kiʻekiʻe me ka liʻiliʻi o ka piʻi ʻana o ke kaomi pā.
Hiʻona: Hoʻopili ʻia nā daimana i loko o ka matrix ma hope o nā mea ʻoki PDC
Pōmaikaʻi: Hoʻonui ʻia nā kiʻi i wili ʻia i nā noi abrasive
