He aha ka ʻokoʻa ma waena o ke kino kila a me ka matrix body PDC bit

Hana nui ʻia ka ʻāpana wili PDC e nā mea ʻoki PDC a me ke kila, me ka hoʻohui ʻana i ka paʻakikī maikaʻi o ke kila a me ke kūpaʻa ʻana o ka polycrystalline diamond compact e hana ai i ka ʻāpana PDC i ka wikiwiki o ke kaʻina hana wili. ʻOi aku ka wikiwiki o ka wikiwiki o ka ʻāpana kila PDC i ka hoʻokumu palupalu ʻoiai ʻoi aku ka pale ʻana o ka matrix body PDC bit, hiki i ka matrix body bit ke wili i ka hoʻokumu paʻakikī ke hoʻohālikelike ʻia me ka ʻāpana kila PDC bit ma muli o kona kino matrix tungsten carbide, akā he lohi kona kiʻi ke hoʻohālikelike ʻia me ka ʻāpana kila PDC drill bit. Inā makemake ʻoe i kekahi o nā ʻāpana PDC, e ʻoluʻolu e kelepona iā Far Eastern Drilling.

Nā ʻāpana PDC Kino Matrix vs. Nā ʻāpana PDC Kino Kila

Inā ua hana ʻoe i ka ʻeli ʻana no kekahi manawa, ua lohe paha ʻoe e pili ana i nā ʻāpana PDC. ʻO PDC ke kū nei no "polycrystalline diamond compact," ʻo ia hoʻi ka mea i hui ʻia e hana ai i ka ʻili ʻoki o kēia mau ʻāpana. Hana ʻia ʻo Matrix Body PDC a me Steel Body PDC me kēia hui.

He nui nā inoa o kēia mau ʻāpana. Ua kapa pinepine ʻia lākou:

• Nā ʻāpana PDC
• Nā ʻāpana liʻiliʻi daimana polycrystalline
• Nā ʻāpana niho ʻāpana composite
• Nā ʻāpana ʻoki daimana polycrystalline

Hoʻohana pinepine ʻia nā ʻāpana PDC no ka ʻeli ʻana i ka ʻaila - akā kaulana nō hoʻi i nā ʻoihana ʻē aʻe. Ua hana ʻia lākou i ka makahiki 1976 a ua kaulana like lākou i kēia manawa menā ʻāpana wili-kono(ke ʻano o ka ʻāpana me nā ʻāpana e wili ana). ʻOiai he mōʻaukala lōʻihi ko nā ʻāpana PDC o ka holomua, ke hoʻomau nei lākou i ka ulu a hoʻomaikaʻi mau ma o nā kihi ʻoki hou a me nā mea hou, nā hoʻonohonoho, a me nā mea. He kūpono loa kēia mau ʻāpana i ko lākou hana ʻana e ʻoki i nā ʻano pōhaku ma mua o ka wāwahi ʻana iā lākou. I kēlā me kēia makahiki, hoʻomaikaʻi nā holomua hou i ka ʻenehana i ka pono o nā ʻāpana PDC a hoʻomaikaʻi i ka wikiwiki o ka ʻeli ʻana.

Ua kapa ʻia kēia mau ʻāpana ʻo nā ʻāpana "ihu-a-ka-wili" o ka ʻoihana ʻeli - hoʻopau lākou i ka hana a hiki ke lilo i mea kūpono loa no nā ʻano lawelawe like ʻole a me nā ʻano hoʻokumu ʻana—ʻaʻohe ʻāpana neʻe e paʻa, ʻaʻohe hoʻoluhi, he ʻeli pono wale nō no kāu mau pono āpau.

He aha nā PDC Bits?

Aia ʻelua mau kaila nui oNā ʻāpana wili PDC– nā ʻāpana PDC kino matrix a me nā ʻāpana PDC kino kila. He ʻāpana poepoe like ke ʻano o nā ʻāpana ʻelua me ʻehā a ʻewalu mau ʻano ʻoki, a i ʻole nā ​​pahi, e pālahalaha ana mai waenakonu. A laila ua kau ʻia kēlā me kēia pahi ma luna me nā mea ʻoki ma waena o ʻumi a me kanakolu. Loaʻa i nā ʻāpana nā kahawai wai i hoʻopuehu ʻia no ka hoʻomaʻalili ʻana, a aia kahi nozzle ma ka piko o ka pahi. Inā ʻoe e hoʻāʻo nei e noʻonoʻo i kēia ʻāpana, ua like ia me ka lei aliʻi e ʻaʻahu ai ke aliʻi.

Hoʻohana ʻia nā ʻāpana PDC no ka ʻeli ʻana i ka ʻaila a me ke kinoea, ka ʻeli ʻana o ka geothermal, ka ʻeli ʻana i ka luawai wai, ka ʻeli ʻana i ke kūkulu ʻana, ka hana mining a me ka ʻeli ʻana i ke kuhikuhi ākea.

ʻO ka ʻepekema ma hope o nā PDC Bits

Ua aʻo paha ʻoe ma ke kula ʻo ka daimana ka mea paʻakikī loa i ʻike ʻia e ke kanaka. ʻOiaʻiʻo nō! A he kūpono loa ia no ka ʻoki ʻana i nā mea ʻē aʻe e like me nā ʻano pōhaku no ka ʻeli ʻana.

Hoʻohana nā ʻāpana PDC i nā daimana liʻiliʻi, makepono, i hana ʻia e ke kanaka i loko o kā lākou mau ʻāpana ʻoki. He paʻakikī ke kaʻina hana o ka hana ʻana i nā daimana ma luna o kēia mau ʻāpana. I ka hoʻomaʻalahi ʻia, eia ke kaʻina hana no ka hana ʻana i nā ʻāpana wili daimana:

• Hana ʻia nā daimana synthetic liʻiliʻi
• A laila ua hōʻuluʻulu ʻia nā daimana i loko o nā puʻu nui o nā kristal
• A laila hoʻohālikelike ʻia nā kristal i mau papa daimana
• A laila hoʻopaʻa ʻia nā papa daimana i ka metala, ʻo ia hoʻi ka tungsten carbide, a me kahi mea hoʻopaʻa metala.
• Lilo kēia i ʻāpana ʻokiʻoki o ka ʻāpana - he nui nā mea ʻokiʻoki ma kēlā me kēia lau o ka ʻāpana
• A laila hoʻopili ʻia nā mea ʻokiʻoki i nā pahi, i hoʻopili ʻia i ke kino o ka ʻoki liʻiliʻi

I ka hui pū ʻia, hoʻohana ʻia nā mea ʻoki a me nā pahi ma ka piko o ka ʻāpana PDC e ʻoki i nā ʻano pōhaku like ʻole.

Nā Daimana Hana ʻia i loko o nā ʻāpana wili

E like me kāu e ʻike ai, ʻo nā daimana synthetic nā mea nui no nā ʻāpana PDC. I ka hana ʻana i kēia mau ʻāpana, hana ʻia nā hua liʻiliʻi loa o ke daimana (i kapa ʻia hoʻi he diamond grit). He paʻa loa kēia grit akā lilo ia i mea paʻa ʻole ma kahi pae molekala ke wela. No laila, ʻoi aku ka nui o ka hemahema o kāu ʻāpana PDC inā ʻaʻole i hoʻomaʻalili pono ʻia i ka wā e hoʻohana ʻia ai.

Akā naʻe, he kūpaʻa loa nā daimana synthetic i ke komo ʻana; ʻo ia ka mea kūpono no ke ola lōʻihi a me ke kūpaʻa. Hoʻololi ke ʻano metala inā koho ʻoe i kahi ʻāpana matrix a kila paha - akā he mea koʻikoʻi ke daimana. Hiki i nā ʻāpana PDC ke loaʻa ke ola lōʻihi inā e hoʻomaʻalili pono ʻia.
