ʻO ka ʻeli ʻana o ka tricone API IADC127 4 5/8 ʻīniha (118mm) no ke kūʻai aku

ʻO nā ʻāpana wili pōhaku tricone niho kila API kūʻai nui i ka waihona ma muli o ke kumukūʻai haʻahaʻa loa a me ke ʻano maikaʻi loa mai ka hale hana Kina
Wehewehe ʻana o ka Bit:
IADC: 127 - ʻĀpana paʻa niho kila me ka pale ana no nā ʻano palupalu me ka ikaika compressive haʻahaʻa a me ka hiki ke wili kiʻekiʻe.
Ikaika Hoʻopaʻa:
0 - 35 MPA
0 - 5,000 PSI
Wehewehe ʻĀina:
Nā pōhaku palupalu loa, ʻaʻohe papa, ʻaʻole i hoʻopaʻa pono ʻia e like me nā lepo lepo a me nā one pōhaku i hoʻopaʻa pono ʻole ʻia, nā pōhaku limestone marl, nā paʻakai, ka gypsum, a me nā lanahu paʻakikī.
Hiki iā mākou ke hāʻawi aku i nā ʻāpana wili niho a me nā ʻāpana wili TCI tricone i nā nui like ʻole (mai 3 7/8” a i 26”) a me ka hapa nui o nā Code IADC.

Wahi a ke ʻoki ʻana i nā mea, hiki ke hoʻokaʻawale ʻia ʻekolu mau ʻāpana cone i ka ʻāpana TCI a me ka ʻāpana Milled Tooth
ʻO nā ʻāpana tricone niho kila he inoa ʻē aʻe ʻo ka milled tooth tricone bit ʻoiai ua hana ʻia nā niho e ka mīkini wili, ua paʻakikī ka ʻili cone e ka tungsten carbide.
ʻO ka niho wili ʻia ʻo IADC127 no ka hoʻokumu palupalu loa. He mea nui loa ke koho ʻana i nā ʻāpana wili pōhaku kūpono ma mua o ka hoʻomaka ʻana i ka papahana.
Hiki i ka paʻakikī o nā pōhaku ke palupalu, waena a paʻakikī a paʻakikī loa paha, hiki ke ʻokoʻa iki ka paʻakikī o kekahi ʻano pōhaku, no ka laʻana, ka limestone, ka sandstone, he limestone palupalu ka shale, ka limestone waena a me ka limestone paʻakikī, ka sandstone waena a me ka sandstone paʻakikī, a pēlā aku.
