ʻO ka ʻāpana wili tricone API & ISO IADC537 26″(660.4mm)

Wahi a ka mea ʻoki, hiki ke hoʻokaʻawale ʻia ka ʻāpana tirocne i ka ʻāpana TCI a me ka ʻāpana Steel Tooth Bit.
He pōkole ʻo TCI no Tungsten Carbide Insert, ʻo ka tungsten carbide kahi mea paʻakikī maʻamau i ke kahua ʻeli pōhaku, ʻo kekahi mea ʻē aʻe he daimana.
ʻO nā mea hoʻokomo ke ʻano o nā niho Tungsten Carbide e kūpono ana ma nā cones o nā ʻāpana wili wili rotary. ʻO ka ʻāpana wili API TCI tricone. ʻO ka pilina kaula API o IADC537 26" he 7 5/8 reg pin. No ka nui o ka 26" tricone bit, kapa mākou i ka 660mm tricone bit.

Loaʻa i kā mākou mau ʻāpana ke ʻano o ka Rubber / Elastomer sealed bearing a me ka Metal sealed bearing. Manaʻo mākou e koho mākou i nā ʻāpana metala sealed bearing no nā lua pōhaku hohonu me nā ʻano paʻakikī. No ka ʻeli ʻana i ka lua hohonu loa, paipai mākou i nā ʻāpana tricone metala sealed bearing ma ka hohonu o ka ʻeli ʻana ma mua o 1000 mika. No ka pōhaku paʻakikī a me ka ʻeli ʻana i ka lua hoʻokele ʻauwaha mamao loa i ʻoi aku ka lōʻihi ma mua o 300 mika. Paipai pū mākou i nā ʻāpana tricone metala sealed bearing. No ka ʻeli ʻana i ka lua wai, ka ʻeli ʻana i ka lua pāpaʻu a i ʻole nā ​​papahana ʻeli ʻana i ka lua hoʻokele ʻauwaha mamao pōkole, ʻoi aku ka maikaʻi o ke kumukūʻai o nā ʻāpana tricone metala sealed bearing (rubber).
