Nā ʻāpana huila Rotary IADC637 9 7/8 ” (250.8mm)
Hōʻike huahana
Wholesale API TCI tricone drill bits me ke kumu kūʻai hoʻemi i ka waihona mai Kina hale hana no nā hana paʻakikī.
Wahi wehewehe:
IADC: 637 - ʻO ka puke pai TCI i hoʻopaʻa ʻia i ka bit bearing bit me ka pale ana no nā hana paʻakikī waena me ka ikaika compressive kiʻekiʻe.
Ka ikaika compressive:
100 - 150 MPA
14,500 - 23,000 PSI
Ka wehewehe ʻāina:
ʻO nā pōhaku paʻakikī a paʻa maikaʻi e like me: nā limestone silica paʻakikī, nā streaks quarzite, pyrite ores, hematite ores, magnetite ores, chromium ores, phosphorite ores a me granite.
Hiki i ka Far Eastern Drilling ke hāʻawi i nā bit TCI i nā ʻano nui (mai 3 3/8" a i 26") a me ka hapa nui o nā code IADC.
ʻO 9 7/8" he 250mm ka anawaena, ʻo ka pilina o ke kaula he 6 5/8 reg pin e like me ka kikoʻī API.
IADC537 'o ia ho'i, ua kūpono ka tricone roller bit no ka wili 'ana i nā pōhaku 'o'ole'a e like me quartzite streaks,granites, etc. Ua ho'opa'a 'ia ka bearing e ho'onui i ke ola hana.
ʻO Tungsten carbide inserts (TCI) he mea paʻakikī loa i ka wili ʻana i nā pōhaku paʻakikī, ua hoʻokomo piha ʻia ka kuʻekuʻe wāwae o nā cones a me nā lima-hoʻi me nā niho Tungsten Carbide.
He mea maʻamau ka nui ma ke kahua mining, e wili i ka lua pahū. I ka ʻeli ʻana i ka mining, ʻo ka helu mua no ka code IADC he 6,7,8, a ʻo ke kolu ka helu maʻamau ʻo 2 a me 5.
Wahi a ka IADC kikoʻī no ka tricone bit,"2" ʻo ia hoʻi ke ʻano o ka ʻili wili hāmama maʻamau, a ʻo "5" ʻo ia hoʻi ka sila i hoʻopaʻa ʻia i ka ʻili pahu pahu me ka pale ana.
I kekahi mau ʻāina, hoʻohana pinepine ʻia ka 9 7/8"(250.8mm) e wili i ka wai a me ka luawai geothermal. Hoʻopili ʻia ka rig rig e ka wai lepo, ma kahi o ka hoʻoemi ʻana i ka ea.
No laila, no nā noi like ʻole, pono mākou e koho i nā ʻāpana tricone roller kūpono.

ʻO Far Eastern ka hale hana kūikawā i nā bits drill, e like me nā tricone bits, PDCs bits, HDD hole opener, Foundation roller cutters no nā noi like ʻole. HDD, Kūkulu a me ke kahua...
Ma ke ʻano he hale hana drill bits ma Kina, e hoʻonui i ke ola hana drill bit kā mākou pahuhopu. Ke ho'āʻo mau nei mākou e hoʻomaikaʻi i nā bits me nā helu komo kiʻekiʻe. ʻO kā mākou misionari e hoʻohaʻahaʻa i ke kumukūʻai o ka drilling-per-meter. .ʻO kā mākou kumu e kūʻai aku i ke kūlana kiʻekiʻe me ke kumu kūʻai haʻahaʻa.
