Rotary tricone Bits IADC517 9 7/8″ (250mm) no ka pōhaku paʻa
Hōʻike huahana
ʻO nā ʻāpana API tricone i loko o ke kumukūʻai mai Kina ka mea hoʻolako mau no kāu ʻoihana maikaʻi maikaʻi.
Wahi wehewehe:
IADC: 517 - TCI i hoʻopaʻa ʻia i ka bit bearing bit me ka pale ana no nā ʻano palupalu palupalu a me ka haʻahaʻa me ka ikaika compressive haʻahaʻa.
Ka ikaika compressive:
85 - 100 MPA
12,000 - 14,500 PSI
Ka wehewehe ʻāina:
ʻO nā pōhaku ʻoʻoleʻa a me nā pōhaku paʻa e like me ke one me nā ʻōniʻoniʻo o ka quartz, ka limestone paʻakikī a i ʻole ka chert, hematite ores, paʻakikī, paʻa maikaʻi ʻia nā pōhaku abrasive e like me: nā pōhaku one me ka quartz binder, dolomites, quartzite shales, magma a me ka metamorphic coarse grained pōhaku.
Hiki i ka Far Eastern Drilling ke hāʻawi i nā tricone drill bits i nā ʻano nui (mai 3 7/8” a 26”) a me ka hapa nui o nā Codes IADC.
ʻO 9 7/8 iniha (250mm) ka nui maʻamau i ka wili luawai hohonu e like me ka ʻaila ʻaila a me ka luawai kinoea, a he nui maʻamau nō hoʻi ia i ka hoʻoheheʻe ʻana i ka lua hoʻokele.
Ma muli o ka mea ʻokiʻoki, loaʻa nā ʻāpana drill rubber silicone ma TCI (carbide insert) a me nā ʻano niho kila. ʻO iADC517 kahi ʻano TCI silicone rubber drill bit.
Kūleʻa halihali.
ʻO ke kiʻekiʻe kiʻekiʻe e pili ana i ka puke moʻolelo me nā ʻaoʻao ʻelua, ʻo ka cone lock ball, ka ʻili paʻa o ke poʻo, ka cone bearing inlaid me ka friction reducing alloy a laila i uhi ʻia i ke kālā, kahi e hoʻomaikaʻi maikaʻi ai i ke kūpaʻa ʻaʻahu a me ke kūʻē ʻana o ka bearing a kūpono no ka wikiwiki kiʻekiʻe.
ʻO ka sila a me ka lubrication.
ʻO ka pūʻolo sila metala kiʻekiʻe he ʻelua sila metala a me ʻelua mea hoʻopaʻa elastic. Hoʻopaʻa nā mea hoʻopaʻa paʻa i ka pilina maikaʻi ma waena o nā ʻāpana hoʻopaʻa ʻelua o nā apo metala ma o ka ikaika elastic e hiki ai ke hoʻopaʻa ʻia o nā bearings. I ka wili ʻana, ʻoi aku ka ikaika o nā sila metala ʻoiai ke kūpaʻa nei nā mea paʻa, e hoʻomaikaʻi ai i ka hilinaʻi a me ka lōʻihi o ke sila bearing, ʻoiai ʻo ka ʻōnaehana uku kaomi a me ka momona kiʻekiʻe hiki ke hoʻomaikaʻi nui i ka hilinaʻi o ka lubrication.
