Rotary tricone bit IADC517 12 1/4″ (311mm)
Hōʻike huahana
ʻO ka API rotary tricone roller cones bits i loko o ke kumukūʻai mai ka hale hana ʻo Kina ka mea mau no kāu wili 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 12 1/4 iniha (311mm) ka nui maʻamau i ka wili luawai hohonu e like me ka luawai aila a me ka luawai kinoea, a he nui maʻamau nō hoʻi ia i ka hoʻoheheʻe ʻana i ka lua hoʻokele.
Wahi a ka mea ʻokiʻoki, loaʻa i ka tricone bit ke ʻano o TCI (Tungsten Carbide Insert) a me Steel Tooth.ʻO IADC517 ka TCI tricone bit.
ʻO ke kūkulu ʻana:
ʻO ke kiʻekiʻe precision journal bearing with two thrust faces, Balls lock the cone.Hardfaced head bearing surface.Cone bearing inlaid with friction-reducing alloy and then silver-plated.Abrasion resistance and seizure of the bearing are improved.and kūpono no ke kiʻekiʻe rotary speed.
Sila a me ka Lubrication:
ʻO ka pūʻolo hoʻopaʻa metala kiʻekiʻe he ʻelua sila metala a me ʻelua elastic energizers.Compressed energizers e hōʻoia i ka hoʻopili maikaʻi ʻia ʻana ma luna o ʻelua mau wahi sila o nā apo metala e ka ikaika elastic, a hoʻokō i ke sila bearing. ʻO kēia ka mea e hoʻomaikaʻi ai i ka hilinaʻi a me ka lōʻihi o ka lawe ʻana i ke sila.
