Nā ʻāpana pōhaku Tricone IADC537 6 ʻīniha (152.4 mm)

Kūʻai nui ʻia nā pihi pihi API no ka wili ʻana no ka puka waena.
ʻO ka hana maʻamau TCI tricone bit IADC537
E hoʻohana ʻia ka bit tricione IADC537 no nā ʻano haʻahaʻa haʻahaʻa me ka ikaika compresseive haʻahaʻa, e like me ka waena, ka haʻalulu palupalu, ka limestone haʻahaʻa haʻahaʻa.
6" ʻO Tricone Bits he anawaena maʻamau no ka puka hoʻokele HDD, aia kēia kŘkohu he 3 lateral jet nozzles, ʻoi aku ka maikaʻi o ka hana hydraulic ma mua o ka lua jet waena i ka hoʻomaʻemaʻe ʻana i nā ʻāpana pōhaku nui loa i ka ʻeli ʻana i nā pōhaku paʻa. ka mea oki.
Hoʻolālā ʻia ka nui a me ke kiʻekiʻe o ka TCI maikaʻi e hiki i ka ROP maikaʻi loa (Rate of Penetration), ua hoʻopaʻa ʻia ka bearing e Elastomer O-ring, a hoʻopaʻa ʻia nā lima e nā mea hoʻokomo TC.
ʻO ka pilina pili pae maʻamau API no 6 iniha (152.4mm) tricone bit he 3 1/2 reg pin.Hiki iā mākou ke hana i ka pili thread siutable e like me nā koi o ka mea kūʻai aku.
