hale hana API o Roller cone bit IADC637 3 7/8″ (98mm) ma ka waihona
Hōʻike huahana
Kūʻai nui API TCI tricone roller cone drill bits me ke kumu kūʻai hoʻemi ma ke kumukūʻai mai Kina ka mea hoʻolako no ka wili luawai.
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 iā mākou ke hāʻawi i nā ʻāpana TCI i nā ʻano nui (mai 3 3/8" a i 26") a me ka hapa nui o nā code IADC.
1> ʻO nā mea hoʻokomo tungsten carbide ka uku ma nā cones, pale pale a me nā kua lima.
2> Ua kūpono nā mea hoʻokomo tungsten carbide i ke ana o nā cones i hōʻike ʻia i nā ʻāpana mai ka emi ʻana, ʻaʻohe hopohopo o nā drillers no ka lua hohonu a me ka wili pōhaku paʻakikī.
3> O-ringi maikaʻi, ʻoi aku ka maikaʻi o ka hoʻopaʻa ʻana i ka sila a me ka hoʻolālā seal curved e hoʻonui i ka hana sila.ʻO ka ʻōnaehana uku kaomi a kikoʻī
hoʻonui nui ka momona i ka hilinaʻi lubricating.
