ʻO ke code IADC he pōkole ia no "International Association of Drilling Contractors".
Ho'ākāka ke Code IADC no nā Tricone Bits i kona hoʻolālā bearing a me nā hiʻohiʻona hoʻolālā ʻē aʻe (SHIRT TAIL, LEG, SECTION, CUTTER).
Hoʻomaʻalahi nā code IADC i nā mea ʻeli e wehewehe i ke ʻano o ka ʻāpana pōhaku a lākou e ʻimi nei i ka mea hoʻolako.
Hahai ʻo Far Eastern i ka ʻōnaehana hoʻokaʻawale bit IADC kahi e hoʻokaʻawale ai nā huahelu ʻekolu mua i ka bit e like me ke ʻano i hoʻolālā ʻia e wili a me ka hoʻolālā bearing/seal i hoʻohana ʻia.
Ka wehewehe ʻana o ke code IADC no ka hua mua:
Hoʻokaʻawale ʻo 1,2, a me 3 i nā ʻāpana niho kila me 1 no ka palupalu, 2 no ka waena a me 3 no nā ʻano paʻakikī.
Ua kapa ʻia ʻo 4,5,6,7 a me 8 nā TUNGSTEN CARBIDE INSERT BITS no nā ʻano paʻakikī like ʻole me 4 ka palupalu loa a ʻo 8 ka paʻakikī loa.
Ka wehewehe ʻana i ke code IADC no ka helu ʻelua:
ʻO 1,2,3 a me 4 nā haki hou o ke kūkulu ʻia ʻana me 1 ka palupalu loa a ʻo 4 ka paʻakikī loa.
Ka wehewehe ʻana o ke code IADC no ka helu ʻekolu:
1 a me 3: ʻāpana wili hāmama maʻamau (ʻaʻole i sila ʻia ka wili wili)
2: ʻO ke kūlou hāmama maʻamau no ka ʻeli ʻana i ka ea wale nō
4 a me 5: ʻāpana bearing sila ʻia me ka wili
6 a me 7: ʻāpana bearing i hoʻopaʻa ʻia i ka puke pai
Hoʻomaopopo:
*ʻOkoʻa ma waena o 1 a me 3:
3 me ka hoʻokomo carbide ma ke kuʻekuʻe wāwae o ke cone, ʻoiai 1 me ka ʻole
*ʻOkoʻa ma waena o 4 a me 5:
5 me ka hoʻokomo carbide ma ke kuʻekuʻe wāwae o ke kone, ʻoiai 4 me ka ʻole.
*ʻOkoʻa ma waena o 6 a me 7:
7 me ka hoʻokomo carbide ma ke kuʻekuʻe wāwae o ke kone, ʻoiai 6 me ka ʻole.
Ka wehewehe ʻana i ke code IADC no ka huahelu ʻehā:
Hoʻohana ʻia nā code leka ma lalo nei ma ke kūlana huahelu ʻehā e hōʻike i nā hiʻohiʻona hou aʻe:
A. Noi ʻana i ka ea
R. Nā Kuʻina i Hoʻoikaika ʻia
C. Waena Jet
Niho kila maʻamau S.
D. Ka Mana Hoʻololi
Hoʻokomo ʻokiʻoki X
E. Ka mokulele i hoʻolōʻihi ʻia
Y. Hoʻokomo Conical
G. Palekana Ana Keu
Z. ʻAno Hoʻokomo ʻē aʻe
Ka Hoʻokuke ʻana o J. Jet
Nā ʻAno Bearing:
ʻEhā (4) ʻano o nā hoʻolālā bearing i hoʻohana ʻia i nā ʻāpana wili trcione:
1) ʻO ka Bit Roller Bearing Open maʻamau:
Ma luna o kēia mau ʻāpana e milo manuahi nā cone. Loaʻa i kēia ʻano ʻāpana kahi lālani mua o nā bearings pōpō a me kahi lālani hope o nā bearings wili.
2）: ʻO ka ʻāpana Roller Bearing Open maʻamau no ka ʻeli ʻana i ka ea
Ua like nā cone me #1, akā loaʻa ka ea i hoʻokomo pololei ʻia i nā cone e hoʻomaʻalili i nā bearings. Holo ka ea i loko o ka cone ma o nā ala hele i loko o ke pine. (ʻAʻole no nā noi lepo)
3) Nā ʻāpana wili i hoʻopaʻa ʻia
Loaʻa i kēia mau ʻāpana kahi sila O-Ring me kahi waihona momona no ka hoʻoluʻu ʻana o ka bearing.
Hana nā sila ma ke ʻano he pale e kūʻē i ka lepo a me nā ʻokiʻoki e hoʻolele i nā bearings.
4) Nā ʻāpana ʻōwili e hāpai ana i ka puke pai
Hoʻomaʻalili wale ʻia kēia mau ʻāpana me ka ʻaila/aila i hoʻomaʻalili ʻia me nā bearings ihu, sila O-ring a me kahi heihei no ka hana maikaʻi loa.
Loaʻa i nā Far Eastern Tricone Bits ka bearing sila rapa a me ka bearing sila metala.
