Wholesale API i hoʻopilikino ʻia i ka tricone rock bit ma ke kumukūʻai e pili ana i ka haʻahaʻa haʻahaʻa a me ka maikaʻi maikaʻi loa no ka wili luawai hohonu.
1) Drill Bit Connection i hana ʻia e like me ka maʻamau API.
2) Hiki iā mākou ke hoʻololi i ka nui bit e like me kāu rig.
3) Hiki ke loaʻa ka hopena maikaʻi loa ma o ka hoʻohana ʻana i ka bits-tooth bit i loko o ka stratum palupalu. Inā ʻoi aku ka paʻakikī o ka mining, ʻōlelo ʻia ʻo TCI tricone bit.
4) Ke hoʻomau nei nā ʻokiʻoki i hōʻoia ʻia a me nā hoʻolālā ʻana i kahi pae kiʻekiʻe o ka hana a me ka hilinaʻi.
5) Hāʻawi ka hydraulics i hoʻonui ʻia i ka ROP ma o ka wehe ʻana i nā ʻokiʻoki a me ka hōʻoia ʻana i ke komo ʻana o ka pōhaku hou ma kēlā me kēia ʻoki ʻoki ʻana.
