Piko API pōhaku drill bit IADC537 8 3/4″(222.2mm) me ke kumu kūʻai hoemi
Hōʻike huahana
Wholesale API pihi rock roller drill bits IADC537 8 3/4" no ka lua hohonu i loko o ka waihona mai Kina hale hana
Nā hiʻohiʻona nui
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 ka hoʻohana ʻana i ka biti niho kila i loko o ka stratum palupalu.Inā ʻoi aku ka paʻakikī o ka mining, ʻōlelo ʻia ʻo TCI tricone bitis.
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 pono ʻana i nā ʻokiʻoki a me ka hōʻoia ʻana i ke komo ʻana o ka pōhaku hou ma kēlā me kēia.
ʻoki ʻana ka hoʻololi ʻana.
