ʻO ka ʻūmiʻi ʻeli API Tricone IADC517 8 3/4 ʻīniha (222mm) i loko o ka waihona
Wehewehe Huahana
ʻO ka Pōmaikaʻi o ka Tricone Bit:
1). Kino kila kila i hoʻoheheʻe ʻia
2) Palekana Nect
3) Nā niho Carbide me ka metala paʻakikī
4) ʻIli hoʻoheheʻe me ka metala paʻakikī
5) Mea pale kaula ʻoihana
6) Hale hana API a me ISO
Nā Hiʻohiʻona Nui
a). Aia kahi tricone kūpono no kekahi ʻano pōhaku.
b). He maʻalahi ka ʻoki Tricone a hiki ke lawelawe i nā ʻano hoʻololi.
c). Kūpono ke kumukūʻai o nā cone Tri, lōʻihi ke ola a he wikiwiki ka ʻeli ʻana.
d). Loaʻa i nā cone roller ka bearing sila kiʻekiʻe: tungsten carbide kiʻekiʻe loa a me ka pale ana o ke ana daimana ma loko o ka drill bit a me ka skirt tail hard facing a me ka hydraulics i hoʻonui ʻia. Ua hoʻolālā ʻia kēia mau roller cone drill bits e hele i nā hohonu loa i nā kūlana koʻikoʻi a ma nā kūlana kahi hiki ʻole ai iā lākou ke hāʻule.
