Nā ʻano like ʻole o ka ʻeli ʻana a me nā ʻāpana luawai

ʻO nā ʻāpana mining a me ka ʻeli ʻana maikaʻi nā ʻāpana lua e wili ai a komo i nā mea pōhaku palupalu a paʻa. Hoʻohana ʻia lākou i ka mining, well drilling, quarrying, tunneling, construction, geological exploration, and blasting applications.

Hoʻokomo pinepine ʻia nā ʻāpana mining a me ka wili ʻana i kahi pilina pili no ka hoʻopili ʻana i kahi drillstring a me kahi kino puha kahi e kahe ai ka wai drill. Pono nā wai wili e hoʻomaʻemaʻe i nā ʻoki wili, hoʻomālili i ka bit, a hoʻopaʻa i ka pā lua. ʻO nā ʻano o nā bit drilling well nā mea penei:

Tri-cone a i ʻole nā ​​ʻāpana ʻōwilii loko o ʻekolu cones niho, kēlā me kēia me kahi kihi puke pai i hoʻokū ʻia i ke koʻi mua o ka bit. Hoʻololi ʻia ke kihi puke pai e like me ka paʻakikī o ka hoʻokumu ʻana. ʻO nā niho o kēlā me kēia cone e pili ana kekahi i kekahi e hoʻopā i ka lepo paʻa. Hoʻokele ʻia ka bit e ka mea kaumaha ma ka bit (WOB) ʻoiai e huki ʻia ana e ka hana wili o ke poʻo drill bit.

Nā ʻāpana hāmare ma lalo o ka lua (DTH).hoʻohana ʻia me nā hāmare Down-the-hole no ka ʻeli ʻana i nā lua ma waena o nā ʻano pōhaku ākea. I ka hui pū ʻana me nā hāmare DTH, ua hoʻolālā ʻia nā ʻāpana hammer drill me kahi pahu splined no ka hoʻohuli ʻana i ka bit i ka lepo. ʻO nā bits DTH nā ʻāpana poʻo paʻa i loaʻa nā mea hoʻokomo bit conical a chisel i hoʻopaʻa ʻia i loko o kahi matrix e pili ana i ke poʻo drill bit. ʻO ka hoʻonohonoho poʻo o ka bit he convex, concave, a pālahalaha paha.

PDC bitsme ka polycrystalline diamond compact (PDC) hoʻokomo i hiki ke kapa ʻia he mau ʻāpana PDC. ʻAʻole like me nā tricone bits, PDC drill bits he hoʻokahi ʻāpana kino me ka ʻole o nā ʻāpana neʻe a hoʻomohala ʻia e mau; Hoʻolālā ʻia kēlā me kēia bit i loko o ka hale no ka hana, ka paʻa a me ka hilinaʻi. E koho i ka Matrix a i ʻole ke kila ikaika kiʻekiʻe e kūpono i nā noi wili like ʻole.

Nā ʻāpana pihiua like ia me nā bits DTH nā ʻāpana poʻo paʻa i loaʻa nā mea hoʻokomo bit conical a chisel i hoʻopaʻa ʻia i loko o kahi matrix e pili ana i ke poʻo drill bit. ʻO ka hoʻonohonoho poʻo o ka bit he convex, concave, a pālahalaha paha. ʻO ka bit pihi ʻo ia ka ʻāpana poepoe a pau i kūpono no ka nui o ka pōhaku paʻa, nā noi wili hāmare kiʻekiʻe.

ʻO nā ʻāpana keʻa a me nā ʻāpana chiselhe mau ʻāpana poʻo paʻa i hoʻopaʻa ʻia i ke kila a i ʻole nā ​​lau carbide. Wehewehe ʻia nā ʻāpana chisel e ka maka hoʻokahi a ʻo nā ʻāpana keʻa he ʻelua a ʻoi aʻe paha nā lau e hele ana ma waenakonu o ka bit. Hoʻopiʻi pinepine ʻia nā lau i lalo i ka ʻili ʻoki.
