Pehea ka hiki ʻana mai o nā Tri-Cone Bits i hoʻololi i ka ʻoihana mining

ʻO nā ʻāpana drill tri-cone kekahi o nā metala ʻōpala hoihoi loa ma ka mākeke i kēia mau lā. ʻAʻole wale kēia mau ʻāpana tri-cone i loko o ka metala tungsten lōʻihi, aia nā cobalt a me nā nickel binders i hoʻohana ʻia e hoʻohui i kēlā me kēia wahi mai 3% a 30% paona, hiki ke hoʻohana hou ʻia no nā kumu wili inā maikaʻi lākou.

Ua hoʻololi nā ʻāpana drill tri-cone i ka ʻoihana wili a me ka eli. Ma mua o kēia mau mea hana kōkua, ua hana ʻia ka wili ʻana ma ka "lima kila," pono e paʻa i ke kui a me ka hāmare a paʻi pinepine i ka pōhaku. ʻO ka hope loa, i ka makahiki 1930, ua hana ʻelua mau ʻenekinia i ka pahu drill tai-cone, nona ʻekolu mau ʻāpana cone. ʻO ka patent no kēia mea hana hou, i hoʻomohala ʻia e Ralph Neuhaus, i mau a hiki i 1951, a ma hope o ka hopena o nā hui ʻē aʻe he nui i kā lākou mau ʻāpana.

ʻO ka maikaʻi o kēia mau ʻāpana coned hou ʻekolu i hoʻololi maoli i ke ʻano o ka hana ʻana a me ka ʻeli ʻana a hoʻololi i nā haneli haneli o nā ʻoihana ma hope.

I ka hoʻohana ʻia ʻana o ka metala tungsten no kēia mau ʻāpana tri-cone, ua puka mai kekahi pōmaikaʻi nui o kēia mea hana hou: ka pale wela. No ka mea he kiʻekiʻe ka helu heheʻe ʻana o ka tungsten, ua hiki i nā ʻāpana tungsten ke kū i nā mahana kiʻekiʻe a ua hiki i nā drillers ke wili hou i nā kumu paʻakikī. Ma waho aʻe o kona pale ʻana i ka wela, hiki i ka tungsten ke hana wikiwiki aʻe ma mua o nā mea ʻē aʻe, e ʻae ai i ka wili kiʻekiʻe.

Ua hala nā lā e hoʻohuli ai ka poʻe miners i kā lākou ʻokiʻoki a hahau me ka hāmare e wāwahi i ka hale paʻa. Ma muli o ka hana ʻana o ka bit drill tai-cone, ʻoi aku ka maʻalahi o ka wili ʻana ma o nā ʻano pōhaku palupalu, waena, a paʻakikī loa.

ʻOiai ʻoi aku ka ikaika o nā bits tungsten carbide a hiki ke lōʻihi ma mua o nā mea drill ʻē aʻe, e mau ana lākou i ka wā a pono e hoʻololi ʻia. He mea nui ʻaʻole e hoʻolei wale i kēia mau ʻāpana tungsten tri-cone, akā naʻe, no ka mea, ʻoi aku ka hauʻoli o nā ʻoihana hana hou tungsten e hoʻololi i ke kālā no kēia mau hoʻokomo carbide ikaika.

Nā pōmaikaʻi ʻo Tricone Bit ma ka hōʻuluʻulu ʻana:

• ʻenehana hoʻāʻo manawa

• Hiki ke hoʻololi

• Kumukuai Haahaa

• Hoʻokō Rock Paʻa

ʻO ka maikaʻi loa o nā drillers ma ka hoʻohana ʻana i nā tricone bits ʻo ia ke kumu o ka manawa. ʻO ka hoʻāʻo ʻana i ka manawa o kēia ʻenehana ua hoʻomaikaʻi nui i kāna 'hana holoʻokoʻa a me ka hana ʻana i ka make-up. ʻO ka makemake kaulana o nā ʻāpana huila i ke kenekulia i hala ua ʻae i nā mea hana hoʻolālā e hoʻopaʻa pono i kēlā me kēia ʻaoʻao o kēia drill bit. ʻOiai aia ka ʻenehana hou i ka wā kamaliʻi o ka evolution, ua hiki ka tricone i kahi kiʻekiʻe o ka hana. ʻO ka hoʻohui ʻana i ka hoʻomaikaʻi mau ʻana i nā mea koʻikoʻi e like me Tungsten Carbide Inserts a me Sealed Journal Bearings ua hoʻonui nui i nā hopena a me ka hilinaʻi ʻana a lilo ia i mea hoʻokahi o nā mea hana kiʻekiʻe ma ka mākeke wili.

ʻO kekahi pōmaikaʻi ʻē aʻe no nā mea hoʻoheheʻe e hoʻohana ana i ka ʻāpana cone roller ʻo ia ka maʻalahi o ka hana. Ke loaʻa i kahi kūlana paʻakikī, loaʻa i nā drillers ka nui o nā koho me nā mea like me Torque a me Weight On Bit ʻaʻole lākou e hāʻawi ʻia i ka wā e wili ai me kahi bit PDC. ʻOi aku ka maikaʻi o nā ʻāpana Tricone no nā hana e kū pono ana i nā ʻano pōhaku paʻakikī. ʻO ka neʻe ʻana o kēlā me kēia wili ʻekolu e wāwahi i ka pōhaku, e ʻoi aku ka malleable no ka holomua.

ʻO ke kumukūʻai holoʻokoʻa kahi pōmaikaʻi ʻē aʻe i ka hoʻohana ʻana i kēia mau bits. Ma nā hana kahi i ʻae ʻole ai ka waihona kālā no ke kumukūʻai o ka hoʻohana ʻana i kahi PDC, hiki i kahi tricone bit ke lilo i hoʻoholo waiwai kūpono no ka hana.

ʻO mākou kahi mea hoʻolako tricone bit. Inā makemake ʻoe e aʻo hou e pili ana i nā tricone bits, e kelepona mai iā mākou i kēia lā!
