ʻO JD125A 12 ʻīniha kiʻekiʻe i lalo i ka hāmare wili lua no ka luawai a me ka mining

Ma ka DTH drilling, ʻo ka bit drilling bit ka hoʻomau ʻana o ka shank, ka mea e paʻi pololei ai ka piston drill rock.No ka pili pono o ka piston me ka bit drill, nalowale ka ikehu.Hāʻawi kēia i ka hoʻoheheʻe ʻana iā DTH i kahi helu komo mau me ka nānā ʻole i ka lōʻihi o ka lua.

Hoʻopili ʻia nā bits DTH me kā lākou hāmare like (ma ka ʻeli ʻana i ka anawaena puka a me ka hoʻonohonoho spline).Hiki i nā mea kūʻai ke hana i kā lākou DTH bits ma nā ʻano like ʻole, e like me ka hoʻololi ʻana i ka profile insert tungsten carbide (spherical, ballistic, etc.), ʻaoʻao helehelena (flat face, concave, convex, etc.), a me nā lua flushing.

• Nā anawaena wili liʻiliʻi a nui
• Ke hana nei ma ka laulā puʻe kiʻekiʻe, hiki ke ʻeli i ka lōʻihi o ka lua.

Nā pono:

1. Hāʻawi i ka ikehu kiʻekiʻe i ka wili ʻana, ka wikiwiki wili ʻana a me ka hoʻohana haʻahaʻa o ka ea ma muli o ke ʻano kūikawā o loko o ka hāmare DTH i hoʻolālā ʻia e like me ke kumumanaʻo wili pōhaku hou.

2. Maikaʻi ka hana a me ka lōʻihi o ka lawelawe ʻana o ka hāmare DTH ma muli o ke kiʻekiʻe o ke kiʻekiʻe o nā mea kila kila a me ka ʻenehana hana kiʻekiʻe i hoʻololi ʻia.

3. Haʻahaʻa pilikia pilikia a maʻalahi i ka mālama ʻana ma muli o ka maʻalahi, hilinaʻi a maʻalahi hoʻi e hōʻuluʻulu a wehe i ke ʻano o loko o ka hāmare.

4. He ma'alahi ka ha'alele 'ana mai ka hamare ma muli o ke kaula he nui po'o e ho'ohui ana i ka pahu a me ke kinikini o ka hāmare.
