Pono ke kelepona paʻalima e ʻike! ʻO ka hoʻolauna ʻana i nā ʻano hana wili like ʻole o ka rotary drilling rig.Nigeria Excavator sprocket

Pono e ʻike mau ka mea hoʻohana o ka wili wiliwili i ke ʻano a me ka ikaika o ka geology e wili ʻia i kēia manawa, a me ke ʻano o ka paipu wili a me ka mea hana wili e pono ai ke hoʻohana ʻia, a he aha ke ʻano o ka wili ʻana e pono ai, a ma kēia ala wale nō e hiki ai ke hoʻomalu maikaʻi ʻia. ʻO ka hana, nā haʻahaʻa haʻahaʻa, ka lole haʻahaʻa a me ka wikiwiki o ka footage.Nigeria Excavator sprocket

Hiki ke hoʻokaʻawale ʻia nā rig drilling Rotary i ʻehā mau ʻano wili e like me nā kūlana geological: ʻoki, ʻokiʻoki, ʻohi a me ka wili.

1. ʻAno ʻoki:

Hoʻohana ʻia nā niho bakeke no ka ʻoki ʻana a me ka ʻeli ʻana, a hoʻohana ʻia nā bākeke salvage lalo ʻelua me nā paipu drill friction no ka wili ʻana i nā ʻano paʻa me ka haʻahaʻa haʻahaʻa, e like me nā papa lepo, lepo a me nā papa one me ka ikaika geological maʻamau i loko o 400 kPa, ma o nā niho bakeke e hōʻemi ana i ka huki ʻana a hoʻonui i ka rig speed.Nigeria Excavator sprocket.

2. ʻAno haʻihaʻi:

Ke hoʻohana nei ka ʻeli ʻana i ka wili koho, ʻo ka hapa nui o ia mau mea e hoʻohana i nā bākeke wili pōhaku lua-lalo, a hiki ke hoʻolako ʻia me ka friction resistance a i ʻole ka mīkini paʻa paʻa paipu drill e like me ka ikaika geological, a hiki ke wili i ka ʻiliʻili, pōhaku lepo, one, Shale and medium weathering, etc.

3. Hoʻololi

Hiki ke hoʻohana ʻia me ke one lua lalo a me nā bākeke lua lalo, a hiki ke hoʻohana pū ʻia me nā niho Bauer. Ma muli o nā ʻano ʻano geology, e loli ke ʻano o ka wili ʻana. No ka ʻohi ʻana, hiki ke wili ʻia me kahi ʻano hoʻololi, ua kau ʻia ka paipu drill me ka wili nui, hoʻopili ʻia ka ʻiliʻili me ka piko o ka niho o ka pahu drill, a wehe ʻia ka ʻiliʻili a lana ka pahu drill i lalo. ʻO kēia kaʻina hana e pale aku i ka ikaika a me ka haʻalulu o ka pebble.Nigeria Excavator sprocket

4. ʻAno wili:

Ke hoʻohana nei i ka wili pōhaku a me ka puʻu niho niho, me ka paipu wili mīkini paʻa e wili ai i loko o ka pōhaku i helu ʻia e ka ikaika compressive hoʻokahi, ʻo ka ikaika mai kekahi MPa a hiki i nā ʻumi MPa, ʻo ka maʻamau o ka puʻu hopena pōhaku, ma o ka pahu drill ʻoki poepoe ʻana a wili i loko o ka pōhaku, a i ʻole ka wili ʻana a me ka ʻeli ʻana ma ke kumu o ka niho niho, i ka manawa like, ka ikaika a me ka ikaika, e like me ke ʻano o ka puʻupuʻu, ka ikaika a me ka ikaika o ka pōhaku. ʻAʻole i hoʻokaʻawale ʻia ka hiki ʻana o ka ʻāpana.Nigeria Excavator sprocket
