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

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

Hoʻohana ʻia nā niho bakeke no ka ʻoki ʻana a me ka ʻeli ʻana, a ua hoʻohana ʻia nā bākeke hoʻopakele ʻelua ma lalo me nā paipu friction drill e wili i nā ʻano paʻa me ka haʻahaʻa haʻahaʻa, e like me nā papa lepo, nā ʻili lepo a me nā papa one me ka ikaika geological maʻamau i loko o 400 kPa, ma o nā niho bakeke. ʻO ka ʻoki ʻana i ka Rotary e hōʻemi i ka huki ʻana a hoʻonui i ka wikiwiki o ka rig. ʻO Madagascar 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 ʻana i ka paipu e like me ka ikaika geological, a hiki ke wili i ka ʻiliʻili, ka ʻalae, ke one, Shale a me ke anuanu. , etc., ma o ka hoʻoneʻe ʻana i ke kaomi ʻana i ka helu alloy ma ke koho e hoʻokō i ka wili ʻana.

ʻEkolu, hoʻololi

Hiki ke hoʻohana ʻia me ke one lua lalo a me nā bākeke wili 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 ʻoki ʻana, hiki ke wili ʻia me ke ʻano ʻano toggle, 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 ʻano hana e pale aku i ka ikaika a me ka haʻalulu o ka pebble.Madagascar Excavator sprocket

4. ʻAno wili:

Ma ka hoʻohana ʻana i ka drill pōhaku a me ka drill shaft niho, me ka paipu drill laka mīkini e wili ai i loko o ka hoʻokumu pōhaku i helu ʻia e ka ikaika compressive pōʻai hoʻokahi, ʻo ka ikaika mai kahi MPa a i mau ʻumi MPa, maʻamau ka hopena o ka pōhaku. pile, ma o ka barela drill Okipoepoe a wili i loko o ka pōhaku, a wili a me ka wili ʻana ma o ka wili niho niho, i ka manawa like, e like me ke ʻano, ikaika, brittleness a me ka māwae o ka hoʻokumu pōhaku, ʻaʻole i kāpae ʻia ka hiki o ka fragmentation. .Madagascar Excavator sprocket
