ʻElua ʻano ʻano: ʻo kekahi i loko o ka rotary rotary drilling rig ma ke kumu o ka hoʻohui ʻana i ka mīkini hopena, ka mea nui i ka rotary drilling, i ka wā e hālāwai ai i ka papa ʻiliʻili me ka hopena wili lua-purpose well drilling rig, ikaika hiki ke hoʻololi i nā strata like ʻole;ʻO ka mea ʻē aʻe ka hopena a me ka hana rotary i hui pū ʻia me ka rig drilling well, e like me ka pneumatic DTH hammer drill.ʻO ka DTH hammer drill (FIG. 5) i haku ʻia me kahi liner cylinder a me kahi piston e neʻe i luna a i lalo i loko o ka liner cylinder.Hoʻopili ʻia ka ʻaoʻao haʻahaʻa o ka liner cylinder me ka drill bit, a ʻo ka ʻaoʻao luna e hoʻopili ʻia me ka pipe drill ma o ka hui wili.ʻO ka ea kiʻekiʻe i hāʻawi ʻia e ka mea hoʻoheheʻe ea he 0.7 ~ 1.4 mpa ma o ka pahu pahu ma luna o ka piston, ka mea hoʻolaha ea a me ka ea inlet ma lalo o ka piston, a ʻo ka hopena pinepine o ka piston e hoʻokuʻu ʻia i luna a i lalo e like me 700 ~ 1200 manawa/min, no laila e pā pinepine ka piston i ka bit drill.No ka hoʻonui i ka hiki o ka drill bit e wili pōhaku.I ka manawa like, huli ka paipu drill ma kahi haʻahaʻa haʻahaʻa o 35 ~ 60 RPM.Kahe ka ea mai ka lua o luna a lalo o ka piston i ka bit e hooluolu i ka bit a lawe mai i na oki puka lalo mai ke poo luawai.ʻO ke ʻano o ka ʻāpana holoi holoi maikaʻi a me ka ʻāpana o ka rotary rotary drill me ka ea paʻa, a ʻo ka bit i hoʻohana ʻia ʻo tungsten carbide ball tooth bit a i ʻole roller cone bit.Hiki ke hoʻohana ʻia ka hammer drill Pneumatic DTH no ka ʻeli ʻana i nā luawai hohonu ma nā ʻāpana pōhaku paʻa.He kiʻekiʻe ka wikiwiki o ka wili ʻana, a ʻaʻole i emi ka wikiwiki o ka wili ʻana ma muli o ka piʻi ʻana o ka hohonu o ka wili ʻana, a pololei ka lua wili.

I mea e hoʻololi ai i nā pono o nā strata drilling like ʻole, hoʻomaikaʻi i ka hana hoʻoheheʻe ʻana, ʻo ka lua drilling rig he multi-purpose drilling rig a me ka hoʻoili hydraulic piha a me ka mana o ke kuhikuhi o ka hoʻomohala ʻana: ʻo ia hoʻi, kahi drilling rig me nā ʻano mea like ʻole a me nā lako. , hiki ke hoʻohana i ka hopena, rotary a me DTH hammer a me nā ʻano hana wili ʻē aʻe;Hiki ke hoʻohana ʻia ka holoi ʻana i ka luawai, ka holoi ʻana i ka ea i hoʻopaʻa ʻia a me ka holoi maikaʻi a hoʻohuli ʻia.
