Loaʻa i ka TDS Drill ka hiki ke hana i ka nui o ke ʻeli ʻana o ke ʻeli Rotary

Hoʻohana ākea ʻia ka tricone no ka ʻeli rotary, hoʻohana ʻia e huki i nā lua nui a me nā puka hana i nā lua nui, nā lua wai hāmama, ka lawe ʻana i ka ʻaila a me nā māla ʻē aʻe. Aia nā pūʻulu ʻelua o ka ʻeli rotary nui: (1) ʻoki ʻana i ka rotary e ka hoʻouka ʻana i kahi kiʻekiʻe i ka pōhaku mai ʻekolu mau cone, a (2) ʻoki rotary e ka ikaika shear mai nā ʻāpana kauō.

 

I ka hoʻokaʻa ʻana, ʻo nā ʻāpana i hoʻohana nui ʻia he ʻekolu-cone drill bits i uhi ʻia e nā niho a i ʻole nā ​​pihi e huli manuahi e like me ka planetary gear a haki i ka pōhaku i ka hoʻololi ʻia o ka ʻeli. Loaʻa i ka pahu i lalo e ke kaupaona o ka rig drill iā ia iho, a hoʻopili ʻia ka hoʻololi i ka hopena o ka paipu drill. Hāʻawi ʻia kahi hoʻohuli e kahi hydraulic a i ʻole ka uila uila, a hoʻololi pinepine ka wikiwiki i ka wikiwiki mai 50 a 120 rpm. Hoʻohana pinepine ʻia ka ea i hoʻopaʻa ʻia e hoʻokuʻu i nā ʻoki mai lalo o ka lua. ʻO ka nui o ka hakahaka ma waena o ka paipu drill a me ka paia o ka lua e pili ana i ka pīpī ʻana o nā ʻokiʻeli. ʻO kahi ʻiki loa a i ʻole kahi ākea ākea e hoʻohaʻahaʻa i ka wikiwiki o ka ʻeli.

Kūpono ka ʻeli Rotary no nā nui o ka bolua mai 203 a 445 mm i ke anawaena. I kēia manawa, ʻo ka ʻeli rotary ke ʻano nui o ka hana ma nā mines lua hāmama. ʻO kekahi o nā mea maikaʻi ʻole o nā rigs drilling rotary ʻaʻole kūpono ia no ke kalai ʻana i kahi holehole i makemake ʻia, kahi mea maikaʻi i ka puhi pōhaku.

 

E hoʻonui nui ka hama percussion i ka huahana, keu hoʻi i nā kūlana pōhaku paʻakikī. Haʻaheo mākou e ʻōlelo i ka hiki i ka BD DRILL ke hāʻawi i nā aho ʻeli rotary a pau, mai ka Shock absorb, Drill pipe, Stabilizer, Percussion hammer, Deck bush, Tricone bit.
