Tricone me ntsis yog dav siv rau kev teb drilling, feem ntau yog siv los laum qhov loj thiab qhov ntau lawm hauv cov chaw txua txiag zeb loj, qhib qhov mines, roj av extraction, thiab lwm yam.Muaj ob pawg loj rotary drilling: (1) rotary crushing los ntawm high-point loading rau lub pob zeb los ntawm peb lub cones, thiab (2) rotary txiav los ntawm shear quab yuam los ntawm cov khoom siv.
Hauv rotary crushing, cov khoom siv dav siv yog peb-cone laum cov khoom siv los ntawm ntau cov hniav lossis cov nyees khawm uas tig ywj siab zoo li cov iav planetary thiab tsoo lub pob zeb raws li cov laum me ntsis tig.Lub downward thrust yog ua tiav los ntawm qhov hnyav ntawm lub laum rig nws tus kheej, thiab kev sib hloov yog siv rau qhov kawg ntawm lub laum yeeb nkab.Kev sib hloov yog muab los ntawm hydraulic lossis lub tshuab hluav taws xob, thiab kev sib hloov ceev feem ntau txawv ntawm 50 txog 120 rpm.Compressed cua feem ntau yog siv los tso cov txiav tawm hauv qab ntawm lub qhov.Qhov luaj li cas ntawm qhov sib txawv ntawm cov yeeb nkab laum thiab phab ntsa ntawm lub qhov yog cuam tshuam nrog cov dej ntws ntawm cov laum txiav.Txawm tias qhov nqaim dhau los yog qhov sib txawv dhau lawm yuav txo qis qhov drilling ceev.
Rotary drilling yog tsim rau qhov loj me ntawm 203 mus rau 445 hli inch.Txog tam sim no, rotary drilling tau yog txoj hauv kev tseem ceeb hauv qhov qhib qhov av loj.Ib qho ntawm qhov tsis zoo ntawm cov teb drilling rigs yog tias lawv tsis haum rau drilling qhov inclined borehole, uas yog qhov zoo rau pob zeb blasting.
Tricone percussion rauj yuav ua rau kom cov khoom tsim tau ntau, tshwj xeeb tshaj yog nyob rau hauv cov pob zeb nyuaj.Peb txaus siab hais tias BD DRILL muaj peev xwm muab tag nrho cov kev sib hloov drilling hlua, los ntawm Shock absorb, Laum yeeb nkab, Stabilizer, Percussion rauj, Deck hav txwv yeem, Tricone ntsis.
