Kev Taw Qhia General:
DTH laum rods (tseem hu ua laum raj lossis laum kav) yog lub tshuab xa cov kev cuam tshuam thiab kev sib hloov torque rau DTH rauj thiab cov khoom, nrog rau kev xa tawm rau huab cua ntws.
Raws li txoj cai, tus pas nrig sib zog yog, qhov zoo dua rau kev ua haujlwm drilling. Yog li ib lub thinner ib txwm nyiam dua ib qho thicker yog tias lwm qhov tsis zoo ib yam. Thaum lub sijhawm nruab nrab, lub zog tawm los thiab lub zog tensile yuav tsum raug coj mus rau hauv tus account, uas txhais tau hais tias tus pas nrig phab ntsa tuab yuav xav tau kom tau txais lub zog txaus. Tau kawg, thaum lub thickness yog nruj nreem thov kom nyias raws li qhov ua tau kom txo qis txoj hlua tho qhov hnyav, kuj tseem muaj lwm txoj hauv kev kom tau txais qhov zoo tshaj plaws laum raj uas siv cov qib zoo steel.
Plato muaj DTH laum pas nrig nrog ntau qhov sib txawv thickness tsim rau txhua txoj kab uas hla, ua los ntawm qib sib txawv steels rau xaiv. Yog li, nyob rau hauv kev xyaum ntawm lub teb drilling, nyob rau hauv sib txawv mob, tej zaum yuav xav tau ntau yam ntawm xyaum rods rau tej daim ntawv thov. Piv txwv li, cov tuab tuab nrog cov qib siab zoo steel rau drilling qhov nruab nrab qhov tob, xws li blasting qhov; thiab cov nyias nyias nrog qib zoo hlau rau drilling qhov tob heev, xws li drilling rau hauv av thermal. Tsis tas li ntawd, Plato DTH laum rods kuj tau zoo thaum tshav kub kub kho, precision tsim, thiab kev sib txhuam-welded.
