Iithegi zeMveliso

Imibhobho yokubhobhoza esetyenziswa kwizicelo ezifana ne-DTH/ DTHR/ DR ngokusisiseko ibandakanya umbhobho wentsimbi onephini kwelinye icala kunye nebhokisi kwelinye.Umsebenzi wombhobho wokubhobhoza kukuhambisa itorque ejikelezayo kunye nokutyhala ukusuka kwi-drill rig ejikelezayo yentloko ukuya kwizixhobo zokomba ezisezantsi.

Ngokwesicelo esahlukileyo, ii-diameters ezahlukeneyo zeetyhubhu zokubhobhoza ziyafuneka, ngokusisiseko, ii-hammers ze-DTH ezincinci zifuna iibhubhu ezincinci ze-DTH zokuqhuba, ngokuchaseneyo.Ngokwesiqhelo sinika i50mm, 60mm, 76mm, 89mm, 95mm, 102mm, 114mm, 127mm, 140mm, 159mm.

Ngokuqhelekileyo imisonto ludibaniso oluqhelekileyo lwe-API, njenge-2 3/8″ i-API REG intambo, 3 1/2″ i-API REG intambo okanye i-API IF intambo, njl.
Ngokwesicelo sabathengi, ukusuka kwi-1000mm ukuya kwi-6000mm ubude bombhobho ziyafumaneka.
