Product Detail

Khoom cim npe

Down-the-hole laum khoom, tseem hu uadth ualaum khoom, txuas nrog rau rauj los ntawm kev xyaum me ntsis lub cev spline, uas coj thiab xa cov kev sib hloov rau rauj. Lub laum me ntsis thiab rauj dhia mus rau hauv lub qhov kom tawg lub pob zeb. Down-lub-qhov laum cov khoom muaj xws li high-pressure down-the-hole laum khoom, nruab nrab- thiab qis-siab down-lub-qhov laum khoom.

Daim ntawv thov:

DTH laum khoom yog siv rau hauv qhov loj-loj qhib-qhov thiab hauv av ore mining, consolidation engineering, quarrying thiab pob zeb drilling, tsim engineering pob zeb drilling, dej zoo drilling, thiab loj-scale engineering siv. Nws muaj qhov zoo ntawm qhov siab flatness, du lub qhov phab ntsa, siab nruj ntawm laum pas nrig thiab rauj, ywj siab ntawm siab axial thrust, tsis muaj kev txwv ntawm drilling qhov tob, tsis tshua muaj nqi ntawm cov cuab yeej thiab yooj yim rau maintain

Qhov zoo ntawm Cov Cua Kub Siab DTH Bit:

1. Cemented carbide nyees khawm
2. Cov dej ntws zoo heev
3. Spherical, ballistic, parabolic inserts
4. lub neej ntev

Nta:

1. Kev ntseeg tau zoo nrog kev ua haujlwm ruaj khov
2. Cov khoom siv nruj nruj xaiv ua kom lub neej ua haujlwm ntev
3. Cov nyhuv flushing zoo nce qhov drilling tus nqi
