I-Polycrystalline Diamond Carbide Faka Ibhithi Yenkinobho Ye-PDC ye-DTH
Chofoza Engeziwe
I-Polycrystalline Diamond (PCD) iyidayimane yokwenziwa. Ithuluzi le-PCD linikeza ukumelana nokugqokwa okuphezulu ezintweni eziqhuma kakhulu.
I-PCD Carbide yokufaka inkinobho kancane siyibiza nge-PDC Button Bit, evame ukusetshenziselwa i-DTH Bit, i-RC Bit, i-Top Hammer Bit. Lezo zingcezu zisetshenziselwa ukumba amatshe, izimayini kanye nokuhlola umhlaba.
Kukhona enye i-Polycrystalline Diamond Compact bit nayo ebizwa nge-PDC Bit enamaphiko angu-3-7 embonini kawoyela negesi. Kodwa akusikho esikhuluma lapha.
Ibhithi ye-PDC ene-PCD carbide inesikhathi eside sokusebenza isikhathi eside kune-tungsten carbide bit, okungukuthi, cishe isikhathi esingu-5-7 isikhathi eside sokuphila. Ngakho liya ngokuya lidume kakhulu endaweni yokusebenza yezimayini.
