I-Polycrystalline Diamond Carbide Faka i-PDC Bit yeqhosha le-DTH

Idayimani yePolycrystalline (PCD) yidayimani yokwenziwa. Isixhobo se-PCD sibonelela ngokumelana nokunxiba okuphezulu kwizinto ezirhabaxa kakhulu.
I-PCD Carbide faka iqhosha elincinci silibiza ngokuba yi-PDC Button Bit, edla ngokusetyenziselwa i-DTH Bit, i-RC Bit, i-Top Hammer Bit. Loo masuntswana asetyenziselwa ukwembiwa kwamatye, imigodi kunye nokuhlola umhlaba.
Kukho enye i-Polycrystalline Diamond Compact bit ebizwa ngokuba yi-PDC Bit enamaphiko angama-3-7 kwishishini leoli kunye negesi. Kodwa asiyiyo le siyithethayo apha.
I-PDC bit ene-PCD carbide inobomi obude kakhulu bokukhonza kune-tungsten carbide bit, okt, malunga ne-5-7 ixesha elide lobomi. Yiyo ke loo nto isiya isaziwa ngakumbi kwindawo yokusebenzela yemigodi.
Iimpawu ze-DTH bits:
