Polycrystalline Diamond Carbide Ikani PDC Button Bit kwa DTH
CLICK_ENLARGE
Polycrystalline Diamondi (PCD) ndi diamondi yopanga. Chida cha PCD chimapereka kukana kwamphamvu kwambiri pazida zowononga kwambiri.
PCD Carbide yoyika batani pang'ono timayitcha PDC Button Bit, yomwe nthawi zambiri imagwiritsidwa ntchito pa DTH Bit, RC Bit, Top Hammer Bit. Zidutswazi zimagwiritsidwa ntchito kukumba miyala, migodi ndi kufufuza kwa geological.
Palinso Polycrystalline Diamond Compact bit yomwe imatchedwanso PDC Bit yokhala ndi mapiko 3-7 amakampani amafuta ndi gasi. Koma si ife tikuyankhula pano.
Ping'ono ya PDC yokhala ndi PCD carbide imakhala ndi nthawi yayitali kwambiri kuposa tungsten carbide bit, mwachitsanzo, pafupifupi 5-7 nthawi yayitali ya moyo. Chifukwa chake, ikuchulukirachulukirachulukira kuchulukirachulukira pantchito yamigodi.
