Tungsten Carbide Pulsed Nozzle Drilling Principle

When drilling, owing to the drilling machine and rock crushing separating the cuttings often pressed at the bottom by huge pressure differential, which also known as "cuttings hold effect." And this effect is easy to form large clumps of plastic so as to form a layer of "cushion" between the drill bits and inside rocks. Therefore, the drilling speed is decreasing and the abrasion of drilling bit is accelerating. The most significant part of drilling is hydraulic power and the spray drilling takes full advantage of this for cleaning and rock breaking. The related statistics show that tungsten carbide pulsed nozzle prompt energy is 1.5 times bigger than normal nozzle, and effective distance is improved so that the pressure is distributing more reasonable, and the efficiency is enhanced.
