FLUID/ABRASIVE JET CUTTING ARRANGEMENT

摘要

A high pressure cutting arrangement is formed by combining a liquid stream, such as water, and a slurry stream, the slurry comprising abrasive particles suspended in a liquid. Energy is supplied to the liquid stream by a first energising means, such as a constant pressure pump. Energy is supplied to the slurry stream by a second energising means, such as by a piston powered by a constant volume pump. The liquid stream and the slurry stream are combined in a cutting tool, in which the supplied energy is converted to kinetic energy to produce a combined liquid and abrasive stream at high velocity.
