SYSTEM, APPARATUS AND METHOD FOR ABRASIVE JET FLUID CUTTING

摘要

A system, apparatus and method for abrasive jet fluid cutting. An abrasive jet fluid cutting nozzle assembly comprises a hose 49 for receiving an abrasive jet cutting fluid; a helix/spring 40 rotatably attached inside the high pressure hose 49 ; and a nozzle 46 connected to the hose 49 . The helix/spring 40 is tapered such that the turn ratio of the helix 40 varies from the proximate end to the distal end. The rotation of the helix 40 creates a vortex and increases the pressure of an abrasive jet cutting fluid as it passes from the proximate end to the distal end. The disclosed subject matter further includes a system and method for using the abrasive jet fluid cutting nozzle assembly.
