Development of Phased Intensifier for Waterjet Cutting

Abstract

The paper describes a significant advance in ultra-high pressure waterjet cutting technology through the development of the phased intensifier. In a phased intensifier, as opposed to a standard double-acting intensifier, piston-plunger assemblies in varous cylinders are independently controlled in such a way as to theoretically produce an uninterrupted, perfectly uniform pressure signal. The quality of signal does not depend on the size or location of an accumulator, as in a double- acting intensifier. The phased concept offers many other advantages: a compact, economical design with much smaller footprint and integrated packaging; much enhanced reliablity of hydraulic and high-pressure components due to slower cycling; better suction capability; easier installation. The paper explains the concept and outlines the basis of its many advantages.
