PRESSURE INTENSIFIER BASED ON THE CONCEPT OF A ROTARY FLOW DIVIDER

Abstract

Pressure intensifiers are used in specific areas of a hydraulic circuits, where increased pressure is needed, while the rest of the circuit (up to the pump) run on lower level of a working pressure. That could lead to a cheaper design of the components, while just one high pressure branch is designed on high pressure. Using pressure intensifier could also mean energy cost reductions. Rotary flow divider can be also used as a pressure intensifier. This area started to be developed in Jihostroj a.s. This paper describes specific tests, which has been running to precisely parameterize limits of use of a divider as an intensifier without design changes to follow with a development of a designs to maximize intensifier’s parameters. Development also leads to compact solutions compatible with LS signals or with other hydraulic components to create compact assembly comparable to some areas of use of a piston pumps or inexpensive flow control drive. These development opportunities are also described in this paper.
