HYDRAULIC SYSTEM
7.1 Overview
The main hydraulic power circuit supplies the intensifier assembly with the hydraulic oil required
to produce high pressure water. High pressure cutting water is generated from the oil pressure in
the hydraulic cylinder.
System components include the electric motor, hydraulic pump, 4-way directional control valve
and the hydraulic manifold. The manifold houses the high and low pressure control valves,
hydraulic gauge, two pressure solenoid valve and the main system relief valve. The system relief
valve monitors hydraulic oil pressure and provides system protection by limiting excess pressure.
