I need some direction in picking a component set for a hydraulic rig I want to build. I am upgrading my existing hand jack setup (which is great for static forces) to something with active controls and the ability to cycle pressure.
It needs this functionality: Pressurize hydraulic cylinder to 4000 psi for x minutes, then ramp down to 3000 psi (no time requirement), hold for x minutes, then ramp up to 4000 psi, over and over. I have a full data acquisition I/O system at my disposal for control signals, transducer output etc.
I’ve done something similar with pneumatics, but I had easy access line pressure, a 2 way cylinder and solenoid valve. Rejecting air to the room was easy. It seems like a similar approach with hydraulics, but made complicated by the fluids involved. Would I need a hydraulic accumulator?
