Fluid power is a term covering both pneumatic and hydraulic power. The location of the piston versus time is simple harmonic motion, i.e. It eliminates the need for complicated systems of gears, cams, and levers. PN and HY-Series pneumatic and hydraulic scotch-yoke valve actuators have been. In addition to the type IV fluids that are currently in use, type V fluids are being developed in response to. class I fluids provide weight savings advantages versus class II. 12-2 Heating unit Container Cork Reservoir Liquid bath Thermometer Oil 60 c.c. Please contact us with any of you questions, we will arrange to have a salesman meet with you to discuss any of your questions or concerns and help to customize a system to the requirements needed for your product. The extensive use of hydraulics and pneumatics to transmit power is due to the fact that properly constructed fluid power system possesses a number of favorable characteristics. Hydraulic and Pneumatic Power Systems Chapter 12. fork lift trucks, 581 motors, 78, 514 efficiencies of, 81 versus hydraulics, 9, 10, 12 versus pneumatics, 457 electro - modulated hydraulics. An electro/pneumatic press provides for even clamping pressure distribution via air bags and such eliminates the otherwise typical opening up of a gap in the middle of a tool and related material flash issues like lost material, need for overfilling tool, rework of part, etc. Pneumatic systems are typically utilized in factories focusing on compressed air and inert gasses while hydraulic systems can be found in assembly processes and.Foot print of electric press is smaller since no hydraulic unit needed.An electric press, once programmed runs always the same, unlike again a hydraulic press that will run jerky if oil is cold or tool weight has changed.Once a tool specific program has been established it is saved and can be called up month later again without any additional new set-up, readjusting, etc required with hydraulic presses. Press cycle with platen stroke, platen tilt, speeds, acceleration and deceleration rates is programmable with electric press.No tightening of fittings, filter cleaning or oil changes typical with hydraulic presses. The electric press principle requires almost no maintenance except occasional greasing of ball screw assemblies.An electric press never leaks and never contaminates product or production environment.Holds forces A hydraulic actuator can hold force and torque constant without the pump supplying more fluid or pressure due to the incompressibility of fluids. They can produce forces 25 times greater than pneumatic cylinders of equal size, operating in pressures of up to 4,000 psi. An electric press saves on utility costs. Hydraulic actuators are robust and suited for high force applications. An electric press draws current (amps) only if press moves, where as a hydraulic unit runs all the time generating heat and noise.Electro / Pneumatic Press versus Hydraulic Press
