What is a hydraulic actuator?•
What is a hydraulic actuator?
• Not much different than pneumatic actuators as discussed in Episode 66.
o Episode# 66: What is a Pneumatic Actuator? | https://www.valin.com/resources/video...
• Basic motion actuation for fluid power
• Key differences
o Pneumatics use air. Hydraulics use liquid.
- Devon Hyatt, specialist in fluid power, expands on the differences
• Air is compressible. Liquids are not.
• Results in higher forces from hydraulics
o Do hydraulic actuators also have single-acting and double-acting options?
- Yes, Devon Hyatt explains further.
o Do hydraulic actuator types also include rod, rod-less, rotary and gripper?
- Devon explains that, while there isn’t really a rod-less type, there are many different types
o Are there also ISO and NFPA versions of hydraulic actuators?
- Yes
o What are open versus closed-loop hydraulic systems?
- Open-loop systems take liquid from and return it to a reservoir with a breather
- Closed-loop systems uses a recirculation pump instead while containing the liquid entirely within it and the hoses going to the actuator
• When would I use hydraulics over pneumatics?
o To insure constant force
o To produce higher forces
o To absorb higher vibration or shock loads
• System Components needed to move a hydraulic actuator
o Provide liquid flow
- Engine or motor plus a pump
o Control the liquid to the actuators
- Valves and flow controls
o Make sure the liquid is clean
- Filter and regulate
• Pros of hydraulic actuators
o High force-to-size ratio
o Shock absorbent
o Great for mobile equipment
o Simplicity
• Cons of hydraulic actuators
o Components wear out making for short life cycles
o Fluid quality maintenance
o Low efficiency
o Leaks are messy
o Low accuracy
o Limited cylinder positions
