HOW DO ACTUATOR CHOICES AFFECT PRODUCTIVITY IN MOTION-CENTRIC AUTOMATION ENVIRONMENTS?
Pneumatic actuators are available in a variety of shapes, sizes, and types, as well as with a multitude of standard options. At first glance, the number of permutations can be overwhelming. The good news is that each actuator type and configuration has a place in today's automation environment.
Pneumatic actuators are selected by their ability to do work and the most common factor that limits productivity is using an undersized actuator. Follow these tips to the right actuator for the job:
Determine the force.
Subtract the piston rod area, if applicable.
Know the true operating pressure.
Allow for internal actuator friction, i.e. seals, bushings, and wear bands.
Know the true load.
Factor in speed requirements.
Consider the angles.
Design in a margin, anticipating demand for future productivity improvements.
Consider kinetic energy.
