← TechnologyWhich outcome occurs when temperature increases rapidly within a pneumatic actuator?
A)Reduced output force, unpredictable positioning✓
B)Increased lubricant viscosity, smoother motion
C)Decreased seal swelling, reduced friction
D)Enhanced corrosion resistance, longer lifespan
💡 Explanation
Increased temperature will affect the gas in the actuator, making it decrease its efficiency; this is because thermal expansion causes pressure variations influencing precision. The mechanism is thermal-pressure derating, therefore force decreases, rather than improvement in lubrication due to viscosity.
