← TechnologyWhich consequence results when excessive 'hunting' occurs within a proportional valve controlled hydraulic actuator?
A)Decreased actuator lifespan✓
B)Increased fluid temperature
C)Higher energy efficiency
D)Improved control precision
💡 Explanation
Excessive hunting induces fluctuating pressure because dithering reduces static friction within the valve, causing oscillations. Therefore, mechanical stress on the actuator seals and components raises exponentially, leading to premature pump failure and reduced lifespan, rather than increased hydraulic precision.
