← TechnologyWhich risk increases when a hydraulic bladder accumulator overcharges?
A)Accelerated bladder fatigue and rupture✓
B)Compromised thermal expansion coefficient
C)Reduced fluid bulk compressibility factor
D)Increased silting within servo valves
💡 Explanation
Excessive pressure causes *cyclic stress concentration* at bladder fold points, because the elastomer exceeds its fatigue limit with each cycle; therefore, rupture is more likely rather than silting or thermal issues, which are associated with contamination and volumetric expansion, not necessarily overcharging.
