← TechnologyWhich risk increases greatly when sizing an accumulator for a hydraulic surge-suppression system?
A)Overshoot oscillations after valve closure✓
B)Thermal expansion causing volume loss
C)Increased settling time of pressures
D)Seal degradation from fluid stiction
💡 Explanation
Overshoot becomes problematic because undersized accumulators engage in greater oscillation following a surge event due to insufficient damping through fluid compressibility stabilizing control; therefore, increased, continued systemic instability follows rather than mitigated forces, steady equilibrium or elastomer compromise.
