← TechnologyWhich outcome occurs when a hydraulic actuator operates in a closed-loop system with an undersized accumulator?
A)Actuator speed fluctuations during load changes✓
B)Increased fluid oxidation rates from high temperature
C)Premature wear of the actuator rod seals
D)System instability from fluid compressibility
💡 Explanation
When a hydraulic actuator has an undersized accumulator, pressure drops during increased load occur, causing speed fluctuations because the accumulator cannot supply sufficient fluid at a stable pressure. Therefore, speed fluctuations result, rather than oxidation, seal wear or instability, which are caused by different accumulator or hydraulic problems.
