Which risk increases when a hydraulic actuator rapidly cycles with insufficient pre-charge in the accumulator?

💡 Explanation

When the accumulator's pre-charge is insufficient and the actuator cycles rapidly, pressure fluctuations induce cavitation because the fluid's vapor pressure is reached during expansion phases, causing vapour bubbles to form and collapse within the actuator. Therefore cavitation damage results, rather than fluid overheating or lower response time, both require steady flow or different failure modes to activate.
