← TechnologyWhich risk increases when a hydraulic actuator lacks proportional control during high-speed extension?
A)Pressure-wave induced pipe fracture✓
B)Thermal runaway in the oil
C)Decreased response actuator precision
D)Rotor bearing wear increases rapidly
💡 Explanation
A lack of proportional control in a hydraulic actuator can lead to pressure transients amplified throughout the system via hydraulic resonance, because the sudden valve closure induces amplified pressure-wave oscillation. Therefore, pipe fracture is a risk, rather than mere precision loss under ideal control.
