← TechnologyWhich impairment reduces power when a hydraulic actuator rapidly cycles?
A)Cavitation erodes valve seats✓
B)Viscosity reduces fluid movement
C)Stiction increases piston displacement
D)Creep enlarges cylinder bore
💡 Explanation
Cavitation causes surface damage via imploding vapor bubbles. Therefore, pump efficiency decreases because metal erodes due to repeated implosions; rather than momentary issues from viscosity, valve stiction, or creep which causes constant rather than intermittent output impairment.
