← TechnologyWhich risk increases when a hydraulic actuator suddenly stops rapidly due to cavitation?
A)Contaminant ingress due to vacuum
B)Bearing wear from prolonged lubricant starvation
C)Overpressure spike damaging downstream components✓
D)Reduced bulk modulus due to fluid aeration
💡 Explanation
When a hydraulic actuator stops suddenly from cavitation, the imploding voids quickly decelerate fluid creating a pressure surge because momentum transfers causing a damaging overpressure spike. Thus risks increased pressure impacting downstream components, rather than ingress, wear, or aeration which occur through unrelated processes.
