1. What is the primary purpose of a hydraulic accumulator?
A. Increase flow rate
B. Store hydraulic energy
C. Reduce pressure
D. Filter contaminants
Answer: B
Rationale: Accumulators store energy in the form of pressurized fluid for
later use.
2. Which type of pump is most efficient at high pressures?
A. Gear pump
B. Vane pump
C. Piston pump
,D. Centrifugal pump
Answer: C
Rationale: Piston pumps are designed for high-pressure, high-efficiency
applications.
3. What does cavitation in a hydraulic pump cause?
A. Increased efficiency
B. Noise and damage
C. Higher pressure output
D. Reduced temperature
Answer: B
Rationale: Cavitation forms vapor bubbles that collapse and damage
internal components.
4. Which valve controls the direction of fluid flow?
A. Pressure relief valve
B. Flow control valve
C. Directional control valve
D. Check valve
Answer: C
Rationale: Directional control valves route fluid paths within the system.
,5. What is the function of a pressure relief valve?
A. Increase pressure
B. Maintain minimum pressure
C. Limit maximum pressure
D. Store pressure
Answer: C
Rationale: It protects the system from overpressure conditions.
6. What unit is used to measure hydraulic pressure?
A. PSI
B. GPM
C. RPM
D. Watts
Answer: A
Rationale: Pounds per square inch (PSI) is the standard pressure unit.
7. What is the purpose of a hydraulic filter?
A. Increase pressure
B. Remove contaminants
C. Control flow
, D. Reduce heat
Answer: B
Rationale: Filters remove particles to protect system components.
8. Which fluid property affects leakage in a hydraulic system?
A. Density
B. Viscosity
C. Temperature
D. Color
Answer: B
Rationale: Higher viscosity reduces leakage but may affect flow.
9. What type of actuator produces rotary motion?
A. Cylinder
B. Motor
C. Pump
D. Valve
Answer: B
Rationale: Hydraulic motors convert fluid power into rotary motion.
