- Provides a cushion against pressure surges
- Compensates for leaks or changes in fluid volume
2. Describe the operating principle of a hydraulic pump.
Positive Displacement Pumps
- Traps fluid in a fixed volume and displaces it through a system
- Types include gear pumps, vane pumps, and piston pumps
Centrifugal Pumps
- Uses rotating vanes to impart velocity to the fluid
- Converts kinetic energy into pressure
3. What are the different types of hydraulic valves and their functions?
- Check valves: Allow flow in one direction only
- Relief valves: Limit system pressure by diverting excess flow
- Directional valves: Control the direction of fluid flow
- Pressure reducing valves: Reduce system pressure to a lower value
- Flow control valves: Regulate the flow rate of fluid
4. How do you troubleshoot a hydraulic system that is experiencing excessive heat?
Check for:- Clogged filters or lines
- Loose or leaking connections
- Worn or damaged components
- Overloading or improper system design
5. What are the safety precautions to observe when working with hydraulic systems?

- Visualize the system’s operation
8. What are the different types of hydraulic hoses and fittings and their applications?
- Thermoplastic hoses: Flexible and resistant to high pressures
- Rubber hoses: Durable and suitable for heavy-duty applications
- Metal hoses: Strong and long-lasting, but less flexible
- Fittings: Connect hoses to components and secure fluid flow
9. How do you maintain and repair hydraulic systems to ensure optimal performance?
- Regular oil changes and filter replacements
- Inspection of hoses, lines, and seals for leaks or damage
- Calibration of valves and sensors
- Troubleshooting and repair of faulty components
- Regular cleaning and lubrication
10. Describe the principles of fluid power and how they apply to hydraulic systems.
- Pascal’s law: Pressure applied to a fluid is transmitted equally in all directions
- Bernoulli’s equation: Velocity and pressure are inversely related in a flowing fluid
- Conservation of energy: Energy cannot be created or destroyed, only transferred
