Study Notes
Differences Between Hydraulic and Pneumatic Systems
- Fluid Medium: Hydraulic systems use incompressible liquids (usually oil) for power transmission, while pneumatic systems utilize compressible gases (commonly air).
- Pressure Range: Hydraulic systems operate at higher pressure levels, often exceeding several thousand psi, whereas pneumatic systems typically function around 100-120 psi.
Leakage Issues
- Proneness to Leakage: Hydraulic systems are more prone to leakage due to the nature of liquid containment, which is affected by seals and fittings. Pneumatic systems face less leakage risk as they deal with gas, which can dissipate more easily.
Advantages of Pneumatic Systems
- Applications Benefit: Pneumatic systems provide faster response times and lighter weight, making them advantageous for applications requiring quick actuation and maneuverability.
Common Issues in Systems
- System Failures: Both hydraulic and pneumatic systems can face issues such as pressure loss and contamination, potentially leading to ineffective operation or damage.
Disadvantages of Pneumatic Systems
- Force Limitations: Pneumatic systems often deliver less force compared to hydraulic systems, which can limit their efficacy in heavy-duty applications.
Compressibility Factor
- Significant Impact: The compressibility of gases in pneumatic systems is a crucial factor affecting performance, making control and predictability more complex than in hydraulic systems.
