Rest of the Term

Today’s Lecture

• Intro to Fluid Power: An overview of fluid power systems, including the historical developments and modern applications in various industries.

• Review of Key Fluid Mechanics Concepts: Fundamental concepts such as viscosity, density, and flow characteristics will be revisited for context in subsequent applications.

• Hydraulic Applications: Exploration of the uses of hydraulic systems in machinery, manufacturing, transportation, and aerospace.

• Fittings and Hoses: Detailed examination of types and materials for hydraulic fittings and hoses, their specifications, and how they influence system performance.

• Hydraulic and Pneumatic Symbols: Introduction to common symbols used in hydraulic and pneumatic schematics for effective communication in engineering designs.

Applications

Fluid power systems are crucial in providing controlled movement and force through the use of liquids and gases, serving as an alternative to traditional mechanical and electrical systems. Hydraulic systems are particularly advantageous in applications requiring substantial force, precision, and smooth operation, such as construction equipment and automotive brakes.

Fluid Power

Fluids, whether liquids or gases, can efficiently transmit energy, which forms the cornerstone of fluid-powered systems. Common examples include:

• Water: Used in various hydraulic applications due to its availability and non-compressibility.

• Mineral Oil: A common hydraulic fluid due to its lubricating properties and suitability for high-pressure applications.

• Synthetic Oil: Engineered fluids with enhanced characteristics such as reduced flammability or improved thermal stability.

• Compressed Air, Nitrogen, Argon: Gases used in pneumatic systems, which provide flexibility and lightweight advantages but at a higher energy cost for power generation.
