Introduction

  • Humans have always needed to move and lift heavy objects.

Power Transmitting

  • All machines require a power source and a method to transmit it.
  • Power transmission methods include mechanical, electrical, and fluid power.

What is Fluid Power?

  • Fluid power is using pressurized fluid to generate, control, and transmit energy.
  • Hydraulics and pneumatics are two common types.
  • Hydraulics uses liquids (typically oil).
  • Pneumatics uses gases (typically air).

Concepts of Fluid Power

  • Fluid power systems are classified into hydraulics and pneumatics.
  • Hydraulics studies liquid movement applications. Oil is the common medium.
  • Pneumatics studies gas/air movement applications. Air is the common medium.

Concepts in Fluid Power

  • Pumps are the heart of hydraulic systems.
  • Compressors are the heart of pneumatic systems.
  • Both are powered by prime movers (mostly electric motors or combustion engines).
  • These convert mechanical energy into fluid or pressure energy.

Fluid Systems

  • Fluid transport systems move fluid from one location to another (e.g., pipelines, pumping stations).
  • Fluid power systems use fluid to perform work.

Examples of Fluid Power Systems

  • Hydraulic jacks
  • Vehicle brakes
  • Landing gear systems

Fluid Power System

  • A hydraulic system uses a prime mover to drive a pump, pushing fluid through lines to an actuator.
  • The actuator then executes the work.

Functions of Fluid Power Systems

  • Energy conversion
  • Fluid distribution
  • Fluid control
  • Work performance
  • Fluid maintenance

Hydraulic verses Pneumatic Systems

  • Hydraulic systems use high pressure, are slow, and more costly but are more accurate.
  • Pneumatic systems use lower pressure, are faster, and less costly.

Advantages of Fluid Power Systems

  • Easy control of force, torque, speed, power and actuators movements

Basic Fluid Power System Components

  • Power unit group: prime movers (e.g., electric motors, internal combustion engines), pumps/compressors, reservoirs/receivers
  • Actuators group: cylinders, motors
  • Conductors group: pipes, tubes, hoses
  • Control valves group: directional control valves, pressure control valves, flow control valves
  • Fluid maintenance group: filters, separators, lubricators

Hydraulic System Operation:

  • Oil movement initiates at the pump.
  • Low inlet pressure causes oil to filter through the system, leading to high pressure at the outlet.
  • The high pressure then forces the oil through control valves to the actuators (cylinders or motors) to accomplish the required work.
  • The used oil is returned to the reservoir for recirculation.

Application of Fluid Power

  • Industrial machinery (injection molding, presses)
  • Factory automation (robotic systems)
  • Oil drilling
  • Construction equipment (excavating machines, rollers)
  • Agricultural equipment (tractors, harvesters)
  • Amusement rides (themed parks)
  • Aerospace (some aircraft systems)
