Unit Description and General Aims

A deep knowledge of hydraulics and/or pneumatics (H/P) is vital for design of efficient hydraulic and pneumatic systems (including individual machines), maintenance and trouble-shooting. The student will gain a working knowledge of how to apply H/P to achieve desired outcomes. This unit will focus on a range of varied circuit configurations including components controlling both fluid pressure and flow. Furthermore, a good working knowledge of other items that makes up a circuit, such as, actuators: both linear (cylinders) and rotary (motors). The student will be able to apply electro-hydraulic technology, both proportional- and servo-motor types.
The student will learn to apply knowledge gained of hydrostatics and fluid flow theory to calculate circuit requirements such as load capacity, pipe sizes, heat generation and input power. This topic will also deal with correct system installation, how to achieve reliability in operation and trouble shooting of complete systems.
Topics on the social, economic and environmental issues arising from the implementation of H/P systems, especially when coupled with robotics and mechatronics will be evaluated. A well-proven PC based program will enable the student to design and test their own circuit designs. The Karnaugh mapping method will enable students to minimise the number of components in a circuit to achieve desired outcomes.

Learning Outcomes

On successful completion of this Unit, students are expected to be able to:

  1. Determine the economics, and other factors for an application, to utilise an industrial H/P system in preference to other systems and to delineate which system is best.

  2. Evaluate in detail what discrete components make up an H/P system.
    • Bloom’s Level 5
  3. Judge, critique information on optimal design, operation, troubleshooting and maintenance of H/P systems.
    • Bloom’s Level 5
  4. Formulate on the social, commercial and regulatory impacts of installing or modifying H/P systems.

  5. Evaluate existing or propose new applications for industrial H/P systems.
    • Bloom’s Level 5
  6. Reassemble design information of a system to satisfy end-user requirements
    • Bloom’s Level 6
