Aims & Learning Objectives:
To enable the student to appreciate the factors which influence the specification and performance of hydraulic components. To provide guidance in their selection and the basis for the sizing of actuators, valves, pumps, motors, filters, accumulators, and associated equipment with the requirements of the load and duty cycle in mind.
After taking this unit the student should be able to:
select a satisfactory supply system for low energy loss and noise levels with good controllability and give an understanding of the factors affecting overall system performance by examining interactions between system components.
Content:
Actuator Systems: Flow considerations, Pressure losses, Valve flow characteristics.
Supply Systems: Sizing of accumulators, Selection of heat exchangers.
Rotating Systems: Pump and motor characteristics, Hydrostatic transmissions.
Noise and Vibration: Sources of noise in hydraulic system. Methods of noise and vibration reduction.
Fluid Management: Classification of contamination levels, Filters and their selection, Fluid sampling techniques.
