Aims & Learning Objectives:
To provide familiarisation with fluid power circuits in a practical way by introducing the participants to the main hydraulic components, their performance characteristics and the standard symbols used for their representation on circuit diagrams. After taking this unit the student should be able to: read circuit diagrams and understand the principles of circuit operation, in relation to the performance of the individual components themselves.
Control of Linear Motion: Load, friction and inertia effects. Directional control, speed control, acceleration and deceleration, pressure controls and related circuits. Pressure losses and energy considerations, electronically operated valves. Pumps and Motors: Types and characteristics, volumetric and mechanical efficiencies, torque and power, effects of cavitation. Control of Rotary Motion: Motor systems, hydrostatic transmission.
