Hydraulic Systems: Principles, Operation and Maintenance

Introduction

This Hydraulic Systems training course provides participants with a practical understanding of hydraulic power systems, their principal components, operating characteristics and maintenance requirements. Hydraulic systems are extensively used across industrial plants and machinery because of their ability to transmit high forces and provide precise control. Achieving reliable performance requires personnel to understand how hydraulic components interact, how fluid condition influences equipment performance and how operating problems can be identified before they develop into significant failures.

Participants will examine the major components found within industrial hydraulic systems, including fixed and variable displacement pumps, hydraulic cylinders and motors, pressure and directional control valves, filters, reservoirs and accumulators. The course develops the ability to interpret standard hydraulic symbols and circuit diagrams while explaining the operation of commonly used industrial hydraulic circuits. Particular attention is given to hydraulic fluid properties, contamination-related problems, component inspection and safe system operation. The training course progresses from fundamental hydraulic principles through component operation and circuit analysis to maintenance and troubleshooting. 

This Hydraulic Systems training course will highlight:

• Applying fundamental principles of hydraulic power and fluid behaviour
• Understanding hydraulic fluids, contamination and filtration requirements
• Evaluating fixed and variable displacement hydraulic pumps and actuators
• Understanding pressure, directional and flow control valve operation
• Interpreting hydraulic symbols and analysing industrial hydraulic circuits
• Applying effective inspection, maintenance and troubleshooting practices
