Overview
Hydraulic systems power cranes, winches, valve actuators, wellhead control panels, drilling equipment, presses, lifting platforms and many types of mobile and fixed machinery in the oil, gas and industrial sectors. They deliver high forces in compact packages, but they are sensitive to contamination, overheating, leaks and incorrect adjustment. Most hydraulic failures are caused by dirty or degraded fluid, poor maintenance practices or a lack of understanding of how the circuit works. Hydraulic systems also store dangerous energy, and high pressure fluid injection injuries can be severe.
This course provides practical knowledge of hydraulic system maintenance and troubleshooting. Participants learn hydraulic principles, pressure, flow and power, and how to read hydraulic symbols and circuit diagrams. The course covers pumps, motors, cylinders, directional, pressure and flow control valves, accumulators, filters, reservoirs, hoses and fittings, and how each component works within the circuit. It also explains hydraulic fluids and contamination control, filtration and fluid analysis, preventive maintenance, setting and testing of pressures and flows, safe isolation and release of stored energy, hose inspection and replacement, and a systematic approach to troubleshooting slow operation, overheating, noise, leaks and pressure loss.
Objectives
- Explain hydraulic principles of pressure, flow, force and power
- Read hydraulic symbols and circuit diagrams with confidence
- Describe pumps, motors, cylinders, valves and accumulators in circuits
- Select hydraulic fluids and apply contamination control and filtration
- Carry out preventive maintenance and test pressures and flows correctly
- Isolate hydraulic systems safely and release stored energy before work
- Troubleshoot hydraulic faults using a systematic approach
Who should attend
Mechanical and hydraulic technicians, maintenance supervisors, crane and equipment mechanics, wellhead control technicians and reliability engineers.
Training methodology
The course combines explanation of hydraulic principles with circuit diagrams, component cutaways, fluid analysis reports and real troubleshooting cases. Participants read and trace circuits, identify components and their functions, calculate cylinder forces, speeds and pump flows, interpret particle counts and fluid analysis results, and prepare safe isolation procedures. Systematic fault-finding exercises use realistic symptoms from cranes, actuators and wellhead panels. Demonstrations on training rigs are included where available. Each day ends with a short quiz and discussion of hydraulic issues at participants' sites.
