Outline: |
|
Safety - safe working habits, identifying safety hazards, safety in circuit design, safely troubleshooting a hydraulic circuit
Fluid Power Principles and Laws - review the basic principles of force, flow, pressure, work and power, Pascal's Law and pressure/force/flow relationships
Hydraulic Circuit Components - pumps (positive displacement pumps, principles of operation, pressure compensation, load-sensing), motors (principles of operation, selection for circuit requirements), cylinders (types, seals, sizing), directional controls (2-, 3- and 4-way valves, valve terminology, manual, solenoid and pilot operation, proportional valves), flow control valves (non-compensated, pressure-compensated, temperature-compensated, principles of operation), pressure control valves (relief valves, sequence, counterbalance, unloading, pressure reducing valves, principles of operation), check valves (pilot-operated, shuttle, rectifier), lines and fittings (pipe/tube/hose, sizing, installation), fluids (types and characteristics), accumulators, actuators
Contamination and Filtration - selecting filters and preventing contamination
Advanced Troubleshooting - identifying installation problems, identifying circuit failures, failure symptoms, diagnostic equipment, pressure/flow issues, common cylinder problems, common pump problems, leakage control, maximizing efficiency in the hydraulic circuit, techniques to prevent component and circuit failure
Adjustment and Calibration - adjustment and calibration of all components in the hydraulic circuit |
