INDUSTRIAL HYDRAULICS HYDRAULICS • PNEUMATICS • INSTRUMENTATION • HYDROSTATICS •ELECTRONICS • PROGRAMMABLE CONTROLLERS

1. REVIEW
• Flow/pressure relationship; input horsepower, torque, force, Pascal’s Law
• Bernoulli’s Theorem of energy transfer through a fluid
2. FLUIDS & FILTRATION
• Petroleum based fluids • Filtration & contamination control
• High water content fluids - micron rating (absolute/nominal)
• Synthetic fluids - bypass - beta factor
• Seal & fluid compatibility - sizing - strainers
• Viscosity & specific gravity - suction, pressure, return line filters
3. RESERVOIRS (PRESSURIZED & NON-PRESSURIZED)
• Shape, size, features
4. STATIONARY POWER UNITS
• Valve & pump mounting considerations
• Heat dissipation/coatings & metals
5. PUMPS (POSITIVE DISPLACEMENT)
• Gear - external/internal • Pressure compensated/load sensing
• Vane - balanced & unbalanced • RPM, GPM, PSI ratings
• Piston - radial/axial • Cavitation causes
• Fixed displacement/variable displacement
6. VALVES
• Directional control; pilot operated • Pressure control
• Solenoid/manual control - relief valves-direct acting/pilot operated
• Flow control - pressure reducing valves
7. ACTUATORS
• Cylinders - single & double acting, piston speed flow & volume calculations
• Motors: torque, RPM, output horsepower, deceleration & acceleration,
breakaway friction
8 PLUMBING
• Hose, tubing, pipe
• 37 degree, 45 degree, flareless (bite, compression type) straight thread O-ring
• Reusable & permanent hose fittings, adaptors
9. ACCUMULATORS & INTENSIFIERS
10. LIMIT SWITCHES, PRESSURE SWITCHES, SENSORS & TRANSDUCERS
11. TROUBLE-SHOOTING METHODS
