  • 2. HYDRAULIC SYSTEM  Characteristic  Components  Applications  Advantages & Disadvantages  Basic Circuit & Explanation
  • 3. CHARACTERISTIC  Wear Resistance  Oxidation Stability  Compressibility  Foam Resistance
  • 4. WEAR RESISTANCE  Wear resistance is a hydraulic fluid's ability to reduce the wear rate in frictional boundary contacts.  Anti wear hydraulic fluids contain anti wear components that can form a protective film on metal surfaces to prevent abrasion, scuffing, and contact fatigue.  Antiwear additives enhance lubricant performance and extend equipment life.
  • 5. OXIDATION STABILITY  Oxidation stability is a hydraulic oil's resistance to heat- induced degradation caused by a chemical reaction with oxygen.  Hydraulic oils must contain additives that counteract the process of oxidation, improve the stability and extend the life of the fluid.  Without these additives, the quality of the hydraulic oil will deteriorate quickly.
  • 6. COMPRESSIBILITY  Compressibility is a measure of the amount of volume reduction due to pressure.  Although hydraulic oils are basically incompressible, slight volume reductions can occur under certain pressure ranges.  Compressibility increases with pressure and temperature and has significant effects on high-pressure fluid systems.  It causes servo failure, efficiency loss, and cavitation; therefore, it is important for a hydraulic oil to have low compressibility.
  • 7. FOAM RESISTANCE  Foam results from air or other gases becoming entrained in the hydraulic fluid. Air enters a hydraulic system through the reservoir or through air leaks within the system.  A hydraulic fluid under high pressure can contain a large volume of dissolved or dispersed air bubbles. When this fluid is depressurized, the air bubbles expand and produce foam.  Proper foam inhibitors modify the surface tension on air bubbles so they more easily break up.
  • 8. COMPONENTS  Directional Control Valve  Motor  Pump  Filter  Cylinder  Tank
  • 9. DIRECTIONAL CONTROL VALVE  To control a direction of hydraulic fluids.
  • 10. MOTOR & PUMP  To energize the pump.  To distribute the fluid to system.
  • 11. FILTER  To separate moisture in fluids.
  • 12. CYLINDER  As a working medium.
  • 13. ACCUMULATOR  To store the power, absorb fluid fluctuation & stabilize system pressure.
  • 14. TANK  To store the cooling down the fluids.
  • 15. APPLICATIONS  Metal forming machinery  Conveyor systems  Foundries & primary metals plants  Presses, including cushions, clutches & brakes  Automated assembly systems  Packaging systems  Grinding & honing applications  Plastic injection & blow moulding  R & D test facilities  Plant central systems  Material handling & robotic systems
  • 16. ADVANTAGES & DISADVANTAGES  Advantages:  Flexibility  Multiplication of Force  Simplicity  Compact  Economy  Safety  Disadvantages:  Efficiency  Cleanliness
  • 17. BASIC CIRCUIT & EXPLANATION  The animations show the sequences in a basic hydraulic circuit in simplified form - the actuation and spring return of the final control element (4/2-way valve), the advance and return of the drive component (double acting cylinder) and the opening and closing of the pressure relief valve.
