  3. Hydraulic Components • Accumulator Functions • Energy Storage • Stabilize Pump Pulsation • Stabilize Load Shocks • StoreVolumeUnderPressure For High Volume Demands

  4. Hydraulic Components • Accumulators • What You Don't Know About Hydraulic Accumulators Can KILL You! Click Below For Video • https://www.youtube.com/watch?v=-oXh3FILZdg • Gas Accumulator Pressure Test • https://www.youtube.com/watch?v=6e8ZVCKCO1U

  5. Hydraulic Components • Accumulator Types • Spring Loaded • Gas Charged (Nitrogen) • Weight Loaded • Hydraulic Counter Loaded

  6. Accumulator Types • Spring Loaded Types • Sealed Piston Piston may be sealed with an O-ring, quad ring, or square ring and may even be backed up with a Teflon cushion washer depending on pressure requirements of system and spring strength

  7. Accumulator Types • Spring Loaded Types • Sealed Piston • Compound Spring This accumulator system is often used for variable loads or independent pressure volumes for light load extensions in sequential operation

  8. Accumulator Types • Spring Loaded Types • Sealed Piston • Compound Spring • Diaphragm • The sprung side may be pneumatically boosted

  9. Accumulator Types • Spring Loaded Types • Sealed Piston • Compound Spring • Diaphragm • Hydraulic Counter Loaded Notice: 2 different size pistons allowing for mechanical advantage boosting that are balanced by 2 springs working against each other (learn the math!!)

  10. Accumulator Types • Spring Loaded Types • Sealed Piston • Compound Spring • Diaphragm • Hydraulic Counter Loaded • Spring with Bellows

  11. Review Spring Types • Spring Loaded Types • Sealed Piston • Compound Spring • Diaphragm • Hydraulic Counter Loaded • Spring with Bellows

  12. Hydraulic Components • Accumulator Types • Spring Loaded • Gas Charged (Nitrogen) • Weight Loaded • Hydraulic Counter Loaded

  13. Accumulator Types • Gas Charged Types • Bladder Type • Diaphragm Type • Sealed Piston Type • Metal Bellows Type • Usually Nitrogen (Nuetral)

  14. Accumulator Types • Gas Charged Types
