Hydraulic accumulator

OverviewTypes of accumulatorFunctioning of an accumulatorSee alsoExternal links

A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy. The external source can be an engine, a spring, a raised weight, or a compressed gas. An accumulator enables a hydraulic system to cope with extremes of demand using a less powerful pump, to respond more quickly to a temporary demand, and to smooth out pulsations. It is a type of energy storage

Hydraulic and Energy Grades

Sizing Hydraulic Breakers/Hammers

SMALL HYDRAULIC BREAKERS (HAMMERS): up to 1200-ft.lbs. (1627 Joules), are typically used in concrete and other light duty work. MEDIUM HYDRAULIC BREAKERS (HAMMERS): 1200 – 4000-ft.lbs. (1627 – 5423 Joules) are used in both concrete and rock applications with limitations on the size and amount of material to be broken.

What is Water Hammer or Hydraulic Shock? Burt Process

Hydraulic shock, or water hammer, occurs when a valve is quickly closed while the liquid is coming full force through the pipe. If a surge suppressor is properly charged, sized correctly, and placed upstream of the valve, the fluid flow is directed up into the surge suppressor which acts as a spring and absorbs the wave.
