Hydraulic accumulator

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. [note 1] An accumulator enables a hydraulic system to cope with extremes of demand using a less powerful pump, to …

Hydraulic accumulator

Accumulator which stores a fluid under pressure and is therefore able to release hydraulic energy. Pressurisation is mainly based on gas pressure (air, nitrogen, "hydropneumatic accumulator") and, more rarely, springs or weights (spring accumulator, weighted accumulator).The latter is the only accumulator which keeps the pressure constant during withdrawal of the volume.

For the second model (Model II), a constant temperature in y-direction is presumed, whereas the temperature gradient in x-direction is still considered. In the simplest third model (Model III), a homogeneous temperature for the whole CFRP pipe is considered. The influence of these simplifications on the model accuracy is analyzed in Section 3.

Understanding the Function of Accumulators

Accumulators come in a variety of forms and have important functions in many hydraulic circuits. They are used to store or absorb hydraulic energy.
