Energy accumulator and cylinder stroke

What is the stroke of a hydraulic accumulator?

The stroke of each cylinder is 600 mm. In general, a hydraulic accumulator utilizes the compressibility of gas to store energy. According to the ideal-gas law (assuming nitrogen as an ideal gas) the relationship between gas or oil volume and pressure of the accumulator can be generalized as a polytropic [ 33 ].

What is a pneumatic strain energy accumulator?

The pneumatic Strain Energy Accumulator is a recently developed device that recycles exhaust gas from one pneumatic component, stores it in a highly efficient process, and reuses the stored exhaust gas at a constant pressure to power another pneumatic component.

How does a constant pressure energy storage accumulator work?

Employing the hyperelastic mechanical properties of rubber, a constant pressure energy storage accumulator is designed and applied to a pneumatic circuit for exhausted air recovery and energy saving. In the circuit, the accumulator recovers exhausted air from a primary cylinder and supplies it to another secondary cylinder.

Does a pneumatic strain accumulator affect cylinder running speed?

Although the additional pneumatic accumulator will improve the energy efficiency of a pneumatic system, when the pneumatic strain energy accumulator is connected to the exhaust end of the cylinder for compressed air recovery, it will inevitably produce back pressure, which will affect the cylinder running speed and motion stability.

How are energy storage accumulators arranged?

One chamber is arranged to the energy storage accumulator for energy saving. Other chambers are flexibly connected to the pump ports for variable transmission ratios. Areas of multiple chambers are designed to permit a symmetric single-rod cylinder. Three modes are switched by solenoid valves to expand force-velocity capabilities.
