However, traditional exhausted air storage tanks have the disadvantages of unstable pressure and low energy density. To solve these problems, this paper presents an energy-saving method by exhausted air reuse for industrial pneumatic actuation systems based on a constant pressure elastic accumulator.
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.
Wang et al. designed an isobaric compressed air storage tank based on a special shaped cam conversion unit. The pressure fluctuation rate of the air storage device was about 2%, which reduced the energy consumption by about 18.7% compared with the traditional constant volume air storage device.
When the air tank reached a certain pressure, it drove an indirect energy conversion device to generate power and store energy, which saved energy by 31% [ 7 ]. Elija et al. put forward a control framework for exhausted air reuse, which saved energy up to 38% under different working conditions [ 8 ].
Author to whom correspondence should be addressed. Exhausted air reuse is one of the most important energy-saving methods for pneumatic actuation systems. However, traditional exhausted air storage tanks have the disadvantages of unstable pressure and low energy density.
The variation range of energy-saving efficiency is 21.1–54.1%, respectively. Results show that applying a pneumatic strain energy accumulator to an exhaust recovery system for compressed air energy saving has a good energy-saving effect. Residual air in the accumulator has a negative impact on energy-saving efficiency.
