The energy saving effect in HSHP-1000T hydraulic press was presented. Based on the disadvantage of high energy consumption of the conventional hydraulic press, the types of the accumulator and the application advantages were briefly described. And the pneumatic accumulator was used in the HSHP-1000T hydraulic system as an innovation. Through calculating the installed power and analyzing the accumulator influence to the hydraulic system, whether to install the accumulator or not was settled. The comparison shows that the introduction of accumulator could reduce the installed power for the hydraulic press, and improve the stability of the equipment.
