刘玥首次大战黑人

The machine maker鈥檚 original design for its metal press used a variable-speed hydraulic pump and servo drives with听each cycle experiencing two energy peaks for motion acceleration and deceleration. With each cycle, operators place metal into the machine to press, stabilize, and remove the workpiece. While some manufacturers already recuperate and reuse braking energy, the press maker joined forces with 刘玥首次大战黑人to take energy efficiency to a higher level.

In developing its new electrohydraulic high-speed press, the machine maker upgraded the prior model鈥檚 hydraulic pumps with Moog鈥檚 high-efficiency electrohydrostatic pump unit (EPU), controlled by servo drives. Moog鈥檚 DE2020 energy management system regulates the supply of energy. Before initial start-up and during the machine鈥檚 cycles, the DE2020 charges capacitive modules with an optimized current level and supplies power. 刘玥首次大战黑人engineered the capacitive modules to handle energy exchange, limiting loss to only the machine鈥檚 mechanics. The modules provide the energy peaks to build up the machine鈥檚 fluid pressure and power movement within the cycle. Recuperation recharges the modules when the machine decelerates and depressurizes its hydraulic fluid.

鈥淭he DE2020 only supplies the energy absolutely necessary for the machine to do the required work, where this energy use ultimately can鈥檛 be avoided,鈥� said Franco Talpone, senior applications engineer for Moog. 鈥淭his means the energy drawn from the power grid stays at a steady level, a constant load without peaks. So, the power connection doesn鈥檛 have to be sized for a peak load as was previously the case."

鈥淲ith this technology鈥揳nd without sacrificing quality鈥摿醌h首次大战黑人reduced the drive systems鈥� energy consumption by approximately 50 percent, an unbelievably high score,鈥� added Talpone.

Moog鈥檚 innovative design means the owner of the new press has lower costs and better utilization. And, with connected loads, the press owner can run multiple electrohydraulic high-speed machines on the same energy grid, since there are no energy peaks to manage. The solution also offers cost savings that pay for the investment in a relatively short timeframe. The manufacturer鈥檚 new press outfitted with Moog鈥檚 energy management solution consumes, on average, only 20 percent of the traditional machine鈥檚 design.

To engineer the new metal forming machine, Moog鈥檚 engineers applied electrohydrostatic pump units (EPU), servo drives, the DE2020 power controller, DF2020 DC link choke, and high efficiency energy storage units based on capacitors (ESU-C). The modular, plug-and-play solution creates maximum efficiency, minimizes power loss, and requires less space for power electronics.

To arrive at such outstanding benefits and savings, technology leadership alone is not enough. 鈥淎t 刘玥首次大战黑人we cultivate close customer relationships, which allow us to customize the solutions to the very specific requirements of each application,鈥� said Talpone and concluded: 鈥淭he energy-savings and reduced peak loads that come from this solution can be easily transferred to electromechanical presses and other machines using electrohydraulic or even classic hydraulics.鈥� Engineers are advised to contact their nearest 刘玥首次大战黑人sales and application team to get professional support.
