美国尼伯科NE-SR5系列弹簧复位电动执行机构(1) Series NE-SR5 Electric Spring Reture Actuator(1) |
美国尼伯科有限公司 |
THE ELECTRIC SOLUTION NE-SR5系列特别适用于自动开启/关闭需要解决动力损失的系统环境。 当动力正常时,这个系列的执行机构的运转和普通执行机构一样。 · 当动力正常,弹簧伴随着执行机构的移动而移动。 · 当动力供应中断,通过机电制动器的作用,执行机构和弹簧固定在断电所处的位置上。 · 当动力损失时,弹簧会释放弹力,驱动执行机构恢复到预置的故障保护安全位置。 NIBCO has taken the lead in offering a cost effective Electric Spring Return Actuator. The NE-SR5 Series actuator offers a variety of solutions when a system needs protection against a loss of power. The NE-SR5 is designed for use in environments where automatic closing/opening is required upon loss of power. When power is available the device operates like a normal quarterturn actuator. · Under powered operation, the spring pack travels with the movement of the actuator. · Under powered stopped conditions, the actuator and spring are held in position via the electric mechanical brake · Under loss of power, the spring is released and drives the actuator to the pre-designated failsafe position.
