电梯试验专用摆锤,门摆锤,轿壁冲击摆锤 软摆锤 硬摆锤 摆锤冲击试验机配件
一、【电梯试验专用摆锤】执行标准:
二、【电梯试验专用摆锤】国家标准:
2
硬摆锤:Φ3.5mm(±0.25),总质量为(10±0.5)Kg;
2
软摆锤:Φ3.5mm(±1),总质量为(45±0.5)Kg;
三、【电梯试验专用摆锤】防止二次冲击:
光电感应开关感应到冲击锤摆动到被冲击样品的一瞬间,提供信号给PLC,然后PLC按设定的时间延时一定时间后控制伺服电机驱动提升一定的高度,拉紧连接冲击锤上的软绳,当摆锤冲击样品弹开后拉住摆锤,防止二次冲击
Photoelectric
induction switch induction to hammer swing to a moment is the impact of
the sample and provides a signal to the PLC, then the PLC according to
the set time delay some time after control servo motor drive to upgrade a
certain height, tightly connected impact hammer soft rope, when the
pendulum hammer impact sample bomb after pull pendulum to prevent second
impact.
