1.压力继电器,液压术语,是液压系统中当流体压力达到预定值时,使电接点动作的元件。
2.是将压力转换成电信号的液压元器件,客户根据自身的压力设计需要,通过调节压力继电器,实现在某一设定的压力时,输出一个电信号的功能。
工作原理
压力继电器是利用液体的压力来启闭电气触点的液压电气转换元件。当系统压力达到压力继电器的调定值时,发出电信号,使电气元件(如电磁铁、电机、时间继电器、电磁离合器等)动作,使油路卸压、换向,执行元件实现顺序动作,或关闭电动机使系统停止工作,起安全保护作用等。
压力继电器有柱塞式、膜片式、弹簧管式和波纹管式四种结构形式。下面对柱塞式压力继电器(见图)的工作原理作一介绍:
当从继电器下端进油口3进入的液体压力达到调定压力值时,推动柱塞2上移,此位移通过杠杆放大后推动微动开关4动作。改变弹簧1的压缩量,可以调节继电器的动作压力。
应用场合:用于安全保护、控制执行元件的顺序动作、用于泵的启闭、用于泵的卸荷。
注意: 压力继电器必须放在压力有明显变化的地方才能输出电信号。若将压力继电器放在回油路上,由于回油路直接接回油箱,压力也没有变化,所以压力继电器也不会工作。
