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

用于控制执行元件的顺序动作时,液压泵启动后,先2YA通电,液压缸左腔进油,推动活塞方向右移。当碰到限位器(或死挡铁)后,系统压力升高,压力继电器发出电信号,使1YA通电,高压油进入液压缸的左腔,推动活塞右移。这时若3YA也通电,液压缸的活塞快速右移;若3YA断电,则液压缸的活塞慢速右移,其慢速运动速度由节流阀调节。

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。

压力继电器的主要性能有以下几个方面。
(1)调压范围
压力继电器能够发出电信号的低工作压力和高工作压力的范围称为调压范围。
(2)灵敏度与通断调节区间
系统压力升高到压力继电器的调定值时,压力继电器动作接通电信号的压力称为开启压力;系统压力降低,压力继电器复位切断电信号的压力称为闭合压力。开启压力与闭合压力的差值称为压力继电器的灵敏度。差值小则灵敏度高。为避免系统压力波动时压力继电器时通时断,要求开启压力与闭合压力有一定的差值,此差值若可调,则称为通断调节区间。
(3)升压或降压动作时间
压力继电器侧压力由卸荷压力升至调定压力时,微动开关触点接通发出电信号的时间称为升压动作时间,反之,压力下降,触点断开发出断电信号的时间称为降压动作时间。
(4)重复精度
在一定的调定压力下,多次升压(或降压)过程中,开启压力或闭合压力本身的差值称为重复精度,差值小则重复精度高。
选用标准
根据所测对象的压力来选用,比如所测压力范围在8KG以内,那么就要选用额定10KG的压力继电器,还有要符合电路中的额定电压,接口管径的大小。
