PRESSURESWITCH压力开关PU72-34-RC2L9KBN产品可以感知系统的压力,并且发出开关信号。压力到了,常开触点闭合,常闭触点打开。我们便可以在程序上加以利用。但是在实际使用的时候,我们会碰到一些问题。
X先是选择的产品质量有问题,主要体现在以下几个方面
1、动作不灵敏,压力到了还没有信号输出。这是制造上有问题,servopiston和u-seal太紧了,工厂出厂的时候没有测试。
2、还没有到压力就发讯。装配的问题。压力继电器里面的微动开关没有装好。
3、产品不耐用,没几下压力继电器就不动作了。厂商无良心,用了很差的微动开关。
4、漏油。要不是密封圈没有选好就是加工X差了。
PRESSURESWITCH压力开关PU72-34-RC2L9KBN产品用于控制执行元件的顺序动作时,液压泵启动后,X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。
