HED8OA-2X/350K14力士乐压力开关 压力继电器

HED8类型的液压-电气压力开关是柱塞式压力开关。它们的基本构成是壳体、带柱塞的安装套件、压缩弹簧、调节元件和微动开关。

如果要监测的压力低于调定值，则操作微动开关。要监测的压力通过节流孔传到柱塞。柱塞受弹簧座支持并克服压缩弹簧不断变化的作用力。弹簧座将柱塞的运动传输到微动开关，并在达到调定压力时释放后者的压力。这将打开或关闭电路，取决于电路的设置。弹簧座的机械前挡块在压力突然降低和过压的情况下，可保护微动开关免于受到机械损伤，并防止压缩弹簧的过压。

要延长使用寿命，安装压力开关时应确保振动较小，使其免于受到液压冲击。

请务必遵守密封件与所用液压油的兼容性！

1) 阀板用于垂直叠加，单独订购，请参阅附件

2) 不允许用于垂直叠加，不带低温密封件，未经过 UL 认证

3) 连接插头，单独订购，

4) H 钥匙，物料号 R900008158，包括在交付范围内

5) 只能使用压力计（刻度用于指示作用）较好设置切换压力

压力继电器有直动型和先导型;也有带延时调节和不带延时调节的; 也有弹簧调节型和开关位置调节型。各种压力继电器尽管类型不同,原理只有一个,即靠液体压力与弹簧力的平衡,使柱塞或杠杆产生一定的位移,将电气开关接通与断开。压力继电器的任务是把系统某 较稳定的压力信号反映出去, 以控制其它的顺序动作,但它由于自身和外界的原因,有可能发出误信号,影响液压系统的工作可靠性和安全性。

力士乐REXROTH监测模块

液压系统采用限压式变量泵和调速阀组成容积节流调速系统,把调速阀装在进油路上,而在回油路上加背压阀。这样就获得了较好的低速稳定性、较大的调速范围和较高的效率。而且当滑台需死挡铁停留时,用压力继电器发出信号实现快退比较方便。
