产品说明

HED 8 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 (1)、带柱塞的安装套件 (2)、压缩弹簧 (3)、调节元件 (4) 和微动开关 (5)。

如果要监测的压力低于调定压力，则操作微动开关 (5)。要监测的压力通过节流孔 (7) 传到柱塞 (2)。柱塞 (2) 受弹簧座 (6) 支持并克服压缩弹簧 (3) 不断变化的作用力。弹簧座 (6) 将柱塞 (2) 的运动传输到微动开关 (5)，并在达到调定压力时释放后者的压力。这会打开或关闭电路，具体取决于电路设置。弹簧座 (6) 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 (5) 免于受到机械损伤，并防止压缩弹簧 (3) 的固态压缩。

注意：

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。
