力士乐压力开关HED8OA-2X/350K14AS

压力开关的工作原理及特点  

压力开关是一种简单的压力控制装置，当被测压力达到额定值时，压力开关可发出警报或控制信号。压力开关的一般工作原理：是当系统内压力高于或低于额定的安全压力时，感应器内膜片片瞬时发生移动，通过连接导杆推动开关接头接通或断开，当压力降至或升额定的恢复值时，膜片瞬复位，开关自动复位，或者简单的说是当被测压力超过额定值时，弹性元件的自由端产生位移，直接或经过比较后推动开关元件，改变开关元件的通断状态，达到控制被测压力的目的。压力开关采用的弹性元件有单圈弹簧管、膜片、膜盒及波纹管等。开关元件有磁性开关、水晶开关、微动开关等。 

压力开关主要类别包括常开式和常闭式。主要特点是：

1、采用英制管螺纹快速接头或铜管焊接式安装结构，安装灵活，使用方便，无需特殊的安装固定。

2、插片式导线式连接方可供用户任意选定。

4、密封式不锈钢感应器安全可靠。

5、压力范围内可根据用户任意选定的压力值进行制造。 

压力开关主要应用领域：主要用于家用、商用、汽车制冷系统的高、低压力保护控制，蒸汽工况和发电站;蓄能器,接收器,闪蒸罐,分离器,洗涤器,炼油装置。也可适用于各种设备工具的高、低压力保护控制。

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。
