液压系统结构

液压系统由信号控制和液压动力两部分组成，信号控制部分用于驱动液压动力部分中的控制阀动作。

液压动力部分采用回路图方式表示，以表明不同功能元件之间的相互关系。液压源含有液压泵、电动机和液压辅助元件；液压控制部分含有各种控制阀，其用于控制工作油液的流量、压力和方向；执行部分含有液压缸或液压马达，其可按实际要求来选择。

比例溢流阀的压力控制阀

比例溢流阀的特点是调定的压力与输入电流大小成正比，即输入的电流大，调定的压力高。

当通过计算机键盘输入被折板料的抗拉强度，厚度，长度以及下模V型槽开口宽度后，计算机按折弯力计算公式求得所需折弯力，经数模转换后，通过控制比例溢流阀的电控器，向比例溢流阀输入适当的电流值，从而达到控制折弯力大小的目的。板料折弯机所需小折弯力和允许的大折弯力要与比例溢流阀的压力特征曲线相对应，并且使调定的压力稍大于所需折弯力，以利于板料的顺利折弯。

比例溢流阀的压力控制一般为开环，如接入压力传感器，可进行闭环控制。

带电气位置反馈和集成电子元件 (OBE) 的先导式高频响方向阀

4WRTE

规格 10 … 35

组件系列 4X

较大工作压力 350 bar

较大流量 3000 l/min

额定流量 25 … 1000 l/min

产品说明

4WRTE 型阀门是一个带电气位置反馈、集成电子元件 (OBE) 和可选阀芯位置监控的先导式方向控制阀。

设置

阀门基本构成包括 3 个主要组件：

带有主级控制阀芯 (2) 和可选阀芯位置监控 (13) 的壳体 (1)

带主级感应式位置传感器 (3) 的集成电子元件（可选配电子元件保护膜（14））

带有控制阀芯/插口设备 (5)、感应式位置传感器 (6) 和主级控制阀芯 (2) 的中心位置压力反馈的先导控制阀 (4)

功能

比例电磁铁（7 和 8）断电后，主级控制阀芯 (2) 将通过对中弹簧 (9) 和压力反馈保持在中心位置

主级控制阀芯 (2) 通过先导控制阀 (4) 进行控制 → 主级控制阀芯 (2) 位于调节位置

通过更改比例电磁铁（7、8）的线圈磁力以控制先导控制阀 (4) 的控制阀芯

集成电子元件的控制值与理论值的连接

先导油可通过油口 P 从内部供给先导控制阀，也可通过油口 X 从外部供给先导控制阀。先导油回油从内部通过油口 T 或从外部通过 Y 泄至油箱

在控制值为 0 V 的情况下，电子元件将主级控制阀芯 (2) 控制在中心位置。

阀芯位置监控

主级控制阀芯 (2) 的阀芯位置通过位置感应开关 (13) 进行检测，然后通过两个具有预设逻辑的转换输出进行显示。如果超过固定设置转换点，则控制阀芯遮盖中将监控与零位置的偏差（请参阅“附件”）。

可在用于监视功能的高等控制中使用这些切换信号。通过带两个信号输出插脚和两个电源插脚的 4 极连接器 M12x1 单独进行电气连接。

应用领域

阀门可以用于与安全相关的双通道应用（符合 EN 13849-1 标准的类别 3，PL d 和 类别 4，PL e），例如一个通道的关闭元件。阀门符合 EN 60204 标准中停机类别 0 的安全启动关闭要求。

如果需要安全要求，阀门的电源电压必须基于

所需的安全等级（类别 PL）进行安全断电。

根据应用和工作设备要求 - 符合 EN 13849-1 的特定标准，用户必须提供符合所需

诊断范围 DCavg 并使用高等控制的适当监控/可信性检查。

安全阀是启闭件受外力作用下处于常闭状态，当设备或管道内的介质压力升高超过规定值时，通过向系统外排放介质来防止管道或设备内介质压力超过规定数值的特殊阀门。安全阀属于自动阀类，主要用于锅炉、压力容器和管道上，控制压力不超过规定值，对人身安全和设备运行起重要保护作用。注安全阀必须经过压力试验才能使用。
