0811404612 4WRPEH6C4B24L-2X/G24K0/A1M德国博世力士乐REXROTH比例阀

组成:

比例电磁铁 直动式溢流阀主体

工作原理:

输入一I，产生一电磁力，作用于阀心上，得到- -控制压力，其pI, I变化，p也变化。

电液比例换向阀

比例电磁铁替代普通电磁换向阀中的普通电磁铁即可。

工作原理:输入- ~I,得到一个运动方向，并且还可改变输出流量的

大小;改变电流信号较性，即可改变运动方向。

比例调速阀

组成:

比例电磁铁替代调速阀中的调节螺帽即可。

工作原理:输入—I, 得到一相应运动，使节流阀阀口变化，流量变化

比例阀对流量的控制可以分为两种：

一种是开关控制：要么全开、要么全关，流量要么大、要么小，没有中间状态，如普通的电磁直通阀、电磁换向阀、电液换向阀。

另一种是连续控制：阀口可以根据需要打开任意一个开度，由此控制通过流量的大小，这类阀有手动控制的，如节流阀，也有电控的，如比例阀、伺服阀。
比例伺服阀的主阀一般来说和换向阀一样是滑阀结构，只不过阀芯的换向不是靠电磁铁来推动，而是靠前置级阀输出的液压力来推动，这一点和电液换向阀比较相似，只不过电液换向阀的前置级阀是电磁换向阀，而伺服阀的前置级阀是动态特性比较好的喷嘴挡板阀或射流管阀。

三位四通方向阀

4WRPE 型阀门是带有电气位置反馈和集成电子元件 (OBE) 的直动式方向控制阀。

结构

阀门的基本构成包括：

阀体 (1)

带有压缩弹簧（3.1 和 3.2）的控制阀芯 (2)

带位置传感器 (4) 的控制线圈（可选配电子元件保护膜 (8)）

行程线圈 (7)

带模拟接口 (6) 或 IO-Link 接口的集成电子元件 (OBE) (5)（可选配衰减阀板 (9)）

功能

集成电子元件 (OBE) 将****控制值与实际位置值进行比较。在有控制偏差的情况下，将激活相关线圈。由于磁力发生改变，控制阀芯 (2) 将扺住相应弹簧进行调节。行程/控制阀芯剖面以与控制值成比例的方式进行控制。在控制值预设值为 0 V 的情况下，电子元件将控制阀芯 (2) 调节到中心位置。

错误检测

如果出现以下错误情况，电子元件将使控制线圈断电：

低于较小电源电压 ≤ 15 V（重新启动 ≥ 17.5 V）。

仅在接口 "F1" 处：

低于较小电流控制值 2 mA（包括控制值线的电缆中断（电流环））。

仅在接口 "L1" 处：

使能未激活，通讯中断（看门狗）

内部 IO-Link 发生故障时

仅在接口 "C6" 处：

额外使能未激活

控制阀芯 (2) 在压缩弹簧（3.1 和 3.2）的作用下保持在机械中心位置（（带有符号 V）不适用于液压中心位置）。

衰减阀板 "D"

衰减阀板 (9) 降低加速振幅集成电子元件上的加速振幅（频率 >300 Hz）。

注意：

对于主要为低激励频率 (<300 Hz) 的应用，不建议使用衰减阀板。

电子元件保护膜“-967”

要保护集成电子元件 (OBE) 壳体中的冷凝格式，可以使用电子元件保护膜 (8)。

建议用于空气湿度高且周期温度变化明显的外部工业标准条件（例如室外）。
