4WEH10J44/6EG24N9ETK4/B10 力士乐电液伺服阀 电液阀是由一个主阀和两个电磁阀组成，主阀响应速度的控制是两个柱塞阀，安装于主阀的入口和出口。通过两个柱塞阀细微调节主阀的启闭速度。调整这些装置（柱塞阀）以控制流入和流出活塞上方介质的流量。达到主阀启闭速度能基于介质的粘度及压力调整的目的。
常开（N.O）和常闭（N.C）电磁阀分别安装在主阀的进油回路和出油回路中，用于控制主阀的动作，当两电磁阀通电时，进油孔（上游阀）回路关闭，先导孔（下游阀）回路打开，活塞上腔泄压，活塞上行，主阀打开。反之，活塞下行，主阀关闭。在主阀开启和关闭过程中，可将流量（流速）信号及阀塞位置信号传送给计算机，经过计算机处理后发出相应的指令，控制两个电磁导阀的通、断电状态，使活塞的上下腔的液压差产生变化，从而将活塞控制在所需的开启度上，实现对管道介质流量的控制。
电液比例阀简称比例阀。普通液压阀只能通过预调的方式对液流的压力、流量进行定值控制。但是当设备机构在工作过程中要求对液压系统的压力、流量参数进行调节或连续控制，例如.要求工作台在工作进给时按慢、快、慢连续变化的速度实现进给，或按一定精度模拟某个*控制曲线实现旅力控制.普通液压阀则实现不了。这时可以用电液比例阀对液压系统进行控制。
电液比例阀是一种按输入的电信号连续地、按比例地控制液压系统的液流方向、流量和压力的阀类。它山电-机械比例转换装置和液压控制阀本体两大部分构成.前者将输入的电信号连续地按比例地转换为机械力和位移输出，后者在接受这种机械力和位移之后、按比例连续地输出压力和流量.
电液比例阀的发展主要有两个途径一是用比例电磁铁取代传统液压阀的手动调节装置或取代普通电磁铁发展起来的;二是由电液伺服阀简化结构、降低精度发展起来的。下面介绍的比例阀均指前者，它是当今比例阀的主流。与普通液压阀可以互换。
比例电磁阀的结构如图5-27所示。比例电磁铁是直流电磁铁，但它与普通直流电磁铁不同。普通直流电磁铁的衔铁只有吸合和断开两个工作位置，并且在吸合时磁路中几乎没有气隙.而比例电磁铁要求吸合力或位移与给定电流成比例。并在衔铁的全部工作行程上，磁路中保持一定的气隙‘.其结构主要由极靴1、线圈2、壳体5和衔铁10等组成。线圈2中通电后产生磁场，因隔磁环4的存在。使磁力线主要部分通过衔铁10、气隙和极靴1，形成回路口极靴对衔铁产生吸力门在线圈中电流一定时。吸力的大小因极靴1与衔铁间的距离不同而变化。但衔铁在气隙适中的一段行程中，吸力随位置的改变发生的变化很小。
设计中就使比例电磁铁的衔铁在这段行程中工作。因此。改变线圈中的电流，即可在衔铁上得到与其成正比的吸力。用比例电磁铁代替螺旋手柄来调整液压阀，就能使输出乐力或流量与输人电流对应成比例地发生变化。
比例阀用于模拟控制，是介于普通开关控制与伺服控制之间的控制方式，它也特别适合于
设备的革新或改造。使设备自动化控制水平大为提高。其在现代液雌系统中占比例很大口
与普通液压阀相比.比例阀的优点是①能简单地实现远距离控制②能连续地、按比例地控制液压系统的压力和流量。从而实现对执行机构的位置、速度和力的连续控制，并能防止或减小压力、速度变换时的冲击;③油路简化，元件数量少。
比例阀适用于既要求能连续控制胀力、流量.和方向.而又不需要很I的控制精度的场合。
比例阀也分为压力阀、流量阀和方向阀几大类。近来又出现了功能复合化的趋势。

液压站又称液压泵站，是独立的液压装置，它按驱动装置（主机）要求供油，并控制油流的方 向、压力和流量，它适用于主机与液压装置可分离的各种液压机械下。 用户购买后只要将液压站与 主机上的执行机构（油缸和油马达）用油管相连，液压机械即可实现各种规定的动作、工作循环。
液压站[The hydraulic pressure stands ]液压站是由液压泵、驱动用电动机、油箱、溢流阀等构成的液压源装置或包括控制阀在内的液压装置。按驱动装置要求的流向、压力和流量供油，适用于驱动装置与液压站分离的各种机械上，将液压站与驱动装置（油缸或马达）用油管相连，液压系统既可实现各种规定的动作。工作原理电机带动油泵工作提供压力源，通过集成块、液压阀等对驱动装置（油缸或马达）进行方向、压力、流量的调节和控制，实现各种规定动作。

液压站组成及工作原理
液压站又称液压泵站，是独立的液压装置，它按驱动装置（主机）要求供油，并控制油流的方 向、压力和流量，它适用于主机与液压装置可分离的各种液压机械下。
用户购买后只要将液压站与 主机上的执行机构（油缸和油马达）用油管相连，液压机械即可实现各种规定的动作、工作循环。 液压站是由泵装置、集成块或阀组合、油箱、电气盒组合而成。
各部件功用如下
泵装置——上装有电机和油泵，它是液压站的动力源，将机械能转化为液压油的动力能。
集成块——是由液压阀及通道体组合而成。它对液压油实行方向、压力、流量调节。
阀组合——是板式阀装在立板上，板后管连接，与集成块功能相同。
油 箱——是钢板焊的半封闭容器，上还装有滤油网、空气滤清器等，它用来储油、油的冷却 及过滤。
电器盒 ——分两种形式。
一种设置外接引线的端子板；一种是配置了全套控制电器。
液压站的工作原理如下
电机带动油泵旋转，泵从油泵中吸油后打油，将机械能转化为液压油 的压力能，液压油通过集成块（或阀组合）被液压阀实现了方向、压力、流量调节后经外接管路传 输到液压机械的油缸或油马达中，从而控制了液动机方向的变换、力量的大小及速度的快慢，推动 各种液压机械做功。
液压站结构形式及主要技术参数
液压站的结构形式，主要以泵装置的结构形式、安装位置及冷却方式来区分，按泵装置的机构
形式安装位置可分三种
1、上置立式泵装置立式安装在油箱盖板上，主要用于定量泵系统一思想
2、上置卧式泵装置卧式安装在油箱盖板上，主要用于变量泵系统，以便于流量调节。
3、旁置式泵装置卧式安装在油箱旁单独的基础上，旁置式可装备备用泵，主要用于油箱容量 大250升，电机功率7.5千瓦以上的系统。
按站的冷却方式可分为两种
1、自然冷却靠油箱本身与空气热交换冷却，一般用于油箱容量小于250升的系统一思想。4WEH22H76/6SG24N9EK4/B10
2、强迫冷却采取冷却器进行强制冷却，一般用于油箱容量大于250升的系统。 液压站以油箱的有效贮油量度及电机功率为主要技术参数。 油箱容量共有18种规格（单位升/L） 25、40、63、100、160、250、400、630、800、1000、1250、1600、2000、2500、3200 、4000、5000、6000 本系列液压站根据用户要求及依据工况使用条件，可以做到 1、按系统配置集成块，也可不带集成块。 2、可设置冷却器、加热器、蓄能器 3、可设置电气控制装，也可不带电气控制装置
