电液比例阀是比例控制系统中的主要功率放大元件,按输入电信号指令连续地成比例地控制液压系统的压办流量等参数。与伺服控制系统中的伺服阀相比,在某些方面还有一定的性能差距(主要性能比较如表1所示),但它显著的优点是抗污染能力强,大大地减少了由污染而造成的工作故障,提高了液压系统的工作稳定性和可靠性。另一方面比例阀的成本比伺服阀低，结构也简单,已在许多场合获得广泛应用。

比例阀按功能分为三大类
(1)比例压力阀。有溢流阀减压阀,分别有直动和先导两种结构;可连续地或按比例地远程控制其输出油液压力;
(2)比例换向阀。有直动和先导两种结构,直动阀有带位移传感器和不带位移传感器两类。由于使用了比例电磁铁阀芯不仅可以换位，而且换位的行程可以连续地或按比例地变化。因而连通油口间的通流面积也可以连续或按比例地变化。所以比例换向阀不仅能够控制执行元件的方向而且能够控制其速度。因为这个原因比例阀中的比例换向阀应用也普遍;
(3)比例流量阀。有比例调速阀和比例溢流流量控制阀,可连续地或按比例地远程控制其输出流量。
比例阀的输入单元是电-机械转换器,它将输入的电信号转换成机械量转换器有伺服电机和步进电机力马达和力矩马达比例电磁铁等形式。但常用的比例阀大都采用了比例电磁铁，比例电磁铁根据电磁原理设计,能使其产生的机械量(力或力矩和位移)与输入电信号(电流)的大小成比例,再连续地控制液压阀阀芯的位置，进而实现连续地控制液压系统的压力方向和流量。比例电磁铁的结构，它由线圈、衔铁推杆等组成,当有信号输入线圈时,线圈内磁场对衔铁产生作用力,衔铁在磁场中按信号电流的大小和方向成比例连续地运动,再通过固连在一起的销钉带动推杆运动,从而控制滑阀阀芯的运动。应用的比例电磁铁是耐高压直流比例电磁铁。

比例电磁铁的类型按照工作原理主要分为
如下几类:
(1)力控制型
这类电磁铁的行程短，只有1 5mm,输出力与输入电流成正比,常用在比例阀的先导控制级
上:
(2)行程控制型
由力控制型加负载弹簧共同组成，电磁铁输出的力通过弹簧转换成输出位移,输出位移与输入电流成正比，工作行程达3mm,线性好，可以用在直控式比例阀上;
(3)位置调节型
衔铁的位置由传感器检测后,发出一个阀内反馈信号,在阀内进行比较后重新调节衔铁的位置。阀内形成闭环控制,精度高,衔铁的位置与力
无关，精度高的比例阀如德国的博世意大利的阿托斯等都采用这种结构。
比例阀与放大器配套使用放大器采用电流负反馈,设置斜坡信号发生器阶跃函数发生器、PD调节器反向器等,控制升压降压时间或运动加速度及减速度。断电时, 能使阀芯处于安全位置。
比例电磁铁和液压阀组成电液比例阀。由于比例电磁铁可以在不同的电流下得到不同的力(或行程),因此可以无级改变压力、流量。故比例电磁铁是比例阀的关键元件。

(1)比例环节
比例环节也称为无惯性环节,对液压缸或马达，忽略液压油的可压缩性和泄漏,液压缸的流量Q= VA。其中V为活塞速度;A为活塞面积。其传递函数为: g(s)= V (s)/Q(s)= 1/A =式中K为比例环节放大系数或增益,表示输入量经过放大K倍后输出。
(2)比例控制系统
比例控制系统根据有无反馈分为开环控制和闭环控制。如比例阀控制液压缸或马达系统可以实现速度位移转速和转矩等的控制。
由于开环控制系统的精度比较低,无级调节系统输入量就可以无级调节系统输出量力速度以及加减速度等。这种控制系统的结构组成简单,系统的输出端和输入端不存在反馈回路,系统输出量对系统输入控制作用没有影响,没有自动纠正偏差的能力,其控制精度主要取决于关键元器件的特性和系统调整精度，所以只能应用在精度要求不高并且不存在内外干扰的场合。开环控制系统一.般不存在所谓稳定性问题。
闭环控制系统(即反馈控制系统)的优点是对内部和外部干扰不敏感，系统工作原理是反馈控制原理或按偏差调整原理。这种控制系统有通
过负反馈控制自动纠正偏差的能力。但反馈带来了系统的稳定性问题，只要系统稳定，闭环控制系统可以保持较高的精度。因此, 目前普遍采用闭环控制系统。

液压执行元件
将液压能转换为机械能的装置，其作用是在压力油的推动下输出力和速度或转矩和速度，以驱动工作装置做工。例如液压缸、液压马达。
2.1液压马达
液压马达习惯上是指输出旋转运动的，将液压泵提供的液压能转变为机械能的能量转换装置。
液压马达亦称为油马达，主要应用于注塑机械、船舶、起扬机、工程机械、建筑机械、煤矿机械、矿山机械、冶金机械、船舶机械、石油化工、港口机械等。
高速马达齿轮马达具有体积小、重量轻、结构简单、工艺性好、对油液的污染不敏感、耐冲击和惯性小等优点。缺点有扭矩脉动较大、效率较低、起动扭矩较小(仅为额定扭矩的60%-一70%)和低速稳定性差等。
2.2液压缸
液压缸是将液压能转变为机械能的、做直线往复运动(或摆动运动)的液压执行元件。它结构简单、工作可靠。用它来实现往复运动时，可免去减速装置，并且没有传动间隙，运动平稳，因此在各种机械的液压系统中得到广泛应用。液压缸输出力和活塞有效面积及其两边的压差成正比;液压缸基本上由缸筒和缸盖、活塞和活塞杆、密封装置、缓神装置与排气装置组成。缓神装置与排气装置视具体应用场合而定，其他装置则必不可少。
3.3液压控制调节元件
用来控制液压传动系统中油液的流动方向、压力和流量，以保证液压执行元件和工作装置完成指定工作。
液压传动中用来控制液体压力、流量和方向的元件。其中控制压力的称为压力控制阀，控制流量的称为流量控制阀，控制通、断和流向的称为方向控制阀。
3.4液压辅助元件
保证液压传动系统正常工作。例如油箱、油管、滤油器。
液压辅件是系统的一一个重要组成部分，其合理设计和选用在很大程度上影响液压系统的效率、噪声、温升、工作可靠性等技术性能。主要包括:
3.4.1过滤器
过滤器的作用:滤去油中杂质，维护油液清洁，防止油液污染，保证系统正常工作。
3.4.2蓄能器
蓄能器的作用:
蓄能器是液压系统中储存和释放压力能的装置。
1.作辅助动力源或紧急动力源在工作循环不同阶段需要的流量变化很大时，常采用蓄能器和一个流量较小的泵组成油源。另外当驱动泵的原动机发生故障时，蓄能器可作紧急动力源。
2.保压和补充泄漏需要较长时间保压而泵卸载时，可利用蓄能器释放储存的压力油，补充系统泄漏，保持系统压力。
3.吸收冲击和消除压力脉动在压力冲击处和泵的出口安装蓄能器可吸收压力冲击峰值和压力脉动，提高系统工作的平稳性。
3.4.3油箱
油箱是液压系统中储存液压油用。
油箱的功用:
储存系统所需的足够油液;;
散发油液中的热量;
逸出溶解在油液中的空气; :
沉淀油液中的污物;
对中小型液压系统，泵装置及一些液压元件还安装在油箱顶板上。
3.4.4热交换器
系统能量损失转换为热量以后，会使油液温度升高。若长时间油温过高,油液粘度下降，泄漏增加，密封老化，油液氧化，严重影响系统正常工作。为保证正常工作温度在20~65C，需要在系统中安装冷却器。相反，油温过低，油液粘度过大，设备启动困难，压力损失加大并引起过大的振动。此种情况下系统应安装加热器，将油液温度升高到适合的温度。
3.4.5管件
管件是用来连接液压元件、输送液压油液的连接件。它应保证有足够的强度,没有泄漏,密封性能好，压力损失小，拆装方便。
3.4.6密封装置
密封装置用来防止系统油液的内外泄漏，以及外界灰尘和异物的侵入，保证系统建立必要压力。
3.5液压工作介质
工作介质指传动液体，通常被称为液压油。
3.5.1液压油
液压油引就是利用液体压力能的液压系统使用的液压介质，在液压系统中起着能量传递、系统润滑、防腐、防锈、冷却等作用。对于液压油来说，首先应满足液压装置在工作温度下与启动温度下对液体粘度的要求，由于油的粘度变化直接与液压动作、传递效率和传递精度有关，还要求油的粘温性能和剪切安定性应满足不同用途所提出的各种需求。
3.5.2液压油的要求
质量要求:
1.合适的粘 度和良好的粘温性能，以保证液压元件在工作压力和工作温度发生变化的条件下得到良好润滑、冷却和密封。
2.良好的极压抗磨性， 以保证油泵、液压马达、控制阀和油缸中的摩擦副在高压、高速苛刻条件下得到正常的润滑，减少磨损。
3.优良的抗氧化安定性、水解安定性和热稳定性，以抵抗空气、水分和高温、高压等因素的影响或作用，使其不易老化变质，延长使用寿命。
4.良好的抗泡性 和空气释放值，以保证在运转中受到机械剧烈搅拌的条件下产生的泡沫能迅速消失:并能将混入油中的空气在较短时间内释放出来，以实现准确、灵敏、平稳地传递静压。
5.良好的抗乳化性， 能与混入油中的水分迅速分离，以免形成乳化液，引起液压系统的金属材质锈蚀和降低使用性能。
6.良好的防锈性，以防止金属表面锈蚀。

四、液压传动技术在机械中的应用.
驱动机械运动的机构以及各种传动和操纵装置有多中形式。根据所用的不见和零件，可分为机械的、电气的、气动的、液压的传动装置。经常还将不同的形式组合起来运用一四位一体。由于液压传动具有很多优点，使这种新技术发展的很快。液压传动应用与金属切割机床也不过四五十年的历史。航空工业在1930年以后才开始采用。特别是近二三十年一来液压技术在各种工业中的应用越来越广泛。
1、在机床上，液压传动常应用在以下的- -些装置中
1.1进给 传动装置磨床砂轮架和工作台的进给运动大部分采用液压传动;车床、六角车床、自动车床的刀架或转塔刀架，铣床、刨床、组合机床的工作台等的进给运动也都采用液压传动。这些部件有的要求快速移动，有的要求慢速移动。有的既要求快速移动，也要求慢速移动。这些运动多半要求有较大的调速范围，要求在工作中无级调速;有的要求持续进给，有的要求间歇进给;有的要求在负载变化下速度恒定，有的要求有良好的换向性能等等。所有这些要求都是可以用液压传动来实现的。
1.2往复主题运动传动装置龙i刨床的工作台、牛头刨床或插床的滑枕，由于要求作高速往复直线运动并且要求换向冲击小、换向时间短、能耗低，因此都可以采用液压传动。
1.3仿形装置车床、铣床、刨床上的仿形加工可以采用液压伺服系统来完成。起精度可达0.01-0. 02m。此外，磨床上的成型砂轮修正装置亦可采用这系统。
1.4 辅助装置机床上的夹紧装置、齿轮箱变速操纵装置、丝杆螺母间隙消除装置、垂直移动部件平衡装置、分度装置、工件和刀具装卸装置、工件输送装置等，采用液压传动，有利于简化机床结构，提高机床自动化程度。
1.5静压支承重型机床、高速机床、高精度机床上的轴承、导轨、丝杆螺母机构等处采用液压静支承后，可以提高工作平稳性和运动精度。
2、液压传动技术在工程机械行走驱动中的应用
行走驱动系统是工程机械的重要组成部分。与工作系统相比，行走驱动系统不仅需要传输更大的功率，要求器件具有更高的效率和更长的寿命，还希望在变速调速、差速、改变输出轴旋转方向及反向传输动力等方面具有良好的能力。于是，采用何种传动方式，如何更好地满足各种工程机械行走驱动的需要，-直是工程机械行业所要面对的课题。尤其是近年来，随着我国交通、能源等基础设施建设进程的快速发展，建筑施工和资源开发规模不断扩大，工程机械在市场需求大大增强的同时，更面临着作业环境更为苛刻、工沉条件更为复杂等所带来的挑战，也进一步推动着对其行走驱动系统的深入研究。

液压传动是一种可达到传递动力、增加动力、改变速比等目的的传动方式。液压传动是以液体为工作介质，靠处于密闭容器内的液体静压力来传递力的传动方式，静压力的大小取决于负载，而负载速度的传递是按液体容积变化相等的原则进行的，其速度大小取决于流量；如果忽略损失，液压传动所传递的力与速度无关。
液压传动相比其他传统传动方式优势较为明显：1）功率重量比大，能以较轻的设备重量取得更大的力和转矩；2）惯性小，启动、制动迅速；3）无级调速，调速范围大，低速性能好；4）高响应速度；5）高负载刚度；6）可控性好，易于实现自动化，液压元件位臵可以根据设备需要进行调整。
