    电液比例阀是采用了比例控制技术,介于开关型液压阀和电液伺服阀之间的-种液压元件,在工业生产中获得了广泛的应用,输入的电信号有模拟式和数字式两大类,可以用于控制位置(转角)、速度(转速)、加速度(角加速度)、压力(压差)、力(力矩)等参数。电液比例阀等元件可以组成如下三类控制回路和系统
    (1)电液比例压力控制回路和系统。例如:用于带钢热连轧机卷取机液压辅助系统的电液比例压力控制回路,用于板带轧机辊缝控制的液压推上系统电液比例压力控制回路,用于带材卷取设备恒张力的闭环电液比例压力控制回路;
    (2)电液比例流量控制回路和系统。例如:用于带钢热连轧机精轧机平衡液压系统的电液比例压力控制回路,用于机床微进给的电液比例控制回路,用于旋压机折板机同步的电液比例控制回路,用于电梯的电液比例控制回路;
    (3)电液比例多参数控制回路和系统。例如:用于带钢热连轧机精轧换辊液压系统的电液比例压力控制回路,用于液压缸垂直配置而采用wI型阀芯的比例控制回路,用于热轧钢卷步进链式运输机的速度、加减速度控制回路。

    电液比例阀是阀内比例电磁铁输入电压信号产生相应动作,使工作阀阀芯产生位移,阀口尺寸发生改变并以此完成与输入电压成比例压力、流量输出元件。阀芯位移也可以以机械、液压或电形式进行反馈。电液比例阀具有形式种类多样、容易组成使用电气及计算机控制各种电液系统、控制精度高、安装使用灵活以及抗污染能力强等多方面优点,应用领域日益拓宽。近年研发生产插装式比例阀和比例多路阀充分考虑到工程机械使用特点,具有先导控制、负载传感和压力补偿等功能。它出现对移动式液压机械整体技术水平提升具有重要意义。特别是电控先导操作、无线遥控和有线遥控操作等方面展现了其良好应用前景。

    电液比例阀种类和形式
    电液比例阀包括比例流量阀、比例压力阀、比例换向阀。工程机械液压操作特点,以结构形式划分电液比例阀主要有两类:一类是螺旋插装式比例阀,另一类是滑阀式比例阀。
    滑阀式比例阀又称分配阀,是移动式机械液压系统基本元件之一,是能实现方向与流量调节复合阀。电液滑阀式比例多路阀是比较理想电液转换控制元件,它保留了手动多路阀基本功能,还增加了位置电反馈比例伺服操作和负载传感等先进控制手段。它是工程机械分配阀更新换代产品。
    出于制造成本考虑和工程机械控制精度要求不高特点,--般比例多路阀内不配置位移感应传感器,具有电子检测和纠错功能。,阀芯位移量容易受负载变化引起压力波动影响,操作过程中要靠视觉观察来保证作业完成。电控、遥控操作时更应注意外界千涉影响。近来,电子技术发展,人们越来越多采用内装差动变压器(LDVT)等位移传感器构成阀芯位置移动检测,实现阀芯位移闭环控制。这种由电磁比例阀、位置反馈传感器、驱动放大器和其它电子电路组成高度集成比例阀,具有一定校正功能,可以有效克服一.般比例阀缺点,使控制精度到较大提高。

    电液比例多路阀负载传感与压力补偿技术
    节约能量、降低油温和提高控制精度,同时也使同步动作几个执行元件运动时互不干扰,现较先进工程机械都采用了负载传感与压力补偿技术。负载传感与压力补偿是一一个很相似概念,都是利用负载变化引起压力变化去调节泵或阀压力与流量以适应系统工作需求。负载传感对定量泵系统来讲是将负载压力负载感应油路引至远程调压溢流阀上,当负载较小时,溢流阀调定压力也较小;负载较大,调定压力也较大,但也始终存一定溢流损失。变量泵系统是将负载传感油路引入到泵变量机构,使泵输出压力随负载压力升高而升高(始终为较小固定压差),使泵输出流量与系统实际需要流量相等,无溢流损失,实现了节能。压力补偿是提高阀控制性能而采取一种保证措施。将阀口后负载压力引入压力补偿阀,压力补偿阀对阀口前压力进行调整使阀口前后压差为常值,这样节流口流量调节特性流经阀口流量大小就只与该阀口开度有关,而不受负载压力影响。

    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。

    液压传动已成为现代机械装备与机电产品的重要基础技术,在工业机械领域有着极为广泛的应用。液压系统的应用领域包括:工业生产(锻压机械、注塑机、机床、加工中心、机器人、矿山机械、包装机械等)、行走机械(工程机械、建筑机械、农业机械、汽车等)、航空航天、舰船(船舶及舰艇甲板机械、操作及控制系统)、海洋工程(海洋开发平台、海底钻探、水下作业等)。以国外为例,约95%的工程机械、90%的数控加工中心、95%的自动化生产线均采用液压传动。此外,根据工业机械设备使用的液压系统压力条件不同,可按其额定压力分为低压系统(<6.3MPa)、中压系统(6.3-10MPa)、中高压系统(10-20MPa)和高压系统(>20MPa)。

    液压系统主要由5个部分组成,泵、阀、油缸、马达为核心元件。典型的液压系统由动力元件(主要是液压泵)、控制元件(主要是液压阀)、执行元件(包括液压油缸、液压马达)、辅助元件(包括油箱、过滤器、蓄能器、热交换器)、工作介质(包括矿物油、乳化液、液压油等)5个部分组成,其中泵、阀、油缸、马达的技术难度大、产品附加值高、价值占比较高,是液压系统的核心元件。

    液压泵:主要有柱塞泵、齿轮泵、叶片泵和螺杆泵。其中,柱塞泵、叶片泵属于高压泵,齿轮泵属于低压泵。以柱塞泵为例,其密封工作腔构件为圆柱形的柱塞和缸体,容易得到较高的配合精度,特点是泄漏量小,容积效率高,可以在高压下工作;由于柱塞泵压力高、结构紧凑、效率高、流量调节方便,故在需要高压、大流量、大功率的系统中和流量需要调节的场合,如工程机械、矿山冶金机械、船舶、重型刨床及液压机等设备上广泛应用。
    液压阀:主要分为方向阀、流量阀、压力阀。方向阀用于控制系统中的油流方向,包括换向阀、单向阀等;流量控制阀,用于控制液压系统中油的流量,包括节流阀、调速阀等;压力控制阀,用于控制系统中的油压,包括溢流阀、减压阀、顺序阀等;上述三类阀可组成各种复合阀。
    液压油缸:液压缸由缸体、可移动的活塞和连接活塞的活塞杆组成,缸体两端用端盖进行封闭,端盖可采用螺纹、卡圈、拉杆或焊接等方式与缸体连接;分为双作用式、单作用式、伸缩式。
    液压马达:分为单向、双向液压马达,也分为定量马达与变量马达。

    液压件的批量稳定生产需要企业具有多学科、全方面的技术实力和较为雄厚的资金实力。液压件为精密制造产品,生产工艺复杂、流程工序多、管理难度大,涉及材料力学、机械设计、金属材料、金属工艺学、热处理技术、自动化控制技术等多个学科,需要企业具备较高的研发测试水平、生产工艺控制和过程控制能力,才能大批量生产,并保证产品的质量稳定性。另一方面,液压产品的生产需要前期大规模的固定资产投入,特别是精密加工设备、热处理设备、高压液压件的铸件生产设备、检测设备等,且大量精密生产设备依赖进口,对企业有较高的资金要求。
    液压件制造主要分为铸件生产、机械加工和装配测试三大环节:1)精密铸件的铸造工序:砂处理、制芯→造型→合箱→熔化→浇注→落砂→去冒口→抛丸→打磨→热处理→抛丸等;2)铸件、锻件、棒材的加工工序:粗机械加工→热处理→精机械加工→去毛刺→清洗→防锈等;3)使用标准件及调节元件对液压元件进行组装成品工序:清洗→装配→测试→清洗→喷涂等
