电磁阀之所以归划于自动化仪表行业中的执行器部分，虽外表与其他-些手动阀相似，甚至略显粗糙,但内部结构却十分精细，与一般手动阀门有着本质的区别。打个简单的比喻来说,普通手动阀的开关完全靠人工用力的大小来操作，而电磁阀则完全靠自身的功能达到控制目的，而非人力所为再者电磁阀区别于其他阀门的是因为内部结构不同，所以不同的工作介质不能通用一种阀门，一旦确定介质种类而选定的产品则不能与不同介质混用，否则会导致电磁阀失灵或损坏。

力士乐DA控制是闭式油路纯液压机械控制，是静压自动变速机构。自动驱动控制:使得行驶驱动如自动变速轿车，踩油门起步，操纵油门踏板就能改变静压传动流量，改变车速。防失速控制:自动调整液压泵吸收功率，在过载时会自动减少泵的排量，例如:当行驶阻力增大时和当作业装置工作消耗部分功率时，能防止发动机熄火和失速。
其特点是液压泵和油门踏板之间无直接联系，不需要任何操纵装置和电子装置,液压泵的控制是完全自动的。DA控制经许多年和成千台不同机械使用考核(叉车、装载机和其它车辆)，证明了其可靠性、耐久性，也验证了其独特概念的正确性。

DA控制油路及基本工作原理
DA控制油路符号原理，踏油门踏板,发动机转速上升，其带动的补油泵转速随之上升，其流量成比例增加。该泵流量由转速感应阀(带测量节流孔的DA阀)检出。通过DA阀的流量越大,则液压泵的排量越大，泵输出流量增大，车速随之提高。作用在斜盘变量机构上的力。
1.控制压力
发动机带动的补油泵输出油液经测量节流口产生压降AP,经DA控制阀放大后产生控制压力P3o经节流口流量Q和压降AP、控制压力P3的关系。影响控制压力曲线的因素:控制压力的大小与DA阀的结构(放大倍数)、调节状态、节流孔及补油泵流量(转速、效率)有关。
一般可变的参数为:调节状态和节流孔的大小;补油泵的效率基本上对其影响很小。
(1)节流孔
根据节流口直径及补油泵流量可以确定节流口前后的压差:因此，借助于改变节流口的直径就可以改变控制压力曲线的“陡度”，作为经验数值:一般节流口直径改变1/10mm时，控制压力曲线的调节终点大约改变100rpmo。
(2) DA阀的调节
利用改变DA阀中调节弹簧预紧力的大小也可以使控制压力特性曲线产生平移;从其力平衡方程式中也可以很容易地看出:弹簧预紧力的提高，会导致控制压力的下降，反之亦然。
这样，对于驱动泵的调节也就意味着:拧入调节螺钉会使控制压力下降，调节起始，点就会随之，上升(车辆在较高转速时才会启动!)。
2.变量油缸活塞弹簧回到中位的作用力
在回位弹簧作用下，油泵回到中位零排量，将油泵从零变至大排量需克服弹簧力。例如:当控制压力为5bar 时，斜盘开始变量，到控制压力为15bar时，泵处于大排量。
3.与油泵输出油压有关的反推力
反推力取决于配流盘上的高压配流口位置。在完全对称的情况下(配流盘无偏转)，使斜盘正偏转及负偏转的分力a和b大小相等。同理低压侧也如此，由于低压侧所产生的使斜盘偏转的力(或称力矩)相比之下很小，可以忽略，在这种情况下，由泵的高压侧所产生的对斜盘的作用力是平衡的(a=b)。
如将配流盘沿着传动轴的旋转方向偏转一个角度B,则a>b,作用在斜盘上的反推力会使斜盘向零排量位置回摆，变排量时控制压力需克服此推力。
(1)对压力增益曲线的影响
斜盘倾角接近零时，变量油泵对中弹簧不起主要作用，主要靠时钟调节(配流盘高压窗口偏离中心位置的角度)影响压力增益曲线。
(2)对流量特性曲线的影响
其影响与泵输出压力大小有关，随着输出压力增大影响增大。

2.步进(微动)功能
通过人工调节改变DA控制来实现步进功能，可实现与发动机转速无关的，由人工来控制的行走速度，在工作装置需要发动机高转速大流量时，行走装置却可低速行驶，实现合理的功率分配。
(1)通过手柄(或踏板)人工操纵改变DA阀的弹簧力来调节控制压力
(2)在DA阀输出的控制油路上连接人工机械操纵，可调节式回油节流阀来改变控制压力P3
(3)在DA阀输出的控制油路上连接人工机械操纵，可调式减压阀或人工液压操纵(例制动油压)可调式减压阀。
油门控制踏板和微动阀可调杠杆通过机械连杆机构相连。由于该机构存在空行程S (可调节)，因此在发动机小油门时，油门操纵微动阀可调杠杆不动，当油门到达一定位置(发动机转速一定)， 空行程消除，继续加大油门，将带动微动阀可调杠杆转动，DA阀弹簧力增大，控制压力下降，这样当发动机油门开度(转速)到达一定位置，油泵排量不会随之增大，行走泵负，荷得到限制。2000rpm 到达大排量，2000-2500rpm 时(负荷不增大)力士乐称为“部分步进”。

DA控制车辆的工作特性
DA控制车辆的所有工作点都在三维曲面上,分析以下三种典型行驶工况，就能了解其工作原理: 
1.车辆加速工况
(1)原地起步时，发动机械低怠速状态，DA 泵在零排量;
(2)踩油门，发动机转速上升开始建立压力，但由于不能克服行走阻力，车辆尚未起步;
(3)加大油门踏板，车辆克服行驶阻力，起步行走;
(4)继续加大油门，发动机转速升高，油泵排量增加，车速提高; 
(5)当车辆接近大车速油压略降低，因无进一步加速需要，车辆只需克服摩擦阻力。
2.车辆爬坡工况.
(1)在平地上以大车速行驶(液压泵全排量大流量),压力相应于克服其滚动阻力和风阻力;
(2)进入坡道，所需牵引力增加,液压系统压力上升，发动机输出动力增加，转速下降，DA阀使液压泵排量减小，按所需牵引力增加的大小，发动机功率和液压泵功率取得新的平衡。
3.车辆失速状态(例:装载机以一定车速插入料堆进行铲装)
(1)在平地上以一定车速前进，克服行驶阻力，产生一定油压;
(2)接触料堆,所需牵引力增加，油压提高，同时压力感应DA泵使油泵排量下降，防止发动机过载;
(3)完全功入料堆，系统油压进- -步提高，发动机随负荷增加，转速进一步降低;
(4)系统压力达设定值，DA泵压力切断功能，使油泵排量降低至能保持系统大油压(相应于大牵引力)的状态，同时使得系统不过热。

装载机液压行走系统
HST装载机是全液压驱动机械，行走和工作装置可实现综合控制。目前，新开发的小型装载机几乎已100%采用HST,并有向大型装载机发展的趋势。与传统的液力机械装载机相比，具有很大的优势。

挖掘机械一般由动力装置、传动装置、行走装置和工作装置等组成。单斗挖掘机和斗轮挖掘机还有转台，多斗挖掘机还有物料输送装置。动力装置有柴油机、电动机、柴油发电机组或外电源变流机组。柴油机和电动机大多用于中、小型挖掘机械，用一台原动机集中驱动，两者可互换。柴油发电机组和外电源变流机组用于大、中型挖掘机械，用多台电机分散驱动。行走装置主要用来支承机器、使机器变换工作位置和转移作业场地；另外，链斗式挖掘机和环轮式挖掘机的铲斗，随着行走装置的连续行走而切削土壤。行走装置有履带式、轮胎式、步行式、轨行式、浮游式和拖挂式等几种。作业场地固定、要求接地比压较低时用履带式；作业场地多变时用轮胎式；因施工条件特殊而必须架设专用轨道时，用轨行式；挖掘水下泥土用浮游式；小型单斗挖掘机的行走装置无动力源时，用拖挂式；作业场地固定、机器重量大时，用步行式。步行式行走装置大多用于单斗挖掘机中的大、中型拉铲挖掘机和斗轮挖掘机。

工作装置是液压挖掘机的主要组成部分，挖掘机配置的是反铲工作装置，它主要用于挖掘停机面以下的土壤，但也可以挖掘*大切削高度以下的土壤，除了可以挖坑、开沟、装载外还可以进行简单平整场地工作。挖掘作业适应于开挖Ⅰ~Ⅳ级土，Ⅴ级以上用液压锤或需爆破手段。反铲工作装置由动臂、斗杆、铲斗、摇杆、连杆及包含动臂油缸、斗杆油缸、铲斗油缸在内的工作装置液压管路等主要部分组成。

铲土运输机械是利用刀型或斗型切削装置在走行中铲掘、切削土石方，并能把所铲削的土石方送到一定距离自行卸掉的机械，也包括专门用于越野运输的自卸运输车辆。属于工程机械的一大类别。铲土运输机械由装械机、推土机、平地机、铲运机及矿用载重自卸车五大类组成。

铲土运输机械包括推土机、单斗装载机、 铲运机和平地机等机种，能完成刮削、铲运、装卸和 堆积散粒物料，平整场地，以及露天矿剥离等土石方 工程。依靠牵引力和速度进行作业，故对机械的行 走装置和牵引传动系有较高要求。常用柴油机驱 动，采用机械、液力机械或液压传动传递牵引功率。 行走装置有轮胎式和履带式，工作装置多采用液压 操纵。近年来，向大型化和超小型化发展;并研究自 控、遥控技术的应用，以扩大机械使用范围，提高在 地下、水下和高原等恶劣条件下的作业能力;进行节 能和降低公害，提高机械的安全性和舒适性的研究， 以改善机械性能。

推土机是一种能够进行挖掘、运输和排弃岩土的土方工程机械,在露天矿有广泛的用途。例如，用于建设排土场,平整汽车排土场，堆集分散的矿岩，平整工作平盘和建筑场地等。它不仅用于辅助工作，也可用于主要开采工作。例如:砂矿床的剥离和采矿，铲运机和犁岩机的牵引和助推，在无运输开采法时配合其他土方机械降低剥离台阶高度等。

推土机是一种工程车辆。前方装有大型的金属推土刀，使用时放下推土刀，向前铲削并推送泥、沙及石块等，推土刀位置和角度可以调整，能单独完成挖土、运土和卸土工作。
推土机是土方工程机械的一种主要机械，按行走方式分为履带式和轮胎式两种。

装载机是一种广泛用于公路、铁路、建筑、水电、港口、矿山等建设工程的土石方施工机械，它主要用于铲装土壤、砂石、石灰、煤炭等散状物料，也可对矿石、硬土等作轻度铲挖作业。换装不同的辅助工作装置还可进行推土、起重和其他物料如木材的装卸作业。
在道路、特别是在高等级公路施工中，装载机用于路基工程的填挖、沥青混合料和水泥混凝土料场的集料与装料等作业。此外还可进行推运土壤、刮平地面和牵引其他机械等作业。由于装载机具有作业速度快、效率高、机动性好、操作轻便等优点，因此它成为工程建设中土石方施工的主要机种之一。
装载机的铲掘和装卸物料作业是通过其工作装置的运动来实现的。装载机工作装置由铲斗、动臂、连杆、摇臂和转斗油缸、动臂油缸等组成。整个工作装置铰接在车架7上。铲斗通过连杆和摇臂与转斗油缸铰接，用以装卸物料。动臂与车架、动臂油缸铰接，用以升降铲斗。铲斗的翻转和动臂的升降采用液压操纵。
装载机作业时工作装置应能保证：当转斗油缸闭锁、动臂油缸举升或降落时，连杆机构使铲斗上下平动或接近平动，以免铲斗倾斜而撒落物料；当动臂处于任何位置、铲斗绕动臂铰点转动进行卸料时，铲斗倾斜角不小于45°，卸料后动臂下降时又能使铲斗自动放平。
装载机主要部件包括发动机，变矩器，变速箱，前、后驱动桥，简称四大件1. 发动机2. 变矩器上有三个泵，工作泵（供应举升，翻斗压力油）转向泵（供应转向压力油）变速泵也称行走泵（供 应变矩器，变速箱压力油），有些机型转向泵上还装有先导泵（供应操纵阀先导压力油）3..工作液压油路，液压油箱，工作泵，多路阀，举升油缸和翻斗油缸4. 行走油路：变速箱油底壳油，行走泵，一路进变矩器一路进档位阀，变速箱离合器5. 驱动：传动轴，主差速器，轮边减速器6. 转向油路：油箱，转向泵，稳流阀（或者优先阀）转向器，转向油缸7. 变速箱有一体的（行星式）和分体（定轴式）两种。
