电磁阀是用电磁控制的工业设备，是用来控制流体的自动化基础元件，属于执行器，并不限于液压、气动。用在工业控制系统中调整介质的方向、流量、速度和其他的参数。电磁阀可以配合不同的电路来实现预期的控制，而控制的精度和灵活性都能够保证。电磁阀有很多种，不同的电磁阀在控制系统的不同位置发挥作用，常用的是单向阀、安全阀、方向控制阀、速度调节阀等。

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。

TM和HST分析比较
1.装载机作业特点:
(1)边行走边作业，移动中进行作业，行走装置和工作装置同时动作;
(2)循环作业，频繁地起步、前进、后退，不断地加减速;
(3)掘削时低速大驱动力，转移时在路上需高速行驶，所需驱动力和速度变化范围广。
2. TM的缺点:
T/M是变矩器加动力换档变速箱，基本上适应装载机作业特点。因此在装载机上广泛采用。但存在以下不足:
(1)作业时经常在低速大驱动力下工作，此时变矩器效率较低，油耗大;
(2)切入铲土时，发动机负荷大转速降低，不能充分利用发动机功率，作业效率低;
作业装置和行走装置同时工作时，很难使发动机控制在大功率点工作，主要是行走变矩器输出功率难控制调节，过去曾采用滑差式离合器来进行功率调节，但功率损失大。
(3)变矩器变速范围小，因此必须采用动力换档变速箱，作业时需频繁换档(每小时高达1000次)司机劳动强度大,现采用电操纵和微机控制自动换档，价格较贵。
HST的优点:
(1)液压传动元件位置独立，布置方便。其优点是:
1)发动机布置在车辆后部可代替平衡重。在确保稳定性前提下，可降低车重，与相同等级TM车相比，重量降低约10%以上。
2) HST液压部件独立布置，装载机中部没有大部件，空地大，可设计选取合适的轴距和大的折腰角度，轴距减小，使转向半径减小。
3) HST动力传动装置系统，布置位置可放低，使整机重心位置降低,提高稳定性。
4)发动机布置在后部，维修保养方便。
(2) HST在全车速范围内可实现无级变速。其发动机功率利用率好。HST传动综合效率比T/M传动高，油耗较低。
(3) HST行走只需操纵油门踏板就能自动变速，从大牵引力车速范围内平稳地行走而不需换档。前进后退换向只需操纵手柄(或按钮)。如果将换向手柄(或按钮)设置在方向盘上，那么整个行走过程,手可以不离开方向盘，操纵轻便容易，好像驾驶自动换档小汽车,对不熟练的司机很适合。
(4)行走微动性能好。卸载靠近卡车需要微动性能。HST车可通过微动踏板，改变变量泵斜盘倾角，使车速平稳连续变化。
(5) HST具有制动效果，能防止在坡度上下滑，料场上作业容易。因此HST车在坡道上行驶，操纵很简单，下坡时放油门踏板，上坡时踩油门踏板。另外，行驶时制动器使用频率大大减少，可延长制动器使用寿命，同时行车安全性提高。
(6)掘起力和行走驱动力匹配好。装载机在铲装过程要求行走驱动力和掘起力配合，就如同人工挖土时手和脚的配合。行走驱动力要求能克服阻力插入料堆。当铲斗碰上大石块或切入土砂过深，装载机不能前进，这时希望轮胎不要相对地面滑转，使轮胎过早磨损。
掘削取土时，工作油缸作用力应能克服作用在斗尖上的垂直力(铲起力)和水平阻力(行走插入力)。轮胎驱动力过大，工作油缸不能使铲斗掘起，则无法取土。应使行走驱动力和工作油缸力保持恰当关系，需检出工作油缸负荷压;力来控制HST的油路大压力(安全阀压力)。铲装时，工作油缸压力高了，HST油路压力应降低，反之工作油缸压力低了，HST 油路压力要高，以保证铲斗充分切入土砂。HST是全油压驱动机械,行走驱动和工作装置可实现综合控制，使掘起力和行走驱动力合理匹配。TM装载机行走驱动功率难调节，工作装置和行走驱动功率无法合理分配实现综合控制。

装载机液压行走传动系统和操纵系统
1.液压行走传动
系统基本组成
装载机液压行走传动系统。液压行走传动系统由液压泵、液压马达、分动箱和前后驱动桥等组成。
2.液压行走装载
机操纵系统
液压行走装载机操纵系统。它由以下操纵杆和操纵踏板组成:
(1)方向电操纵杆,操纵装载机前进和后退。带锁住装置,能将操纵杆固定在所操纵的位置。操纵时手可以不离开方向盘，用手指操纵。为防止意外走动，方向电操纵杆不在中位，发动机就不能起动。
(2)油门踏板，操纵它就能起步、加速、减速和停车，全车速范围自动变速，操纵简单方便,初学者很容易掌握驾驶。
(3)左右制动踏板，右制动踏板和微动阀连动，操纵此踏板，通过微动阀，改变变量泵先导控制油压，使变量泵排量降低，实现机械微动，使铲装作业时工作装置功率和行走驱动功率匹配良好。
(4)运转模式切换机构。通过它可控制油门开度的大位置。有二种运转模式:通常和柔和，分别有相应不同的油门大开度限位。一般情况采用通常运转模式。夜间作业或市内作业等，要求低噪声场合采用柔和运转模式。该模式大牵引力降低2%左右，对通常装载作业能满足要求。
(5)采用脚踏式停车制动，操纵简单,轻轻踩-下停车制动踏板就能制动。解除停车制动,只须拉一下停车制动解除操纵杆。当停车制动器起作用时，方向电操纵杆即使在前进或后退位置,机械也不会行走。当发动机熄火时，如忘记将停车制动器制动时，会自动报警。

平地机是土方工程中用于整形和平整作业的主要机械，广泛用于公路、机场等大面积的地面平整作业。平地机之所以有广泛的辅助作业能力，是由于它的刮土板能在空间完成6度运动。它们可以单独进行，也可以组合进行。平地机在路基施工中，能为路基提供足够的强度和稳定性。它在路基施工中的主要方法有平地作业、刷坡作业、填筑路堤。平地机是一种高速、高效、高精度和多用途的土方工程机械。它可以完成公路重要内容场、农田等大面积的地面平整和挖沟、刮坡、推土、排雪、疏松、压实、布料、拌和、助装和开荒等工作。是机械工程、矿山建设、道路修筑、水利建设和农田改良等施工中的重要设备。公路路基，是路面的基础，是公路工程的重要组成部分。路基承受由路面传来的交通荷载，是路面的支承结构物，它必须具有足够的强度、稳定性和耐久性。根据地形的不同，公路路基一般采用路堤和路堑两种形式。

对液压油性能的要求
在液压传动中，液压油既是传递动力的介质，又是润滑剂，在部分元件中又起密封作用，系统中的热量也是通过油液扩散出去的，因此又起到散热作用。因此，为保证液压系统可靠、有效、经济地工作，液压油必须保证以下几点要求:1)适当的粘度。粘度是表示油液流动时分子间磨擦阻力的大小。粘度过大时油液流动时阻力大，能量损失大，系统效率降低。此外，主机空载损失加大，温升快且工作温度高，在主泵吸油端易出现“空穴”现象。粘度过小时则不能保证液压元件良好的润滑条件，加剧元件的磨损，泄漏增加，液压系统效率也要降低。2)良好的粘温特性。粘温特性是指油液粘度升降随温度而变化的程度，通常用粘度指数表示。粘度指数越大，液压系统工作中油液粘度随温度升高下降越小，从而使液压系统的内漏不致过大。粘度指数一般不得低于90。3)良好的抗磨性及润滑性。目的是为了降低机械磨擦，保证在不同的压力、速度和温度等条件下都有足够的油膜强度。4)较高的化学反应稳定性能，不易氧化和变质。实践证明，油温每升高10℃，其化学反应速度提高约一倍。抗氧化安定性好的液压油长时间使用不易发生氧化变质，可以保证液压油的正常循环。5)质量应纯净，应尽量减少机械杂质、水分和灰尘等的含量。6)对密封件的影响要小。7)抗乳化性要好，不易引起泡沫。抗乳化性是指油液中混入了水并经搅动后不成为乳化液、水从其中分离出来的能力。抗泡沫性是指油液中混入空气并经搅动后不生成乳状液、气泡从油中分离出来的能力。混入水或空气后降低了液压油的容积模数，可压缩性增大，液压元件动作迟缓，并易产生冲击和振动。8)防锈性能好。液压油覆盖在零件表面，避免其被氧化锈蚀。9)抗剪力安定性好。为改善油液的粘度指数，油液中往往加入聚甲基丙烯酯，聚异丁烯等高分子聚合物，这些物质分子链较长，油液流经液压元件的狭缝时受到很大的剪切作用，往往会使分子断链，油液粘温特性下降。10)燃点、闪点应满足环境温度，挥发性要小，以确保液压油使用安全。

桥式起重机是横架于车间、仓库和料场上空进行物料吊运的起重设备。由于它的两端坐落在高大的水泥柱或者金属支架上，形状似桥。桥式起重机的桥架沿铺设在两侧高架上的轨道纵向运行，可以充分利用桥架下面的空间吊运物料，不受地面设备的阻碍。它是使用范围广、数量多的一种起重机械。
