REXROTH 0811404701 力士乐电磁比例阀  力士乐REXROTH比例阀，REXROTH阀工作原理

REXROTH力士乐比例阀其实缺点较多：能耗浪费大、容易出故障、抗污染能力差、价格昂贵等等等等，好处只有一个：动态性能是所有液压阀中较高的。就凭着这一个优点，在很多对动态特性要求高的场合不得不使用伺服阀，如飞机火箭的舵机控制、汽轮机调速等等。动态要求低一点的，基本上都是比例阀的天下了。 

一般说来，好像伺服系统都是闭环控制，比例多用于开环控制；其次比例阀类型要多，有比例压力、流量控制阀等，控制比伺服药灵活一些。从他们内部结构看，伺服阀多是零遮盖，比例阀则有一定的死区，控制精度要低，向应要慢。但从发展趋势看，特别在比例方向流量控制阀和伺服阀方面，两者性能差别逐渐在缩小，另外比例阀的成本比伺服阀要低许多，抗污染能力也强！ 

伺服阀与比例阀的区别 

REXROTH力士乐比例阀与比例阀之间的差别并没有严格的规定，因为比例阀的性能越来越好，逐渐向伺服阀靠近，所以近些年出现了比例伺服阀。 

力士乐REXROTH比例阀，REXROTH阀工作原理REXROTH力士乐比例阀非要说差别，主要体现在一下几点： 

伺服阀中位没有死区，比例阀有中位死区； 

伺服阀的频响（响应频率）更高，可以高达200Hz左右，比例阀一般较高几十Hz； 

伺服阀对液压油液的要求更高，需要精过滤才行，否则容易堵塞，比例阀要求低一些。 

REXROTH力士乐比例伺服阀性能介于伺服阀和比例阀之间。 

REXROTH力士乐比例换向阀属于比例阀的一种，用来控制流量和流向。

力士乐REXROTH比例阀，REXROTH阀工作原理

力士乐Rexroth比例阀在使用过程中,应注意对感载比例阀的检查调整.当感载弹簧过松时,后轮制动力就会减小,此时应调整感载弹簧,但不可调得过紧,否则会使后轮制动力太大而失去侧向控制能力,发生甩尾。正确的调整方法是.在平坦的地面上使车身落地,车辆空载,调整感载弹簧,使杠杆与活塞间无间隙即可.在有条件的情况下,可采用准确的调整方法.通过测量前后轮制动管路压力,绘制压力分配特性曲线,确认调整是否合格。

德国Rexroth力士乐比例阀的工作原理，REXROTH力士乐比例阀结构，力士乐比例阀作用

REXROTH力士乐比例阀当左侧受力大于右侧受力与感载弹簧预紧力之和时（此时的压力为Ps）,活塞不断右移,较后使阀门与阀座接触而关闭,将输入输出油路隔绝,达到平衡状态。P1若进一步升高时,则活塞左移,阀门再度打开,制动液流入出油口,使P2也升高。

德国rexroth比例阀VT-NE30-2X的输入压力为零.即.;时,输出腔的压力通过比例阀皮圈凸筋间空酸从唇口泄去高压,同时,当比例阀芯所受的弹簧力大于向右的液压力时,比例阀弹簧将比例阀芯推回原始位置,使比例阀芯与比例阀皮圈内孔完全分离而完全泄压.此时输入输出压力为零.随着输入压力.加大,即左加大,使比例滑阀单向力平衡遭破坏.当<>&;6-时,比例阀芯左移与比例阀皮圈产生间隙形成节流并混合比倒阀常见的故障为:1,输入输出压力同步.2,低压时辅人输出压力同步,高压时输入输出压力正常.3,低压时输入输出压力正常,高压时输入输出压力不正常.,1994.№为零时为混合比倒圉工作性能试验示意图.试验时,先将管内的空气排净,然后分别取低,中,高三个压力进行试验,输入辅出压力符合即为合格。

Rexroth力士乐比例阀奥迪四轮驱动轿车制动系统在关闭ABS后,感载比例阀可用于防止后轮的过制动。当汽车直线行驶时,两后轮的制动压力可根据车辆载荷增减;当汽车左转弯时,左后轮载荷下降,由于感载比例阀位于左后轮附近,可同样起作用使两后轮的制动压力都下降.而当汽车右转弯时,右后轮载荷减小,汽车的侧向加速度使感载比例阀起作用,降低右后轮的制动压力。这样的自动调节使前、后轮的制动力分配和左、右后轮的制动力分配都接近理想的制动力分配,从而提高了制动安全性。

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较佳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‘.其结构主要由较靴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、气隙和较靴1，形成回路口较靴对衔铁产生吸力门在线圈中电流一定时。吸力的大小因较靴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。
