力士乐REXROTH径向柱塞泵PR4-3X/2.50-700RA01M0
径向柱塞泵可分为阀配流与轴配流两大类。阀配流径向柱塞泵存在故障率高、效率低等缺点。国际上70、80年代发展的轴配流径向柱塞泵克服了阀配流径向柱塞泵的不足。由于径向泵结构上的特点,固定了轴配流径向柱塞泵比轴向柱塞泵耐冲击、寿命长、控制精度高。变量行程短泵的变量是在变量柱塞和限位柱塞作用下,改变定子的偏心距实现的,而定于的最大偏心距为 5—9mm(根据排量大小不同),变量行程很短。且变量机构设计为高压操纵,由控制阀进行控制。故该泵的响应速度快。径向结构设计克服了如轴向柱塞泵滑靴偏磨的问题。使其抗冲击能力大幅度提高。

泵安装:
  1、泵安装的好坏,对泵的平稳运行和使用寿命有很重要的影响,所以安装校正工作必须仔细地进行,不得草率行事。
  2、泵吸入管的安装高度、长度和管径应满足计算值,力求简短,减少不必要的损失(如弯头等);并保证泵在工作时,不超过其允许汽蚀余量。
  3、吸入和排出管路应该有支架。泵不允许承受管路的负荷。
  4、安装泵的地点应足够宽敞,以方便检修工作。
  安装顺序:
  1、将机组放在埋有地脚螺栓的基础上,在底座与基础之间,用成对的楔垫用校正用。
  2、松开联轴大,用水平仪分别放在泵轴和底座上,通过调整楔垫,校正机组水平,适当拧紧地脚螺栓,以防走动。
  3、校正泵轴和电机轴的同心度,在联轴大路外圆上,允许偏差0.1毫米;两联轴器平面的间隙应保证2~4毫米,(小泵取小值)间隙要均匀,允差0.3毫米。
  4、在接好管路及确定电动机转动方向后,再接上联轴器,并再校核一遍轴的同心芳。
  5、在机组实际试运行2~3小时后,作最后检查,如无不良现象,则认为安装合格。在试运过程中检查轴承的温度和振动情况如下:
  6、在安装过程中,为防止杂物落入机器内,机组的所有孔眼均应盖好。
  7、为防止管线中杂物进入泵内,对新安装的管线,在泵胶应装设过滤器,其有效截面应大于吸入管截面的2~3倍。

常用液压名称\名词解释
电磁阀通常与单作用气动执行机构配套使用,两位是两个位置可控:开-关,三通是有三个通道通气,一般情况下1个通道与气源连接,另外两个通道1个与执行机构的进气口连接,1个与执行机构排气口连接,具体的工作原理可以参照单作用气动执行机构的工作原理图。
两位五通电磁阀通常与双作用气动执行机构配套使用,两位是两个位置可控:开-关,五通是有五个通道通气,其中1个与气源连接,两个与双作用气缸的外部气室的进出气口连接,两个与内部气室的进出气口接连,具体的工作原理可参照双作用气动执行机构工作原理
在气路(或液路)上来说,两位三通电磁阀具有1个进气孔(接进气气源)、1个出气孔(提供给目标设备气源)、1个排气孔(一般安装一个消声器,如果不怕噪音的话也可以不装@_@)。 两位五通电磁阀具有1个进气孔(接进气气源)、1个正动作出气孔和1个反动作出气孔(分别提供给目标设备的一正一反动作的气源)、1个正动作排气孔和1个反动作排气孔(安装消声器)。
对于小型自动控制设备,气管一般选用8~12mm的工业胶气管。在电气上来说,两位三通电磁阀一般为单电控(即单线圈),两位五通电磁阀一般为双电控(即双线圈)。线圈电压等级一般采用DC24V、AC220V等。 两位三通电磁阀分为常闭型和常开型两种,常闭型指线圈没通电时气路是断的,常开型指线圈没通电时气路是通的。 常闭型两位三通电磁阀动作原理:给线圈通电,气路接通,线圈一旦断电,气路就会断开,这相当于“点动”。 常开型两位三通单电控电磁阀动作原理:给线圈通电,气路断开,线圈一旦断电,气路就会接通,这也是“点动”。 两位五通双电控电磁阀动作原理:给正动作线圈通电,则正动作气路接通(正动作出气孔有气),即使给正动作线圈断电后正动作气路仍然是接通的,将会一直维持到给反动作线圈通电为止。 给反动作线圈通电,则反动作气路接通(反动作出气孔有气),即使给反动作线圈断电后反动作气路仍然是接通的,将会一直维持到给正动作线圈通电为止。这相当于“自锁”。 基于两位五通双电控电磁阀的这种特性,在设计机电控制回路或编制PLC程序的时候,可以让电磁阀线圈动作1~2秒就可以了,这样可以保护电磁阀线圈不容易损坏。
REXROTH电磁阀,德国力士乐电磁阀,Rexroth电磁阀电磁阀在液路系统中用来实现液路的通断或液流方向的改变,它一般具有一个可以在线圈电磁力驱动下滑动的阀芯,阀芯在不同的位置时,电磁阀的通路也就不同。阀芯的工作位置有几个,该电磁阀就叫几位电磁阀:阀体上的接口,也就是电磁阀的通路数,有几个通路口,该电磁阀就叫几通电磁阀。 电磁阀安装后,一般所有接口都应该是连接好了的,所谓工作位置指的是阀芯的位置。阀芯在线圈不通电时处在甲位置,在线圈通电时处在乙位置,阀芯在不同位置时,对各接口起到或接通或封闭的作用。
电磁阀二位是指电磁阀的阀芯有两个不同的工作位置(开、关)。 电磁阀二通、三通指电磁阀的阀体上有两个、三个通道口; 比如二位二通电磁阀是一进一出(二个通道、最普通常见) 二位三通电磁阀控制液体是一进二出(两出分别是一个常开一个常闭);气动换向电磁阀是一进一出一排气;液压一进一出一回油。
国内外的电磁阀从原理上分为三大类(即:直动式、分步直动式、先导式),而从阀瓣结构和材料上的不同与原理上的区别又分为六个分支小类(直动膜片结构、分步重片结构、先导膜式结构、直动活塞结构、分步直动活塞结构、先导活塞结构)。
直动式电磁阀:
原理:通电时,电磁线圈产生电磁力把关闭件从阀座上提起,阀门打开;断电时,电磁力消失,弹簧把关闭件压在阀座上,阀门关闭。
特点:在真空、负压、零压时能正常工作,但通径一般不超过25mm。
分布直动式电磁阀:
原理:它是一种直动和先导式相结合的原理,当入口与出口没有压差时,通电后,电磁力直接把先导小阀和主阀关闭件依次向上提起,阀门打开。当入口与出口达到启动压差时,通电后,电磁力先导小阀,主阀下腔压力上升,上腔压力下降,从而利用压差把主阀向上推开;断电时,先导阀利用弹簧力或介质压力推动关闭件,向下移动,使阀门关闭。
特点:在零压差或真空、高压时亦能可*动作,但功率较大,要求必须水平安装。
先导式电磁阀:
原理:通电时,电磁力把先导孔打开,上腔室压力迅速下降,在关闭件周围形成上低下高的压差,流体压力推动关闭件向上移动,阀门打开;断电时,弹簧力把先导孔关闭,入口压力通过旁通孔迅速腔室在关阀件周围形成下低上高的压差,流体压力推动关闭件向下移动,关闭阀门。

液压阀是一种用压力油操作的自动化元件,它受配压阀压力油的控制,通常与电磁配压阀组合使用,可用于远距离控制水电站油、气、水管路系统的通断。 用于降低并稳定系统中某一支路的油液压力,常用于夹紧、控制、润滑等油路。有直动型与先导型之分,多用先导型。

?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。
压力控制阀 按用途分为溢流阀﹑减压阀和顺序阀。(1)溢流阀:能控制液压系统在达到调定压力时保持恒定状态。用於过载保护的溢流阀称为安全阀。当系统发生故障,压力升高到可能造成破坏的限定值时,阀口会打开而溢流,以保证系统的安全。(2)减压阀:能控制分支回路得到比主回路油压低的稳定压力。减压阀按它所控制的压力功能不同,又可分为定值减压阀(输出压力为恒定值)﹑定差减压阀(输入与输出压力差为定值)和定比减压阀(输入与输出压力间保持一定的比例)。(3)顺序阀:能使一个执行元件(如液压缸﹑液压马达等)动作以后,再按顺序使其他执行元件动作。油泵产生的压力先推动液压缸1运动,同时通过顺序阀的进油口作用在面积A 上,当液压缸1运动完全成后,压力升高,作用在面积A 的向上推力大於弹簧的调定值后,阀芯上升使进油口与出油口相通,使液压缸2运动。
流量控制阀 利用调节阀芯和阀体间的节流口面积和它所产生的局部阻力对流量进行调节,从而控制执行元件的运动速度。流量控制阀按用途分为 5种。(1)节流阀:在调定节流口面积后,能使载荷压力变化不大和运动均匀性要求不高的执行元件的运动速度基本上保持稳定。(2)调速阀:在载荷压力变化时能保持节流阀的进出口压差为定值。这样,在节流口面积调定以后,不论载荷压力如何变化,调速阀都能保持通过节流阀的流量不变,从而使执行元件的运动速度稳定。(3)分流阀:不论载荷大小,能使同一油源的两个执行元件得到相等流量的为等量分流阀或同步阀;得到按比例分配流量的为比例分流阀。(4)集流阀:作用与分流阀相反,使流入集流阀的流量按比例分配。(5)分流集流阀:兼具分流阀和集流阀两种功能。
方向控制阀 按用途分为单向阀和换向阀。单向阀:只允许流体在管道中单向接通,反向即切断。换向阀:改变不同管路间的通﹑断关系﹑根据阀芯在阀体中的工作位置数分两位﹑三位等;根据所控制的通道数分两通﹑三通﹑四通﹑五通等;根据阀芯驱动方式分手动﹑机动﹑电动﹑液动等。三位四通换向阀的工作原理。P 为供油口,O 为回油口,A ﹑B 是通向执行元件的输出口。当阀芯处於中位时,全部油口切断,执行元件不动;当阀芯移到右位时,P 与A 通,B 与O 通;当阀芯移到左位时,P 与B 通,A 与O 通。这样,执行元件就能作正﹑反向运动。
60年代后期,在上述几种液压控制阀的基础上又研制出电液比例控制阀。它的输出量(压力﹑流量)能随输入的电信号连续变化。电液比例控制阀按作用不同,相应地分为电液比例压力控制阀﹑电液比例流量控制阀和电液比例方向控制阀等。
