电液换向阀
电液换向阀是用控制油路中的压力油推动阀芯,变换流体流动方向的控制阀
电液换向阀是电磁换向阀和液控换向阀的组合,它是用电磁换向阀控制液控换向阀的动作,变换流体流动方向的控制阀。
电液换向阀和液控换向阀主要用在流量超过电磁换向阀正常工作允许范围的液压系统中,对执行元件的动作进行控制,或对油液的流动方向进行控制。
说明事项
1.产品可任意安装,优先考虑水平位置。
2.液压系统所用介质必c须过滤,过滤精度至少20μm。
3.固定螺钉请按样本中所列参数选用。
4.与阀连接的表面,粗糙度要求Ra0.8,平面度要求0.01/100mm
工作原理:。。当两个电磁阀线圈通电时,平衡孔回路关闭,泄流孔回路打开,活塞上腔泄压,活塞上行,阀门打开。反之,活塞下行,阀门关闭。在阀门开启和关闭过程中,可将流量(流速)信号及阀塞位置信号传送给计算机,经过计算机处理后发出相应的指令,控制两个电磁导阀的通、断电状态,使活塞的上下腔的液压差产生变化,从而将活塞控制在所需的开启高度上,实现对管道介质流量的控制。
阀门安装
(1)阀用联接螺钉的性能等级必须符合制造厂的要求,不得随意代换。联接螺钉应均匀拧紧(勿用锤子敲打或强行扳拧),不要拧偏,较后使阀的的安装平面与底板或油路块安装平面全部接触。
(2)应注意进油口与回油口的方位,某些阀如将进油口与回油口装反,会造成事故。有些阀件为了安装方便,往往开有同作用的两个孔,安装后不用的一个要封堵。
(3)液压阀的安装方式应符合制造厂及系统设计图样中的规定。
(4)板式阀或插装阀必须有正确的定向措施。
(5)为了保证安全,阀的安装必须考虑重力、冲击、振动对阀内主要零件的影响。
(6)方向阀一般应保持轴线水平安装;
(7)一般需调整的阀件(如流量阀、压力阀等),顺时针方向旋转时,增加流量、压力,逆时针方向旋转时,则减少流量、压力。

普通电磁阀使用开关式电磁铁
衔铁与线圈的相对位置决定阀芯是受推力还是拉力
电磁铁包括开关式和比例式两种,开关式电磁铁常被安装在换向阀上,用来控制阀的换向、系统的卸荷和加载等;比例式电磁铁安装在各类比例阀上,用来控制液流的方向、压力和流量。不少比例压力阀安装在电控变量泵上,可以控制泵的和流量和方向。

怎么处理电磁阀的故障
电磁阀线圈的额定电压有DC12V、DC24V、AC24V(50/60Hz)、AC110V(50/60Hz)、AC220V(50/60Hz)、AC380V(50/60Hz)。一般在电气设计时要么采用AC220V(不需加装开关电源,成本低、线路简单而便于维护)、要么采用DC24V(常用的的安全电压、开关电源/电磁阀线圈都易于维修更换)。
检测电磁阀好坏的方法:先给电磁阀通上被控制的介质(带压力的液体、气体<空气>,压力值为电磁阀使用压力范围的中间值),再给电磁阀线圈通电,如果被控制介质有从通到断或从断到通的状态的变化,那么电磁阀就是好的,否则就是有问题的。
