WE-2SP-M12X1 R928028410柱塞式电子放大器

特点:

-适用于控制4WRA类型,公称规格尺寸6和10的2X系列和WRZ 7X系列比例阀

-装配在欧洲格式100*160mm结构形式的印制板中,适合安装在机架中。

-控制值输入:

差动输入±10V

四个控制值输入,启动电压为±10V

电流输入4至20mA

-通过24V输入或跳线改变内部控制值信号较性

-通过相位识别(24V输入)或斜坡时间启动(24V输入)选择斜坡时间

 

配套的板卡机架:

-19英寸机架类型VT19101,VT19102,VT19103和VT19110

-VT12302类型全封闭式板卡机架仅供在控制柜中安装

-配套的供电单元:

-VT-NE30-2X类型,紧凑型电源115/230VAC→24VDC,108VA

放大器板卡具有一个带输入电流限制器的电源。这便提供了所有内部正

电源电压和负电压电压。输入电流限制器可防止由电流输出级中的滤波

电容器引起的输入电流峰值。

通过将对差动输入端口施加的外部控制值,对加法器和斜坡函数发生器

施加的控制值相加来形成内部控制值信号。

供油过程   

当凸轮轴转到凸轮的凸起部分顶起滚轮体时，柱塞弹簧被压缩，柱塞向上运动，燃油受压，一部分燃油经油孔流回喷油泵上体油腔。当柱塞顶面遮住套筒上进油孔的上缘时，由于柱塞和套筒的配合间隙很小(0.0015-0.0025mm)使柱塞顶部的泵油室成为一个密封油腔，柱塞继续上升，泵油室内的油压迅速升高，泵油压力>出油阀弹簧力 高压油管剩余压力时，推开出油阀，高压柴油经出油阀进入高压油管，通过喷油器喷入燃烧室。回油过程   

柱塞向上供油，当上行到柱塞上的斜槽(停供边)与套筒上的回油孔相通时，泵油室低压油路便与柱塞头部的中孔和径向孔及斜槽沟通，油压骤然下降，出油阀在弹簧力的作用下迅速关闭，停止供油。此后柱塞还要上行，当凸轮的凸起部分转过去后，在弹簧的作用下，柱塞又下行。此时便开始了下一个循环。

液压放大器利用节流原理，用输入位移(转角)信号对通往执行元件的液体流量或压力进行控制，是一个机械-液压转换装置。由于控制阀输入功率小而输出功率大，因此也是-种功率放大元件。它加上转换器及反馈机构组成同服阀，是伺服系统的核心元件。

在液压伺服系统中，通常液压放大器以其输出的较大功率液流驱动执行机构工作，执行机构则将液压能转换为机械能去推动负载。

比例阀的输入单元是电-机械转换器,它将输入的电信号转换成机械量转换器有伺服电机和步进电机力马达和力矩马达比例电磁铁等形式。但常用的比例阀大都采用了比例电磁铁，比例电磁铁根据电磁原理设计,能使其产生的机械量(力或力矩和位移)与输入电信号(电流)的大小成比例,再连续地控制液压阀阀芯的位置，进而实现连续地控制液压系统的压力方向和流量。比例电磁铁的结构，它由线圈、衔铁推杆等组成,当有信号输入线圈时,线圈内磁场对衔铁产生作用力,衔铁在磁场中按信号电流的大小和方向成比例连续地运动,再通过固连在一起的销钉带动推杆运动,从而控制滑阀阀芯的运动。
