液压系统电液伺服阀的选用

电液伺服阀由电气一机械转换器和液压系统放大器构成,如图1所示。电气一机械转换器是将电信号转换成机械位移;液压放大器是将电气一机械转换器输出的机械位移放大后推动阀芯运动,液压放大器由前置放大级和功率放大级组成,前置放大级采用滑阀、喷嘴挡闆阀或射流管阀,功率级采用滑阀形式。

电液伺服阀分爲单级、二级和三级。单级电液伺服阀直接由力马达或力矩马达驱动滑阀阀芯,用于压力低于6. 3MPa、流量小于4L/min和负载变化小的系统;二级电液伺服阀有两级液压放大器,用于流量小于200L/min的系统;三级电液伺服阀可输出更大的流量和功率。

选用伺服阀要依据伺服阀的特点和系统性能要求。伺服阀最大的弱点是抗污染能力差,过滤器的颗粒粒度必须小于3um。伺服阀侧重应用在动态精度和控制精度高、抗干扰能力强的闭环系统中,对动态精度要求一般的液压系统可用比例阀。

从响应速度优先的原则考虑,伺服阀的前置级优先选择喷嘴挡闆阀,其次是射流管阀,最后是滑阀;从功率考虑,应首先选择射流管阀压力效率和容积效率在70%以上,然后选择滑阀和喷嘴挡闆阀;从抗污染和可靠性方面考虑,射流管阀的通径大,抗污染能力强,可延长系统无故障工作时间;从性能稳定方面考虑,射流管阀的磨蚀是对称的,不会引起零漂,性能稳定,寿命长;滑阀的开口形式一般选择零开口结构;伺服阀规格由系统的功率和流量决定,并留有15%~30%的流量裕度;伺服阀的频宽按照伺服系统频宽的5倍选择,以减少对系统响应特性的影响,但不要过宽,否则系统抗干扰能力减小;伺服阀在安装时,阀芯应处于水平位置,管路采用钢管连接,安装位置尽可能靠近执行器;伺服阀有2个线圈,接法有单线圈、双线圈,串联、并联和差动等方式。使用时要注意;伺服阀正式安装前,管路要接入精密过滤器,用60℃的工作油运行清洗lh;伺服阀若在使用中出现振荡现象,可通过改变管路的长度、连接闆或 液压系统执行器的安装形式消除;爲了减小和消除伺服阀阀芯与阀套的间隙,防止滑阀卡死或堵塞,在伺服阀输入信号上叠加一个高频低幅值的颤振信号。
