REXROTH力士乐比例溢流阀比例溢流阀工作原理是:
比例溢流阀工作原理是:比例溢流阀通过弹簧力的大小改变溢流压力大大小变化,比例电磁铁作用在弹簧上的力可以按比例调整,所以就输入信号变化比例溢流阀的压力也会变化。
普通溢流阀与比例溢流阀一样,都有一个阀芯,阀芯的一端是液压油产生的压力,另一端是机械力。普通溢流阀通过调节弹簧力,来调整液压压力。而比例溢流阀是电磁铁直接产生推力,作用在阀芯上,电磁铁上的输入电压可以在0-24伏之间变化,产生的推力就随之变化,从而得到连续变化的液压压力。
因为比例电磁铁的推力不大,所以直动式比例溢流阀的流量很小,压力70兆帕时,流量只有1升/分钟左右。需要大流量比例阀的时候,要把这个比例阀做先导阀,还要配一个大通径的溢流阀。
