A4VS0180DFE1Z/30R-PZB25U99力士乐柱塞泵江苏
南京轩创机电贸易有限公司代理销售力士乐A4V,A10V,A11V系列柱塞泵
力士乐A4V柱塞泵变量原理就是通过LS(负载敏感)来控制,当执行元件压力变化时,LS把执行元件的压力情况反馈给泵上的LS阀,LS阀给力士乐A4V柱塞泵变量泵里的柱塞施加压力,改变斜盘的角度,从而实现变量.当系统有多个执行元件时,取压力大的执行元件
变量泵的变量控制我知道的一般有两种形式，1：电控；2液控。电控大多采用电比例信号控制比例阀的开口量，通过变量油缸从而改变斜盘角度达到变量目的。液控形式与电控原理没有本质区别。只是阀的控制形式改为液控。亦称LS。有随动伺服的也有压力反馈控制的。
部分型号，如有什么需要或疑问可来电垂询，谢谢合作！
