，我们要知道，负载敏感系统中，通过节流阀的流量是不随负载压力的改变而变化的，它仅仅和阀口开度的大小成比例。
操作节流阀（实际应用中为方向控制阀组）改变其阀口开度大小，便可以改变泵输出的流量大小，使其与负载所需流量相适应。
当节流阀阀口开度一定时，负载的变化不会影响进入执行元件的流量。
下面我们详细分析上述两个过程：
1、负载运动速度需要改变时（负载压力大小不变），只需调节节流阀阀口开度，观察负载敏感泵的自动调节过程
当节流阀的阀口变化时，动态压差ΔP将会大于或小于负载敏感泵的弹簧预紧力P弹，此时负载敏感阀的阀芯受力处于不平衡状态，为了恢复到受力平衡状态，负载敏感阀的阀芯会向左或向右移动，负载敏感阀的阀芯的左右移动就会改变泵的排量，从而使泵的输出流量Q 变大或变小，重新使稳定压差ΔP= P弹 =定值。其具体过程如下： 力士乐 比例阀 武汉
A：节流阀阀口开度减小，动态压差ΔP变大（即阀口对液流 武汉的节流作用将有所增大），流动阻力的增大被负载敏感阀的滑阀所感受到，滑阀左端压力P增大，滑阀会向右移动一段距离，此时压力油被引到主控制活塞缸的无杆腔，在压力油的作用下，控制活塞左移，泵的斜盘倾角变小，流量变小，动态压差ΔP变小（参考小孔流量公式），直到动态压差ΔP=P弹时，阀芯受力平衡，泵的斜盘倾角不再变化，此时泵输出的流量与节流口进口的流量相匹配；
