一、调节可以是连续、无级的，也可以在液压系统工作过程中---车地进行。
二、通过改变排量实现调速成为容积调速，这种方法和另一种所谓的节-速相比，功率损失小，避免了系统-，很适合大功率系统。
三、容积式泵刚性的压力-流量特性对液压传动虽然是很-的，但是往往和流量调节的要求有矛盾，因而有---将容积式泵的原始压力-流量特性加以改造。这就是变量调节机构的任务。
四、威格士叶片泵中推动变量机构动作的动力源及控制方式是多种多样的，但大体上可以分层两类：

1、一类是由外力或外部信号对变量机构进行直接调节或控制；
2、另一类是用泵本身的流量、压力、功率等工作参数作为信号，通过改变和控制泵的排量，实现对其流量、压力、功率的反馈控制，进行自动调节。

2、在尽量缩短威格士叶片泵管路长度的同时可减少管路压力损失和振动等，要采取避免因温升产生的管路热伸长而拉断、拉裂管路，并注意接头部位的。
3、和软管一样，在靠近接头的部位需要有一段直线部分。
4、弯曲长度要适量，不能斜交。

5、 防止威格士叶片泵系统液压冲击带来的泄漏。产生液压冲击时，会导致接头螺母松动而产生漏油。
6、此时，一方面应重新拧紧接头螺母，另一方面要找出产生液压冲击的原因并设法予以防止。例如设置蓄能器等吸振，采用缓冲阀等缓冲组件消振等。
7、威格士叶片泵负压产生的泄漏。对瞬时流速大于10m/s的管路，均可能产生瞬间负压(真空)现象，如果接头没有采用防止负压产生的密封结构形式，
负压产生时会吸走威格士叶片泵内的o形密封圈，压力上来时因无o形密封圈而产生泄漏。
