     1.pall颇尔滤芯要装在泵的吸油口处：泵的吸油路上一般都安装有表面型滤油器，目的是滤去较大的杂质微粒以保护液压泵，此外滤油器的过滤能力应为泵流量的两倍以上，压力损失小于0.02MPa。
　 2.pall滤芯安装在泵的出口油路上：此处安装滤油器的目的是用来滤除可能侵入阀类等元件的污染物。其过滤精度应为10～15μm，且能承受油路上的工作压力和冲击压力，压力降应小于0.35MPa。同时应安装安全阀以防滤油器堵塞。
　 3.pall滤芯安装在系统的回油路上：这种安装起间接过滤作用。一般与过滤器并连安装一背压阀，当过滤器堵塞达到一定压力值时，背压阀打开。
　 4.pall滤芯安装在系统分支油路上。
　 5.pall滤芯单独过滤系统：大型液压系统可专设一液压泵和滤油器组成独立过滤回路。pall滤芯液压系统中除了整个系统所需的滤油器外，还常常在一些重要元件(如伺服阀、精密节流阀等)的前面单独安装一个专用的精滤油器来确保它们的正常工作。
