1.pall滤芯液压系统过滤器的介绍
过滤器按其过滤精度(滤去杂质的颗粒大小)的不同，有粗过滤器、普通过滤器、精密过滤器
和特精过滤器 四种，它们分别能滤去大于100μm、10～100μm、5～10μm和1～5μm大小的杂质
。
2.pall滤芯选用滤油器时，要考虑下列几点：
(1)过滤精度应满足预定要求。
(2)能在较长时间内保持足够的通流能力。
(3)滤心具有足够的强度，不因液压的作用而损坏。
(4)滤心抗腐蚀性能好，能在规定的温度下持久地工作。
(5)滤心清洗或更换简便。
3.pall滤芯安装滤油器在液压系统中的安装位置通常有以下几种：
(1)pall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。
