1.pall濾芯液壓系統過濾器的介紹
過濾器按其過濾精度(濾去雜質的顆粒大小)的不同，有粗過濾器、普通過濾器、精密過濾器和特精過濾器 四種，它們分別能濾去大于100μm、10～100μm、5～10μm和1～5μm大小的雜質。
2.pall濾芯選用濾油器時，要考慮下列幾點：
(1)過濾精度應滿足預定要求。
(2)能在較長時間內保持足夠的通流能力。
(3)濾心具有足夠的強度，不因液壓的作用而損壞。
(4)濾心抗腐蝕性能好，能在規定的溫度下持久地工作。
(5)濾心清洗或更換簡便。
3.pall濾芯安裝濾油器在液壓系統中的安裝位置通常有以下幾種：
(1)pall濾芯要裝在泵的吸油口處：
泵的吸油路上一般都安裝有表面型濾油器，目的是濾去較大的雜質微粒以保護液壓泵，此外濾油器的過濾能力應為泵流量的兩倍以上，壓力損失小于0.02MPa。
(2)pall濾芯安裝在泵的出口油路上：
此處安裝濾油器的目的是用來濾除可能侵入閥類等元件的污染物。其過濾精度應為10～15μm，且能承受油路上的工作壓力和沖擊壓力，壓力降應小于0.35MPa。同時應安裝
安全閥以防濾油器堵塞。
(3)pall濾芯安裝在系統的回油路上：這種安裝起間接過濾作用。一般與過濾器并連安裝一背壓閥，當過濾器堵塞達到一定壓力值時，背壓閥打開。
(4)pall濾芯安裝在系統分支油路上。
(5)pall濾芯單獨過濾系統：大型液壓系統可專設一液壓泵和濾油器組成獨立過濾回路。
pall濾芯液壓系統中除了整個系統所需的濾油器外，還常常在一些重要元件(如伺服閥、精密節流閥等)的前面單獨安裝一個的精濾油器來確保它們的正常工作。
4.PALL濾芯的技術工藝：
(1).濾材由纖維和樹脂通過*工藝制成。具有固定的空隙結構，濾材無脫落。被攔截的污染顆粒不會因壓差和流量的脈動而產生“卸料”現象。
(2).采用由表及里、沿流動方向逐漸縮小的漸變孔徑結構。分層攔截不同尺寸的污染顆粒。實現深層納垢。從而大大提高了使用壽命。
(3.)采用螺旋繞帶加強的支撐，保證濾材的穩固。
