富卓滤芯 WG669滤芯厂家滤油器的类型及特点
按滤芯的材料和结构形式，滤油器可分为网式、线隙式，纸质滤芯式、烧结式滤油器及磁性滤油器等。按滤油器安放的位置不同，还可以分为吸滤器，压滤器和回油滤油器，考虑到泵的自吸性能，吸油滤油器多为粗滤器。
（1）网式滤油器
图4.1所示为网式滤油器，其滤芯以铜网为过滤材料，在周围开有很多孔的塑料或金属筒形骨架上，包着一层或两层铜丝网，其过滤精度取决于铜网层数和网孔的大小。这种滤油器结构简单，通流能力大，清洗方便，但过滤精度低，一般用于液压泵的吸油口。
图4.1网式滤油器
(2)线隙式滤油器
线隙式滤油器如图4.2所示，用钢线或铝线密绕在筒形骨架的外部来组成滤芯，依靠铜丝间的微小间隙滤除混入液体中的杂质。其结构简单，通流能力大，过滤精度比网式滤油器高，但不易清洗，多为回油滤油器。

（3）纸质滤油器
纸质滤油器如图4.3所示，其滤芯为平纹或波纹的酚醛树脂或木浆微孔滤纸制成的纸芯，将纸芯围绕在带孔的镀锡铁做成的骨架上，以增大强度。为增加过滤面积，纸芯一般做成折叠形。其过滤精度较高，一般用于油液的精过滤，但堵塞后无法清洗，须经常更换滤芯。

（4）烧结式滤油器
烧结式滤油器如图4.4所示，其滤芯用金属粉末烧结而成，利用颗粒间的微孔来挡住油液中的杂质通过。其滤芯能承受高压，抗腐蚀性好，过滤精度高，适用于要求精滤的高压、高温液压系统。
