贺德克液压滤芯

液压油滤芯的特点：

1、分高压段用、中压段用、回油段用和吸油段用

2、分高中低精度等级。2—5um为高精度，10—15um为中等精度，15—25um为低精度。

3、为压缩滤芯成品外形尺寸，增大过滤面积，一般滤层部分折成波纹状，液压滤芯打褶高度一般在20㎜ 以下

4、液压滤芯承受压差一般在0.35—0.4MPa，但个别特殊滤芯，要求承受高压差，zui高要求承受32MPa， zhi42MPa等同系统压力。

5、zui高承受温度，有的要求达到135℃

二、对滤芯的要求

1、强度要求，制作完整度要求、承受压差、承受安装外力、承受压差交变载荷

2、通油的顺畅度要求，流量阻力特性

3、耐一定的高温，与工作介质相容

4、滤层纤维不能位移和脱落

5、成承载较多的污物

6、高空及寒冷地区使用正常

7、耐疲劳，交变流量下的疲劳强度

8、滤芯本身清洁度要达标
