0160R005BN3HC替代贺德克油滤芯

固安县晴空滤芯厂贺德克液压油滤芯一、用环氧树脂成形的无机纤维

二、纳污量大

三、具有三维迷宫式构造，深度过滤，对于细微的颗粒有很高的分离度

四、有优异的价格/性能比

我公司滤芯依照下述检验：

一、ISO 2943   与液压介质的相容性

二、ISO 3968   流量特性曲线

三、ISO/DIS 3724   流通疲劳强度

四、ISO/DIS  4572   多次通过试验

五、ISO 2942    （气泡试验）

六、ISO 3723    端盖负载试验

七、ISO 2941    破裂试验

滤芯的评定：

评定过滤器的重要的准则是β值。此值是按照ISO/DIS4572用所谓多次通过试验来测得的。

定义： β值是指上游液体中大于给定尺寸x的颗粒数与下游液体中大于相同的给定尺寸x的颗粒数的比值。

       Nv         Nv=过滤前的尺寸大于x的颗粒数

 βx=             Nh=过滤后的尺寸大于x的颗粒数

       Nh         X=颗粒尺寸

根据β值的定义可以很容易地推导出一个公式，用此公式可以求得某种滤材分离大于一定尺寸的颗粒的效率：                                         β值/过滤效率比值

    βx-1                                             β值        过滤效率

Ex=         *100    Ex=效率%                        1           0，00%

Βx                                               2           50，00%

晴空滤芯厂生产的所有贺德克玻璃纤维滤芯其名义过滤精度的β值均大于200。  200         99，50%

                                                       1．000      99，90%
