固安縣晴空濾芯廠賀德克液壓油濾芯一、用環(huán)氧樹脂成形的無機纖維

二、納污量大

三、具有三維迷宮式構造，深度過濾，對于細微的顆粒有很高的分離度

四、有優(yōu)異的價格/性能比

我公司濾芯依照下述國際標準檢驗：

一、ISO 2943   與液壓介質(zhì)的相容性

二、ISO 3968   流量特性曲線

三、ISO/DIS 3724   流通疲勞強度

四、ISO/DIS  4572   多次通過試驗

五、ISO 2942    質(zhì)量保證（氣泡試驗）

六、ISO 3723    端蓋負載試驗

七、ISO 2941    破裂試驗

濾芯的評定：

評定過濾器的最重要的準則是β值。此值是按照國際標準ISO/DIS 4572用所謂多次通過試驗來測得的。

定義：  β值是指上游液體中大于給定尺寸x的顆粒數(shù)與下游液體中大于相同的給定尺寸x的顆粒數(shù)的比值。

        Nv          Nv=過濾前的尺寸大于x的顆粒數(shù)

  βx=              Nh=過濾后的尺寸大于x的顆粒數(shù)

        Nh          X=顆粒尺寸

根據(jù)β值的定義可以很容易地推導出一個公式，用此公式可以求得某種濾材分離大于一定尺寸的顆粒的效率：                                          β值/過濾效率比值

     βx-1                                              β值         過濾效率

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