什么是 DFE (動(dòng)態(tài)過濾效率試驗(yàn)?)
所有的液壓潤滑系統(tǒng)都有一個(gè)被最敏感的元件, 比如伺服閥
或高速軸承等元件限定的而不是界定的嚴(yán)格的污染度等級, 元件
生產(chǎn)廠商根據(jù) ISO4406 或 ISO4406: 1999 提供了流體的污染度等
級. 要求有好的性能和最長的壽命. 污染度等級決定了個(gè)體元
件的磨損率(使用壽命) 并且能盡可能使用的像預(yù)期的那么好.
系統(tǒng)設(shè)計(jì),過濾性能和維護(hù)很大地決定了系統(tǒng)的污染度等級,
過濾器被希望保持在公差等級以下, 在運(yùn)轉(zhuǎn)中系統(tǒng)的過濾器性能
基于流速，流動(dòng)密度，流速的變化，粘度，頻率，污染度等級，
注入速度和其他的幾個(gè)條件。
所有的過濾器都受限于系統(tǒng)的動(dòng)態(tài)形式，
液壓系統(tǒng)過濾器遇到流
速上的頻率和快速變化伴有頻率的變化。潤滑系統(tǒng)在啟動(dòng)和關(guān)機(jī)過程中有典型的動(dòng)態(tài)狀態(tài)。過濾
器的兩個(gè)主要特性是截留率和存留率。 截留率是過濾器捕獲顆粒的效率，而存留率是一種過濾
器如何保存住捕獲住的顆粒的效率。 一個(gè)過濾器不是黑洞，它的過濾效率不一定只基于它捕獲
的顆粒效率。如果設(shè)計(jì)不當(dāng)， 一只過濾器有可能變成最危險(xiǎn)的污染源。
動(dòng)態(tài)過濾效率試驗(yàn)（DFE）是液壓潤滑過濾器性能測試的一個(gè)變革，DFE 試驗(yàn)比當(dāng)前工業(yè)更
先進(jìn)一步，它通過減少動(dòng)態(tài)負(fù)荷循環(huán)，并在循環(huán)前，循環(huán)中和循環(huán)后進(jìn)行測量實(shí)際的性能來彌補(bǔ)
了實(shí)驗(yàn)室和實(shí)際應(yīng)用之間的鴻溝。DFE 試驗(yàn)使實(shí)際使用中的截留率和存留率合格了，因此我們
能夠預(yù)測最糟糕的流體清潔度平均的清潔度。DFE 試驗(yàn)方法是 Scientific Services Inc(SSI)和
Hy-Pro Filtration 聯(lián)合首創(chuàng)于 1998.
現(xiàn)行過濾器測試方法
過濾器總成和濾芯的生產(chǎn)廠商在理想的實(shí)驗(yàn)室條件采用工業(yè)標(biāo)準(zhǔn)測試過濾效率和納污能力。
該測試方法是在 1999 年根據(jù) IS04572 更新為 IS016889 多次通過試驗(yàn)協(xié)議。此協(xié)議提供重復(fù)測試
方法，在不同測試的情況下時(shí)相同的濾芯產(chǎn)生
同樣的過濾效率。 MIL-H-5606
液壓油在一個(gè)閉環(huán)系統(tǒng)以恒定流量進(jìn)行
測試濾芯，而且在過濾器前后都裝有
顆粒計(jì)數(shù)器。在上游顆粒計(jì)數(shù)器前加入
一定量的污染物。一小部分流體被過濾;
然后通過過濾器前和后的顆粒計(jì)數(shù)器
計(jì)算出過濾效率。過濾效率是在一定的
污染顆粒（Xµ[C]）下通過下述關(guān)系公式
的 Beta 值來表示:
根據(jù) ISO16889 的過濾效率 Beta 值:
βX[C]= 上游≥Xµ[C]污染顆粒數(shù)量
下游≥Xµ[C]污染顆粒數(shù)量
如β7[c]=600/4=150, 過濾效率（Beta）：β7[c]=150
過濾效率也可表示為百分比：
β7[c]=150=（
β-1）/β×100，過濾比效率β7[c]=150=（150-1）/150×100=99.33%
該過濾器在過濾 7µ[c]或更大的顆粒下過濾效率為 99.33%
