一、用環(huán)氧樹脂成形的無機(jī)纖維
二、納污量大
三、具有三維迷宮式構(gòu)造，深度過濾，對(duì)于細(xì)微的顆粒有很高的分離度
四、有優(yōu)異的價(jià)格/性能比
我公司濾芯依照下述國際標(biāo)準(zhǔn)檢驗(yàn)：
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(qiáng)度
四、ISO/DIS 4572 多次通過試驗(yàn)
五、ISO 2942 質(zhì)量保證（氣泡試驗(yàn)）
六、ISO 3723 端蓋負(fù)載試驗(yàn)
七、ISO 2941 破裂試驗(yàn)
濾芯的評(píng)定：
評(píng)定過濾器的最重要的準(zhǔn)則是β值。此值是按照國際標(biāo)準(zhǔn)ISO/DIS 4572用所謂多次通過試驗(yàn)來測(cè)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(dǎo)出一個(gè)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

過濾器最佳規(guī)格的確定
在進(jìn)行計(jì)算之前，首先要了解下述參數(shù)：
一、 要求濾器達(dá)到的最大流量Q已知（升/分鐘）
二、 工作介質(zhì)的運(yùn)動(dòng)粘度υ已知（mm2/S或cSt）
三、 工作介質(zhì)的密度ρ
四、 過濾精度μm
五、 濾材
最終目的是要選擇一個(gè)合適的濾器，其自身的總壓差ΔΡ總在潔凈狀態(tài)下對(duì)于高壓過濾器不應(yīng)大于ΔΡ最大=***,對(duì)于回油過濾器不應(yīng)大于ΔΡ最大=***。這個(gè)極限值可以保證濾器在實(shí)際使用中達(dá)到流量及壽命的最佳化。
與濾器規(guī)格相關(guān)的額定流量很重要。在選擇濾器時(shí)，它應(yīng)比實(shí)際上已知的流量大一些：
Q額定>Q已知
現(xiàn)在就可以檢查一下，預(yù)選的濾器是否能滿足實(shí)際要求：ΔΡ總≤***(高壓過濾器)以及
ΔΡ總≤***(回油過濾器);理論上的總壓差ΔΡ總為空濾殼的壓差和濾芯的壓差之和。此時(shí)要注意工作介質(zhì)的運(yùn)動(dòng)粘度和密度，因?yàn)楹竺嫠械牧髁壳€是依據(jù)運(yùn)動(dòng)粘度ν=30cSt以及密度ρ=***3測(cè)得的。下面是近似計(jì)算總壓差的公式，只需將運(yùn)動(dòng)粘度cSt以及密度kg/dm3的數(shù)值填進(jìn)去即可：
Ρ Ρ υ
ΔΡ總= 。ΔΡ濾殼+ . . ΔΡ濾芯
0．86 *** 30
如果ΔΡ總<ΔΡ最大的條件得到滿足,則表示已選擇到合適的濾器規(guī)格。但是，若ΔΡ總>
ΔΡ最大，則要用下一個(gè)較大規(guī)格的濾器來重新進(jìn)行計(jì)算，直至上述條件得到滿足。
下面用兩個(gè)計(jì)算示例來具體說明。
示例一：回油過濾器的選擇
在一臺(tái)液壓設(shè)備里，回流的油要用一個(gè)濾紙做濾芯的回油過濾器過濾。
注意：若在液壓設(shè)備里有差動(dòng)油缸或蓄能器工作，其最大回流量會(huì)超過泵送量的好幾倍。我們要以這種回流量作為計(jì)算的立足點(diǎn)。
已知：Q已知=90升/分鐘 ν已知=32cSt ρ=***; 過濾精度20μm
預(yù)選:規(guī)格RF030,Q額定=110升/分鐘>Q已知
根據(jù)流量曲線圖求得在額定粘度為30cSt時(shí)的壓力損失:
ΔΡ濾殼=*** ΔΡ濾芯=***
求得實(shí)際上的壓力損失為: *** *** 32
ΔΡ總= ?***+ ? ?***
*** *** 30
ΔΡ總=***<ΔΡ最大=***
此濾器在潔凈狀態(tài)下滿足了ΔΡ總≤ΔΡ最大=***的條件,故已選擇到合適的規(guī)格,沒有必要進(jìn)一步計(jì)算。
