賀德克hydac液壓濾芯0330R005BN4HC
hydac濾芯的損耗過程，主要是污染物對濾芯的堵塞。污染物加載一個濾芯污染物加載過程就是堵塞濾芯通孔的過程。當濾芯被污染顆粒堵住時，能夠通過液流的孔減少，要保證通過濾材的流量，壓差就要增大。
在初始階段，由于濾材上有許多孔，通過濾芯的壓差增長很慢，堵塞的孔對整個壓力損失影響很小?？墒?，當堵塞孔達到一個值時，堵塞非常迅速，在這一點，通過濾芯的壓差上升非?？?。一個濾芯濾材孔的數量、尺寸、形狀和分布表明了為何一個濾芯比另一個濾芯壽命長的原因。www.kpdly.com
對于一給定厚度和過濾精度的濾材，濾紙比玻纖濾材的孔少，因此，濾紙材料的濾芯就比玻纖濾材的濾芯堵塞快。多層玻纖濾材的濾芯能夠容納更多的污染物，當液 流通過濾芯是，各個濾層濾除不同尺寸的顆粒，后層濾材中小的孔不會被大的顆粒堵塞，這些后層濾材的小孔仍然過濾流體中大量的小顆粒。
