賀德克HYDAC濾芯為什么比普通液壓油濾芯壽命長(zhǎng)

賀德克濾芯比普通液壓油濾芯壽命長(zhǎng)的原因，濾芯的損耗過(guò)程，主要是污染物對(duì)濾芯的堵塞。 污染物加載一個(gè)濾芯污染物加載過(guò)程就是堵塞濾芯通孔的過(guò)程。當(dāng)濾芯被污染顆粒堵住時(shí)，能夠通過(guò)液流的孔減少，要保證通過(guò)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(guò)濾芯的壓差增長(zhǎng)很慢，堵塞的孔對(duì)整個(gè)壓力損失影響很小?？墒?，當(dāng)堵塞孔達(dá)到一個(gè)值時(shí)，堵塞非常迅速，在這一點(diǎn)，通過(guò)濾芯的壓差上升非常快。一個(gè)濾芯濾材孔的數(shù)量、尺寸、形狀和分布表明了為何一個(gè)濾芯比另一個(gè)濾芯壽命長(zhǎng)的原因。
對(duì)于一給定厚度和過(guò)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(dāng)液流通過(guò)濾芯是，各個(gè)濾層濾除不同尺寸的顆粒，后層濾材中小的孔不會(huì)被大的顆粒堵塞，這些后層濾材的小孔仍然過(guò)濾流體中大量的小顆粒。0480D003BN/HC 0480D005BN/HC 0480D010BN/HC 0480D020BN/HC 0480D003BN3HC 0480D005BN3HC 0480D010BN3HC0480D020BN3HC 0480D003BN4HC 0480D005BN4HC 0480D010BN4HC 0480D020BN4HC 0480D020P 0480D020W
