供應(yīng)質(zhì)量上乘的0480D010BN4HC賀德克高壓濾芯,提醒大家應(yīng)注意賀德克濾芯的損耗和保養(yǎng)問(wèn)題賀德克濾芯的損耗過(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。
可是,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???。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?qū)τ谝唤o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。
