PUROLATOR液壓油1300EAR032N1濾芯

納污量是指在試驗過程中過濾材料的壓力降達到規定的數量值時，單位面積的過濾材料所能容納的顆粒污染的重量。濾芯孔經通道易受顆粒污染物的淤積滯留，使其壓差增大，當壓差達到規定的zui大極限值時，使用壽命終止。
濾芯壽命終止的zui直接的參數反映就是濾芯上下游的壓差達到了旁通閥開啟的壓力， 此時濾芯的納污容量也達到了zui大值，如果在設計和制造濾芯時考慮提高濾芯的納污能力，也就是提高了濾芯的壽命。

濾芯的工藝參數方面
1、波高、波數及過濾面積液壓油濾芯
在濾芯外形尺寸已經確定的前提下!改變波高，波數等工藝參數盡可能的增加濾材有效過濾面積， 可以減小單位濾材表面的通量和增加整個濾芯的納污量，提高濾芯壽命。通過增加濾芯的過濾面積，濾芯的使用壽命增加的往往增加的更快，如果波數增加太多，擁擠的折疊波會降低波與波之間的液壓油流動空間，使得濾芯壓差增加! 達到濾芯壓差報警的時間便短，壽命降低。 一般使波間距保持在1.5-2.5mm 為宜。
