0630DN003BN4HC賀德克液壓油濾芯，0630DN003BN4HC賀德克液壓油濾芯安裝在液壓系統的油路中用于清除液壓系統中各元件磨損的金屬粉末及其它機械雜質使油路保持清潔，延長液壓系統壽命。濾芯濾層采用不復合玻璃纖維濾材，強度高，耐高溫耐腐蝕，納污容量大，過濾性能好。濾芯內支撐網為1.5MM厚螺旋焊接圓孔網，支撐力大，抗壓力強。

影響賀德克濾芯壽命的因素主要有三個：

濾芯過濾性能

1、過濾精度：過濾精度是指過濾材料對不同尺寸顆粒污染物的濾除能力。

一般認為過濾精度高，濾芯的壽命較短。

2、納污量

　　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，當壓差達到規定值時，使用壽命終止。

　　濾芯壽命終止的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。

3、濾芯的工藝參數方面

波高、波數及過濾面積

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。
