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(tǒng)的油路中用于清除液壓系統(tǒng)中各元件磨損的金屬粉末及其它機(jī)械雜質(zhì)使油路保持清潔，延長液壓系統(tǒng)壽命。濾芯濾層采用不復(fù)合玻璃纖維濾材，強(qiáng)度高，耐高溫耐腐蝕，納污容量大，過濾性能好。濾芯內(nèi)支撐網(wǎng)為1.5MM厚螺旋焊接圓孔網(wǎng)，支撐力大，抗壓力強(qiáng)。

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(rèn)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(dá)到規(guī)定的數(shù)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(jīng)通道易受顆粒污染物的淤積滯留，使其壓差增大，當(dāng)壓差達(dá)到規(guī)定值時，使用壽命終止。

　　濾芯壽命終止的直接的參數(shù)反映就是濾芯上下游的壓差達(dá)到了旁通閥開啟的壓力， 此時濾芯的納污容量也達(dá)到了大值，如果在設(shè)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(shù)方面

波高、波數(shù)及過濾面積

在濾芯外形尺寸已經(jīng)確定的前提下改變波高，波數(shù)等工藝參數(shù)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(shù)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(dá)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。
