賀德克濾芯0005L003BN4，賀德克濾芯0005L003BN4用于液壓、潤(rùn)滑系統(tǒng)的過(guò)濾，濾除工作介質(zhì)中的固體顆粒及膠狀物質(zhì)，有效控制系統(tǒng)的污染度，保障系統(tǒng)的安全高效運(yùn)行。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(guò)濾性能好。
HYDAC賀德克濾芯的使用壽命是實(shí)際液壓系統(tǒng)的一個(gè)重要問(wèn)題，尤其是在高污染工況條件下，濾芯的失效及其由此引起的液壓系統(tǒng)的故障尤為突出。
影響賀德克濾芯壽命的因素主要有三個(gè)：
濾芯過(guò)濾性能
1、過(guò)濾精度：過(guò)濾精度是指過(guò)濾材料對(duì)不同尺寸顆粒污染物的濾除能力。
一般認(rèn)為過(guò)濾精度高，濾芯的壽命較短。
2、納污量
　　納污量是指在試驗(yàn)過(guò)程中過(guò)濾材料的壓力降達(dá)到規(guī)定的數(shù)量值時(shí)，單位面積的過(guò)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(shí)，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(kāi)啟的壓力， 此時(shí)濾芯的納污容量也達(dá)到了大值，如果在設(shè)計(jì)和制造濾芯時(shí)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(guò)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(guò)濾面積， 可以減小單位濾材表面的通量和增加整個(gè)濾芯的納污量，提高濾芯壽命。通過(guò)增加濾芯的過(guò)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(huì)降低波與波之間的液壓油流動(dòng)空間，使得濾芯壓差增加! 達(dá)到濾芯壓差報(bào)警的時(shí)間便短，壽命降低。 一般使波間距保持在1.5-2.5mm 為宜。
