成立于1946年的美國(guó)頗爾公司（Pall Corporation）是全球最大，涉及領(lǐng)域最廣的專門從事過(guò)濾、分離和純化的公司。頗爾的技術(shù)專長(zhǎng)，產(chǎn)品系列和全球網(wǎng)絡(luò)使其成為該市場(chǎng)的世界領(lǐng)先者。公司總部設(shè)于美國(guó)紐約，全球員工逾萬(wàn)人，子公司及生產(chǎn)設(shè)施遍及全球30多個(gè)國(guó)家和地區(qū)。新鄉(xiāng)市隆齊過(guò)濾設(shè)備有限公司已經(jīng)可以從技術(shù)上完全替代進(jìn)口PALL濾芯，質(zhì)量工藝精度等均可以和進(jìn)口相媲美頗爾濾芯。
華豫過(guò)濾替代Pall頗爾濾芯產(chǎn)品，所用濾材分為國(guó)產(chǎn)頂級(jí)濾材和進(jìn)口優(yōu)質(zhì)濾材，玻璃纖維濾紙采用實(shí)驗(yàn)級(jí)高品質(zhì)濾紙，濾芯支撐骨架端蓋均采用加厚且表面經(jīng)過(guò)特殊化學(xué)處理，化學(xué)穩(wěn)定性承壓能力大幅提高。本公司產(chǎn)品經(jīng)過(guò)優(yōu)化具有以下優(yōu)點(diǎn)：
•減小壓力損失
•增大納污能力
•流動(dòng)疲勞穩(wěn)定性
•旁通裝置保護(hù)過(guò)濾器免受損壞
•改善流動(dòng)疲勞穩(wěn)定性
•延長(zhǎng)濾芯使用壽命
•更高的操作可靠性
•改進(jìn)的油清潔度
•提高性能
•降低運(yùn)營(yíng)和維護(hù)成本
更高的納污能力和改進(jìn)流動(dòng)疲勞穩(wěn)定性大幅延長(zhǎng)了濾芯的更換間隔，使機(jī)器可以在更長(zhǎng)的時(shí)間間隔下穩(wěn)定工作。改進(jìn)型的過(guò)濾材料結(jié)構(gòu)，提高納污能力作出了重大貢獻(xiàn)，減少壓力損失和提高壓差穩(wěn)定。改進(jìn)的濾材可以消散靜電，骨架具有最好的抗彎強(qiáng)度，同時(shí)降低壓力損失。
濾芯更高的運(yùn)行可靠性，最大限度地減少機(jī)器突然停機(jī)的風(fēng)險(xiǎn)，以及減少停機(jī)時(shí)間所造成的費(fèi)時(shí)和維修工作。

1.液壓系統(tǒng)過(guò)濾器的介紹 
    過(guò)濾器按其過(guò)濾精度(濾去雜質(zhì)的顆粒大小)的不同，有粗過(guò)濾器、普通過(guò)濾器、精密過(guò)濾器和特精過(guò)濾器    四種，它們分別能濾去大于100μm、10～100μm、5～10μm和1～5μm大小的雜質(zhì)。

2.選用濾油器時(shí)，要考慮下列幾點(diǎn)： 
    (1)過(guò)濾精度應(yīng)滿足預(yù)定要求。 
    (2)能在較長(zhǎng)時(shí)間內(nèi)保持足夠的通流能力。 
    (3)濾心具有足夠的強(qiáng)度，不因液壓的作用而損壞。 
    (4)濾心抗腐蝕性能好，能在規(guī)定的溫度下持久地工作。 
    (5)濾心清洗或更換簡(jiǎn)便。pall濾芯pall濾芯
3.安裝濾油器在液壓系統(tǒng)中的安裝位置通常有以下幾種： 
    (1)要裝在泵的吸油口處： 
    泵的吸油路上一般都安裝有表面型濾油器，目的是濾去較大的雜質(zhì)微粒以保護(hù)液壓泵，此外濾油器的過(guò)濾能力應(yīng)為泵流量的兩倍以上，壓力損失小于0.02MPa。 
    (2)安裝在泵的出口油路上： 
    此處安裝濾油器的目的是用來(lái)濾除可能侵入閥類等元件的污染物。其過(guò)濾精度應(yīng)為10～15μm，且能承受油路上的工作壓力和沖擊壓力，壓力降應(yīng)小于0.35MPa。同時(shí)應(yīng)安裝 
    安全閥以防濾油器堵塞。 
    (3)安裝在系統(tǒng)的回油路上：這種安裝起間接過(guò)濾作用。一般與過(guò)濾器并連安裝一背壓閥，當(dāng)過(guò)濾器堵塞達(dá)到一定壓力值時(shí)，背壓閥打開(kāi)。 
    (4)安裝在系統(tǒng)分支油路上。 
    (5)單獨(dú)過(guò)濾系統(tǒng)：大型液壓系統(tǒng)可專設(shè)一液壓泵和濾油器組成獨(dú)立過(guò)濾回路。 
     液壓系統(tǒng)中除了整個(gè)系統(tǒng)所需的濾油器外，還常常在一些重要元件(如伺服閥、精密節(jié)流閥等)的前面單獨(dú)安裝一個(gè)專用的精濾油器來(lái)確保它們的正常工作。pall濾芯pall濾芯pall濾芯pall濾芯pall濾芯pall濾芯pall濾芯
4.PALL濾芯的技術(shù)工藝： 
(1).濾材由專利纖維和樹脂通過(guò)特有工藝制成。具有固定的空隙結(jié)構(gòu)，濾材無(wú)脫落。被攔截的污染顆粒不會(huì)因壓差和流量的脈動(dòng)而產(chǎn)生“卸料”現(xiàn)象。
(2).采用由表及里、沿流動(dòng)方向逐漸縮小的漸變孔徑結(jié)構(gòu)。分層攔截不同尺寸的污染顆粒。實(shí)現(xiàn)深層納垢。從而大大提高了使用壽命。
(3.)采用螺旋繞帶加強(qiáng)的支撐，保證濾材的穩(wěn)固.
