濾材最終目的是要選擇一個合適的濾器，其自身的總壓差ΔΡ總在潔凈狀態下對于高壓過濾器不應大于ΔΡ最大=***,對于回油過濾器不應大于ΔΡ最大=***。這個極限值可以保證濾器在實際使用中達到流量及壽命的**化。與濾器規格相關的額定流量很重要。在選擇濾器時，它應比實際上已知的流量大一些：Q額定>Q已知現在就可以檢查一下，預選的濾器是否能滿足實際要求：ΔΡ總≤***(高壓過濾器)以及ΔΡ總≤***(回油過濾器);理論上的總壓差ΔΡ總為空濾殼的壓差和濾芯的壓差之和。此時要注意工作介質的運動粘度和密度，因為后面所列的流量曲線是依據運動粘度ν=30cSt以及密度ρ=***3測得的。下面是近似計算總壓差的公式，只需將運動粘度cSt以及密度kg/dm3的數值填進去即可：Ρ Ρ υΔΡ總= 。ΔΡ濾殼+ . . ΔΡ濾芯0．86 *** 30如果ΔΡ總<ΔΡ最大的條件得到滿足,則表示已選擇到合適的濾器規格。但是，若ΔΡ總>ΔΡ最大，則要用下一個較大規格的濾器來重新進行計算，直至上述條件得到滿足。下面用兩個計算示例來具體說明。示例一：回油過濾器的選擇在一臺液壓設備里，回流的油要用一個濾紙做濾芯的回油過濾器過濾。注意：若在液壓設備里有差動油缸或蓄能器工作，其最大回流量會超過泵送量的好幾倍。我們要以這種回流量作為計算的立足點。已知：Q已知=90升/分鐘 ν已知=32cSt ρ=***; 過濾精度20μm預選:規格RF030,Q額定=110升/分鐘>Q已知根據流量曲線圖求得在額定粘度為30cSt時的壓力損失:ΔΡ濾殼=*** ΔΡ濾芯=***求得實際上的壓力損失為: *** *** 32ΔΡ總= ?***+ ? ?****** *** 30ΔΡ總=***<ΔΡ最大=***此濾器在潔凈狀態下滿足了ΔΡ總≤ΔΡ最大=***的條件,故已選擇到合適的規格,沒有必要進一步計算。本公司經營賀德克濾芯，質量保證，歡迎咨詢洽談 賀德克濾芯,德國賀德克濾芯,賀德克液壓濾芯,賀德克液壓油濾芯,hydac濾芯0063DN003BH3HC 0063DN003BH4HC 0063DN003BHHC 0063DN003BN3HC 0063DN003BN4HC 0063DN003BNHC 0063DN006BH3HC 0063DN006BH4HC 0063DN006BHHC 0063DN006BN3HC 0063DN006BN4HC 0063DN006BNHC 0063DN010BH3HC 0063DN010BH4HC 0063DN010BHHC 0063DN010BN3HC 0063DN010BN4HC 0063DN010BNHC 0063DN025BH3HC 0063DN025BH4HC 0063DN025BHHC 0063DN025BN3HC 0063DN025BN4HC 0063DN025BNHC 0063RN003BNHC 0063RN006BNHC 0063RN010BNHC 0063RN025BNHC 0075D003BH3HC 0075D003BH3HC-V 0075D003BH4HC 0075D003BH4HC-V 0075D003BHHC 0075D003BHHC-V 0075D003BHHC2 0075D003BHHC2-V 0075D003BN3HC 0075D003BN3HC-V 0075D003BN4HC 0075D003BN4HC-V 0075D003BNHC 0075D003BNHC-V 0075D003BNHC2 0075D003BNHC2-V 0075D005BH3HC 0075D005BH3HC-V 0075D005BH4HC 0075D005BH4HC-V 0075D005BHHC 0075D005BHHC-V 0075D005BHHC2 0075D005BHHC2-V 0075D005BN3HC 0075D005BN3HC-V 0075D005BN4HC 0075D005BN4HC-V 0075D005BNHC 0075D005BNHC-V 0075D005BNHC2 0075D005BNHC2-V 0075D010BH3HC 0075D010BH3HC-V 0075D010BH4HC 262354 2056488 0950R010BN3HC-V 0075D010BHHC 0075D010BHHC-V 0075D010BHHC2 0075D010BHHC2-V 0075D010BN3HC 0075D010BN3HC-V 0075D010BN4HC 0075D010BN4HC-V 0075D010BNHC 0075D010BNHC-V 0075D010BNHC2 0075D010BNHC2-V 0075D020BH3HC 0075D020BH3HC-V 0075D020BH4HC 0075D020BH4HC-V 0075D020BHHC 0075D020BHHC-V 0075D020BHHC2 0075D020BHHC2-V 0075D020BN3HC 0075D020BN3HC-V 0075D020BN4HC 0075D020BN4HC-V 0075D020BNHC 0075D020BNHC-V 0075D020BNHC2 0075D020BNHC2-V 0075D025WNHC 0075D025WNHC-V 0075D050WNHC 0075D050WNHC-V 0075D100WHC 0075D100WHC-V 0075D200WHC 0075D200WHC-V 0075R003BN3HC 0075R003BN3HC-V 0075R003BN4HC 0075R003BN4HC-V 0075R003BNHC 0075R003BNHC-V 0075R005BN3HC 0075R005BN3HC-V 0075R005BN4HC 0075R005BN4HC-V 0075R005BNHC 0075R005BNHC-V 0075R010BN3HC 0075R010BN3HC-V 0075R010BN4HC 0075R010BN4HC-V 0075R010BNHC 0075R010BNHC-V 0075R020BN3HC 0075R020BN3HC-V 0075R020BN4HC 0075R020BN4HC-V 0075R020BNHC 0075R020BNHC-V 0080MA003BN 0080MA003P 0080MA005BN 0080MA010BN 0080MA010P 0080MA020BN 0080MA020P 0085MA003BN 0085MA003P 0085MA005BN 0085MA010BN 0085MA010P 0085MA020BN 0085MA020P 0090MA003BN 0090MA003BN-V 0090MA003P 0090MA003P-V 0090MA005BN 0090MA005BN-V 0090MA010BN 0090MA010BN-V 0090MA010P 0090MA010P-V 0090MA020BN 0090MA020BN-V 0090MA025P 0090MA025P-V 0095D003BH3HC 0095D003BH3HC-V 0095D003BH4HC 賀德克濾芯,德國賀德克濾芯,賀德克液壓濾芯,賀德克液壓油濾芯,hydac濾芯0095D003BH4HC-V 0095D003BHHC 0095D003BHHC-V 0095D003BHHC2 0095D003BHHC2-V 0095D003BN3HC 0095D003BN3HC-V 0095D003BN4HC 0095D003BN4HC-V 0095D003BNHC 0095D003BNHC-V 0095D003BNHC2 0095D003BNHC2-V 0095D005BH3HC 0095D005BH3HC-V 0095D005BH4HC 0095D005BH4HC-V 0095D005BHHC 0095D005BHHC-V 0095D005BHHC2 0095D005BHHC2-V 0095D005BN3HC 0095D005BN3HC-V 0095D005BN4HC 0095D005BN4HC-V 0095D005BNHC 0095D005BNHC-V 0095D005BNHC2 0095D005BNHC2-V 0095D010BH3HC 0095D010BH3HC-V 0095D010BH4HC 0095D010BH4HC-V 0095D010BHHC 0095D010BHHC-V 0095D010BHHC2 0095D010BHHC2-V 0095D010BN3HC 0095D010BN3HC-V 0095D010BN4HC 0095D010BN4HC-V 0095D010BNHC 0095D010BNHC-V 0095D010BNHC2 0095D010BNHC2-V 0095D020BH3HC 0095D020BH3HC-V 0095D020BH4HC 0095D020BH4HC-V 0095D020BHHC 0095D020BHHC-V 0095D020BHHC2 0095D020BHHC2-V 0095D020BN3HC 0095D020BN3HC-V 0095D020BN4HC 0095D020BN4HC-V 0095D020BNHC 0095D020BNHC-V 0095D020BNHC2 0095D020BNHC2-V 0095D025WNHC 0095D025WNHC-V 0095D050WNHC 0095D050WNHC-V 0095D100WHC 0095D100WHC-V 0095D200WHC 0095D200WHC-V 0095MA003BN 0095MA003BN-V 0095MA003P 0095MA003P-V 0095MA005BN 0095MA005BN-V 0095MA010BN 0095MA010BN-V 0095MA010P 0095MA010P-V 0095MA020BN 0095MA020BN-V 0095MA025P 0095MA025P-V 0100DN003BH3HC 0100DN003BH3HC/-V 0100DN003BH4HC 0100DN003BH4HC/-V 0100DN003BHHC 0100DN003BHHC/-V 0100DN003BN3HC 0100DN003BN3HC/-V 0100DN003BN4HC 0100DN003BN4HC/-V 0100DN003BNHC 0100DN003BNHC/-V 0100DN005BH3HC 0100DN005BH3HC/-V 0100DN005BH4HC 0100DN005BH4HC/-V 0100DN005BHHC 賀德克濾芯,德國賀德克濾芯,賀德克液壓濾芯,賀德克液壓油濾芯,hydac濾芯0100DN005BHHC/-V 0100DN005BN3HC 0100DN005BN3HC/-V 0100DN005BN4HC 0100DN005BN4HC/-V 0100DN005BNHC 0100DN005BNHC/-V 0100DN006BH3HC 0100DN006BH4HC 0100DN006BHHC 0100DN006BN3HC 0100DN006BN4HC 0100DN006BNHC 0100DN010BH3HC 0100DN010BH3HC/-V 0100DN010BH4HC'
