多層復合折疊黎明液壓濾芯是安裝在過濾器殼體中檢測液體壓降流量特性的。清潔過濾器的總壓降由過濾器殼體和液壓油濾芯兩部分產生。黎明液壓濾芯的檢測結果來看，過濾器空殼在壓降流量檢測中產生的壓力損失較大，清潔液壓油濾芯的壓力損失較小。由此可見，清潔過濾器的總I-k降主要由濾殼產生。是黎明液壓濾芯壓降一流量曲線。由于過濾器殼體的報警壓差為0.35 M Pa，因而選擇最終結束壓差為0.35 MPa國產化濾芯   濾芯型號：LH0060D3BN/HC、LH0060D5BN/HC、LH0060D10BN/HC、LH0060D20BN/HC，LH0110D3BN/HC、LH0110D5BN/HC、LH0110D10BN/HC、LH0110D20BN/HC，LH0160D3BN/HC、LH0160D5BN/HC、LH0160D10BN/HC、LH0160D20BN/HC，LH0240D3BN/HC、LH0240D5BN/HC、LH0240D10BN/HC、LH0240D20BN/HC，LH0330D3BN/HC、LH0330D5BN/HC、LH0330D10BN/HC、LH0330D20BN/HC，LH0500D3BN/HC、LH0500D5BN/HC、LH0500D10BN/HC、LH0500D20BN/HC，LH0660D3BN/HC、LH0660D5BN/HC、LH0660D10BN/HC、LH0660D20BN/HC，LH0060R1BN/HC、LH0060R3BN/HC、LH0060R5BN/HC、LH0060R10BN/HC、LH0060R20BN/HC、LH0060R30BN/HC，LH0110R1BN/HC、LH0110R3BN/HC、LH0110R5BN/HC、LH0110R10BN/HC、LH0110R20BN/HC、LH0110R30BN/HC，LH0160R1BN/HC、LH0160R3BN/HC、LH0160R5BN/HC、LH0160R10BN/HC、LH0160R20BN/HC、LH0160R30BN/HC，LH0240R1BN/HC、LH0240R3BN/HC、LH0240R5BN/HC、LH0240R10BN/HC、LH0240R20BN/HC、LH0240R30BN/HC，LH0330R1BN/HC、LH0330R3BN/HC、LH0330R5BN/HC、LH0330R10BN/HC、LH0330R20BN/HC、LH0330R30BN/HC，LH0500R1BN/HC、LH0500R3BN/HC、LH0500R5BN/HC、LH0500R10BN/HC、LH0500R20BN/HC、LH0500R30BN/HC，LH0660R1BN/HC、LH0660R3BN/HC、LH0660R5BN/HC、LH0660R10BN/HC、LH0660R20BN/HC、LH0660R30BN/HC，LH0850R1BN/HC、LH0850R3BN/HC、LH0850R5BN/HC、LH0850R10BN/HC、LH0850R20BN/HC、LH0850R30BN/HC，LH0950R1BN/HC、LH0950R3BN/HC、LH0950R5BN/HC、LH0950R10BN/HC、LH0950R20BN/HC、LH0950R30BN/HC，LH1300R1BN/HC、LH1300R3BN/HC、LH1300R5BN/HC、LH1300R10BN/HC、LH1300R20BN/HC、LH1300R30BN/HC
