A Novel Nylon Nanofiber Media Technology for Hydraulic Filtration(PPT)

摘要

Media History 1.Hydrauiic media history:1.1 System requirements have dramatically changed over the past 30 years,1.2 Beta Ratio requirements have increased;βx = 2 to βx = 75,are now often βx = 1000,1.3 Media selection has been limited to cellulose,cellulose/microglass and microglass.1.4 New option:sub-micron nylon fiber technology integrated with melt blown technology producing a proprietary hydraulic media that meets and exceeds today's hydraulic system requirements.2.1987:Cummins Filtration (CF) initiated melt blowing expioratory research.3.1932:StrataPore~R commercialized in fuel and lube filters.4.2007:CF initiated sub-micron nylon fiber technology research.5.2012:NanoNet~R production began for fuel filters and NanoForce~R in Air.6.2017:NanoNet~R introduced in Lube filters.7.In 2016,CF began exploring the use of its proprietary hydraulic media in hydraulic filters with the goal to release products to the market in 2028.Summary 1.Media design differences:1.1 Proprietary hydraulic media (sub-micron nylon fiber with melt blown technology)-thin efficiency layer,uniform pore structure that utilizes surface/cake and depth filtration to prevent particles from migrating downstream under challenging conditions,1.2 Microglass-thick efficiency layer,less uniform pore structure that uses depth filtration which can potentially release particles down-stream under challenging conditions.2.Differential pressure:2.1 Proprietary hydraulic media offers a reduction in differential pressure while maintaining a high beta ratio.3.Particle removal 3.1 Proprietary hydraulic media beta ratio performance continues to increase under challenging conditions while the microglass media begins to release particles downstream.
