BYPASS KIDNEY-LOOP FILTRATION TECHNOLOGY DELIVERS HUGE DIVIDENDS

摘要

Being a "green" company is nothing new to CCECO Oil & Filtration, based in Kent, Wash. A recent push for the company to enlarge its distributor network emphasized its green initiative by providing products that lower maintenance costs, extend equipment life, and reduce stress on the environment. The bypass kidney-loop filtration technology incorporates ultra-fine micro filtration of less than 1 micron with dense cellulose membrane media that captures and entraps particulates. Resistant to cyclic flow, the filters outperform most pleated filters that often re-release trapped particles back into oil systems when there is vibration or cyclic oil flow. In addition to tightening budgets, an answer to rising economic pressure is reducing equipment maintenance and replacement costs. Improving oil cleanliness can add years to equipment life and can significantly reduce repairs. Most equipment manufacturers, plant engineers, maintenance personnel, and industry experts agree that 70-80% of hydraulic and engine-component failure is caused by contamination and moisture. Companies are experiencing increased pressure to monitor waste and document oil-disposal methods. The simple installation and easy maintenance of bypass filtration systems cover a wide range of industries and applications, and provide a way to comply and feel good at the same time. "The good news is that we reduce dependence on foreign oil and reduce waste dumped into landfills," said Jim Harris, CCECO general manager. The International Standards Organization (ISO) adopted a rating system for oil cleanliness that measures the amount of particulates in a milliliter of oil for 4μ, 6μ, and 14μ particles. Typically, new oil does not mean clean oil, and cleanliness levels range around 22/21/18 (refer to Table 1). This translates to between 20,000 and 40,000 damaging particles circulating in every milliliter of oil. That's a huge number. Bypass filtration technology can reduce this number to 16/14/12 or better. At 16, the circulating 4μ particles drop to 320-640 per milliliter. Every ISO code number reduction represents 50% fewer particulates. Many new hydraulic components (pumps, servo valves, etc.) require ISO oil cleanliness levels of 17 or less.
