Spectro is now the exclusive, world wide supplier of the CSI 5200 analyzer product and services offering. Stepping Up Filtration Efficiency When oil analysis highlights an ongoing problem, it also offers an opportunity to find a solution that can reduce equipment maintenance costs and increase uptime. For example, a surface coal mining operation in Montana, USA, recently conducted oil analysis and found the service life of its production-fleet engines was being cut short by wear caused by particles that the engines' OEM full flow filtration system was not designed to remove. The fleet includes haul trucks, loaders and bulldozers. The first vehicles analyzed were Cat 992G wheel loaders equipped with 3508B engines that hold 27 gallons of SAE 15W-40 engine oil. Analysis on one 992G in the fleet indicated a particle count, by pore blockage method, of 22/21/18 with copper and iron levels at 118 ppm and 53 ppm, respectively. Analysis on the other loaders indicated similar conditions. Des-Case Corp., a manufacturer of customizable filtration solutions for industry applications—including innovative dedicated filtration systems specifically tailored for mobile equipment—recommended and provided one of its ENG-2 filtration kits for one of the mine's loaders. The ENG-2 kit, according to the company, provides filtration with depth media for a constant contamination control solution at very low ISO cleanliness levels. The system works by taking a small volume of the oil flow downstream from the OEM full flow filter and directing it through the ENG-2 system. Oil flows through the canisters at a set rate and is returned directly to the engine sump. The system is designed to prevent the canisters from being emptied when the equipment is shut down, while the small amount of oil directed through the ENG-2 system at any given time ensures the engine is never starved of oil. A pressure relief valve is also installed to prevent accidental over-pressuring of the canisters during cold cranking. The ENG-2 is a depth-type secondary filtration system. The system is designed to meter engine oil flow through the filters at 0.5 gpm. This slow flow rate, combined with the depth filtration, allows the system to have significant impact on soot and particles less than 1 micron in size. Target cleanliness levels at the time of installation were established at ISO 19/17/14 Des-Case Corp.'s engine filtration kits which, compared with the continually filter small amounts of engine engine oil cleanliness prior to oil through one or two filter canisters, installation of ISO 22/21/18, depending the system configuration. www.e-mj.com
