FOCUS ON PETROCHEMICALS

Condition monitoring specialists, WearCheck, has now extended their fuels, lubricants, air and coolants (FLAC) maintenance programme to include unique bypass filters, whichminimise contaminants, thereby extending the life of the oil and fuel. The filters were initially trialled at a chrome mine on three GHH machines running air- cooledmotors. Once proven effective, the filters were then fitted to a further 27machines in the same mine. The mine has already recorded savings of R1,7 million after paying for the implementation of theWearCheck programme. Also known as depth filters, the bypass fil- ters are bolted externally on each component, and the oil or fuel of that component passes through the filtration system, similar to how an individual dialysis machine would assist a patient to filter their own blood. The filters function best as part of a com- prehensive condition monitoring programme, and, following the successful trials, they are being widely installed on different machines. They are designed to clean oil and fuel used in a variety of industries, including mining, earthmoving, transport, construction, manu- facturing, shipping, electrical and aircraft. Fuel typically passes through three filters – first the OEM water separator, next the OEM diesel filter, and finally WearCheck’s depth filter, which is last in line, and which provides extremely fine microfiltration, screening par- ticles between 0,5 and 1 microns in diameter. The filters can either be fitted to existing components or installed during construction or rebuilding of the machine. Chris Hattingh (operations/technical sup- port for WearCheck), outlines some of the advantages of the process, “By ensuring the fuel at the injector tip in a diesel engine is super-clean, it protects the moving parts and WearCheck filters save money

keeps these within spec for much longer, al- lowing for better atomisation. “During the trial process for the filters, our FLAC programme initially identified the correct oil to be used for different components, and outlined optimum cleanliness procedures for bulk oil storage. The bypass filters were then fitted and found to extend the oil’s longevity and boosted the components’ life. “The advantage of cleaner burning fuel means more power. Because there are now potentially fewer by-products passing into the crank case oil, such as soot, the additive pack- ages don’t have to work so hard, so they may also last longer. “By using scientific data on the oil’s condi- tion, and knowing that the filters have cleaned the oil or fuel effectively, we can advise custom- ers when it is feasible to extend the oil drain interval without risk, thereby saving them money.” WearCheck celebrates 40 years of condition monitoring excellence this year.

The filters have already saved a mine over R1,5 million during an initial trial process.
