HEAVY EQUIPMENT REQUIRE CONTAMINATION-FREE FLUIDS

摘要

Are you using 1950s maintenance practices on your 21~(st) Century heavy equipment? If so, you are probably doing more damage than you think. Modern heavy equipment are high performance thoroughbreds. They may appear to be tough brutes that appear impervious to dust and dirt, but if even a bit of invisible dust gets into the equipment's fluids, you will be experiencing reduced performance, higher maintenance costs, and shorter lives. In order to shoehorn the high performance into smaller packages, heavy equipment engineers have been forced to maximize several systems like hydraulics and the fuel system. This requires higher pressures like 6,000 psi in hydraulics and 40,000 psi in fuel systems. These, in turn, require tighter tolerances, which means smaller particles of dirt and dust, which didn't bother equipment before, now can cause considerable problems. In fact, a 5 micron particle can damage modern heavy equipment (a human hair is 80 microns in diameter).
