Wear Particle Analysis

Source

Many industrial plants feature varieties of gearboxes and hydraulic systems that are amenable to lube analysis monitoring, in addition to vibration testing. Typical ‘basic’ packages, however, don't always provide a window to fully assess machinery condition. One reason is because medium to slow speed rotating units often do not generate very small [<5microns] wear particles proportionate to large. If the large particles are not monitored, failure may occur without prior warning, if only basic lube analysis is in use. Wear particle analysis, e.g., ferrography, on the other hand, addresses these larger particles. In the case of ferrography or patch analysis, microscopic analysis is available to observe particles directly. Pictures can be taken, as well, as visual support of the Evalutor's conclusions.
