PROBLEM SOLVING: POLLUTION FROM EXTERNAL SOURCES (First Part)
A customer of ours, complained about an high consumption rate of filter elements on an hydraulic plant, utilized to move glass panes. To resolve the problem, he tried to utilize filter elements less selective, with the only result to have the system more polluted and have continuous components sizings.
Analyzing an oil sample taken from this plant, we found an high concentration of a particular dust used to manipulate the panes, composed by plastic microspheres with diameter from near 10 to up to 100um. The hydraulic system utilized as reservoir breather, utilized a filtered filler plug with 40um nominal rate filtration capacity.
