Hydraulic Oil Contaminants
Injection molding, heavy machinery, bending machines, lifts,
elevator equipment, construction equipment, cutting machines,
plate rollers, straddle carriers, stamping presses, mining and
quarry equipment can have serious problems associated with water
and/or particulate contamination. Water contamination in hydraulic
oil produces an emulsion, which accelerates corrosion and causes
metal deterioration. Similarly, particulate contamination can
accelerate wear on vital parts, i.e. pumps, bearings, gears,
valves, seals, etc. The presence of water and/or particulate
contamination in hydraulic oil will increase downtimes, labor
costs and disposal costs.
Solution: COMO Filtration Systems
Water and particulate contamination does not mean that the
hydraulic oil must be disposed of and replaced. Through multi-pass
filtration, the water and/or particulate can be removed from the
hydraulic oil and thus extend the fluid life. Additionally, both
fine and gross contamination can be removed through the use of
multi-pass filtration. Gross contamination (100 micron and larger
particles) is usually removed with a bag filter(s) and fine
contamination (down to one micron) is removed with our depth
filter(s).
Multi-pass filtration is performed on a kidney loop basis. In a
kidney loop, the sump/reservoir hydraulic oil is filtered
continuously, independent of the machines normal operation. Since
filtration occurs independent of the machines normal operation, a
specified or minimum flow rate does not have to be maintained.
Filtration can be performed slowly and continuously reducing total
contamination in the sump/reservoir to one micron or less.
