Implementing proper methods of filtration is the most effective way to eliminate contamination in hydraulic systems. Contamination of hydraulic and lubrication fluids, as well as lack of adequate filtration, is a leading cause of hydraulic system and component failure. To successfully maintain hydraulic systems and components, one must understand the specifics of fluid contamination, the sources for system contamination, and why filtration is the most cost-effective way to maintain fluid cleanliness.
Fluid contamination is a major contributor in approximately 70% of hydraulic system failures. Contaminant particles find their way into pumps, valves, servo-valves and various hydraulic system components where they cause wear. In extreme cases, they can cause a component to seize.
By eliminating the particles and fibers that cause wear in these systems, many of these expenses can be avoided. Filtration is the simplest means of eliminating particles.
Contamination management is crucial. Hydraulic systems rely on a clean, properly specified fluid to deliver consistent power. Every hydraulic system requires some degree of filtration to keep the fluid clean. Removing particles that harm the system, or more specifically, system components, will prevent premature wear and prolong the system’s life. By implementing a contamination management program through proper filtration and systematic maintenance, plant managers can eliminate 80% of the potential causes of premature hydraulic system failure.
