How Fluid Contamination Causes Mechanical Failure
When contaminants enter hydraulic fluid, they can cause the system to work against itself. The same pressure and force that generate a hydraulic system’s power may cause even tiny particles to damage interior surfaces through abrasion, erosion and fatigue. This damage can cascade and create additional harmful particles. In the worst-case scenario, the result is…
How to Prevent Fluid Contamination Before It’s Too Late
Foreign particles and other substances can damage and even destroy a hydraulic system if they are allowed to contaminate the hydraulic fluid. Dirt and other particles can damage metal surfaces inside the system, causing them to weaken and fail. Water can corrode surfaces, reduce fluid viscosity and damage pumps. By the time these problems become…
Knowing When to Change Your Hydraulic Fluid Filter
Fluid contamination is the most common cause of failure in hydraulic systems, and the chances of contamination or other problems increase if you don’t have an effective plan for checking and changing your hydraulic filters.
