FAILURE OF THE METHODOLOGY
Parameters
Hydraulic systems mostly (85%) fail due to contamination problems, and the lubricant requires premature changes due to contamination. For this reason, ISO 4406 parameters have been defined for hydraulic system components.
Clean Start
Lubricants from new mostly fail ISO cleanliness and should enter the equipment with a code no higher than 16/14/12, but to achieve this goal you have to deal with low temperatures (viscosity) when filtering new oil.
Monitoring
Monitoring practices are often NOT the most effective because sampling methodologies can alter results and furthermore do not have predictive solutions to mitigate results outside the optimal ISO parameters indicated by the OEMs.
Staying Clean
Dialysis has proven to be ineffective because the filtration systems are not correctly sized or the equipment is out of parameters in a short time without effective monitoring to determine the necessary interval for each dialysis.
THE FMS
PROPOSAL
EVALUATION
An expert advice that allows users to know their current condition and the engineering applied to their needs to maintain an operation within ISO 4406 standard according to OEMs stipulations.
Monitoring
Using certified equipment, the new lubricant is audited and the results of contamination control practices are confirmed in real time and online for the user to validate the success of the FMS approach.
Execution
A pilot demonstrates to the customer the technical and economical feasibility of maintaining hydraulic systems within optimal ISO parameters with water and emulsion control based on the individual needs of each operation.
HYDRAULIC BYPASS
Modern hydraulic systems impose demanding cleanliness conditions to preserve and extend the service life of such sensitive components as servo valves, vane and piston motors/pumps, and directional and pressure control valves.
The contamination cycle of abrasion, surface fatigue, and accumulating debris continues until the particles are either caught by a filter or flushed from the system. The longer the particles stay in the system, the more damage they cause.
