Fluid Care Program
The MTS Fluid Care Program protects your investment in servohydraulic test equipment by identifying the fluid contamination and deterioration that can lead to unexpected downtime and repair costs. The program combines precise fluid assessment with the added benefits of field service engineering support. The MTS Fluid Care Program is an economically sound investment that will reduce your total cost of test equipment ownership by maintaining fluid integrity.
Proactively address issues
Checks and adjustments improve system performance
Minimize risk of unplanned downtime
MTS FSE interprets results
MTS Field Service Engineer Expertise
At the outset, MTS will work with you to assess your lab and business situation. We will then design a sampling interval schedule that aligns with your equipment usage and performance goals. Your MTS field service engineer (FSE) will take the samples with a patent-pending sampling tool, review report results with you, and help you determine if and when a maintenance intervention is required.
With the MTS Fluid Care Program, you’ll receive an assessment of your hydraulic fluid that is based upon stringent standards designed to detect issues at an early stage. Your MTS field service engineer will discuss results that are out of normal range, and monitor trends over the course of time. You will also receive an annual summary of results, including fluid condition trend information and recommendations for future actions.
Parameters Designed for Servohydraulic Test Equipment
ISO CLEANLINESS TRENDS
ISO cleanliness measurement provides a summation of contaminant by size, but not by composition or mass. The MTS control limits for ISO cleanliness are specific to servohydraulic test equipment that operates at much higher pressures, and in harsher environments than typical commercial-grade hydraulic systems.
CONTAMINANT & WEAR METAL MEASUREMENT
This parameter identifies existence of contaminant by mass and composition, but not by size. The rate and stability of shedding metals is diagnostic and predictive to the health of system subcomponents, such as servovalves. This measurement provides the data necessary to intervene in a purposeful and planned manner.
ADDITIVE DEPLETION LEVELS
Additives are protectors that inhibit undesirable changes in the precision hydraulic fluid and the test machine. High-pressure, close-tolerance servovalves operating at higher frequencies can “slice” base oil and additive molecules apart during operation. When additives are depleted, your system has less protection against fluid breakdown and abrupt system failure.
WATER CONTENT PERCENTAGE
Water can cause emulsions to form and it can lead to corrosion. More than a trace of water may indicate early warning of a failing heat exchanger or ingestion of water through air breathers. The water volume measurement, when combined with the data gained from other tests, provides an indication of fluid condition.
FLUID VISCOSITY & AGE TRENDING
Viscosity is the most important property of the lubricant itself. Changes in viscosity affect the ability to form the essential lubricating film for the test machine and indicate poor fluid condition due to aging. Fluid aging is accelerated by operating at higher temperatures, presence of even trace water, fluid contaminants and additive depletions.
VARNISH / SILT / SLUDGE / OXIDATION MEASUREMENT
Operating at persistent elevated temperatures and in the presence of trace water contributes to accelerated fluid breakdown reflected in high oxidation, nitration or suspended silt particulate. MTS Fluid Analysis measures all these elements. The nitration test, which predicts varnish deposit potential, is rarely found in other fluid analysis solutions. The UC (ultracentrifuge) test detects contaminants less than 0.5 microns that can cause premature filter plugging and erratic valve operation. These tests will alert you to the potential formation of sludge, silt, lacquers, and various other hard and soft gummy surface deposits.
