Damper System Operation 46 Routine Maintenance
As a guideline, for a test system that operates eight hours per day, one week will
equal 40 hours, and one month will equal 160 hours. For a test system that
operates up to 24 hours per day, one week will equal 160 hours and one month
will equal 720 hours.
When to perform
visual checks
Routine maintenance procedures that are scheduled on a daily or weekly basis
usually involve visual checks only, and should not interfere with the operation of
your test system. These checks will help you assess which procedures must be
performed before running the next test. For example, the dirty filter indicator on
the HPU signals that it is time to clean or change the filter.
You can perform these visual checks at the start of each day and incorporate them
into your preparations to run a test.
Note It is highly unlikely (unless you are running an extremely long durability
type of test) that you should need to stop a test simply to perform a
routine maintenance procedure.
Changing the intervals
You can change the time interval for performing maintenance checks, based on
the operating conditions for your system. Operating conditions that affect the
maintenance schedule include air quality, temperature, humidity, how often you
run tests, and whether you use a pump room or a hydraulic power unit to supply
hydraulic fluid to the system. Keep a log to observe trends in your system, then
adjust your maintenance schedule as needed. For example, you might find that
you do not have to perform daily checks of the hydraulic fluid, and decide to
check it once a week instead.
Additional
maintenance
Because of the variations in system configurations, the maintenance schedule
table lists the typical procedures for the associated products. Additional
maintenance procedures might be required depending on the specific product
model. Refer to the product manuals for complete maintenance information.
Additional maintenance procedures can be required whenever you notice
decreased system performance. An example of this type of maintenance is
servovalve filter replacement. Many of these procedures require additional
training and should be performed by MTS service personnel.
Information about analyzing hydraulic fluid is contained in the MTS Fluid Care
Guide that accompanies each hydraulic power unit, and in the appendices of
maintenance manuals
