MAINTENANCE
3.1.
When the dampener is new or reassembled
If the dampener is new or reassembled after maintenance it is important to retighten
the dampener housing nuts (pos. 37) after a week of operation.
Make sure to use the right torque
–

chapter
6.2.

Tightening torques

3.2.
Routine inspection
Frequent observation of the dampener operation is recommended to detect problems. For
possible issues see chapter
3.4. "Location of faults".
Leaking liquid from the dampener and changes of performance may also be detected.
We recommend to conduct a daily check and keep records of the following:
➢
Leakage of fluid from any connection of the dampener
➢
Tightness of all connection parts of the dampener
In case any of the above is not fulfilled, do not start the device and implement corrective
actions. Establish a preventive maintenance schedule based on the device service history.
Scheduled maintenance is especially important to prevent spills or leakage due to
diaphragm failure. Although dampener applications vary, a general guideline is to re-torque
the nuts every two weeks.
3.3.
Complete inspection
The intervals for a complete inspection depend upon the operation conditions of the
dampener. The characteristics of the liquid, temperature, materials used in the dampener
and running time decide how often a complete inspection is necessary.
If a problem has occurred, or if the dampener is in need of a complete inspection, refer to
chapters
3.4 "Location of faults"
and
3.5 "Disassembly of the dampener"
. You are of course
warmly welcome to consult us for further help.
Parts that are subject to wear should be kept in stock, see our recommendations in chapter
5.5.
“Stocking recommendation”
