Piping
10.2.8
The piping consists of the pipes and the connection elements.
Connection types:
Form-type fitting
•
Flare-type fitting
•
Welded conical fitting
•
Compression connector
•
Flange connection
•
Check the piping at least once every six months (or more frequently depend-
f
ing on operating conditions and use).
In order to allow for a visual inspection, prior cleaning may be required.
There is a test for:
Corrosion
•
Crack formation
•
Leaks
•
Indication of the application of external force
•
f
In case of leakage at fittings, you must re-tighten and record them. If there is
still leakage at this fitting, the fitting must be carefully examined for the cause
of the leakage. Depending on the findings, the seals may need to be renewed
and/or the fitting replaced with a pipe section. In case of leakage at flanges,
you must proceed in a similar manner.
In case of crack formation or leakage at welded seams, you must determine
f
and remedy the cause. Afterwards, you must replace the components con-
cerned or repair them in a professional manner.
If there are signs of an application of external force, you must determine and
f
remedy the cause. Afterwards, the component and also adjacent pressur-
ized components are to be checked for damage and assessed with respect to
further reliable use. If necessary, the component is to be replaced or repaired
in a professional manner.
If there are signs of corrosion, you must check the component for damage and
f
assess it with respect to further reliable use. If necessary, you must replace
this component repair it in a professional manner. Corrosion protection has to
be applied.
Heat exchanger (UPE5)
10.2.9
The following may be installed, depending on the drive module:
Oil-air cooler
•
Oil-water cooler
•
f
Check the cooler element for pollution of the lamellae regularly and provide for
cleaning, if necessary.
When using water filters in the cooling circuit, check the water filter elements
f
at least once every six months and clean them, if necessary.
Maintenance, repair
In case of decreasing cooling power
