Addon oilsupply system with air oilcooler
An orderspecific oilsupply system with air oilcooler can be used. This oilcooling system is permanently
attached to the gear unit.
Components:
•
one air oilcooler
•
one flangedon pump
•
one coarse filter
•
one pressuremonitoring device
•
one temperaturecontrol valve
•
pipework
The air oilcooler is designed to cool the gear oil by means of air from the surrounding atmosphere.
Depending on the volume flow, the oil passes through the cooler in one or more streams and through the
current of air blown in by the fan. For cold starts, a bypass pipe with a temperaturecontrol valve is provided
for.
The flow direction of the pump used is
independent of the direction of rotation
, if nothing
is specified in the documentation to the contrary.
When connecting the fittings the actual flow direction must however be observed.
A detailed view of the gear unit can be obtained from the drawings in the gearunit documentation.
When installing the gear unit with an addon air oilcooler, it must be ensured that the
air circulation is not obstructed.
The required minimum distance from adjacent components, walls, etc. is indicated in
the drawings in the unit documentation.
Depending on the application, the flangedon pump may have been replaced with a motor pump.
When operating and servicing the components of the oilsupply system, observe the operating
instructions of the components.
For technical data, refer to the data sheet and/or the list of equipment.
The cooling effect is considerably reduced if the cooler or the housing surface are dirty (see section 10,
"Maintenance and repair").
