Add­on Oil­supply System With Air Oil­cooler - Siemens FLENDER B3 E Series Assembly And Operating Instructions Manual

5.10.3 Add­on oil­supply system with air oil­cooler
For type B2.. an oil­supply system with air oil­cooler may be applied. This oil­cooling system is permanently
attached to the gear unit.
Components:
an air oil­cooler
a flanged pump
a coarse filter (double change­over filter from size 13)
a pressure­monitoring device
a temperature­control valve
pipework.
The operation is monitored by a temperature monitor in the oil sump or by a pressure
monitor.
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 gear units with add­on air oil­cooling units, 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.
Add­on pressure monitors must be connected as shown in item 5.5.2.
Depending on the application, the flanged 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 gear housing are dirty (see section 10,
"Maintenance and repair").
