Addon oilsupply system with water oilcooler
An orderspecific oilsupply system with water oilcooler can be used. This is permanently attached to the
gear unit.
Components:
•
pump
•
one water oilcooler
•
pipework
•
filter
•
monitoring equipment
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.
The required water connection must be provided by the user.
For an accurate illustration of the gear unit and the oilsupply system with water oilcooler, refer to the
drawings in the gearunit documentation.
To ensure optimum cooling performance, the specified direction of flow in the water
oilcooler must be observed. The coolingwater inlet and outlet must not be reversed.
The pressure of the cooling water must not exceed 8 bar.
If the gear unit is being withdrawn from service for a longer period and if there is
a danger of freezing, the cooling water must be drained off. Remove any remaining
water with compressed air.
Be especially careful when blowing with compressed air.
Wear protective glasses!
5.7.4.1 Pump
The pumps used are suitable for the delivery of lubricants. The flow medium must not contain abrasive
components and must not chemically affect the materials of the pump. A precondition of a proper
functioning, high reliability and long service life of the pump is in particular a clean and lubrifying delivery
medium.
5.7.4.2 Water oilcooler
Water oilcoolers are suitable for cooling oils. The cooling medium used is water.
For connection dimensions, refer to the dimensioned drawing of the gear unit. The required
coolingwater quantity and the maximum permissible inlet temperature are given on the data
sheet and/or the list of equipment.
5.7.4.3 Filter
The filter protects downstream aggregates, measuring and control devices from contamination. The filter
comprises a housing with connections and a sieve. The medium flows through the housing where the dirt
particles flowing trough the pipe are retained.
Dirty filter elements must be cleaned or replaced.
