5.7.3
Water oilcooler
The gear unit can be fitted with a water oilcooler.
Components:
•
pump
•
water oilcooler
•
pipework
Depending on size and/or orderspecification the oilsupply system with water oilcooler may in addition
include the following components:
•
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 illustration of the gear unit and the oilsupply system with water oilcooler please 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If the gear unit is being withdrawn from service for a longer period and if there is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!
5.7.3.1 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.
5.7.3.2 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.
5.7.4
External oilsupply system
It is possible to use an oilsupply system which is separately supplied by Siemens or an external system
to ensure cooling of the oil.
Be sure to observe the operating instructions of the oilsupply system for operation and
maintenance.
5.8
Couplings, clutches
As a rule, flexible couplings or safety clutches are provided for driving the gear unit.
If rigid couplings or other in and/or output elements, which create additional radial and/or axial forces,
(e.g. gear wheels, belt pulleys, disk flywheels, hydraulic couplings) are to be used, this must be agreed by
contract.
