Pump; Water Oil­cooler; Filter; Separate/External Oil­supply System - Siemens FLENDER B3 E Series Assembly And Operating Instructions Manual

5.10.4.1 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.
5.10.4.2 Water oil­cooler
Water oil­coolers are suitable for cooling oils. The cooling medium used is water.
For connecting dimensions, refer to the dimensioned drawing of the gear unit. The required
cooling water quantity and the max. permissible inlet temperature are given on the data sheet
and/or the list of equipment.

5.10.4.3 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 (see item 10.1).
5.10.5 Separate/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.
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.

Heating

At low temperatures it may be necessary to heat the gear oil before switching on the drive unit or even
during operation. In such cases the use of heating elements is possible. These heating elements convert
electrical energy into heat which is conducted to the surrounding oil. The heating elements are located in
protective tubes inside the housing, thus making it possible to replace them without draining off the oil.
Complete immersion of the heating elements in the oil bath must be guaranteed.
The heating elements can be controlled by a temperature monitor which emits a signal when maximum and
minimum temperatures are reached; the signal requires amplification.
