FLENDER K.SH - Gear Unit with Oil Supply System; Measures During Commissioning

Commissioning
6.1 Measures prior to commissioning
82 Edition 06/2022 A5850-02en
You can find additional information on the required quantity of cooling water and the max-
imum permissible inlet temperature in the data sheet and the list of equipment, which are
part of the complete documentation of the gear unit.
6.1.2 Gear unit with oil supply system6.1 Measures prior to commissioning
Implement the following measures before commissioning the gear unit with oil supply sys-
tem:
• Ensure that the maximum permissible pressure in the oil supply system components is
not exceeded.
• Ensure that the maximum permissible temperature of the oil supply system components
is not exceeded.
• Using the oil supply system, lubricate the gear unit for 2 minutes using a pre-lubrication
phase. During this time, the rolling-contact bearings and gearing are supplied with suffi-
cient oil for starting.
Carefully ensure that the pre-lubrication phase is not longer than 5 minutes as the oil can
foam up at low temperatures. For oil temperatures below 10°C, heat up the oil using suit-
able measures and consult Flender in this regard.
Further information
You can find additional information on the oil cooling system in the separate data sheet, and
in the equipment list in the complete gear unit documentation.
6.2 Measures during commissioning6.2 Measures during commissioning
Take the following measures when commissioning the gear unit and document them:
• For gear units with oil supply system: Check that the oil supply system is working prop-
erly.
• Check the oil level.
• Measure the oil sump temperature (Page89) after the gear unit has run in.
• Check the tightness of the shaft seal on the gear unit (Page27).
• Check that all rotating parts are free to move.
• Check whether the shutoff valves are open.
– Check that all of the oil drain valves are closed.
– Ensure that all of the other shutoff valves are open.
• Check that the connecting pipes are firmly seated and tight.
• For gear units with bearing monitoring based on vibration measurement: Measure the vi-
bration levels of the rolling-contact bearings (Page89) to create initial and comparison
values.
• For gear units with bearing monitoring using a Pt100 resistance thermometer: Measure
the temperature at the rolling-contact bearings to create initial and comparison values.
• Bypass the pressure monitor signal for around 20seconds during commissioning. This is
necessary as the pressure in the gear unit must first stabilise.
