□
Is all pipework cleaned and installed in accordance with the assembly instructions?
NOTICE
Property damage
Damage to the gear unit is possible.
Particular care must be taken to ensure that the oil conducting pipework is clean, since any dirt in it
would be conducted through the gear unit before it could be filtered out at the filter of the oil-supply
system.
□
Are the coupling and the motor correctly aligned?
□
Have the pipework and the hoses been correctly fitted?
□
Have the pipe and hose connections been checked for leaks? Particular attention must be given to the
flange connections on the suction line. If air gets into it, the oil tends to foam.
□
Is the oil in the oil reservoir (tank of oil-supply system and/or gear unit) low-foaming on the surface
during operation? If there is foam, check all the suction line connections. If necessary, also contact the
oil manufacturer.
□
Is the tank of the oil-supply system and/or the gear unit and the tilting pad thrust bearing chamber been
filled with oil? The oil level must be checked while the oil-supply system is running and the gear unit is
in standstill.
□
Is the oil level between the MIN and MAX marks on the oil level indicators?
□
Has all the monitoring equipment been connected up in accordance with the terminal diagram?
□
Has the electric interlock between the gear unit, oil supply and mill drive motor been checked?
Document the following of the checks:
□
Function of the interlock according to interlock specifications.
□
Adjustment and function of flow monitor or flow transmitter, pressure switch or pressure transmitter,
and temperature sensor.
□
Cooling-water supply opened, on oil-supply systems with water oil-cooler.
□
Sufficient air supply on the vents if the oil-supply system has an air cooler.
□
Has the alignment of the gear unit and adjacent components been checked, logged and documented?
□
Evenness of the foundation.
For further checks, see the operating instructions for the coupling, motor, oil-supply system and vertical
mill.
Note
The report must be kept with these instructions.
