Mounting the motor
DANGER
Inadmissible temperatures at the coupling or bearing due to misalignment of the coupling
Explosion hazard!
▷
Make sure that the coupling is correctly aligned at all times.
▷
Observe the maintenance instructions contained in the coupling manufacturer's
operating manual.
WARNING
No caution taken when lowering the motor during installation
Risk of squashing hands!
▷
Check the motor position.
▷
Adjust the speed of lowering the motor.
▷
Use suitable protective equipment.
WARNING
Components heated up for installation
Risk of burns to hands!
▷
Wear protective gloves suitable for installation work.
▷
Let components cool down after installation.
WARNING
Motor tipping over
Risk of crushing hands and feet!
▷
Suspend or support the motor to prevent it from tipping over.
The manufacturer’s product literature must be observed!
1. Thoroughly clean the shaft ends of pump and motor as well as the coupling hubs
and coat them with a layer of molybdenum disulfide.
2. Insert key 940.4 into the keyway of motor shaft 213.
3. Remove the flexible element from the coupling hub, heat up the coupling hub to
approximately 80 °C in an oil bath and slide it onto the shaft stub end.
4. Use a puller.
5. Lift the drive with suitable hoisting tackle in accordance with the manufacturer's
product literature. Lower the drive onto the motor stool.
6. After the drive has been installed on the motor stool, verify the clearance
between the two shaft ends against the general arrangement drawing. The shaft
ends must be installed flush with the corresponding coupling halves.
⇨
If the pump is not commissioned immediately, it must be preserved.
7. Check and fit the flexible elements of the coupling.
8. Align the coupling. Secure it at the key with a hexagon socket head cap screw.
9. Bolt the motor on as described in the manufacturer's product literature.
