12.Push the intermediate housing with the cutout over the hoses. Screw the intermediate
housing onto the motor. Protect the hoses from mechanical stresses.
13.Screw the fan onto the intermediate housing.
14.Seal the remaining openings between the cutout and the hoses.
4.7.2
Bearingless, frame-supported rotating union
The bearingless frame-supported rotating union cannot be mounted directly on the motor. An
adapter is required for the static part of the rotating union. The adapter is not included in the
scope of delivery and must be made by the customer to match the rotating union to be used.
Please follow the following design instructions:
●
The adapter for holding the static part must be matched to the rotating union to be used.
For this purpose, the dimensions of the manufacturer of the rotating union must be
complied with. The adapter should be designed as shown in Chapter "Suggestion for an
adapter for bearingless, frame-supported rotating unions".
●
The gap between the adapter and the NDE shaft extension in the radial direction must be
as small as possible (approx. 0.25 mm) and be as long as possible in the axial direction
so that exiting coolant cannot penetrate the motor. The leakage connections must be as
large as possible and must be provided at the lowest point in the leakage chamber. The
leakage connection (G3/8") located nearest the static part of the rotating union is for
draining leakage away during operation. The second leakage connection (G1/4") is a
backup for draining away increased leakage due to faults.
NOTICE
Monitoring the backup line
To detect a fault in the rotating union in good time and to protect the motor from flooding,
it is necessary to monitor the flow rate of the backup line.
•
Make sure that a signal is output in the event of leakage.
•
Make sure that the system (coolant supply) is switched off in case of a fault.
