7.1.3 Maintenance of the external fan
Procedure
● Check the external fan VDI 2056 annually for mechanical vibrations. The maximum
permissible vibrational severity is 2.8 mm/s measured on the end shield of the impeller-
side motor bearing.
● Regularly clean and inspect the fan. Impeller and frame are subject to natural wear
depending on the area of application and displacement medium.
WARNING
Impeller can crack
Due to deposits and the resulting imbalance there is a hazard of fatigue fracture of the
impeller. The impeller can crack in operation. Death, serious injury, or material damage
can result.
Regularly clean and inspect the fan.
● Refer to the maintenance and service information provided by the manufacturer of the
external fan.
7.1.4 Bearings
Description
The three-phase motors have grease-lubricated, rolling-contact bearings. A regreasing
device is optional.
A deep-groove ball bearing is installed at the NDE as a locating bearing. Depending on the
type of load, a deep-groove ball bearing or cylindrical-roller bearing is installed at the DE as
a floating bearing.
