Ensure that the motor manufacturer's maintenance specifications as well as
information provided by the manufacturer for the switches and control units as
well as the frequency inverter are observed.
In order to assure a safe operation we recommend to make checks of the fans in regular
intervals by specialised service personnel or by a specialised company and to document
the result of these checks.
The type, magnitude, and interval period as well as all works which may be necessary in
addition depend on the use and the surrounding conditions of the fan and have to be
determined case by case.
The recommendations for checks and maintenance acc. to VDMA 24186-1 may be
found at the internet site: www.nicotra-gebhardt.com.
CAUTION No high pressure cleaners (steam rod cleaners) are to be used!
7.2.1 Vibrations
The fan has be checked regularly whether vibrations may occur. The maximum vibration
speed in radial direction must not exceed 4.5 mm/s to monitored at the bearing or bearing
housing of the fan or motor. For fans of a impeller diameter up to 315 mm a vibration speed
of up to 7.1 mm/s is acceptable. When exceeding the permitted vibration values, it is
mandatory to rebalance the entire rotating unit in accordance with DIN ISO 1940-1.
7.2.2 Dismantling of the impeller
After dismantling and reinstalling an impeller, the fan must be checked for mechanical
vibrations. It may be necessary to rebalance.
7.3 Inlet and discharge connections
Flexible sleeving (compensators) between the fan and plant parts are to be checked at
regular intervals.
CAUTION Unsealed sleeving leads to breakdowns and danger from escaping transported
medium and must be replaced.
