Improper Use; Transport; Transport Damage - Nicotra Gebhardt RLM 53 Betriebsanleitung

BA-CFD-RLM 9.9 – 05/2021
Should any control equipment utilising electronic components be employed (e.g.
frequency inverter), the recommendations of the manufacturer are to be observed
concerning the avoidance of electromagnetic radiation (EMC) (through suitable earthing,
cable lengths, cable screening, etc.).

3.4 Improper use

An improper installation would be e.g. the transporting of :
 media with unacceptable high or low temperatures
 aggressive media.
 very dusty media.
unauthorised operation
 No operation above the indicated rpm (see type plate, data sheet)!
 No operation at rpm ranges with increased vibration (resonance)!
 No operation at rpm ranges out of permitted fan curve area (unstability of flow
pattern)!
 No operation if fan becomes polluted!
The results are: Bearings damage, corrosion damage, loss of balance, vibration,
deformation, abrasion damage.
CAUTION Prevent dynamic stress on the impeller, avoid frequent load changes!
Danger points:
There can be injury to personnel and material damage through impeller breakage,
shaft breakage, fatigue failure, fire from spark creation.

4. Transport

4.1 Transport damage

Deliveries are to be immediately checked in the presence of the carrier as being intact
and complete.
CAUTION Fans must be carefully transported!
Improper transport as e.g. unyielding, tilted positioning can lead to:
 impeller becoming jammed.
 shaft becoming deformed.
 bearing damage.
 frequency inverter becoming damaged.
4.2 Transport safety
 The transport material is to be selected according to the weight and packaging of the
fan (type plate, data sheet)
 Ensure that loading is done in accordance with the instructions
 Four-point lifting is to be provided when transporting by crane (2 slings)
