Maintenance tasks for Rosenberg Fans
Type, scope, frequency, and other additional necessary activities, must be decided according to the use of the fans in the conditions predominant at the installation location. The check list below provides points of reference for the tasks to be carried out.
Measures on the fan / motor in maintenance tasks for Rosenberg Fans
At Regular As Intervals forMeasures on the fan / motor
General inspection for obvious defects
Inspect the intake area, e.g. for contamination or loose parts
Inspect equipment and its surface protection for contamination, damage, or corrosion, and correct it appropriately if required
Inspect the rotor for damage and imbalance, and carry out oscillation measurements if necessary (see below)
Ensure correct installation Inspect bearings, especially
- ease and evenness of running, lack of play
- abnormal running noises
- grease collars , loss of oil
Inspect flexible connections for leaks
Confirm the correct functioning of electrical and mechanical protective
Devices
Ensure an even gap between the rotor and the intake nozzle
Ensure that maker's plate data is legible
As Required forMeasures on the fan / motor
Confirm that the equipment is being used as intended.
When cleaning to maintain correct functioning, do not use high pressure or steam jet cleaners, or aggressive cleaning agents
Inspect screwed connections, and tighten if required, complying with the specified tightening torques
Check that connection terminals and cables or sockets are tight, and that they operate correctly; fix faults appropriately where required
- tightness of fit
- corroded parts
- damp
- visible damage
Measures while the fan is running, taking into account safety instructions in maintenance tasks for Rosenberg Fans
At Regular Intervals
· Check the fan for functioning, operational readiness, quiet running, and noise generation
· Confirm that the rotor is running in the correct direction(at all speed levels).
· Check the consumption of current with respect to phase symmetry
· Where applicable, check the functioning of vibration dampers
· Confirm the correct functioning of electrical and mechanical protective devices
As Required
Replace bearings at the end of the grease consumption period, or re-grease with approved grease.
We recommend client to do periodic preventive maintenance every 3 to 6 months during operation of the fans in
Check Lubrication for Motor
Vibration
Check the fan regularly for mechanical oscillations, and document them. Maximum vibration velocity in a radial
direction to the bearings or the bearing shield of the motor:
+ Rotors with nominal diameters >315 mm: 4.5 mm/s.
+ Rotors with nominal diameters up to 315 mm: 7.1 mm/s
