The lubrication points (roller bearings) are located at the drive shaft between drive motor and fan impeller.
Bearings and shaft seals must be permanently supplied with the right lubricant in the amount specified by fan manufacturers.
Blowers and fans are often used in extreme operating conditions with many contaminants in the air. Dust and other substances entering the bearing system will lead to increased wear of individual components and a shorter service life of the fan.
- Contaminants (e.g. dust) in the air must not enter lubrication points
Regular lubrication of bearings and seals is essential for uninterrupted operation. Fan and blower lubrication points are often extremely dirty and hard to reach, which makes maintenance even more difficult. When manufacturer recommended lubrication intervals are not observed, the system will eventually fail as a result of lubricant starvation.
- Excessive bearing heating from insufficient lubrication
- Lubricant must meet operating requirements (vibration/ oscillation, speed, operating temperature, load)
- Observing relubrication intervals (depending on bearing type, bearing size and ambient conditions)
Advantages of automatic lubrication
- perma lubrication systems seal and protect lubrication points against contamination
- Precise metering of lubricant amount reduces lubricant consumption
- Safe and continuous lubrication in areas with explosive atmospheres
- Different lubricant volumes for precise discharge settings to meet lube-point requirements
Direct mounting on the lubrication point:
e.g. perma FLEX
- Easy, quick mounting
- For lube-points with little vibration / shocks
- For easy-to-access and safe lubrication points
Remote mounting to the lubrication point:
e.g. perma NOVA
- For lube-points with strong vibration / shocks (isolation of lubrication system)
- When workers’ safety is at risk: Mounting in safe areas
- For hard-to-access lubrication points
Blowers / Fans
Blowers and fans are used in almost all key industries where they provide adequate amounts of primary and secondary air. Flue gas fans remove air containing dust, gases and other harmful substances.
In primary air zones, induced draft fans are used in scrubbers, dust collectors, heat exchangers and desulfurization plants.
