Blowers and fans are used in almost all industries.
They provide adequate amounts of primary and secondary air. Flue gas fans remove air containing dust, gases and harmful substances. In primary air zones, induced draft fans are used in scrubbers, dust collectors, heat exchangers and desulfurisation plants.
Blowers / fans are normally operated under extreme conditions. Contaminants such as dust or pumped media are raised and may infiltrate the bearing system. This causes increased wear in individual components and reduces service life.
Regular lubrication of bearings and seals is imperative. Lubrication points are often extremely dirty and hard to reach, which makes maintenance even more difficult. Specified lubrication intervals are neglected or not observed for this reason. The resulting lubrication starvation leads to increased wear and in extreme cases to failure of the blowers and fans.
Contaminants (e.g. dust) raised in the air must not enter the lubrication points
Excessive overheating of bearing points due to lubrication starvation
Lubricants must be able to withstand demands, such as vibrations and high speeds
Compliance with relubrication intervals, depending on bearing type, bearing size and ambient conditions
The lubrication points (roller bearings) are located at the drive shaft between drive motor and fan impeller.
Bearing and sealing of fan drive shaft is normally done by means of a pillow block housing or a bearing unit. These must be permanently supplied with the specified amount of the right lubricant.
Mount a perma lubrication system at the lubrication point. Depending on the conditions prevailing at the lubrication point, the perma lubrication system can either be mounted directly or remotely.
- Easy, quick mounting
- For lubrication points with little vibration / shocks
- For easy-to-reach, safe lubrication points
- For lubrication points with strong vibration / shocks (isolation of lubrication system)
- For lubrication points which are unsafe to access: Mounting in safe areas
- For hard-to-reach lubrication points
Advantages of automatic lubrication
perma lubrication systems seal lubrication points and protect against contamination
Precise metering of lubricant amount reduces lubricant consumption
Safe and reliable lubrication, also in areas with potentially explosive atmospheres
Different lubricant volumes for exact adjustment to lubrication point
