When repacking the bearings of a liquid ring compressor, what is the recommended amount of grease to fill the housing?

In the repacking of bearings in a liquid ring compressor, the recommended amount of grease to fill the housing is typically between 1/4 to 1/3 full. This level is optimal because it allows for adequate lubrication while preventing overpacking, which can lead to excessive heat generation and the potential for bearing failure.

Filling the housing to this specified level ensures that the grease can effectively circulate during operation, providing sufficient lubrication for the moving parts without compromising the efficiency of the compressor. Overfilling can trap air and create pockets, which may affect the balance and performance of the compressor. It may also lead to higher temperatures and premature wear.

Using a correct fill level is crucial in avoiding issues associated with both under-lubrication and over-lubrication, ultimately maximizing the lifespan and reliability of the compressor bearings.
