Centrifugal Compressors

To Mr. Norman Lieberman – In your book, Process Engineering for a Small Planet, you write about damage to a compressor because of failure of the bearing lubrication pump. The same failure occurred in our plant. How could this have been prevented?

--Oscar Harrod

 

Oscar – Are you checking that the back-up pump will start automatically? Bleed-off the pressure to the auto-start switch for the pump and see if it will start by itself and that it develops the required lube oil pressure as stated by the manufacturers.
