GUIDELINES FOR REDUCING THE NOISE LEVEL OF A CENTRIFUGAL AIR COMPRESSOR INSTALLATION
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
This paper will review the best practices for installation of a centrifugal air compressor without a sound enclosure to obtain the best acoustic environment for reduced operating noise levels. An overview of the noise ...
ENSURING RELIABILITY OF COMPRESSOR GAS SEALS DURING LONG PERIODS OF PRESSURIZED HOLD
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
This paper will discuss the challenges with
contamination resulting from long periods of compressors in
standstill conditions. The reliability of gas seals is largely
dependent on having a continuous supply of clean and ...
