Evaluation Of Liquid Film Seals, Associated Systems And Process Considerations
Abstract
Buffered bushing liquid-film seals have been in existence for some time and have proven to be quite reliable for most centrifugal compressor applications. However, industry has been demanding more from seals and their associated systems over the years. While expecting better performance in terms of lower inner sealant leakage, which means tighter clearances or lower differential pressures, or both, industry primarily wants reliability. Therefore, manufacturers were forced into alternate seals, among which is the pumping type liquid-firm seal. This paper will deal with one company’s approach to meet industry’s many seal requirements with a pumping type liquid seal. Pertinent process considerations will be brought out which establish the proper seal variation as well as the proper associated system for best operation.
