Type of article: Article

Summary

MANY LARGE CENTRIFUGAL COMPRESSORS IN HYDROCARBON OR SIMILAR PROCESS PLANTS HAVE LIQUID FILM SHAFTSEALS, THE SEALING FLUID GENERALLY BEING OIL. SUCH SEALS ARE DESIGNED WITH A SMALL OIL FLOW BETWEEN THE SEALING SURFACES. APART FROM CASES WHERE OIL CONTAMINATION IN THE COMPRESSED GAS IS NOT PERMISSABLE, THE DESIGN REQUIRES AN EXTENSIVEOIL SUPPLY AND FILTERING SYSTEM. DRY SEALS, IE SEALS WHERE THE FACES ARE SEPARATED BY A GAS FILM, ARE CHEAPER TO INSTAL AND OPERATE, AND HAVE GIVEN MORE FAULT FREE RUNNING. THE DESIGN PRINCIPLES OF DRY SEALS ARE DISCUSSED AND ILLUSTRATEDWITH SOME RECOMMENDATIONS FOR RETROFITTING. D.W.H.
