  • Tandem Dry Gas Seals Design and Maintenance Considerations for Enhanced Reliability and Performance
    Day 2 Tue November 12 2019, 2019
    Co-Authors: Girish Kamal
    Abstract:

    Abstract Dry Gas Seals (DGS) for centrifugal compressors exist in the process industry for the last almost thirty years and almost all the compressor units operating in the industry today are equipped with Dry Gas Seals. High operating and maintenance costs, unreliability and hazardous characteristics inherent with the conventional lubricated Shaft Sealing Systems have resulted in widespread utilization of the DGS and their associated Sealing Systems. This paper shall cover the design considerations including best operation and maintenance practices to enhance dry gas seals operating life and performance including: ▪Major factors affecting Dry Gas seals service life▪Seal Gas supply and control requirements▪Primary Gas seal venting and health monitoring▪Secondary Gas seal venting and health monitoring▪Separation Gas supply control Systems and health monitoring▪Recommended Alarm, Shutdown and Start-Permissive conditions

  • TANDEM DRY GAS SEALS – Design and Maintenance Considerations for Enhanced Reliability and Performance
    Turbomachinery Laboratory Texas A&M Engineering Experiment Station, 2018
    Co-Authors: Kamal Girish
    Abstract:

    Technical BriefsDry Gas Seals have been in existence in the process centrifugal compressor industry for the last three decades and majority of the compressor units in operation today are installed with Dry Gas Seals. DGS Sealing and the associated Systems gained importance predominantly due to unreliability, high operating and maintenance costs and hazardous characteristics inherent with the conventional lubricated Shaft Sealing Systems. This Technical Brief shall cover the best practices to improve dry gas seals reliability and performance including: ? Design and Maintenance considerations ? Major factors affecting Dry Gas seals life and efficient operation ? Seal Gas supply and control requirements ? Primary Gas seal venting and health monitoring ? Secondary Gas seal venting and health monitoring ? Separation gas supply and control requirements ? Recommended Alarm and Shutdown condition

  • Defect Analysis and Elimination Measures of Shaft Sealing System of 600MW Steam Turbine
    Electrical Equipment, 2006
    Co-Authors: Wei Xifeng
    Abstract:

    Defects existed on the Shaft Sealing Systems of No.1 and No.2 steam turbines in Pingwei Power Plant,such as:large outward leakages of and steam Sealings of high and inter mediate pressure cylinders,high temperature of Shaft Sealings,large vibration of bearings,too high water contents of main oil tanks,oil tanks of small steam turbines and Sealing oil etc.The article analyzes the main canses for the defects existing in the Shaft Sealing system,briefs the redesign and retrofit situation of Shaft Sealing system in the uprating retrofit of No.2 steam turbinegenerator and also briefs the experiences with the successful handling of defects.
