  • Evolution of bi-Gaussian surface parameters and Sealing performance for a gas face Seal under a low-speed condition
    Tribology International, 2018
    Co-Authors: Weifeng Huang, Xi Shi, Zhike Peng, Xiangfeng Liu, Yuming Wang
    Abstract:

    Abstract A spiral groove gas face Seal, serving as a typical non-Contacting Seal, commonly encounters face contact during a low-speed condition such as the startup, shutdown, barring and warming-up operations. By using a discrete manner, the surface-topography evolution of the two mated Sealing rings during a low-speed barring process is achieved, and is in a great agreement with the previous standard tests. The bi-Gaussian surface-topography evolution is found to well identify the end running-in, material adhesion and deep scratches. Furthermore, the surface-topography evolution exhibits a high correlation with the recorded Seal-performance indexes including leakage rate, torque and acoustic emission signal, which is helpful in exploring the deterioration mechanism of Sealing performance.

  • Design and application of non-Contacting gas lubricated Seals for slow speed services Seals for slow speed services©
    Lubrication Engineering, 1999
    Co-Authors: G. G. Pecht, J. P. Netzel
    Abstract:

    Full scale development of non-Contacting gas lubricated Seals began in the mid-1970s. This engineering effort reculted in effective Sealing of gas compressors to elinutaire unreliable and costlywet compressor Seals and associated support equipment. The concept of non-Contacting Seal technology was further re-engineered and applied to pumps for emissions control. This has also resulted in a substantial increase in equipment life or Mean Time Between Maintenance (MTBM) on difficult applications. Slow speed services found on agitators and mixers still presented an engineering problem to be solved. At slow speeds the Seal had a greater propensity to contact, resulting in wear at the Seal faces. To handle low speeds and pressures to 1E6 Pa(150 psig) an optimum set of Seal faces was developed. Performance and operating results are presented.
