The State-of-the-art and Future Development of Mechanical Face Seal Intelligentization

Abstract

：The intelligentization of mechanical face seals plays an infrastructural role in the intelligentization of equipment, and also the strategical solution for the existing requirements and future innovations is developed. Based on the specific physical mechanisms and technical features of mechanical face seals, the concept of mechanical face seal intelligentization is elaborated. By the three capability aspects of perceiving, analyzing and acting, the existing techniques of the mechanical face seals and their dilemmas are reviewed. An incremental design method may have good early agility for the development of intelligent mechanical face seals; however, a systematical design method which goes beyond the traditional design patterns developed without consideration for intelligentization shall perform better in the long term. It can be expect that the intelligent mechanical face seals with deep interactivity and high autonomy will greatly boost the advancement of sealing technology and equipment intelligentization.

Tribological Behavior Characterization and Fault Detection of Mechanical Seals Based on Face Vibration Acceleration Measurements

“…In summary, the reliable and stable operation of mechanical seals is essential for the routine operation of equipment and the safe production of enterprises. However, there are technical bottlenecks in the prediction of the remaining working life of mechanical seals and the prevention of mechanical seal leakage [4]. The most common causes of seal failure include dry running, abrasives in seal fluid, sludge and bonding, thermal and mechanical distortion, coking, sleeve damage, o-ring damage, carbon ring erosion, etc.…”
