ANALYSIS OF FACTORS AFFECTING PERFORMANCE OF MECHANICAL SEAL’S END-FACE CHARACTERISTICS

Xinhuan Zou, Jun Wang, Qing Chen

ABSTRACT:Mechanical seals are widely used due to their excellent stability and low leakage rate. As for mechanical seal end-face characteristics and end-face specific pressure have crucial influence on the operating state of mechanical seal and its service life. This article analyzes the influence of spring pressure and friction characteristics on end-face specific pressure and studied the variation of friction characteristics in equipment operation through the force state of rotating ring and stationary ring.

Keywords:Mechanical seal, end-face specific pressure, spring pressure, friction characteristics
