Study on the Field Dynamics of the Seal Cavity Flow Field for High Parameters Bellows Mechanical Seal

Abstract

Based on the computational fluid dynamics (CFD) theory and numerical simulation methods, the seal cavity flow field for the bellows mechanical seal under such the high temperature, high pressure, high-speed as complex working conditions was numerically simulated, and the temperature field, velocity field, pressure field, turbulent kinetic energy and the flow field vorticity distribution of the medium of the seal cavity were obtained, the three-dimensional fluid flow in the seal cavity, the heat transfer characteristics and the impact on the sealing performance were analyzed in this researching.

Analysis of Flow Field Dynamic Characteristics of Friction Pair Fluid-Film for Heat Pump Mechanical Seal

“…Heat pump mechanical seal system is a kind of mechanical seal type that was commonly used in the petroleum and chemical industry; it is also an important studying object for mechanical seals with the high parameters (high temperature, high pressure and high speed)and the extremely working condition [1]. When the heat pump mechanical seal operates, the pressure that the fluid-film formed is non-linear.…”
