本文简要叙述了影响机械密封液膜反力的主要因素,从Navier-Stokes方程出发推导出液膜反力的简化公式,找出了设计机械密封的主要参数K值的合理范围,并在实践中得到了检验,可供设计时参考。
In this paper, the main factors that affect the reaction force of the liquid seal of a mechanical seal are briefly described. A simplified formula for the reaction force of the liquid membrane is deduced from the Navier-Stokes equations. The reasonable range of the K value for the design of the mechanical seal is found. In practice, Have been tested for design reference.
