Corneliu CRISTESCU, Petrin DRUMEA, Constanţa CRISTESCU, Petrică KREVEY
Abstract: The paper presents some technical aspects regarding the translation mobile seals, based on the continue liquid films, used in the hydraulic driving systems, There is presented the importance of the liquid film thickness, in order to assure the seals lubrication and a minimum leakage liquid flow for a good sealing process. There is presented the mathematical modeling of the seals based on height pressure film. Finally, there are presented some graphical results obtained by the numerical simulation of the fluid sealing process and some interesting conclusions.
Key words: tribology of seals, sealing process, lubrication process, height pressure, piston rod seals.
