The Influence of Damping Grooves and Clearances on the Operating Parameters of a Double-Acting Vane Pump

This work contributes to the development of advanced designs of double-acting vane pumps for applications requiring high efficiency and extended service life. A comprehensive analysis is carried out using theoretical modeling, numerical simulations, and experimental validation. This study investigates the mechanical, tribological, and fluid-dynamic behavior at this contact interface. The interaction at the contact point between the vane and the stator is a critical factor affecting the performance, efficiency, and durability of double-acting vane pumps. The research focuses on contact forces, wear characteristics, and lubricant film behavior and their impact on pump efficiency and operational stability. The findings provide insights into optimizing vane material properties, stator surface finish, and lubrication strategies to enhance pump reliability. This paper aims to provide a detailed investigation of the mechanical and fluid-dynamic interactions at the vane-stator contact in a double-acting vane pump. By integrating theoretical modeling, numerical simulations, and experimental validation, the study seeks to uncover the underlying mechanisms driving the contact behavior and their impact on pump performance.
