abstract = "The particles contained in the fluid can cause erosion wear, which is one of the main causes of complex electro-hydraulic system failures. The structure of slide valve pairs is a common form in hydraulic systems, and the geometric accuracy of their sharp edges has a significant impact on the performance of hydraulic servo systems. The high-speed two-phase flow between narrow gaps makes the sharp edges of the slide valve prone to wear, ultimately leading to system performance degradation. In this paper, the Euler-Lagrange method is used to study the two-phase flow characteristics and erosion characteristics in the spool pair under different working conditions. The erosion rate distribution in the severely eroded area of the spool pair was obtained, and the evolution trend of the sharp edge contour was predicted. The results indicate that there are significant differences in the erosion characteristics of the sharp edges of the spool pair under different operating conditions due to the influence of fluid velocity and direction. This article provides a reference for further research on the anti-erosion wear performance and life prediction of spool pair.",
