Abstract

The textured valve plate pair's tribological performance directly determines axial piston pumps' efficiency and lifespan. The tribological parameters are significantly impacted by the running-in process. In this paper, ring-on-block testing with three types of textures was conducted to analyze the friction coefficients, running-in time, wear rates, and micrographs under two running-in conditions. In addition, the specific textures were applied during the pump's running-in tests. Results show that the lowest friction coefficient and wear rate of textured specimens are reduced by approximately 29.11 % and 74.88 %, respectively, compared to untextured specimens. The wear mechanism of the textured valve plate pair is primarily abrasive wear. Higher pressure and speed are beneficial in reducing friction and wear during the running-in process.

轴向柱塞泵带表面纹理阀板的磨合摩擦学性能和机理研究

纹理阀板对的摩擦学性能直接决定了轴向柱塞泵的效率和使用寿命。摩擦学参数受磨合过程的影响很大。本文采用三种纹理对阀板进行了环形测试，分析了两种磨合条件下的摩擦系数、磨合时间、磨损率和显微照片。此外，还在泵的磨合试验中使用了特定的纹理。结果表明，与未纹理试样相比，纹理试样的最低摩擦系数和磨损率分别降低了约 29.11 % 和 74.88 %。纹理阀板对的磨损机理主要是磨料磨损。在磨合过程中，较高的压力和速度有利于减少摩擦和磨损。

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
