摘要

叶片泵具有效率高、体积小、耐高压等特点，广泛应用于石油化工、航空航天等高科技领域。然而，传统的径向叶片泵依靠离心力来保持叶片与凸轮环的接合，这固有地限制了它们在低转速下的性能。为了解决这些限制，本研究提出了一种新的轴向叶片泵设计。基于结构和动力学分析，选择正弦曲线作为定子螺旋的参考轮廓。对关键部件进行了三维建模分析，验证了所提设计的结构合理性。制作了轴向叶片泵样机，建立了运行性能测试系统。实验结果表明，泵在不同转速下均能保持稳定的流量输出，且流量与转速之间存在明显的线性关系。磨损分析进一步表明，提高过滤系统的净化能力和保持润滑油介质的稳定性对于延长设备使用寿命和提高运行可靠性至关重要。本研究为叶片泵的结构创新和性能提升提供了一条有前途的途径，为未来的研究和工程应用提供了有价值的见解。

Research on design method of a novel axial vane pump based on structural innovation and its dynamic performance analysis

Vane pumps, characterized by high-efficiency, compact size, and high-pressure resistance, are widely utilized in petrochemical, aerospace, and other high-technology sectors. However, conventional radial vane pumps rely on centrifugal force to maintain vane-cam ring engagement, which inherently limits their performance under low rotational speeds. To address these limitations, this study proposes a novel axial vane pump design. Based on structural and dynamic analyses, a sinusoidal curve was selected as the reference profile for the stator's spiral. Three-dimensional (3D)-modeled key components were analyzed to validate the structural rationality of the proposed design. A prototype of the axial vane pump was fabricated, and an operational performance test system was established. Experimental results demonstrate that the pump maintains stable flow output across varying speeds, with a distinct linear relationship between flow rate and rotational speed. Wear analysis further reveals that enhancing the filtration system's purification capacity and maintaining lubricant medium stability are critical for extending equipment service life and improving operational reliability. This study provides a promising approach for the structural innovation and performance enhancement of vane pumps, offering valuable insights for future research and engineering applications.

期刊介绍： Vacuum is an international rapid publications journal with a focus on short communication. All papers are peer-reviewed, with the review process for short communication geared towards very fast turnaround times. The journal also published full research papers, thematic issues and selected papers from leading conferences. A report in Vacuum should represent a major advance in an area that involves a controlled environment at pressures of one atmosphere or below. The scope of the journal includes: 1. Vacuum; original developments in vacuum pumping and instrumentation, vacuum measurement, vacuum gas dynamics, gas-surface interactions, surface treatment for UHV applications and low outgassing, vacuum melting, sintering, and vacuum metrology. Technology and solutions for large-scale facilities (e.g., particle accelerators and fusion devices). New instrumentation ( e.g., detectors and electron microscopes). 2. Plasma science; advances in PVD, CVD, plasma-assisted CVD, ion sources, deposition processes and analysis. 3. Surface science; surface engineering, surface chemistry, surface analysis, crystal growth, ion-surface interactions and etching, nanometer-scale processing, surface modification. 4. Materials science; novel functional or structural materials. Metals, ceramics, and polymers. Experiments, simulations, and modelling for understanding structure-property relationships. Thin films and coatings. Nanostructures and ion implantation.
