【摘要】：纯水液压传动技术因具有安全性高、压缩系数小、使用和维修成本低、节约能源等特点,在食品、制药、电子、生物工程、海洋开采等领域有着广泛的使用前景和研究价值。随着石油枯竭所带来的能源危机和人们对环境保护的日益重视,以及精密加工技术、新型材料等相关学科的发展,水压技术己成为国内外液压界的前沿课题之一。液压泵是整个液压系统的核心部分,而齿轮泵的结构和工艺简单,应用广泛。因此本文在考虑纯水特殊理化性能基础上,设计出使用寿命长、工作可靠、性能优良的水压齿轮泵有一定的理论意义和实用价值。本文在分析和总结国内外大量文献的基础上,首次将纯水液压技术应用于齿轮泵,并对其结构和性能进行了较深入、系统的研究。针对纯水齿轮泵的流量脉动高、容积效率低、径向力不平衡以及困油问题,进行了较系统地分析与研究,导出水压齿轮泵最佳轴向间隙和径向间隙表达式,为水压齿轮泵的结构设计和数字仿真模拟奠定了理论基础。考虑到纯水介质的特性理化性能,本文在油压齿轮泵结构设计基础上,提出了纯水外啮合齿轮泵的整体结构方案,并对其总体和各关键部件进行了优化设计、理论分析和仿真研究。最后分别以矿物油和纯水为工作介质对齿轮泵进行了内部流场仿真,得出水压齿轮泵的内部压力和速度分布规律,研究成果为纯水液压技术在齿轮泵上的应用,提供有益的指导和借鉴。图[27]表[7]参[67]
[Abstract]:Due to its high safety, low compression coefficient, low cost of use and maintenance and energy saving, pure water hydraulic transmission technology has a wide application prospect and research value in the fields of food, pharmacy, electronics, biological engineering, marine exploitation and so on. With the energy crisis caused by oil depletion and the increasing attention to environmental protection, as well as the development of precision processing technology, new materials and other related disciplines, hydraulic pressure technology has become one of the leading topics in hydraulic field at home and abroad. Hydraulic pump is the core of hydraulic system, and gear pump has simple structure and technology, and is widely used. Therefore, on the basis of considering the special physical and chemical properties of pure water, the design of water pressure gear pump with long service life, reliable work and excellent performance has certain theoretical significance and practical value. Based on the analysis and summary of a large number of literatures at home and abroad, the pure water hydraulic technology is applied to gear pump for the first time, and its structure and performance are studied deeply and systematically. Aiming at the problems of high flow pulsation, low volumetric efficiency, unbalanced radial force and oil trap in pure water gear pump, the optimum axial and radial clearance expressions of water pressure gear pump are derived. It lays a theoretical foundation for the structure design and digital simulation of hydraulic gear pump. Considering the physical and chemical properties of pure water medium, based on the structural design of oil pressure gear pump, the whole structure scheme of pure water external meshing gear pump is put forward, and its overall and key components are optimized. Theoretical analysis and simulation research. Finally, the internal flow field of gear pump is simulated by using mineral oil and pure water as working medium, and the internal pressure and velocity distribution of water pressure gear pump are obtained. The research result is the application of pure water hydraulic technology in gear pump. To provide useful guidance and reference. Fig [27] Table [7] Ref [67]
