摘要
研制了具有抗泄漏、抗磨损、抗腐蚀能力的水液压内啮合齿轮泵。通过对其内部泄漏流量和运动副最佳间隙的数学建模、密封补偿机构的受力分析,完成了结构的优化设计和主要零件的设计。采用SF复合材料、9Cr18不锈钢、LC9铝合金为对偶磨擦材料,应用不锈钢表面等离子注入、铝合金表面微弧氧化的表面工艺,完成了齿轮副、密封补偿件、轴和轴承的制造。试验表明:在水介质、工作压力3.2 MPa、排量32 mL/r、转速1 500 r/m in时,其容积效率为75%、总效率为71%。结果为水液压泵的研究提供了理论依据和技术参考。
The water hydraulic internal gear pump with anti-leaking and anti-wear and anticorrosive abilities is studied. The mathematic models of the internal leakage flow and the optimum clearance between the moving-pair parts are established. The force of the seal compensation mechanism is analyzed. The structural optimum design and the main parts design are accomplished. The friction-pair materials of the SF composite and the 9Cr18 stainless steel and the LC9 aluminum-alloy are used. The surface techniques of the plasma immersion, implantation for stainless steel and the micro arc oxidation for the aluminum-alloy are applied. The gear-pair and the seal compensation and the shaft and the journal bearing are manufactured. The test of the pump indicates that the 75% of the volume efficiency and the 71% of the overall egiciency are achieved with the tap water under 3.2 MPa at 32 mL/r and 1 500 r/min. The results provide a useful theory basis and technology reference.
