摘要/Abstract

摘要： 通过研究扩大高压区齿轮泵主从动齿轮腔的压力分布，发现主从动齿轮腔压力分布非对称现象。以某型号高压齿轮泵为研究对象，分析齿轮轴挠度与齿轮泵径向间隙的关系。建立齿轮泵过渡区压力非线性微分方程，解析主从动齿轮腔内部流场，通过对比相应位置的压力值得出主从动齿轮腔压力分布非对称的结论。建立齿轮泵齿轮腔压力测试系统，试验数据表明对应点压力实验数值与理论值误差小于5.0%，额定工况下主从动齿轮腔过渡区压力相差4.17MPa，高压槽末端压力相差1.55 MPa。该研究为高压齿轮泵齿轮腔压力分布非对称解析及侧板倾覆力矩计算提供了理论基础。, 通过研究扩大高压区齿轮泵主从动齿轮腔的压力分布，发现主从动齿轮腔压力分布非对称现象。以某型号高压齿轮泵为研究对象，分析齿轮轴挠度与齿轮泵径向间隙的关系。建立齿轮泵过渡区压力非线性微分方程，解析主从动齿轮腔内部流场，通过对比相应位置的压力值得出主从动齿轮腔压力分布非对称的结论。建立齿轮泵齿轮腔压力测试系统，试验数据表明对应点压力实验数值与理论值误差小于5.0%，额定工况下主从动齿轮腔过渡区压力相差4.17MPa，高压槽末端压力相差1.55 MPa。该研究为高压齿轮泵齿轮腔压力分布非对称解析及侧板倾覆力矩计算提供了理论基础。

Abstract: The phenomenon of asymmetric pressure distribution in the master-slave gear cavity was found by studying the pressure distribution in gear pump master-slave gear cavity. Use one type high pressure gear pump as the research object. The relationship between the radial clearance and the deflection of gear shaft was analyzed. The nonlinear differential equation of gear pump pressure transition zone was established to analysis the internal flow field of master-slave gear cavity. To compared the pressure of master-slave gear cavity in the corresponding position, the conclusion of asymmetric pressure distribution in the master-slave gear cavity was obtained. Test data show that the corresponding point pressure experiment and theoretical error is less than 5.0%.The pressure difference is 4.17 MPa in the transition zone and the pressure difference is 1.55 MPa at the end of high pressure tank on the rated conditions.The study provided a theoretical basis for the high pressure gear pump gear cavity pressure distribution of asymmetric analysis and the end plate moment calculation., The phenomenon of asymmetric pressure distribution in the master-slave gear cavity was found by studying the pressure distribution in gear pump master-slave gear cavity.
