摘要

摘要: 随着齿轮泵向高压大流量方向发展,间隙泄漏、粘滞摩擦、流量脉动等现象对泵工作效率的影响也更为突出。大流量齿轮泵的特点之一是模数大,齿数相对较少,使得齿高和齿厚较大,导致在高压作用下间隙泄漏损失和粘滞摩擦损失增加,尤其是粘滞摩擦损失增加幅度较大。提出了齿轮泵广义效率的概念,并建立了多个与广义效率相关的优化模型,构建了序列二次规划法的优化算法,针对高压大流量齿轮泵模数大和齿数较小的特点,用混合参数增效设计方法,优化齿轮的结构参数,解决了优化过程的全约束,克服了传统圆整法优化过程产生截断误差的难题,实现增效设计。

Abstract: Gear pump has been developed with high pressure and large flow, where the work efficiency is highly required. Clearance leakage, viscous friction and flow pulsation directly affect efficiency of pump. One of the characteristics of large flow gear pump is large module, relatively few teeth, large tooth height and tooth thickness, which result the loss increase of clearance leakage and viscous friction, especially viscous friction loss. Aiming at the characteristics of large module and few teeth of high pressure and large flow gear pumps, the concept of general efficiency of the gear pump is presented in this paper and the optimization model associated with general efficiency is established. The structure of the gear parameters is optimized by using Sequential Quadratic Programming (SQP) to solve the difficulty caused by rounding method. The Efficiency-improving design of high pressure and large flow gear pump by using hybrid parameters is realized.
