高压齿轮泵过渡区阻尼结构参数化

通过研究过渡区压力变化与侧板阻尼结构之间的关系,提出浮动侧板阻尼结构的参数化研究方法.以某高压齿轮泵为模型,对齿轮泵过渡区流场进行解析,并基于响应面方法建立过渡区压力变化的近似模型,在保证齿轮泵容积效率的前提下,以降低侧板过渡区突变为优化目标,对侧板高压油槽阻尼结构进行优化设计,结果表明过渡区压力突变由10.162 MPa降至3.670 MPa.

Parametric on Transition Zone Damping Structure in High-pressure Gear Pumps

To reduce the pressure mutation in transition zone of high-pressure gear pump, a parametric design method for floating lateral plate damping structure was proposed by studying the relation between the transition zone pressure variation and the damping structure of floating lateral plate. Taking the model of high-pressure external gear pump CBAk as an example, the transition zone flow field of it was analyzed. With the method of response surface methodology (RSM), an approximated pressure variation model of the transition zone of CBAk was established. With the guarantee of volume efficiency of gear pump, an optimal design to the damping structure of high-pressure tank on the floating lateral plates was put forward with an optimization goal focusing on the minimum pressure variation. Results showed that the pressure mutation of transition zone was reduced from 10.162 MPa to 3.670 MPa.
