摘要/Abstract

摘要： 为了减小双定子单作用叶片泵必死容腔压力的突变和冲击,利用MATLAB仿真软件分析了在泵的3种工作方式下预升压的减振槽对闭死容腔压力变化的分布及影响。结果表明:配流盘上开设预升压减振槽可以有效改善闭死容腔的压力突变及冲击现象;与不计泄漏相比,计入与闭死容腔有关摩擦副的泄漏可以使闭死容腔压力的升高更加平缓,且对预升压效率影响很小;内、外泵联合工作时,闭死容腔预升压力及压力变化速率要高于其各自单独工作时的压力及变化速率,故在设计减振槽时应首先满足内、外泵单独工作时的预升压需要,再与内、外泵联合工作时的情况进行耦合优化。

Abstract: In order to reduce pressure jump and impact in sealed cavity of double-stator single-action vane pump, the influence of the pre-pressurizing groove on the distribution of the pressure variation in sealed cavity under three working conditions is investigated by MATLAB simulation. The results show that the valve plate with pre-pressurizing damping groove can effectively improve the sealed cavity pressure mutation and the shock phenomenon. Compared with excluded leakage, considering the leakage of the friction of sealed cavity allows the pressure rises more gently, and has little effect on pre-pressurizing efficiency. When the inside and outside pumps work jointly, the sealed cavity pre-pressurizing pressure and pressure variation rate exceed that when the pumps work individually. Therefore, when designing the damping groove, the pre-pressurizing requirement should be satisfied first as the two pumps work individually, then, coupling optimization of the parameters of the damping groove should be done as the two pumps work jointly.

Key words: hydraulic transmission and control, double-stator, sealed cavity, pre-pressurizing, damping groove
