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
