| 摘 要： | 考虑到车辆用高压叶片泵驱动转速的变化,对泵的工作腔预升压过程进行了建模,仿真出了预升压工作腔的压力、压力梯度及泵的瞬时流量随转速变化的曲线,计算了流量不均匀系数,得出了转速降低时泵性能急剧恶化的结论。

| Abstract: | When taking into account the alteration of rotational speed,the model of pre-loading process in single chamber was built.The simulation graph of pressure,pressure gradient in single chamber and discharge flow of pump vary with rotational speed were gained.The conclusion that capability of pump will be deteriorated for descent of rotational speed was obtained. |

| Keywords: | High-pressure vane pump Rotational speed Pressure gradient The uneven coefficient of flow |
