摘要	液压电机泵是新一代液压动力单元，相对于传统的“三段式”液压动力单元，液压电机泵具有结构紧凑、静音、无外泄漏、效率较高等突出优点，具有广阔的应用前景。液压电机叶片泵（兰州理工大学专利）将叶片泵芯插入特制电动机转子内部使得电动机和液压叶片泵合为一体，电机泵的体积大为减小；特制电机去除了电机冷却风扇，采用液压油在泵内的流动对电机泵进行冷却，设置了前置辅助泵以提高叶片泵的吸油性能，使得电机泵的噪声大为降低。本论文主要针对液压电机叶片泵的能量转换效率进行分析和研究。电机叶片泵的主要能量损耗包括电动机损耗、叶片泵损耗、沿程压力损失、油膜损耗和前置辅助泵损耗。通过理论分析、电磁场和流场数值解析，计算得出液压电机叶片泵在额定工况时的效率为63.77%，比传统液压动力单元高1.5%；并获得了辅助离心泵主要结构参数对主泵吸油性能和能量损失的影响规律。
其他摘要	The hydraulic motor pump is a new generation of hyaulic power unit.Compared with the traditional hydraulic power unit “three segment”which consists of hydraulic pump, coupling and electric motor in serial, the hydraulic motor pump have many important advantages such as very compact, very low noise, no exterior leakage and higher efficiency, so the hydraulic motor pump has many more applications. A new design which called the hydraulic motor-vane pump is put forward. The electric motor and vane pump are combined as a whole which do not need shaft coupling. The vane pump is skillfully integrated into the rotor of a special electric motor. So the volume of hydraulic motor vane pump is about 1/3 of that of traditional hydraulic power unit. The fan for cooling in the motor is ommited; oil flow is directed into channel of the motor to cool the motor pump. An auxiliary centrifugal pump is set in front of the suction port in vane pump to improve the suction performance.
