英文摘要：

The flow field of the new type axial piston hydraulic motor pump was studied based on CFD. The models of main flow fields of the pump were built, numerical simulations were carried out and visualization results were obtained. The flow fields in the key aera of the flow channel of the pump were analyzed. Detail data of the flow fields were obtained. The velocity and pressure distri- bution in inlet channel of the pump were got. The research work is important for determining the parameters of the flow channel, opti- mizing the structure of the inner channel.
