With cavitation model being considered, a LP (Lumped Parameter) model and a CFD (Computational Fluid Dynamics) model on the flow and pressure characteristics of the axial piston pump for seawater desalination were created. Based on the geometry structure and operating condition of the pump, these two models were numerically calculated and corresponding results were compared and discussed. Both the two models can describe the dynamic flow and pressure characteristics of the pump. The CFD model is accurate and many details such as cavitation position can be predicted. LP model is a simplified model compared with CFD model. Because the damping effect of the inlet of the pump is neglected, this model is only suitable for rough calculation in engineering.

Axial Piston

In order to realize that an asymmetric flow piston pump can control an asymmetric differential cylinder, a proposal about the application of an asymmetric flow-distributing axial piston pump is put forward. The new type of piston pump can output the flows with two different values to control the movement of the differential cylinder directly in the closed circuit and realize much ideal result of the control of the differential cylinder by a single pump. Also a simulation model of the hydraulic pump is established under the circumstance of SimulationX software, considering the characteristics of the movement of an individual piston, the oil compressibility, and the flow distribution area changed with the rotation angle. The key data of the pump is defined by means of digital simulation. In particular, an analysis is made on the dimension of the unloading groove of the port plate and the characteristics of the flow pulse of the pump. Furthermore, an experimental model pump is manufactured, the basic performances of the pump is tested on the experimental platform at various rotatory speeds such as pressure, flow and noise, in the end the accuracy of the principle is verified.
