Pressure analysis of a new type of axial piston pump's port plate pair with uniform flow

摘要

A new type of axial piston pump with uniform flow and balance hydraulic pressure was detailed in this paper. Port plate pair's pressure of the pump was analyzed with calculation formula, and numerical analysis of port plate pair's pressure was carried out by using finite difference method with the help of Matlab. The results showed that this new type of axial piston pump had balance hydraulic pressure, no overturning moment, and fit hydraulic oil film stiffness.
