Thermodynamic Modeling and Analysis of Asymmetric Axial Piston Pump
In order to accurately analyze the temperature distribution of various components of an asymmetric axial piston pump,considering the spin of the slipper,a mathematical model for the viscous friction power loss and volumetric power loss of the friction pair of the asymmetric axial piston pump was established.Fluent software was used to simulate and calculate the heating situation of the pis-ton pump,and the effects of the piston pump speed and working pressure on the heating situation of the piston pump were discussed.The results show that the highest temperature of the asymmetric piston pump occurs at the slipper,and both the speed and working pressure can affect the heating situation of the piston pump,the effect of speed is more significant.When the spindle speed increases from 1 000 r/min to 2 000 r/min,the maximum power loss increases by 269％,and the maximum temperature rise is 12 ℃.
