The Thermodynamics Simulation Analysis for the Lubricant Chamber of an Axial Piston Water Hydraulic Pump

针对油水分离轴向柱塞水液压泵,建立其润滑油腔内各主要运动部件的热力学方程。根据热力学分析的基本理论,创建润滑油腔系统的热平衡方程,并用Matlab软件对其进行数值仿真。根据仿真结果得到润滑油腔内油液的平衡温度,从而分析润滑油腔内的油液粘度变化情况以及润滑油腔内摩擦副的工作状况。研究结果对油水分离水液压泵的设计以及润滑油腔内润滑油的选择具有一定的指导意义和参考价值。

In this paper, a thermodynamic equation of the major moving parts in lubricant chamber of oil-water separation axial piston water hydraulic pump is established, and a heat balance equation of the lubricant chamber system is obtained. Through numerical simulation by using Matlab, the equilibrium temperature of oil in the lubricant chamber is obtained, and the change of viscosity for the oil and the working conditions of the friction pair in the lubricant chamber is analyzed. The research of this article has a guiding significance and reference value to design the oil-water separation water hydraulic pump and the choose lubricating oil of the lubricant chamber.
