摘要
针对乐力士PGH内啮合齿轮泵在高压工况下的温升严重问题,利用SolidWorks建立了啮合齿轮泵的几何模型,并在Pumplinx与ANSYS Workbench中分别对流体热效应和机械热效应进行仿真,对分析了齿轮泵内部及外壳的温度分布及传递情况和热应力仿真分析计算。发现齿轮泵外壳在内啮合齿轮偏心圆圆心一侧温升和应力变化明显,结果表明齿轮泵温升原因主要来自齿轮泵样机与内齿圈等处的摩擦,并通过实验验证了仿真结果。
In view of the serious temperature rise of the Le Lux PGH internal gear pump under high pressure conditions,the geometric model of the gear pump was established by SolidWorks,and the fluid thermal effect and mechanical thermal effect were simulated in Pumplinx and ANSYS Workbench,respectively,and analyzed the simulation analysis and calculation of temperature distribution and transmission conditions and thermal stress inside and outside the gear pump.It is found that the temperature rise and stress change of the gear pump housing is obvious on the side of the eccentric circle center of the inner meshing gear.The results indicate that the temperature rise of the gear pump mainly comes from the friction between the gear pump prototype and the ring gear.The simulation results are verified by experiments.
