英文摘要 | To improve the performance of the intra-vane type pump and optimize the friction characteristics of the three friction pairs related to the vane cavity, theoretical analysis, numerical simulation, and experimental testing are used to study the mechanism of oil temperature rise in the sealed cavity of the vane pump. First, the heat generation source and heat dissipation routeways of the oil in the oil suction and oil discharge regions are analyzed, respectively. Thermodynamic modeling is conducted based on the principle of heat transfer. Then, the oil temperature rise caused by each heat generation source was simulated using the thermodynamic model. The influence of each heat generation source and heat generation route on the oil temperature rise change was analyzed and compared. Finally, a test system for oil temperature rise is designed, and the temperature changes at six positions of the experimental pump when working at three pressures are measured through experiments. Based on simulation and experimental results, the mechanism of oil temperature rise in the sealed cavity of the intra-vane type pump is analyzed and discussed. The experimental results show that the established thermodynamic model is very anastomotic to the experimental results. The experimental test value of temperature rise is greater than the calculated value. When the outlet pressure is 6 MPa, the maximum temperature rise of the theoretical calculation is 2 degrees C. Meanwhile, the maximum temperature rise of the experimental analysis is 3.5 degrees C. The maximum difference of temperature rise between theoretical calculation and experimental test is 1.5 degrees C. Therefore, the model can effectively predict the oil temperature rise in the sealed cavity of the intra-vane type pump and provide theoretical guidance for the design of similar pumps. |
