| 摘 要： | 针对所研制的电机叶片泵样机,建立了样机性能测试系统。通过测量样机的输出流量、转速等性能参数,获得了样机的转速、效率随出口压力的变化特性。运用理论分析和数值计算对试验结果进行了分析,得出电机叶片泵样机的浸油负载和电机鼠笼转子电阻是影响样机效率的主要因素。优化鼠笼转子材料和结构,可显著提高电机叶片泵转速和效率,在最高工作压力22 MPa时,转速提高90 r/min,可达1472 r/min;效率提高2.4%,最大可达47%。对完善电机叶片泵基础理论,以及静音、高效液压电机泵的研制有重要的指导意义。

| Abstract: | An electric motor-vane pump prototype with port-plate centrifugal pump is developed, and a test system for the prototype is established to obtain the test data. Theoretical analysis and numerical calculation are used to analyze the test results. The results show that the viscosity load and the electrical resistance of the squirrel-cage rotor have a great impact on the rotational speed and further impacts on the prototype efficiency. Finally, an improved virtual prototype with improved rotor is presented to increase the rotational speed and the total efficiency. At the maximum working pressure of 22 MPa, the rotational speed of the improved virtual prototype is increased by 90 r/min and up to 1472 r/min. The total efficiency of the improved virtual prototype is raised by 2.4% and up to 47%. |
