摘要:
电机泵温升情况是影响其性能的关键。为了研究电机泵的温度分布规律,以及影响其散热性能的因素。本文以轴向柱塞式电机泵为例,根据共轭传热原理建立其三维温度场计算模型,运用有限元分析方法,仿真得到其稳定运行时的温度分布状态。结果表明,额定工况下电机泵定子区域温度最高为70.47℃,转子区域温度最高为59.6℃,高温主要集中在定子绕组区域。在此基础上,对电液泵流道结构以及定子通油孔对其温升的影响进行了分析。减小单个流道宽度以增加流道周向数量能有效增强电机泵散热性能;且当流道宽度与流道高度相等时,电机泵散热性能最差;而定子铁芯打通油孔后,电机泵定子温度比打孔前下降了4.13℃,转子温度无明显变化。
Abstract:
In order to study the impact of motor pump temperature and cooling flow structure on the temperature rise,in this paper the axial piston motor pump was taken as the research object.On the basis of Newton′s law of cooling,the theoretical formula on the impact on the temperature rise of the motor pump flow channel structure was established.A simulation model of the three-dimensional temperature field simulation of motor pump temperature distribution and temperature rising under different flow channel structure was established.The theoretical derivation was consistent with the finite element simulation results.The rated working conditions,the stator region of the motor pump had the highest temperature,and the high temperature was mainly concentrated in the stator winding region,while the rotor region had a lower temperature.Reducing the width of a single channel to increase the circumferential number of channels could effectively enhance the heat dissipation performance of the motor pump.When the width of the channel was equal to the height of the channel,the heat dissipation performance of the motor pump was the worst.The stator temperature of motor pump decreased obviously compared with that before drilling,and the rotor temperature had no obvious change after the stator core was set with oil hole.The research results provided a theoretical basis for the design and optimization of the motor pump flow channel structure.
