- 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.
