Overview

Experiment and simulation reveal temperature distribution influences in hydraulic valve plates, suggesting thermal management improvements.

Key Points

  • This research aims to investigate the temperature distribution and thermal characteristics of valve plates in an axial piston pump.
  • Developed a coupled heat transfer model and experimental system with 28 testing points.
  • Analyzed temperature distribution across valve plate grooves under varying load pressures.
  • Quantified the influence of pressure and rotational speed on temperature using dimensionless ratios.
  • Simulated and experimental data showed a good correlation with an average temperature error of 10.6%.
  • Identified distinct temperature gradients in valve plate grooves with high localized temperatures.
  • Noted that the effect of rotational speed on temperature is more significant than that of load pressure.
