Abstract
To study the pressure loss in the runner during the rotating transmission of the hydraulic joint, the local pressure loss of the hydraulic joint is simplified, and the theoretical estimation method of the pressure loss of the hydraulic joint is proposed. Based on the finite element software Comsol, the numerical analysis of the hydraulic joint is carried out to study the effect of the regularity of different fluid inlet and outlet angles and the width of the annular runner on the pressure loss of the runner. The results show that the relative numerical simulation result error of the theoretical calculation of fluid pressure loss is within 20%, and the theoretical calculation method proposed in this paper can guide the rapid evaluation of slip ring pressure loss. The pressure loss of the slip ring increases at first and then decreases gradually with the increase of the fluid inlet and outlet angle. When the angle of the fluid inlet and outlet is 30, the pressure loss of the hydraulic joint is the largest. The pressure loss of the hydraulic joint gradually decreases with the increase of the width coefficient of the runner. When the width coefficient increases to a certain value, the pressure loss reduction effect of the runner is weakened, and the optimal runner width is 0.8-1.2 times the design width of the equal section.
