Article Preview

A kind of hydrostatic support method was developed based on the analysis of the failure of internal gear pumps’ agglutination in this paper. The changing cycle of pressure on the internal gear was analyzed, and the grid model was built. The distribution of pressure on the inner wall of internal gear in different positions was simulated as well as the direction and magnitude by the FLUENT software. The angle range of the hydrostatic support’s channel on the inner wall of pump body was determined according to the above analysis and the force generated after making hydrostatic support’s channel was compared with the one of no hydrostatic support’s channel. The result of the numerical simulation and prototype experiment shows that the agglutination failure of inner mesh gear pumps can be avoided by hydrostatic support method.
