Abstract: The centrifugal force,radial force and tangential stress inside hydro-cyclones were analyzed. The process of test technology for pressure field was designed. By means of dynamic pressure units with high precision,the distributions of pressure fields in the different axial positions including rotary cavity,big and small taper segments and tail sleeve were analyzed under the different operation parameters. In accordance to the results of practical test of pressure distribution,the reliability of theoretical distribution rules was verified.The study result shows that the transformation and consumption of fluid energy inside hydro-cyclone are closely related with pressure field distribution.
