Hydraulic Stability Analysis of Vertical Woltmann Water Meter Impeller
In order to study the hydraulic stability of vertical woltmann water meter in operation and ensure accurate measurement and long-term stable operation of the water meter,the SST k-omega turbulence model is used to simulate the internal flow field of WSP-40 water meter based on Fluent software.The generation mechanism and variation law of radial and axial forces of impeller at different flow points are analyzed.The result shows that the rotation of impeller devi-ates from initial position due to the unbalanced force.The greater flow,the greater radial and axial forces on the impel-ler,which also affects the flow characteristics and component life of the water meter.The variation period and pulsation frequency of radial and axial forces are both related to the blade.The purpose is to provide certain reference value for im-proving the hydraulic structure of the flow passage parts of the water meters.
