摘要 | In order to study the power capability of impeller and energy conversion mechanism of screw centrifugal pump, the adopting the methods of theoretical analysis and numerical simulation by computational fluid dynamics theory (CFD), specifically discussing the conditions of internal flow as velocity, pressure, concentration and so on. when the medium is the sand water of solid-liquid two-phase flow, and dividing the rim of the lines and wheel lines of screw centrifugal pump to segments to analyze energy conversion capabilities which along the impeller corners of it with the changes of dynamic head and hydrostatic head. The results show that the energy of fluid of the screw centrifugal pump is provided by helical segment, and the helical segment of the front of the impeller has played the role of multi-level, and when the two-phase flow internal of screw centrifugal pump do turbulent flow, the solid-liquid two-phase movement at different speeds because of the different of force field and the impeller propeller and centrifugal effect. Liquid as the main phase, so the energy conversion main is the change of liquid energy, the movement of solid-phase with the liquid coercing, the conversion of solid energy indirectly carry out by the liquid. |
