摘要 | When the axial thrust is estimated in a screw centrifugal pump under solid-liquid two-phase flow conditions by means of ordinary analytical methods, there exists problems, such as mathematic models establishment of flow and difficulties in closure of the models. Thus in order to predict the axial thrust precisely and to correlate it to the physical property parameters of the medium handled by the pump, the axial thrust in the screw centrifugal pump of type 150×100LN-32 was calculated when it transported a sand water two phase fluid by using CFD code Fluent. The two phase flow in the pump was described by the time-averaged Navier-Stokes equations in relative coordinate systems and the mixture model. The standard k-Ε two equation turbulence model and the SIMPLE algorithm were used in numerical simulations. An axial thrust was calculated after the pressure distributions in the pump were available. In this way, the problems and the difficulty aforementioned can be avoided. The relations of axial thrust to solid volume fraction, particle diameter and flow rate of the two phase flow were explored by using the computational results. The results showed that the axial thrust rises with increasing solid volume fraction, but reduces with increasing flow rate and particle diameter. The conclusion is of great significance for improving the stability of the pump and extending its lifespan. |
