The Study on Internal Flow Characteristics of Magnetic Drive Pump

In order to study the inter flow of magnetic drive pump, the total flow field of magnetic drive pump was simulated with CFD software based on SST k-ω turbulence model, and the flow fields distribution rules of cooling channel were analyzed under different working conditions. The numerical results show that the internal flow of magnetic drive pump was disorganized under small flow condition, then the inter flow becomes gradually smooth with the increase in flux, at the same time, the area with low speed near the outlet of reflow hole and the pressure of the cool circulation channel become smaller. The pressure of cooling channel gradually decreases in flow process from deflector hole to reflow hole, and the area of low pressure is easily formed near the outlet of reflow hole.
