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.INDEX TERMS Flow characteristics, inter flow, magnetic drive pump, numerical simulation.

“…Shoda [1] analyzed the nonlinear characteristics of the gear coupling through the method of gear tooth contact analysis and experimental verification and found that the load and misalignment would lead to the change of the contact area of the gear coupling and thus generate the nonlinear damping and stiffness. Hao Chang [2,3], Yang yi [4], Calistrat [5] studied the misalignment and high-speed transmission characteristics of the gear coupling and showed that the sliding friction and additional bending moment between the tooth surfaces were the main causes of selfexcited vibration and wear of the equipment shaft system due to the misalignment between the internal and external gears of the gear coupling.…”

In order to study the effect of geometrical parameters of magnetic drive coupling on magnetic torque and magnetic eddy current loss, based on the basic theory of electromagnetic field, the influence factors of magnetic performance of combined push-pull magnetic drive coupling are analyzed and optimized by means of finite element numerical calculation and orthogonal experiment. The optimal geometrical parameter scheme of magnetic drive coupling was obtained, and the magnetic performance of the optimal geometrical parameter model was studied experimentally. The geometrical parameters of the optimal scheme of magnetic drive coupling are internal radius of magnet r = 80 mm, thickness of permanent magnet tm = 8 mm, axial length Lb = 144 mm, and thickness of yoke iron ti = 10 mm. The research shows that the optimization design method proposed in this paper is reliable in the design of magnetic drive coupling and can provide some theoretical reference for the design of magnetic drive coupling and the optimization of magnetic torque and magnetic eddy current loss.
