Analysis of the influence of the gap between stator and rotor on aquatarder's braking torque
In order to reveal the impact of the gap width between stator and rotor on aquatarder's braking torque,based on the independently-developed aquatarder prototype structure model,using the CFD simulation calculation method,with 0.5 mm as a segmental value,10 impeller gap width values in[0.5,5]mm were calculated and comparatively analyzed under the work condition of rotor impeller at 2 000 r/min speed.The results showed that in the gap value of[0.5,5.0]mm,at the selected 10 impeller gap values,the absolute value of braking torque calculation result was the largest when the gap was 1.5 mm,and further reached the maximum value when the gap value range was[1,2]mm.The gap between stator and rotor was not the smaller the better,and the better option range was between[1,2]mm.The study provides a reference for the optimization design and application of aquatarder prototype structure.
