Analysis and Optimization on Micro Labyrinth Screw Pump
Based on the requirements of the spacecraft thermal control system for the small flow and high head of the micro labyrinth spiral pump,the optimization design of the structure parameters of the miniature labyrinth spiral pump was carried out.The spiral lift Angle,the number of threads and the dynamic interface angle of the flow channel were taken as the research objects,and the head was taken as the optimization objective.The response surface analysis and multi-parameter optimization were carried out by combining numerical calculation and experiment.The optimal structural parameter combination is obtained,and the effectiveness of the optimization results is verified by experiments.The maximum head of the optimized micro labyrinth spiral pump is increased by 65.4％.The analysis provides technical support for the performance improvement of the micro labyrinth spiral pump.
