摘要

Based on the theoretic and numerical analyses, the adsorbability power of automatic cleaner was calculated and the necessary flow rate of new impeller is determined. The relation between flow rate and hydraulic losses of the pool cleaner was obtained by experiments and the necessary head of new impeller is achieved. New impeller could equip into former automatic cleaner successfully although the rotating speed is lower than before. The final test results show that new impeller's power consummation falls about 72% and the motor speed reduces about 42%. The automatic cleaner can attach itself to the wall closely and run calmly, the cost of electric system reduces sharply and the running life prolongs. Although the optimization aims come true, the outflow chamber and pipe should be optimized further.
