Abstract To solve the problems such as low efficiency and high cost,the impeller and pumping chamber of a cleaning robot were redesigned by analyzing the flow passage components.Cleaning robots with different designs were simulated by SIMPLE method and k-ε turbulence model.The power consumption,turbulent kinetic energy,efficiency and external performance were analyzed and compared.The experimental results show that,the new streamlined impeller with optimized pumping chamber can reduce power consumption obviously,improve the inner flow and efficiency,prolong the robot′s life,and reduce the cost of manufacture.
