| 摘 要： | 对清洗机器人原有过流系统进行了分析,针对其效率低、成本高等缺点,重新设计了叶轮和出水盒.采用SIMPLE算法及标准k-ε湍流模型,把清洗机器人过流系统作为一个整体,对不同优化方案下的流场进行了数值计算.在出水盒不同位置安置挡水块进行优化的方案下,讨论了功率消耗、湍动能和效率等参数的变化.试验结果表明,新设计的流线型叶轮与新出水盒配合使用后,过流系统内部流动稳定,效率高,明显地减少了清洗机器人的功率消耗,降低了电机的转速,降低了清洗机器人的生产成本,延长了清洗机器人的寿命.

| 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. |
