【摘要】 为了对耐高温磁力泵进行设计和研究,保证磁力泵能够顺利启动和正常工作,对磁力泵中鼠笼转子异步磁力联轴器和泵的机械性能进行了对比分析.根据泵的基本性能公式,推导了泵的转矩与转速之间的关系.利用Ansoft Maxwell软件对鼠笼转子异步磁力联轴器进行有限元瞬态分析,得到转矩和转差率之间的关系,并分别对磁力联轴器的启动和正常工作两个阶段的磁场、扭矩进行了研究.通过将泵与磁力联轴器的性能进行综合分析,得出不同的磁力泵在不同转速下的扭矩、转差率等参数,并得出特定参数条件下泵与磁力联轴器的最优组合.试制出耐高温磁力泵样机进行试验验证,试验结果表明:在泵达到最高效率时,磁力泵的试验扭矩与理论分析得到的扭矩误差较小,说明磁力泵达到了最优化的设计结果,并验证了理论分析的正确性.更多还原

【Abstract】 In order to design and research the high temperature resistant magnetic pumps,and guarantee their successful starting and steady working,the mechanical properties of the pumps and the squirrel cage rotor asynchronous magnetic couplings were compared and analyzed.According to the basic performance characteristic of pumps,the relationship between their torque and rotation speed was gained.The finite element transient analysis was carried out for the magnetic couplings by Ansoft Maxwell software,then the variation of the torque with the slip ratio was obtained,and the magnetic field and torque situation of starting and working were analyzed.Through integrated analysis of the properties of pumps and the magnetic couplings,the torque and slip ratio of different magnetic pumps under different rotate speeds were achieved,then the best combination of pumps and magnetic couplings were obtained.A prototype of the magnetic pump was manufactured and tested,and the experimental results show that the test torque are close to the theoretical data,so the design of the magnetic pump is optimized,and the theoretical analysis is correctly confirmed by experiments.更多还原
