Test and Analysis of Aeration Performance of Permanent Magnet Impeller Aerator

In order to explore the application effect of permanent magnet motors on impeller aerators and understand the aeration performance of impeller aerators equipped with permanent magnet motors, according to the test procedure of "SC/T 6009-1999 Test Method for Aeration Ability of Aerators". The standard pool of the aerator is used as the test platform. The traditional impeller aerator of the three-phase asynchronous motor type and the permanent magnet impeller aerator of the permanent magnet motor are tested and compared, and the effect of the aeration effect of the impeller aerator is affected. Factors such as the diameter of the impeller and the idling speed of the impeller are investigated. The research results show that the overall aeration performance of the impeller aerator with a permanent magnet motor is comparable to that of the traditional impeller aerator,the level of aeration capacity is equivalent, and the power efficiency is higher than that of the traditional impeller aerator. Under the same level of aeration capacity, the input power of the permanent magnet impeller aerator is relatively low, and the power efficiency is high. For the same aerator, the larger the impeller diameter and the higher the idling speed, the higher the aeration capacity and the relatively lower power efficiency.
