What is Mag Drive Pump Work?

Lets briefly discussion how mag drive pumps work
All mag drive pumps compose of two components: the outer mag assembly and the impeller

The mag-drive pump eliminates the direct drive mechanism and replaces it with a magnetic field. An outer magnetic bell housing is mounted on the end of the pump shaft. This outer bell is aligned on the outside of the rear casing. The pump impeller is connected to a smaller magnet assembly and rides on an internal shaft and bushing assembly. (The liquid end parts are all isolated within the fluid head of the pump without the need for a mechanical seal.) The smaller magnet assembly is mounted within the center of the magnetic field of the outer bell housing.
When the pump motor is started the outer bell housing begins to rotate. As the outer bell rotates, the rotating magnetic field effects the inner impeller magnet. As the two magnets begin to turn together, the impeller begins turning and displacing fluid.

让我们简单讨论下磁力驱动泵的工作原理
所有的磁力驱动泵由两部分组成:外部磁体总成和叶轮
磁力驱动泵取消了直接驱动结构，取而代之的是磁场。在泵轴的末端安装有外部磁体总成。这个外部磁体总成是安装在电机末端。泵叶轮连接到一个较小的磁铁总成上，并安装在一个内部轴和衬套总成上。(液体全部隔离在泵腔内，不需要机械密封。)较小的磁铁组件安装在外罩的磁场中心内。
当泵电机启动时，外部磁体总成开始旋转。外磁体总成开始旋转产生的磁场作用于内部叶轮小的磁铁总成上。当两个磁体一起转动时，叶轮开始转动并排出流体。
