切削叶轮调节IEJ型离心泵的性能

Performance of IEJ Cutting Impeller Centrifugal Pump

通过切削叶轮缩小叶轮直径,改变离心泵实际性能,降低噪音和电机电流达到稳定长周期运转的目的。介绍了IEJ型离心泵的具体计算方法、切削量选择及使用效果。

The diameter of the impeller is reduced through cutting impeller to improve the factual performance, reduce noise and motor current, so that it can be run steadily for a long duration. Calculation method of IEJ centrifugal pump, selection of cutting amount and service results are introduced.
