介绍了包钢氧气厂引进神钢10000m~3/h空分设备所配透平膨胀机叶轮的情况,以及将其国产化变型设计的基本方法:采用整体铣制、改进流道成型、基本保证叶轮进出口几何参数不变、保持配合尺寸不变等。投运一次成功,效率比日本原机组高1~2%。
The introduction of the turbine expansion turbine impeller supplied by Shougang Oxygen Plant at 10000m ~ 3 / h air separation plant and the basic method of designing its domestic variant are introduced: the overall milling is adopted to improve the flow channel forming and the basic guarantee Impeller import and export of geometric parameters remain unchanged with the size and so on. Put into operation a success, the efficiency of Japan than the original unit 1 to 2%.
