摘要

为了初步探索径向安装偏差对大型水轮机内部流动的影响，我们以一台高质量的1000mw混流式水轮机组为研究对象，探索当径向安装偏差偏离稳定流动的螺壳方向0.5 mm时，会发生什么样的情况。我们发现，首先，间隙小的地方的压力要高于其他地方。其次，在流动部位中，不同部位受到不同程度的影响。无论是压力还是速度，冠腔受到的影响最为严重，而底环腔几乎没有影响。

Influence of Radial Installation Deviation on the Flow Characteristics of a High-Quality 1000 MW Francis Turbine

In order to preliminarily explore the influence of radial installation deviation on the internal flow of large turbine, we take a high-quality 1000 MW Francis turbine unit as the research object to explore what kind of situation will occur when there is a radial installation deviation of 0.5 mm away from the spiral case direction of the steady flow. We found that, firstly, the pressure in the place with small clearance is higher than that in other places. Secondly, in the parts of the flow, different parts are affected to different degrees. Whether it is pressure or speed, the crown chamber is affected most seriously, while the bottom ring chamber has almost no influence.
