摘要
引黄入晋工程南干线一级泵站上游来水需经90°转弯进入侧向引水泵站进水池,弯道水流对进水池内水流流态影响很大。在来水角度不能改变的情况下, 通过不同运用工况试验研究, 提出在弯道右侧墙设置带缺口的导流齿,是改善弯道流态、保持进水池水面平静的有效途径。提供的最终体型及该体型下机组运行的最低限制水位, 已被设计部门采纳并实施。
Upstream incoming water of SM first stage station of the Yelloow River Diversion Project will enter the side diversion inlet pool of the pumping station through 90° bending. The bending stream will seriously influence the flow condition in the inlet pool. On condition that incoming angle cannot be changed, by means of the test study under the various operating conditions, it is undertaken that setting flow guiding tooth at the right side of the bend will be a active way through which the flow condition in the inlet pool will be improved and the water surface in the inlet pool will be kept calm. The supplied final type of build and the minimum. limited operating level of the pumping unit under the type of build have been adopted by the design department and put into effect.
