泵站前池内的流态优劣,对泵站的持久安全运行有极大的影响。经采用物理模型试验的方法,通过分析大量的实测资料,得出前池流场横向、纵向的流速分布特点,分析现象产生因素,提出合理的前池结构优化方案,以保证其间水流流态的均匀性和稳定性。
The flow pattern in the front pool of the pumping station has a great influence on the long-term safe operation of the pumping station. Through the analysis of a large number of measured data, the horizontal and vertical flow velocity distribution characteristics of the forebay flow field are obtained, and the factors that cause the phenomenon are analyzed. A reasonable optimization scheme of the forebay structure is proposed to ensure the uniform flow regime Sexual and stability.
