结合广昌泵站前池水流流态进行了模型试验研究。针对原设计方案前池水流出现异常现象,如出现旋涡、噪声和振动等现象提出了在供水管出口设置八字形导流隔板、在水泵和后墙之间加隔板的修改方案。修改后的方案在各种工况下前池水流均匀,无旋涡产生,机组运行平稳,从而提高了泵站效率和保持安全经济运行,改善了运行人员的工作环境。 Combined with the flow pattern in the forebay of Guangchang Pump Station, a model test was conducted. In view of the phenomenon of the anomalous flow in the front pool of the original design scheme, such as vortex, noise and vibration, a modified version of the figure-shaped diversion diaphragm at the outlet of the water supply pipe and the partition between the water pump and the rear wall is proposed. The revised scheme in all conditions before the pool flow uniform, no vortex, the unit running smoothly, thereby enhancing the pumping station efficiency and maintain safe and economical operation, improve the working environment of the staff.
