摘要: [目的] 山区河流取水存在泥沙淤积等多种危及取水安全的问题,必须采用安全有效的取水装置保证电厂的安全运行。现有取水建筑物技术虽然在一定程度上减少了危害,但还是存在各种各样的问题。 [方法] 详细分析了现有取水装置中存在的一些问题,通过优化布置方式、降低泵房底板高程、闸墩与构筑物合建以及冲沙闸起吊设备直通泵房室内等措施来消除现有取水装置存在的问题。 [结果] 提出了一种新的取水装置,该装置可有效增加水泵吸水深度、优化流态、方便设备检修维护,从而进一步提高取水安全性,保证电厂安全运行。 [结论] 该新型取水装置可广泛用于山区河流引水防沙工程,带来良好的经济效益。Abstract: [Introduction] There are a lot of problems such as sediment deposition in mountainous rivers to endanger the safety of water intake. We must adopt safe and effective water extraction installations to ensure the safe operation of power plants. Although existing water abstraction technology has reduced the harm to a certain extent, various problems still exist. [Method] This article analyzed some of the problems that existing in water extraction installations, through the optimization of layout, reducing the pump floor elevation, combining the pier and structures and flushing sluice lifting equipment through the pump room indoor and other measures to eliminate the problem of existing water extraction installations. [Result] A new water extraction installations is put forward, that can effcetively increase the pump suction depth, optimize flow pattern, facilitate equipment maintenance to further improve the safety of water intake to ensure the safe operation of power plants. [Conclusion] This water extraction installations can be used in the mountainous river intake project to bring good economic benefit.
