城市泵站进水管口消涡措施试验研究

摘要

城市排污泵站由于用地限制，建筑物往往难以按水力条件良好的要求布置，进水管口前易产生漩涡等不良流态。本文以污水处理厂进水泵站为例，通过物模试验提出了采用纵、横向消涡梁消除进水管口漩涡的方案，并对消涡梁的布置提出了优化建议。%Due to the area restrictions of the urban pumping station ,hydraulic conditions are often difficult to meet the requirements by a good layout for its buildings ,bad flow such as vortex is observed frequently before the pipe inlet.Based on the model test of the pumping station of a sewage plant ,a program to eliminate vortex by vertical and horizontal beams was proposed ,and some suggestions on layout of vortex-eliminating beams were given in this paper.
