DEVICE FOR CONTROLLING WATER FLOW IN FOREBAY OF PUMPING PLANT

摘要

FIELD OF THE INVENTION The invention relates to hydraulic engineering, in particular, to devices for correcting the flow of water in the avant-chambers of various pumping stations. The purpose of the invention is to improve the reliability of the pumping station in operation by reducing the formation of vortex funnels, reverse currents, and stagnant zones in the avant-chamber. In the avancamera 1 parallel to the bottom 3 there are pipes 2 with jet-forming nozzles 8 and 9, connected by pipes 5 and 6 with a source of pressure water. The nozzles 8 and 9 are facing the pumping station and are alternately axially arranged at sharp and obtuse angles to the vertical. The jets of water coming out of the nozzles 8 prevent the formation of reverse currents and whirlpool zones, and the streams coming out of the nozzles 9 prevent the formation of stagnant zones, i.e., deposition of an anankamer. 2 Il.
