Improving the efficiency of lead exploitation pumping station channels

Abstract

The paper analyzes the dynamics of channel processes in the channel of the supply channels of pumping stations. The results of field studies of the condition of the channel environment in the supply channels of the pumping stations were studied. Based on the results of field inspection and research of the supply channel, recommendations were developed to improve its operation. Analyzed and summarized the results of surveys of the hydraulic and alluvial sediment regimes in the channel of the supply channels. The results of the effects of sediment entry into the chambers of pumping stations are presented.The dynamics of reducing the capacity of the supply channels of pumping stations were analyzed;The effect of sediment on the impellers and other stationary parts of pumping units, leading to a decrease in their performance;Recommended new layout schemes of the route and sedimentation tanks of the supply channels of pumping stations;A device of additional structural elements is proposed that allows improving the operating conditions of the supply channels of pumping stations.
