【 摘 要 】

Maintaining the stable operational mode of groundwater intakes and increasing their operation period is an urgent task of urban water pipelines operating. The problem of the water supply to consumers can be solved in the process of managing the operation modes of water intakes. We consider the negative developments in the functioning of groundwater intakes. The purpose of this research is to improve the existing schemes of water supply in Pure Water Reservoir through pressure pipelines of groundwater abstraction and increase the productivity of submersible pumps. Inside the wells various pumps can be installed, characterized by the pressure and performance. Submersible pumps at nominal flow supply have maximum efficiency, so the most favorable for the pump is work to a tank of clean water. The layout of wells and common culvert is shown. Monitoring of water intakes allows setting technical parameters for selecting an independent scheme, choosing the right equipment, taking into account the joint operation of the well system - submersible pump - prefabricated water conduit - Pure Water Reservoir. Based on the results of theoretical and practical studies, a mathematical model of the energy efficiency of the system operation is proposed: a water well - Submersible Pump - collecting conduit. Reviewed the mutual influence of the operating mode of individual wells and precast culvert under various schemes of connection of pressure. Most preferred is a diagram of feed water in the basin with clean water by a separate pressure lines, in this scheme ruled out mutual influence of the operating mode of individual wells. Energy-efficient operation of the water intake with separate pressure lines must be assessed by comparing the total energy consumption in the system.
