ЭНЕРГЕТИЧЕСКИ ОПТИМАЛЬНАЯ РАБОТА ВОДОЗАБОРНЫХ СООРУЖЕНИЙ ИЗ ПОДЗЕМНЫХ ИСТОЧНИКОВ

Abstract

Objectives Perfecting of the existing schemes of water delivery in the pure tank on a\xa0pressure piping and increase in efficiency of submersible pumps on water intaking constructions from\xa0underground sources. Discusses the negative manifestations in the operation of water intaking constructions\xa0from underground. In the mode of operation of each pump is influenced by external and internal\xa0characteristics of the system wells – submersible pump – common culvert – the clean water\xa0tank. Methods Mathematical model operation of management process of collaboration of system a\xa0water well – a prefabricated conduit with definite forms of boundary conditions. Schemes of an arrangement\xa0are shown of water wells and a prefabricated conduit. Results Interference of a duty of\xa0certain wells and a prefabricated conduit is studied, unstable work of submersible pumps is defined.\xa0The scheme of water delivery is presented to the pure tank on separate pressure pressure lines. To ensure\xa0the stability of the pumping equipment, the characteristics of the diameter of the water conduit\xa0(its hydraulic resistance) are determined depending on the total hydraulic resistance of the well\xa0equipment (well filter, pump, fittings) and the well pipeline. Monitoring of water intake structures allows\xa0you to set technical indicators for choosing an independent scheme, to choose the right equipment,\xa0taking into account the joint operation of the system borehole - submersible pump - collecting\xa0water conduit - RFI. Conclusion Energetically optimal work of water intake structures with separate\xa0pressure lines, helps to reduce water losses, while achieving significant savings in electricity. The\xa0most favorable for the submersible pump is work on the clean water tank, and not on the prefabricated\xa0conduit.
