Abstract

Increased workloads to meet the needs of a growing population have posed a number of new challenges for professionals working in the field of ecology and other sciences that study the impact of climate on the environment and buildings. The article presents the main goals for the development of pumping stations based on the development of criteria and prioritization of improving the efficiency of operation, which are formulated by the authors for the strategic, functional, morphological structure of pumped water lifting systems operating in various climatic and hydrological conditions. Research methods include the study of the ecological state of water bodies in the Aral Sea basin and their impact on the management of pumped water systems. The main criterion for research is the modernization of pumps, taking into account the operation of the main structures, their operating modes and structures. The negative consequences of the Aral Sea crisis are associated with the use of large irrigation pumping stations for decades. Some technological foundations of the management of machine water lifting systems in the aspect of safety are considered with the participation of specialists from the Institute of Ecology and Geography of the Chinese Academy of Sciences. The scientific novelty of solving a complex of complex and interrelated tasks of a methodological and technical nature is the creation of an effective regional automated system for environmental monitoring of the operating conditions of pumping stations for any region. The lack of priority work on this problem makes it impossible to optimize the modes of pumping stations at the current level of operation. Special difficulties are taken into account, in particular, the wear of pumps with an increase in the temperature of the pumped water and ambient air. The conclusions include an updated calculation of the main elements of the hydraulic unit of pumping stations in various regional conditions, the conditions for changing the water supply and the maximum use of the potential energy of surface water sources.
