“…Given the complexity and versatility, specific energy consumption should be used as a comparable indicator of the quality of operation and energy efficiency of pumping equipment at various and different types of pumping stations. According to preliminary calculations, the new modified impeller and straightener operation will save 560,000 kWh of electricity [19][20][21][22][23][24].…”

The research aims to develop new energy-saving modes of operation of the Karshi main canal with a cascade of pumping stations designed to irrigate the virgin lands of the Karshi steppe with water from the Amudarya River. The article discusses some calculation methods and control parametric tests of pumps by measuring the main parameters: flow, pump head, electric motor power, NPSH, and pump efficiency. Normal operation of pumping stations requires compliance with cavitation conditions of pumps of certain levels downstream. The authors have given recommendations on the use of a new floodwater design and obtained the flow's main characteristics in the section under consideration, taking into account the hydrometric characteristics. Further work continues to improve the scheme of water supply facilities by introducing new means of regulating the operation of pumping station elements into the scheme.

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.

The purpose of the research was to study the hydraulic conditions of the flow supply in the new design of the curved suction pipe and to study the effect of these conditions on the pump operation. Improving the suction pipes provides a predetermined schedule of water supply, reducing unproductive losses and the cost of electricity for water lifting. Therefore, such studies are relevant. The article uses methods of physical modeling with the introduction of the obtained data on full-scale structures. The values of the dimensionless coefficients and the corresponding hydraulic gradients for various times are studied on a suction pipe model at Qmax and Qmin, over the entire range of operating parameters. The chosen method of improving the suction pipes provides an optimal water supply schedule, reducing unproductive losses and electricity costs for water lifting. During the reconstruction of pumping stations, projects for the modernization of water supply facilities were introduced with annual energy efficiency amounting to 1312 million sum for the pumping stations Kuyumazor, Kiziltepa-1 - 105 million sum.
