Since reducing energy consumption is a priority for an enterprise, economic effi ciency in general is directly related to the use of pumping equipment. The demand for electricity for pumping equipment will depend on various factors: the operating modes of pumping stations and installations, the equipment used measures to reduce the cost of electricity consumed, etc. The current practice indicates extremely inefficient operation of pumping equipment. Currently, a large number of pumping stations of water supply and sanitation systems operate in an uneconomical mode. Very often, this is due to incorrect selection of pumping equipment, outdated pumping equipment, the operation of pumps in non- calculation mode. In addition, pumping equipment has been installed in many industries since the establishment of production. Such equipment is morally and technically outdated. Now,technological progress allows us to use more efficient equipment and materials that allow us to reduce energy consumption. The article presents an analysis of the energy consumption of a pumping station of technical water supply on the example of JSC «Omsk Kauchuk», a variant of modernization is proposed in order to reduce the consumption of electricity by pumping equipment. The need to modernize the pumping station of technical water supply is associated with a significant service life and high –energy consumption of pumping equipment. Two pump brands were selected and a comparative analysis was carried out. Based on calculations of energy consumption and technological characteristics, the most profitable and optimal version of the D6300-80-2b pump was chosen, since the pump performance is greater and the power consumption is less than that of the JETEX DS600-750 pump, as well as reducing the wear rate of operating elements, improving the pump’s suction capacity

Abstract Double-reservoir-and-double-pumping-station systems are commonly used for irrigation water supply in hilly regions of southern China. An optimization model for this water supply system is proposed to minimize water shortage. The model features few coupling constraints, including available water in the system and pumping volume limited by regional water rights. Dynamic programming was adopted to solve the subsystem and aggregation models. The results with the model and that with the standard operation policy were compared; the total water shortage was reduced by 87.7%, total water replenishment from outside was reduced by 2.2%, and total water spill was reduced by 60.6% for a system in Nanjing, China. The method may provide a reference for optimal operation of water supply systems comprising reservoirs and pumping stations.

The water supply of the pumping station must meet the needs of the consumer which change during the day. Therefore, its performance needs to be adjusted. Any deviation of the pump unit’s performance from the nominal value leads to additional energy costs. Under such conditions, great importance is paid to optimising the operation of electric drives of the water supply pumping station. To regulate the performance of a pumping station, it is often resorted to changing the number of operating pumping units, the engines of which are started directly from the electrical network. Medium-and high-power engines are subject to technical restrictions for a direct start, which are supplemented by the need to maintain pauses between starts. Therefore, when ensuring the desired value of pumping station performance, it is very important to consider the features of starting pump engines. Control systems are widely used in the field of electric drive and water supply. It is in these areas that the efficiency of the control system depends on the amount of electricity that will be consumed by the technological process or the reliability of its operation. It is known that pumps account for about half of all energy produced. Therefore, the issue of effective control systems is particularly relevant in the field of water supply. The purpose of this study is to increase the reliability and efficiency of the water supply system by considering the distribution properties of the pipeline network when controlling electric pump drives, which will allow coordinating the operation of the pumping station, the pipeline network, and the consumer. To achieve this purpose, the study was conducted to assess the impact of the distribution and length of the pipeline network. The system of water supply and distribution is analysed, what criteria affect the correct performance of work and what problems may arise during operation for a long period of time are investigated. Ways to optimise the operation of pumping stations to increase their energy efficiency and cost-effectiveness of installations are investigated. The main reasons for the expediency of using an adjustable electric drive to control pumping units are considered
