FEASIBILITY OF WATER PUMPING AND PREPARATION STATIONS AND THE METHOD OF THEIR ENERGY-EFFICIENT OPERATION

Abstract

Aim. On the basis of a critical analysis of existing methods of solving the problems of ensuring the proper quality of water supply and post-treatment of drinking water, as well as known methods of energy-efficient use of pumping equipment, propose an original method of management with a simple schematic implementation and financial availability in terms of capital costs. Methods. Comparison of state building regulations (DBN) with the actual capabilities of centralized water mains, simple logical calculations to justify the feasibility of using drinking water pumping-preparation stations of high-rise buildings, illustrations of a typical water consumption schedule, which is proof of the need for an adjustable drive, criticism of modern methods of controlling asynchronous motors in order to formulate the principle of alternative method of their management. The results. The relevance of the creation of an electric drive system for water supply systems of multi-story buildings in the part of drinking water pumping stations has been proven, at the same time it has been established that pumping stations must have an adjustable drive to achieve rational consumption of electrical energy, and an original method of their control has been proposed. The novelty of the work consists in substantiating the main provisions and formulating further scientific tasks of research and a preliminary direction for drawing up schematic solutions of the system of integrated control of pumping pumps, which will be endowed with energy-efficient properties, provided that initial capital investments are reduced. Value. The results of the analysis are the foundation for the further development of systems of regulated asynchronous drive of drinking water pumping-preparation stations in the conditions of a high-rise multi-story building under the conditions of significant simplification of the control system, an integrated approach to energy saving and the potential opportunity to reduce capital costs.
