Abstract
The article considers the electromechanical water supply system of a residential building, the pumping station of which includes two half-power capacity centrifugal pumps connected in parallel. At the same time one pump is adjustable and provides stabilization of pressure in a hydraulic network at the necessary level, the second - not regulated which is switched on at the maximum loads and uses soft start system. For more accurately assess the dynamic and static characteristics of water supply, the features of the daily schedule of water yearly consumption, defined in spring, autumn, winter and summer periods are considered. Using the SimHydraulics library of the MatLab application package, a refining model of the hydraulic network has been developed, which allows to take into account the characteristics of network and design features of its individual elements with a high degree of accuracy. The study of the level of accuracy of pressure stabilization of the water supply system is performed, as well as the results of the analysis of energy characteristics of the electromechanical water supply system with variation of its load level during the day and year. Based on the review of the previous research, the expediency of using cascade pumping unit electromechanical systems for water supply systems of residential buildings was determined. Recommendations for the use of a refining model of the hydro network in the study of the modes of operation of the water supply complex are presented.
