Abstract. In the national economy for the economy and efficient use of fuel and energy resources, it is important to introduce energy-saving modes of operation of livestock complexes for the rational use of electro-hydraulic tower water supply systems.
In the technical sense, the electro-hydraulic tower systems of rural water supply mainly consist of the following elements: water intake structures (more often a hole) distribution network; towers manufactured at the plant (Rozhnovsky tower) as control tanks; simplified automation system for turning on and off the deep pump depending on the water level in the tower.
Water tower - a structure in the water supply system for regulating the pressure and flow rate of water in the water supply network, creating its supply and aligning the pump schedule. Therefore, in the context of a constant increase in the deficit and prices for energy resources, more and more attention is being paid to the issues of developing an appropriate energy efficient operating mode for the submerged depths of the pumps and reducing the frequency of their switching on.
The purpose of the work is to improve the functioning of the electric hydro-hydraulic tower water supply systems in livestock complexes.
Theoretical and experimental studies on improving the functioning of electro-hydraulic tower water supply systems in livestock complexes were carried out on the basis of an analysis of the structure of the cost of electric energy for milk production, changing the operating mode of agricultural processing workshops in the livestock complex.
An analysis of energy consumption by livestock industry shows that cattle farms are the main energy consumers in livestock (they account for 46-51.5 % of the total energy consumption in the industry). The share that goes to the primary processing of milk is 4.3 %, to deeper processing, namely the manufacture of cheese another 6%, together 10.3 %. According to the research results, it is proposed to use Vespers and night hours in the electrohydraulic tower water supply systems for livestock complexes in the operating modes of the shops for processing agricultural products.
Application of regime technologies of work of agricultural processing enterprises products in livestock complexes reduces the frequency of switching on of submersible pumps by 8.3% and increases the service life of the latter by 5 – 8 %. aligns the pump schedule.
Key words: electro-hydraulic tower water supply systems, switching frequency, operating mode, cost structure
