RELIABILITY ASSESSMENT AND MEASURES FOR RESOURCE-SAVING IN WATER LIFTING ENGINE SYSTEMS IN UZBEKISTAN

The paper observes the current state of water pumping stations in Uzbekistan. More than 50% of irrigated land is provided with machine water lifting systems in the country. However, more than 50% of pumping aggregates and constructions have used up their capacities that leads to high operational expenses of energy. The authors suggest develop energy- and resource saving technologies. As they suggest the resource saving model assumes first and foremost the increase in stability and efficiency of operation of all elements of hydraulic engineering
