Considerations on rehabilitation of monophilar pumping stations of the irrigation sprinkler plots

Abstract

The paper presents an analysis of the directions of rehabilitation of the single-line pumping stations from aspersion irrigation plots. The single-line pumping station consists of one or two pumping units supplied from a canal. Each pumping unit supplies a distribution pipeline equipped with irrigation hydrants. The rehabilitation and modernization has been differentiated on the structural and functional components: foundations, hydromechanical technological line, power supply system, monitoring and automation system. The case study was prepared for an irrigation plot located in the Moldavian area (Plot 7, Doniceasa Falciu, Vaslui County). The irrigation plot has 1222 ha and is equipped with 15 single-line pumping stations. The pumps type is 6 NDS and has the parameters: flow rate 241 - 345 m3 /h, pressure 6.5 - 7.5 bar and power 75 - 110 kW. The paper presents two options for the rehabilitation of the pumping stations: a - equipping with horizontal pumps; b - equipping with vertical pumps
