Technical and economic indicators of reconstructed irrigation pumping stations

The analysis of the reconstructed pumping stations showed that most stations, despite their specific features (commercial operation year, different sources water intake, differences in designs hydraulic structures, connection schemes units and pressure communications), have a fairly standard set reconstruction works: main structures irrigation are more or less satisfactory condition, need partial restoration (replacement), equipment needs complete replacement, modernization. This allows us to conclude existing dependence stations' technical economic indicators. statistical carried out using applied computer programs allowed choose type empirical coefficients analytical dependences cost indicators on station's power flow/head. comparison dependencies best convergence is observed for formula K = 14·N0.64. can be used when selecting priority objects reconstruction.
