【 摘 要 】

Switching-off the parallel working pump units causes sudden discharge changes in parallelpipe lines, as a result of that hydraulic shocks takes place. The damping of these shocks can beachieved by the installation of the by-pass devices between the parallel lines of the piping system. Theanalytical calculations demonstrate that the reduction in hydraulic shocks reaches 40% andconsiderable part of the electric power (from 5 up to 21%) is economized by using the by-pass devices,the duration of pressure decline decreases by more than 1,5 times. Comparison of the calculationsbased on the developed algorithm with the results of practical studies at the pumping station (Syrdarya)has shown good convergence of analytical and experimental outcomes.
