Abstract – The design of a pumping station must aim, in addition to satisfying the technical requirements of the beneficiary, the energy efficiency and the safety during operation. The study undertaken refers to the modernization of a water supply pumping station, a base station that takes water from the Danube-Black Sea Channel and discharges it into the CA1 supply channel. Investigations into the vulnerability caused by hydraulic shock were made by numerical simulation, aiming to find out the best variant to protect the main discharge duct using air chamber. From either technical or economical viewpoint, the recommended variant is a 15 m3 air chamber, much smaller than the existing air chamber of 28 m3.
Keywords – hydraulic pumps’s performance, hydraulic shock, numerical simulation, pumping systems.
